The electron is so round that it’s ruling out potential new particles
<i>The experiments are now so sensitive that if an electron were the size of Earth, they could detect a bump on the North Pole the height of a single sugar molecule.</i><p><i>This new bound is sensitive to energies above roughly 10^13 electron-volts — more than an order of magnitude beyond what the LHC can currently test.</i><p>Wow.
