In (hypothetical) wormholes, can a black hole be connected to another black one?

Question

Or do they have to be a pair of black/white?

And how thing would be able to emerge from a endpoint black hole? As Hawking's Radiation?

Has a white hole ever been observed?

I stand to my words on the white holes - from the wikipedia: Lorentzian wormholes known as Schwarzschild wormholes or Einstein-Rosen bridges are bridges between areas of space that can be modeled as vacuum solutions to the Einstein field equations by sticking a model of a black hole and a model of a white hole together

Answer 1

this is actually a key point to a few theories.
We donot know what happens in a black hole.
Common sense says its a very very very compact spot of matter.
However, it does warp time and space. It does cause the space around it to experience severe frame dragging.
So it is possible that it could alter space time within its Event horizon. It has been postulated by a great many people that matter flowing in to a black hole could actually 'miss' but since it cannot escape where does it go? Hawkins wrestled with this many times and made one theory about it but then later retracted it after much debate. he lost an encyclopedia to this retraction due to a bet he had.
as for emerging as hawking radiation that would be E=mc2 being expressed. matter being turned into energy and radiating out of the edge of a black holes event horizon. As for the ultimate question if there is something on the other side of a black hole? Possibly. But seems counter-intuitive. But the universe is a bizarre and wonderful place.

Answer 2

Ive read all of Hawking's books, but Ive never heard of a white hole. A black hole is a collasped star with more than 3 solar (our sun) masses after the supernova, and cannot support its own gravity.

In theory, it is possible for wormholes to exist, but most likely only subatomic particles could travel through. I would like to say that our knowledge on this subject is comparable to cavemen learning about the internet.

In theory a wormhole (technically named Eistein-Rosen bridge) is 2 black holes that have been connected in some manner (hitting each other and inverting, or spinning, etc).

As far as we can guess, it is not possible to travel through a wormhole, as the destcutive forces of the black hole on either end would destroy you.

The reason we do not know much about them is because the laws of physics are different inside them, and we know nothing about it.

Is it possible that the white hole you mention is a quasar? Which is a completely unrelated concept.

Answer 3

i have not seen any work in the french literature that proves white holes exist but to relate black holes to wormholes is a little far out.

Answer 4

I don't think white holes exist, and black holes are something different from the traditional wormhole
