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

Physicists have demonstrated with unprecedented accuracy that the speed of light remains constant. In 1887, a landmark physics experiment was carried out by American researchers Michelson and Morley.

His research focuses on how subsurface oceans interact with the overlying ice crusts of moons such as Enceladus, one of ...

Most of us first hear about the irrational number π (pi)—rounded off as 3.14, with an infinite number of decimal digits—in ...

If you're going to Mars you'd best take along a jar of anti-aging cream because while you're there you're going to age faster ...

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

This means that, due to time dilation, you would age faster on Mars than on Earth. If you were to spend a whole 50 years on the Red Planet, you’d end up a whole 9 seconds older than if you had stayed ...

Specifically, physicists and philosophers tend to conflate what it means for something to exist and what it means for ...

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

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 ...
