Cosmic acceleration in Regge-Teitelboim gravity
arXiv:2202.09453 · doi:10.1088/1361-6382/ac813f
Abstract
The Regge-Teitelboim formulation of gravity, which utilizes dynamical embeddings in a background space, effectively introduces source terms in the standard Einstein equations that are not attributable to the energy-momentum tensor. We show that for a simple class of embeddings of the Robertson-Walker metric, these source terms naturally generate cosmic acceleration.
