the claim that "there is no such thing as a physical
infinity" is a relatively recent "physical truth". As late as the
1960's, a cosmology consisting of an infinite, steady state universe
was still being debated.

The standard flat big bang model is spatially infinite and temporally infinite (in the future). There are viable cosmologies that are temporally infinite in the past as well. General relativity and the standard model are both based on the continuum. There is as yet no empirical reason to believe that the universe is in any sense finite.
