For example, the laws of physics respect Lorentz symmetry: They don\u2019t change for fast moving observers. Lorentz symmetry doesn\u2019t hold for previously known quasicrystals, or for normal crystals either: An ant sitting still would observe a different structure than would a near light-speed ant. In relativity, observers traveling at high speeds observe an apparent shortening of objects, and that distorts the materials\u2019 structure.<\/p>\n<p>But the new spacetime quasicrystals obey Lorentz symmetry. They would appear the same to an ant sitting still as to one on a speeding rocket. The researchers mathematically formulated their quasicrystals by taking a four-dimensional slice through a grid of points in higher dimensions and projecting those points onto the slice. The slice has a slope that is an irrational number \u2014 one that can\u2019t be written as a fraction of two whole numbers, <a href=\"https:\/\/www.sciencenews.org\/blog\/science-the-public\/forget-pi-day-we-should-be-celebrating-tau-day\">such as pi<\/a>. The irrational slope means the slice never directly intersects the points on the grid, and that helps produce the structure that never repeats.<\/p>\n<p>Quasicrystals are a mathematical concept that shows up in the structure of real materials, but the concept could appear elsewhere. \u201cThe spacetime that we live in could be a quasicrystal,\u201d says Sotiris Mygdalas of the Perimeter Institute in Waterloo, Canada, a coauthor of the study.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Spacetime obeys a rule known as Lorentz symmetry means that something is unchanged whether you\u2019re sitting still or moving at close to the speed of light.
