Whiteholes and the fact that none have been found

[LabRat1]

So according to "everything in this universe has something which is same in magnitude but opposite to its nature" Blackholes have whiteholes. But there is no scientific evidence to prove such a thing. Now if we say that blackholes have an immense amount of gravity, then whiteholes should have an immense amount of antigravity(?)(lets repel everything and everyone!!). Is this why none have been found?

Wouldn't the opposite of a black hole be just a plain void?

Well wiki says that BlackHoles suck, so Whiteholes must vomit.

Is there any reason to think that is the case?

Probably because they don't exist.

Isn't this the case assumed when thinking about the cosmos as a whole?

I don't think so. Can you give an example (other than white holes )

[mistermack]

If a black hole is a bottomless well that sucks in matter and energy, the opposite would be something that expels all ANTI-MATTER and ANTI-ENERGY.

How could anybody tell if they were next to a white hole? It would have expelled everything by now.

And how could anything get in there in the first place?

Wouldn't the light emanating from them be caught in our cameras or telescopes?

Maybe whiteholes are stars themeselves . Cuz' you know, they expel light and stuff.

"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 escape. White holes appear in the theory of eternal black holes. 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.^[1] However, this region does not exist for black holes that have formed through gravitational collapse, nor are there any known physical processes through which a white hole could be formed. No white hole has ever been observed.

 

"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^{[citation needed]} (though in the case of the maximally extended Schwarzschild solution, discussed below, the white hole event horizon in the past becomes a black hole event horizon in the future, so any object falling towards it will eventually reach the black hole horizon). Imagine a gravitational field, without a surface. Acceleration due to gravity is the greatest on the surface of any body. But since black holes lack a surface, acceleration due to gravity increases exponentially, but never reaches a final value as there is no considered surface in a singularity."

Black holes build athoms from light otherwise today there'd be no athom to produce light!

So there's no white hole because stars are the answer, and black holes energy'd come from big bang(speed).

Do they? Do you have a reference or evidence for that?

An opinion.

There're a lot of questions

- Where'is the light going?.......

- How much matter has been transformed into energy till now?!.....

 

An asnwer is there's a cycle: athoms ⇔energy

[Daecon]

So a white hole would be like a bubble or membrane that only allows for one-way passage, that is, light and energy can pass through to the outside but not pass through to the inside?

 

What would happen when there's no longer any mass or energy inside the bubble? Would the void on the inside combined with CMBR pressure on the outside cause the bubble to shrink into nothingness, which is why we can't detect them?

 

Any old white holes would have been emptied and crushed to nothiness from the pressure of regular space by now, and so until we can come up with a hypothetical way for them to be created, there's no evidence to suggest new ones are being made any more.
