Why white holes might existįor a while, white holes seemed to share the fate of wormholes - mathematically permissible contortions of space-time likely prohibited by reality.

'A long-lived white hole, I think, is very unlikely,' said Hal Haggard, a theoretical physicist at Bard College in New York. Any outgoing matter would collide with the matter in orbit, and the system would collapse into a black hole. An event horizon exploding into a functional star would look a bit like an egg unscrambling itself - a violation of the statistical law demanding that the universe gets messier over time.Įven if large white holes did form, they probably wouldn't hang around too long. A black hole cordons off its bit of space when a star collapses into a tiny volume, but playing this video backwards doesn't make physical sense.

While general relativity describes white holes in theory, no one knows how one might actually form.
