Comment Re:What about size? (Score 1) 150
The summary and articles are a little vague about what the "shape" of an electron is supposed to be. As are as we know, an electron is a point particle, meaning it has zero size. What these scientists mean by "spherical" is that the electron's electric field is perfectly spherically symmetric (measured to a higher degree of accuracy than any previous measurement). This means that if you imagine a sphere with an electron at the center, then the electric field of the electron is exactly the same magnitude over the entire surface of the sphere. If the electron had a dipole component, as many supersymmetric theories predict, then the electric field of the electron would be stronger on one side of the imaginary sphere. The scientists did not measure any dipole component.
