View Full Version : Black-Holes and White-Holes

Okay... a black-hole from what I remember is a quantum singularity. An area in space so dense with such an intense gravitational field that even light cannot escape.
Some people have debated whether information was destroyed in a black-hole. And there is evidence to suggest even black holes break-down and "evaporate".
There also are white holes allegedly (according to a bit on NOVA which sounds questionable) where matter is deposited into our universe from elsewhere.
Now my question comes down to the conservation of matter and energy. From what I remember, energy and matter can be destroyed as long as energy and matter appears somewhere else at the same time from what I remember... it's probably this theory that makes "teleportation" seem / be feasible...
If matter was sucked into a black hole, and came out a white hole... was the information destroyed, and new information created at the same time? Or was the information sucked in, and expelled out of the white hole?

Totally whacked in the conversion - and that assumes white holes actually exist (mathmatically they can BUT none - or their logical output - have actually been found).

If the black hole/white hole are in different universes the answer is still NO since the information in the multiverse hasn't changed. No do white holes really exist? As has been pointed out they are mathematically possible but if Hawking radiation is true, I can't see how whiteholes can exist.

You raise a very good point fuelair. I'm not an astronomer but I wonder how a white hole would be detected. Black holes were located due to the violent "screaming" of matter disappearing into them. I wonder if white holes would excrete matter as violently? Only then would our instruments be able to detect them. I wonder if anyone is seriously searching the cosmos for them.

This theory was expressed on a Bermuda Triangle show yesterday. They said there ia a black hole in the Bermuda Triangle, and another at the bottom of the Marianas Trench. But there is a White Hole in between the two, so, here on earth, we have a conservation of matter. All that keeps the earth from being sucked away completely is that missing boats get regurgitated out the white hole into the center of the earth.
Inner Earth must have lots of cheap boats for sale...

I thought quasars had been posited as possible white holes. Red-shift data implies they're an incredibly long way away, and they're brighter than they "have any right to be".

Pretty sure that is no longer a consideration per:

Have you all read "A Complete History of Time" by Stephen Hawking? Seems many of you are speaking without a basic understanding of these things, and if you're not going to read an entire book in order to participate in a message board thread on the Internet, what kind of lazy, lazy person are you?

Thanks, fuelair! That's pretty fascinating.
From the description, I would imagine it would be even easier to find a white hole than a black holes as it would be pretty luminous (reflecting all light that "hit" it). Also, astronomers would probably notice some pretty strange trajectories.
With all due respect to the second law, I would really like these things to exist. I hate laws that can't be broken! :D

I did - a few years back (not the updated version though) - but I tend to keep up on net, Sci.Am and (less) Discov.

I once heard that Discovery was (partially) owned by the Church of Scientology.
Most likely nonsense ;-0

Thanks for the update, fuelair. I am just as stupid as I was, but at least I'm better educated. (Apologies to F.E. Smith)

What evidence exists to suggest this?

Because to me it sounds like a bunch of nonsense...
