Black Holes

Black hole is one thing which scares me the most, because well black colour depicts fear and also black hole is one thing which no one has ever discovered, but we do know about black holes.

Black holes are formed after a star has gone supernova. They either become neutron stars or become black holes. Then they become a region in space with immense gravity and even the fastest known object (Light) can’t escape it. The boundary of a black hole is called the event horizon, a point of no return, and beyond which we can’t see at all. When something crosses the event horizon it collapses in the black holes singularities, and then space, time, gravity or any other law of physics doesn't apply. 

So, now lets see how a black hole is formed. Stars are incredibly massive collections of mostly hydrogen atoms that collapse from enormous gas clouds under their own gravity. In their core nuclear fusion crushes hydrogen atoms into helium liberating a lot of energy and heat. Then that energy in the form of radiation pushes against the gravity maintaining a delicate balance between radiation and gravity, as long as there is fusion in the core the star will remain stable but in massive stars, way bigger than our sun, in there is more pressure than small stars therefore they allow it to fuse with many elements till iron or Fe. Unlike any other elements before iron (Silicon, oxygen, neon, helium, carbon and hydrogen) the fusion process doesn’t create any energy. Iron is on the center
of the star until it increases and creates an imbalance in the radiation and gravity scale. Due to this the core collapses and the star implodes. Now, the star is moving really fast and allowing all the mass around it to enter its core, and now it's at this very moment when most of the heavy and reactive elements are created and the star dies in the supernova explosion. This explosion will either create a neutron star or if the star is massive enough then the entire core’s mass is collapsed into a black hole.

Now, everybody thinks what will happen if we are trapped into the blackhole. Well, The time would move much faster and either you will have a quick death or a very quick death as the decreasing temperature and because our earth will collapse and break into pieces. The Earth would be moving at such high speed that we would not be able to experience light, and our body would tear apart because of the speed.
