In 1967, John Wheeler coined the term ‘black hole’. Black holes are the residue that is left when hyper or giant stars die. Once the stars end their life cycle and burn out the entire fuel needed for sustaining its shape and operation, the stars implode into the center and pull out abundant mass into a single point in space. This creates a point where the gravitational force is too powerful to be combatted.
Black hole is formed when the large portion of the remaining old mass compacts together. Singularity is the core of the black hole where existence of everything ends at once. Even light gets trapped in the black hole owing to the strong force of gravity.
MORE ABOUT THE BLACK HOLES
The nearest Black Hole lies 27,000 light years away from our solar system. Max Planck Institute for Extraterrestrial Physics conducted a research where researchers used telescopes for observing the stars that circled in the center of the Milky Way. It proved the existence of a black hole.
Black holes are result of the exploding and collapsing of large stars in on themselves. Scientists have varied forms of belief that range from the concept of a White Hole to the concept of Black holes being empty. Black holes suck in everything that happens to be close by, but they remain empty.
Closer to the black hole, even light cannot move fast enough to escape the gravitational pull. Hence Singularity has darkness all around it. Even Horizon is the point at which the gravitational pull of the black hole becomes strong enough to prevent light from escaping.
WHITE HOLES AND WORMHOLES
Some scientists believe that a White Hole lies at the bottom of the Black hole, which opens up the doors to another reality. White Hole is similar to Black Hole in the respect that things cannot go in but can go out. This, in turn, forms the basis of another concept called ‘Wormhole’ which assumes that a single tunnel connects all the different sections of space and time. Matter can travel through the wormholes.
There are various theories circulating that speculate about the bottom of black hole, but nothing can be proven. This happens because the black hole is too far away to be reached. And whatever comes close to it, it sucks it in forever.
