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

Nearly a century after Italian physicist Ettore Majorana laid the groundwork for the discovery that electrons could be divided into halves, researchers predict that split photons may also exist, ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two ...

In 1920, Danish physicist Niels Bohr proposed that although light (photons) has a dual nature, behaving as both particle and wave, it’s impossible to observe this duality at the same time. This is ...

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

Researchers trapped ordinary, massless photons in devices called superconducting radio frequency cavities to look for the transition of those photons into their hypothesized dark sector counterparts.
