It seems many people in Science have gravitated towards some form of a multiverse. Whether it's a Cyclical Universe or some version of the Many Worlds Interpretation. The question is where's the evidence? I do think there's some evidence that points to this conclusion. If you look at the work of Laura-Mersini Houghton a Cosmologist and Theoretical Physicist from UNC, she has amassed some interesting work in these areas. She basically takes the landscape of String Theory of 10/500 false vacua that are entangled and she applies the quantum wave function across these vacua. She says signatures of this entanglement should be found in our universe because information about this entanglement could never be lost. When Decoherence occurs some of these vacua inflate into universes and some don't but they carry signatures of their initial state of entanglement. Here's more: http://en.wikipedia.org/wiki/Laura_Mersini-Houghton Here's her original paper called Cosmological Avatars of the Landscape II: CMB and LSS Signatures http://arxiv.org/abs/hep-th/0612142 Here's a video where she goes over the evidence and she talks about how Planck's Satellite has confirmed some of her predictions. http://iai.tv/video/how-to-find-a-multiverse So we have predictions confirmed by observations, what's missing?
