white hole
Sign in to savehypothetical region of spacetime that serves as the opposite of a black hole
A white hole is a theoretical, opposite counterpart to a black hole — while a black hole pulls everything in and nothing escapes, a white hole would only push matter and light outward and nothing could enter it. Though they're predicted by the same equations that describe black holes, white holes have never been observed and remain purely hypothetical, making them an intriguing subject for theoretical physicists exploring the nature of spacetime.
