Stephen Hawking has claimed that a black hole and a white hole are equivalent - the "black hole" assimilating matter, the "white hole" Hawking-radiating particles, black and white being both one and the same.http://www.quantumdream.net

Another interesting but less likely idea is that a white hole is simply a black hole viewed in reverse time. Watch a black hole in reverse time, and nothing can ever enter it.This seems unlikely to be the case, however, because objects approaching it would still follow hyperbolic paths, just like with normal gravity. I've been away for months, my physics has grown rusty...forgive me. I'm back, and I vow never to make that mistake again.

Ah! Mr. Hawkings Strikes again!"There was a young lady named Bright,
Whose speed was far faster than light.

Or perhaps,Black Hole---Einstein-Rosen bridge---white hole--- paraell universe or a distant part in the same or maybe the 10th Diemension. Turtle

Can you give me a source on this (Re: Hawking)?? I have looked a bit and can't find where Hawking ever held this position.

labguy 1970, see the last lines in the abstract of "Black Holes and Thermodynamics" by S. W. Hawking; Physical Review D, Volume 13, Number 2; 15 January 1976.http://www.quantumdream.net

I don't have a "source citation", but I thought that Hawking dumped that view since then; much like he dumped the (his) view about any necessity for singularities to exist. (?)

I said "no" but it depends on the black hole. If it is a wormhole, then it will have a white whole, but these wormholes are hypothetical."Sciences are the laws by which God set the universe."

Here is the abstract by Stephen Hawking:
A black hole of given mass, angular momentum, and charge can have a large number of different unobservable internal configurations which reflect the possible different initial configurations of the matter which collapsed to produce the hole. The logarithm of this number can be regarded as the entropy of the black hole and is a measure of the amount of information about the initial state which was lost in the formation of the black hole. If one makes the hypothesis that the entropy is finite, one can deduce that the black holes must emit thermal radiation at some nonzero temperature. Conversely, the recently derived quantum-mechanical result that black holes do emit thermal radiation at temperature kappa [h-bar] / 2 pi k c, where kappa is the surface gravity, enables one to prove that the entropy is finite and is equal to c3A / 4 G [h-bar] , where A is the surface area of the event horizon or boundary of the black hole. Because black holes have negative specific heat, they cannot be in stable thermal equilibrium except when the additional energy available is less than 1/4 the mass of the black hole. This means that the standard statistical-mechanical canonical ensemble cannot be applied when gravitational interactions are important. Black holes behave in a completely random and time-symmetric way and are indistinguishable, for an external observer, from white holes. The irreversibility that appears in the classical limit is merely a statistical effect.

To much relativity can squash your head!!
Universe is far more and in a lot more different way - simple.In this present crysis situation,Goverment is not the solution of our problems-Goverment is the problem

You've got it wrong. It's supposed to be: There once was a lady of wight,
whom traveled much faster than light.
She departed one day
in a relative way,
and returned on the previous night. ==================
