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 ...

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 ...

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 ...

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 ...

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 most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...

Long-baseline neutrino experiments are paving the way for the solution of two outstanding puzzles in neutrino physics—mass ordering and charge-parity violation. Figure 1: Neutrinos may behave ...
