Feb, 2005Citations per year
Abstract:
We show that violation of the null energy condition implies instability in a broad class of models, including classical gauge theories with scalar and fermionic matter as well as any perfect fluid. When applied to the dark energy, our results imply that is unlikely to be less than -1.- gauge field theory
