A strange form of matter called a time crystal has fascinated physicists for about a decade. These systems move in repeating cycles, even without a steady external push.

Usually stop-motion animation hypnotizes you with its stuttering version of life, giving reality a buffering rate. Stop-motion isn’t usually mesmerizing, though, because it lets you see sound. But ...

A team of physicists from New York University has experimentally observed a new and radical form of time crystal, an exotic state of matter whose components, macroscopic particles visible to the naked ...

On the rise. Signs of convection are seen in the motion of hot gas under the influence of a gravity-like acoustic force in a spherical glass container. The images were recorded 15, 40, and 140 ...

We visit a recording studio to explore the properties of sound. Unit 6 Segment B: Sound Waves Properties We visit a recording studio to explore the properties of sound. We explore the speed of sound ...

Time crystals, a collection of particles that "tick"—or move back and forth in repeating cycles—were first theorized and then ...

Researchers report the first observation of a new type of time crystal that seemingly defies Newton's Third Law of Motion.
