View source for The Electron-Positron Sea

It is proposed that all space is permeated with a dense electrically neutral sea of electrons and positrons which serves as the medium for the propagation of light. The challenge remains to devise a stable bonding mechanism within this luminiferous medium that conforms with Maxwell’s equations by providing the necessary solidity and the physical mechanism that will give rise to the characteristics of electromagnetic waves, while at the same time allowing for the fluidity that would avoid the problem of friction in the planetary orbits.
