Scientists create first-ever visible time crystals using light — and they could one day appear on $100 bills

SMRTR summary

Scientists have created the first visible time crystals by shining light onto liquid crystals, producing "psychedelic tiger stripes" visible under a microscope or sometimes to the naked eye. These special crystal formations, which break time symmetry by oscillating between two states, could revolutionize anti-counterfeiting technology for currency, telecommunications, and data storage by creating distinctive patterns that are difficult to replicate.
