What are you thoughts about Laura Mersini Haughton´s theory of the multiverse? She predicted a CMB cold spot, power suppression at low multipoles, preferred direction associated with the quadrupole octupole alignment, dark flow, and the deviation of the CMB amplitude. While dark flow remains controversial, the other predictions have been confirmed. (See http://arxiv.org/abs/0809.3623 http://arxiv.org/pdf/0810.5388.pdf http://arxiv.org/pdf/hep-th/0611223v1.pdf http://arxiv.org/pdf/hep-th/0612142v1.pdf for more information) On the other hand, there are other interesting theories of finite universes.
