All you need to know about Black holes

 The black hole is one of the discoveries made that has changed everyone’s perspective about outer space and the Universe.  

What is Black Hole?

When we here the term black hole, we usually think of a massive hole that engulfs anything that comes in its way, but scientists have something other to discuss explain which is a bit more different and diverse point of view. In technical terms, the black hole is a region of spacetime exhibiting strong gravitational force that nothing can get out of it, not even a ray of light. The general relativity theory foretells that adequately compact mass can deform spacetime to create a black hole. 

In simpler terms, a black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is strong because the matter has squeezed into a tiny space.

Size

Regarding the size of black holes, they can be as small as one atom or can be massive as 1 million suns put together. After studying some more about these mysterious black holes, scientists, and researchers have found proof that every large galaxy has an enormous black hole at its center. So our Universe is home to many different sizes of a black hole that can be found almost anywhere in space.

History of Black Holes

Black holes have been a part of our Universe for a long time, but the first theoretical explanation of black holes was given in 1916 by a scientist named Karl Schwarzschild. He was the first scientist to have explained a modern solution of general relativity that would characterize a black hole. Different scientists tried to learn more about black holes, and the first-ever physical black hole was spotted in 1971. Then in 2019, the Event Horizon Telescope collaboration revealed the first image of a black hole. 

Scientific theories

For the past couple of years, different scientists have tried to study the Universe, and its working, and everyone has come forward with their theory. Galileo, Stephen Hawking, Einstein are a few of the many scientists that have studied outer space and have tried to find answers of our origin in the infinity we inhabit. 

Physical proof

So now that we have physical proof of black holes, what would it mean for us? Well, our demise won’t be like, as many assume. Black holes may be supermassive, but our planet well never falls into one. Not any black hole is close enough, and the sun, will never turn into one. Even if it does, having the same mass as of the sun, all the planets instead of falling into the black hole would orbit around. Scientists still do not know what is inside a black hole, no one can travel into one, and because it has a massive amount of gravity, no one will be able to return.

Black Holes dangerous or safe

Black Holes are so puzzling, massive, and still unspecified, but they are not dangerous. Nobody needs to worry about them. They are so far away from human beings; they can not cause any kind of harm to humans.  However, Stephen Hawking, who was a British theoretical cosmologist, died in a black hole as he was shining a light on them. His name will always be tied with the black holes. 

Concluding it, black holes are merely compact objects. Only stars that are huge become black holes after their life cycle. Not a single particle can escape through it as they have a high gravitational pull. They are huge and are not dangerous at all. Researches are in the process of their precise nature.
