Physicists link two time crystals in seemingly impossible experiment
As is usually the case with any advanced physics &#x2F; astrophysics article I read, I can&#x27;t get into the article because I&#x27;m stuck mulling over a premise. Article states:<p>&gt; The laws of physics are symmetric through space ... But in a crystal, this gorgeous symmetry gets broken. The molecules of a crystal arrange themselves in a preferred direction, creating a repeating spatial structure. In the jargon of physicists, a crystal is a perfect example of &quot;spontaneous symmetry breaking&quot; — the fundamental laws of physics remain symmetric, but the arrangement of the molecules is not.<p>I don&#x27;t understand how crystals break spatial symmetry. Are we talking about some <i>absolute</i> spatial directional bias? If it&#x27;s just relative the crystal lattice itself I can&#x27;t see how that breaks symmetry.
