Cosmological consequences of a classical finite-sized electron model

For a finite-sized classical electron, energy conservation requires that the Born self-energy UeBorn, due to the electric field which surrounds the electron, be added to the electron's rest mass energy mec2UBorn e, which scales inversely with the electron radius Re, is very large and, in fact, would dominate all other energy contributions within the intergalactic medium (IGM). By taking into account the ionization fraction.e of atomic hydrogen in the IGM Dark Energy can be quantitatively explained using UBorn e without the necessity of a cosmological constant Lambda.
