Is a Quantum Gravity Era Necessary?

Abstract

We present the first published framework of the entirety of cosmological history which is thoroughly classical (without any quantum-gravitational era or singularities) and which passes all the known extensive consistency checks on such a model, and discuss some of its possible cosmological implications, such as its ability to account for the matter-antimatter asymmetry, dark flow, and the Hubble tension, albeit at the cost of further assumptions.

(For the moderator: corrected two typos in section 4, "direction"->"dimension" and "neutrino"->"antineutrino")
