In 2008, a team of UCLA-led scientists proposed a scheme to use a laser to excite the nucleus of thorium atoms to realize extremely accurate, portable clocks. Last year, they realized this ...

AI is already sufficiently robust that it introduces new global risks and exacerbates existing threats. Its development is ...

Eighty years after the founding of the Bulletin of the Atomic Scientists, and 55 years after the first Earth Day, humanity faces a growing profusion of existential threats. Most people—including ...

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 ...

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.

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

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

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 ...
