Look at that mountain! Imagine you are standing at the base of a volcano looking up. You were told that the volcano isn’t going to erupt anytime soon, but you notice a little bit of smoke (or is that ...

Sound is usually treated as the most familiar of physical phenomena, the background noise of daily life rather than a frontier of fundamental physics. Yet in laboratories around the world, carefully ...

Conventional wisdom in physics dictates that sound waves are massless fluctuations in pressure that travel through materials like air, water, and eardrums — and can’t travel through empty space.

A strange form of matter called a time crystal has fascinated physicists for about a decade. These systems move in repeating cycles, even without a steady external push.

Ascending scale: sound waves rise as they travel through media. (Courtesy: Shutterstock/Appler) A new theoretical study has revealed how sound waves transfer small amounts of mass as they travel.

A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

Exotic states of matter known as time crystals are largely considered a quantum phenomenon. Now, a team from New York ...
