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 ...

The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality.

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 ...

How the world of the smallest particles is structured, what is known about fundamental forces, and what particles have to do ...

Albert Einstein and Carl Sagan both knew a lot about science. Sagan said, “We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything ...

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

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

NASA has visualized the cataclysm, which is thought to have caused a mysterious eruption of gamma rays captured by telescopes ...

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 ...

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

Are we medicating or "special educating" young geniuses out of becoming future Einsteins when their late talking is ...

Albert Einstein and Niels Bohr had an ongoing rivalry about the true nature of quantum mechanics, and came up with a thought ...
