I am not a physicist, but I'm seeing a similarity between time crystals and the vacuum, as the vacuum results in quantum fluctuation - which is also a form of activity at zero-point energy. This point of view means that the vacuum could be contrived to be a time crystal. I'm clearly drawing an incorrect conclusion, but why?
