If gravity-causing mass is distributed densely enough; they say the expansion of the Universe may slow down.
Then reverse, as gravity pulls it all back together to a singularity (so big-bang in reverse). Your 'floor' is the original big-bang.

Or the Universe, whose expansion is known to be accelerating; might not collapse gravitationally.
