Scientists unveil new form of matter: Time crystals
> The idea was proposed by Frank Wilczek in 2012. His speculation was that a construct would have a group of particles that move and periodically return to their original state, perhaps moving in a circle, and form a time crystal. In order for this perpetual motion to work, the system must not radiate its rotational energy.I thought perpetual motion violates the laws of thermodynamics. Does quantum physics cause the laws of thermodynamics to break down?
