"the scales are off by a hundred orders of magnitude"...“If inflation exists, the vacuum energy is contained on a larger scale than in our 'own' universe,”
Wholly crap! Dood, inflation sucks!
Seriously though, aren't a universe and a multiverse mutually exclusive? I mean if a universe is "all existing matter and space considered as a whole; the cosmos" then how can you have, presumably, multiple instances of it as a multiverse would imply? At least it's comforting to know that it's beer o'clock somewhen.
