Remember, macro-quantum vacuum coherence hides random micro-quantum zero point vacuum energy under the rug. Any random zero point energy that leaks out is exotic vacuum that contributes to the cosmological constant either as dark energy or dark matter depending on the sign of the pressure negative or positive respectively. Dark energy at a distance is a universal repulsive antigravity field. Dark matter at a distance is a universal attractive gravity field. Both fields can be stronger than what is expected from Newton’s constant. That is the effective Planck energy is smaller than 1019Gev. However, as possibly in the case of Ken Shoulders “charge clusters” the effective forces inside an extended exotic vacuum region can change sign! Indeed, that is why the EVO is stable and that is alsowhy the single electron is stable.
