Cosmology driven by one-loop QED |
|
Abstract |
The one-loop semi-classical description of quantum electrodynamics is taken as a source of the Einstein field equations for a homogeneous and isotropic universe, in the limit of high conductivity which is expected to hold in the early era of our Universe. It is shown that a cosmic singularity (the standard big-bang scenario) is either present or not according with an arbitrary choice of accuracy. |
