Abstract

Considering the observed anisotropy in cosmic microwave background radiation ($\Delta T/T \leq 10^{-4}$) an upper limit on the electric charge asymmetry over a cosmological scale is found which is several orders more stringent than those found earlier. The same argument constrains the charge of massless, degenerate neutrinos.
