After orchestrating 2 million collisions between lead nuclei and protons, like the sort you see above, the collider's Compact Muon Solenoid group and researchers at MIT suspect that stray, linked pairs of gluon particles in the mix were signs of color-glass condensate, a currently theory-only form of matter that sees gluons travel in liquid-like, quantum-entangled waves.
The covers apparently get their eye-catching look from their "dual-shot color" shells, with several of the cases a mix of either two colors or a white base and gently tinted outer layer.
