284 00:24:41,990 --> 00:24:50,636 Scientists in the last decade have observed hundreds of stars The individual races through our galaxy like a ballistic missile 285 00:24:50,836 --> 00:24:54,703 Scientists launched these electrolytes 286 00:24:54,703 --> 00:24:58,218 They travel at incredible speeds 287 00:24:58,418 --> 00:25:03,936 We talk about stars a thousand times faster than the rocket 288 00:25:04,136 --> 00:25:10,693 Anything super fast is dangerous Superstar is very dangerous 289 00:25:10,893 --> 00:25:17,774 A ball of hot gas shows millions Mileage trickles into our cosmic neighborhood 290 00:25:19,288 --> 00:25:24,288 You don't need the runaway stars For direct injuries until damage occurs 291 00:25:24,488 --> 00:25:31,380 Even at the maximum extent of our system The sun has enough to destroy the Earth 292 00:25:31,580 --> 00:25:35,172 Don't want to get close to a star Many of us under any circumstances 293 00:25:35,172 --> 00:25:38,001 Because this can disrupt the orbits of planets 294 00:25:38,001 --> 00:25:42,949 The passing star does not need to come closer Too much to cause serious damage 295 00:25:42,949 --> 00:25:47,801 We have a huge Ort cloud of comets Which takes two light years away from the sun 296 00:25:48,001 --> 00:25:53,842 If a star passes by, we will be hit by devastating comets 297 00:25:55,490 --> 00:26:03,686 All planets in the solar system Torn or burned into the star 298 00:26:03,686 --> 00:26:07,273 I don't expect the solar system to survive 299 00:26:07,473 --> 00:26:11,628 Astronomers follow the paths of fugitive stars 300 00:26:11,828 --> 00:26:16,930 They found that most came from the centers of galaxies 301 00:26:18,583 --> 00:26:23,365 In the middle of our galaxy, we see stars Confined to orbit around a central black hole 302 00:26:23,565 --> 00:26:26,685 As if it were a circle like an angry hive 303 00:26:26,885 --> 00:26:34,220 These stars interact with each other Sometimes they are played by the galaxy 304 00:26:34,420 --> 00:26:37,761 Most runaway stars are harmless to us 305 00:26:37,961 --> 00:26:41,912 Leave the space of the Hungarian center 306 00:26:42,112 --> 00:26:47,475 But from time to time we see fugitives nearby 307 00:26:48,573 --> 00:26:55,636 In 2016, astronomers paid attention to Shard's star Just 3,000 light years away from Earth 308 00:26:57,519 --> 00:27:02,544 The path and composition of the star are illogical 309 00:27:02,744 --> 00:27:07,885 There is a star "SDSS C 1128", it's strange 310 00:27:07,885 --> 00:27:12,229 It's strange because it travels very fast through the galaxy 311 00:27:12,229 --> 00:27:15,918 Faster than he could move if he were in orbit 312 00:27:16,118 --> 00:27:17,973 Something threw him hard 313 00:27:18,173 --> 00:27:20,826 But he also has something unusual 314 00:27:21,026 --> 00:27:27,446 It's a star like the sun, but there's a lot of it Carbon, this is unusual 315 00:27:27,646 --> 00:27:32,620 Stars like the sun don't Carbon only at the end of its life cycle 316 00:27:32,620 --> 00:27:36,396 When they swell to become red giants 317 00:27:36,596 --> 00:27:42,523 But he was a carbon-covered star where he should have been To burn hydrogen at this point in your life 318 00:27:42,723 --> 00:27:43,699 What happened there? 319 00:27:45,265 --> 00:27:51,812 Scientists believe the runaway star is rich Carbon May Have Been a Vampire Before 320 00:27:52,012 --> 00:27:59,758 He is trapped in a close bilateral partnership Very fast with super-large star 321 00:27:59,958 --> 00:28:04,147 Vampire sucked the rich gas With carbon from your huge swollen partner 322 00:28:04,347 --> 00:28:07,587 But the superstar was a victim of resistance 323 00:28:07,787 --> 00:28:11,731 It burst forth in a vast and sweeping torrent 324 00:28:11,731 --> 00:28:15,555 You should have held the strength The explosion destroyed the vampire 325 00:28:15,755 --> 00:28:23,491 But his orbital speed was too great, he was thrown This carbon-rich star in space 326 00:28:26,087 --> 00:28:28,753 These were the stars each other very quickly 327 00:28:28,953 --> 00:28:34,344 When one of them exploded, he lost most Its mass is very attractive 328 00:28:34,344 --> 00:28:37,462 He didn't have enough attractiveness To keep the star with the lowest mass 329 00:28:37,662 --> 00:28:43,814 They turned around, one of them exploded The other found himself exuberant outside the galaxy 330 00:28:44,014 --> 00:28:45,263 That explains everything 331 00:28:45,463 --> 00:28:47,450 Carbon obtained from the star with the greatest mass 332 00:28:47,450 --> 00:28:53,088 The star exploded into a large block and expelled the star Small mass for high speed 333 00:28:53,188 --> 00:28:59,763 What are the chances that our planet will burn A star who goes by Vampire? 334 00:29:00,471 --> 00:29:08,115 ,,,in the space of our galaxy Our solar system is a small target 335 00:29:08,315 --> 00:29:12,611 It's rare to get close to two stars Enough to do it 336 00:29:12,811 --> 00:29:20,086 Even during the billions of years he lives The star,,,will not happen in the life of any specific star 337 00:29:24,179 --> 00:29:28,647 It is unlikely to be destroyed Vampire crosses the earth 338 00:29:28,847 --> 00:29:35,438 But there's another kind of deadly star There is a direct and present danger 339 00:29:35,438 --> 00:29:40,729 And we know he can beat us Because he's done this before 340 00:29:56,365 --> 00:29:58,201 March 2008 341 00:29:58,401 --> 00:30:04,382 Astronomers were surprised when they saw Light extinguished across the sky, suddenly appeared 342 00:30:04,382 --> 00:30:08,118 And suddenly disappeared in less than a minute 343 00:30:08,318 --> 00:30:10,338 A rare occurrence of astronomers 344 00:30:10,538 --> 00:30:19,072 But it is a powerful reminder that our planet is connected Fireball is the most powerful type of deadly star in the universe 345 00:30:19,272 --> 00:30:24,258 A supernatural weapon known for gamma ray bursts 346 00:30:24,458 --> 00:30:31,372 Gamma ray radios,radiological weapons Cosmic is the strongest and most powerful weapon in the universe 347 00:30:31,572 --> 00:30:36,614 Gamma ray emissions will not last For a long period of time, but diverted by two minutes 348 00:30:36,814 --> 00:30:39,222 But the energy released at this moment 349 00:30:39,222 --> 00:30:47,251 It is equivalent to 100 trillion nuclear weapons Every second passes 100 billion years 350 00:30:48,792 --> 00:30:54,300 Gamma-ray radios are belts High energy concentrated light 351 00:30:54,500 --> 00:31:00,850 And hit hard enough to evaporate nearby planets 352 00:31:01,050 --> 00:31:05,207 It's like the Great Torch, but More like a supernova 353 00:31:05,407 --> 00:31:10,780 The idea is that, instead of exploding a star ,,,to propagate the fruits in all directions 354 00:31:10,980 --> 00:31:16,535 And if it somehow exploded One direction instead of each direction? 355 00:31:16,535 --> 00:31:23,716 Somehow, it concentrates all the material It's thrown like a blast beam 356 00:31:23,916 --> 00:31:32,277 The main idea here is that we are not talking about anything Explodes like a shaft and spreads its energy in all directions 357 00:31:32,477 --> 00:31:37,830 The gamma ray burst is concentrated and takes All your energy and your point in us 358 00:31:38,030 --> 00:31:42,554 He is directly called to us, as this is very powerful 359 00:31:45,613 --> 00:31:52,269 A gamma-ray burst in 2008 would collide The earth is direct, but it comes from a great distance 360 00:31:52,269 --> 00:31:55,665 Where this superior weapon seemed to have lost its power 361 00:31:55,865 --> 00:31:59,066 Astronomers quickly calculated the origin of the beam 362 00:31:59,266 --> 00:32:03,712 They identified a location on the other side of the universe 363 00:32:04,911 --> 00:32:12,177 That cosmic bullet remained Travels through space for seven billion years 364 00:32:12,377 --> 00:32:15,511 Much more than our solar system 365 00:32:15,711 --> 00:32:17,964 We're talking about something high energy 366 00:32:18,164 --> 00:32:25,396 If you look at it with the naked eye To see it, even though it is seven billion light years away 367 00:32:25,596 --> 00:32:29,038 Can you imagine something? High energy and violent 368 00:32:29,238 --> 00:32:32,624 It appears to be a beautiful starry star in the sky 369 00:32:32,824 --> 00:32:34,527 Think about it for a second 370 00:32:34,727 --> 00:32:41,847 We have something very bright that can be seen with the naked eye Although it is about half the distance of the visible universe 371 00:32:44,036 --> 00:32:45,931 In 2008, we were lucky 372 00:32:46,131 --> 00:32:50,586 If the same gamma ray burst were erased A few thousand light years away 373 00:32:50,586 --> 00:32:54,614 To turn the Earth's surface into a plasma 374 00:32:54,814 --> 00:32:56,563 But we're safe now 375 00:32:56,763 --> 00:33:03,131 These things happen somewhere in the universe every day 376 00:33:03,331 --> 00:33:06,013 Every day, I didn't miss it here 377 00:33:06,013 --> 00:33:09,455 Not every century or a thousand years, but every day 378 00:33:09,455 --> 00:33:13,889 Somewhere in the Balkans and in the hundreds of billions The galaxies that make up our universe 379 00:33:14,089 --> 00:33:21,490 There is a supernova that emits these explosions It burns everything within a few hundred light years 380 00:33:23,196 --> 00:33:27,062 Where does it come from then Explosions that dissolve planets? 381 00:33:27,262 --> 00:33:29,352 And how worried should we be? 382 00:33:29,552 --> 00:33:33,001 What you do is draw a huge star that goes fast 383 00:33:33,201 --> 00:33:37,918 A huge star rotates quickly And burn all your nuclear energy 384 00:33:37,918 --> 00:33:41,000 It has a core of action in the center 385 00:33:41,200 --> 00:33:45,048 This iron pulp becomes non-ferrous Stable and collapses into a neutron star 386 00:33:45,248 --> 00:33:48,066 If the neutron star rotated rapidly 387 00:33:48,266 --> 00:33:54,548 This means that if it turns a thousand times per second It will have a huge amount of cyclic energy 388 00:33:57,250 --> 00:34:05,034 This energy is concentrated when the star shrinks Strong magnetic fields of neutron stars 389 00:34:06,630 --> 00:34:13,439 With nowhere else to go, it explodes The energy is confined to the poles of the neutron star 390 00:34:13,639 --> 00:34:19,090 It makes an emission like Toothpaste tube age 391 00:34:19,290 --> 00:34:22,822 Emission can reach the star in all directions 392 00:34:23,022 --> 00:34:30,106 He prepares a magnetic bomb and then exports it Emissions that destroy the star in one direction 393 00:34:30,106 --> 00:34:32,423 To get out of each pole, pole North and Antarctica 394 00:34:34,822 --> 00:34:40,306 And the amount of energy concentrated in These beams make them death rays 395 00:34:40,306 --> 00:34:45,284 These are the most powerful events That occur in the contemporary universe 396 00:34:48,455 --> 00:34:52,187 What is the probability of direct damage to the land? 397 00:34:52,387 --> 00:34:55,403 The simple answer, I don't know 398 00:34:56,470 --> 00:35:00,137 The problem with gamma ray bursts is that Dangerous place far away 399 00:35:00,337 --> 00:35:05,534 Maybe stars are about to make explosions Gamma rays are aimed at us and we don't know about them 400 00:35:05,734 --> 00:35:09,833 We scan the sky and know The stars we think are serious 401 00:35:10,033 --> 00:35:12,334 We don't seem to look at the gun barrel 402 00:35:12,534 --> 00:35:14,358 Maybe we're safe so far 403 00:35:14,558 --> 00:35:18,717 We don't need to worry about the night To kill us with gamma ray blasts 404 00:35:18,917 --> 00:35:24,427 But the universe is big and old, and that means That strange things always happen 405 00:35:24,627 --> 00:35:29,894 We can destroy our solar system With a gamma ray burst in the future 406 00:35:31,012 --> 00:35:38,136 ,But the universe is spacious, we are small targets This is likely to be in our favor 407 00:35:38,336 --> 00:35:42,706 However, he grabbed Silicon is another deadly killer 408 00:35:42,906 --> 00:35:52,046 They think this star is a bad guy The same killer who will destroy the earth in the end 409 00:36:05,473 --> 00:36:09,681 We now know that our universe is full of deadly stars 410 00:36:09,881 --> 00:36:15,445 We know the existence of a planet Somewhere about to burn 411 00:36:16,606 --> 00:36:23,500 But even recently, our guide to this The Planetary Incubator was indirect 412 00:36:23,500 --> 00:36:27,714 We saw many death stars That burns the planets all the time 413 00:36:27,914 --> 00:36:34,285 We haven't seen any of these planets These stars destroy them just once 414 00:36:34,485 --> 00:36:37,666 It turned out to be a planet like Earth 415 00:36:37,866 --> 00:36:41,514 It was about a star very similar to the sun before 416 00:36:43,710 --> 00:36:44,792 2015 417 00:36:44,992 --> 00:36:49,596 "Scout Astronomers" David Kiping " In statements from Kepler 418 00:36:49,796 --> 00:36:56,752 A telescope designed to monitor planets The Ministry of Foreign Affairs passes by its stars 419 00:36:56,952 --> 00:37:02,837 Your attention draws a white dwarf with an unusual fingerprint 420 00:37:03,037 --> 00:37:06,335 Rather than dim your light with a regular circular planet 421 00:37:06,535 --> 00:37:13,496 The small star appeared surrounded by reptiles Stretched from broken rocks and dust 422 00:37:15,307 --> 00:37:18,683 See from this white ring Many diminish in their shine 423 00:37:18,883 --> 00:37:21,855 Maybe obscure up to 40% of the light 424 00:37:22,055 --> 00:37:26,467 In some spacing periods, however All in about five hours 425 00:37:26,667 --> 00:37:31,979 What does the rotation of nearby things mean? Record and in a grouped group 426 00:37:33,139 --> 00:37:35,606 What might these aggregate groups be? 427 00:37:35,606 --> 00:37:38,294 It is too dense to be a group of asteroids 428 00:37:38,494 --> 00:37:42,564 And too close to their star to be comets 429 00:37:42,764 --> 00:37:48,572 Our best explanation was that it was not a planet Solo revolves around this white dwarf 430 00:37:48,772 --> 00:37:54,472 But miniature planets, perhaps the product of a destroyed planet 431 00:37:55,720 --> 00:38:01,756 The white dwarf was caught in the act of killing its planet 432 00:38:01,956 --> 00:38:05,214 It is a very close planet From this white ring 433 00:38:05,214 --> 00:38:11,121 Tidal forces were created The white dwarf that separates the planet 434 00:38:11,321 --> 00:38:15,457 Now we see autumn fallow On the surface of the white dwarf 435 00:38:15,657 --> 00:38:23,490 It was a good discovery, I mean our expectation came true But to see direct evidence from the eye 436 00:38:23,490 --> 00:38:32,392 I mean, seeing a planet crash in front of you was Confirmation of something we have long anticipated 437 00:38:34,172 --> 00:38:37,745 We just saw a star kill a planet 438 00:38:37,745 --> 00:38:44,635 But scientists believe that crime This happens all over the universe 439 00:38:46,428 --> 00:38:49,135 If white dwarfs could destroy planets 440 00:38:49,135 --> 00:38:53,347 This means that ninety percent of Stars are capable of destroying planets 441 00:38:53,347 --> 00:38:57,508 There is no safe haven for planets 442 00:38:57,708 --> 00:39:00,600 It's also a bleak outlook for the future 443 00:39:00,800 --> 00:39:06,928 Our sun will start at a few billion General in transition to a white dwarf 444 00:39:07,128 --> 00:39:14,259 Inflicts initially to swallow both planets Inner rocks of Mercury and Venus 445 00:39:14,407 --> 00:39:18,203 This means that the planets rotate inside the sun 446 00:39:18,403 --> 00:39:23,469 Generally, we cross the void of space Something changes the way we move around the star 447 00:39:23,669 --> 00:39:27,734 But within the sun's gas Many intensify this orbit 448 00:39:27,734 --> 00:39:29,969 This will shift the energy of the planets 449 00:39:30,169 --> 00:39:32,964 They will turn more and more to the star 450 00:39:36,533 --> 00:39:40,501 Our inflated star explodes its entire outer layers 451 00:39:40,501 --> 00:39:44,376 To leave a dense white ring 452 00:39:44,576 --> 00:39:52,576 He reveals the burning earth in Death's orbit shrinks towards the sun 453 00:39:52,776 --> 00:39:55,618 If you get closer than the white star, you are lost 454 00:39:55,818 --> 00:39:58,999 Because your rocky planet will be torn apart in the end 455 00:39:59,237 --> 00:40:04,840 The intense gravity of our white ring tightens Over the burned remains of the inner planets 456 00:40:05,040 --> 00:40:08,542 One piece is torn 457 00:40:08,742 --> 00:40:13,619 If the planet survived inside the sun 458 00:40:13,619 --> 00:40:17,236 It is now near the surface of this white dwarf 459 00:40:17,436 --> 00:40:20,347 Mercury will disappear first, tear 460 00:40:20,547 --> 00:40:22,834 The flower will tear 461 00:40:23,034 --> 00:40:27,237 In the end, the Earth will be eliminated 462 00:40:27,437 --> 00:40:32,183 ,Maybe in a few billion years A space civilization will look at the sun 463 00:40:32,383 --> 00:40:37,476 The sun is no longer the shining star Huge, she is now a dead white dwarf 464 00:40:37,476 --> 00:40:41,530 They will observe the same planet The size of the earth revolves around it 465 00:40:41,730 --> 00:40:47,601 But the planet is similar to the case with Kepler data will end with your eyes 466 00:40:47,801 --> 00:40:53,395 They will ask if they have been in the past Civilization or life on this planet, the size of Earth 467 00:40:54,263 --> 00:41:00,683 The star that gives us light today And heat, our planet will be torn apart one day 468 00:41:02,756 --> 00:41:06,330 Our sun will become a deadly star 469 00:41:07,581 --> 00:41:14,525 But the atoms that are the planet Everything around us will return to the universe 470 00:41:14,525 --> 00:41:19,158 When our dead star gradually fades 471 00:41:19,358 --> 00:41:23,551 New stars can be formed by these relics 472 00:41:23,751 --> 00:41:28,793 The cycle of life and death can be restored in the universe 473 00:41:29,531 --> 00:41:33,440 It's sad to think of a star that kills planets 474 00:41:33,640 --> 00:41:37,817 Because the stars are breathing life Our sun gives us life 475 00:41:38,017 --> 00:41:39,432 We are because of them 476 00:41:39,632 --> 00:41:41,758 But it will also kill us in the end 477 00:41:41,958 --> 00:41:44,963 We revive the stars and our deadlines 478 00:41:45,163 --> 00:41:48,934 The stars may seem evil, but not life without death 479 00:41:48,934 --> 00:41:50,773 The cycle of the universe must turn 480 00:41:50,973 --> 00:41:53,658 It's the right path to the universe
