By correcting Einstein's field equations and Maxwell's equations, most problems with singularities might be resolved.<br />Renormalization in quantum electrodynamics deals with infinite integrals that arise in perturbation theory. Such infinite integral might arise merely because Maxwell’s equations are incorrect at the Planck scale. Assume that leptons have structure at the Planck scale. I conjecture that, EVEN AFTER QUANTUM AVERAGING, Maxwell’s equations might be false at the Planck scale, because leptons have structure at the Planck scale. Let ρ represent the electric charge density (charge per unit volume). I conjecture that, in equation (19b) on page 23 of Einstein’s “The Meaning of Relativity” (5th edition), ρ should be replaced by the expression ρ/ (1 – (ρ^2 / (ρ(max))^2))^(1/2), where ρ(max) is the maximum of the absolute value of the electric charge density in the physical universe.<br />The preceding hypothesis makes the qualitative prediction that electromagnetic radiation emanating from sources near black holes might be unexpectedly large. M82 X-2 might be worth considering in this regard.<br /><a href="https://en.wikipedia.org/wiki/M82_X-2" rel="nofollow">M82 X-2, en.wikipedia</a>David Brownhttps://www.blogger.com/profile/10537922851243581921noreply@blogger.com
