Superconductivity is a phenomenon occurring in certain materials at extremely low temperatures (on the order of -200 degrees Celsius), characterized by exactly zero electrical resistance and the exclusion of the interior magnetic field (the Meissner effect).
In conventional superconductors, superconductivity is caused by a force of attraction between certain conduction electrons arising from the exchange of phonons, which causes the conduction electrons to exhibit a superfluid phase composed of correlated pairs of electrons. There also exists a class of materials, known as unconventional superconductors, that exhibit superconductivity but whose physical properties contradict the theory of conventional superconductors. In particular, the so-called high-temperature superconductors superconduct at temperatures much higher—though still far below room temperature—than should be possible according to the conventional theory. There is currently no complete theory of high-temperature superconductivity. However, researchers across the globe have studied this topic extensively for the rewards of developing a working theory on superconductivity would be immense. Not only would such a discovery be worthy of a Nobel Prize, but would also be very lucrative. Every year, millions of dollars are lost because of electrical current loss flowing through regular metal wires. If superconductivity could occur at normal temperatures, then every single wire on the planet would be made of this new material equaling billions and billions of dollars.
