Inscrutability Of Black Holes

Hey guys, this is Umar with my new blog post about ‘Black Holes’. There are some mysteries in this world to think upon. Some are resolved and some are under observations and some are still irresolvable and those who are irresolvable is due to because I believe human mind is in a bound state or what I consider is our brain can only think in a limited state of affairs. We can’t imagine beyond this blue sky because we don’t have the capability to do so. “Black Holes” are also one of those mysteries. So actually, what science says about it, it is a place where gravity is much powerful even light cannot escape through it. It crumbles the matter into small little pieces. Such things happen when a star dies after Supernova stipulation. Black holes are invisible. We cannot see them because they sop up the light as well. Scientists use some special sort of space telescopes to figure out where the black holes are and how they act in a different way from other things in space. Scientists imagine that these black holes are found nearly in any size even as petite as an atom or as huge as gigantic Sun.

Another category of black hole is called ‘Stellar’. Its mass can be up to 20 times more than our Sun. Those black holes which are found largest by our scientists are called ‘Super Massive Black holes’. These super massive black holes have masses that are more than 1 million Suns pooled together. Scientist believes that there is a super massive black hole in centre of every galaxy including our ‘Milky way’. The super massive black hole at the centre of ‘Milky Way’ galaxy is called ‘Sagittarius A’. It has a mass equal to about 4 million suns and would fit inside a very large ball that could hold a few million earths.

NASA is using satellites and telescopes that are traveling in space to learn more about black holes. These spacecraft help scientists answer questions about the universe. All common sense of physics like Newton's laws are simply thrown out of the window because Black holes completely distort time and space. As scientists get closer and closer to understanding the physics behind the Black hole, many equations are starting to not make sense anymore because the physics of Black holes are simply impossible to calculate perfectly. Some scientists believe it’s possible that black holes are ‘Worm Holes’ in Space: doorways to other points in the universe, or even other universes. But if you think about it, even if you made it in alive, it’s not clear how you’d escape the door on the other side, since this would be a Black Hole too.
