Hello all!
I signed up to this site just to comment about this crazy BBC Horizon episode. (I can usually be found on the Ford Owners Club.

Monsieur Guffer & STEMO, you are completely correct. Not one shred of evidence, even though she said it was becoming self evident.
The quantum computer bit was interesting but out of date I think. The latest quantum computers can process "best route" type computations slightly more efficiently than a normal computer processor, but nothing of significance yet.
I personally think there may be some truth, but only in the quantum level and they are jumping to conclusions because of these quantum phenomena. Similar to the psudo scientists that jump to magical conclusions because of the implications of quantum realm.
Ironically, one of the biggest reasons for scientist insisting that multiverses "need" to exits is because the only other explanation for having a universe with exactly the right physical properties and laws for us to exist is to say that there is a god that made it that way.
Therefore there must be infinite universes that exist and we're just lucky enough to be in the once capable of creating planets of stable mass, supporting life in the goldilocks zone.
Monsieur, spot on with point 1... I'd like to ask that guy if he believes in free will or a deterministic one, and if so is that the necessary ingredient for branching off a new reality. If so, what level consciousness can do this, a human only, primate, or can a microbe's choice also do this?? It is almost laughable.
