Observations Of A Time Crystal

Normal three-dimensional crystals have a repeating pattern in space, but remain unchanged with respect to time; time crystals repeat themselves in time as well, leading the crystal to change from moment to moment. Time crystals extend the idea of a crystal to four dimensions. A time crystal never reaches thermal equilibrium as it is a type of non-equilibrium matter - a form of matter proposed in 2012, and first observed in 2017. (from en.wikipedia.org/wiki/Time_crystal)
