At first guess, the speed slowed down because the mass of the universe was still
close enough that gravitational attraction was in excess of the expansion
pressure for a while, enough to slow down the rate of expansion, but not enough
to stop or reverse it completely before the universe expanded enough to allow
the expansion forces to exceed the gravitational attraction ...
