white hole
This term is used exclusively within the realm of theoretical physics and general relativity. It describes a hypothetical celestial object that serves as a temporal and spatial inversion of a black hole. While a black hole possesses an event horizon that prevents anything from escaping, a white hole possesses an event horizon that prevents anything from entering.
Because white holes are mathematical solutions to the Einstein field equations rather than observed astronomical phenomena, the term is typically used in speculative scientific discourse or science fiction. It is often paired with the concept of a wormhole, suggesting that a black hole and a white hole could be the two opposite ends of a single bridge through spacetime.
