Although we can’t see a black hole, the material around it is visible. Material falling into a black hole forms a disk, similar to a whirlpool in a bathtub drain.
WebTo escape from within a black hole requires faster than light speeds, but according to Einstein's theory of gravity, General Relativity, gravity is the distortion of space and time caused by the presence of mass. As such, gravity doesn't escape from within the interior of the black hole: it's simply caused by the hole's presence.
