From the New Scientist website:
The fate of the universe depends on how dark energy - the force thought to be driving the accelerated expansion of our universe - changes with time. If it increases without limit, it will eventually tear everything apart, destroying the universe in an event called the big rip. Now physicists Lauris Baum and Paul Frampton at the University of North Carolina in Chapel Hill are invoking this effect to explain how the entropy of our early universe might have been kept in check.
In their model, dark energy becomes very dense and sets the universe expanding at such a rate that it approaches the big rip. The universe tears into small patches that rush away from each other faster than the speed of light. But the destruction is then halted, as the density of dark energy becomes equal to the density of the universe. At this point, each patch crunches in on itself. "All the patches, of which there are a huge number, will separately contract into disparate universes," says Frampton. Each patch will then bounce outwards again, creating a new universe.
Cool.

blimey, i am not sure even they know what they are talking about.
Makes perfect sense to me. Reading the works of Phillip K. Dick helps considerably. :-)
Universe or Multiverse, if there is no God you still have a meaningless life. Neener neener neener ; )
Hey, I'm actually at work today, so that's a step in the right direction, but still feel a rather low. I'll try to collect some intelligent thoughts as soon as I get some time and post them over at the metaphysical rodeo. We are really getting down to some bedrock issues it would seem.

Oh goody - I love fairy tales and this one's a real beaut. The anti-matter goes out of control and only the Doc can save us, with the help of Zoe.
