Abstract

If we average over sufficiently large scales—on the order of 100 Mpc—our universe is homogeneous and isotropic to a high degree. We can therefore study what the Einstein equations tell us about the scale factor a(t) of the FLRW metric. But before we do this, we want to find out what we can infer about the time dependence of a(t) from ordinary Newtonian dynamics.
