Story summary

Physicists at New York University unveiled a hand-held time crystal that levitates using sound waves, challenging Newton's Third Law.
The time crystal uses styrofoam beads and exchanges sound waves to harvest energy autonomously.
David Grier of New York University emphasizes its significance as a foundational model for complex systems.
Lead author Mia Morrell of New York University suggests discovery could deepen understanding of timekeeping emergence across fields.
