Saurya Das, Mitja Fridman, Gaetano Lambiase, Elias C. Vagenas
TL;DR
This paper investigates how Quantum Gravity effects, specifically the Generalized Uncertainty Principle, influence cosmological equations and can explain the observed baryon asymmetry in the Universe.
Contribution
It introduces a novel approach linking Quantum Gravity modifications to the Friedmann equations with baryon asymmetry.
Findings
Quantum Gravity effects modify energy density and pressure in early universe.
These modifications can account for the observed baryon asymmetry.
Provides a new perspective on the role of Quantum Gravity in cosmology.
Abstract
We study Quantum Gravity effects in cosmology, and in particular that of the Generalized Uncertainty Principle on the Friedmann equations. We show that the Quantum Gravity induced variations of the energy density and pressure in the radiation dominated era provide a viable explanation of the observed baryon asymmetry in the Universe.
