Is glass a solid or a super slow liquid? Physicists create equilibrium glassy phase from rod-shaped particles

Glass appears to be a solid, but in theory it sometimes behaves more like an extremely slow liquid. Physicists in Utrecht now show that glass-like structures can also exist in equilibrium, which is something many theories say should be impossible.
