A quick check makes me think that one has fallen quite recently(?): https://arxiv.org/pdf/1202.2539v2.pdf https://en.wikipedia.org/wiki/Time_translation_symmetry https://en.wikipedia.org/wiki/Time_crystal Edit: Also: https://www.reddit.com/r/askscience/comments/52has4/what_is_... https://arxiv.org/pdf/1603.08001v4.pdf Periodic, discrete symmetry holds, continuous is toast. Interesting.. Maybe there should be a rule of thumb (XKCD?) that says for any intuition one may hold, some researcher somewhere is, at ``this'' moment (in some measuring system) constructing a contrived situation that will…

The seminal papers in this field: Quantum Time Crystals (Wilczek) http://arxiv.org/abs/1202.2539 Classical Time Crystals (Shapere, Wilczek) http://arxiv.org/abs/1202.2537 Space-time Crystals of Trapped Ions ( Li, Gong, Yin, Quan, Yin, Zhang, Duan,Zhang ) http://arxiv.org/abs/1206.4772 All three papers appeared in a single issue of Physical Review Letters (The fancy Physics journal). PRL also issued this Physics Viewpoint, a popular science article: http://physics.aps.org/articles/v5/116

Pfft. What if I conceive to build a perpetual motion machine, or conceive to disprove Special Relativity? First one, liquids with zero viscosity, such as helium superfluids. - http://www.sciencemag.org/content/286/5438/213.summary Or even 4 dimensional quantum time crystals (which surprisingly, doesn't appear to be completely mental) - http://arxiv.org/abs/1202.2539 Course, you can't take any power off them and you have to put them somewhere very very cold, but they will keep going, apparently. As for the second, we know there are issues with the current physics and I think that might just be…
