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.
