The Black Hole. - Samurai

This quote was added by samurai
A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing - not even particles and electromagnetic radiation such as light - can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon. Although crossing the event horizon has enormous effect on the fate of the object crossing it.
