Question

what is the evidence for black hole ? is it a theory or real ?i cant understand that say one.

Answer 1

Hey there!!

I guess you are a spacer lover too like me, coz the question sounds as if you are one. Well, talking about black holes are a theory, which had been predicted in 1916 by Albert Einstein with his general theory of relativity. Black Hole is really an amazing entity of this universe. And for the definition : A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes. They are invisible. Moreover, a black hole is a space from which light cant get out and a place which has the maximum gravity..so eventually anything going into the black hole will get squeezed enormously coz the gravity wud be constantly applying pressure on the body passing through the black hole. Its actually impossible for any human being to successfully pass through a black hole, unless and until a proper scientific equipment is developed. Yes, its true that scientists at NASA, ISRO and other space research centres are working hard to find the evidences relating to Black Holes. They still remain a mystery yet to be unraveled. The movie 'interstellar' a box office hit, explains clearly the theory of black holes. And as a part of the evidences found until now, scientists are saying that other solar systems like us , might exist in the black holes found yet. Other galaxies, like ours, the milky way galaxy, may also exist.

hope you found my answer helpful :D..thanx:)

Answer 2

Astronomers have found convincing evidence for a super massive black hole in the center of our own milky way galaxy,the galaxy NGC4258,the giant elliptical galaxy M87, and several others. Scientists verified the existence of the black holes by studying the speed of the clouds of gas orbiting those regions.In 1994,Hubble Space Telescope data measured the mass of an unseen object at the center of M87.
