Detailed explanation-1: -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.
Detailed explanation-2: -A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. The strong gravity occurs because matter has been pressed into a tiny space. This compression can take place at the end of a star’s life. Some black holes are a result of dying stars.
Detailed explanation-3: -UNIVERSITY PARK, Pa.-Light cannot escape from a black hole, but for the first time ever, researchers have observed light from behind a black hole-a scenario that was predicted by Einstein’s theory of General Relativity but never confirmed, until now.
