7
00:00:26.039 --> 00:00:39.000
Welcome to Space Time with Stuart Gary.
8
00:00:45.240 --> 00:00:48.799
A new study suggests that ancient black holes from before
9
00:00:48.840 --> 00:00:52.920
the Big Bang may be shaping our universe. The idea
10
00:00:53.280 --> 00:00:56.840
is that the cosmos goes through eternal, never ending cycles
11
00:00:56.920 --> 00:00:59.799
of expanding up from the Big Bang and then eventually
12
00:01:00.000 --> 00:01:03.560
collapsing again into a big crunch, which then triggers another
13
00:01:03.600 --> 00:01:06.319
Big Bang, followed by another big crunch, and so on.
14
00:01:07.040 --> 00:01:10.519
The key to supporting this hypothesis would be black holes
15
00:01:10.560 --> 00:01:13.560
that form before the Big Bang, which could still exist
16
00:01:13.640 --> 00:01:18.560
today as cosmic fossils. The study behind the hypothesis, reported
17
00:01:18.599 --> 00:01:21.599
in the journal Physical Review D, suggest that these relic
18
00:01:21.680 --> 00:01:26.719
black holes could potentially help explain that mysterious invisible substance
19
00:01:26.760 --> 00:01:30.079
known as dark matter, which shapes galaxies and the large
20
00:01:30.120 --> 00:01:34.480
scale structure of our universe. The Studies. Lead author Enrico
21
00:01:34.560 --> 00:01:38.359
Goes Tangagar from Portsmouth University says the universe may not
22
00:01:38.439 --> 00:01:41.159
have a beginning with a single explosive event, which we
23
00:01:41.239 --> 00:01:44.719
these days called the Big Bang, but instead may align
24
00:01:44.799 --> 00:01:47.400
with more of a cosmic bounce model, in which the
25
00:01:47.480 --> 00:01:51.319
universe emerged from an earlier contraction and left behind relic
26
00:01:51.359 --> 00:01:55.079
black holes that have survived that contraction and expansion right
27
00:01:55.159 --> 00:01:59.400
through to the present day as cosmic fossils. Now. If correct,
28
00:01:59.599 --> 00:02:04.560
these amordial objects could help explain long standing mysteries in cosmology,
29
00:02:04.719 --> 00:02:07.640
including the nature of dark matter and the process which
30
00:02:07.680 --> 00:02:11.680
ceeded the formation of galaxies. Iss Tangage says that for
31
00:02:11.759 --> 00:02:14.960
almost a century now, cosmologists have traced the history of
32
00:02:15.000 --> 00:02:17.960
the universe back to a single dramatic event, which we
33
00:02:18.039 --> 00:02:21.719
call the Big Bang. In this standard model of cosmology,
34
00:02:21.919 --> 00:02:25.439
space and time emerge from an extremely hot, dense state
35
00:02:25.599 --> 00:02:28.639
around thirteen point eight billion years ago, followed by billions
36
00:02:28.680 --> 00:02:33.360
of years of cosmic expansion and galaxy formation. He points out,
37
00:02:33.400 --> 00:02:37.039
this model has been remarkably successful. It explains the cosmic
38
00:02:37.080 --> 00:02:40.759
microwave background radiation, the faint heat left over from the
39
00:02:40.759 --> 00:02:43.960
early universe, now down to two point seven degrees above
40
00:02:44.000 --> 00:02:48.240
absolute zero, and it also predicts how galaxies are distributed
41
00:02:48.280 --> 00:02:52.080
across the vast cosmic web. But some of the deepest
42
00:02:52.199 --> 00:02:56.639
mysteries in physics remain unresolved. For example, we still don't
43
00:02:56.680 --> 00:02:59.520
know what triggered the Big Bang in the first place, or,
44
00:02:59.560 --> 00:03:02.520
for that matter, what happened before it. If anything, why
45
00:03:02.560 --> 00:03:06.080
the universe began in such a special state, what caused
46
00:03:06.080 --> 00:03:09.599
the brief sudden burst of rapid expansion known as cosmic inflation,
47
00:03:09.879 --> 00:03:12.080
needed to explain why the universe looks the way it
48
00:03:12.120 --> 00:03:16.680
does today, and what this invisible mysterious substance dark matter
49
00:03:16.879 --> 00:03:20.879
really is, a substance which outweighs ordinary matter by about
50
00:03:20.919 --> 00:03:25.199
five to one, and so this new hypothesis explores the
51
00:03:25.240 --> 00:03:29.479
possibility that could connect several of these puzzles. The universe
52
00:03:29.560 --> 00:03:32.319
may not have begun with a single Big Bang, but
53
00:03:32.520 --> 00:03:36.840
instead emerged from a cosmic bounce mimicking inflation, with some
54
00:03:36.919 --> 00:03:39.919
of the oldest objects in the universe potentially serving as
55
00:03:40.000 --> 00:03:44.400
relics for what happened before. It means some black holes
56
00:03:44.520 --> 00:03:47.960
may well have formed during the earlier cosmic phase before
57
00:03:48.000 --> 00:03:51.319
the Big Bang and survived the bounce, leaving behind relic
58
00:03:51.360 --> 00:03:54.879
objects that may still influence the structure of galaxies billions
59
00:03:54.919 --> 00:03:58.360
of years later. Others could have formed shortly after the
60
00:03:58.400 --> 00:04:02.039
bounce from amplified density fluctuations were Matter in the early
61
00:04:02.159 --> 00:04:06.759
universe was unevenly distributed in stronger, more pronounced clumps than usual,
62
00:04:07.439 --> 00:04:10.719
and these enhanced clumps of matter would collapse more easily
63
00:04:10.800 --> 00:04:13.840
under their own gravity, making it more likely for large
64
00:04:13.840 --> 00:04:17.680
cosmic structures and black holes to form early on. In
65
00:04:17.759 --> 00:04:21.600
Albert Einstein's theory of general relativity, the Big Bang corresponds
66
00:04:21.639 --> 00:04:24.759
with what's known as the singularity, a point where density
67
00:04:24.800 --> 00:04:28.639
becomes infinite, volume becomes zero, and the laws of physics
68
00:04:28.680 --> 00:04:32.240
as we understand them break down, and of course, that
69
00:04:32.360 --> 00:04:35.720
also describes the singularity at the center of a black hole.
70
00:04:36.399 --> 00:04:39.399
Many physicists interpret this as a sign that our current
71
00:04:39.439 --> 00:04:43.240
description of the earliest moments of the universe is incomplete.
72
00:04:43.279 --> 00:04:45.759
A bounce, we call it the Big Bang, provides a
73
00:04:45.759 --> 00:04:49.160
way for the universe to transition from contraction to expansion
74
00:04:49.360 --> 00:04:53.439
without requiring new exotic physics, and the authors suggest this
75
00:04:53.600 --> 00:04:57.519
bounce could have arisen naturally through quantum physics. They say,
76
00:04:57.639 --> 00:05:01.639
at extreme densities, quantum effects yet a powerful pressure which
77
00:05:01.680 --> 00:05:05.399
prevents matter from being compressed indefinitely, a phenomenon that already
78
00:05:05.399 --> 00:05:09.120
stabilizes dense objects such as white dwarfs and neutron stars
79
00:05:09.160 --> 00:05:13.680
and reproduces the inflationary expansion phase in the new model,
80
00:05:13.839 --> 00:05:17.560
a similar effect could be occurring on cosmic scales. As
81
00:05:17.600 --> 00:05:21.680
the universe contracts. This quantum pressure could halt the collapse
82
00:05:21.920 --> 00:05:25.680
and trigger a rebound into expansion. And this bounce could
83
00:05:25.720 --> 00:05:29.560
explain two of the biggest mistress in cosmology. First, it
84
00:05:29.600 --> 00:05:32.519
may account for why the universe expanded so rapidly and
85
00:05:32.600 --> 00:05:35.800
evenly in all directions, and secondly, it could shed light
86
00:05:35.879 --> 00:05:38.839
on why the universe appears to be expanding at an
87
00:05:38.879 --> 00:05:42.160
ever accelerating rate, an effect currently attributed to a poor
88
00:05:42.240 --> 00:05:46.720
understanding of a mysterious force we call duck energy. One
89
00:05:46.800 --> 00:05:50.759
striking implication is that some structures formed during the collapse
90
00:05:50.759 --> 00:05:54.920
phase may have survived the bounce. The author's calculation suggests
91
00:05:54.959 --> 00:05:58.519
that compact objects larger than roughly ninety meters in size
92
00:05:58.560 --> 00:06:02.120
could pass through the transition and reappear in the expanding
93
00:06:02.240 --> 00:06:06.240
universe as fossils from before. Possible relics include things like
94
00:06:06.279 --> 00:06:11.879
gravitational waves, density, fluctuations and ancient black holes. These relic
95
00:06:11.920 --> 00:06:14.920
black holes could have explained dark matter, and if large
96
00:06:15.000 --> 00:06:17.560
numbers formed during the bounce, they might even make up
97
00:06:17.560 --> 00:06:20.759
a significant fraction, possibly even all of the dark matter
98
00:06:20.759 --> 00:06:24.560
in the universe today, and it doesn't end there. This
99
00:06:24.680 --> 00:06:27.560
idea may also have explained recent discoveries by the James
100
00:06:27.560 --> 00:06:31.639
Webspace Telescope, which has captured images of unexpectedly massive objects
101
00:06:31.680 --> 00:06:35.120
in the early universe nicknamed little red dots. The leading
102
00:06:35.199 --> 00:06:38.759
hypothesis to explain these little red dots are rapidly growing
103
00:06:38.800 --> 00:06:41.959
black holes in the early universe which are burning through
104
00:06:42.000 --> 00:06:46.439
the surrounding gas gas. Tangaga says, if massive black holes
105
00:06:46.480 --> 00:06:50.160
already existed immediately after the bounce, the early universe wouldn't
106
00:06:50.199 --> 00:06:53.399
need to start from scratch when't building the first galaxies.
107
00:06:54.519 --> 00:06:57.240
The theory also makes predictions that can be tested with
108
00:06:57.279 --> 00:07:00.560
future observations, and that's an important part of it science.
109
00:07:01.279 --> 00:07:05.319
Astronomers could search for really gravitational waves from previous cosmic
110
00:07:05.399 --> 00:07:09.399
faces or subtle patterns in the cosmic microwave background radiation,
111
00:07:09.680 --> 00:07:13.079
preserving a trace of the universe before the Big Bang.
112
00:07:13.839 --> 00:07:17.480
It's a fascinating insight and one which I'm sure will
113
00:07:17.480 --> 00:07:22.600
spark lots of debate. This is space time still to come,
114
00:07:22.920 --> 00:07:26.120
the bathtub bring hinting at an ancient Martian ocean, and
115
00:07:26.279 --> 00:07:29.600
a just reward for studying the stars. All that and
116
00:07:29.680 --> 00:07:49.360
more still to come on space time. Scientists have identified
117
00:07:49.360 --> 00:07:52.439
geological features on Mars that appear to point to a
118
00:07:52.600 --> 00:07:57.120
vast seashore or coastline stretching around the red planet's northern hemisphere.
119
00:07:57.680 --> 00:08:00.839
The findings were reported in the journal Nature, support the
120
00:08:00.879 --> 00:08:04.120
idea of an ancient Martian ocean which once covered a
121
00:08:04.160 --> 00:08:07.680
third of the planet's northern hemisphere. Low Lands, one of
122
00:08:07.680 --> 00:08:10.920
the studies author's, Michael lamp from cow Tech, says that
123
00:08:11.040 --> 00:08:14.160
as a key ingredient for life, water and other bodies
124
00:08:14.199 --> 00:08:18.079
in our Solar system is a major area of research now.
125
00:08:18.120 --> 00:08:21.079
While it's widely accepted that Mars once had some liquid
126
00:08:21.120 --> 00:08:24.079
water on its surface, it's still uncly whether that water
127
00:08:24.439 --> 00:08:27.000
was limited to leaks and streams, or if there was
128
00:08:27.040 --> 00:08:31.040
sufficient to form a long lasting ocean. Past Mars missions
129
00:08:31.040 --> 00:08:34.679
have discovered geological features that look like beaches and shorelines,
130
00:08:35.000 --> 00:08:38.200
but they're subtle and are found at varying elevations across
131
00:08:38.240 --> 00:08:41.639
the planet. Now, if they're true signatures of a stable,
132
00:08:41.720 --> 00:08:45.200
long lasting ocean. These shorelines will need to albeit roughly
133
00:08:45.240 --> 00:08:48.240
the same elevation, in the same way that sea levels
134
00:08:48.240 --> 00:08:51.879
here on Earth are consistent across the planet. Lamb says,
135
00:08:52.000 --> 00:08:54.559
if Mars did have an ocean, must have dried up
136
00:08:54.600 --> 00:08:57.919
long ago, possibly several billion years ago, more than half
137
00:08:57.919 --> 00:09:00.759
the age of the planet itself. He points out there's
138
00:09:00.799 --> 00:09:04.279
hardly anything on Earth that old. Anything on Mars from
139
00:09:04.279 --> 00:09:07.440
that time would have been eroded by billions of years
140
00:09:07.480 --> 00:09:12.679
of wind blowing, volcanoes erupting in other disturbances, removing subtle features.
141
00:09:13.480 --> 00:09:17.240
So Lambing colleagues needed to find a better topographical feature
142
00:09:17.240 --> 00:09:20.480
than shorelines, a feature that could be evidence of an ocean.
143
00:09:21.120 --> 00:09:24.159
They started by first looking to the Earth to determine
144
00:09:24.200 --> 00:09:28.039
which geological features are indicative of an ocean. Here, they
145
00:09:28.120 --> 00:09:31.360
use computer simulations to dry up the Earth's oceans and
146
00:09:31.440 --> 00:09:35.360
see what topographical features remained. The model showed the most
147
00:09:35.360 --> 00:09:38.360
distinct feature of the oceans is a flat band of
148
00:09:38.480 --> 00:09:41.720
lad up to several hundred kilometers wide, wrapping around the
149
00:09:41.759 --> 00:09:45.039
contours where land meets ocean, like a ring that remains
150
00:09:45.080 --> 00:09:49.440
around a drained bathtub. This band is called the continental shelf.
151
00:09:50.120 --> 00:09:52.960
Those sea levels on Earth and thus the location of
152
00:09:53.000 --> 00:09:56.759
the seashells, have fluctuated over many years. The continental shelf
153
00:09:56.919 --> 00:10:00.919
is a large landform that's relatively stable over to iological time.
154
00:10:01.679 --> 00:10:04.600
The authors then looked at topographical data for Mars taken
155
00:10:04.600 --> 00:10:08.320
by orbiters and found an analogous band that is suggestive
156
00:10:08.399 --> 00:10:11.320
of an ocean in the northern Martian hemisphere, covering about
157
00:10:11.360 --> 00:10:14.679
a third of the planet's surface. Lamb points out that
158
00:10:14.720 --> 00:10:17.919
a landform like this takes time to form, and notably
159
00:10:18.000 --> 00:10:21.440
it's not found around lakes. That indicates the ocean must
160
00:10:21.440 --> 00:10:25.360
have existed stably for possibly millions of years. Lamb and
161
00:10:25.399 --> 00:10:29.000
colleagues also saw evidence that river deltas, the triangular plains
162
00:10:29.000 --> 00:10:31.919
of sediment created where rivers spill into the oceans, lined
163
00:10:32.000 --> 00:10:35.720
up with the bathtub ring itself. So this shelf is
164
00:10:35.759 --> 00:10:39.039
a new observation that ties together evidence of what the
165
00:10:39.080 --> 00:10:42.159
coastal zone would have looked like, and the thing is,
166
00:10:42.320 --> 00:10:45.600
no one's really looked for it before. Consequently, this study
167
00:10:45.679 --> 00:10:49.639
suggests new targets for future missions, and the interesting point
168
00:10:49.720 --> 00:10:53.360
is this, if there ever was life on Mars, sedimentary
169
00:10:53.399 --> 00:10:57.759
deposits on the Martian coastlines may well have preserved signatures
170
00:10:57.799 --> 00:11:00.440
in the same way that coastal sediments here on Earth
171
00:11:00.559 --> 00:11:04.720
contain a real historic record of fossils from the early continents.
172
00:11:05.240 --> 00:11:08.679
It's a fascinating target and one which run Dadley be
173
00:11:08.799 --> 00:11:13.320
studied in great detail. This is space time still to
174
00:11:13.360 --> 00:11:16.559
come a just reward for studying the stars, and later
175
00:11:16.600 --> 00:11:20.240
in the Science report ancient rock art showing that Tasmanian
176
00:11:20.360 --> 00:11:24.519
tigers thylocenes may have roam the Australian mainland as recently
177
00:11:24.559 --> 00:11:27.480
as one thousand years ago. All that and more still
178
00:11:27.480 --> 00:11:47.879
to come on space time. Today, citizens, scientists astronomers play
179
00:11:47.919 --> 00:11:50.879
a crucial role in our study of the heavens. As
180
00:11:50.879 --> 00:11:53.720
well as making their own discoveries, which they've always done,
181
00:11:53.799 --> 00:11:57.600
they provide additional supplementary observations which help the universities and
182
00:11:57.639 --> 00:12:00.840
astronomical agencies fill in the gaps in their own research.
183
00:12:01.519 --> 00:12:05.000
In recognition of this important work, every two years, the
184
00:12:05.039 --> 00:12:08.480
Astronomical Society of Australia awards a medal to those who
185
00:12:08.480 --> 00:12:12.000
have worked hard to help advance sciences understanding of the cosmos.

excellence in Amateur Astronomy for twenty twenty six have been
188
00:12:18.639 --> 00:12:23.039
presented to Chris Stockdale, Jonathan Bradshaw and Renato Langerzek at
189
00:12:23.080 --> 00:12:27.360
the annual National Australian Convention of Amateur Astronomers held in Tamworth.
190
00:12:28.120 --> 00:12:32.519
Stockdale co discovered an ultra hot neptune for super Jupiters
191
00:12:32.559 --> 00:12:37.240
and several potential earthlike planets orbiting distant stars Oliver using
192
00:12:37.240 --> 00:12:41.759
a telescope housed in his backyard, Doman Hazelwood in Victorious, Gippsland.
193
00:12:42.320 --> 00:12:46.000
He's co authored over a hundred planetary discovery papers in
194
00:12:46.080 --> 00:12:50.399
science journals including Nature. Bradshaw and Langazec, together with past
195
00:12:50.480 --> 00:12:53.960
Page Medal winner John Broughton, discovered a debris ring around
196
00:12:54.000 --> 00:12:57.440
the arter Krper Belt dwarf planet Quahor, and the fascinating
197
00:12:57.480 --> 00:13:00.840
thing is this ring wasn't detected close to the dwarf planet,
198
00:13:00.960 --> 00:13:03.320
but some four thousand killer it is above the surface
199
00:13:03.360 --> 00:13:05.960
of the frozen world, far beyond the roch limit, the
200
00:13:06.000 --> 00:13:08.759
point where a celestial bodies gravity should tear an orbiting
201
00:13:08.799 --> 00:13:11.960
body apart or prevent the breed from cold lissen together
202
00:13:12.039 --> 00:13:16.080
to former Moon. They work using their own backyard telescopes
203
00:13:16.080 --> 00:13:18.440
on the Gold Coast and the Brisbane suburb of Sanford
204
00:13:18.600 --> 00:13:21.960
was also reported in the journal Nature. Bradshaw says that
205
00:13:22.000 --> 00:13:25.399
discovery was made thanks on occultation as the Pluto sized
206
00:13:25.440 --> 00:13:28.679
dwarf planet passed in front of a distant background star.
207
00:13:28.960 --> 00:13:33.159
What we did is we are all keen ocultation observers,
208
00:13:33.200 --> 00:13:38.320
and ocultations are simply when a dark body object such
209
00:13:38.320 --> 00:13:41.320
as an asteroid, goes in front of an innocent star
210
00:13:41.440 --> 00:13:43.399
out there and it blocks it out for a short
211
00:13:43.440 --> 00:13:46.320
period of time, actually cast a shadow on the Earth.
212
00:13:46.360 --> 00:13:49.639
The shadows pretty much the size of the object inquires
213
00:13:49.679 --> 00:13:53.080
about a thousand longters across, and we were looking to
214
00:13:53.159 --> 00:13:57.120
see if we could detect the position of Quaha. But
215
00:13:57.279 --> 00:14:00.519
in our particular case, it was predicted to vex miss
216
00:14:00.600 --> 00:14:02.799
us altogether. It was going to hit The shadow was
217
00:14:02.799 --> 00:14:04.799
going to go across New Zealand, and it was going
218
00:14:04.879 --> 00:14:09.000
to go across southeastern Australia, but not Queensland where we were.
219
00:14:09.159 --> 00:14:11.759
So we went hunting. We went hunting for a moon,
220
00:14:12.039 --> 00:14:14.120
which was a one in a billion chance, but we
221
00:14:14.159 --> 00:14:16.399
thought we'd give it a go anyway because it's already
222
00:14:16.440 --> 00:14:18.960
got one known moon. So we were calling nice and
223
00:14:19.000 --> 00:14:22.159
early and we didn't discover a moon. We discovered a ring,
224
00:14:22.840 --> 00:14:25.080
and the ring was in the wrong place. And that's
225
00:14:25.120 --> 00:14:28.679
what made it so particularly interesting. It's actually defying the
226
00:14:28.679 --> 00:14:30.799
theoretical physics where a ring sould be.
227
00:14:31.120 --> 00:14:34.600
This ring was discovered four thousand killing. It is above
228
00:14:34.639 --> 00:14:37.720
this twolf planet. Well would normally assume that's will beyond
229
00:14:37.720 --> 00:14:39.799
the Roch limits. That's too far away.
230
00:14:39.919 --> 00:14:44.399
Oh, absolutely so. I mean when Edward Roche first proposed
231
00:14:44.399 --> 00:14:47.519
a limit, he had a sample of one thing in
232
00:14:47.559 --> 00:14:50.840
the universe at the time, which was Saturn, and they
233
00:14:50.960 --> 00:14:53.519
did the physics. The clever fell up did the physics
234
00:14:53.559 --> 00:14:57.600
and worked out that pretty much anything outside further away
235
00:14:57.679 --> 00:14:59.919
than the current limit of Saturn's ring that we can
236
00:15:00.120 --> 00:15:04.639
see any matter that was coalescing there would form a moon,
237
00:15:04.919 --> 00:15:08.240
and anything inside that limit would be torn apart by
238
00:15:08.279 --> 00:15:11.039
the gravitational forces of the main body and would be
239
00:15:11.080 --> 00:15:13.480
a ring. And that was just fine because they went
240
00:15:13.559 --> 00:15:18.000
and discovered other rings. So there was some rings around Uranus,
241
00:15:18.200 --> 00:15:22.879
and ring fragments around Neptune and then Shariquo. So all
242
00:15:22.919 --> 00:15:26.720
in all, up until our discovery, there were five ring
243
00:15:26.840 --> 00:15:31.240
systems known, and they all conformed beautifully to the roach limit.
