Oh sure, I have no problem with understanding the expansion of space.
I was thinking about whether other types of expansion like Sam5's explosion would look the same to the observer (one that isn't in the center).
For a constant speed expansion (initial impulse given at the "explosion") I figure they would... geometrically, in an Euclidian space. I'm not sure how exactly the low speed of light would mess with the observations. Plus there's still the problem that higher speeds would have to be more common than lower speeds to result in the observed homogenous distribution of matter.
