Russell
"Hence there can be no such thing as a positively charged mass or a negatively charged mass. All charging masses are simultaneously discharging and all discharging masses are simultaneously recharging other masses in this two-way universe of motion. Energy is kept continually moving between the high pressure hot points of gravitative centres and the low-pressure cold areas of the evacuated fields which surround all masses." [Russell to NYT - 1930 November 2]
