Abstract

It is shown that all gravitationally bound systems - stars, galaxies, and clusters of galaxies - are positively charged and have a charge-to-mass ratio of the order of 100 coulombs per solar mass. The freely expanding intergalactic medium has a compensating negative charge. The immediate physical consequences of an electrically polarized universe are found to be extremely small.
