Lurking in the depths of the mathematics of Einstein's general relatively is an object even stranger than the mysterious black hole. In fact it's the black holes mirror twin, the white hole. A white hole is the opposite of a black hole in a very literal mathematical sense. In fact, it's a time reversed black hole. A white hole is a region of outward flowing space-time. Nothing outside a white hole can ever enter, and everything inside must be ejected. White holes are probably a figment of mathematical imagination, but they're a fascinating one, and the idea may help us understand the origin of the universe. It has been proposed that when a black hole forms a white hole forms on the opposite side. Energy entering the black hole exits the white hole. Some even suggest the resulting white hole is the Big Bang of a new universe and that, in fact, our universe formed that way. Physicsts describe a white hole as a black hole's "time reversal". While a black hole event horizon is a sphere of no return, a white hole event horizon is a boundary of no admission. If white holes are connected to black holes through wormholes, the white hole could potentially provide a means of exploring new parts of the universe and even other universes, as matter and energy could travel through the wormhole without crossing the space in between. A white hole is almost like anti-gravity endlessly ejecting material. White holes remain an intriguing possibilty, but their existence, at this point in time, can only be said to be speculative, at best. Some have theorized that at the end of a black hole's life, potentially quadrillions of years in the future, it could " bounce back" as a white hole.
