The Concept of Black Hole


Black holes are celestial bodies exhibiting strong gravitational waves such that it has a tendency to pull every matter towards itself including electromagnetic radiations. The theory of General Relativity proposed by Albert Einstein explains that a compact mass can deform spacetime to form a black hole.
Black holes are extremely dense objects where its size is very less with respect to its mass. Due to high gravitation waves around it, not even light can escape. As scientists and astronauts aren’t able to go within a black hole, researchers are on experiments with various gases to observe the reactions that take place at the exterior region of a black hole. The boundary of the Blackhole from where no escape is possible is known as the Event Horizon.
Black holes are formed due to the explosion of massive stars. Stars produce energy through nuclear fusion where 2 lighter elements combine to form a heavy element. In this process, if Iron is formed, it starts consuming energy rather than producing. Therefore, outward pressure from the outer space exerts a force on the star making it implode. When the star reaches its peak level of compactness, it explodes resulting in the scattering of its particles across space, leaving behind certain mass structures. These structures, based on its size, turn out to be different celestial bodies. For instance, an average mass star becomes a white dwarf, a large mass star becomes a Neutron star while a very large mass star turns out to be a Black Hole.
Black holes are black in color, thus making it difficult to view it so easily. However, as planets revolve around the sun, similarly, celestial bodies revolve around a black hole due to its strong gravitation force, which in turn helps us to detect or identify the position of a black hole.
Schwarzschild Radius (Rs) is used to determine the radius of the Event Horizon. It was proposed by Karl Schwarzschild using Einstein’s General Theory of Relativity. It is also used to determine the density of a black hole.
However, we can also create black holes in Earth with the help of a device named Particle Accelerator where protons & electrons are made to collide against each other, resulting in the release of huge amount of energy in a very compact region, thus making it denser and hence creating a micro black hole, which gradually evaporates. The most interesting fact about a black hole is, Time slows down near the Event Horizon due to the presence of high gravitation waves.
Most scientists worldwide are concerned about Black Holes and are conducting numerous researches on it. It has turned out to be the foretest topic of study of Theoretical Physics.

    The root of your writing while appearing reasonable in the beginning, did not settle perfectly with me after some time. Somewhere throughout the sentences you actually managed to make me a believer but just for a very short while. I however have got a problem with your jumps in logic and you would do nicely to help fill in those gaps. When you actually can accomplish that, I would certainly be amazed.
