first to
discover that
distant galaxies are
redshifted, thus
providing the

galaxies are
observable above and

redshifted in
accordance with the
Hubble flow,
indicating that they are receding...

increasing number of
galaxies will
become extremely redshifted due to
ongoing expansion, so much so that they will seem to disappear...
