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 …

2023年7月11日 · See how white holes emerge from the same space-time diagrams as black holes in PBS's space-time video.

2024年5月7日 · 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 …

2023年8月13日 · Black holes seem to get all the attention. But what about their mirror twins, white holes? Do they exist? And, if so, where are they?

They are predicted by Einstein’s theory of gravity, and are most often mentioned in the context of ‘wormholes’, in which a black hole acts as the entry point to a tunnel through space and time, …

2023年2月3日 · In Einstein’s general relativity, one of the very first possibilities that was ever discovered was for a black hole: a region of space with so much matter-and-energy in one …

2011年5月27日 · White holes are the theoretical opposite of black holes. As black holes draw in surrounding stars, dust, passing spaceships – whatever comes too near – so white holes, by …

2023年11月6日 · White holes are the opposite of black holes in almost every way. General relativity predicts their existence, but why haven’t astronomers found any yet?

2023年10月19日 · 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 …

2024年5月28日 · Explore the enigma of white holes, their theoretical basis in general relativity, challenges in research, and implications for quantum gravity. White holes, a theoretical …
