After three months of experiments in a basement laboratory in London, scientists can confirm – with more confidence than ever – that the electron is very, very round.
In the most exquisite measurements yet, researchers declared the particle to be a perfect sphere to within one billionth of a billionth of a billionth of a centimetre. Were the electron scaled up to the size of the solar system, any deviation from its roundness would be smaller than the width of a human hair, the team said.
