while i have no problem with the whole universe expanding thing, i have qualms with the balloon idea.
you take an uninflated balloon, draw a dot on it, and blow it up. as well as the balloon increasing in size, the dot does also.
if (ignoring the X^2/3 law :P) the human body was expanding gradually so proportions stayed the same, you wouldn't perceive your feet getting further from you, because they're getting larger as well. assuming no external reference, you'd never realize the expansion was occurring.
i guess what I'm tryna ask is: if space is expanding surely everything, objects etc, must be expanding as a consequence, so how can it be stated that "galaxies are moving away as a result of *the expansion*," because we'd never perceive it.
hope this makes sense
