What's the evidence that multiple universes may exist? I used to think this was just metaphysics, until I saw this from wikipedia:
Multiverse - Wikipedia, the free encyclopedia
"Multiverses have been hypothesized in cosmology, physics, astronomy..."
Really? Is there some sort of scientific legitamacy to multiple universes?
