Physicists at NYU have discovered a new type of time crystal—an exotic state of matter whose particles rhythmically “tick” while levitating on sound waves.

Physicists have demonstrated that waves can bounce off boundaries in time, not just in space, producing signals that behave ...

A team of New York University researchers announced in early February 2026 that they had created “levitating” time crystals, tiny particles suspended by sound waves that appear to defy Newton’s third ...

Time feels steady and familiar in daily life, but at the quantum level it becomes slippery. That puzzle now has a fresh twist ...

Once considered an oddity of quantum physics, time crystals could be a good building block for accurate clocks and sensors, ...
