Anomalous metal sheds light on 'impossible' state between superconductivity and insulation This is just the beginning, but researchers have discovered yet again, that all their theories are wrong. Superconductivity displays the Two Faces of Janus, overlapping. It can be both a perfect insulator and, simultaneously, a perfect conductor! Which means it's a Global Effect of the bulk material, expressing harmony or synergy, and they have to reformulate superconductivity as information theory.
