1
00:00:01,700 --> 00:00:03,101
Imagine a place
2
00:00:03,102 --> 00:00:06,705
Surrounded by glacial rock trillions
3
00:00:06,706 --> 00:00:08,907
... a mysterious dwarf star
4
00:00:11,277 --> 00:00:16,714
A ball of magnetic bubbles
Each offering 100 million miles
5
00:00:16,715 --> 00:00:22,121
Destroyed by a global war between deadly radiation fields
6
00:00:24,322 --> 00:00:27,525
That is not a distant area of ??a galaxy
7
00:00:27,526 --> 00:00:30,661
It is our creativity ... our solar system
8
00:00:30,662 --> 00:00:34,164
And what happens within it
9
00:00:34,165 --> 00:00:38,171
Separates our life or our death
10
00:00:46,455 --> 00:00:52,327
"The Ways of the Universe"
11
00:00:55,287 --> 00:00:56,788
{\ A10} over the past century
12
00:00:56,789 --> 00:00:59,858
{\ A10} Our understanding of the universe increased greatly
13
00:01:02,762 --> 00:01:05,698
We have discovered billions of stars in our galaxy
14
00:01:05,699 --> 00:01:09,935
And billions of new galaxies across the universe
15
00:01:13,039 --> 00:01:17,375
We saw black holes shooting cosmic rivals
16
00:01:17,376 --> 00:01:19,377
... and Ngooma is a nuclear explosive
17
00:01:21,013 --> 00:01:25,384
And new planets in distant solar systems
18
00:01:25,385 --> 00:01:28,153
But when it comes to our cosmic title
19
00:01:28,154 --> 00:01:31,389
We hardly know much
20
00:01:31,390 --> 00:01:33,758
When we study space
21
00:01:33,759 --> 00:01:35,592
The closest thing to us is our solar system
22
00:01:35,593 --> 00:01:37,428
This is what we understand best
23
00:01:37,429 --> 00:01:39,764
But it is clear that we are at the beginning of the road
24
00:01:39,765 --> 00:01:42,533
We do not understand anything in our solar system
25
00:01:42,534 --> 00:01:45,202
The solar system is our home, our neighbor
26
00:01:45,203 --> 00:01:46,770
But you might be surprised to find out
27
00:01:46,771 --> 00:01:50,341
We do not really understand how wide it is
28
00:01:50,342 --> 00:01:53,211
When I was a boy, I learned
29
00:01:53,212 --> 00:01:56,014
Order of planets in the solar system
30
00:01:56,015 --> 00:01:58,282
It was the farthest planet Pluto
31
00:01:58,283 --> 00:02:00,085
The solar system stopped there
32
00:02:00,086 --> 00:02:03,288
This was completely wrong
33
00:02:03,289 --> 00:02:05,655
If you think the solar system ends
34
00:02:05,656 --> 00:02:08,592
With the end of the planets, where Neptune and Pluto
35
00:02:08,593 --> 00:02:12,131
You are missing the bigger picture
36
00:02:13,699 --> 00:02:17,269
... We just started knowing the amazing fact
37
00:02:17,270 --> 00:02:24,608
More than ninety percent of our system
The solar begins where planets end
38
00:02:24,609 --> 00:02:27,544
When the sunlight reaches this distance
39
00:02:27,545 --> 00:02:29,649
They are very weak
40
00:02:30,716 --> 00:02:32,817
But we knew there was something there
41
00:02:32,818 --> 00:02:36,019
Because he has been sending us visitors
42
00:02:36,020 --> 00:02:38,557
Comets
43
00:02:42,526 --> 00:02:47,264
It was assumed to come from a mysterious disk
44
00:02:47,265 --> 00:02:49,567
Behind the Neptune orbit
45
00:02:49,568 --> 00:02:52,538
But no one has
46
00:02:53,938 --> 00:02:56,174
The Quiber belt was theoretical
47
00:02:56,175 --> 00:02:57,674
He was believed to exist
48
00:02:57,675 --> 00:02:59,543
But he also thought it was difficult to observe
49
00:02:59,544 --> 00:03:01,079
We are talking about Agram
50
00:03:01,080 --> 00:03:03,182
It may reach 100 miles
51
00:03:03,183 --> 00:03:05,716
But it is billions of miles away
52
00:03:05,717 --> 00:03:09,086
Try to find something much smaller
53
00:03:09,087 --> 00:03:10,187
It will be extremely difficult
54
00:03:10,188 --> 00:03:11,858
No one thought of doing it
55
00:03:15,627 --> 00:03:18,729
In 1986, a team of astronomers
56
00:03:18,730 --> 00:03:21,532
"Stationed at the Muna Kia Observatory in Hawaii
57
00:03:21,533 --> 00:03:24,470
They decided to prove their mistake
58
00:03:26,271 --> 00:03:28,006
I usually store
59
00:03:28,007 --> 00:03:32,876
These observations were taken when we were watching
60
00:03:32,877 --> 00:03:35,380
I used to write a lot of things in a blog
61
00:03:35,381 --> 00:03:37,482
To try to track
62
00:03:37,483 --> 00:03:40,116
Everything that happens on top of the mountain
63
00:03:40,117 --> 00:03:42,019
Here is the name of the telescope
64
00:03:42,020 --> 00:03:44,021
, "80-inch telescope on" Mona Kia
65
00:03:44,022 --> 00:03:46,591
"Also known as" Rust Baket
66
00:03:48,393 --> 00:03:49,860
Visitors to this telescope
67
00:03:49,861 --> 00:03:51,495
They always think that it was the ugliest thing they saw
68
00:03:51,496 --> 00:03:52,562
It is brown
69
00:03:52,563 --> 00:03:54,364
Sounds like rusty
70
00:03:54,365 --> 00:03:55,532
Parts of it are rusty
71
00:03:55,533 --> 00:03:57,268
So it's a gruesome-looking telescope
72
00:03:57,269 --> 00:03:59,204
But we use it in all our work
73
00:03:59,205 --> 00:04:01,807
If they could locate a particle beyond the planets
74
00:04:01,808 --> 00:04:05,410
He must have a Kuiper Belt
75
00:04:05,411 --> 00:04:08,545
They did not find anything for six years
76
00:04:08,546 --> 00:04:09,646
It's like research
77
00:04:09,647 --> 00:04:13,116
"For a rusty coin in the state of Texas
Games
00:04:13,117 --> 00:04:14,884
We spent many years
78
00:04:14,885 --> 00:04:16,820
We look for particles in the outer solar system
79
00:04:16,821 --> 00:04:20,358
Too tired
Lots of disappointment
80
00:04:20,359 --> 00:04:24,029
We respect the size of the objects
81
00:04:24,030 --> 00:04:26,296
Yes we can see the stars at a distance
82
00:04:26,297 --> 00:04:28,031
Hundreds of thousands of light years
83
00:04:28,032 --> 00:04:30,134
But they are big glowing objects
84
00:04:30,135 --> 00:04:32,504
How can you see a particle that is only 100 miles wide
85
00:04:32,505 --> 00:04:33,805
Is it unclear?
86
00:04:33,806 --> 00:04:36,207
It does not produce any light visible from itself
87
00:04:36,208 --> 00:04:38,143
That's why finding these things is difficult
88
00:04:39,445 --> 00:04:42,949
The Kuiper belt particles consist mainly of ice
89
00:04:44,249 --> 00:04:48,286
So you might think it sparkles like icebergs
90
00:04:51,857 --> 00:04:54,158
We are in a volcanic country
91
00:04:54,159 --> 00:04:57,529
So most of these peaks are dark and covered with ash
92
00:04:57,530 --> 00:04:59,896
They are quite symmetrical
93
00:04:59,897 --> 00:05:02,199
"Belt particles" Kuiper
94
00:05:02,200 --> 00:05:04,000
So I wanted to get closer to this
95
00:05:04,001 --> 00:05:05,937
But my mentor told me it was huge
96
00:05:05,938 --> 00:05:08,875
We can not approach, may turn
97
00:05:10,075 --> 00:05:11,843
Well, we found a good one
98
00:05:11,844 --> 00:05:13,144
It is very dark
99
00:05:13,145 --> 00:05:14,611
Let's get up there
100
00:05:14,612 --> 00:05:17,415
Look how dark this is from the outside?
101
00:05:17,416 --> 00:05:20,517
Well, the comets are also black
102
00:05:20,518 --> 00:05:23,019
But in fact, I was tired of this
103
00:05:23,020 --> 00:05:25,757
We believe that comets are darkened by asphalt
104
00:05:25,758 --> 00:05:27,560
Black of tar
105
00:05:29,561 --> 00:05:32,031
Kuiper's dark-brown particles
106
00:05:32,032 --> 00:05:34,498
Remained hidden for half a decade
107
00:05:35,933 --> 00:05:40,504
Then on a summer night
Joyce and his team monitored something
108
00:05:40,505 --> 00:05:45,310
The solar system will never be as it was
109
00:05:45,311 --> 00:05:48,545
So here you register
110
00:05:48,546 --> 00:05:50,180
Blogs we keep as we watch
111
00:05:50,181 --> 00:05:54,050
August 29, 1992
112
00:05:54,051 --> 00:05:55,385
We started as usual
113
00:05:55,386 --> 00:05:57,956
Look at the pictures that come from the telescope
114
00:05:57,957 --> 00:06:01,091
We discovered this first particle
115
00:06:01,092 --> 00:06:02,927
It was one small point
116
00:06:02,928 --> 00:06:05,596
Moving very slowly across the sky
117
00:06:05,597 --> 00:06:08,899
His path showed that he was circling the sun
118
00:06:08,900 --> 00:06:13,103
But in an orbit that takes him far behind the planets
119
00:06:13,104 --> 00:06:17,642
The orbit puts him in the mysterious "Quiber" belt
120
00:06:17,643 --> 00:06:20,110
He was moving very slowly across the sky
121
00:06:20,111 --> 00:06:22,180
That was too far away
122
00:06:22,181 --> 00:06:24,216
We realized the slow speed
123
00:06:24,217 --> 00:06:26,817
It was far beyond a particle
124
00:06:26,818 --> 00:06:29,821
It was seen in the system
So solar to that point
125
00:06:32,023 --> 00:06:33,892
Here 's that blog
126
00:06:33,893 --> 00:06:35,993
"A slow moving particle ... a question mark"
127
00:06:35,994 --> 00:06:38,663
This is if the Kuiper belt is discovered there
128
00:06:38,664 --> 00:06:40,565
It was those three letters
129
00:06:40,566 --> 00:06:45,235
In a moment, the Quiber belt became real
130
00:06:45,236 --> 00:06:46,837
And so
131
00:06:46,838 --> 00:06:49,740
Our solar system is twice the size
132
00:06:49,741 --> 00:06:52,677
... It was a scientific leap because we now have this
133
00:06:52,678 --> 00:06:54,879
This whole part of the solar system
134
00:06:54,880 --> 00:06:57,682
Which we predicted without proof
135
00:06:57,683 --> 00:06:58,717
Evidence
136
00:07:00,751 --> 00:07:03,154
"Discovery of the first particle of the belt" Kuiper
137
00:07:03,155 --> 00:07:05,156
It was a clear indication of existence
138
00:07:05,157 --> 00:07:07,358
New numbers of bodies there
139
00:07:07,359 --> 00:07:08,593
Throughout the night
140
00:07:08,594 --> 00:07:11,163
We have doubled the solar system
141
00:07:13,931 --> 00:07:15,166
The team was later known
142
00:07:15,167 --> 00:07:17,401
"On several other bodies of the belt" Quiber
143
00:07:17,402 --> 00:07:20,904
They ended up calculating the billions of particles
144
00:07:20,905 --> 00:07:24,541
Which revolves around the sun in a vast disk
145
00:07:24,542 --> 00:07:25,944
It was the first guide
146
00:07:25,945 --> 00:07:29,346
Our solar system hides us great surprises
147
00:07:29,347 --> 00:07:35,252
Far from what we thought was the end of the solar system
148
00:07:35,253 --> 00:07:37,187
"Discovery of the first particle of the belt" Kuiper
149
00:07:37,188 --> 00:07:40,257
It was a remarkable achievement
150
00:07:40,258 --> 00:07:44,127
It was a guide to the existence of a whole group
151
00:07:44,128 --> 00:07:46,497
Of the bodies in the solar system
152
00:07:46,498 --> 00:07:50,534
, Which we thought existed
Then we discovered the truth
153
00:07:50,535 --> 00:07:52,670
It was a great discovery as a discovery
154
00:07:52,671 --> 00:07:54,307
Full planet for example
155
00:07:57,342 --> 00:07:59,677
Discover the Kuiper Belt
156
00:07:59,678 --> 00:08:02,214
Instantly increased the size of our solar system
157
00:08:02,215 --> 00:08:05,348
But reduced the status of one member
158
00:08:05,349 --> 00:08:08,586
Because some objects in the belt
159
00:08:08,587 --> 00:08:12,322
They were bigger than our smallest planets
160
00:08:12,323 --> 00:08:16,528
Pluto was demoted to a dwarf planet
161
00:08:18,095 --> 00:08:19,964
I really enjoyed the conflict
162
00:08:19,965 --> 00:08:21,098
About Pluto Description
163
00:08:21,099 --> 00:08:22,632
Is it a planet?
Is it a dwarf planet?
164
00:08:22,633 --> 00:08:25,803
Is it something between them?
It shows how interested people are
165
00:08:25,804 --> 00:08:27,070
Pluto is still charming
166
00:08:27,071 --> 00:08:29,339
Is still an important part of our solar system
167
00:08:29,340 --> 00:08:33,077
But we see him as the nearest neighbor
168
00:08:33,078 --> 00:08:34,245
Let's not get angry
169
00:08:34,246 --> 00:08:35,645
That Pluto is no longer called a planet
170
00:08:35,646 --> 00:08:38,682
Take care of the fact that Pluto is a dwarf planet
171
00:08:38,683 --> 00:08:41,686
He can teach us a lot of
Things about all his new friends
172
00:08:41,687 --> 00:08:43,956
Which we discover year after year
173
00:08:44,957 --> 00:08:48,625
Pluto now has more than 1,400 brothers and sisters
174
00:08:48,626 --> 00:08:51,495
They are called plutonoids
175
00:08:51,496 --> 00:08:53,663
If Pluto was a planet, so would all plutonoids
176
00:08:53,664 --> 00:08:56,165
I have a sister, it will be difficult for her
177
00:08:56,166 --> 00:08:58,303
Try to remember all those names
178
00:09:00,672 --> 00:09:02,441
Discover the Kuiper Belt
179
00:09:02,442 --> 00:09:05,576
Open the solar system
180
00:09:05,577 --> 00:09:08,979
But it was just the beginning of our expedition
181
00:09:08,980 --> 00:09:11,116
To the outer border
182
00:09:15,120 --> 00:09:18,322
The Kuiper belt distance from the sun is fifty times longer
183
00:09:18,323 --> 00:09:20,423
From the Earth's distance from the sun
184
00:09:20,424 --> 00:09:21,891
it's huge
185
00:09:21,892 --> 00:09:23,928
But if you think the boundaries of the Kuiper belt
186
00:09:23,929 --> 00:09:25,529
Is the limits of the solar system
187
00:09:25,530 --> 00:09:27,398
You think in a shallow way
188
00:09:27,399 --> 00:09:30,067
Behind the Quiber Belt far away
189
00:09:30,068 --> 00:09:33,404
The sun was reflected in a reflective shield
190
00:09:33,405 --> 00:09:35,105
About the solar system
191
00:09:35,106 --> 00:09:37,841
Our star is waging a global war
192
00:09:37,842 --> 00:09:41,513
Against the largest weapons in the galaxy
193
00:09:41,514 --> 00:09:45,084
Our lives depend on their success
194
00:09:51,700 --> 00:09:53,200
, For a long time
195
00:09:53,201 --> 00:09:57,038
We assumed that the solar system
Ends with the end of the planets
196
00:09:57,039 --> 00:09:59,841
But the Kuiper belt was discovered in the 1990s
197
00:09:59,842 --> 00:10:02,311
He multiplied the effect of the sun
198
00:10:02,312 --> 00:10:06,814
The question raised scholars
"Can they go further?"
199
00:10:06,815 --> 00:10:10,318
It turned out to be true, much further
200
00:10:10,319 --> 00:10:13,354
We would not live if we could not
201
00:10:13,355 --> 00:10:16,424
If you put a Geiger counter
In this room he will move
202
00:10:16,425 --> 00:10:18,391
If you put a Geiger counter in space
203
00:10:18,392 --> 00:10:19,660
Move more
204
00:10:19,661 --> 00:10:23,397
It monitors a deadly kind of radiation
205
00:10:23,398 --> 00:10:24,899
Called cosmic rays
206
00:10:24,900 --> 00:10:28,335
Cosmic rays are essentially atomic particles
207
00:10:28,336 --> 00:10:32,006
Such as helium atoms, protons and electrons
208
00:10:32,007 --> 00:10:35,108
Which jumps through space at almost the speed of light
209
00:10:35,109 --> 00:10:37,344
They can travel far distances
210
00:10:37,345 --> 00:10:39,113
Hundreds and thousands of light years
211
00:10:39,114 --> 00:10:42,284
It is clear that they are hitting us here on the ground
212
00:10:44,252 --> 00:10:47,221
Cosmic rays explode from exploding stars
213
00:10:47,222 --> 00:10:49,592
Deep in the galaxy
214
00:10:50,892 --> 00:10:53,261
They are incompatible with life
215
00:10:53,262 --> 00:10:56,329
They can tear apart the electrons
216
00:10:56,330 --> 00:10:58,065
It can really change
217
00:10:58,066 --> 00:11:02,069
The chemical arrangement of cells causes mutations
218
00:11:02,070 --> 00:11:05,439
It can kill you
219
00:11:05,440 --> 00:11:08,876
If the earth was constantly hit by cosmic rays
220
00:11:08,877 --> 00:11:10,343
Without any protection
221
00:11:10,344 --> 00:11:13,780
They would not survive the advanced forms of life
222
00:11:13,781 --> 00:11:17,285
But cosmic rays rarely target us
223
00:11:17,286 --> 00:11:18,986
They rarely hit us in truth
224
00:11:18,987 --> 00:11:22,423
Clearly there is something to protect us
225
00:11:22,424 --> 00:11:26,629
Of the complete attack of cosmic rays from the universe
226
00:11:28,964 --> 00:11:30,964
It is our sun
227
00:11:30,965 --> 00:11:35,535
A reversible shield of 8.7 billion miles is made
228
00:11:35,536 --> 00:11:37,304
Towards space
229
00:11:37,305 --> 00:11:41,976
Using its solar wind
230
00:11:41,977 --> 00:11:43,243
When you think about the wind
231
00:11:43,244 --> 00:11:44,377
Think of the earth's air
232
00:11:44,378 --> 00:11:45,880
Which moves through your hair
233
00:11:45,881 --> 00:11:47,750
Solar wind is not
234
00:11:47,751 --> 00:11:50,251
It is really a torrent of high-energy particles
235
00:11:50,252 --> 00:11:52,453
It emanates from the sun, such as hydrogen
236
00:11:52,454 --> 00:11:56,058
It's real, it's billions of tons every second
237
00:11:56,059 --> 00:11:58,858
Some parts of solar wind move
238
00:11:58,859 --> 00:12:01,029
At about two million miles per hour
239
00:12:01,030 --> 00:12:02,664
Has a strong impact
240
00:12:02,665 --> 00:12:05,800
Blow beside us here on the ground
241
00:12:05,801 --> 00:12:09,104
Because the magnetic field of the earth reflects them
242
00:12:12,874 --> 00:12:15,108
Solar wind does not stop at Earth
243
00:12:15,109 --> 00:12:16,844
It's in space, it keeps moving
244
00:12:16,845 --> 00:12:18,545
It goes beyond the inner planets
245
00:12:18,546 --> 00:12:20,381
... goes beyond the outer planets
246
00:12:20,382 --> 00:12:22,416
.... Jupiter, Saturn, Uranus and Neptune
247
00:12:22,417 --> 00:12:24,318
And continue to move
248
00:12:24,319 --> 00:12:26,755
It goes beyond the Quiber belt
249
00:12:26,756 --> 00:12:28,656
Carrying the magnetic field of the sun
250
00:12:28,657 --> 00:12:31,092
3.5 billion miles away
251
00:12:31,093 --> 00:12:33,795
You make a huge defensive shield
252
00:12:33,796 --> 00:12:37,365
About the solar system is called the solar envelope
253
00:12:37,366 --> 00:12:39,268
Solar wind blows a bubble
254
00:12:39,269 --> 00:12:40,568
About our solar system
255
00:12:40,569 --> 00:12:43,337
The sun is like a big mother
256
00:12:43,338 --> 00:12:46,740
Already made a bubble of charged particles
257
00:12:46,741 --> 00:12:49,178
And the associated magnetic fields that protect us
258
00:12:49,179 --> 00:12:53,014
Of the cosmic rays that come
From outside the solar system
259
00:12:53,015 --> 00:12:56,016
The next cosmic rays
260
00:12:56,017 --> 00:12:58,352
Collide with solar wind
261
00:12:58,353 --> 00:13:01,356
Most of them turn into space
262
00:13:01,357 --> 00:13:07,328
Without this draw in the spaces of space to destroy us
263
00:13:07,329 --> 00:13:08,630
Like anything else in nature
264
00:13:08,631 --> 00:13:10,598
Solar wind is a double edged sword
265
00:13:10,599 --> 00:13:13,568
They can hurt us here on the ground
But it also protects us
266
00:13:13,569 --> 00:13:15,437
Of those materials
267
00:13:15,438 --> 00:13:17,671
There are many models in the universe
268
00:13:17,672 --> 00:13:18,973
Where you think nothing
269
00:13:18,974 --> 00:13:21,074
It is at first dangerous and very destructive
270
00:13:21,075 --> 00:13:22,376
It can be protective
271
00:13:22,377 --> 00:13:24,478
And solar wind one of them
272
00:13:24,479 --> 00:13:27,649
Yes, there are those particles
High energy coming from the sun
273
00:13:27,650 --> 00:13:29,617
But the impact of solar wind
274
00:13:29,618 --> 00:13:31,919
Protect our entire solar system
275
00:13:31,920 --> 00:13:34,555
Of more dangerous particles
276
00:13:34,556 --> 00:13:37,223
The protective bubble is making its way
277
00:13:37,224 --> 00:13:38,892
Through dust and gases
278
00:13:38,893 --> 00:13:43,363
Where the solar system revolves
I'm talking about the center of the galaxy
279
00:13:43,364 --> 00:13:46,333
They make their way as the boat moves through the water
280
00:13:46,334 --> 00:13:50,371
A wave is slowing down
Solar wind to be stopped
281
00:13:50,372 --> 00:13:52,274
Where it collides with materials
282
00:13:52,275 --> 00:13:55,008
Outside the solar system, into interstellar space
283
00:13:55,009 --> 00:13:56,578
And here
284
00:13:56,579 --> 00:14:00,647
NASA explorers found the boundaries
"Interstellar") or "IPX"
285
00:14:00,648 --> 00:14:04,084
On a very strange and completely unexpected phenomenon
286
00:14:04,085 --> 00:14:06,352
The mission of "Ipex" already exists
287
00:14:06,353 --> 00:14:08,990
A huge emitter of hydrogen gas
288
00:14:08,991 --> 00:14:11,460
The biggest thing we saw
In our solar system so far
289
00:14:11,461 --> 00:14:13,328
It may be the result of interaction
290
00:14:13,329 --> 00:14:15,096
The magnetic field of our solar system
291
00:14:15,097 --> 00:14:18,233
With a larger magnetic field for the galaxy
292
00:14:21,435 --> 00:14:24,038
Scientists believe that interaction
293
00:14:24,039 --> 00:14:26,308
Between the solar wind of the sun and the outside
294
00:14:26,309 --> 00:14:29,142
And the interstellar medium of the galaxy's inward drive
295
00:14:29,143 --> 00:14:33,048
The particles are trapped in a huge bar
296
00:14:40,622 --> 00:14:45,193
... The length of the ribbon is about a hundred billion miles
297
00:14:46,460 --> 00:14:51,998
Making it the largest particle in our solar system
298
00:14:51,999 --> 00:14:54,269
It's interesting to know
299
00:14:54,270 --> 00:14:57,637
For these long structures at the edge of the solar system
300
00:14:57,638 --> 00:14:59,140
Because frankly, no one expected it
301
00:14:59,141 --> 00:15:00,574
No one organized it
302
00:15:00,575 --> 00:15:03,144
So by seeing something we never expected before
303
00:15:03,145 --> 00:15:04,477
That is how we learn
304
00:15:04,478 --> 00:15:06,313
And so the flag advances
305
00:15:06,314 --> 00:15:10,184
IPEX "and its technology in the 21st century"
306
00:15:10,185 --> 00:15:14,588
Tell us amazing new things about our solar system
307
00:15:14,589 --> 00:15:18,426
But its old technique has not
It was drained from the 1970s
308
00:15:18,427 --> 00:15:21,328
Has been sending the most exciting news
309
00:15:21,329 --> 00:15:23,997
Of the outer border
310
00:15:23,998 --> 00:15:26,199
After traveling for about forty years
311
00:15:26,200 --> 00:15:29,502
Voyager continues to send messages to us
312
00:15:29,503 --> 00:15:33,875
Around the strange areas of huge magnetic bubbles
313
00:15:33,876 --> 00:15:36,776
And a high-energy giant competitor
314
00:15:36,777 --> 00:15:39,514
It explodes from our solar system
315
00:15:46,000 --> 00:15:47,835
In the past few decades
316
00:15:47,836 --> 00:15:50,568
We realized that our perception of the solar system
317
00:15:50,569 --> 00:15:54,673
He was missing ninety percent of the picture
318
00:15:54,674 --> 00:15:57,409
25 years ago, we thought Pluto
319
00:15:57,410 --> 00:15:59,479
It was the limit of the planets at least in our solar system
320
00:15:59,480 --> 00:16:01,315
But we now know there is
321
00:16:01,316 --> 00:16:03,816
Many others like Pluto are there
322
00:16:03,817 --> 00:16:06,387
So the limits of the solar system have not only widened
323
00:16:06,388 --> 00:16:07,886
But we became more aware
324
00:16:07,887 --> 00:16:09,589
For our need for further learning
325
00:16:11,257 --> 00:16:12,892
Our newest eyes in the sky
326
00:16:12,893 --> 00:16:19,465
Staring in these areas
The most remote of our being next door
327
00:16:19,466 --> 00:16:22,936
We are beginning to learn about the vast system of criminality
328
00:16:22,937 --> 00:16:24,703
In the outer part of our solar system
329
00:16:24,704 --> 00:16:26,338
Increasing our techniques
330
00:16:26,339 --> 00:16:29,008
We continue to discover more
And more UFOs
331
00:16:29,009 --> 00:16:31,744
And our image of the reality of the solar system
332
00:16:31,745 --> 00:16:36,414
Changed as a result of our ability to improve our eyes
333
00:16:36,415 --> 00:16:39,952
But it is a very old technique that really takes us
334
00:16:39,953 --> 00:16:41,655
To those limits
335
00:16:45,592 --> 00:16:48,628
When NASA launched Voyager-A in 1977
336
00:16:48,629 --> 00:16:51,963
They thought it might work for five years
337
00:16:51,964 --> 00:16:55,768
After 37 years, this small space probe
338
00:16:55,769 --> 00:16:59,340
Still sending us amazing information
339
00:17:00,540 --> 00:17:02,042
, In August 2012
340
00:17:02,043 --> 00:17:05,578
It was 11 billion miles from Earth
341
00:17:05,579 --> 00:17:07,414
He left the solar field
342
00:17:07,415 --> 00:17:11,316
The edge of the solar system is completely mysterious
343
00:17:11,317 --> 00:17:14,654
The atmosphere of the sun
344
00:17:14,655 --> 00:17:16,956
Interstellar space
345
00:17:16,957 --> 00:17:20,828
This edge is the intersection of these two extremes
346
00:17:20,829 --> 00:17:23,396
It is a place where our neighborhood ends
347
00:17:23,397 --> 00:17:25,532
The neighborhood begins
three hundred fifty
00:17:25,533 --> 00:17:28,568
"I was struck by news that" Voyager
348
00:17:28,569 --> 00:17:30,468
It was at the edge of the solar system
349
00:17:30,469 --> 00:17:32,371
This is a complete area of ??the solar system
350
00:17:32,372 --> 00:17:34,373
We hardly know anything about it
351
00:17:34,374 --> 00:17:36,543
For the first time in the history of mankind
352
00:17:36,544 --> 00:17:39,078
We have an automatic probe that lies in its center
353
00:17:39,079 --> 00:17:42,247
Measures what goes around
354
00:17:42,248 --> 00:17:44,049
It was amazing
355
00:17:44,050 --> 00:17:46,819
We can say for the first time, even a limited scope
356
00:17:46,820 --> 00:17:49,056
That human type is interstellar
357
00:17:49,057 --> 00:17:51,225
We are now out among the stars
358
00:17:53,660 --> 00:17:56,027
When our brave little probe looked between the stars
359
00:17:56,028 --> 00:17:57,929
On the solar system
360
00:17:57,930 --> 00:18:00,800
He had a surprise for us
361
00:18:00,801 --> 00:18:05,170
We thought that the solar field was in the form of a comet
362
00:18:05,171 --> 00:18:10,010
With a huge tail extending hundreds of billions of miles back
363
00:18:10,011 --> 00:18:14,581
But Voyager discovered something new and amazing
364
00:18:15,983 --> 00:18:19,653
No solar field found
In the form of a giant tail
365
00:18:19,654 --> 00:18:26,226
He found a halo shape with two short sleeves
366
00:18:26,227 --> 00:18:27,793
This is a very important observation
367
00:18:27,794 --> 00:18:29,395
Because they teach us something new
368
00:18:29,396 --> 00:18:30,730
It teaches us the basic form
369
00:18:30,731 --> 00:18:32,098
Of the solar field
370
00:18:32,099 --> 00:18:34,433
I mean it's a long time
We had the simplest picture
371
00:18:34,434 --> 00:18:36,936
But we have the details now
We know that he has some compositions
372
00:18:36,937 --> 00:18:38,537
We can start with that
373
00:18:38,538 --> 00:18:40,439
Let us begin and begin with deep understanding
374
00:18:40,440 --> 00:18:42,242
For the area around the sun
375
00:18:42,243 --> 00:18:49,114
The tail is the wind
Solar High Power
376
00:18:49,115 --> 00:18:51,783
The reason for these jets is pressure
377
00:18:51,784 --> 00:18:55,552
Or interaction between the magnetic field
378
00:18:55,553 --> 00:18:56,688
... for the galaxy in the background and those particles
379
00:18:56,689 --> 00:19:00,060
Charged particles are fast
The flow from the sun
380
00:19:01,961 --> 00:19:05,063
Voyager also sent us shocking news
381
00:19:05,064 --> 00:19:09,135
About the edge of the influence of the sun
382
00:19:09,136 --> 00:19:11,370
Perhaps the edge of the solar field is not quite clear
383
00:19:11,371 --> 00:19:12,537
It is not a dividing line
384
00:19:12,538 --> 00:19:14,274
Is not a definite end
385
00:19:14,275 --> 00:19:16,408
In fact, it is an extended area that is not clear
386
00:19:16,409 --> 00:19:19,145
It's hundreds of millions of miles away
387
00:19:19,146 --> 00:19:20,947
In the middle
388
00:19:20,948 --> 00:19:24,583
... monitoring Voyager is something strange
389
00:19:24,584 --> 00:19:28,720
A ball of huge magnetic bubbles
390
00:19:28,721 --> 00:19:30,657
We thought the solar magnetic field
391
00:19:30,658 --> 00:19:32,658
Scattered at this point
392
00:19:32,659 --> 00:19:34,526
But this did not happen
393
00:19:34,527 --> 00:19:36,862
What they discovered was the magnetic field lines
394
00:19:36,863 --> 00:19:38,264
Of the sun has intertwined
395
00:19:38,265 --> 00:19:42,434
To make a magnetic composition foam thin bubbles
396
00:19:42,435 --> 00:19:46,171
This was a surprise, and an exciting surprise
397
00:19:46,172 --> 00:19:50,575
When the magnetic field of the sun is rippled
398
00:19:50,576 --> 00:19:52,612
It wilts and intertwined
399
00:19:54,346 --> 00:19:56,881
The lines intersect and connect again
400
00:19:56,882 --> 00:19:59,452
To be giant magnetic bubbles
401
00:20:00,954 --> 00:20:04,556
Each bubble is foamy
402
00:20:04,557 --> 00:20:07,993
With a width of about 100 million miles, and that's phenomenal
403
00:20:07,994 --> 00:20:10,231
It is the distance from the earth to the sun
404
00:20:10,232 --> 00:20:12,965
Thousands of them surround the solar system
405
00:20:12,966 --> 00:20:17,703
No one was sure what to do
Those are magnetic bubbles
406
00:20:17,704 --> 00:20:19,670
But it is possible
407
00:20:19,671 --> 00:20:23,075
This is a bubble
Cosmic is the first line of defense
408
00:20:23,076 --> 00:20:24,843
In front of Hungarian radiations
409
00:20:24,844 --> 00:20:27,213
It helps protect the solar system
410
00:20:27,214 --> 00:20:28,914
Of the global aggression
411
00:20:28,915 --> 00:20:31,618
Think about how much technology is different
412
00:20:31,619 --> 00:20:33,753
Since the launch of Voyager until today
413
00:20:33,754 --> 00:20:35,821
No one had a phone in his pocket
414
00:20:35,822 --> 00:20:37,956
I mean no one was even able to
Make a long distance phone call
415
00:20:37,957 --> 00:20:40,391
Across the ocean without being in great distress
416
00:20:40,392 --> 00:20:42,160
But with this old technique
417
00:20:42,161 --> 00:20:43,294
We are learning now
418
00:20:43,295 --> 00:20:45,197
On the edge of the solar system
419
00:20:45,198 --> 00:20:48,501
Imagine what we will learn in the next 50 years
420
00:20:48,502 --> 00:20:50,735
Voyager "after the edge of the solar field now"
421
00:20:50,736 --> 00:20:52,938
Travel through interstellar space
422
00:20:52,939 --> 00:20:56,141
But have you already left the solar system?
423
00:20:56,142 --> 00:20:57,342
Not really
424
00:20:57,343 --> 00:20:59,277
There is a lot of solar system out there
425
00:20:59,278 --> 00:21:01,213
"To pass it" Voyager
426
00:21:01,214 --> 00:21:03,751
And will have to travel for several centuries
427
00:21:03,752 --> 00:21:07,453
And thousands of years before that
The real solar system is leaving
428
00:21:11,291 --> 00:21:15,627
It 's outside the atmosphere of the sun
429
00:21:15,628 --> 00:21:18,198
But did not pass the sun's gravity
430
00:21:20,100 --> 00:21:22,400
"When we go out, we travel in Quiber Belt
431
00:21:22,401 --> 00:21:24,669
Behind the orbit of Pluto, right?
This is too far
432
00:21:24,670 --> 00:21:27,607
Beyond that, we have the edge of the solar field
433
00:21:27,608 --> 00:21:29,140
The area of ??the magnetic field of the sun
434
00:21:29,141 --> 00:21:31,510
So you might think you're at the end of the solar system
435
00:21:31,511 --> 00:21:34,548
But guess
There are still things
436
00:21:34,549 --> 00:21:37,750
Are related to our solar system
437
00:21:40,387 --> 00:21:42,021
,From time to time
438
00:21:42,022 --> 00:21:45,326
Something sends those things accelerating towards the sun
439
00:21:45,327 --> 00:21:49,796
The earth may turn its way
440
00:21:57,903 --> 00:22:00,505
In the far reaches of the solar system
441
00:22:00,506 --> 00:22:04,909
Far from the solar field
442
00:22:04,910 --> 00:22:06,312
We are blind
443
00:22:06,313 --> 00:22:08,680
We can not see in this dimension
444
00:22:08,681 --> 00:22:12,918
But sometimes messengers come from behind
445
00:22:12,919 --> 00:22:17,190
Deadly Messengers .. Comets
446
00:22:26,032 --> 00:22:27,800
There are essentially two comets
447
00:22:27,801 --> 00:22:30,069
There are short comets
448
00:22:30,070 --> 00:22:32,204
The other type of comets are long cycle
449
00:22:32,205 --> 00:22:35,707
"Comets come short-circuited from Quiber's belt
450
00:22:35,708 --> 00:22:39,076
This disc is the remnants of space beyond the planets
451
00:22:39,077 --> 00:22:41,179
She travels around the solar system
452
00:22:41,180 --> 00:22:43,282
In relatively small circles
453
00:22:43,283 --> 00:22:47,921
Returns at regular intervals every 200 years or less
454
00:22:52,025 --> 00:22:55,461
Long comets are more mysterious
455
00:22:57,730 --> 00:22:59,966
Comets may return a long cycle
456
00:22:59,967 --> 00:23:01,501
Almost every thousand years
457
00:23:01,502 --> 00:23:02,533
Or even every million years
458
00:23:02,534 --> 00:23:04,102
Unlike short-comets comets
459
00:23:04,103 --> 00:23:06,037
Which come in circles
460
00:23:06,038 --> 00:23:08,239
Long comets come in rotary orbits
461
00:23:08,240 --> 00:23:09,609
They can come
462
00:23:09,610 --> 00:23:12,111
From everywhere and from different directions
463
00:23:14,014 --> 00:23:18,819
This tells us that they come from a different place
464
00:23:21,621 --> 00:23:24,188
We think the comets are long cycle come from place
465
00:23:24,189 --> 00:23:25,824
,Too far
466
00:23:25,825 --> 00:23:27,825
It is very much like a spherical cloud
467
00:23:27,826 --> 00:23:29,829
For things too far away
468
00:23:29,830 --> 00:23:33,966
Which rush towards the sun all the time
469
00:23:33,967 --> 00:23:36,770
When the culprit approaches, the sun warms it up
470
00:23:36,771 --> 00:23:40,406
The ice turns to gas, and the comet loses a mass
471
00:23:40,407 --> 00:23:43,108
Over time, those comets will disappear
472
00:23:43,109 --> 00:23:44,778
But it continues to come
473
00:23:44,779 --> 00:23:47,581
This confirms her stock there
474
00:23:49,015 --> 00:23:52,784
But where is there?
Where do you come from?
475
00:23:52,785 --> 00:23:54,920
One of the explanations of these strange comets
476
00:23:54,921 --> 00:23:57,422
It's probably not our solar system
477
00:23:57,423 --> 00:23:59,958
The galaxy may be filled with snow
478
00:23:59,959 --> 00:24:02,093
Which sometimes flows on us
479
00:24:02,094 --> 00:24:03,495
Then we thought
480
00:24:03,496 --> 00:24:06,532
They probably come from another part of the solar system
481
00:24:06,533 --> 00:24:10,235
Perhaps our solar system is surrounded
482
00:24:10,236 --> 00:24:12,138
A reel of waste
483
00:24:12,139 --> 00:24:15,107
... from the early days of its formation
484
00:24:15,108 --> 00:24:17,176
"Ort cloud"
485
00:24:17,177 --> 00:24:20,379
It has been assumed to have a stock
486
00:24:20,380 --> 00:24:23,282
A huge cloud surrounds the solar system in millions
487
00:24:23,283 --> 00:24:27,419
Billions, or even trillions of those snow bodies
488
00:24:27,420 --> 00:24:30,856
But we never saw it
489
00:24:30,857 --> 00:24:32,024
Ort cloud
490
00:24:32,025 --> 00:24:34,793
This is the default group
Of comets, are those objects
491
00:24:34,794 --> 00:24:35,660
It's virtual
492
00:24:35,661 --> 00:24:37,896
Not observed at all
493
00:24:37,897 --> 00:24:40,331
The bodies in the Ort cloud are very far away
494
00:24:40,332 --> 00:24:41,499
Small and very dim
495
00:24:41,500 --> 00:24:43,467
So that we never noticed anything
496
00:24:43,468 --> 00:24:45,070
There is in the Ort cloud
497
00:24:45,071 --> 00:24:47,106
Something must fall
498
00:24:47,107 --> 00:24:48,540
To see things fall
499
00:24:48,541 --> 00:24:50,476
Of all those different angles
500
00:24:50,477 --> 00:24:54,415
From there, you can figure out what is there
501
00:24:56,883 --> 00:25:01,320
But the aggregation of huge numbers to build the Ort cloud
502
00:25:01,321 --> 00:25:03,956
Is a very difficult task
503
00:25:03,957 --> 00:25:06,958
You need a powerful computer
504
00:25:06,959 --> 00:25:08,996
"Luckily there is Kevin Walsh
505
00:25:11,497 --> 00:25:14,100
We are here in the heart of a modern supercomputer
506
00:25:14,101 --> 00:25:16,334
On those pregnant thousands of processors
507
00:25:16,335 --> 00:25:18,838
Working day and night to analyze computer models
508
00:25:18,839 --> 00:25:21,308
To understand the evolution of our solar system
509
00:25:21,309 --> 00:25:23,142
And what is there in the edge
510
00:25:24,410 --> 00:25:27,245
"Here's the supercomputer" Janus
511
00:25:27,246 --> 00:25:29,549
"In" Boulder - Colorado
512
00:25:29,550 --> 00:25:31,483
In supercomputers like this
513
00:25:31,484 --> 00:25:33,851
There are thousands of processors
514
00:25:33,852 --> 00:25:36,354
Tens of thousands of competing nuclei
515
00:25:36,355 --> 00:25:39,190
You can do more than
One hundred trillion accounts per second
516
00:25:39,191 --> 00:25:41,127
In such a machine
517
00:25:41,128 --> 00:25:42,328
We need this
518
00:25:42,329 --> 00:25:44,629
If we want to try to understand the evolution
519
00:25:44,630 --> 00:25:47,166
Hundreds of millions of comets over billions of years
520
00:25:47,167 --> 00:25:48,801
Compare what I can do with a paper
521
00:25:48,802 --> 00:25:50,504
There is no comparison
522
00:25:54,200 --> 00:25:56,168
Using a super computer
523
00:25:56,169 --> 00:25:59,805
Astronomers can start assembling an image
524
00:25:59,806 --> 00:26:02,540
Of the large invisible cloud
525
00:26:02,541 --> 00:26:05,643
... and start with what we can see
526
00:26:05,644 --> 00:26:08,147
Comets that rush toward the sun
527
00:26:08,148 --> 00:26:11,284
We will not see the Ort cloud unless a guilty person comes
528
00:26:11,285 --> 00:26:16,790
So we need to estimate times
One comes right
529
00:26:14,121 --> 00:26:16,790
530
00:26:16,791 --> 00:26:19,123
Which will make it pass close to the sun
531
00:26:19,124 --> 00:26:20,526
We can observe it
532
00:26:20,527 --> 00:26:22,795
, We can then reverse and say
533
00:26:22,796 --> 00:26:26,265
We see one in ten "
"Years of about the same size
534
00:26:26,266 --> 00:26:29,301
Then we say, "For this, there must be billions
535
00:26:29,302 --> 00:26:32,371
"And billions of them make the cloud of Ort
536
00:26:32,372 --> 00:26:37,075
Accounts show that the Ort cloud
537
00:26:37,076 --> 00:26:40,412
It hosts up to a trillion of ice
538
00:26:40,413 --> 00:26:44,117
Stretching very far from the edge of the solar field
539
00:26:45,652 --> 00:26:47,120
Hard to calculate
540
00:26:47,121 --> 00:26:50,389
Extent of the Ort cloud
541
00:26:50,390 --> 00:26:52,824
But perhaps its edge
542
00:26:52,825 --> 00:26:57,028
Beyond the sun ten thousand
Time from the Earth's distance to the sun
543
00:26:57,029 --> 00:27:01,867
Trillion miles .. one followed by twelve zero
544
00:27:01,868 --> 00:27:04,436
It is very huge ... very vast ... much wider
545
00:27:04,437 --> 00:27:06,572
, Of the solar planetary system
546
00:27:06,573 --> 00:27:09,676
So that if you remove all the planets from the sun
547
00:27:09,677 --> 00:27:12,078
Will not be affected until the Ort cloud
548
00:27:12,079 --> 00:27:13,711
How exactly
549
00:27:13,712 --> 00:27:16,449
Do the snowy clouds come here?
550
00:27:16,450 --> 00:27:18,382
A comic way of thinking about the Ort cloud
551
00:27:18,383 --> 00:27:21,754
They are the parts of the planets that are never used
552
00:27:21,755 --> 00:27:23,522
It's already wasteful
553
00:27:23,523 --> 00:27:26,726
The Ort cloud did not come as an original
554
00:27:26,727 --> 00:27:27,759
If true
555
00:27:27,760 --> 00:27:30,028
The Ort cloud formed when they tried
556
00:27:30,029 --> 00:27:32,730
But they failed to enroll in training
557
00:27:32,731 --> 00:27:34,766
To become giant planets
558
00:27:34,767 --> 00:27:37,236
In contrast, it was thrown in all directions
559
00:27:37,237 --> 00:27:39,438
It is now halfway to the next star
560
00:27:39,439 --> 00:27:41,140
It is a giant spherical spread
561
00:27:41,141 --> 00:27:46,845
4.6 billion years ago, our sun lit up
562
00:27:46,846 --> 00:27:51,182
A cloud of dust and gas revolves around the newborn star
563
00:27:51,183 --> 00:27:53,286
Then gravity began to work
564
00:27:53,287 --> 00:27:56,288
Attracts gas, dust, ice and rocks
565
00:27:56,289 --> 00:27:59,290
To be the nascent planets
566
00:27:59,291 --> 00:28:01,727
The planets formed from structural units
567
00:28:01,728 --> 00:28:03,129
... smaller parts of materials
568
00:28:03,130 --> 00:28:07,132
Rocks and ice
569
00:28:07,133 --> 00:28:09,067
Materials have come together over time
570
00:28:10,103 --> 00:28:12,805
Rampage of rotating materials
571
00:28:12,806 --> 00:28:17,008
Behind the remains on the body
Rocky ruins in the asteroid belt
572
00:28:17,009 --> 00:28:19,911
Ice in the Quiber belt
573
00:28:19,912 --> 00:28:22,980
Then Neptune and Uranus participated in the event
574
00:28:22,981 --> 00:28:25,051
Lenathan rubble farther away
575
00:28:25,052 --> 00:28:27,119
But think about what happened
576
00:28:27,120 --> 00:28:29,254
... when there are bodies falling together
577
00:28:29,255 --> 00:28:32,425
All kinds of small rocks under the influence of gravity
578
00:28:32,426 --> 00:28:35,760
Some will push around the planet
579
00:28:35,761 --> 00:28:37,562
The space is tossed away
580
00:28:37,563 --> 00:28:40,233
Most of them were thrown out of the solar system forever
581
00:28:40,234 --> 00:28:41,533
Which did not happen to it
582
00:28:41,534 --> 00:28:44,336
Continued in those circular orbits
A million miles long
583
00:28:44,337 --> 00:28:46,171
This is the Ort cloud
584
00:28:46,172 --> 00:28:47,905
Billions of snow rocks
585
00:28:47,906 --> 00:28:49,909
It was tossed in all directions
586
00:28:49,910 --> 00:28:55,514
Until it formed a ball of snakes
Around the entire solar system
587
00:28:55,515 --> 00:28:56,715
Orbit cloud comets
588
00:28:56,716 --> 00:28:58,752
Are the bones of the dinosaurs to form the solar system
589
00:28:58,753 --> 00:29:00,853
Contains ingredients
590
00:29:00,854 --> 00:29:02,755
Which met to form planets
591
00:29:02,756 --> 00:29:05,457
It is a time capsule than the solar system
592
00:29:05,458 --> 00:29:09,027
4.5 billion years ago
593
00:29:09,028 --> 00:29:11,162
Most of the Ort cloud
594
00:29:11,163 --> 00:29:13,431
You will stay in this snowy cloud forever
595
00:29:13,432 --> 00:29:15,834
It revolves around the distant sun
596
00:29:15,835 --> 00:29:18,069
But some will fail
597
00:29:18,070 --> 00:29:23,775
Attracted by the sun's gravity
Inwardly as furniture is attracted by glare
598
00:29:23,776 --> 00:29:25,478
A guilty person may sneak into you
599
00:29:25,479 --> 00:29:26,979
Without even knowing its existence
600
00:29:36,722 --> 00:29:38,757
These comets may be several miles wide
601
00:29:38,758 --> 00:29:41,059
It moves very fast
602
00:29:41,060 --> 00:29:43,628
Sometimes even a hundred miles per second
603
00:29:43,629 --> 00:29:45,732
This makes them very dangerous
604
00:29:45,733 --> 00:29:48,468
How serious is it?
Ask Dinosaura
605
00:29:50,169 --> 00:29:52,604
Some people believe that a huge collision
606
00:29:52,605 --> 00:29:53,972
Who wiped dinosaurs
607
00:29:53,973 --> 00:29:58,244
Perhaps caused by a huge comet of Ort cloud
608
00:30:01,413 --> 00:30:04,048
It can be dangerous
609
00:30:04,049 --> 00:30:07,552
Like asteroids that we considered
Responsible for the extinction of the earth
610
00:30:07,553 --> 00:30:10,555
Comets fall from a very distant place
611
00:30:10,556 --> 00:30:12,790
So it moves faster than asteroids
612
00:30:12,791 --> 00:30:15,494
This is why their collisions are larger
613
00:30:17,130 --> 00:30:19,898
Even if a small particle displays a mile or two
614
00:30:19,899 --> 00:30:22,101
It may cause a lot of destruction
615
00:30:22,102 --> 00:30:23,803
But many of the Ort cloud comets
616
00:30:23,804 --> 00:30:26,171
Which come to the inner solar system is very huge
617
00:30:26,172 --> 00:30:28,739
Imagine if he were one of them
618
00:30:28,740 --> 00:30:32,778
With a width of thirty or fifty miles, it will be a global disaster
619
00:30:36,415 --> 00:30:39,116
We have no warning
620
00:30:39,117 --> 00:30:40,919
Because we have no idea
621
00:30:40,920 --> 00:30:45,025
For the substance that is thrown from the cloud Ort us
622
00:30:47,160 --> 00:30:49,761
Our enemy may be remote
623
00:30:49,762 --> 00:30:53,265
The biggest secrets of the solar system
624
00:30:53,266 --> 00:30:55,933
A wicked twin of our sun
625
00:30:55,934 --> 00:31:00,139
... a second star within our solar system
626
00:31:00,140 --> 00:31:02,342
"Nemesis" = "our enemy"
627
00:31:09,800 --> 00:31:11,969
We have updated our virtual knowledge
628
00:31:11,970 --> 00:31:13,302
Of the solar system
629
00:31:13,303 --> 00:31:16,339
To about 9 trillion miles after the planets
630
00:31:16,340 --> 00:31:19,675
But we are still working in the dark
631
00:31:19,676 --> 00:31:22,212
"Carl Sagan said." We are in the Magellanic era
632
00:31:22,213 --> 00:31:24,013
"We are not in the era of Columbus"
633
00:31:24,014 --> 00:31:25,182
What does this mean?
634
00:31:25,183 --> 00:31:26,916
I mean we know the basic parameters
635
00:31:26,917 --> 00:31:28,719
, For our solar system
We know the planets
636
00:31:28,720 --> 00:31:30,788
We know of the Kuiper belt and the Ort cloud
637
00:31:30,789 --> 00:31:32,155
But we do not know the details
638
00:31:32,156 --> 00:31:34,592
We did not actually visit one of those places
639
00:31:34,593 --> 00:31:36,061
We do not know geography
640
00:31:36,062 --> 00:31:38,394
So we are currently filling the map
641
00:31:38,395 --> 00:31:39,997
We have developed
642
00:31:39,998 --> 00:31:43,467
, The presence of about two trillion in the Ort cloud
643
00:31:43,468 --> 00:31:46,103
A ball of waste
644
00:31:46,104 --> 00:31:47,805
, Of the composition of the solar system
645
00:31:47,806 --> 00:31:49,673
And occasionally
646
00:31:49,674 --> 00:31:53,876
One of these objects drips on us
647
00:31:53,877 --> 00:31:58,682
The important question is, why does one decide to come suddenly?
648
00:31:58,683 --> 00:31:59,817
What worries her?
649
00:31:59,818 --> 00:32:01,685
What drives them to fall
650
00:32:01,686 --> 00:32:03,620
And approach the inner solar system?
651
00:32:03,621 --> 00:32:04,956
There are so many different ideas
652
00:32:04,957 --> 00:32:06,289
For that reason
653
00:32:06,290 --> 00:32:09,760
Some found signs of a series of disasters
654
00:32:09,761 --> 00:32:11,929
Which virtually wiped out life on Earth
655
00:32:11,930 --> 00:32:14,765
The fossil record appeared in the presence
656
00:32:14,766 --> 00:32:17,433
Periodic series of mass extinctions
657
00:32:17,434 --> 00:32:19,804
Every 26 million years
658
00:32:19,805 --> 00:32:21,806
It seems to be something
659
00:32:21,807 --> 00:32:26,176
He was hit by a cloud of Ort
Periodically dispersing comets
660
00:32:26,177 --> 00:32:28,744
Which opens up fierce prospects
661
00:32:28,745 --> 00:32:30,146
When we look at the stars
662
00:32:30,147 --> 00:32:33,083
Note that most of them are in pairs
663
00:32:33,084 --> 00:32:35,786
Sometimes they may be
Very far apart
664
00:32:35,787 --> 00:32:38,323
It may take up to millions
Years to turn around
665
00:32:38,324 --> 00:32:40,523
So the question seems normal
666
00:32:40,524 --> 00:32:42,092
The sun is a companion
667
00:32:42,093 --> 00:32:45,895
Did not we discover some for his distance?
668
00:32:45,896 --> 00:32:48,097
It is amazing to think that to the sun
669
00:32:48,098 --> 00:32:49,933
Brother or sister at the moment
670
00:32:49,934 --> 00:32:52,603
Because we know that more
Of half the stars in our galaxy
671
00:32:52,604 --> 00:32:53,904
-100 billion stars-
672
00:32:53,905 --> 00:32:56,473
In binary, triple or quadruple systems
673
00:32:56,474 --> 00:32:59,076
So the only star is an exception
674
00:32:59,077 --> 00:33:02,645
Is this distant star responsible
675
00:33:02,646 --> 00:33:05,147
About Ort cloud cloud?
676
00:33:05,148 --> 00:33:08,019
What may have happened is that every 26 million years
677
00:33:08,020 --> 00:33:11,622
This partner star crosses the Ort cloud
678
00:33:11,623 --> 00:33:13,289
The orbits are down
679
00:33:13,290 --> 00:33:15,424
Comets are pushed in all directions
680
00:33:15,425 --> 00:33:18,028
Some come to the inner solar system
681
00:33:18,029 --> 00:33:21,165
It hits the ground and causes collective destruction
682
00:33:24,235 --> 00:33:28,638
The name of this dangerous double star
683
00:33:28,639 --> 00:33:30,640
"Sun partner is" Nemesis
684
00:33:35,747 --> 00:33:38,417
Nemesis has its problems
685
00:33:38,418 --> 00:33:41,550
The attraction of the mysterious star that you are sure
686
00:33:41,551 --> 00:33:43,186
By passing the Ort cloud
687
00:33:43,187 --> 00:33:45,088
Comets may be sent periodically
688
00:33:45,089 --> 00:33:47,692
Rushing towards the sun and the earth
689
00:33:47,693 --> 00:33:51,760
But if the sun had a companion star
690
00:33:51,761 --> 00:33:54,131
It should be easily visible
691
00:33:54,132 --> 00:33:56,732
"You think if that star" Nemesis
692
00:33:56,733 --> 00:33:58,202
It should be visible
693
00:33:58,203 --> 00:33:59,469
Stars are of course bright
694
00:33:59,470 --> 00:34:02,739
But the theory here is that Nemesis is a dwarf star
695
00:34:02,740 --> 00:34:04,240
Maybe he's a brown dwarf
696
00:34:04,241 --> 00:34:05,942
It will be very small
697
00:34:05,943 --> 00:34:08,913
That is why it is hardly bright
698
00:34:10,081 --> 00:34:13,783
The brown dwarf is not a star or a planet
699
00:34:13,784 --> 00:34:15,285
It's something between them
700
00:34:15,286 --> 00:34:19,356
A lean star never lighted
701
00:34:19,357 --> 00:34:21,758
The stars light up when gravity is crushed
702
00:34:21,759 --> 00:34:24,395
Pull the vast hydrogen gas together
703
00:34:24,396 --> 00:34:27,231
High pressures and temperatures are generated
704
00:34:27,232 --> 00:34:29,531
If there is not enough gas
705
00:34:29,532 --> 00:34:33,437
There will not be enough gravity to ignite a nuclear fire
706
00:34:33,438 --> 00:34:34,738
He did not become a star
707
00:34:34,739 --> 00:34:37,040
On the other hand, it is bigger than the buyer
708
00:34:37,041 --> 00:34:40,944
One on a thousandth of the mass of the sun
709
00:34:40,945 --> 00:34:45,749
These things are heating up
But does not explode like the star does
710
00:34:45,750 --> 00:34:48,250
It is hard to see because it is too dark
711
00:34:48,251 --> 00:34:52,221
But may contain a large block
712
00:34:52,222 --> 00:34:55,258
There is a dwarf built somewhere in there
713
00:34:55,259 --> 00:34:59,028
Comets drive us in equal intervals?
714
00:34:59,029 --> 00:35:03,399
The brown dwarf run for these
The degree will be blind to us to see
715
00:35:03,400 --> 00:35:07,604
But it will be hot enough
We can find it using infrared
716
00:35:07,605 --> 00:35:08,906
With infrared telescopes
717
00:35:08,907 --> 00:35:10,874
Heat can capture something
718
00:35:10,875 --> 00:35:12,776
Even if it does not send a light
719
00:35:12,777 --> 00:35:14,678
Something like brown dwarf
720
00:35:14,679 --> 00:35:17,513
Even if it does not glow with visible light
721
00:35:17,514 --> 00:35:19,348
It must produce heat
722
00:35:19,349 --> 00:35:23,720
There are always flights that wipe the entire sky
723
00:35:23,721 --> 00:35:27,024
If there were a dwarf aged four billion years
724
00:35:27,025 --> 00:35:30,127
Somewhere near the sun you will be spotted
725
00:35:30,128 --> 00:35:32,828
"So far, Nemesis has not been found
726
00:35:32,829 --> 00:35:35,832
If there was no star "Nemesis" there
727
00:35:35,833 --> 00:35:38,602
Is there anything else that messes with the Ort cloud?
728
00:35:38,603 --> 00:35:42,506
Another theory assumes a relatively large planet
729
00:35:42,507 --> 00:35:46,944
The size of the earth, for example
It runs far behind Neptune
730
00:35:46,945 --> 00:35:48,946
But monitoring a planet with this dimension
731
00:35:48,947 --> 00:35:53,015
Harder than monitoring a dwarf star
732
00:35:53,016 --> 00:35:56,086
The farther the planet was from the sun, the darker it was
733
00:35:56,087 --> 00:35:57,655
And more difficult to see
734
00:35:57,656 --> 00:36:00,790
So there may be a planet the size of the earth
735
00:36:00,791 --> 00:36:03,459
The sun is several billion miles away
736
00:36:03,460 --> 00:36:06,597
It will be invisible to our current encounters
737
00:36:11,603 --> 00:36:15,372
There is still an opportunity to have something the size of the earth
738
00:36:15,373 --> 00:36:16,774
, Away in the Ort cloud
739
00:36:16,775 --> 00:36:18,443
He moves the bodies
740
00:36:19,978 --> 00:36:23,747
"This was the last nail in the coffin of Nimes' theory
741
00:36:23,748 --> 00:36:27,183
We may never know what to say
742
00:36:27,184 --> 00:36:29,685
Ort cloud objects from orbit
743
00:36:29,686 --> 00:36:32,022
But it's not the only one there
744
00:36:34,159 --> 00:36:37,394
We still do not know where the solar system ends
745
00:36:37,395 --> 00:36:39,062
Search for the edge of the solar system
746
00:36:39,063 --> 00:36:40,930
Helps us with a bigger problem
747
00:36:40,931 --> 00:36:42,899
To understand the entire solar system
748
00:36:42,900 --> 00:36:45,135
How do you realize the whole solar system
749
00:36:45,136 --> 00:36:46,970
Without revealing his edge?
750
00:36:46,971 --> 00:36:50,307
Probably the biggest puzzle ever
751
00:36:50,308 --> 00:36:53,209
That our sun has many particles
752
00:36:53,210 --> 00:36:56,747
It roams the universe more than its fair share
753
00:36:56,748 --> 00:36:59,549
Probably because our sun is a thief
754
00:36:59,550 --> 00:37:04,687
She stole her sisters and brothers in the womb of the universe
755
00:37:04,688 --> 00:37:07,658
But those extra particles
May be our ticket to get out
756
00:37:07,659 --> 00:37:11,229
When the sun turns the heat on us
757
00:37:19,270 --> 00:37:20,602
25 years ago
758
00:37:20,603 --> 00:37:22,640
The solar system had nine planets in front of our eyes
759
00:37:22,641 --> 00:37:26,010
It is seven billion miles wide
760
00:37:26,011 --> 00:37:29,245
We now know that it is a thousand times bigger
761
00:37:29,246 --> 00:37:31,580
And display more than three light years
762
00:37:31,581 --> 00:37:36,386
The more we look at it, the more it expands
763
00:37:36,387 --> 00:37:39,089
It expands greatly
764
00:37:39,090 --> 00:37:43,959
Somehow we took our order
Solar materials too much
765
00:37:43,960 --> 00:37:47,531
Theoretically, we can calculate the number of comets that have been formed
766
00:37:47,532 --> 00:37:49,866
When the solar system itself
767
00:37:49,867 --> 00:37:51,468
Then we can look
768
00:37:51,469 --> 00:37:52,998
To the number of comets coming from the Ort cloud
769
00:37:52,999 --> 00:37:55,104
We try to find out who is actually there
770
00:37:55,105 --> 00:37:57,240
It is clear that the two figures are quite far apart
771
00:37:57,241 --> 00:37:59,508
The number of comets formed with the sun
772
00:37:59,509 --> 00:38:01,144
Much less
773
00:38:01,145 --> 00:38:03,879
Of the number of comets that we find there
774
00:38:03,880 --> 00:38:07,283
There is a huge amount of material in the Ort cloud
775
00:38:07,284 --> 00:38:11,388
To belong to one medium size star
776
00:38:11,389 --> 00:38:14,959
The only way to balance
Two digits if the sun
777
00:38:14,960 --> 00:38:17,627
Thief when she was formed
778
00:38:17,628 --> 00:38:20,997
Five billion years ago
779
00:38:20,998 --> 00:38:25,002
A great storm burst, sending a shock wave
780
00:38:25,003 --> 00:38:27,770
Across a huge cloud of dust and gas
781
00:38:27,771 --> 00:38:32,107
She pressed the cloud
.. Producing zones of dense gas
782
00:38:32,108 --> 00:38:34,310
Star Nursery
783
00:38:34,311 --> 00:38:36,479
Hundreds of pockets of gases are compressed
784
00:38:36,480 --> 00:38:37,914
Under its appeal
785
00:38:37,915 --> 00:38:43,352
To be hundreds of sister stars
786
00:38:43,353 --> 00:38:44,453
We believe that the sun has formed
787
00:38:44,454 --> 00:38:46,289
With brothers and sisters in clusters
788
00:38:46,290 --> 00:38:48,857
We believe that the sun has formed in a cluster
789
00:38:48,858 --> 00:38:50,493
With 400 or 500 other stars
790
00:38:50,494 --> 00:38:52,461
If we could picture the composition of those stars
791
00:38:52,462 --> 00:38:55,330
They are very small compared to the distance between them
792
00:38:55,331 --> 00:38:57,566
But its cloud of comets is very large
793
00:38:57,567 --> 00:39:01,671
So comets can be stolen from them
794
00:39:01,672 --> 00:39:04,573
, The sun was smart
She walked away when she was at the front
795
00:39:04,574 --> 00:39:06,475
I got a bunch of comets from other stars
796
00:39:06,476 --> 00:39:09,278
Then she went on her way
797
00:39:09,279 --> 00:39:12,115
Some of the objects that are now around us from afar
798
00:39:12,116 --> 00:39:14,684
She may have come from those other young stars
799
00:39:15,000 --> 00:39:16,836
Competing global brothers
800
00:39:16,837 --> 00:39:18,671
It may still be happening now
801
00:39:18,672 --> 00:39:22,175
We may steal the bodies of our brothers and sisters
802
00:39:22,176 --> 00:39:26,377
While deviating from the cloud of our Ort
803
00:39:26,378 --> 00:39:28,646
The nearest star is the Ort cloud
804
00:39:28,647 --> 00:39:29,548
Against the solar system
805
00:39:29,549 --> 00:39:30,682
The Centaur Man
806
00:39:30,683 --> 00:39:32,917
There may be another Ort cloud
807
00:39:32,918 --> 00:39:34,287
About the centaur man
808
00:39:34,288 --> 00:39:36,153
There may be objects interchangeable
809
00:39:36,154 --> 00:39:37,455
Between the two stars
810
00:39:37,456 --> 00:39:40,892
Midway between these two stars we found
811
00:39:40,893 --> 00:39:42,961
The true edge of our solar system
812
00:39:42,962 --> 00:39:45,729
And what happens at the edge
813
00:39:45,730 --> 00:39:48,667
It may be bad news for us
814
00:39:48,668 --> 00:39:51,002
It may be for the centaur man
Effect on life here on earth
815
00:39:51,003 --> 00:39:54,006
Perhaps this star has particles around it
816
00:39:54,007 --> 00:39:56,742
In the Ort cloud its effect is attractive
817
00:39:56,743 --> 00:39:57,910
On our Ort cloud
818
00:39:57,911 --> 00:40:00,646
When something falls, it may be a result
819
00:40:00,647 --> 00:40:02,881
The effect of our nearest star
820
00:40:02,882 --> 00:40:05,850
This means it is not an edge
821
00:40:05,851 --> 00:40:08,720
Tightening and attracting not only infinite
822
00:40:08,721 --> 00:40:12,858
We humans like the edges of the separator like the border
823
00:40:12,859 --> 00:40:14,859
But the solar system is not
824
00:40:14,860 --> 00:40:17,329
It is fading
825
00:40:17,330 --> 00:40:20,798
It mixes in the galaxy as a whole
826
00:40:20,799 --> 00:40:23,934
, The sun does not live alone
As well as our Ort cloud
827
00:40:23,935 --> 00:40:26,303
We interact constantly, in this way
828
00:40:26,304 --> 00:40:28,539
We are linked to a larger environment
829
00:40:28,540 --> 00:40:30,209
Milky Way
830
00:40:30,210 --> 00:40:33,111
This mystery may remind us
831
00:40:33,112 --> 00:40:35,613
Out of the solar system
832
00:40:35,614 --> 00:40:37,883
When the solar system ends
833
00:40:37,884 --> 00:40:40,818
There may be an end to the outside
834
00:40:40,819 --> 00:40:43,856
And the beginning of a new journey
835
00:40:47,092 --> 00:40:49,760
One of the fun things about knowing
836
00:40:49,761 --> 00:40:52,196
Install our solar system
837
00:40:52,197 --> 00:40:54,733
There are lots of other objects
838
00:40:54,734 --> 00:40:56,968
Which we can use as resources
839
00:40:56,969 --> 00:41:00,305
We go out into interstellar space
840
00:41:00,306 --> 00:41:02,742
There are rocks, there is ice
841
00:41:02,743 --> 00:41:05,843
Maybe we can refuel
Our space vehicle when we pass
842
00:41:05,844 --> 00:41:08,180
Perhaps something as distant and fluffy as the Ort cloud
843
00:41:08,181 --> 00:41:10,749
Be our next trip
844
00:41:10,750 --> 00:41:13,954
Let's actually explore the galaxy
845
00:41:19,759 --> 00:41:22,560
We have a lot to learn about the solar system
846
00:41:22,561 --> 00:41:25,897
With many new surprises to explore
847
00:41:25,898 --> 00:41:28,367
Each time we open a new window on the universe
848
00:41:28,368 --> 00:41:30,468
We are surprised, and that's what excites me
849
00:41:30,469 --> 00:41:33,338
I wake up every morning and am surprised if I am not surprised
850
00:41:33,339 --> 00:41:36,140
And by opening up new technologies
851
00:41:36,141 --> 00:41:39,510
Our understanding of what is there also opens
852
00:41:39,511 --> 00:41:41,146
We build better platforms
853
00:41:41,147 --> 00:41:42,881
We send probes to space
854
00:41:42,882 --> 00:41:44,415
We have a lot to learn
855
00:41:44,416 --> 00:41:46,318
This is a really exciting part
856
00:41:46,319 --> 00:41:48,352
Our new eyes of the universe
857
00:41:48,353 --> 00:41:51,990
Show our solar system in a completely new window
858
00:41:51,991 --> 00:41:56,160
We are slowly gathering complex links
859
00:41:56,161 --> 00:42:01,798
Which connects it to our lives and to the color behind them
860
00:42:01,799 --> 00:42:05,069
Every discovery we do about the universe tells us
861
00:42:05,070 --> 00:42:06,772
There is no solar system like an island
862
00:42:06,773 --> 00:42:10,010
So that the materials come from outside and come inside
863
00:42:10,011 --> 00:42:11,843
And graduated from the inside out
864
00:42:11,844 --> 00:42:15,046
And when we gnaw at the outer edges of our solar system
865
00:42:15,047 --> 00:42:19,184
We change what we mean by the solar system
866
00:42:19,185 --> 00:42:21,785
We are taking the first steps outside the planet
867
00:42:21,786 --> 00:42:23,722
And start looking at our environment
868
00:42:23,723 --> 00:42:24,958
This is very structured
869
00:42:26,159 --> 00:42:28,794
The sun is like one voice
870
00:42:28,795 --> 00:42:32,263
In a large chorus of hundreds of billions of other stars
871
00:42:32,264 --> 00:42:34,600
And their own solar systems
872
00:42:35,902 --> 00:42:38,470
I find it emotionally true
873
00:42:38,471 --> 00:42:43,608
We are part of the larger population there
874
00:42:43,609 --> 00:42:47,211
To believe we found everything in our solar system
875
00:42:47,212 --> 00:42:50,015
And the assumption that we know everything
This is not the way science works
876
00:42:50,016 --> 00:42:53,184
The science of pushing boundaries
877
00:42:53,185 --> 00:42:54,685
We continue to do so
878
00:42:54,686 --> 00:42:57,421
In ten years, if we did this program again
879
00:42:57,422 --> 00:43:00,793
I would not be surprised if we talked about new things
66798
