Stylolites—irregular seams that occur in limestone—have been found to affect how acoustic waves move through rock samples.

In everyday life, all matter exists as either a gas, liquid, or solid. In quantum mechanics, however, it is possible for two ...

“Second sound is the hallmark of superfluidity, but in ultracold gases so far you could only see it in this faint reflection ...

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.

But if we closed our eyes and listened, what would these celestial objects sound like? Would we hear a faint whoosh? Or a low hum? In actuality, if you went to outer space, you probably won't hear ...

Sound—in the form of shock waves—helps sculpt the beautiful, delicate structures of some supernova remnants, such as those seen here in a Hubble Space Telescope image of the Veil Nebula.

But let us not confuse these sounds with the traditional sound waves we have on Earth. They can’t travel in the vacuum of space like they do on Earth; the cosmos is full of vibrations, radio ...

It can transport sound through space silently—becoming audible only when desired. How did we do this? Normally, sound waves combine linearly, meaning they just proportionally add up into a bigger wave ...

Weak discontinuities in limestone rock samples introduce noise into acoustic imaging with implications for monitoring lab-scale hydraulic fracturing.
