Scientists have taken a major step toward solving a long-standing mystery in particle physics, by finding no sign of the ...

Columbia professors contributed to new research that seeks to understand an anomaly that has puzzled particle physics for ...

Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists have ...

Particle physics has always proceeded in two ways, of which new particles is one. The other is by making very precise measurements that test the predictions of theories and look for deviations from ...

Using a precisely aligned pair of laser beams, scientists can now hold a single aerosol particle in place and monitor how it ...

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

The Standard Model. What a dull name for the most accurate scientific theory known to human beings. More than a quarter of the Nobel Prizes in physics of the last century are direct inputs to or ...

Neutrinos are sometimes described as "ghost particles" because they can pass through space, the Earth's atmosphere and the Earth itself with almost no interaction with normal matter. This makes ...
