what is black hole. if any body go inside what happens
Answers
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.
Answer:
A black hole is a region of spacetime exhibiting gravitational acceleration so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
Not even light can escape, and light moves very very fast! The point where light can just escape is called the event horizon, and after you pass this point you are inside the black hole and can't get out. It is possible however to enter a black hole and not die!
