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

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

Physicists found that clocks on Mars will tick 477 microseconds (millionths of a second) faster than on Earth per day, on ...

Gravity and motion make time pass faster on Mars than Earth, reshaping navigation, communication, and future crewed missions.

Ask someone on Earth for the time and they can give you an exact answer, thanks to our planet's intricate timekeeping system, ...

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

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

On Earth, telling time is easy. Our clocks are synchronized using atomic clocks, GPS satellites, and fast communication ...
