If the inverse Hubble time is 70 +/- 7 km/sec/Mpc,
then H_0^-1 is 14.0 +/- 1.0 Gyrs, very similar
to the age of the globular clusters. There is
little room for deceleration in such a Universe,
a far cry from the elegant asymptotically stationary
situation envisaged in the Einstein de Sitter model.
If the age of the globular clusters is 13 +/- 2.5
Gyrs with 95% confidence, then that model is ruled
out by the expansion rate constraint at a similar
confidence level.
This is an independent indication that the geometry
of the Universe suggested in the last few years
by fainter than expected high redshift supernovae
may be correct.
