*If by "flat", you mean mathematically flat, like a plane

universe extending infinitely in all directions. AG*
All that's "infinitesimally tiny" is the visible universe.
You must know that the Friedmann equation just defines the
dynamics of a scale factor, not a size.
*Are you claiming the visible universe at the BB was
infinitesimally tiny, but the non visible part was infinitely
large (mathematically flat), or huge (asymptotically flat)? AG *
*Bruce says the universe is always flat if k=1. *
k=0
*How can it be everywhere flat if there's a region which is infinitely
tiny; hence not flat in the visible region? *
?? How does a region being tiny keep it from being a tiny region of
something flat?

*How are we to imagine this? TIA, AG *
