George Ellis – Are there multiple universes?
So, back to Brighton and a sweltering office on Sussex University Campus. I made it back to pick up the list of names I’ll be reading out at tomorrow afternoon’s graduation ceremony in time to give me a few hours’ practice tonight. On the train back from Cardiff I remembered a discussion I had at the conference last week, especially about the various views about cosmology, especially the idea that we might live in a multiverse. I did a bit of a dig around and found this nice video of esteemed cosmologist (and erstwhile co-author of mine) George Ellis talking about this, and also about his favourite kind of universe (namely one with a compact topology).Follow @telescoper
