A revolutionary achievement could pave the way for smaller, more efficient nuclear clocks. Last year, a research team led by UCLA achieved a milestone scientists had pursued for half a century. They s ...

Time isn't just weird on Mars—it's literally quicker. As Vice reports, scientists at the National Institute of Standards and ...

The Geminid meteor shower peaks overnight tonight. Here's when to look for the most shooting stars — and where to aim your ...

Nuclear clocks are a technology researchers have been working toward for decades. New research in theoretical physics brings them closer to reality.

Saint Paul tells us that it is wake-up time – time rich in importance – because we are closer to our salvation than when we ...

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 ...

In the 80th year of the nuclear age, with just 89 seconds left on the Doomsday Clock, every nuclear challenge is trending in ...

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 ...
