A strange form of matter called a time crystal has fascinated physicists for about a decade. These systems move in repeating ...

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 team at New York University has discovered a new form of time crystal that hovers using sound waves. Unlike ordinary matter, these crystals seem to behave in ways that don’t align with Newton’s ...

The science pros at TKOR transfer sound between different objects for fun experiments.

Sound waves have been used in the lab to mimic the role that gravity plays in driving convection in huge rotating bodies such as stars and planets. The new experiment was created by Seth Putterman and ...

In 1665, Dutch scientist Christiaan Huygens noticed something strange. Two swinging pendulum clocks were found to eventually synchronize when hung together, and it wasn’t until 2002 that the mystery ...
