A new experiment involving a network of entangled atomic clocks could finally help us test how quantum mechanics fits with general relativity. Quantum mechanics is our best understanding of the ...

By using a rare thorium nucleus as a timekeeper, physicists have demonstrated the first working nuclear clock, a device that could lead to even more precise clocks and new ways to search for dark ...

But physicists have long dreamt of even better clocks that run on atomic nuclei, which are less sensitive to environmental disturbances. According to new research, that dream might soon become reality ...

For nearly 50 years, physicists have dreamed of the secrets they could unlock by raising the energy state of an atom's nucleus using a laser. The achievement would allow today's atomic clocks to be ...

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity. Now a new theoretical study pushes that weirdness into even stranger territory. It ...

The time is nigh for nuclear clocks. In a first, scientists have used a tabletop laser to bump an atomic nucleus into a higher energy state. It’s a feat that sets scientists on a path toward creating ...

Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a smartphone screen. Yet despite its constant presence, time remains one of the ...

The famed Michelson-Morley experiment of 1887, in which perpendicular beams of light were raced against each other, seemed to show that a light-carrying ether pervading all space did not exist.
