In a flat universe (k=0) and Lambda=0, the scale factor depends
on time according to: where t_H is the Hubble time, 1/H_0 and R_0
is the current scale factor.
a) Show that if an event is observed at redshift z, the age of
the universe was
b) Prove then that the current age of the Universe is

t(z=0)=2/3 th = Z H
on time according to: where t_H is the Hubble time, 1/H_0 and R_0
is the current scale factor.
