Two questions, actually:
(1) Sure, the universe's expanding. But then we're part of that expansion, right? That is, our bodies too are expanding, aren't they? The distances/space between our cells, and therefore the size of our bodies, and also the size of our telescopes and whatnot? Does that not kinda sorta cancel out, then? That is, vaster spaces will obviously expand vastly more, but the proportionality of it? (Well, clearly that isn't how that works, I guess. We wouldn't even be talking about an expanding universe otherwise. But I was wondering why not.)
(2) Does everything expand? Even at the teeny-tiny quantum scale? Or is it only at the 'regular' scale, where QM doesn't directly come in? (So that, as far as our bodies, is it only our the distance/space between our cells that's expanding along with the expanding universe; or would that expansion apply also to inter-molecular space/distances, maybe even sub-atomic space/distances?
