He used Newton's law of gravity to calculate that if a object were to be compressed into a very small radius, then the escape velocity of that object would be greater to the speed of light. ... The gravity is so big, that not even light itself can escape! ... Nothing, not even light can get out. ...
Otherwise the fact that nothing can travel faster that light means that the round trip to the nearest star would take at least eight years. ... This exploding star throws off its outer layers, and the remaining core continues to collapse inward at a rate equaling the speed of light - which means that no light can escape from it and becomes invisible. ... Any light rays emitted by the star are wrapped around the star. Because no light can escape, it is called a black hole(Davis 209). ... He found that the uncertainty principle, which says that particles cannot have both...
Moreover, the intense gravitational field of the black hole prevents any light or other electromagnetic radiation from escaping. ... The Cauchy horizon is a light-like surface which is the boundary of the domain of validity of the Cauchy problem. ... The most defining quality of a black hole is its emission of gravitational waves so strong they can cause light to bend toward it. ... Propagating at (or near) the speed of light, gravitational waves do not through space-time as such -- the fabric of space-time itself is oscillating. ... When the star is passed on into the event horizon t...
Also according to the theory of relativity, nothing can travel faster than the speed of light but most compact objects imaginable are predicted by General Relativity to have such strong gravitational force that nothing can escape them- not even light. For this reason, it is called a black hole; light, as a result disappears from the visible universe. John Mitchell, an English geologist, had written a paper in 1783 about the extraordinary strength of gravity- so strong that light could not escape it. ...
