Relativity and Cosmology


Entropy Growth in the Early Universe , DM Models , with a Nod to the Lithium Problem

Authors: Andrew Beckwith

We outline how DM density profiles may be perturbed by entropy generation, and that in part due to relic graviton production. The interaction of gravitons as an entropy generator may influence relic neutrino and neutralino production, which would affect not only DM behavior, but in certain situations the relic abundance of Lithium in the early universe.
