Accelerating Universes from Short-Range Interactions
arXiv:gr-qc/0505105 · doi:10.1016/j.physleta.2005.10.030
Abstract
We show that short-range interactions between the fundamental particles in the universe can drive a period of accelerated expansion. This description fits the early universe. In the present day universe, if one postulates short-range interactions or a sort of "shielded gravity", the picture may repeat.
