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 · Black holes have long held the spotlight as celestial objects from which nothing, not even light, can escape. However, theoretical physicists propose a less understood but equally fascinating counterpart: the white hole. Unlike black holes, which attract matter, white holes would repel it.
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.
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 and thermodynamics rule out the possibility of white holes in the real universe.
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...
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...
