even light cannot escape its gravity
|
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. This can happen when a star is dying. Because no light can get out, people can’t see black holes.
Detailed explanation-2: -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.
Detailed explanation-3: -The reason nothing can escape a black hole is that, within the event horizon, space is curved to the point where all directions are actually pointing inside. The event horizon of a black hole is where gravity is such that not even light can escape.
Detailed explanation-4: -While black holes are mysterious and exotic, they are also a key consequence of how gravity works: When a lot of mass gets compressed into a small enough space, the resulting object rips the very fabric of space and time, becoming what is called a singularity.
