A white hole is a hypothetical region of spacetime that cannot be entered from the outside, but can emit energy, matter and information. Learn about the origin, properties and possible scenarios of white holes in general relativity and cosmology.
3 lut 2023 · White holes are the time-reversed equivalents of black holes, where matter and energy emerge from a singularity. They are mathematically plausible, but not observed, and may be related to the origins of our Universe.
13 sie 2023 · White holes are theoretical cosmic regions that function in an opposite way to black holes, but they are not allowed by the laws of physics. Learn why general relativity is not enough to create white holes, and how thermodynamics and stability rule them out.
7 maj 2024 · A white hole is a theoretical phenomenon where matter and light would emerge from, rather than be pulled into, a certain area in space. Learn about the theoretical basis, quantum considerations and observational challenges of white holes, as well as their connections to other cosmic phenomena.
19 sie 2014 · White holes are hypothetical cosmic creatures that are the opposite of black holes. Learn how a speculative theory called loop quantum gravity suggests that white holes could form from spinning black holes and resolve the black hole information paradox.
11 lip 2023 · White holes are the time-reversed versions of black holes, where nothing can enter but everything can leave. Learn about their origin, properties, and why they may or may not exist in the real universe.
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.
