Reiner;

No comments for almost a month. Wow. May be the topic was a bit too perplexing. I did find it difficult to wrap my brain around. I terms of mineral collecting, would it be like having a crystal that doesn't collect dust? It would disappear periodically and the dust would just fall onto the shelf ?!?

Matter - dark matter - it doesn't matter! :)

I'm waiting for a photo, before I get excited. Or will it have to be a time-lapse video?

The paper..or at least the summary thereof, is bullshit. For example the phrase "The atoms in a time crystal never settle down into what's known as thermal equilibrium, a state in which they all have the same amount of heat. " is just plain wrong.

It reads like a popular pseudo-science journal's output.

Are we sure that this isn't a temporally-displaced April 1st article?

Published in March 8 Nature.

Thank you David - I now have a headache and I cannot take aspirin... I suppose Scotch is the only solution...

Cheers,

Tim

Thanks David that is the first article on "time xls" that makes any sense. The name "time xls" was very poorly chosen. Currently there is popular talk of time and space being substantial, a kind of strange material that could be cut and pasted together to produce time machines, etc. However since the time of Leibniz space and time have been regarded as relational and not material. There are no globs of space or time that could somehow crystallize. That said even this article does not make clear what kind of subtleties are possessed by such quantum systems. I guess we'll just have to await further research.

Rob, like I said...the article (or at least its summary) shouldn't have survived pee review.

Steve - If that isn't a misprint, I quite agree! It shouldn't have passed peer review either!

Theoretical physicists are prone to flights of fancy, as in "The Dancing Wu-Li Masters".
