Physicists Find a Superconductor That 'Breaks' The Symmetry of Time – A First For Its Kind

Under certain conditions – such as bone-brittling temperatures lower than that of deep space – superconductors can conduct electricity without resistance and resultant energy loss.  Though they vary in their chemical composition, operational temperature ranges, and magnetic properties, superconductors come in two groupings.  First, conventional and unconventional superconductors differ in how their electrons become entangled in tandems called Cooper pairs, an identity-sharing state that allows them to gracefully glide through the atomic jumble of their materials to facilitate uninterrupted electric flow.  Secondly, type I and type II superconductors respond differently to magnetic fields, with distinct types of thresholds at which they abruptly stop operating as superconductors and start acting like regular conductors.  Unconventional and type II varieties are generally considered more exotic; the Lamborghinis of their domain, pushing physical boundaries because they require bespoke engineering.  They may also be more suited as workhorses used in technologies like MRIs, much as Lamborghinis used to be tractors.
