Electron, A Perfect Sphere

Scientists for decades have been trying to figure out the shape of electrons. Now they have made the most accurate measurement of its shape. They found that it is almost a perfect sphere. The experiment suggests that the electron differs from being perfectly round by less than 10-27cm. The team studied the electrons inside Ytterbium Fluoride. The results can help find antimatter, an elusive substance with particles having opposite electrical charge than matter.
