On Earth, knowing the time feels simple. Your phone pings the same second as a GPS satellite and an atomic clock in a lab.

Time is relative. If you don’t believe me, get into a plank for one minute. How was that? Longest minute of your life, huh?

This temporal lag is a direct consequence of Albert Einstein’s Theory of General Relativity. The rule is simple: the weaker ...

Summary: Time doesn’t flow uniformly across the solar system, and new research reveals just how differently it unfolds on Mars compared with Earth. By tracing subtle gravitational and orbital ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...

The field of optical atomic clocks, in combination with ultracold atoms, has transformed precision timekeeping and metrology. By utilising laser-cooled atoms confined in optical lattices, researchers ...

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency standard — ...

BOULDER, Colo. — Good news for people who are sticklers for punctuality: The National Institute of Standards and Technology has a new atomic clock that isn't supposed to gain or lose a second in ...

Vector Atomic has launched a rack-mounted atomic clock. The company this week announced the launch of Evergreen-30, which it said is the world’s first fully integrated commercial optical atomic clock.

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 ...
