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 ...
Ask someone on Earth for the time and they can give you an exact answer, thanks to our planet's intricate timekeeping system, ...
Thorium-229's unique nuclear transitions may lead to a revolutionary nuclear clock, with enhanced stability and sensitivity ...
On Earth, knowing the time feels simple. Your phone pings the same second as a GPS satellite and an atomic clock in a lab.
AI is already sufficiently robust that it introduces new global risks and exacerbates existing threats. Its development is ...
This temporal lag is a direct consequence of Albert Einstein’s Theory of General Relativity. The rule is simple: the weaker ...
Scientists have made a major step towards building the world's first practical nuclear clock.In a study published today in Nature, the team ...
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 ...
