Coulomb's Law at Very Short Distance Scales

  1. Sep 30, 2009 #1
    I read in the Feynman Lectures, section 5-8 in Volume 2, that Coulomb's law may begin to break down at distance scales shorter than 10^-14 cm.

    Feynman says that, at the time of his lecture, the question was still open. Does anyone have any new information on this question?

    Coulomb's 1/r2 Law breaks down at distances shorter than an electron Compton wavelength (~3.8 x 10-11 cm) due to charge renormalization (Uehling equation). This renormalization has been known since about 1935. Are you talking about something else?

    Is there a simple explanation to this break down?

    Best regards,
