Primordial density fluctuations generated by wormholes
arXiv:1906.03015
Abstract
We studied the influence of a wormhole existing in the expanding Universe and passing through the horizon volume on the energy density of the Universe. The two-point correlation function of a free massless scalar field mimicking the inflaton was found. The revealed violation of the translation invariance during the process in question might be potentially envisaged in the anisotropy in cosmic microwave background radiation map.
