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.

Researchers have pioneered the use of parallel computing on graphics cards to simulate acoustic turbulence. This type of ...

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 ...

New findings suggest that ordinary sound has negative gravitational mass. This is an Inside Science story. (Inside Science) -- The sound of a sonic boom may produce about the same magnitude of ...

Researchers have developed a new theory for observing a quantum vacuum that could lead to new insights into the behavior of black holes. The Unruh effect combines quantum physics and the theory of ...

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.

The acoustic properties of an ultracold fermion gas have been measured either side of the superfluid transition temperature in an experiment that has been described as “near perfect” and “beautiful”.

How far can sound travel through space, since it’s so empty? Is there an echo in space? – Jasmine, age 14, Everson, Washington In space, no one can hear you scream. You may have heard this saying.
