The Quantum Echo of the Early Universe
arXiv:1501.05682 · doi:10.1139/cjp-2014-0567
Abstract
We show that the fluctuations of quantum fields as seen by late comoving observers are significantly influenced by the history of the early Universe, and therefore they transmit information about the nature of spacetime in timescales when quantum gravitational effects were non-negligible. We discuss how this may be observable even nowadays, and thus used to build falsifiability tests of quantum gravity theories.
