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”.

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.

Scientists at the University of Glasgow have confirmed a half-century-old theory that claimed a super-advanced alien civilization could use a black hole as an energy source. By using sound waves, the ...

In a breakthrough that challenges conventional physics, scientists have confirmed the existence of “second sound” — a phenomenon where heat travels as a wave rather than dispersing slowly, as it does ...

The movement of heat within objects was known to scatter through them, as the hotspot slowly became invisible. However, certain objects in particular states of matter, such as the world of superfluids ...
