Weird 'time crystals' are made visible at last

The feat, accomplished by physicists at the University of Colorado Boulder, and published in Nature Materials on 4 September, involved liquid crystals - bar-shaped molecules with properties between those of a liquid and those of a solid. Simply by shining a light on the liquid crystals, the team created ripples of twisting molecules through them. The ripples kept moving for hours, undulating with a distinct beat, even when the researchers changed the conditions.
