Here's the way it was explained to me a while ago.

First let's imagine that the universe IS infinite. This allows us to 
extend some axis from where we are, headed in some direction, which will 
never end. Now, what I plan to do is to put a small stone at every mile 
along that axis, starting from where I'm standing (where I put a stone 
marked A). The one a mile away is B, the one two miles away is C, the 
one 25 miles away is Z, the one 26 miles away is AA, and so on.

Now I come back in a year and I notice something odd. A is still right 
where I'm standing, but B is now 1.01 miles away, C is now 2.02 miles 
away, D is now 3.03 miles away, Z is 25.25 miles away, etc. Notice that 
B and C are now 1.01 miles apart, C and D are too, just like A and B 
are. So it's like everything that was a mile apart a year ago is now 
1.01 miles apart. I wait another year, and now B is 1.02 miles away, C 
is 2.04 miles away, Z is 25.50 miles away. So in the second year, 
everything moved another 0.01 miles away from their neighbors. Keep in 
mind this applies for the WHOLE INFINITE AXIS.

Hmmm, you say, so what if I had placed the stone years ago? What would 
it have been in the one year beforehand? Well, B would have been 0.99 
miles away, C would have been 1.98 miles away, Z would have been 24.75 
miles away. So the further away the stone is, the faster it seems to be 
moving relative to A. This extends ALL THE WAY out, even beyond the 
point where the speed relative to A is the speed of light. The speed of 
light just determines the size of our observable universe, not the size 
of the universe.

Now, it's a simple matter to clock backwards, and you'd quickly figure 
out that 100 years ago, B was right on top of A. But C would have been 
right on top of A too! It's twice as far away today but moving twice as 
fast too. And if you take any other stone you like, you'd find that it 
was right on top of A 100 years ago. Since this applies to all stones on 
the whole infinite line, this means that 100 years ago, the whole 
infinite line would have been at one and the same point.

It seems counterintuitive that an infinite thing could be traced to a 
single point at a finite time in the past, but it's hard to dispute the 
argument from above.
