In [[astrophysics]], a '''white hole''' is the opposite of a [[black hole]]. Where a black hole attracts and sucks in any nearby [[matter]], a white hole does the opposite and pushes nearby matter away. The black and white holes are connected by a [[wormhole]]But, According to the laws of Thermodynamics, The amount of entropy in the universe can only stay constant or increase. In case of a white hole, entropy tends to decrease so it can not be considered as a possibility with our present understanding of Energy. (see diagram).

A white hole is a thing that has been recently discovered in the field of astronomy. You will find it in mathematics if you investigate the space-time area surrounding the black hole taking away the actual star that formed the black hole. If you add any matter to the area, the white hole disappears.
