I read this book called How To Teach Relativity to Your Dog by Chad Orzel. In the book he discusses how an electron is known to have mass but is also considered a point like particle. He said that some interpretations consider the electron thus to have an infinitely dense mass which should generate gravitons, which gravitons should also have mass and thus generate gravitons. Thus this is quite a problematic interpretation. Other interpretations in quanum electrodynamics consider the electrons' aspect of the electrical charge in an infintesimal space so thus they should have infinite energy and this is problematic also though solved partially by having virtual particle - antiparticle pairs appearing and disappearing in the locality of the electron thus spreading the electron charge.thus avoiding energies with infinity values. Anyway my question revolves around shouldn't these supposed features of the electron resemble a black hole and its' singularity?? Myself, I thought there were a groups of physicists that found experimental or mathematical evidence that electrons were not point like but did possess some three dimensional spatial character? If all particles with mass are point-like then are they not microsingularities? What is the evidence that electrons and other particles are point-like?
