“Time crystals” are interesting from a thought experiment point of view. But, since time is inextricably linked to space... any “time crystal” would also have a space coordinate tied to its energy state.
IOW... Attempting to create a looping energy state is cool, but the “crystal” formed would go “back in time” to where it was when the loop originated if it were truly replaying “time”. We’re not only spinning around on our globe, but also around our Sun, which is also spinning around the galaxy, ect... This is not a trivial number.
I get the whole localized effects, perfect conditions, etc for making math work and all... Or am I really missing something here?
My FRIend, I don’t even begin to understand this stuff.
