| dc.description.abstract | It is shown that uncertainty principle prevents simultaneous, exact measurement of the expansion factor S(t) and its time derivative Ṡ(t) in a FRW universe. We compute the uncertainties in these parameters in the semiclassical limit. It is shown that (i) there is a minimum uncertainty ΔlH in the Hubble distance lH(t)=(Ṡ/S)−1 in a semiclassical universe. (ii) this uncertainty is amplified to an unacceptably large value if there was an inflationary phase in the early universe. | en_US |
