What is the origin of separated electric charges in the Universe ?
One origin is well known: all bodies in the Universe are hit by strong photons and particles of the cosmic rays. Especially the clouds from which stars are born have a high surface which is hit by strong ultraviolett photons of young stars in the proximity. Most of the ejected electrons return to the cloud, but a small fraction of electrons leave the cloud forever due to the electrostatic escape velocity. H II clouds in quick expansion come into existence. Neutral clouds i.e. H I -clouds will be ionized to H II clouds. Also protons are ejected by the same particles, but their mass is 1836 times higher than that of the electrons, therefore their ejection is negligible. Therefore, negative clouds i.e. “H 0”-clouds do not exist. Nature has an asymmetry in this case. Stable positive ions exist but stable negative ions do not exist. Another process of the separation of the electric charges is stronger but less known: the emission of the stellar wind (Birkeland 1896, Biermann 1950s, Koertvel
