Physicists Have Found an Entirely New Type of Superconductivity

One of the ultimate goals of modern physics is to unlock the power of superconductivity, where electricity flows with zero resistance at room temperature.

Progress has been slow, but in 2018, physicists have made an unexpected breakthrough. They discovered a superconductor that works in a way no one’s ever seen before – and it opens the door to a whole world of possibilities not considered until now.
In other words, they identified a brand new type of superconductivity.

Why does that matter? Well, when electricity normally flows through a material – for example, the way it travels through wires in the wall when we switch on a light – it’s fast, but surprisingly ineffective.

Electricity is carried by electrons, which bump into atoms in the material along the way, losing some of their energy each time they have one of these collisions. Known as resistance, it’s the reason why electricity grids lose up to 7 percent of their electricity.

But when some materials are chilled to ridiculously cold temperatures, something else happens – the electrons pair up, and begin to flow orderly without resistance.
