the shear scale of the universe isn't something that we can comprehend, the fact that we don't even know what dark matter is proves that we know very little of what's really going on. but this is what makes the search interesting, there's always something new to look for.
edit, i just thought of this - if there was a big bang, why is there so much in the Hubble Ultra Deep Field? one would think that there would be less stuff the farther you go outward. so even if the stuff that we can observe is moving outward, we still can't say where it all started.
