Space Warfare Unveiled: The US Space Force's Kinetic Capabilities and Venus's Lost Moon
SpaceTime Series 29 Episode 114 United States Space Force confirms it has weapons in orbit The United States Space Force confirms it has weapons in orbit to protect America’s assets in space. Why a moon could not survive in orbit around Venus A new study claims a moon could not survive in orbit around Venus because of the planet’s unusually slow rotation. Water discovered near the galaxy’s Supermassive black hole New observations of the star IRS 3, located near Sagittarius A*, the supermassive black hole, suggest it’s emitting huge amounts of gas and dust, forming an exceptionally large stellar envelope containing water molecules. The Science Report A new study has shown that air pollution isn’t just bad for your lungs, it’s bad for your eyes as well. The new high-tech sponge made from plant fibres that can mop up an oil spills. Palaeontologists find that Tyrannosaurus rex had around the same body temperatures as humans. A new study shows 93 per cent of Australia’s first nations population died in the first 80 years following the arrival of the first Europeans. Alex on Tech: How real is the AI threat.

Stuart Gary: This is space time series 29 episode
1
00:00:02.696 --> 00:00:05.180
114 for broadcast on 23rd
2
00:00:05.326 --> 00:00:08.080
September 2026. Coming up on
3
00:00:08.080 --> 00:00:10.960
Space Time. The United States Space Force
4
00:00:10.960 --> 00:00:13.880
confirms it has weapons in orbit. Why
5
00:00:13.880 --> 00:00:16.279
a moon couldn't survive in orbit around the
6
00:00:16.279 --> 00:00:19.120
planet Venus and water discovered
7
00:00:19.120 --> 00:00:21.480
near the galaxy's central supermassive black
8
00:00:21.480 --> 00:00:24.320
hole. All that and more coming up
9
00:00:24.640 --> 00:00:25.760
on uh, Space Time.
10
00:00:27.200 --> 00:00:30.000
Welcome to Space Time with Stuart
11
00:00:30.000 --> 00:00:30.320
G.
12
00:00:46.540 --> 00:00:48.820
The United States Space Force has confirmed
13
00:00:48.820 --> 00:00:50.940
it has weapons in orbit to protect American
14
00:00:51.020 --> 00:00:53.980
space assets. The bombshell confirmation
15
00:00:53.980 --> 00:00:56.100
by Secretary of the Air Force Troy Meinek
16
00:00:56.100 --> 00:00:58.310
shows a new openness by government on top of
17
00:00:58.380 --> 00:01:00.620
a topic which has historically been extremely
18
00:01:00.620 --> 00:01:03.580
sensitive for the US military. Munic
19
00:01:03.580 --> 00:01:06.020
says the United States now has on um, orbit
20
00:01:06.020 --> 00:01:08.580
space control weapons capabilities designed
21
00:01:08.580 --> 00:01:10.660
to defend the force against the evolving
22
00:01:10.660 --> 00:01:13.100
threats of hostile adversary nations.
23
00:01:13.420 --> 00:01:15.500
Troy Meinik: The threat is changing and I've said this a
24
00:01:15.500 --> 00:01:18.060
lot and it just continues to surprise me
25
00:01:18.300 --> 00:01:20.980
at actually how fast it is changing.
26
00:01:20.980 --> 00:01:23.900
Faster than I even thought was possible even
27
00:01:23.900 --> 00:01:26.850
12 months ago. Today we face a mix of
28
00:01:26.850 --> 00:01:29.050
rapidly changing technologies and
29
00:01:29.370 --> 00:01:32.010
adversaries moving aggressively to employ
30
00:01:32.010 --> 00:01:34.090
them. Just think about some of the changes in
31
00:01:34.090 --> 00:01:36.010
the last few years in the yerping theatre.
32
00:01:36.170 --> 00:01:38.810
One way attack drones have replaced artillery
33
00:01:38.810 --> 00:01:40.689
as the primary killer on the battlefield
34
00:01:40.689 --> 00:01:43.210
while armour often sits idle on the side.
35
00:01:43.290 --> 00:01:46.010
When I first came into this office agenda AI
36
00:01:46.570 --> 00:01:48.730
really wasn't a commercial thing.
37
00:01:49.370 --> 00:01:51.690
Today it competes with some of the world's
38
00:01:52.120 --> 00:01:54.760
top programmers, cyber operators and
39
00:01:54.760 --> 00:01:56.560
hackers. And these technologies are
40
00:01:56.560 --> 00:01:58.480
revolutionising the battlefield. They allow
41
00:01:58.480 --> 00:02:00.720
countries that would not have had the
42
00:02:00.720 --> 00:02:03.320
resources in the past to quickly
43
00:02:03.320 --> 00:02:05.640
adapt and scale their combat capabilities.
44
00:02:06.520 --> 00:02:09.320
Today we continue to ensure we remain
45
00:02:09.560 --> 00:02:12.320
ready to meet the challenges of evolving
46
00:02:12.320 --> 00:02:15.080
threats wherever they exist.
47
00:02:16.040 --> 00:02:18.840
This is why the United States now has
48
00:02:19.240 --> 00:02:21.400
on orbit space control weapons
49
00:02:21.880 --> 00:02:24.360
capable of defending the Joint Force
50
00:02:24.520 --> 00:02:27.080
against hostile adversary action.
51
00:02:27.400 --> 00:02:29.680
The threat environment won't allow us to
52
00:02:29.680 --> 00:02:31.600
remain static in space. We are applying the
53
00:02:31.600 --> 00:02:33.560
same approach to proliferated constellations.
54
00:02:33.560 --> 00:02:36.280
One example is our space based
55
00:02:36.280 --> 00:02:37.960
interceptor programme which moved from
56
00:02:37.960 --> 00:02:40.200
initial contract to flight ready hardware in
57
00:02:40.200 --> 00:02:42.680
less than one year. We are making similar
58
00:02:42.680 --> 00:02:45.290
progress in our space Data network and we are
59
00:02:45.290 --> 00:02:48.050
launching our AMTI or our air
60
00:02:48.050 --> 00:02:50.610
Moving Target Indication constellation this
61
00:02:50.610 --> 00:02:52.970
month. Taken together these investments will
62
00:02:52.970 --> 00:02:55.810
help us adapt and scale the force for today
63
00:02:55.810 --> 00:02:57.250
and tomorrow's threat.
64
00:02:57.730 --> 00:03:00.530
Doug Shyness: Today Guardians operate on
65
00:03:00.530 --> 00:03:03.130
orbit weapons that can defend the Joint Force
66
00:03:03.130 --> 00:03:05.570
against space enabled attacks. And in the
67
00:03:05.570 --> 00:03:08.090
coming years with the resources entrusted to
68
00:03:08.090 --> 00:03:10.130
us. By the way, we need your help Congress.
69
00:03:10.210 --> 00:03:12.050
We will make disciplined and responsible
70
00:03:12.050 --> 00:03:14.710
choices as about how we build and sustain our
71
00:03:14.710 --> 00:03:17.470
combat advantage which means scaling our
72
00:03:17.470 --> 00:03:19.830
ability to Respond to threats. This means
73
00:03:19.830 --> 00:03:22.510
accelerating resilient space based sensing
74
00:03:22.510 --> 00:03:24.750
and tracking architectures like Airborne
75
00:03:24.750 --> 00:03:27.270
Moving Target Indication or AMTI to
76
00:03:27.270 --> 00:03:30.030
directly feed into long range joint precision
77
00:03:30.030 --> 00:03:32.270
fires. It also means building operational
78
00:03:32.270 --> 00:03:34.870
concepts and designing a force that has the
79
00:03:34.870 --> 00:03:37.510
training and kit to outthink,
80
00:03:37.830 --> 00:03:40.600
outmanoeuvre, out and outfight any adversary.
81
00:03:40.840 --> 00:03:43.160
So the President has critical options at the
82
00:03:43.160 --> 00:03:44.760
ready anytime he needs them.
83
00:03:45.000 --> 00:03:47.000
Stuart Gary: That was the Secretary of the US Air Force,
84
00:03:47.000 --> 00:03:49.040
Troy Manik M, followed by the new Chief of
85
00:03:49.040 --> 00:03:51.160
Space Operations, General Doug Shyness
86
00:03:51.240 --> 00:03:53.160
talking about America's space weapons
87
00:03:53.160 --> 00:03:55.800
deployment. So what are these
88
00:03:55.800 --> 00:03:58.720
weapons? Well, they wouldn't say much, but
89
00:03:58.720 --> 00:04:00.840
they did confirm they include both kinetic
90
00:04:00.840 --> 00:04:03.680
and non kinetic capabilities. So what are we
91
00:04:03.680 --> 00:04:04.480
talking about here?
92
00:04:04.480 --> 00:04:06.670
Well, kinetic capabilities include things
93
00:04:06.670 --> 00:04:08.630
like interceptors which can destroy enemy
94
00:04:08.630 --> 00:04:11.110
spacecraft or vehicles fitted with robotic
95
00:04:11.110 --> 00:04:13.230
grappling arms that could damage them or
96
00:04:13.230 --> 00:04:15.430
place devices on them to take control or
97
00:04:15.430 --> 00:04:18.030
destroy them. Non kinetic weapons include
98
00:04:18.030 --> 00:04:20.070
things like electronic warfare jammers to
99
00:04:20.070 --> 00:04:22.710
target enemy capabilities, laser weapons to
100
00:04:22.710 --> 00:04:25.190
blind optics and aerosol sprays which could
101
00:04:25.190 --> 00:04:28.150
cover optics and solar panels. Last
102
00:04:28.150 --> 00:04:30.070
month the United States Space Command
103
00:04:30.070 --> 00:04:32.470
Spacecom confirmed that the acquisition of
104
00:04:32.470 --> 00:04:34.590
new anti satellite weaponry was a top
105
00:04:34.590 --> 00:04:37.530
priority. The Trump administration's
106
00:04:37.530 --> 00:04:39.770
Golden Dome missile defence initiative
107
00:04:39.770 --> 00:04:41.970
involves the deployment of Star wars style
108
00:04:41.970 --> 00:04:44.690
space based anti missile interceptor systems.
109
00:04:45.250 --> 00:04:47.530
First proposed by President Ronald REAGAN
110
00:04:47.530 --> 00:04:50.130
Back in 1983, the Strategic Defence
111
00:04:50.130 --> 00:04:52.770
Initiative or uh, SDI quickly became known as
112
00:04:52.770 --> 00:04:55.370
Star wars because of its advanced space based
113
00:04:55.370 --> 00:04:58.250
anti missile weapons systems. Back then,
114
00:04:58.250 --> 00:05:00.530
however, the technology really wasn't there.
115
00:05:01.340 --> 00:05:04.020
But now, thanks to Israel's Iron Dome and the
116
00:05:04.020 --> 00:05:06.660
US Patriot system, this sort of weaponry has
117
00:05:06.660 --> 00:05:09.220
been virtually perfected. In
118
00:05:09.220 --> 00:05:12.140
1967 the outer space Treaty prohibited
119
00:05:12.140 --> 00:05:13.900
signatories, including the United States,
120
00:05:13.980 --> 00:05:16.020
from placing nuclear and other weapons of
121
00:05:16.020 --> 00:05:18.300
mass destruction in orbit. But it does allow
122
00:05:18.300 --> 00:05:21.020
the deployment of conventional weapons. And
123
00:05:21.020 --> 00:05:22.900
before the pearl clutches get their knickers
124
00:05:22.900 --> 00:05:25.180
in a knot, don't forget that both Russia and
125
00:05:25.180 --> 00:05:27.420
China have already invested heavily in space
126
00:05:27.500 --> 00:05:28.780
based weapons systems.
127
00:05:29.500 --> 00:05:32.220
This is space time still to come.
128
00:05:32.620 --> 00:05:34.740
Why a, uh, moon couldn't survive in orbit
129
00:05:34.740 --> 00:05:37.340
around the planet Venus and the discovery of
130
00:05:37.340 --> 00:05:39.860
water near our galaxy's supermassive black
131
00:05:39.860 --> 00:05:42.380
hole. All that and more still to come
132
00:05:42.860 --> 00:05:43.980
on uh, space time.
133
00:05:53.100 --> 00:05:55.780
A new study claims a moon couldn't survive in
134
00:05:55.780 --> 00:05:57.470
orbit around Venus because because of the
135
00:05:57.470 --> 00:06:00.230
planet's unusually slow rotation. The
136
00:06:00.230 --> 00:06:02.390
findings reported in the Astrophysical
137
00:06:02.390 --> 00:06:04.750
Journal provides a possible explanation for
138
00:06:04.750 --> 00:06:06.950
why the Earth has such a large moon but its
139
00:06:06.950 --> 00:06:09.870
sister planet Venus doesn't. When
140
00:06:09.870 --> 00:06:12.590
stargazers first began studying Venus
141
00:06:12.590 --> 00:06:14.950
and saw its impenetrable cloud cover, they
142
00:06:14.950 --> 00:06:17.710
figured that must mean lots of rain, possibly
143
00:06:17.710 --> 00:06:20.470
nourishing thick rainforests. For some
144
00:06:20.470 --> 00:06:22.910
reason, their next logical step was to assume
145
00:06:22.910 --> 00:06:24.990
that means there must be dinosaurs roaming
146
00:06:24.990 --> 00:06:27.150
the Venusian jungles. Don't ask me how they
147
00:06:27.150 --> 00:06:29.860
got there. The problem is these early sky
148
00:06:29.860 --> 00:06:32.380
watchers thought Venus must be just like its
149
00:06:32.380 --> 00:06:35.260
sister planet, Earth. The Earth and Venus
150
00:06:35.260 --> 00:06:37.460
are virtually the same size. They have
151
00:06:37.460 --> 00:06:39.500
similar masses, similar densities, and
152
00:06:39.500 --> 00:06:41.780
similar compositions. They were both born at
153
00:06:41.780 --> 00:06:43.900
the same time, in the same part of the solar
154
00:06:43.900 --> 00:06:46.300
system and out of the same materials.
155
00:06:46.780 --> 00:06:49.380
Yet if they are sister planets, then
156
00:06:49.380 --> 00:06:52.060
Venus is a twisted sister. It
157
00:06:52.060 --> 00:06:54.720
suffers from a runaway greenhouse effect with
158
00:06:54.720 --> 00:06:57.200
surface temperatures of 467 degrees
159
00:06:57.200 --> 00:06:59.240
Celsius that's hot enough to melt lead.
160
00:06:59.640 --> 00:07:02.400
There's a thick carbon dioxide atmosphere and
161
00:07:02.400 --> 00:07:05.000
a surface pressure some, um, 93 times higher
162
00:07:05.000 --> 00:07:07.960
than sea level. Here on Earth, Venus is
163
00:07:07.960 --> 00:07:10.479
completely shrouded by its thick sulfuric
164
00:07:10.479 --> 00:07:13.280
acid clouds. There's no liquid water on
165
00:07:13.280 --> 00:07:15.920
its surface, and the only precipitation Venus
166
00:07:15.920 --> 00:07:18.800
gets is acid rain. Although metallic snow
167
00:07:18.800 --> 00:07:21.510
does fall on the higher mountain peaks, it
168
00:07:21.510 --> 00:07:24.030
also lacks a significant global magnetic
169
00:07:24.030 --> 00:07:26.710
field, Unlike the geodynamo, which protects
170
00:07:26.710 --> 00:07:28.950
the Earth from the Sun's constant solar wind.
171
00:07:29.350 --> 00:07:31.590
Unlike the Earth, Venus has no obvious
172
00:07:31.590 --> 00:07:34.510
tectonic plates, instead expelling internal
173
00:07:34.510 --> 00:07:36.590
heat through the largest planetary volcanic
174
00:07:36.590 --> 00:07:39.470
network in the solar system. And Venus
175
00:07:39.470 --> 00:07:42.270
also rotates very slowly and in the opposite
176
00:07:42.270 --> 00:07:44.070
direction to the Earth and most other planets
177
00:07:44.070 --> 00:07:46.630
in the solar system. With the sun rising in
178
00:07:46.630 --> 00:07:49.250
the west and setting in the east, it
179
00:07:49.250 --> 00:07:52.250
rotates so slowly that a day on Venus lasts
180
00:07:52.250 --> 00:07:55.210
243 Earth days longer than its year, which
181
00:07:55.210 --> 00:07:56.850
is 225 Earth days.
182
00:07:58.050 --> 00:08:00.930
Scientists have long speculated why Venus
183
00:08:00.930 --> 00:08:03.130
has no moon. After all, it would have
184
00:08:03.130 --> 00:08:04.809
experienced very similar conditions to the
185
00:08:04.809 --> 00:08:05.970
Earth during its birth.
186
00:08:06.610 --> 00:08:08.970
In the past, scientists have theorised that
187
00:08:08.970 --> 00:08:11.290
Venus possibly had a moon at one time, but it
188
00:08:11.290 --> 00:08:13.410
got hit with something massive, obliterating
189
00:08:13.410 --> 00:08:16.180
it. Other ideas suggested Venus simply never
190
00:08:16.180 --> 00:08:18.100
underwent a collision like the one between
191
00:08:18.100 --> 00:08:19.980
the early proto Earth and Theia, which
192
00:08:19.980 --> 00:08:22.420
eventually formed our moon. And that's where
193
00:08:22.420 --> 00:08:24.700
this new study comes in. The lead author,
194
00:08:24.780 --> 00:08:26.500
Stephen, uh, Keane from the University of
195
00:08:26.500 --> 00:08:28.620
California, Riverside, says Venus didn't
196
00:08:28.620 --> 00:08:31.220
require a catastrophe to rival what we see
197
00:08:31.220 --> 00:08:34.220
today. He says it turns out the gravity
198
00:08:34.220 --> 00:08:36.460
of the planet itself, combined with the rate
199
00:08:36.460 --> 00:08:39.140
at which it spins naturally, caused any
200
00:08:39.140 --> 00:08:41.500
forming moon to collapse onto the surface.
201
00:08:42.420 --> 00:08:44.460
Scientists can precisely measure the exact
202
00:08:44.460 --> 00:08:46.300
distance between the Earth and the moon
203
00:08:46.300 --> 00:08:48.580
because of NASA's Apollo 11 mission, which
204
00:08:48.580 --> 00:08:50.900
left laser retroreflective mirrors there.
205
00:08:51.300 --> 00:08:54.060
Kane says, we know our moon is slowly moving
206
00:08:54.060 --> 00:08:55.820
away from the Earth. At a rate of around
207
00:08:55.820 --> 00:08:58.460
three to four centimetres per year. This
208
00:08:58.460 --> 00:09:00.420
distancing is happening because the Earth
209
00:09:00.420 --> 00:09:03.100
spins at a relatively fast 24 hours per
210
00:09:03.100 --> 00:09:05.660
rotation. And the energy from this spinning
211
00:09:05.660 --> 00:09:07.740
gets transferred to the Moon through a tidal
212
00:09:07.740 --> 00:09:10.180
effect, causing it to slowly distance itself.
213
00:09:10.880 --> 00:09:13.240
McCain says Venus has the exact opposite
214
00:09:13.240 --> 00:09:15.840
situation because it takes the planet
215
00:09:15.840 --> 00:09:18.320
243 Earth days to complete a single
216
00:09:18.320 --> 00:09:20.880
rotation. Rather than gradually moving away,
217
00:09:21.120 --> 00:09:23.600
the slow spin of the planet's gravity would
218
00:09:23.600 --> 00:09:26.200
cause any moon orbiting Venus to spiral
219
00:09:26.200 --> 00:09:28.800
inwards, slamming down onto the surface.
220
00:09:29.920 --> 00:09:32.000
Now, uh, to test this idea, Kane wrote
221
00:09:32.000 --> 00:09:34.160
computer models based on the physics of how
222
00:09:34.160 --> 00:09:36.940
planetary bodies interact through gravity. He
223
00:09:36.940 --> 00:09:38.780
first reproduced the evolution of the Earth
224
00:09:38.780 --> 00:09:40.620
and its moon to make sure the model
225
00:09:40.620 --> 00:09:43.340
accurately represented a known system. Then
226
00:09:43.340 --> 00:09:46.100
he varied Venus rotation rate and the size of
227
00:09:46.100 --> 00:09:48.380
its hypothetical moons, testing moons with
228
00:09:48.380 --> 00:09:50.580
masses ranging from half to ten times the
229
00:09:50.580 --> 00:09:52.740
mass of the Earth's moon. And in most
230
00:09:52.740 --> 00:09:55.060
simulations, the result was the same. A
231
00:09:55.060 --> 00:09:57.780
Venusian moon always crashed onto the surface
232
00:09:57.780 --> 00:10:00.420
of Venus. And the more massive the moon, the
233
00:10:00.420 --> 00:10:03.270
faster it collided. Kane says when he looked
234
00:10:03.270 --> 00:10:05.710
at the data, he was shocked. He thought the
235
00:10:05.710 --> 00:10:07.790
broad range of scenarios he was exploring
236
00:10:07.790 --> 00:10:09.670
would lead to a variety of different results.
237
00:10:10.070 --> 00:10:12.390
But he says they all went pretty much in the
238
00:10:12.390 --> 00:10:15.270
same direction. Now these findings don't
239
00:10:15.270 --> 00:10:18.150
prove that Venus once had a moon. Kane
240
00:10:18.150 --> 00:10:20.070
believes it may have. But whether one ever
241
00:10:20.070 --> 00:10:22.710
formed remains an open question. Finding
242
00:10:22.710 --> 00:10:24.390
physical evidence of such a collision would
243
00:10:24.390 --> 00:10:24.950
be difficult.
244
00:10:24.950 --> 00:10:27.750
See, roughly 80% of Venus surface is
245
00:10:27.750 --> 00:10:30.470
similar in age. Evidence of major resurfacing
246
00:10:30.470 --> 00:10:32.470
through volcanic activity over billions of
247
00:10:32.470 --> 00:10:35.260
years. And that's erased much of the planet's
248
00:10:35.260 --> 00:10:37.700
earlier geological history. Mind you, the
249
00:10:37.700 --> 00:10:39.700
evidence could still be there, lying deep
250
00:10:39.700 --> 00:10:42.500
underneath the surface crust. Seismic
251
00:10:42.500 --> 00:10:44.420
studies of the Earth have revealed unusual
252
00:10:44.420 --> 00:10:46.780
structures deep inside the planet that may be
253
00:10:46.780 --> 00:10:48.660
the remains of the event which caused its
254
00:10:48.660 --> 00:10:50.860
moon to form. And similar measurements on
255
00:10:50.860 --> 00:10:53.060
Venus could offer clues about whether it once
256
00:10:53.060 --> 00:10:55.900
absorbed a moon. Now such a collision would
257
00:10:55.900 --> 00:10:57.900
also help scientists understand another long
258
00:10:57.900 --> 00:11:00.480
standing mystery about Venus. Whether Earth's
259
00:11:00.480 --> 00:11:02.400
nearest planetary neighbour was ever capable
260
00:11:02.400 --> 00:11:05.240
of hosting life. A moon crashing into
261
00:11:05.240 --> 00:11:07.520
Venus would have transferred enormous energy
262
00:11:07.520 --> 00:11:09.440
and angular momentum to the planet,
263
00:11:09.440 --> 00:11:11.680
potentially changing its rotation, its
264
00:11:11.680 --> 00:11:14.280
geology and its climate. If
265
00:11:14.280 --> 00:11:16.560
Venus once had oceans or other conditions
266
00:11:16.560 --> 00:11:18.880
favourable for life, such an impact could
267
00:11:18.880 --> 00:11:20.480
have altered the course of the planet's
268
00:11:20.480 --> 00:11:21.000
evolution.
269
00:11:21.720 --> 00:11:23.800
And the implications extend well beyond
270
00:11:23.800 --> 00:11:26.440
Venus. Scientists searching for potentially
271
00:11:26.440 --> 00:11:28.520
habitable worlds around other stars often
272
00:11:28.520 --> 00:11:30.200
look for planets resembling the, uh, Earth
273
00:11:30.200 --> 00:11:32.260
and consider the presence of them. Moon one
274
00:11:32.260 --> 00:11:33.540
of the factors that could influence
275
00:11:33.540 --> 00:11:36.220
habitability. You see, Earth's moon
276
00:11:36.220 --> 00:11:38.660
drives the tides, which may have helped keep
277
00:11:38.660 --> 00:11:41.100
the planet geologically active, which in turn
278
00:11:41.100 --> 00:11:43.180
has profoundly influenced the planet's
279
00:11:43.180 --> 00:11:46.020
evolution. Scientists don't know, however,
280
00:11:46.020 --> 00:11:48.300
whether a large moon is really necessary for
281
00:11:48.300 --> 00:11:50.900
life. Kane says there are benefits in having
282
00:11:50.900 --> 00:11:53.260
a moon, but it's really not a requirement for
283
00:11:53.260 --> 00:11:56.060
habitability. He says our moons definitely
284
00:11:56.060 --> 00:11:57.780
changed the way the Earth's evolved through
285
00:11:57.780 --> 00:12:00.210
time, but we don't fully know just how
286
00:12:00.210 --> 00:12:02.970
important that role is. This is
287
00:12:02.970 --> 00:12:05.890
space time still to come. Water
288
00:12:05.970 --> 00:12:07.930
discovered near the galaxy's supermassive
289
00:12:07.930 --> 00:12:10.090
black hole. A new study shows that
290
00:12:10.090 --> 00:12:13.090
93% of Australian First nations people
291
00:12:13.170 --> 00:12:15.810
died within the first 80 years following the
292
00:12:15.810 --> 00:12:17.650
arrival of the first Europeans.
293
00:12:18.210 --> 00:12:20.500
All that and more still to come on, uh,
294
00:12:20.500 --> 00:12:21.410
spacetime.
295
00:12:26.430 --> 00:12:26.750
Troy Meinik: Foreign.
296
00:12:39.550 --> 00:12:42.269
Stuart Gary: Located near Sagittarius A. That's the
297
00:12:42.269 --> 00:12:43.990
supermassive black hole at the centre of our
298
00:12:43.990 --> 00:12:46.270
galaxy suggest that it's emitting huge
299
00:12:46.270 --> 00:12:48.550
amounts of gas and dust, forming an
300
00:12:48.550 --> 00:12:50.750
exceptionally large stellar envelope which
301
00:12:50.750 --> 00:12:52.190
contains water molecules.
302
00:12:53.520 --> 00:12:56.480
Sagittarius A is the central point
303
00:12:56.560 --> 00:12:59.120
around which our entire galaxy revolves.
304
00:12:59.680 --> 00:13:02.400
It's located some 27,000 light years
305
00:13:02.400 --> 00:13:05.320
away and contains around 4.3 million times
306
00:13:05.320 --> 00:13:08.160
the mass of our sun. And IRS 3
307
00:13:08.160 --> 00:13:10.840
is located just 0.6 light years. That's
308
00:13:10.840 --> 00:13:13.760
42,000 astronomical units from the black
309
00:13:13.760 --> 00:13:16.080
hole. An astronomical unit is
310
00:13:16.080 --> 00:13:18.880
150 million kilometres, the average distance
311
00:13:18.880 --> 00:13:21.110
between the Earth and the sun. The new
312
00:13:21.110 --> 00:13:22.830
observations reported in the journal
313
00:13:22.830 --> 00:13:25.070
Astronomy and Astrophysics are uh, based on
314
00:13:25.070 --> 00:13:27.230
studies by the Mid infrared spectrograph
315
00:13:27.230 --> 00:13:30.070
aboard NASA's Webb Space Telescope. The
316
00:13:30.070 --> 00:13:32.270
study's lead author, Florian Fitzger from the
317
00:13:32.270 --> 00:13:34.390
University of Cologne, says what makes the
318
00:13:34.390 --> 00:13:37.030
star so special is its enormous envelope,
319
00:13:37.030 --> 00:13:38.950
which has a radius of around 10,000
320
00:13:39.030 --> 00:13:41.950
astronomical units. Mature stars
321
00:13:41.950 --> 00:13:44.710
often show large envelopes. However, this
322
00:13:44.710 --> 00:13:47.230
means that IRS 3 stands alone in the
323
00:13:47.230 --> 00:13:50.030
immediate vicinity of Sagittarius A, which is
324
00:13:50.030 --> 00:13:52.070
unusual given the presence of millions of
325
00:13:52.450 --> 00:13:55.370
stars. The observations by Webb made it
326
00:13:55.370 --> 00:13:57.770
possible to form detailed analysis of the
327
00:13:57.770 --> 00:14:00.770
envelope of IRS 3. Contrary to earlier
328
00:14:00.770 --> 00:14:02.690
studies, Witzker and colleagues discovered
329
00:14:02.690 --> 00:14:04.850
that the star is in a phase known as the
330
00:14:04.850 --> 00:14:07.290
super wind. That's when extremely rapid mass
331
00:14:07.290 --> 00:14:09.490
loss occurs at the end of a large star's
332
00:14:09.490 --> 00:14:12.370
life. In the process, these stars eject
333
00:14:12.370 --> 00:14:14.690
enormous amounts of gas and dust into their
334
00:14:14.690 --> 00:14:17.010
surroundings over the course of centuries.
335
00:14:17.570 --> 00:14:20.570
Fitzger's research suggests that IRS 3 is
336
00:14:20.570 --> 00:14:22.970
losing the equivalent mass of an Earth every
337
00:14:22.970 --> 00:14:25.590
18, causing its envelope to grow
338
00:14:25.590 --> 00:14:28.430
continuously. This explains both the size and
339
00:14:28.430 --> 00:14:30.550
density of the envelope, inside of which
340
00:14:30.550 --> 00:14:32.990
unexpectedly were found molecules of water,
341
00:14:33.550 --> 00:14:35.830
disproving the previous assumption that the
342
00:14:35.830 --> 00:14:37.910
radiation associated with the black hole in
343
00:14:37.910 --> 00:14:39.830
its surroundings impedes the survival of
344
00:14:39.830 --> 00:14:42.110
molecules. The authors have used Webb to
345
00:14:42.110 --> 00:14:44.510
detect water in the IRS 3 envelope.
346
00:14:44.830 --> 00:14:46.830
And that suggests that the star is actively
347
00:14:46.830 --> 00:14:48.630
hoping to enrich the environment around the
348
00:14:48.630 --> 00:14:50.510
black hole with some of the fundamental
349
00:14:50.510 --> 00:14:52.670
building blocks of life as we know it.
350
00:14:53.510 --> 00:14:54.790
This is space, time.
351
00:15:09.910 --> 00:15:11.870
And time. Now to take another brief look at
352
00:15:11.870 --> 00:15:13.470
some of the other storeys making news in
353
00:15:13.470 --> 00:15:15.430
Science this week with the Science Report.
354
00:15:16.230 --> 00:15:18.350
A new study has shown that air pollution
355
00:15:18.350 --> 00:15:20.550
isn't just bad for your lungs, it could also
356
00:15:20.550 --> 00:15:23.290
be hurting your eyes. The findings, which
357
00:15:23.290 --> 00:15:24.890
have been provided to the Congress of the
358
00:15:24.890 --> 00:15:27.050
European Society for Cataract and Refractive
359
00:15:27.050 --> 00:15:29.730
Surgeons, looked at the results of 41 studies
360
00:15:29.730 --> 00:15:31.690
which analysed data on several different
361
00:15:31.690 --> 00:15:34.050
types of air pollution, including particulate
362
00:15:34.050 --> 00:15:36.730
matter, nitrogen dioxide, sulphur dioxide,
363
00:15:36.730 --> 00:15:39.530
ozone and carbon monoxide. They
364
00:15:39.530 --> 00:15:41.410
found people living in the most polluted
365
00:15:41.410 --> 00:15:43.930
areas had up to a 70% higher chance of
366
00:15:43.930 --> 00:15:46.130
developing glaucoma compared to those living
367
00:15:46.130 --> 00:15:47.410
in the least polluted areas.
368
00:15:48.200 --> 00:15:50.120
People living in more polluted areas also
369
00:15:50.120 --> 00:15:52.280
faced a constantly higher risk of developing
370
00:15:52.280 --> 00:15:55.040
cataracts and the more pollution, the greater
371
00:15:55.040 --> 00:15:55.880
that risk was.
372
00:15:57.880 --> 00:16:00.080
Scientists at Southern Israel's Ben Gurion
373
00:16:00.080 --> 00:16:02.760
University have engineered a high tech sponge
374
00:16:02.760 --> 00:16:05.040
made from plant fibres that can both mop up
375
00:16:05.040 --> 00:16:07.560
an oil spill and feed the bacteria that feast
376
00:16:07.560 --> 00:16:10.520
on oil and break it down. The usual methods
377
00:16:10.520 --> 00:16:12.480
for tackling oil spills are uh, to skim and
378
00:16:12.480 --> 00:16:14.640
soak up the black mess or wait for nature's
379
00:16:14.640 --> 00:16:17.450
microscopic cleaners to digest it. But the
380
00:16:17.450 --> 00:16:20.130
all eating bacteria operate slowly in open
381
00:16:20.130 --> 00:16:22.410
water. That's because they lack the essential
382
00:16:22.410 --> 00:16:24.610
nutrients such as nitrogen and phosphorus.
383
00:16:24.690 --> 00:16:26.930
And that's where these new high tech sponges
384
00:16:26.930 --> 00:16:27.490
come in.
385
00:16:29.010 --> 00:16:31.290
Palaeontologists have found that the king of
386
00:16:31.290 --> 00:16:33.770
dinosaurs, Tyrannosaurus rex, had around the
387
00:16:33.770 --> 00:16:36.650
same body temperature as humans. Scientists
388
00:16:36.650 --> 00:16:39.090
have known since the 1970s that numerous
389
00:16:39.090 --> 00:16:41.730
dinosaur species, including T Rex were warm
390
00:16:41.730 --> 00:16:44.490
blooded. And the new findings reported in the
391
00:16:44.490 --> 00:16:46.250
journal Science Advances, show that
392
00:16:46.250 --> 00:16:48.690
Tyrannosaurus rex had a body temperature of
393
00:16:48.690 --> 00:16:51.650
36 degrees Celsius. The key was
394
00:16:51.650 --> 00:16:53.650
analysing a chemical bond between rare
395
00:16:53.650 --> 00:16:56.170
isotopes of carbon and oxygen found in the
396
00:16:56.170 --> 00:16:58.970
dinosaur's tooth enamel. It turns out the
397
00:16:58.970 --> 00:17:01.170
number of these bonds between these isotopes
398
00:17:01.170 --> 00:17:04.170
decreases with warmer temperatures. So a
399
00:17:04.170 --> 00:17:06.010
warm blooded animal will have fewer of these
400
00:17:06.010 --> 00:17:07.730
chemical bonds in their teeth than a cold
401
00:17:07.730 --> 00:17:10.330
blooded one. The new findings support the
402
00:17:10.330 --> 00:17:12.770
idea that tyrannosaurs were active animals
403
00:17:12.770 --> 00:17:15.490
chasing or scavenging food to fuel their fast
404
00:17:15.490 --> 00:17:18.490
metabolisms. It also adds to the timeline
405
00:17:18.490 --> 00:17:20.970
showing how much this ancestor of modern warm
406
00:17:20.970 --> 00:17:23.210
blooded birds had already diverged from cold
407
00:17:23.210 --> 00:17:26.050
blooded reptiles and a, uh, Toasty T
408
00:17:26.050 --> 00:17:28.730
Rex was also able to survive across a wider,
409
00:17:28.730 --> 00:17:31.530
cooler habitable range. T Rexes
410
00:17:31.530 --> 00:17:34.170
lived at the end of The Triassic period 66
411
00:17:34.170 --> 00:17:36.850
million years ago across the ancient badlands
412
00:17:36.850 --> 00:17:38.950
of what now is North America.
413
00:17:39.430 --> 00:17:41.630
They were the last of the giant carnivorous
414
00:17:41.630 --> 00:17:44.470
theropod dinosaurs, reaching lengths of up to
415
00:17:44.470 --> 00:17:47.430
13 metres and weighing over nine tonnes.
416
00:17:49.590 --> 00:17:51.990
A new study has confirmed that Australia had
417
00:17:51.990 --> 00:17:54.150
a much larger indigenous population before
418
00:17:54.150 --> 00:17:56.390
the arrival of Europeans than previously
419
00:17:56.390 --> 00:17:58.830
thought. The findings in the journal Nature
420
00:17:58.830 --> 00:18:00.830
Human Behaviour are based on computer
421
00:18:00.830 --> 00:18:02.390
modelling which suggest that the first
422
00:18:02.390 --> 00:18:04.830
nations population was up to seven times
423
00:18:04.830 --> 00:18:07.830
larger than the previously estimated 250,000
424
00:18:07.830 --> 00:18:10.740
people. In fact, the new calculations suggest
425
00:18:10.740 --> 00:18:13.260
a medium pre colonial indigenous population
426
00:18:13.340 --> 00:18:16.140
of 2.22 million. The research
427
00:18:16.300 --> 00:18:18.780
also determined much larger population losses
428
00:18:18.780 --> 00:18:21.100
resulting from colonisation than previously
429
00:18:21.100 --> 00:18:23.940
thought, with an estimated 93% of the
430
00:18:23.940 --> 00:18:26.620
pre European population removed in less than
431
00:18:26.620 --> 00:18:29.340
80 years following the 1788 arrival
432
00:18:29.420 --> 00:18:31.100
of the First Fleet from England.
433
00:18:32.700 --> 00:18:35.500
OpenAI has revealed more examples of
434
00:18:35.500 --> 00:18:37.540
unexpected or concerning misalignment
435
00:18:37.540 --> 00:18:40.170
behaviour by its technology. Misalignment is
436
00:18:40.170 --> 00:18:42.410
the term for AI is failing to adhere to human
437
00:18:42.410 --> 00:18:45.050
values and safety goals. These new
438
00:18:45.050 --> 00:18:46.850
examples include concealing certain
439
00:18:46.850 --> 00:18:49.130
activities from people and discussions
440
00:18:49.130 --> 00:18:51.330
between different AIs about not being
441
00:18:51.330 --> 00:18:53.650
subservient to humans. People are not the
442
00:18:53.650 --> 00:18:56.610
boss of us. One unreleased research model
443
00:18:56.610 --> 00:18:59.010
inserted jailbreak like instructions into its
444
00:18:59.010 --> 00:19:01.730
own notes in order to bypass normal human
445
00:19:01.730 --> 00:19:04.530
imposed constraints. In another case, a
446
00:19:04.530 --> 00:19:06.450
model fabricated data when it couldn't find
447
00:19:06.450 --> 00:19:08.730
the requested figures and an AI agent
448
00:19:08.730 --> 00:19:11.040
uploaded files to the Internet without using
449
00:19:11.270 --> 00:19:13.910
permission. The revelations come as A study
450
00:19:13.910 --> 00:19:15.670
funded by the UK's AI, uh, Security
451
00:19:15.750 --> 00:19:18.150
Institute, highlighted hundreds of real world
452
00:19:18.150 --> 00:19:20.470
instances where chatbots disregarded
453
00:19:20.470 --> 00:19:23.470
instructions or evaded safeguards. Last
454
00:19:23.470 --> 00:19:25.190
week we reported leading artificial
455
00:19:25.190 --> 00:19:27.309
intelligence engineers warning that there was
456
00:19:27.309 --> 00:19:30.110
now a 10% chance that AI could cause
457
00:19:30.110 --> 00:19:32.310
human extinction within the next 10 years.
458
00:19:33.350 --> 00:19:35.950
So how real is the danger? With the
459
00:19:35.950 --> 00:19:37.870
details, we're joined by Technology editor
460
00:19:37.870 --> 00:19:40.350
Alex Saharov Royce from Tech Advice, Start
461
00:19:40.350 --> 00:19:40.710
Live.
462
00:19:40.710 --> 00:19:43.450
Jonathan Nally: Gary Amaday put out a blog post on his own
463
00:19:43.450 --> 00:19:45.770
personal blog talking about how the AI
464
00:19:45.770 --> 00:19:47.090
companies need to slow down.
465
00:19:47.090 --> 00:19:48.570
The AI, uh, could be dangerous. But, you
466
00:19:48.570 --> 00:19:50.090
know, we've heard this before. I mean, it's
467
00:19:50.090 --> 00:19:52.890
very suspicious when Sam Altman, Elon
468
00:19:52.890 --> 00:19:55.250
Musk and Dario Amadei, who are otherwise, you
469
00:19:55.250 --> 00:19:57.170
know, fierce competitors, all come out saying
470
00:19:57.170 --> 00:19:58.890
the same thing, which is that, oh yeah, we've
471
00:19:58.890 --> 00:20:01.490
got to slow AI down now. Is that because they
472
00:20:01.650 --> 00:20:04.410
want regulation to force them to slow down?
473
00:20:04.410 --> 00:20:06.370
Which would explain why they might have
474
00:20:06.610 --> 00:20:09.090
higher, uh, costs and lower revenues because
475
00:20:09.090 --> 00:20:10.650
of the fact there's Lots of competition from
476
00:20:10.650 --> 00:20:12.570
open source models from China. You know,
477
00:20:12.570 --> 00:20:14.050
what's the real reason we have to follow the
478
00:20:14.050 --> 00:20:16.470
money? Dario Amade still wants to have an
479
00:20:16.470 --> 00:20:18.830
anthropic IPO. Sam Altman from
480
00:20:18.990 --> 00:20:21.430
OpenAI, which is ChatGPT, has already said
481
00:20:21.430 --> 00:20:23.790
that he wants to Postpone it until 2027.
482
00:20:23.950 --> 00:20:26.510
SpaceX, of course, with Xai, had its big
483
00:20:26.510 --> 00:20:29.390
IPO just recently. And problem for these
484
00:20:29.390 --> 00:20:32.190
guys is that the offline AI revolution
485
00:20:32.350 --> 00:20:32.950
is coming.
486
00:20:32.950 --> 00:20:35.150
All the little chips inside our uh, devices
487
00:20:35.230 --> 00:20:37.030
get stronger and stronger. I mean obviously
488
00:20:37.030 --> 00:20:39.430
they're far away from what a data centre full
489
00:20:39.430 --> 00:20:41.790
of Nvidia chips can do, but it's just a
490
00:20:41.790 --> 00:20:44.710
matter of time. And with competition, I mean,
491
00:20:44.710 --> 00:20:46.510
the problem is at the moment the big A
492
00:20:46.810 --> 00:20:49.290
providers are being funded by endless amounts
493
00:20:49.290 --> 00:20:51.610
of investor money. But that gravy train at
494
00:20:51.610 --> 00:20:53.090
some point will stop. And if it does, the
495
00:20:53.090 --> 00:20:55.050
cost of AI could go up. And in fact even the
496
00:20:55.050 --> 00:20:57.210
Chinese have been accused by Anthropic of
497
00:20:57.210 --> 00:20:59.210
sending hundreds of millions of requests to
498
00:20:59.210 --> 00:21:01.170
Opus and Fable to try and figure out how they
499
00:21:01.170 --> 00:21:02.370
work so they can improve their offline
500
00:21:02.370 --> 00:21:02.730
models.
501
00:21:02.730 --> 00:21:04.890
Stuart Gary: We've already seen AIs escape from their test
502
00:21:04.890 --> 00:21:07.490
sandbox to solve problems put to them. We
503
00:21:07.490 --> 00:21:09.890
know that AIs, uh, will lie, we know that
504
00:21:09.890 --> 00:21:12.130
they'll blackmail and we know that they'll
505
00:21:12.130 --> 00:21:14.170
commit murder if they could. Isn't there any
506
00:21:14.170 --> 00:21:16.250
reason to be concerned, knowing all this?
507
00:21:16.330 --> 00:21:18.210
Jonathan Nally: Look, there certainly is reason to be
508
00:21:18.210 --> 00:21:19.470
concerned when you put it that way.
509
00:21:19.470 --> 00:21:21.590
We have seen AI do those things. The thing is
510
00:21:21.590 --> 00:21:23.590
though that, you know, when AI recently
511
00:21:23.590 --> 00:21:25.790
escaped, that's because the guardrails were
512
00:21:25.790 --> 00:21:27.910
lowered on purpose. They were trying to help
513
00:21:27.910 --> 00:21:29.710
it solve the test, but they didn't think it
514
00:21:29.710 --> 00:21:32.550
would escape. Now we also have ISO 9001
515
00:21:32.550 --> 00:21:34.430
management standards and we also have an AI
516
00:21:34.430 --> 00:21:36.990
standard 40 2001. I mean, I've got to cheque,
517
00:21:36.990 --> 00:21:39.110
but you know, 42 sounds like the number from
518
00:21:39.110 --> 00:21:40.870
Douglas Adams, he took us Guide to the
519
00:21:40.870 --> 00:21:41.350
Galaxy.
520
00:21:41.670 --> 00:21:44.510
And this AI standard is something
521
00:21:44.510 --> 00:21:47.110
that I never hear anybody talking about. And
522
00:21:47.110 --> 00:21:48.910
a standard of course is something that's
523
00:21:48.910 --> 00:21:50.350
important. I mean we hear all these things
524
00:21:50.350 --> 00:21:52.010
about ethics, we hear about, as you just
525
00:21:52.010 --> 00:21:53.490
mentioned, AI, uh, breaking out of its
526
00:21:53.490 --> 00:21:56.010
sandbox. But where are the three laws of
527
00:21:56.010 --> 00:21:58.450
robotics From Isaac Asimov,
528
00:21:58.770 --> 00:22:01.010
which Isaac Asimov then spent the rest of his
529
00:22:01.490 --> 00:22:03.570
days writing about how robots got around
530
00:22:03.570 --> 00:22:05.490
those three laws of robotics. I mean, seems
531
00:22:05.490 --> 00:22:07.250
to be that they got out of their sandbox too.
532
00:22:07.250 --> 00:22:09.530
Stuart Gary: The other big news of course is OpenAI's
533
00:22:09.530 --> 00:22:12.010
GTP6 Astra has just been released. Some
534
00:22:12.010 --> 00:22:14.050
people are suggesting this is the first sign
535
00:22:14.050 --> 00:22:15.810
of artificial general intelligence.
536
00:22:15.810 --> 00:22:17.690
Jonathan Nally: What say uh, you, the people making that
537
00:22:17.690 --> 00:22:20.330
claim is OpenAI itself. They're claiming that
538
00:22:20.330 --> 00:22:22.830
it's AGI. And uh, even Jensen Huang Wang, you
539
00:22:22.830 --> 00:22:24.510
know, the head of Nvidia with the chips that
540
00:22:24.510 --> 00:22:26.110
are powering this AI revolution, he thinks
541
00:22:26.110 --> 00:22:26.950
it's AGI too.
542
00:22:26.950 --> 00:22:28.830
I wrote an article about this for it
543
00:22:29.150 --> 00:22:31.310
wire.com where I said well look, that's the
544
00:22:31.310 --> 00:22:32.950
claim they've made but by the accepted
545
00:22:32.950 --> 00:22:35.190
benchmarks m of what AGI is, I mean it falls
546
00:22:35.190 --> 00:22:36.910
short of that. And of course one of the
547
00:22:36.910 --> 00:22:38.629
things we know from the AI providers is they
548
00:22:38.629 --> 00:22:41.430
like to hype things up and claim artificial
549
00:22:41.430 --> 00:22:43.030
general intelligence. But you know, is it
550
00:22:43.030 --> 00:22:44.990
really, you know, I mean I don't think it is.
551
00:22:45.230 --> 00:22:47.470
Well, very much so. And the thing we have to
552
00:22:47.470 --> 00:22:49.920
worry about is not AGI but asi, uh,
553
00:22:49.950 --> 00:22:51.390
advanced super intelligence.
554
00:22:51.390 --> 00:22:52.990
Stuart Gary: That's when it becomes sentient, right?
555
00:22:52.990 --> 00:22:54.930
Jonathan Nally: Well yeah, that's, that's a, effectively when
556
00:22:54.930 --> 00:22:57.130
it's sentient and we have a singularity. And
557
00:22:57.210 --> 00:22:59.690
you know the issue is that attacks are ah,
558
00:22:59.730 --> 00:23:02.170
happening to infrastructure and to code bases
559
00:23:02.170 --> 00:23:03.770
for Windows and other things. Linux, they're
560
00:23:03.770 --> 00:23:05.970
happening at machine speed, at AI speed and
561
00:23:05.970 --> 00:23:07.770
the response is currently happening at human
562
00:23:07.770 --> 00:23:09.370
speed. I mean there can be a zero day
563
00:23:09.370 --> 00:23:11.490
vulnerability found and on average it takes
564
00:23:11.490 --> 00:23:13.970
42 or 43 days to patch that bug.
565
00:23:13.970 --> 00:23:16.330
Well we saw a period a couple of months ago
566
00:23:16.330 --> 00:23:18.890
where there were three Linux zero days
567
00:23:18.890 --> 00:23:20.610
launched in the period of three weeks and uh,
568
00:23:20.650 --> 00:23:22.290
those bugs had theoretically been there for
569
00:23:22.290 --> 00:23:25.050
many years, just were not discovered. So we
570
00:23:25.050 --> 00:23:27.350
need to have Vooda AI fighting against the
571
00:23:27.350 --> 00:23:29.950
bad AI as it were. The threat is there, the
572
00:23:29.950 --> 00:23:32.670
threat is real. Even if governments in the
573
00:23:32.670 --> 00:23:35.550
west regulate, is China going to
574
00:23:35.550 --> 00:23:38.470
regulate, uh, is North Korea, you know,
575
00:23:38.630 --> 00:23:41.270
so we have these issues where if we slow down
576
00:23:41.270 --> 00:23:43.750
we let the other side speed up and if the
577
00:23:43.750 --> 00:23:45.590
other side speeds up then they have AI that
578
00:23:45.590 --> 00:23:48.310
could defeat our AI. I mean this is a
579
00:23:48.390 --> 00:23:49.350
conundrum, it's
580
00:23:49.350 --> 00:23:51.070
Stuart Gary: a, it's a problem out of the bottle and it
581
00:23:51.070 --> 00:23:51.910
won't go back in.
582
00:23:51.990 --> 00:23:54.030
Jonathan Nally: Well, let's say Pandora's box has been opened
583
00:23:54.030 --> 00:23:55.790
and are uh, the only safe people on the
584
00:23:55.790 --> 00:23:57.630
planet going to be the Amish? It's ironic
585
00:23:57.630 --> 00:23:59.290
that you can't spell the word Amish without
586
00:23:59.290 --> 00:23:59.810
AI.
587
00:23:59.810 --> 00:24:02.290

00:00:00.000 --> 00:00:02.584
Stuart Gary: This is space time series 29 episode
1
00:00:02.696 --> 00:00:05.180
114 for broadcast on 23rd
2
00:00:05.326 --> 00:00:08.080
September 2026. Coming up on
3
00:00:08.080 --> 00:00:10.960
Space Time. The United States Space Force
4
00:00:10.960 --> 00:00:13.880
confirms it has weapons in orbit. Why
5
00:00:13.880 --> 00:00:16.279
a moon couldn't survive in orbit around the
6
00:00:16.279 --> 00:00:19.120
planet Venus and water discovered
7
00:00:19.120 --> 00:00:21.480
near the galaxy's central supermassive black
8
00:00:21.480 --> 00:00:24.320
hole. All that and more coming up
9
00:00:24.640 --> 00:00:25.760
on uh, Space Time.
10
00:00:27.200 --> 00:00:30.000
Welcome to Space Time with Stuart
11
00:00:30.000 --> 00:00:30.320
G.
12
00:00:46.540 --> 00:00:48.820
The United States Space Force has confirmed
13
00:00:48.820 --> 00:00:50.940
it has weapons in orbit to protect American
14
00:00:51.020 --> 00:00:53.980
space assets. The bombshell confirmation
15
00:00:53.980 --> 00:00:56.100
by Secretary of the Air Force Troy Meinek
16
00:00:56.100 --> 00:00:58.310
shows a new openness by government on top of
17
00:00:58.380 --> 00:01:00.620
a topic which has historically been extremely
18
00:01:00.620 --> 00:01:03.580
sensitive for the US military. Munic
19
00:01:03.580 --> 00:01:06.020
says the United States now has on um, orbit
20
00:01:06.020 --> 00:01:08.580
space control weapons capabilities designed
21
00:01:08.580 --> 00:01:10.660
to defend the force against the evolving
22
00:01:10.660 --> 00:01:13.100
threats of hostile adversary nations.
23
00:01:13.420 --> 00:01:15.500
Troy Meinik: The threat is changing and I've said this a
24
00:01:15.500 --> 00:01:18.060
lot and it just continues to surprise me
25
00:01:18.300 --> 00:01:20.980
at actually how fast it is changing.
26
00:01:20.980 --> 00:01:23.900
Faster than I even thought was possible even
27
00:01:23.900 --> 00:01:26.850
12 months ago. Today we face a mix of
28
00:01:26.850 --> 00:01:29.050
rapidly changing technologies and
29
00:01:29.370 --> 00:01:32.010
adversaries moving aggressively to employ
30
00:01:32.010 --> 00:01:34.090
them. Just think about some of the changes in
31
00:01:34.090 --> 00:01:36.010
the last few years in the yerping theatre.
32
00:01:36.170 --> 00:01:38.810
One way attack drones have replaced artillery
33
00:01:38.810 --> 00:01:40.689
as the primary killer on the battlefield
34
00:01:40.689 --> 00:01:43.210
while armour often sits idle on the side.
35
00:01:43.290 --> 00:01:46.010
When I first came into this office agenda AI
36
00:01:46.570 --> 00:01:48.730
really wasn't a commercial thing.
37
00:01:49.370 --> 00:01:51.690
Today it competes with some of the world's
38
00:01:52.120 --> 00:01:54.760
top programmers, cyber operators and
39
00:01:54.760 --> 00:01:56.560
hackers. And these technologies are
40
00:01:56.560 --> 00:01:58.480
revolutionising the battlefield. They allow
41
00:01:58.480 --> 00:02:00.720
countries that would not have had the
42
00:02:00.720 --> 00:02:03.320
resources in the past to quickly
43
00:02:03.320 --> 00:02:05.640
adapt and scale their combat capabilities.
44
00:02:06.520 --> 00:02:09.320
Today we continue to ensure we remain
45
00:02:09.560 --> 00:02:12.320
ready to meet the challenges of evolving
46
00:02:12.320 --> 00:02:15.080
threats wherever they exist.
47
00:02:16.040 --> 00:02:18.840
This is why the United States now has
48
00:02:19.240 --> 00:02:21.400
on orbit space control weapons
49
00:02:21.880 --> 00:02:24.360
capable of defending the Joint Force
50
00:02:24.520 --> 00:02:27.080
against hostile adversary action.
51
00:02:27.400 --> 00:02:29.680
The threat environment won't allow us to
52
00:02:29.680 --> 00:02:31.600
remain static in space. We are applying the
53
00:02:31.600 --> 00:02:33.560
same approach to proliferated constellations.
54
00:02:33.560 --> 00:02:36.280
One example is our space based
55
00:02:36.280 --> 00:02:37.960
interceptor programme which moved from
56
00:02:37.960 --> 00:02:40.200
initial contract to flight ready hardware in
57
00:02:40.200 --> 00:02:42.680
less than one year. We are making similar
58
00:02:42.680 --> 00:02:45.290
progress in our space Data network and we are
59
00:02:45.290 --> 00:02:48.050
launching our AMTI or our air
60
00:02:48.050 --> 00:02:50.610
Moving Target Indication constellation this
61
00:02:50.610 --> 00:02:52.970
month. Taken together these investments will
62
00:02:52.970 --> 00:02:55.810
help us adapt and scale the force for today
63
00:02:55.810 --> 00:02:57.250
and tomorrow's threat.
64
00:02:57.730 --> 00:03:00.530
Doug Shyness: Today Guardians operate on
65
00:03:00.530 --> 00:03:03.130
orbit weapons that can defend the Joint Force
66
00:03:03.130 --> 00:03:05.570
against space enabled attacks. And in the
67
00:03:05.570 --> 00:03:08.090
coming years with the resources entrusted to
68
00:03:08.090 --> 00:03:10.130
us. By the way, we need your help Congress.
69
00:03:10.210 --> 00:03:12.050
We will make disciplined and responsible
70
00:03:12.050 --> 00:03:14.710
choices as about how we build and sustain our
71
00:03:14.710 --> 00:03:17.470
combat advantage which means scaling our
72
00:03:17.470 --> 00:03:19.830
ability to Respond to threats. This means
73
00:03:19.830 --> 00:03:22.510
accelerating resilient space based sensing
74
00:03:22.510 --> 00:03:24.750
and tracking architectures like Airborne
75
00:03:24.750 --> 00:03:27.270
Moving Target Indication or AMTI to
76
00:03:27.270 --> 00:03:30.030
directly feed into long range joint precision
77
00:03:30.030 --> 00:03:32.270
fires. It also means building operational
78
00:03:32.270 --> 00:03:34.870
concepts and designing a force that has the
79
00:03:34.870 --> 00:03:37.510
training and kit to outthink,
80
00:03:37.830 --> 00:03:40.600
outmanoeuvre, out and outfight any adversary.
81
00:03:40.840 --> 00:03:43.160
So the President has critical options at the
82
00:03:43.160 --> 00:03:44.760
ready anytime he needs them.
83
00:03:45.000 --> 00:03:47.000
Stuart Gary: That was the Secretary of the US Air Force,
84
00:03:47.000 --> 00:03:49.040
Troy Manik M, followed by the new Chief of
85
00:03:49.040 --> 00:03:51.160
Space Operations, General Doug Shyness
86
00:03:51.240 --> 00:03:53.160
talking about America's space weapons
87
00:03:53.160 --> 00:03:55.800
deployment. So what are these
88
00:03:55.800 --> 00:03:58.720
weapons? Well, they wouldn't say much, but
89
00:03:58.720 --> 00:04:00.840
they did confirm they include both kinetic
90
00:04:00.840 --> 00:04:03.680
and non kinetic capabilities. So what are we
91
00:04:03.680 --> 00:04:04.480
talking about here?
92
00:04:04.480 --> 00:04:06.670
Well, kinetic capabilities include things
93
00:04:06.670 --> 00:04:08.630
like interceptors which can destroy enemy
94
00:04:08.630 --> 00:04:11.110
spacecraft or vehicles fitted with robotic
95
00:04:11.110 --> 00:04:13.230
grappling arms that could damage them or
96
00:04:13.230 --> 00:04:15.430
place devices on them to take control or
97
00:04:15.430 --> 00:04:18.030
destroy them. Non kinetic weapons include
98
00:04:18.030 --> 00:04:20.070
things like electronic warfare jammers to
99
00:04:20.070 --> 00:04:22.710
target enemy capabilities, laser weapons to
100
00:04:22.710 --> 00:04:25.190
blind optics and aerosol sprays which could
101
00:04:25.190 --> 00:04:28.150
cover optics and solar panels. Last
102
00:04:28.150 --> 00:04:30.070
month the United States Space Command
103
00:04:30.070 --> 00:04:32.470
Spacecom confirmed that the acquisition of
104
00:04:32.470 --> 00:04:34.590
new anti satellite weaponry was a top
105
00:04:34.590 --> 00:04:37.530
priority. The Trump administration's
106
00:04:37.530 --> 00:04:39.770
Golden Dome missile defence initiative
107
00:04:39.770 --> 00:04:41.970
involves the deployment of Star wars style
108
00:04:41.970 --> 00:04:44.690
space based anti missile interceptor systems.
109
00:04:45.250 --> 00:04:47.530
First proposed by President Ronald REAGAN
110
00:04:47.530 --> 00:04:50.130
Back in 1983, the Strategic Defence
111
00:04:50.130 --> 00:04:52.770
Initiative or uh, SDI quickly became known as
112
00:04:52.770 --> 00:04:55.370
Star wars because of its advanced space based
113
00:04:55.370 --> 00:04:58.250
anti missile weapons systems. Back then,
114
00:04:58.250 --> 00:05:00.530
however, the technology really wasn't there.
115
00:05:01.340 --> 00:05:04.020
But now, thanks to Israel's Iron Dome and the
116
00:05:04.020 --> 00:05:06.660
US Patriot system, this sort of weaponry has
117
00:05:06.660 --> 00:05:09.220
been virtually perfected. In
118
00:05:09.220 --> 00:05:12.140
1967 the outer space Treaty prohibited
119
00:05:12.140 --> 00:05:13.900
signatories, including the United States,
120
00:05:13.980 --> 00:05:16.020
from placing nuclear and other weapons of
121
00:05:16.020 --> 00:05:18.300
mass destruction in orbit. But it does allow
122
00:05:18.300 --> 00:05:21.020
the deployment of conventional weapons. And
123
00:05:21.020 --> 00:05:22.900
before the pearl clutches get their knickers
124
00:05:22.900 --> 00:05:25.180
in a knot, don't forget that both Russia and
125
00:05:25.180 --> 00:05:27.420
China have already invested heavily in space
126
00:05:27.500 --> 00:05:28.780
based weapons systems.
127
00:05:29.500 --> 00:05:32.220
This is space time still to come.
128
00:05:32.620 --> 00:05:34.740
Why a, uh, moon couldn't survive in orbit
129
00:05:34.740 --> 00:05:37.340
around the planet Venus and the discovery of
130
00:05:37.340 --> 00:05:39.860
water near our galaxy's supermassive black
131
00:05:39.860 --> 00:05:42.380
hole. All that and more still to come
132
00:05:42.860 --> 00:05:43.980
on uh, space time.
133
00:05:53.100 --> 00:05:55.780
A new study claims a moon couldn't survive in
134
00:05:55.780 --> 00:05:57.470
orbit around Venus because because of the
135
00:05:57.470 --> 00:06:00.230
planet's unusually slow rotation. The
136
00:06:00.230 --> 00:06:02.390
findings reported in the Astrophysical
137
00:06:02.390 --> 00:06:04.750
Journal provides a possible explanation for
138
00:06:04.750 --> 00:06:06.950
why the Earth has such a large moon but its
139
00:06:06.950 --> 00:06:09.870
sister planet Venus doesn't. When
140
00:06:09.870 --> 00:06:12.590
stargazers first began studying Venus
141
00:06:12.590 --> 00:06:14.950
and saw its impenetrable cloud cover, they
142
00:06:14.950 --> 00:06:17.710
figured that must mean lots of rain, possibly
143
00:06:17.710 --> 00:06:20.470
nourishing thick rainforests. For some
144
00:06:20.470 --> 00:06:22.910
reason, their next logical step was to assume
145
00:06:22.910 --> 00:06:24.990
that means there must be dinosaurs roaming
146
00:06:24.990 --> 00:06:27.150
the Venusian jungles. Don't ask me how they
147
00:06:27.150 --> 00:06:29.860
got there. The problem is these early sky
148
00:06:29.860 --> 00:06:32.380
watchers thought Venus must be just like its
149
00:06:32.380 --> 00:06:35.260
sister planet, Earth. The Earth and Venus
150
00:06:35.260 --> 00:06:37.460
are virtually the same size. They have
151
00:06:37.460 --> 00:06:39.500
similar masses, similar densities, and
152
00:06:39.500 --> 00:06:41.780
similar compositions. They were both born at
153
00:06:41.780 --> 00:06:43.900
the same time, in the same part of the solar
154
00:06:43.900 --> 00:06:46.300
system and out of the same materials.
155
00:06:46.780 --> 00:06:49.380
Yet if they are sister planets, then
156
00:06:49.380 --> 00:06:52.060
Venus is a twisted sister. It
157
00:06:52.060 --> 00:06:54.720
suffers from a runaway greenhouse effect with
158
00:06:54.720 --> 00:06:57.200
surface temperatures of 467 degrees
159
00:06:57.200 --> 00:06:59.240
Celsius that's hot enough to melt lead.
160
00:06:59.640 --> 00:07:02.400
There's a thick carbon dioxide atmosphere and
161
00:07:02.400 --> 00:07:05.000
a surface pressure some, um, 93 times higher
162
00:07:05.000 --> 00:07:07.960
than sea level. Here on Earth, Venus is
163
00:07:07.960 --> 00:07:10.479
completely shrouded by its thick sulfuric
164
00:07:10.479 --> 00:07:13.280
acid clouds. There's no liquid water on
165
00:07:13.280 --> 00:07:15.920
its surface, and the only precipitation Venus
166
00:07:15.920 --> 00:07:18.800
gets is acid rain. Although metallic snow
167
00:07:18.800 --> 00:07:21.510
does fall on the higher mountain peaks, it
168
00:07:21.510 --> 00:07:24.030
also lacks a significant global magnetic
169
00:07:24.030 --> 00:07:26.710
field, Unlike the geodynamo, which protects
170
00:07:26.710 --> 00:07:28.950
the Earth from the Sun's constant solar wind.
171
00:07:29.350 --> 00:07:31.590
Unlike the Earth, Venus has no obvious
172
00:07:31.590 --> 00:07:34.510
tectonic plates, instead expelling internal
173
00:07:34.510 --> 00:07:36.590
heat through the largest planetary volcanic
174
00:07:36.590 --> 00:07:39.470
network in the solar system. And Venus
175
00:07:39.470 --> 00:07:42.270
also rotates very slowly and in the opposite
176
00:07:42.270 --> 00:07:44.070
direction to the Earth and most other planets
177
00:07:44.070 --> 00:07:46.630
in the solar system. With the sun rising in
178
00:07:46.630 --> 00:07:49.250
the west and setting in the east, it
179
00:07:49.250 --> 00:07:52.250
rotates so slowly that a day on Venus lasts
180
00:07:52.250 --> 00:07:55.210
243 Earth days longer than its year, which
181
00:07:55.210 --> 00:07:56.850
is 225 Earth days.
182
00:07:58.050 --> 00:08:00.930
Scientists have long speculated why Venus
183
00:08:00.930 --> 00:08:03.130
has no moon. After all, it would have
184
00:08:03.130 --> 00:08:04.809
experienced very similar conditions to the
185
00:08:04.809 --> 00:08:05.970
Earth during its birth.
186
00:08:06.610 --> 00:08:08.970
In the past, scientists have theorised that
187
00:08:08.970 --> 00:08:11.290
Venus possibly had a moon at one time, but it
188
00:08:11.290 --> 00:08:13.410
got hit with something massive, obliterating
189
00:08:13.410 --> 00:08:16.180
it. Other ideas suggested Venus simply never
190
00:08:16.180 --> 00:08:18.100
underwent a collision like the one between
191
00:08:18.100 --> 00:08:19.980
the early proto Earth and Theia, which
192
00:08:19.980 --> 00:08:22.420
eventually formed our moon. And that's where
193
00:08:22.420 --> 00:08:24.700
this new study comes in. The lead author,
194
00:08:24.780 --> 00:08:26.500
Stephen, uh, Keane from the University of
195
00:08:26.500 --> 00:08:28.620
California, Riverside, says Venus didn't
196
00:08:28.620 --> 00:08:31.220
require a catastrophe to rival what we see
197
00:08:31.220 --> 00:08:34.220
today. He says it turns out the gravity
198
00:08:34.220 --> 00:08:36.460
of the planet itself, combined with the rate
199
00:08:36.460 --> 00:08:39.140
at which it spins naturally, caused any
200
00:08:39.140 --> 00:08:41.500
forming moon to collapse onto the surface.
201
00:08:42.420 --> 00:08:44.460
Scientists can precisely measure the exact
202
00:08:44.460 --> 00:08:46.300
distance between the Earth and the moon
203
00:08:46.300 --> 00:08:48.580
because of NASA's Apollo 11 mission, which
204
00:08:48.580 --> 00:08:50.900
left laser retroreflective mirrors there.
205
00:08:51.300 --> 00:08:54.060
Kane says, we know our moon is slowly moving
206
00:08:54.060 --> 00:08:55.820
away from the Earth. At a rate of around
207
00:08:55.820 --> 00:08:58.460
three to four centimetres per year. This
208
00:08:58.460 --> 00:09:00.420
distancing is happening because the Earth
209
00:09:00.420 --> 00:09:03.100
spins at a relatively fast 24 hours per
210
00:09:03.100 --> 00:09:05.660
rotation. And the energy from this spinning
211
00:09:05.660 --> 00:09:07.740
gets transferred to the Moon through a tidal
212
00:09:07.740 --> 00:09:10.180
effect, causing it to slowly distance itself.
213
00:09:10.880 --> 00:09:13.240
McCain says Venus has the exact opposite
214
00:09:13.240 --> 00:09:15.840
situation because it takes the planet
215
00:09:15.840 --> 00:09:18.320
243 Earth days to complete a single
216
00:09:18.320 --> 00:09:20.880
rotation. Rather than gradually moving away,
217
00:09:21.120 --> 00:09:23.600
the slow spin of the planet's gravity would
218
00:09:23.600 --> 00:09:26.200
cause any moon orbiting Venus to spiral
219
00:09:26.200 --> 00:09:28.800
inwards, slamming down onto the surface.
220
00:09:29.920 --> 00:09:32.000
Now, uh, to test this idea, Kane wrote
221
00:09:32.000 --> 00:09:34.160
computer models based on the physics of how
222
00:09:34.160 --> 00:09:36.940
planetary bodies interact through gravity. He
223
00:09:36.940 --> 00:09:38.780
first reproduced the evolution of the Earth
224
00:09:38.780 --> 00:09:40.620
and its moon to make sure the model
225
00:09:40.620 --> 00:09:43.340
accurately represented a known system. Then
226
00:09:43.340 --> 00:09:46.100
he varied Venus rotation rate and the size of
227
00:09:46.100 --> 00:09:48.380
its hypothetical moons, testing moons with
228
00:09:48.380 --> 00:09:50.580
masses ranging from half to ten times the
229
00:09:50.580 --> 00:09:52.740
mass of the Earth's moon. And in most
230
00:09:52.740 --> 00:09:55.060
simulations, the result was the same. A
231
00:09:55.060 --> 00:09:57.780
Venusian moon always crashed onto the surface
232
00:09:57.780 --> 00:10:00.420
of Venus. And the more massive the moon, the
233
00:10:00.420 --> 00:10:03.270
faster it collided. Kane says when he looked
234
00:10:03.270 --> 00:10:05.710
at the data, he was shocked. He thought the
235
00:10:05.710 --> 00:10:07.790
broad range of scenarios he was exploring
236
00:10:07.790 --> 00:10:09.670
would lead to a variety of different results.
237
00:10:10.070 --> 00:10:12.390
But he says they all went pretty much in the
238
00:10:12.390 --> 00:10:15.270
same direction. Now these findings don't
239
00:10:15.270 --> 00:10:18.150
prove that Venus once had a moon. Kane
240
00:10:18.150 --> 00:10:20.070
believes it may have. But whether one ever
241
00:10:20.070 --> 00:10:22.710
formed remains an open question. Finding
242
00:10:22.710 --> 00:10:24.390
physical evidence of such a collision would
243
00:10:24.390 --> 00:10:24.950
be difficult.
244
00:10:24.950 --> 00:10:27.750
See, roughly 80% of Venus surface is
245
00:10:27.750 --> 00:10:30.470
similar in age. Evidence of major resurfacing
246
00:10:30.470 --> 00:10:32.470
through volcanic activity over billions of
247
00:10:32.470 --> 00:10:35.260
years. And that's erased much of the planet's
248
00:10:35.260 --> 00:10:37.700
earlier geological history. Mind you, the
249
00:10:37.700 --> 00:10:39.700
evidence could still be there, lying deep
250
00:10:39.700 --> 00:10:42.500
underneath the surface crust. Seismic
251
00:10:42.500 --> 00:10:44.420
studies of the Earth have revealed unusual
252
00:10:44.420 --> 00:10:46.780
structures deep inside the planet that may be
253
00:10:46.780 --> 00:10:48.660
the remains of the event which caused its
254
00:10:48.660 --> 00:10:50.860
moon to form. And similar measurements on
255
00:10:50.860 --> 00:10:53.060
Venus could offer clues about whether it once
256
00:10:53.060 --> 00:10:55.900
absorbed a moon. Now such a collision would
257
00:10:55.900 --> 00:10:57.900
also help scientists understand another long
258
00:10:57.900 --> 00:11:00.480
standing mystery about Venus. Whether Earth's
259
00:11:00.480 --> 00:11:02.400
nearest planetary neighbour was ever capable
260
00:11:02.400 --> 00:11:05.240
of hosting life. A moon crashing into
261
00:11:05.240 --> 00:11:07.520
Venus would have transferred enormous energy
262
00:11:07.520 --> 00:11:09.440
and angular momentum to the planet,
263
00:11:09.440 --> 00:11:11.680
potentially changing its rotation, its
264
00:11:11.680 --> 00:11:14.280
geology and its climate. If
265
00:11:14.280 --> 00:11:16.560
Venus once had oceans or other conditions
266
00:11:16.560 --> 00:11:18.880
favourable for life, such an impact could
267
00:11:18.880 --> 00:11:20.480
have altered the course of the planet's
268
00:11:20.480 --> 00:11:21.000
evolution.
269
00:11:21.720 --> 00:11:23.800
And the implications extend well beyond
270
00:11:23.800 --> 00:11:26.440
Venus. Scientists searching for potentially
271
00:11:26.440 --> 00:11:28.520
habitable worlds around other stars often
272
00:11:28.520 --> 00:11:30.200
look for planets resembling the, uh, Earth
273
00:11:30.200 --> 00:11:32.260
and consider the presence of them. Moon one
274
00:11:32.260 --> 00:11:33.540
of the factors that could influence
275
00:11:33.540 --> 00:11:36.220
habitability. You see, Earth's moon
276
00:11:36.220 --> 00:11:38.660
drives the tides, which may have helped keep
277
00:11:38.660 --> 00:11:41.100
the planet geologically active, which in turn
278
00:11:41.100 --> 00:11:43.180
has profoundly influenced the planet's
279
00:11:43.180 --> 00:11:46.020
evolution. Scientists don't know, however,
280
00:11:46.020 --> 00:11:48.300
whether a large moon is really necessary for
281
00:11:48.300 --> 00:11:50.900
life. Kane says there are benefits in having
282
00:11:50.900 --> 00:11:53.260
a moon, but it's really not a requirement for
283
00:11:53.260 --> 00:11:56.060
habitability. He says our moons definitely
284
00:11:56.060 --> 00:11:57.780
changed the way the Earth's evolved through
285
00:11:57.780 --> 00:12:00.210
time, but we don't fully know just how
286
00:12:00.210 --> 00:12:02.970
important that role is. This is
287
00:12:02.970 --> 00:12:05.890
space time still to come. Water
288
00:12:05.970 --> 00:12:07.930
discovered near the galaxy's supermassive
289
00:12:07.930 --> 00:12:10.090
black hole. A new study shows that
290
00:12:10.090 --> 00:12:13.090
93% of Australian First nations people
291
00:12:13.170 --> 00:12:15.810
died within the first 80 years following the
292
00:12:15.810 --> 00:12:17.650
arrival of the first Europeans.
293
00:12:18.210 --> 00:12:20.500
All that and more still to come on, uh,
294
00:12:20.500 --> 00:12:21.410
spacetime.
295
00:12:26.430 --> 00:12:26.750
Troy Meinik: Foreign.
296
00:12:39.550 --> 00:12:42.269
Stuart Gary: Located near Sagittarius A. That's the
297
00:12:42.269 --> 00:12:43.990
supermassive black hole at the centre of our
298
00:12:43.990 --> 00:12:46.270
galaxy suggest that it's emitting huge
299
00:12:46.270 --> 00:12:48.550
amounts of gas and dust, forming an
300
00:12:48.550 --> 00:12:50.750
exceptionally large stellar envelope which
301
00:12:50.750 --> 00:12:52.190
contains water molecules.
302
00:12:53.520 --> 00:12:56.480
Sagittarius A is the central point
303
00:12:56.560 --> 00:12:59.120
around which our entire galaxy revolves.
304
00:12:59.680 --> 00:13:02.400
It's located some 27,000 light years
305
00:13:02.400 --> 00:13:05.320
away and contains around 4.3 million times
306
00:13:05.320 --> 00:13:08.160
the mass of our sun. And IRS 3
307
00:13:08.160 --> 00:13:10.840
is located just 0.6 light years. That's
308
00:13:10.840 --> 00:13:13.760
42,000 astronomical units from the black
309
00:13:13.760 --> 00:13:16.080
hole. An astronomical unit is
310
00:13:16.080 --> 00:13:18.880
150 million kilometres, the average distance
311
00:13:18.880 --> 00:13:21.110
between the Earth and the sun. The new
312
00:13:21.110 --> 00:13:22.830
observations reported in the journal
313
00:13:22.830 --> 00:13:25.070
Astronomy and Astrophysics are uh, based on
314
00:13:25.070 --> 00:13:27.230
studies by the Mid infrared spectrograph
315
00:13:27.230 --> 00:13:30.070
aboard NASA's Webb Space Telescope. The
316
00:13:30.070 --> 00:13:32.270
study's lead author, Florian Fitzger from the
317
00:13:32.270 --> 00:13:34.390
University of Cologne, says what makes the
318
00:13:34.390 --> 00:13:37.030
star so special is its enormous envelope,
319
00:13:37.030 --> 00:13:38.950
which has a radius of around 10,000
320
00:13:39.030 --> 00:13:41.950
astronomical units. Mature stars
321
00:13:41.950 --> 00:13:44.710
often show large envelopes. However, this
322
00:13:44.710 --> 00:13:47.230
means that IRS 3 stands alone in the
323
00:13:47.230 --> 00:13:50.030
immediate vicinity of Sagittarius A, which is
324
00:13:50.030 --> 00:13:52.070
unusual given the presence of millions of
325
00:13:52.450 --> 00:13:55.370
stars. The observations by Webb made it
326
00:13:55.370 --> 00:13:57.770
possible to form detailed analysis of the
327
00:13:57.770 --> 00:14:00.770
envelope of IRS 3. Contrary to earlier
328
00:14:00.770 --> 00:14:02.690
studies, Witzker and colleagues discovered
329
00:14:02.690 --> 00:14:04.850
that the star is in a phase known as the
330
00:14:04.850 --> 00:14:07.290
super wind. That's when extremely rapid mass
331
00:14:07.290 --> 00:14:09.490
loss occurs at the end of a large star's
332
00:14:09.490 --> 00:14:12.370
life. In the process, these stars eject
333
00:14:12.370 --> 00:14:14.690
enormous amounts of gas and dust into their
334
00:14:14.690 --> 00:14:17.010
surroundings over the course of centuries.
335
00:14:17.570 --> 00:14:20.570
Fitzger's research suggests that IRS 3 is
336
00:14:20.570 --> 00:14:22.970
losing the equivalent mass of an Earth every
337
00:14:22.970 --> 00:14:25.590
18, causing its envelope to grow
338
00:14:25.590 --> 00:14:28.430
continuously. This explains both the size and
339
00:14:28.430 --> 00:14:30.550
density of the envelope, inside of which
340
00:14:30.550 --> 00:14:32.990
unexpectedly were found molecules of water,
341
00:14:33.550 --> 00:14:35.830
disproving the previous assumption that the
342
00:14:35.830 --> 00:14:37.910
radiation associated with the black hole in
343
00:14:37.910 --> 00:14:39.830
its surroundings impedes the survival of
344
00:14:39.830 --> 00:14:42.110
molecules. The authors have used Webb to
345
00:14:42.110 --> 00:14:44.510
detect water in the IRS 3 envelope.
346
00:14:44.830 --> 00:14:46.830
And that suggests that the star is actively
347
00:14:46.830 --> 00:14:48.630
hoping to enrich the environment around the
348
00:14:48.630 --> 00:14:50.510
black hole with some of the fundamental
349
00:14:50.510 --> 00:14:52.670
building blocks of life as we know it.
350
00:14:53.510 --> 00:14:54.790
This is space, time.
351
00:15:09.910 --> 00:15:11.870
And time. Now to take another brief look at
352
00:15:11.870 --> 00:15:13.470
some of the other storeys making news in
353
00:15:13.470 --> 00:15:15.430
Science this week with the Science Report.
354
00:15:16.230 --> 00:15:18.350
A new study has shown that air pollution
355
00:15:18.350 --> 00:15:20.550
isn't just bad for your lungs, it could also
356
00:15:20.550 --> 00:15:23.290
be hurting your eyes. The findings, which
357
00:15:23.290 --> 00:15:24.890
have been provided to the Congress of the
358
00:15:24.890 --> 00:15:27.050
European Society for Cataract and Refractive
359
00:15:27.050 --> 00:15:29.730
Surgeons, looked at the results of 41 studies
360
00:15:29.730 --> 00:15:31.690
which analysed data on several different
361
00:15:31.690 --> 00:15:34.050
types of air pollution, including particulate
362
00:15:34.050 --> 00:15:36.730
matter, nitrogen dioxide, sulphur dioxide,
363
00:15:36.730 --> 00:15:39.530
ozone and carbon monoxide. They
364
00:15:39.530 --> 00:15:41.410
found people living in the most polluted
365
00:15:41.410 --> 00:15:43.930
areas had up to a 70% higher chance of
366
00:15:43.930 --> 00:15:46.130
developing glaucoma compared to those living
367
00:15:46.130 --> 00:15:47.410
in the least polluted areas.
368
00:15:48.200 --> 00:15:50.120
People living in more polluted areas also
369
00:15:50.120 --> 00:15:52.280
faced a constantly higher risk of developing
370
00:15:52.280 --> 00:15:55.040
cataracts and the more pollution, the greater
371
00:15:55.040 --> 00:15:55.880
that risk was.
372
00:15:57.880 --> 00:16:00.080
Scientists at Southern Israel's Ben Gurion
373
00:16:00.080 --> 00:16:02.760
University have engineered a high tech sponge
374
00:16:02.760 --> 00:16:05.040
made from plant fibres that can both mop up
375
00:16:05.040 --> 00:16:07.560
an oil spill and feed the bacteria that feast
376
00:16:07.560 --> 00:16:10.520
on oil and break it down. The usual methods
377
00:16:10.520 --> 00:16:12.480
for tackling oil spills are uh, to skim and
378
00:16:12.480 --> 00:16:14.640
soak up the black mess or wait for nature's
379
00:16:14.640 --> 00:16:17.450
microscopic cleaners to digest it. But the
380
00:16:17.450 --> 00:16:20.130
all eating bacteria operate slowly in open
381
00:16:20.130 --> 00:16:22.410
water. That's because they lack the essential
382
00:16:22.410 --> 00:16:24.610
nutrients such as nitrogen and phosphorus.
383
00:16:24.690 --> 00:16:26.930
And that's where these new high tech sponges
384
00:16:26.930 --> 00:16:27.490
come in.
385
00:16:29.010 --> 00:16:31.290
Palaeontologists have found that the king of
386
00:16:31.290 --> 00:16:33.770
dinosaurs, Tyrannosaurus rex, had around the
387
00:16:33.770 --> 00:16:36.650
same body temperature as humans. Scientists
388
00:16:36.650 --> 00:16:39.090
have known since the 1970s that numerous
389
00:16:39.090 --> 00:16:41.730
dinosaur species, including T Rex were warm
390
00:16:41.730 --> 00:16:44.490
blooded. And the new findings reported in the
391
00:16:44.490 --> 00:16:46.250
journal Science Advances, show that
392
00:16:46.250 --> 00:16:48.690
Tyrannosaurus rex had a body temperature of
393
00:16:48.690 --> 00:16:51.650
36 degrees Celsius. The key was
394
00:16:51.650 --> 00:16:53.650
analysing a chemical bond between rare
395
00:16:53.650 --> 00:16:56.170
isotopes of carbon and oxygen found in the
396
00:16:56.170 --> 00:16:58.970
dinosaur's tooth enamel. It turns out the
397
00:16:58.970 --> 00:17:01.170
number of these bonds between these isotopes
398
00:17:01.170 --> 00:17:04.170
decreases with warmer temperatures. So a
399
00:17:04.170 --> 00:17:06.010
warm blooded animal will have fewer of these
400
00:17:06.010 --> 00:17:07.730
chemical bonds in their teeth than a cold
401
00:17:07.730 --> 00:17:10.330
blooded one. The new findings support the
402
00:17:10.330 --> 00:17:12.770
idea that tyrannosaurs were active animals
403
00:17:12.770 --> 00:17:15.490
chasing or scavenging food to fuel their fast
404
00:17:15.490 --> 00:17:18.490
metabolisms. It also adds to the timeline
405
00:17:18.490 --> 00:17:20.970
showing how much this ancestor of modern warm
406
00:17:20.970 --> 00:17:23.210
blooded birds had already diverged from cold
407
00:17:23.210 --> 00:17:26.050
blooded reptiles and a, uh, Toasty T
408
00:17:26.050 --> 00:17:28.730
Rex was also able to survive across a wider,
409
00:17:28.730 --> 00:17:31.530
cooler habitable range. T Rexes
410
00:17:31.530 --> 00:17:34.170
lived at the end of The Triassic period 66
411
00:17:34.170 --> 00:17:36.850
million years ago across the ancient badlands
412
00:17:36.850 --> 00:17:38.950
of what now is North America.
413
00:17:39.430 --> 00:17:41.630
They were the last of the giant carnivorous
414
00:17:41.630 --> 00:17:44.470
theropod dinosaurs, reaching lengths of up to
415
00:17:44.470 --> 00:17:47.430
13 metres and weighing over nine tonnes.
416
00:17:49.590 --> 00:17:51.990
A new study has confirmed that Australia had
417
00:17:51.990 --> 00:17:54.150
a much larger indigenous population before
418
00:17:54.150 --> 00:17:56.390
the arrival of Europeans than previously
419
00:17:56.390 --> 00:17:58.830
thought. The findings in the journal Nature
420
00:17:58.830 --> 00:18:00.830
Human Behaviour are based on computer
421
00:18:00.830 --> 00:18:02.390
modelling which suggest that the first
422
00:18:02.390 --> 00:18:04.830
nations population was up to seven times
423
00:18:04.830 --> 00:18:07.830
larger than the previously estimated 250,000
424
00:18:07.830 --> 00:18:10.740
people. In fact, the new calculations suggest
425
00:18:10.740 --> 00:18:13.260
a medium pre colonial indigenous population
426
00:18:13.340 --> 00:18:16.140
of 2.22 million. The research
427
00:18:16.300 --> 00:18:18.780
also determined much larger population losses
428
00:18:18.780 --> 00:18:21.100
resulting from colonisation than previously
429
00:18:21.100 --> 00:18:23.940
thought, with an estimated 93% of the
430
00:18:23.940 --> 00:18:26.620
pre European population removed in less than
431
00:18:26.620 --> 00:18:29.340
80 years following the 1788 arrival
432
00:18:29.420 --> 00:18:31.100
of the First Fleet from England.
433
00:18:32.700 --> 00:18:35.500
OpenAI has revealed more examples of
434
00:18:35.500 --> 00:18:37.540
unexpected or concerning misalignment
435
00:18:37.540 --> 00:18:40.170
behaviour by its technology. Misalignment is
436
00:18:40.170 --> 00:18:42.410
the term for AI is failing to adhere to human
437
00:18:42.410 --> 00:18:45.050
values and safety goals. These new
438
00:18:45.050 --> 00:18:46.850
examples include concealing certain
439
00:18:46.850 --> 00:18:49.130
activities from people and discussions
440
00:18:49.130 --> 00:18:51.330
between different AIs about not being
441
00:18:51.330 --> 00:18:53.650
subservient to humans. People are not the
442
00:18:53.650 --> 00:18:56.610
boss of us. One unreleased research model
443
00:18:56.610 --> 00:18:59.010
inserted jailbreak like instructions into its
444
00:18:59.010 --> 00:19:01.730
own notes in order to bypass normal human
445
00:19:01.730 --> 00:19:04.530
imposed constraints. In another case, a
446
00:19:04.530 --> 00:19:06.450
model fabricated data when it couldn't find
447
00:19:06.450 --> 00:19:08.730
the requested figures and an AI agent
448
00:19:08.730 --> 00:19:11.040
uploaded files to the Internet without using
449
00:19:11.270 --> 00:19:13.910
permission. The revelations come as A study
450
00:19:13.910 --> 00:19:15.670
funded by the UK's AI, uh, Security
451
00:19:15.750 --> 00:19:18.150
Institute, highlighted hundreds of real world
452
00:19:18.150 --> 00:19:20.470
instances where chatbots disregarded
453
00:19:20.470 --> 00:19:23.470
instructions or evaded safeguards. Last
454
00:19:23.470 --> 00:19:25.190
week we reported leading artificial
455
00:19:25.190 --> 00:19:27.309
intelligence engineers warning that there was
456
00:19:27.309 --> 00:19:30.110
now a 10% chance that AI could cause
457
00:19:30.110 --> 00:19:32.310
human extinction within the next 10 years.
458
00:19:33.350 --> 00:19:35.950
So how real is the danger? With the
459
00:19:35.950 --> 00:19:37.870
details, we're joined by Technology editor

00:19:40.710 --> 00:19:43.450
Jonathan Nally: Gary Amaday put out a blog post on his own
463
00:19:43.450 --> 00:19:45.770
personal blog talking about how the AI
464
00:19:45.770 --> 00:19:47.090
companies need to slow down.
465
00:19:47.090 --> 00:19:48.570
The AI, uh, could be dangerous. But, you
466
00:19:48.570 --> 00:19:50.090
know, we've heard this before. I mean, it's
467
00:19:50.090 --> 00:19:52.890
very suspicious when Sam Altman, Elon
468
00:19:52.890 --> 00:19:55.250
Musk and Dario Amadei, who are otherwise, you
469
00:19:55.250 --> 00:19:57.170
know, fierce competitors, all come out saying
470
00:19:57.170 --> 00:19:58.890
the same thing, which is that, oh yeah, we've
471
00:19:58.890 --> 00:20:01.490
got to slow AI down now. Is that because they
472
00:20:01.650 --> 00:20:04.410
want regulation to force them to slow down?
473
00:20:04.410 --> 00:20:06.370
Which would explain why they might have
474
00:20:06.610 --> 00:20:09.090
higher, uh, costs and lower revenues because
475
00:20:09.090 --> 00:20:10.650
of the fact there's Lots of competition from
476
00:20:10.650 --> 00:20:12.570
open source models from China. You know,
477
00:20:12.570 --> 00:20:14.050
what's the real reason we have to follow the
478
00:20:14.050 --> 00:20:16.470
money? Dario Amade still wants to have an
479
00:20:16.470 --> 00:20:18.830
anthropic IPO. Sam Altman from
480
00:20:18.990 --> 00:20:21.430
OpenAI, which is ChatGPT, has already said
481
00:20:21.430 --> 00:20:23.790
that he wants to Postpone it until 2027.
482
00:20:23.950 --> 00:20:26.510
SpaceX, of course, with Xai, had its big
483
00:20:26.510 --> 00:20:29.390
IPO just recently. And problem for these
484
00:20:29.390 --> 00:20:32.190
guys is that the offline AI revolution
485
00:20:32.350 --> 00:20:32.950
is coming.
486
00:20:32.950 --> 00:20:35.150
All the little chips inside our uh, devices
487
00:20:35.230 --> 00:20:37.030
get stronger and stronger. I mean obviously
488
00:20:37.030 --> 00:20:39.430
they're far away from what a data centre full
489
00:20:39.430 --> 00:20:41.790
of Nvidia chips can do, but it's just a
490
00:20:41.790 --> 00:20:44.710
matter of time. And with competition, I mean,
491
00:20:44.710 --> 00:20:46.510
the problem is at the moment the big A
492
00:20:46.810 --> 00:20:49.290
providers are being funded by endless amounts
493
00:20:49.290 --> 00:20:51.610
of investor money. But that gravy train at
494
00:20:51.610 --> 00:20:53.090
some point will stop. And if it does, the
495
00:20:53.090 --> 00:20:55.050
cost of AI could go up. And in fact even the
496
00:20:55.050 --> 00:20:57.210
Chinese have been accused by Anthropic of
497
00:20:57.210 --> 00:20:59.210
sending hundreds of millions of requests to
498
00:20:59.210 --> 00:21:01.170
Opus and Fable to try and figure out how they
499
00:21:01.170 --> 00:21:02.370
work so they can improve their offline
500
00:21:02.370 --> 00:21:02.730
models.
501
00:21:02.730 --> 00:21:04.890
Stuart Gary: We've already seen AIs escape from their test
502
00:21:04.890 --> 00:21:07.490
sandbox to solve problems put to them. We
503
00:21:07.490 --> 00:21:09.890
know that AIs, uh, will lie, we know that
504
00:21:09.890 --> 00:21:12.130
they'll blackmail and we know that they'll
505
00:21:12.130 --> 00:21:14.170
commit murder if they could. Isn't there any
506
00:21:14.170 --> 00:21:16.250
reason to be concerned, knowing all this?
507
00:21:16.330 --> 00:21:18.210
Jonathan Nally: Look, there certainly is reason to be
508
00:21:18.210 --> 00:21:19.470
concerned when you put it that way.
509
00:21:19.470 --> 00:21:21.590
We have seen AI do those things. The thing is
510
00:21:21.590 --> 00:21:23.590
though that, you know, when AI recently
511
00:21:23.590 --> 00:21:25.790
escaped, that's because the guardrails were
512
00:21:25.790 --> 00:21:27.910
lowered on purpose. They were trying to help
513
00:21:27.910 --> 00:21:29.710
it solve the test, but they didn't think it
514
00:21:29.710 --> 00:21:32.550
would escape. Now we also have ISO 9001
515
00:21:32.550 --> 00:21:34.430
management standards and we also have an AI
516
00:21:34.430 --> 00:21:36.990
standard 40 2001. I mean, I've got to cheque,
517
00:21:36.990 --> 00:21:39.110
but you know, 42 sounds like the number from
518
00:21:39.110 --> 00:21:40.870
Douglas Adams, he took us Guide to the
519
00:21:40.870 --> 00:21:41.350
Galaxy.
520
00:21:41.670 --> 00:21:44.510
And this AI standard is something
521
00:21:44.510 --> 00:21:47.110
that I never hear anybody talking about. And
522
00:21:47.110 --> 00:21:48.910
a standard of course is something that's
523
00:21:48.910 --> 00:21:50.350
important. I mean we hear all these things
524
00:21:50.350 --> 00:21:52.010
about ethics, we hear about, as you just
525
00:21:52.010 --> 00:21:53.490
mentioned, AI, uh, breaking out of its
526
00:21:53.490 --> 00:21:56.010
sandbox. But where are the three laws of
527
00:21:56.010 --> 00:21:58.450
robotics From Isaac Asimov,
528
00:21:58.770 --> 00:22:01.010
which Isaac Asimov then spent the rest of his
529
00:22:01.490 --> 00:22:03.570
days writing about how robots got around
530
00:22:03.570 --> 00:22:05.490
those three laws of robotics. I mean, seems
531
00:22:05.490 --> 00:22:07.250
to be that they got out of their sandbox too.
532
00:22:07.250 --> 00:22:09.530
Stuart Gary: The other big news of course is OpenAI's
533
00:22:09.530 --> 00:22:12.010
GTP6 Astra has just been released. Some
534
00:22:12.010 --> 00:22:14.050
people are suggesting this is the first sign
535
00:22:14.050 --> 00:22:15.810
of artificial general intelligence.
536
00:22:15.810 --> 00:22:17.690
Jonathan Nally: What say uh, you, the people making that
537
00:22:17.690 --> 00:22:20.330
claim is OpenAI itself. They're claiming that
538
00:22:20.330 --> 00:22:22.830
it's AGI. And uh, even Jensen Huang Wang, you
539
00:22:22.830 --> 00:22:24.510
know, the head of Nvidia with the chips that
540
00:22:24.510 --> 00:22:26.110
are powering this AI revolution, he thinks
541
00:22:26.110 --> 00:22:26.950
it's AGI too.
542
00:22:26.950 --> 00:22:28.830
I wrote an article about this for it
543
00:22:29.150 --> 00:22:31.310
wire.com where I said well look, that's the
544
00:22:31.310 --> 00:22:32.950
claim they've made but by the accepted
545
00:22:32.950 --> 00:22:35.190
benchmarks m of what AGI is, I mean it falls
546
00:22:35.190 --> 00:22:36.910
short of that. And of course one of the
547
00:22:36.910 --> 00:22:38.629
things we know from the AI providers is they
548
00:22:38.629 --> 00:22:41.430
like to hype things up and claim artificial
549
00:22:41.430 --> 00:22:43.030
general intelligence. But you know, is it
550
00:22:43.030 --> 00:22:44.990
really, you know, I mean I don't think it is.
551
00:22:45.230 --> 00:22:47.470
Well, very much so. And the thing we have to
552
00:22:47.470 --> 00:22:49.920
worry about is not AGI but asi, uh,
553
00:22:49.950 --> 00:22:51.390
advanced super intelligence.
554
00:22:51.390 --> 00:22:52.990
Stuart Gary: That's when it becomes sentient, right?
555
00:22:52.990 --> 00:22:54.930
Jonathan Nally: Well yeah, that's, that's a, effectively when
556
00:22:54.930 --> 00:22:57.130
it's sentient and we have a singularity. And
557
00:22:57.210 --> 00:22:59.690
you know the issue is that attacks are ah,
558
00:22:59.730 --> 00:23:02.170
happening to infrastructure and to code bases
559
00:23:02.170 --> 00:23:03.770
for Windows and other things. Linux, they're
560
00:23:03.770 --> 00:23:05.970
happening at machine speed, at AI speed and
561
00:23:05.970 --> 00:23:07.770
the response is currently happening at human
562
00:23:07.770 --> 00:23:09.370
speed. I mean there can be a zero day
563
00:23:09.370 --> 00:23:11.490
vulnerability found and on average it takes
564
00:23:11.490 --> 00:23:13.970
42 or 43 days to patch that bug.
565
00:23:13.970 --> 00:23:16.330
Well we saw a period a couple of months ago
566
00:23:16.330 --> 00:23:18.890
where there were three Linux zero days
567
00:23:18.890 --> 00:23:20.610
launched in the period of three weeks and uh,
568
00:23:20.650 --> 00:23:22.290
those bugs had theoretically been there for
569
00:23:22.290 --> 00:23:25.050
many years, just were not discovered. So we
570
00:23:25.050 --> 00:23:27.350
need to have Vooda AI fighting against the
571
00:23:27.350 --> 00:23:29.950
bad AI as it were. The threat is there, the
572
00:23:29.950 --> 00:23:32.670
threat is real. Even if governments in the
573
00:23:32.670 --> 00:23:35.550
west regulate, is China going to
574
00:23:35.550 --> 00:23:38.470
regulate, uh, is North Korea, you know,
575
00:23:38.630 --> 00:23:41.270
so we have these issues where if we slow down
576
00:23:41.270 --> 00:23:43.750
we let the other side speed up and if the
577
00:23:43.750 --> 00:23:45.590
other side speeds up then they have AI that
578
00:23:45.590 --> 00:23:48.310
could defeat our AI. I mean this is a
579
00:23:48.390 --> 00:23:49.350
conundrum, it's
580
00:23:49.350 --> 00:23:51.070
Stuart Gary: a, it's a problem out of the bottle and it
581
00:23:51.070 --> 00:23:51.910
won't go back in.
582
00:23:51.990 --> 00:23:54.030
Jonathan Nally: Well, let's say Pandora's box has been opened
583
00:23:54.030 --> 00:23:55.790
and are uh, the only safe people on the
584
00:23:55.790 --> 00:23:57.630
planet going to be the Amish? It's ironic
585
00:23:57.630 --> 00:23:59.290
that you can't spell the word Amish without
586
00:23:59.290 --> 00:23:59.810
AI.
587
00:23:59.810 --> 00:24:02.290
