White hole - Wikipedia
In the 1930s, physicists Robert Oppenheimer and Hartland Snyder introduced the idea of white holes as a solution to Einstein's equations of general relativity. These equations, the foundation of modern physics, describe the curvature of spacetime due to massive objects.
White holes: Facts about black holes' neglected twins | Space
2023年7月11日 · White holes emerge from the solutions of Einstein's theory of general relativity devised by Karl Schwarzschild in 1916, just a year after the theory was first published. Schwarzschild was the...
What Is a White Hole? Does the Cosmic Phenomenon Exist?
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 opposite of a black hole.
Could white holes actually exist? | Space
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?
The Mystery of White Holes: Could They Solve the Enigma of …
2024年3月14日 · Scientists are becoming increasingly convinced that white holes, the exact opposite of black holes, may actually exist. These hypothetical objects, predicted by Einstein’s general theory of relativity, can only eject matter and light, making it …
What are white holes, and do they really exist? - Big Think
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 place that from...
Webb Telescope Proves Existence of White Holes
2022年8月30日 · Using the James Webb Space Telescope, researchers have finally been able to observe a white hole in action. They were shocked to find out that it behaves very similarly to black holes; by sucking up matter and energy from its surroundings.

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?
When Black Holes Die, They Are Reborn As White Holes
2024年7月31日 · The new work suggests that when black holes die, they turn into white holes. That myriads of tiny white holes could be passing through the Earth at any time. And that these objects are an ideal candidate for the dark matter that cosmologists believe fills the universe but have never directly observed.
White holes in space: what are they? - Orbital Today
2022年12月19日 · Some astronomers believe that there is an antipode of black holes in space – white holes. Has a white hole ever been discovered, and does it exist at all?
