OK, I'll have a crack, but I'm not a scientist.
Say you were a 2 dimensional being (basically up and down did not exist for you) and you lived on a 3 dimensional sphere. You could travel forever in the 2 dimensions you existed in and never reach an end, only back where you came from.

This does not make the sphere infinite, just finite in a direction you cannot perceive or travel in.

So use that analogy for yourself as a three dimensional being (as you are) and the universe as a 4 dimensional sphere. It's not infinite, but in a direction we can't/dont 'do'.

This may all be bollocks.
