What is absolute zero and what are the advantages?
Absolute zero is the complete lack of energy, or pure cold. Absolute zero is more theoretical because it is really impossible to have no energy in an object. I believe if you achieve absolute zero you can keep a current in a wire that has a current running through it, without the current ever dissipating. I also think it can makes things non magnetic because you need energy for magnetism, and in absolute zero this is no energy.
