Karl, Alex's dear departed boyfriend, may be a nod and a wink to yet another physicist by TPTB! I have been reading again and found some very interesting information about Karl Schwarzchild. He was a pioneer of a black hole theory that said a black hole is attached to a white hole by a wormhole. Boy, if that doesn't sum up our little issue here, I don't know what would! Anyway, if you're interested here's some of the science mumbo-jumbo about what he said:
The Schwarzschild metric admits negative square root as well as positive square root solutions for the geometry.
The complete Schwarzschild geometry consists of a black hole, a white hole, and two Universes connected at their horizons by a wormhole.
The negative square root solution inside the horizon represents a white hole. A white hole is a black hole running backwards in time. Just as black holes swallow things irretrievably, so also do white holes spit them out. White holes cannot exist, since they violate the second law of thermodynamics.
General Relativity is time symmetric. It does not know about the second law of thermodynamics, and it does not know about which way cause and effect go. But we do.
The negative square root solution outside the horizon represents another Universe. The wormhole joining the two separate Universes is known as the Einstein-Rosen bridge.
If you go to the site there's a neet picture and more interesting stuff:
