Peter I happen to think the Universe is infinite in time and the other dimentions... only because I cant imagine it floating in a sea of "nothing" I certainly dont think the Universe stops where our observations sign off.
The expanding of space is the point to get ones head around. Galaxies in their space as Andrew said may have the same speed in that part of space as we do but the point is the space between us and them is expanding... er but I am not sure of that either but thats the popular thought as I read it.
People say well how can we have them travelling faster than light..well they are not in fact it is the expansion of space that accounts for seeing them travelling so fast...mmm I think thats it. Observations support this idea or theory possibly a better way to put it a theory being really almost an established fact in this context an idea being an unsupported notion. Big bang is a theory gravity rain is a notion or an idea.Bail me out someone if I have anything wrong or if you think you can add clarity please. But Andrew has realy said that.
