Some random thoughts on Xar's thoughts. Not sure how connected they are.
-I'm not sure it makes sense to even hypothesize about a universe that is like ours in all ways except for, say, the speed of light. I doubt any change could be made to c without changing the universe beyond recognition. Nor do I think black holes and super-heavy neutron stars could exist without any stars; if the laws changed so that stars couldn't exist, I assume black holes and neutron stars couldn't either. It's kind of like the question of a planet just like ours that has life just like ours, but with maybe lizards being the intelligent species. But that couldn't be, because if evolution there followed the same path close enough to have all other things the same, it couldn't have changed that one point.
-I've often wondered along similar lines as Xar. Actually, while I don't feel it's conclusive, this type of thing is one of the reasons I don't think there isn't a creator. I think what I'm about to say is a different idea than the above paragraph, so I'm not contradicting myself. (Although I may be wrong, so feel free to argue the point.
) (Oh yeah, and this is obviously from a no-creator pov. heh) It seems possible to me that all the natural laws could have been the same as they are now, but the force of the Big Bang could have been slightly stronger. I mean, we don't know anything about the conditions the instant before the BOOM. Why did things not explode in a perfectly uniform spread? (Not sure how to word that.
) Why did it happen at the exact instant it did, instead of an instant - or an eon - earlier or later? And could it have exploded with .0000000000001% more force? What I mean is, could the exact same ultimate building blocks (whatever they are. Gluons? Strings?) that the BB created have been formed, but moving away from each other .0000000000001% faster? Because if that is possible, then gravity wouldn't have been able to pull any of them together. Not even two of them. And in that case, life certainly couldn't have come about. Individual ultimate building blocks that don't interact in any way couldn't form life. (And if the explosion was that % weaker, it might have all collapsed back to the singularity before life ever came about, and would have happened by now anyway.)
-The ultimate building blocks, and all laws, could be very different from the way they are, and intelligence of some sort could have come about. And that intelligence could be having the same discussion we are now having.
