Black holes . ... Black holes are objects for which the gravitational attraction is so strong that nothing, not even light, can escape from it. ... The material inside a black hole is concentrated into a singularity: a single point of infinitely high density where space and time are infinitely distorted. ... The existence of such black holes has been inferred in cases where the black hole pulls gas of a companion star that orbits around it. ... Gravity's Fatal Atraction: Black Holes in The Universe. ...
