A new mechanical “clock” has been created by an international team of researchers, led by scientists at the University of St Andrews, which could test the fundamental physics of gravity.

The levitated mechanical oscillator, created within a glass sphere the size of a single blood cell, was manipulated by light by the team to create an ultra-sensitive sensor which could measure temperature and pressure changes at the nanoscale.

This highly accurate clock could potentially detect gravity at smaller scales than previously possible and find potential evidence for deviations from Newton’s laws of gravity calling for new physics beyond what we currently understand…If this was actually a clock, it would be so accurate that it would only have lost half-a-millionth of a second in a whole day.”

I winder if Jeff Bezos knows about this clock, yet? Bet he’d want it for his collection, his research.
