The theoretical opposite of a black hole: the white hole
In short: While black holes are famous for trapping everything, white holes represent their mathematical mirror image. This video explores the physics and theoretical possibility of regions in space that expel matter rather than consuming it.
A white hole is a hypothetical celestial object that functions as the inverse of a black hole. While a black hole possesses an event horizon from which nothing can escape, a white hole would have an event horizon that prevents anything from entering.
The concept arises from the mathematical solutions to Einstein's field equations. Because these objects are theoretical, they have not been observed in the universe, but they remain a significant subject of study in general relativity and cosmology.
