Over the Christmas season of 2019, four physicists hovered over two minuscule gold orbs, each about the size of a ladybug, in a Vienna laboratory. It was silent, in all the ways you can imagine: audibly, seismically, even electromagnetically. It had to be, as the researchers were trying to detect the influence of one of the spheres gravity on the other.
Detect they did, in a first for gravitational probings at this scale. One of the golden balls (the source mass) was recorded wobbling the other…
