The Universe reserves us an infinity of enigmas, many of them man will never unravel, so what else exists in this medium are theories. Most people have heard of the black hole, however, the white hole is little known. White hole is a kind of regression (in time) of a black hole. In general, a number of materials suddenly emerge from a white hole; a more obvious example of a white hole is the Big Bang, in its most primitive process. It can be thought of as space contained beyond the confines of a black hole.
Theoretically, a white hole consists of a kind of “tunnel” that connects two opposite sides of outer space, if something enters one end of the “channel” it will immediately reach the other part.
The information presented is in accordance with the theory of relativity. According to this theory, the black hole is a region of outer space from which matter cannot escape. The white hole, on the other hand, is a region of outer space where nothing can fall - due to the enormous gravitational force, which does not allow such displacement.
