Exploring the BB Paradox in an Evolving Universe

[QUOTE="Simon Bridge, post: 5484728, member: 367532"] The argument is about proportions, not numbers. If something is 10x more likely that something else, then there will be 10x more of it than the other thing on large scales ... like across infinite expanse. If there are 99x more rocks than tress, then even if there are an infinite number of rocks and an infinite number of trees, the chance of picking something at random and finding it is a tree is still 1%. The argument does not say that no universes could have emerged from the surrounding metaverse but that we are massively unlikely, collectively, to be one: given 6-7billion known intellegences, some (almost all of them) should be bolzman brains but none are. I fact we have good reason to believe that we are not produced by a random fluctuation and the odds against all that evidence having just popped out of nowhere a few seconds ago is... well... it's not strictly impossible, and we'd have no way to tell if it had. But... Occam's razor. Another look ... and a statement about what it is supposed to disprove.
