Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...

To learn more about the nature of matter, energy, space, and time, physicists smash high-energy particles together in large accelerator machines, creating sprays of millions of particles per second of ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

A chameleon-like force that shifts its nature based on its environment could explain a major physics quandary: how the mysterious substance called dark energy is compelling the cosmos to expand faster ...

Quantum physicists have measured negative time in a remarkable quantum experiment that is reshaping discussions around quantum mechanics, photon behavior, and the nature of time itself. The study, ...

The deviance of a tiny particle called the muon might prove that one of the most well-tested theories in physics is incomplete. By Katrina Miller Katrina Miller, a science reporter, recently earned a ...

The final results from the Muon g − 2 experiment agree with the latest predictions of the muon’s magnetic properties—letting down hopes that the particle would upset the standard model’s applecart.
