More accurate strontium-based atomic clocks are possible – and accurate to one second every 40 billion years – by emitting radiation in the visible, rather than microwave, spectrum.

It’s the creation of Alexander Aeppli, a graduate student researcher at the University of Colorado Boulder. For years, Aeppli has been tweaking to perfection an atomic clock that relies on ...

The world’s most precise atomic clock has confirmed that the time dilation predicted by Albert Einstein’s theory of general relativity works on the scale of millimetres.

Ekkehard Peik, one of the field’s pioneers, says such a clock could be a factor of 1,000 times better than today’s standard atomic clocks. In atomic clocks, the electrons around an atom’s ...

Just like an old-fashioned grandfather clock, which uses a pendulum to measure time, atomic clocks use the very regular and measurable oscillations of caesium atoms—9,192,631,770 of them make up ...
