Stephen Hawking
Stephen W.Hawking is a British physicist, cosmologist, and author. He developed theorems about so called Hawking radiation emitted by black holes.
Hawking Radiations
Hawking radiation, first hypotized by S. Hawking, is a black body radiation that is predicted to be emitted by black holes, due to quantum effects near the event horizon.
Bridge to other dimensions
In 1963, the New Zealand mathematician Roy Kerr found that if a black hole is rotating a singularity still forms, but in the form of a ring, not a point.

Gravitational Collapse
Gravitational collapse occurs when an object's internal pressure is insufficient to resist its own gravity. It will become of the size of the earth but a hundred thousand times more dense.

The Ergosphere

Rotating black holes are surrounded by a region of spacetime in which it is impossible to stand still, called the ergosphere.

Quasars and Pulsars
Pulsars are among the strangest objects in the universe.A Quasar is a class of active galaxy amongst the most distant and luminous astromical objects.
