Well, I think I understand what they are saying...or at least what makes sense out of the report. My references are a bit old....from 25 year old cosmoloy, so Rich might correct me a bit, but since he hasn't answered here, I'll give it a try. The critical thing to point at is the evidence for dark energy. The acceleration of the expansion of the universe requires some force/energy behind it. It's unseen, and thus called dark energy. This allows some freedom in the definition of space after the universe expands for billions and billions of additional years. What I don't understand is how dark energy can cause symmetry to return to space....alowing for small patches of it to freeze and produce new universes. The advantage of these schemes is that there is real evidence for dark energy...so that parameter isn't just a free one. But, the theories like the one proposed are still minimally constrained...so we should expect a lot of different explainations to fit data.
