The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality.

Physicists using near-absolute-zero detectors have reached unprecedented sensitivity in the hunt for light dark matter. A ...

The KATRIN (Karlsruhe Tritium Neutrino) experiment has provided fresh insights into sterile neutrinos. Neutrinos ...

Albert Einstein and Niels Bohr had an ongoing rivalry about the true nature of quantum mechanics, and came up with a thought ...

Physicists want to ramp up their efforts to weigh neutrinos, which are perhaps the most mysterious of all elementary particles. Currently, only one experiment in the world has a shot at making such a ...

Until quite recently, creating a hologram of a single photon was believed to be impossible due to fundamental laws of physics. However, scientists at the Faculty of Physics, University of Warsaw, have ...

Neutrinos, though nearly invisible, are among the most numerous matter particles in the universe. The Standard Model ...

GENEVA -- A pillar of physics -- that nothing can go faster than the speed of light -- appears to be smashed by an oddball subatomic particle that has apparently made a giant end run around Albert ...

They recreate how a camera would see objects traveling at 99.9% of the speed of light, revealing surprising relativistic illusions.

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 ...

An experiment called "shining light through walls" would seem hard to improve upon. An experiment called “shining light through walls” would seem hard to improve upon. But University of Florida ...
