“The scenario of many unobserved universes plays the same logical role as the scenario of an intelligent designer. Each provides an untestable hypothesis that, if true, makes something improbable seem quite probable.” -- Lee Smolin, The Trouble With Physics, 2006, page 164Lee Smolin compares the untestable explanatory power of MV vs ID not so much with regard to Evolution, but, more in general, with the unquestionable and eerie fine tuning for life of virtually all the physical constants of this universe in which we indisputably live.
Why should we assume at all that, "beyond the event horizon", there are "multiple universes", if not for the obvious reason that out of the roulette of as many as 10500 of them (the exorbitant figure —apparently drawn from "string theory" and/or "M-theory"— is provided by Stephen Hawking, among others) surely the existence of one so appropriately fine-tuned for life, nay, for intelligent life, becames "possible", even "probable"?
As we cannot realistically account for the eeriness of fine-tuning for intelligent life of the ONLY universe that we can experience, we invent a host of "universes" that, even in principle, we will never be able to experience, because they are ... "beyond the event horizon" ...
... how convenient ...
