Re: EM, the Biot-Savart force law can result in long-range attractive forces proportional to d^-1 instead of d^-2. So if it’s operative at galactic and intergalactic scales (between plasma filaments) and we’re not fully taking it into account, then we may be discounting the most powerful long-range force in the universe.
