黑洞作为宇宙中最神秘莫测的天体，它的体积无限小，密度无限大。周围存在着一个界面，任何物体只要越过这个界面就休想再逃出来，就连宇宙中速度最快的光也不例外
我们知道，黑洞诞生于垂死的超大质量恒星，当一颗质量是太阳100倍以上的超巨星死亡时，它内核的燃料已经枯竭，无法维持燃烧。内核就会在引力的挤压下塌陷形成一个黑洞。
黑洞是宇宙中最神秘莫测的天体，也是质量最大的天体。黑洞的体积非常小，但它的引力是无限大的，大到连光都无法逃脱。黑洞是个无比贪婪的家伙。它所经过地方的物质都会被它吞噬。
如果一个黑洞慢慢靠近地球，地球上会发生什么情况呢？
当黑洞慢慢靠近地球时，地球上会发生很多异常现象。首先它会吸走大气层，它会让大气层像龙卷风那样旋转着进入黑洞。当黑洞靠的越近，对地球的影响就越强烈，你坐在那里就能感觉到一股力量把你拉离地球，然后咻的一声消失不见。用不了多久，黑洞的引力就会把地球撕得粉碎。这股力量将地球彻底瓦解，所有物质撕成碎片，最终所有物质都被它吞噬。
原子弹去轰管用吗？
曾几何时，一颗不成熟的小小原子弹便能把一座城市夷为平地，而如今全世界竟拥有15395枚超级核弹头！其中美国1983年就服役的B83型热核弹头是当年那颗原子弹威力的75倍！那么对准黑洞并同时释放这一万枚核弹头能否炸死这“宇宙幽灵”呢？
2014年，人类第一次观察到名为PGC43234的黑洞吞噬一颗恒星的画面。这颗黑洞质量为太阳的100万倍，其实这个质量并不算大，银河系的中央黑洞质量为400万倍太阳质量。在超大质量黑洞家族中这只是一个“乳臭未干的幼童”而已。
我们的太阳内核每秒钟爆发的能量约为4.0*1026J，相当于10亿颗广岛原子弹爆发的威力。而普通黑洞能在一秒钟之内轻轻松松吞噬并消化整个如太阳般大小的恒星，连饱嗝都不会打一声。所以，结果就是全球所有核弹头同时瞄准投向黑洞所造成的影响就像往太阳上扔了一粒炮仗一样，简直滑稽可笑。
如果有一天地球不幸被黑洞吞噬了，我们会怎样呢？我们还会活着吗？或者直接消失在暗无天日的黑洞中，失去任何知觉呢？有学者提出，进入黑洞的物质都会受到其拉力影响，被它拉伸。而地球也不例外，如果地球落入黑洞中，地球会被黑洞二维化，拉伸成为无限长的两端。
如果人类的科技在黑洞到来之前已经非常发达，能够进行星际旅行的话，在黑洞没有吞噬地球之前，人类可以乘坐太空飞船逃离地球。假如以目前的科技来看。一个黑洞接近地球，人类的唯一命运就是和地球一起灭亡。
英语翻译：As the most mysterious celestial body in the universe, black holes are infinitely small in size and infinitely dense. There is an interface around, any object can never escape as long as it crosses this interface, even the fastest light in the universe
We know that a black hole was born from a dying supermassive star. When a supergiant star with a mass more than 100 times the sun dies, the fuel in its core has been exhausted and cannot sustain combustion. The inner core will collapse under the squeeze of gravity to form a black hole.
Black holes are the most mysterious and unpredictable celestial bodies in the universe, and they are also the most massive celestial bodies. The size of a black hole is very small, but its gravity is infinite, so large that even light cannot escape. The black hole is a very greedy guy. The material in the place it passes will be swallowed by it.
If a black hole slowly approaches the earth, what will happen on the earth?
When the black hole slowly approaches the earth, many abnormal phenomena will occur on the earth. First, it will suck the atmosphere away, and it will cause the atmosphere to spin into the black hole like a tornado. The closer the black hole is, the stronger the impact on the earth. Sitting there, you can feel a force pulling you away from the earth, and then disappear with a scream. Before long, the gravity of the black hole will tear the earth to pieces. This force completely disintegrated the earth, tearing all matter into pieces, and eventually all matter was swallowed by it.
Does the atomic bomb work?
Once upon a time, an immature little atomic bomb could razor a city to the ground, but now the world has 15,395 super nuclear warheads! Among them, the B83 thermonuclear warhead in service in the United States in 1983 is 75 times the power of the atomic bomb that year! Can aiming at the black hole and releasing these ten thousand nuclear warheads at the same time blow up this "cosmic ghost"?
In 2014, mankind first observed a black hole named PGC43234 swallowing a star. The mass of this black hole is 1 million times that of the sun. In fact, this mass is not large. The central black hole in the Milky Way has a mass of 4 million times the mass of the sun. In the supermassive black hole family, this is just a "baby child".
The energy of our sun’s inner core is about 4.0*1026J per second, which is equivalent to the power of 1 billion Hiroshima atomic bombs. An ordinary black hole can easily swallow and digest an entire star the size of the sun in one second, without even burping. Therefore, the result is that the impact of all nuclear warheads in the world aiming at the black hole at the same time is like throwing a firecracker on the sun, which is simply ridiculous.
What will happen to us if the earth is unfortunately swallowed by a black hole one day? Will we still live? Or just disappear into the dark black hole and lose any consciousness? Some scholars have suggested that all matter entering a black hole will be affected by its pulling force and stretched by it. The earth is no exception. If the earth falls into a black hole, the earth will be two-dimensional by the black hole and stretched into infinite ends.
If human technology was already very advanced before the arrival of the black hole, and could carry out interstellar travel, humans could escape from the earth in a spaceship before the black hole swallowed the earth. If you look at the current technology. When a black hole approaches the earth, the only destiny of mankind is to perish with the earth.
