What is a black hole?
Millions of stars are born and die every day. These stars have very large, medium and small stars. Each star dies according to its size. When the stars die, there is a huge explosion. This explosion is called “supernova”. The blast emitted a great deal of light. If the collapsing star is of the largest size, it disappears completely. Even a medium-sized neutron takes the form of a star and begins to spin very fast, and if a shattered star is small in size, it will shrink into a black hole after it becomes a supernova.
A star loses its light when the hydrogen and helium gases in it stop colliding with each other, this is the stage of their extinction. In a small star like the Sun this phase will come after millions of years but in the case of large stars this phase comes in a few million years. At this stage, when the star is destroyed, its outer surface is scattered far and wide and the center of gravity of the destroyed star is so strong that it pulls everything inside itself. This center is called the black hole. ۔ Light can’t even get out of a black hole. Scientists say that there are many black holes inside each galaxy.
