Abstract:We investigate the propagation of electromagnetic fields and potentials in the plasma of the early Universe, assuming a Friedmann–Robertson–Walker background with negative curvature. Taking over results from classical plasma physics, we show that charged particles will acquire an effective mass that has not only the expected thermal component but also a non‐thermal component due to the influence of distant matter. Although this is a direct effect of the vector potential, we show the theory is nevertheless gaug… Show more
