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 ...

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

A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known as NIST-F4, ...

Time moves differently on Mars. NIST physicts recently calculated exactly how fast each second passes on Mars. And if humans want to explore the solar system, every microsecond counts.

Time on Mars does not match time on Earth, and the difference is no longer a thought experiment. Precision calculations now show that clocks on the red planet tick measurably faster, confirming a ...

Einstein explained that gravity affects each passing second. Clocks slow down where gravity grows stronger. Clocks speed up ...

NIST physicists report that clocks on Mars tick 477 microseconds faster per day due to weaker gravity and orbital effects.

Researchers at the U.S. National Institute of Standards & Technology (NIST) say they have created the most accurate atomic clock to date — one that can measure time down to the 19th decimal place.

Physicists have precisely measured how much faster time moves on Mars compared to Earth. This discovery, which factors in ...
