Tiny intrinsic time fluctuations could limit ultimate clock precision: Study
A study by physicists affiliated with the Foundational Questions Institute (FQxI) found that time ...
On Jan. 27, the Bulletin's Science and Security Board will reveal the 2026 Doomsday Clock time during a live, in-person news ...
A team of physicists has discovered a surprisingly simple way to build nuclear clocks using tiny amounts of rare thorium. By ...
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 ...
Since 1947 -- after the end of World War II and at the beginning of the Cold War -- the Science and Security Board of the Bulletin of Atomic Scientists have kept what they call a "Doomsday Clock." ...
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 ...
Atomic clocks have long been the gold standard for measuring time and frequency. Among them, optical clocks—using atoms like strontium or aluminum—have reached staggering levels of accuracy, with ...

This atomic clock keeps time for 15 billion years
The strontium atomic clock measures time so precisely it would not lose a second for 15 billion years, redefining how time ...
The white pickup truck pulls up to a decommissioned space observatory on top of Mount Blue Sky, one of Colorado’s famous “14ers,” mountains that reach more than 14,000 feet high. The scene is stark on ...
