More about this video
A black hole is a celestial body or simply a place in space where the gravitational pull is so high that nothing, not even light can escape it. This is why it's completely black, and hence it's called a black hole. A black hole's “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light.
