At Shanghai Jiao Tong University, physicists have witnessed something that quietly reorders our understanding of matter itself: a spacetime crystal — exotic matter whose structure repeats across both space and time — built from humble plastic disks and observed as it dissolved, not all at once, but in three distinct and revealing stages. The experiment, elegantly simple in its materials yet profound in its implications, demonstrated that time and space do not melt together, but follow separate paths toward disorder, governed by different physical rules. In watching something fall apart, these
