In spite of this, he mentioned, that the fine tuning parameters can vary between distinct universes. If this is the case, then it is likely that we would never be able to detect those universes (even if they were right under our noses), because we are attuned to only our permutation of the fine tuning parameters.
This would suggest that even if they existed, they might as well not be real to us .. as they could never interact with us ... nor us, with them.

Craig,
I think in the video, Brian does an analogy of multiple universes as the slices of bread in a loaf. Somewhere in that, he mentions that if two particle were slammed together and we couldn't account for some lost energy, that perhaps this lost energy could have ended up in another universe, an adjacent slice of bread. It may be possible that these universes could interact but how you would verify or measure this is another puzzle.
