Probably not. White holes appear as a possible "solution" of General Relativity, but there is no real reason to believe they exist. (Just as there is no way to DESTROY a black hole, there is no way to CREATE a white hole!)

A white hole is a theoretical concept that exists as a solution of certain equations. No white holes have ever been observed, and there are some fairly sound reasons for thinking that they probably cannot physically exist.

The term "white hole" has also been used for black holes which are so small that they lose mass through Hawking radiation faster than they gain it through accretion, but this is something slightly different (and, again, these are purely theoretical; none have ever been observed).

If there are black holes does that also mean that there are white holes scientifically?

No, it does not mean that.Black holes and white holes are two different "solutions" of the equations of General Relativity; but that doesn't imply that one, or the other, actually exist. It is now almost certain that black holes exist; as for white holes, there are theoretical problems that may make them impossible, such as: * A white hole is, in many aspects, there reverse of a black hole. And just as there is no way to destroy a black hole, there is no way to CREATE a white hole. * It seems that in a white hole, entropy would decrease over time.


What happens to the matter that gets spit out of the white hole inside of the white hole?

The existence, or possibility, of white holes has not been confirmed. Any ideas about white holes are very speculative.


Were there any sightings of white holes or black holes in the last 100 years?

Black holes have been detected (or at least evidence of their activity) White holes have never been observed, and remain theoretical for the time being.


What are white holes?

Hypothetical celestial bodies that behave in an opposite manner to black holes and rather than pulling everything in they spit matter out. White holes also have a unstable gravity and collapse and turn into black holes.


Is there a such thing as white holes and if there is what happens if a black hole collides with it?

It is not known whether there actually are white holes, or whether they might exist - and if they do, exactly what properties they would have. White holes are a possible solution to the equations of Relativity, but that doesn't mean they actually exist. The problem is that they are in a way the reverse of a black hole - nothing can get OUT OF a black hole, and nothing can get INTO white hole. As a result, it seems to be impossible to destroy a black hole... But similarly, it would also be impossible to create a while hole.


Do white holes blow?

White-holes are a theoretical hypothesis that they are the opposite of a black-hole, in which case they would push matter out into space yes.


Why are black holes round?

Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.
