No, the time constraint only limits the observable universe. The Big Bang
happened 13.8 billion years ago so the observable universe (for us) is a
sphere centered on the Earth with a radius of 13.8 billion light years, we
can look at 2 galaxies 13.8 billion light years away and 180 degrees apart
but neither can see the other because they are not in their observable
universe.

If the most popular version of the theory is correct (the inflation theory)
the Big Bang was just a time when for a very short instant space expanded
at an exponential rate. Perhaps space was finite when all this happened,
perhaps not.
