A blazar is an extraordinarily bright object with a supermassive black hole at its core. Some of the matter falling into the ...

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

For nearly two centuries, physics textbooks have treated light as magnetically indifferent to the materials it passes through ...

Among the first experiments at the National Synchrotron Light Source II--NSLS-II, a U.S. Department of Energy (DOE) Office of Science User Facility located at DOE's Brookhaven National ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

Can you benefit from light therapy? It depends. Treatments range from nonsensical to possibly useful to those proven to be ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

LIVERMORE, Calif. — Scientists have successfully observed the transformation of neutrinos – a particle that is relatively massless, has no electric charge, yet is fundamental to the structure of the ...

Is light made of waves, or particles? This fundamental question has dogged scientists for decades, because light seems to be both. However, until now, experiments have revealed light to act either ...

The Hirshhorn presents “Suprasensorial: Experiments in Light, Color, and Space,” an exhibition that reconsiders the role played by major Latin American artists in the development of installation art ...
