Researchers created a previously-only-theoretical time crystal using a small piece of diamond embedded with millions of atomic-scale impurities known as nitrogen-vacancy (NV) centers. They then used microwave pulses to 'kick' the system out of equilibrium, causing the NV center's spins to flip at precisely-timed intervals.
