11 lip 2023 · The white hole is, in a hand-wavy sense, the inverse of a black hole. So in a black hole, you have an intense gravitational field that pulls things in you've got this one-way...

- What is The Black Hole Information Paradox
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.
7 maj 2024 · Andrew Hamilton, an astrophysicist, proposes that if white holes exist, they could be remnants of supermassive black holes that underwent a quantum gravitational transformation, reversing their roles from absorbing to expelling mass and energy. This theory is called loop quantum gravity.
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.
13 sie 2023 · White holes would be even stranger than black holes. They would still have singularities at their centers and event horizons at their borders. They would still be massive, gravitating...
6 lis 2023 · Very simply, a white hole could be considered a black hole that runs backward in time. White holes would have some things in common with black holes: they would possess the characteristics of...
15 wrz 2023 · White holes are time-reversed black holes. For a black hole, a particle may fall in with a trajectory that terminates at the singularity. The time-reversed version of that picture is that a particle "is created at the singularity with sufficient speed that it can escape" (roughly).
