Coincidence Problem

Our universe seems to be just entering a phase of acceleration, perhaps
indicative of an ev-mev scale of physics. In this paper we suggest an
alternative mechanism where the current acceleration is not due to new
physics at ev scale but because of interactions between the dark
components. In this model we also show how one may be able to explain the
large hierarchy between the mass scale of current acceleration and the Planck
mass, by relating it to another `large' parameter, the number of
efoldings during primordial inflation.
