White Holes

Albert Einstein proved through mathematics, the existence of black holes, which were later observed and confirmed to physically exist. Einstein also proved through his equations that white holes existed. White Hole is a hypothetical region of space-time that cannot be entered from the outside, although matter and light can escape from it. In this sense, it is the reverse of a black hole. Some believe Big Bang might have been produced by a supermassive white hole explosion. It is still a mystery if white holes can exist as none have been observed so far.
