A minority of astrophysicists has been unconvinced that the cosmological redshifts are associated with a universal cosmological expansion.

They were leftovers from the primordial hot universe, wrinkles that even the universal expansion had not ironed out.

We also have rough measures of the deceleration rate of the universal expansion.

Eventually the universal expansion of space-time will slow to a halt.

The Islamists of Minya refused to accept the universal expansion of Western civilization and were trying to change the map.

This'energy fueled the universal expansion.

But there seemed to be nothing like a simple Hubble shift, the rate from a universal expansion.

Hubble demonstrated that all galaxies and distant astronomical objects were moving away from us, as predicted by a universal expansion.
