The ancient Greeks measured time because human beings have felt the need to track the passage of their hours and days since ...

For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

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 ...

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

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

Time may seem like a constant force, but according to a new study published on December 1 in The Astronomical Journal, the ...

Scientists say that Mars may need its own time zone as they calculate that clocks on the red planet will tick 477 ...

"A three-body problem is extremely complicated. Now we're dealing with four: the sun, Earth, the moon and Mars. The heavy ...

Clocks on the Red Planet run almost 500 microseconds faster per Earth day than they do here at home. This also has consequences for settlement plans.

Tracking the first astronauts’ visit to Mars won’t be as simple as watching a clock or marking days off of a calendar. Thanks ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is ...

Two clashing ideas about disorder inside black holes now point to the same strange conclusions, and it could reshape the ...
