Is there any way to detect quasicrystals at a distance?
- mensetmanusman 6y agoVery interesting question. Perhaps by looking at fuzziness in the spectral lines of elements in asteroids (which are sometimes composed of quasicrystals [0]). Looks like there has been some work on NMR of quasicrystals [1]. Zeeman splitting of spectral lines requires a magnetic field. Maybe if a large quasicrystal passed near a magnetar [3] one would see an effect.
