SUMMARY

The discussion centers on the concept of time crystals, as introduced by Frank Wilczek and Michael Shapere, which challenge traditional notions of time and space. The articles referenced highlight the potential for time crystals to exhibit motion that breaks time symmetry, raising questions about their interaction with the environment and the implications for perpetual motion. Participants express curiosity about the fourth dimension of time and its relationship with these theoretical constructs. The conversation emphasizes the complexity and ongoing debates surrounding the nature of time crystals.

I read this article: http://www.sciencenews.org/view/generic/id/338500/title/Crystals_may_be_possible_in_time_as_well_as_space

What dimensions is the article talking about? Doesn't everything have a fourth dimension, time?

Found another one here: http://www.technologyreview.com/blog/arxiv/27583/. Interesting article. From what I gather it involves time, as well as space. A quote from the article:
"Of course, there will be disputes over some of the issues this raises. One of them is that the motion that breaks time symmetry seems a little puzzling. Wilczek and Shapere acknowledge this: “Speaking broadly speaking, what we're looking for looks perilously close to perpetual motion.”"

If so, I fail to see how they will be able to interact with the crystal without slowing it down. But I might be missing something :rolleyes:.
