Is dark energy from cosmic Hawking radiation?

High Energy Physics - Theory 2010-03-02 v5 Astrophysics

Abstract

It is suggested that dark energy is the energy of the Hawking radiation from a cosmic horizon. Despite of its extremely low Gibbons-Hawking temperature, this radiation could have the appropriate magnitude O(MP2H2)O(M_P^2 H^2) and the equation of state to explain the observed cosmological data if there is a Planck scale UV-cutoff, where HH is the Hubble parameter.
