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.
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.
7 maj 2024 · In astrophysics, a white hole represents a theoretical phenomenon where matter and light would emerge from, rather than be pulled into, a certain area in space. It's the exact opposite of a black hole.
19 paź 2023 · White holes are theoretical cosmic phenomena that function in the opposite way as black holes; instead of attracting matter into an infinitely dense singularity due to immense gravity, it pushes out matter and light, preventing anything from re-entering past its event horizon.
27 gru 2010 · A white hole is like a black hole, except that the waterfall is “falling” up instead of down. White holes are exact mathematical solutions of general relativity — they are theoretical...
11 lip 2023 · White holes are theoretical cosmic regions that are opposite to black holes. Just as nothing can escape a black hole, nothing can enter a white hole.
28 maj 2024 · Often considered the reverse of black holes, white holes are hypothetical regions in spacetime that, unlike their counterparts, cannot be entered from the outside, but instead expel matter and energy.
