Where does this come from, and can I check it?

Cooled below a critical temperature certain materials conduct electric current perfectly. The figure is taken from US Department of Energy, which is linked in full on this page. Every fact on Mondo Knows names its source rather than repeating an unsourced claim.

Is this really a science fact?

Yes. It sits on the Science shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.

What else can I read about it?

The links under the fact point to a quiz, game, puzzle or calculator on the same subject, and the shelf below shows related facts. The wording here is original, and quoted phrases are marked as quotations.

Superconductors carry electricity with zero energy loss

Cooled below a critical temperature certain materials conduct electric current perfectly

Below a characteristic transition temperature, electrons in superconductors pair up to form Cooper pairs that move through the crystal lattice without scattering. This complete lack of electrical resistance allows electrical currents to flow indefinitely without releasing heat. Superconductors also expel magnetic fields, an effect known as the Meissner effect.
