World's first thorium-229 nuclear clock shows potential for ultra-precise timekeeping and fundamental physics tests.
Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the precision of atomic clocks. Scientists are developing next-generation atomic ...
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 ...
Is Einstein's assumption about gravity and time correct? Researchers want to find out with the help of two clocks. And send ...

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 ...
New thorium-229-based time standard reaches 1-second drift in 3 million years and promises compact, robust optical clocks ...
In popular culture, lasers are often portrayed as portable blasters that superheat whatever they hit. Some lasers do deliver tremendous amounts of energy in reality, but for scientists and engineers, ...
