About what asteroid is Wandering Black Hole 2012

Rest assured, 2012 is not the end of the world. Our Earth is in a perfect orbit, and even if an asteroid comes, we have Jupiter to keep us out. Jupiter is a gas giant with a gravitational pull that protects our Earth.

And black holes do exist, so don't worry, because our solar system doesn't have that big stars, and if they do, they're far away.

You are looking at the sky, the sky is also looking at you, human beings are dizzy by the magnifying glass, human beings are very powerful, the planet thinks that human beings are like bacteria, human beings look at the sky and look at the universe, human beings will not think about it, the continental plate carries so many people, and one day it will capsize, so you put these aside for the time being, after reading the third year of high school, don't read it anymore, after reading the third year of high school, get your survival instinct back, and by the way, send a famous saying "An inch of time is an inch of gold, and an inch of gold is difficult to buy an inch of time".

Have you heard the story of unfounded worries?

After all, the lifespan of human beings is shorter than that of cosmic bodies.

Remember: fear is the beginning of your acceptance of Him.

Poland ** is missing, Jobs resigns, Gaddafi is missing, Naoto Kan is stepping down, and only tells us one thing: it's time to start boarding....

Afraid of what? Jupiter, the guardian planet of our Earth, can block asteroids, there are indeed black holes in the Milky Way, but the possibility of coming to Earth is still very small, and there is nothing to prove that 2012 is the end of the world, so let's live the present days!!

The creation of black holes is similar to that of neutron stars; When a star is preparing to perish, its core rapidly shrinks and collapses under the influence of its own gravity, and becomes powerful**. When all the matter in the core turns into neutrons, the contraction process immediately stops, and it is compressed into a dense star, which also compresses the space and time inside. But in the case of black holes, because the mass of the star's core is so large that the contraction process goes on endlessly, the neutrons themselves are crushed into powder by the attraction of the squeezing gravity itself, leaving behind a matter of unimaginably high density.

The force generated due to the high quality is such that any object that comes close to it will be sucked into it. The black hole begins to devour the outer shell of the star, but the black hole cannot swallow so much matter, the black hole releases a portion of the matter, shooting out two pure rays of pure energy - gamma rays. It can also be understood simply:

Usually, the star originally contains only hydrogen, and the hydrogen atoms inside the star collide with each other and fuse. Due to the massive mass of stars, the energy produced by fusion competes with the gravitational pull of the stars to maintain the stability of the star structure. As a result of fusion, the internal structure of the hydrogen atom eventually changes, breaking down and forming a new element, helium, which then also participates in fusion, changing the structure to form lithium.

By analogy, according to the order of the periodic table, beryllium, boron, carbon, nitrogen, etc., will be formed in turn, until iron is formed, and the star will collapse. This is due to the fact that iron is quite stable and does not release energy when participating in fusion, while iron exists inside the star, causing the star to not have enough energy inside the star to compete with the gravitational pull of the massive star, which causes the star to collapse and eventually form a black hole. To say that it is "black" means that it is like a bottomless pit in the universe, once any matter falls into it, it can no longer escape.

Like white dwarfs and neutron stars, black holes may have evolved from stars that are several times more massive than the Sun. When a star ages, its thermonuclear reaction has depleted the fuel (hydrogen) in the center, and the gravitational power of the black hole. The energy generated by the center is running out.

In this way, it no longer has enough strength to carry the enormous weight of the shell. So under the weight of the shell, the core begins to collapse, and matter will march inexorably towards the central point, until finally a star with a near-infinitesimal volume and almost infinite density will be formed. And when its radius shrinks to a certain point (it must be smaller than the Schwarzschild radius), the mass-induced distortion of space-time makes it impossible for even light to shoot outward – and the "black hole" is born.
