On Axionic Dark Matter, Gravitonic Dark Energy, and Multiverse Cosmology in the Light of Non-Linear Electrodynamics

In 1972, Zeldovich proposed the methodology of the electron positron pair production which can be used to approach the Early Universe cosmology. In this paper, we first discuss this approach in relation to an upper bound of a minimum time length, which compared to certain recent graviton mass study, creates a productive cosmological scenario.

Namely, a non-zero graviton mass gives a non-trivial a minimum scale factor and for a temperature varying cosmological “constant” parameter leads to Quintessence. Afterwards, we first consider more representations of density, and then compare density in the case of certain strengths for the magnetic nonrotating universe. In other words, we involve the weak energy condition versus a more generalized point of view. Read more>>>>>>>>>>>>>>
