Inside a small metal box on a laboratory table in Vienna, physicist Markus Aspelmeyer and his team have engineered, perhaps, the quietest place on Earth. The area in question is a microscopic spot in the middle of the box. Here, levitating in midair—except there is no air because the box is in vacuum—is a tiny glass bead a thousand times smaller than a grain of sand. Aspelmeyer’s apparatus uses lasers to render this bead literally motionless.
