Some Enigmatic Aspects of the Early Universe III

TL;DR

This paper explores complex aspects of the early universe, including dark energy, charge, magnetic fields, rotation, and extra dimensions, proposing connections with cyclic brane theory and constraining key cosmic parameters.

Contribution

It extends previous discussions by incorporating effects of charge, magnetic fields, rotation, and extra dimensions, linking them to cyclic brane cosmology and constraining related cosmic quantities.

Findings

Constraints on net charge and magnetic monopole density.

Implications for primordial magnetic fields.

Possible connection between extra dimensions and cyclic universe models.

Abstract

In the previous parts of the discussion on the same topic, various aspects of the very early universe were discussed. We discussed how inclusion of large dark energy term compensates for the net gravity. Here the discussion is taken further including the effects of charge, magnetic fields and rotation. The role of large extra dimensions under the extreme initial conditions is discussed and possible connection with the cyclic brane theory is explored. We constrain various cosmic quantities like the net charge, number density of magnetic monopoles, primordial magnetic fields, size of the extra dimensions,etc.
