Initial conditions problem in cosmological inflation revisited
arXiv:2304.12150 · doi:10.1016/j.physletb.2023.138028
Abstract
We present first results from a novel numerical relativity code based on a tetrad formulation of the Einstein-scalar field equations combined with recently introduced gauge/frame invariant diagnostics indicating that inflation does not solve the homogeneity and isotropy problem beginning from generic initial conditions following a big bang.
