Abstract

The idea that dark energy is gravitational waves may explain its strength and its time-evolution provided that the additional energy comes from a background. A possible concept is that dark energy is the ensemble of coherent bursts (solitons) of gravitational waves originally produced by stimulated emission when the first generation of super-massive black holes was formed. These solitons get their initial energy as well as keep up their energy density throughout the evolution of the universe by stimulating emission from a background brane. We model this process by working out this energy transfer in a Boltzmann equation approach. The transit of these gravitational wave solitons may be detectable. Key tests include pulsar timing, clock jitter and the radio and neutrino backgrounds.
