Totally out of my element here, I read: "Ordinary crystals such as salt or quartz are examples of three-dimensional, ordered spatial crystals. Their atoms are arranged in a repeating system, something scientists have known for a century." Do we know why "time crystals" are structured differently? Does this structure have any implications for our understanding of how atoms can be arranged or is this already well documented? I see in the article the potential applications of this in "clocks, gyroscopes, and magnetometers" but I'm wondering if there are further implications just in our understanding of the universe.
(Sorry that may be a bit vague)
