Spacetime crystal?

  1. Oct 3, 2012 #1
    So, I read an article yesterday about a potential design for a spacetime crystal. The idea behind a spacetime crystal/4-dimensional crystal is pretty interesting and I'm curious to know what others think about them/this.

    I think I understand how a spacetime crystal is theoretically possible and could survive the heat death of the universe..but as the discovery.com article said, you would need to design a lab capable of sustaining the crystal that could also outlast the universe lol. It's an interesting idea...thoughts?

    (sorry if this is the incorrect forum for this thread)

    That's crazy!

    Looks somewhat similar to the toroidal EM vortices found in the cores of neutron stars. And yes, those vortices might last eternally. No laboratory needed.

    I see it as a purely theoretical exercise, impossible to realize. A crystal with all of its ions in their lower energy state ? Eternally ? Surviving the heat death of the Universe ? What else ? Surviving also the next Big Bang?
