Define Universe. Hubble Volume obviously finite. Current inflationary cosmos likely infinite in space but not in other dimensions. Entire substrate the cosmos comes from likely infinite along many more dimensions.

Agree with the first part of your comment but this last part... There's no experimental evidence whatsoever for other dimensions besides 1 time + 3 space so this is extremely speculative.
I mean, Time might be infinite, but it is bounded at least on one side and I suspect it's not bounded on the other.
In any case no one has evidence even for infinite space, for all we know it stops dead a Planck Length beyond the Hubble volume. Though this would require uh...extensive revision...of current models.
As for other dimensions, I'm using the term in the loosest possible sense to mean the substrate the current cosmos came from. It could have come ex Nihlo, of course, but it seems more likely it's part of a greater structure.
