No time for cosmology: Decoding dynamics from static cosmological correlations
The beginnings of the universe are encoded in the statistical properties of primordial perturbations imprinted at the hot Big Bang. Our understanding of primordial cosmology comes from measurements of these imprinted spatial correlations. They form a static pattern, and its apparent lack of causality is elegantly explained by an earlier period of time evolution. This time evolution from very primordial eras of the universe can not be observed directly. For conceptual and practical purposes, a reformulation of cosmological perturbation theory in which time is emergent is of fundamental importance. We hypothesize that there is an intrinsic description of primordial fluctuations that only uses…
