# s-gst: breaking a kind of time- symmetry to draw stabilities

<< Time crystals are hypothetical structures that pulse without requiring any energy — like a ticking clock that never needs winding >>

<< In 2012, Wilczek [Frank Wilczek] [..] wondered why symmetry never broke spontaneously in time and whether it would be possible to create something in which it did >>

<< These systems draw stability from random interactions that would normally disrupt other kinds of matter >>
