at some point there had to be a first. Why? quote:
But one is a fact that every physical particle of the universe is moving away each other uniformly. Actually this isn't a fact, it is a supposition of some models of expansion. What we DO know is that everything is moving away from us. From that a theory of an expanding universe has been developed. However, since nobody really knows what the universe is like, we don't know how it's expanding. there are various models to choose from. quote:
It would be impossible to move on a curved path by uniform expansion. Yet apparently it does, at least according to some scientists. Finite space theory supposes space has no edge or end, because it wraps around on itself., just as Heather supposed. Look, the universe is weird, really, amazingly, mind-bogglingly weird. It works by totally separate set of rules that we barely understand. We know nothing for sure about how the universe actually works, or why. We have a lot of ideas, theories and models, but we don't know what is right.
