The Cosmology of an Infinite Dimensional Universe
  We consider a universe with an arbitrary number of extra dimensions, $N$. We
present a new method for constructing the cosmological equations of motion and
find analytic solutions with an explicit dependence on $N$. When we take the
$N\rightarrow\infty$ limit we find novel, emergent behaviour which
distinguishes it from normal Kaluza-Klein universes.
