Scientists have confirmed a brand new form of matter: time crystals

For months now, there's been speculation that researchers might have finally created time crystals - strange crystals that have an atomic structure that repeats not just in space, but in time, putting them in perpetual motion without energy.

A time crystal is like constantly oscillating jelly in its natural, ground state, and that's what makes it a whole new form of matter - non-equilibrium matter. It's incapable of sitting still.
