'nothing, not even light'

[Divinus Arma]

The gravitational field is so strong that the escape velocity near it exceeds the speed of light. This implies that nothing, not even light, can escape its gravity, hence the word "black."

Formed in one of three main processes, they exert so much gravitational force that nothing - not even light - can escape their pull.

Black holes are places in space where the force of gravity is so strong that nothing, not even light, can escape

By a score of 135 to zero, scientists using NASA's Rossi X-ray Timing Explorer have compared suspected neutron stars and black holes and found that the black holes behaved as if each one has an event horizon, the theoretical border from beyond which nothing, not even light, can escape.

If a star, for example, collapses beyond some critical radius, Rc, the gravitational forces at the surface will be so great that the escape velocity of any object will be greater than the speed of light. According to Einstein, then, once this critical radius is reached, nothing, not even light will be able to escape from the surface of the star.

A black hole's immense gravity accelerates nearby matter and energy, which spirals inward and eventually reaches the speed of light. At that speed, the incoming stuff crosses a so-called "event horizon," a sphere beyond which events cannot be seen because nothing, not even light, comes back out.

A team of astronomers from MIT and Harvard have observed that a certain kind of explosion seen on neutron stars is never seen coming from black holes. This is strong evidence for the existence of a black hole's event horizon; the point at which nothing, not even light, can escape from its grasp.

Black holes are celestial objects with gravity so intense that nothing, not even light, can escape from them once past their boundary, called the event horizon.

One way to make a black hole, theorists agree, is to explode a very massive star. In one of these supernova events, outer portions of the star are flung into space. Some material falls back, however, and collapses into a sphere so dense that nothing, not even light, can escape.

It had to be done. The list of google returns creates an event horizon and goes on for eternity until nothing, not even light, can escape.
