Karl Schwarzchild
Black hole theory was first explained by Karl Schwarzchild in 1916 using Einstein's quantum theory of relativity. The possibility of white holes and wormholes developed as mathematical theories that sprang out of the model offered by Schwarzchild.
Black Holes
A black hole is a collapsed star that has reached the end of its life and has no nuclear fuel left to burn. The gravitational pull of a black hole is so great that matter from the universe is dragged into the black hole and light that passes into the path of a black hole cannot be seen on the other side.
White Holes
The white hole can be described in basic terms as an anti-black hole. The theory suggests that where the black hole drags matter and antimatter into itself, the white hole ejects matter and antimatter into the universe. Some theories claim that white holes spewing matter explains the ever-expanding nature of our universe.
Wormholes
White hole theory supports other unproved theories about the universe. One of these is the theory of the wormhole, or Einstein-Rosen Bridge. The wormhole is said to be a bridge connecting a black hole to a white hole. It is thought that when a black hole absorbs space matter, the matter must be ejected back into space in another destination in the universe or in another as yet undiscovered dimension. The wormhole is said to be the connection or tunnel between the black and white holes carrying the space matter to its new destination.
Mathematical Theory
White hole theory was developed soon after Schwarzchild's black hole model was unveiled, and it has remained controversial with mathematicians and scientists ever since. In 1962, John Wheeler presented a wormhole theory and with it offered mathematical evidence of white holes. Other theories put forward by experts such as quantum physicist Stephen Hawking claim that white holes are simply black holes when different theories are applied.
Physical Evidence
Evidence of black holes has been provided with the use of radio waves sent into space; images of a black hole have been captured using powerful telescopes. White holes and wormholes remain simply mathematical theories. Wormhole theory is being investigated in a more serious manner than white hole theory, which is not believed by the majority of the scientific fraternity.
