I'll not argue that other theories are woefully incomplete. But Tegmark's bullet is fired so wide that I can argue that in some universe there MUST be an invisible purple rhinoceros. Heck I can even posit that in some universe Jesus Christ is actually my personal saviour, that Noah built a big boat, and that dinosaurs make the best stand-up comics. In Tegmark's view all of them are possible and therefore, given infinite possibilities, must be true somewhere.
I think in this particular universe Tegmark has taken a bit too much LSD. Hey and if not in this one in another one: Right? He explains nothing. He excuses everything. In Tegark's universe there is some place where pigs can fly and Snow White was really kissed by a prince. Impressive physics? I think not.
