White hole
In astrophysics, a white hole is a postulated celestial body that spews out matter, in essence an anti-black hole, or the time reversal of a black hole. White holes have not been proved or seen and must have a sister black hole. White holes may violate the second law of thermodynamics.
Schwarzschild wormholes are extremely unstable.
Some speculation exists that quasars are actually white holes instead of supermassive black holes.
White holes may be formed when an antimatter star collapses. White holes, unlike black holes, allow things to come out but not go in.
