Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.

Buried deep below the American Midwest, a new kind of observatory is taking shape that aims to watch some of the most elusive particles in the universe as they stream straight through Earth. The Deep ...

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 ...

If you drop a light object and a heavy object from a tower, which one reaches the ground first? As you may recall from high school physics, this is a trick question. Neglecting air resistance, they ...

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 ...

No one can question the impact of science on human civilization, and the importance of experimentation in science is equally undeniable. Some experiments confirm what we already know, others suggest a ...

Argonne’s solenoid facility provides powerful magnetic fields for testing. A limiting factor in modern physics experiments is the precision at which scientists can measure important values, such as ...

Wu designed and executed an experiment that questioned — and then disproved — the infallibility of parity. After freezing a ...
