In the case of flatness, if the expansion rate were constant, as defined by the Hubble constant of about 70 km/sec/mps, and assuming a hyperspherical geometry expanding for 13.8 by, the measured flatness is probably implausibly too close to zero; IOW too flat. Inflation might be the explanation. AG -- You received this message because you are subscribed to the Google Groups "Everything List" group.
