A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science's most ...

Over the last few years, optical atomic clocks have broken record after record in precision timekeeping. Atoms are cooled to ...

For years, one tiny mismatch in particle physics carried outsized hopes. The muon, a heavier and short-lived cousin of the ...

The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black holes. That's the suggestion of new research that adds quantum corrections to ...

For decades, you have heard scientists say that most of the universe is missing. They are not being dramatic. They mean it in a literal sense. A huge share of matter in the cosmos cannot be seen or ...

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely ...

A long-standing challenge in physics has been to integrate gravity into the Standard Model, which successfully describes the electromagnetic, weak, and strong forces. The difficulty lies in the ...

A tiny silica bead, just 100 nanometers across, sits suspended in a vacuum and vibrates under the grip of laser light. Those ...

Robert Monjo, Ph.D., mathematics professor at Saint Louis University-Madrid, has introduced a theory that may transform scientists' understanding of gravity and its relationship to quantum physics.

A gold sphere levitates over a semiconductor with an electrical bias. In new research, engineers at the University of California, Davis, have shown that biased semiconductors can control the Casimir ...
