  We show that if photon possesses a tiny but non-vanishing mass the universe
cannot be electrically neutral. Cosmological electric asymmetry could be
generated either at an early stage by different evaporation rates of primordial
black holes with respect to positively and negatively charged particles or by
predominant capture of protons in comparison to electrons by heavy galactic
black holes in contemporary universe. An impact of this phenomenon on the
generation of large scale magnetic fields and on the universe acceleration is
considered.
