What is the opposite of a black hole?

White holes
White holes, which are theoretically the exact opposites of black holes, could constitute a major portion of the mysterious dark matter that’s thought to make up most of the matter in the universe, a new study finds. And some of these bizarre white holes may even predate the Big Bang, the researchers said.

Are white holes and black holes the same?

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. General Relativity is time symmetric.

Is a white hole an old black hole?

A white hole is a bizarre cosmic object which is intensely bright, and from which matter gushes rather than disappears. In other words, it’s the exact opposite of a black hole. But unlike black holes, there’s no consensus about whether white holes exist, or how they’d be formed.

What is the difference between a black and white hole?

A white hole is hypothetical region in spacetime , into which nothing can be entered , but from it light and matter comes. but in black hole , nothing comes out except radiations , in it everything goes and no one( even the light) cant escape.

What is on the other side of a white hole?

Instead, the collapsing matter on the other side of the event horizon reaches an enormous but finite density and rebounds, forming a regular Einstein–Rosen bridge. The other side of the bridge becomes a new, growing baby universe. For observers in the baby universe, the parent universe appears as the only white hole.

What is inside the white hole?

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.

What is a white hole and is it real?

A white hole is a bizarre cosmic object which is intensely bright, and from which matter gushes rather than disappears. In other words, it’s the exact opposite of a black hole. But unlike black holes, there’s no consensus about whether white holes exist, or how they’d be formed.

What is the reverse of a black hole?

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 escape. White holes appear in the theory of eternal black holes.

Is the observable universe the inside of a black hole?

Accordingly, the observable universe is the Einstein–Rosen interior of a black hole existing as one of possibly many inside a larger universe. The Big Bang was a nonsingular Big Bounce at which the observable universe had a finite, minimum scale factor.

Do black holes come from a big bang?

A view of black holes first proposed in the late 1980s might be interpreted as shedding some light on the nature of classical white holes. Some researchers have proposed that when a black hole forms, a Big Bang may occur at the core, which would create a new universe that expands outside of the parent universe.
