Quantum physics makes small leap with microscopic gravity measurement

Scientists have detected the pull of gravity on the microscopic scale in a feat that lays the groundwork for probing its nature in the mysterious quantum realm.

In an experiment involving sophisticated superconducting apparatus cooled to within a whisker of absolute zero, and brass weights stuck to an electrical bicycle wheel, physicists recorded a minuscule gravitational tug of 30 quintillionths of a newton on a particle less than a millimetre wide.
