How the vacuum rescues the Lorentz electron and imposes its Newton and geodesic motion, and the equivalence principle

In 1901, Lorentz models depict the electron as a uniformly charged, non-spinning spherical shell in classical electrodynamics. This model suffers from Coulomb repulsion between the like charges and a discrepancy between the kinematic and electromagnetic mass, the “problem 4/3”. In 1905, Poincaré solves both issues by incorporating vacuum energy with its negative pressure. Recently we proposed that vacuum energy can flow and condense, and act as an essential player in the interiors of regular, charged black holes, and in dark matter physics. That approach solves the above problems for the Lorentz electron with any spherically symmetric charge distribution. The point-particle limit produces the standard point-particle Lagrangian. This implies Newton–Lorentz motion, geodesic motion and the equivalence principle.
