==Doest the multiverse hypothesis entail the existence of the Biblical God?== 
 I think it does, at least functionally. Here is why: According to Tegmark (who in the article is responding to all the criticisms of the multiverse) “all structures that exist mathematically exist also physically” (see Max Tegmark). But there exists a mathematical structure that describes a universe where a SAS (self-aware substructure – which for short we shall identify by “Yahweh”) creates a toy universe and plays with it making inscribed stone tablets to magically appear, burning bushes, parting the Red Sea, and so on. One can certainly mathematically describe such a universe. So according to Tegmark such a universe actually exists, and ours may be the toy part of it. Great – I can see the headlines “An MIT prof claims that Yahweh exactly as described in the Bible exists somewhere out there”.   

 My point of course is that any naturalistic hypothesis that entails the physical existence of Yahweh is just nonsense. The idea that anything that is mathematically describable is also physically actual is not strictly speaking logically impossible, but can fairly be called “the mother of all speculations”. After all what it really says is that anything not impossible is real. I mean take your pick: perpetuum mobile? It exists in many universes. A universe where planets are made of Swiss cheese? Of course. All of us living eternally and doing nothing but discussing Tegmark’s ideas? Sure, why not, actually this happens in more than 10^100 universes. A universe that consists of three kittens plus a copy of multiverse? Bertrand Russell must be starting to spin in his grave, but according to Tegmark that universe exists too.  

 Of course it’s easy to make fun of Tegmark’s idea, but to be fair the so-called Many-worlds interpretation of quantum mechanics, which is arguably the most popular ontological understanding of quantum mechanics among physicists today, implies similar nonsense as there are few phenomena that quantum mechanics actually prohibits – but at least quantum mechanics itself is constant in all baby universes there. On the other hand of course Tegmark’s multiverse entails the truth of the many worlds-interpretation in many universes that are just like ours. The mind spins.
