Does it have a radius or not? If yes, then what is it? If no, then why does it (seemingly) not curve space-time to the point where it's discontinuous at the electron's center (an infinate potential)? If the answer isn't a yes or no, what is the probability distribution of radii as a function of radial distance? What is the substance that makes up the electron? Is it a group of matter waves bounded by one unit of charge? if it's made of three quarks, how does that work? what forces hold the quarks together, do they have charge or mass? How much empty space is in the electron, if any? If it's a point, is it infinately dense? if it's infinately dense, wouldn't it have infinate mass, and infinate gravity? How does the standard model make such a daft claim that the electron is a point?
