*On the subject of expanding universe, most responses only addressed spatial
expansion.  We live in a four dimensional reality, with time being the fourth
dimension.  Is there also an expansion along the time axis?  In other words,
does time run slower today than yesterday?
     If so, can galactic redshifts be equally well interpreted as:
       1.  Atoms were smaller yesteryear, hence electron energy levels were
           different, spectral lines "redder" than today.
       2.  Time ran faster yesteryear, hence a photon emittted then would be
           interpreted today to be "oscillating" slower (i.e. lower frequency)
           hence redshifted.
