Description
I will briefly review the basis for eternal inflation and
make the case of an important ingredient not previously
acknowledged - the space time homogeneity . I will
describe our proposal for the measure of eternal
inflation that includes both essential conditions, large
field fluctuations and smooth homogeneous domains, in
the self reproducing probability estimate. The new
measure is finite and does not violate unitarity.
However, due to the increasing inhomogeneities in the
background spacetime fractal, self-reproduction stops
within a finite time t_f, thus inflation can not be eternal.
