EndofMysteries:
what is past that point? That might be nothing
Well, yes. And that nothing might be an inherently unstable state, which would explain a thing or two and fit very well with some current scientific suggestions. Or the models might be wrong, or need adjustments. Anyway, my point still stands: Krauss' model does fit with what we know and extrapolates it to an area where we currently can't be sure. A viable rejection of his model needs to show that it is invalid for some reason, and the reason needs to be better than "I don't agree with him about 'nothing'", or it's just a statement of opinion.
Simply put, inserting a conscious and personal creator to solve the question of why nothing is unstable is a bit pointless, unless there are good reasons to attribute more elements of reality to this entity, and so far I have seen no such reasons. If they were to show up, I'd likely change my mind - again. :)
