In general relativity, a white hole is a hypothetical region of spacetime and singularity that cannot be entered from the outside, although energy - matter, light and information can escape from it. In this sense, it is the reverse of a black hole, from which energy-matter, light and information cannot escape.

3 lut 2023 · In general relativity, white holes are just as mathematically plausible as black holes. Black holes are real; what about white holes? Although there are no observed white holes...
19 sie 2014 · Physicists have white holes: cosmic creatures that straddle the line between tall tale and reality. Yet to be seen in the wild, white holes may be only mathematical monsters. But new...
A white hole is a bizarre cosmic object which is intensely bright, and from which matter gushes rather than disappears. In other words, it’s the exact opposite of a black hole. But unlike black holes, there’s no consensus about whether white holes exist, or how they’d be formed.
A white hole is a time-reversed black hole – a region of spacetime where matter spontaneously appears and explodes outwards, rather than implodes and disappears as with a black hole. White holes are the opposite of black holes, in that they spit out light and matter, rather than trapping it.
