Brent No. We build football fields, in stages, by increments. But it only becomes a football field at some moment. An infinite field cannot be built by finite increments. Not a close call. JC made the same claim in another thread, and we agree on this. A finite universe remains finite even if it expands. Likewise, an infinite universe remains infinite. AG You understand that, but you refuse to understand that our universe, assuming it's infinite as the evidence points, was infinite from the beginning and being infinite does *not* entail that it had to expand instantaneously...which you keep asserting. Brent The evidence you claim which seems to indicate an infinite universe is, IMO, underwhelming. It seems to indicate a flat universe, and thus infinite in spatial extent. However, there is a small error in the measurement, which is what one would expect if the size of the universe is exceedingly huge and and approximately spherical. Moreover, if we run the clock backward, ostensibly, the observable universe is smaller in the past than at present, and had a beginning as evidenced by the CMBR. Applying the Cosmological Principle, there's no apriori reason to assume the unobservable universe behaves differently. That is, smaller and finite, and will come into view as we go backward in time. OTOH, I do believe the underlying substratum from which our bubble emerged, is likely infinite in spatial extent.
