elds in global de Sitter space is shown to be unstable to small perturbations, even for a massive free eld with no self-interactions. There are perturbations of this state with arbitrarily small energy density at early times that is exponentially blueshifted in the contracting phase of ‘eternal’ de Sitter space, and becomes large enough to disturb the classical geometry through the semiclassical Einstein eqs. at later times. In the closely analogous case of a constant, uniform electric eld, a… CONTINUE READING
