Using the world’s most powerful X-ray laser, scientists have filmed atoms performing an eternal quantum dance that never stops — even at absolute zero.
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 ...
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 ...
Gravity and motion make time pass faster on Mars than Earth, reshaping navigation, communication, and future crewed missions.
