How does a white hole work?

In general relativity, a white hole is a hypothetical region of spacetime and singularity that cannot be entered from the outside, although energy-matter, light and information can escape from it. White holes appear in the theory of eternal black holes.

Do white holes break the laws of physics?

The negative square root solution inside the horizon represents a white hole. A white hole is a black hole running backwards in time. Just as black holes swallow things irretrievably, so also do white holes spit them out. White holes cannot exist, since they violate the second law of thermodynamics.

Does a white hole have gravitational pull?

White holes don’t exist. As virtually just a hole in space, they would have no gravity. It depends on what you mean by gravity: If by having gravity we mean that other objects will be attracted to the white hole, than no, it doesn’t have gravity.

What happens if a white hole collides with a black hole?

The mass the white hole is expelling is also being turned into energy for the black hole. So if a white hole and black hole collided, we’d have a massive black hole roaming around the Universe, destroying everything in its path.

What happens if a black hole meets a white hole?

Is white hole connected to black hole?

Further, black holes and white holes are as intertwined as the names suggest. White holes may simply be the opposite end of black holes, connected by theoretical tunnels of space-time called (of course) wormholes.

What happens when a black hole collides with a white hole?

What does a white hole look like in theory?

In theory, a white hole looks similar to a black hole, but instead of sucking matter in, a white hole pushes matter away. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.

Is there a white hole in the future?

In addition to a black hole region in the future, such a solution of the Einstein field equations has a white hole region in its past. This region does not exist for black holes that have formed through gravitational collapse, however, nor are there any observed physical processes through which a white hole could be formed.

Can a white hole form from a supermassive black hole?

This region does not exist for black holes that have formed through gravitational collapse, however, nor are there any observed physical processes through which a white hole could be formed. Supermassive black holes (SBHs) are theoretically predicted to be at the center of every galaxy and that possibly, a galaxy cannot form without one.

Will White holes come to dominate the universe?

In this picture, white holes would one day come to dominate the universe, after the stars have burnt out and black holes have withered. Any observers then could easily detect the objects as relatively large particles Haggard speculates, but those days are countless trillions of times the current age of the universe in the future.
