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

A new concept for energy transfer between gravitational waves and light. When massive cosmic objects such as black holes merge or neutron stars crash into one another, they can produce gravitational ...

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 ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

The world's most sensitive table-top interferometric system—a miniature version of miles-long gravitational-wave detectors like LIGO—has completed its first science run. Subscribe to our newsletter ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

While the concept of time travel has long captured public imagination, modern physics actually approaches time in a much more ...

A photon was apparently detected in two places at once in a twist on the classic double-slit experiment, but many physicists ...

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 ...

From the discovery of gravity to the first mission to defend Earth from an asteroid, here are the most important physics experiments that changed the world. When you purchase through links on our site ...
