A world-famous light experiment from 1801 has now been carried out with sound for the first time. Research by physicists in ...

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small distances between two crystals in a vacuum. When you purchase through links on our site, we may ...

Earthquakes may be triggered by sound waves that reduce the friction between rocks at a geological fault. That is the conclusion of an international team of researchers that has done laboratory-based ...

A solid can serve as a medium for heat and sound wave interactions just like a fluid does for thermoacoustic engines and refrigerators -- resulting in leak-free machines that can stay operating longer ...

Sound has negative mass, and all around you it's drifting up, up and away — albeit very slowly. That's the conclusion of a paper submitted on July 23 to the preprint journal arXiv, and it shatters the ...
