TL;DR
This paper explores a brane world cosmology model where the electric charge varies over time, linking it to variable speed of light theories and discussing its cosmological implications.
Contribution
It introduces a novel approach connecting varying electric charge in brane world models to variable speed of light cosmologies through unit transformations.
Findings
Establishes a correspondence between varying electric charge and variable speed of light models.
Discusses potential cosmological implications of such variable charge models.
Provides a framework for analyzing varying fundamental constants in brane world scenarios.
Abstract
We study the brane world cosmology in the RS2 model where the electric charge varies with time in the manner described by the varying fine-structure constant theory of Bekenstein. We map such varying electric charge cosmology to the dual variable-speed-of-light cosmology by changing system of units. We comment on cosmological implications for such cosmological models.
