The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to elude us. Now, a new study by Anjun Chu and colleagues has examined ...

A collaboration between researchers in the US and Germany has made a major breakthrough in optical nuclear clocks, achieving laser-based excitation of Thoria-229 in a non-transparent host material.

An optical lattice clock embedded in the curved spacetime formed by the earth’s gravity. Dynamical interplay between photon-mediated interactions and gravitational redshift can lead to entanglement ...

The European Space Agency (ESA) has launched one of its most precise science experiments to date — the Atomic Clock Ensemble in Space (ACES)—to the International Space Station (ISS). This is no ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

WASHINGTON — Researchers have demonstrated a new optical atomic clock that uses a single laser and doesn’t require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks ...

Time signals shifted by a tiny amount that only very sensitive users would find upsetting UPDATED A staffer at the USA’s ...

Atomic clocks will only see a loss of 1 second in accuracy over a period of 10 million years. They are used in multiple ways, including the GPS in your car. Now researchers have found a way to bypass ...

To measure time, you need a constant rhythm. For eons, the regular movements of the sun and moon have set the pace for all of life on Earth. But over millennia, humans have sought and found more ...

Craig has worked in automotive media for nearly 20 years, producing content for publications ranging from Autoline and AutoGuide to Roadshow by CNET and EV Pulse. Aside from writing, he’s also ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...
