Question

what is the black hole???​

Answer 1

Answer:

Black hole is a region in space with very strong gravitational field that not even light can escape from it.

Answer 2

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.
