-- black holes, wormholes and white holes what is a black hole according to the general theory of relativity, a black hole is a region of space from which nothing, including light, can escape. A white hole is pretty much like an 'anti-black hole' a black hole is a place where matter can be lost from the universe a white hole is a place where (if it could exist with any matter in it - which it can't) matter would pop out into the universe.
(however, it is theoretically possible for a traveler to enter a rotating black hole, avoid the singularity, and travel into a rotating white hole which allows the traveler to escape into another universe) white holes appear in the theory of eternal black holes. Like black holes, white holes have properties like mass, charge, and angular momentum they attract matter like any other mass, but objects falling towards a white hole would never actually reach the white hole's event horizon.
In general relativity, a white hole is a hypothetical region of spacetime which cannot be entered from the outside, although matter and light can escape from it in this sense, it is the reverse of a black hole, which can only be entered from the outside and from which matter and light cannot escapewhite holes appear in the theory of eternal black holes. White holes would be the stark opposites of black holes, with an unfathomable amount of matter and information pouring out of them – but this must come from somewhere. People like to think of black holes and white holes as gateways through the universe it would be rather convenient if we could enter a black hole, zip acr.
Forget black holes, white holes are weirder and 'spewing matter from another universe' while scientists are still struggling to explain exactly what a black hole is, they are now examining the.
Introduction black holes are difficult enough to understand, but it gets much worse: also known as an “impossible possibility”, a white hole is a hypothetical, celestial body that emits energy—in the manner of a time-reversed black hole in simpler language, a white hole is the opposite of a black hole while a black hole sucks in all matter that crosses its event horizon, a white hole.
