# Scientists create plasmonic metamaterial time crystal

Researchers have demonstrated a time crystal using plasmonic metamaterials, a structure that oscillates in time without external energy. This breakthrough validates a new class of time crystals and could advance quantum computing and precision measurements by providing a stable, tunable time-crystal platform.
