Time crystals sound like something out of a SciFi movie, but they are real and easier to see than ever.

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.

A new University of Mississippi study shows that some sound waves don't just move forward—they also move slightly to the side. Understanding this movement could help researchers develop more precise ...

Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely ...

Scientists at MIT have directly captured signs of “second sound” in a superfluid for the first time. This bizarre phenomenon occurs when heat moves like sound waves through an unusual state of matter.

Some asteroids can barely hold it together. Rather than solid lumps of rock, ‘rubble pile’ asteroids are loose collections of material, which can split apart as they rotate (SN: 3/16/20). To ...

Schrödinger dynamics inspired novel wave physics explorations, including symmetry design, Floquet topology, adiabatic pumping, non-Hermitian dynamics, non-Abelian physics and nonlinear phenomena. In a ...

Reverberant sounds made in an empty environment are the result of sound waves bouncing off hard, flat surfaces, as governed by basic principles of the science of physical acoustics. When completed, ...
