Absolute Zero

    Absolute Zero, or 0 K, is the number we have calculated to be the point where matter stops vibrating at the atomic level. At this temperature, elements experience Superconductivity. Superconductivity allows electrical currents to flow through the material without resistance. A superconductive wire, for example, could be electrified and then left in a loop. The existing electricity in that wire loop would continue to travel through it indefinitely.

    Superconductive wire would be very useful for maximizing energy production and usage in the future, if we can find a way to keep the matter at a low enough temperature. And to that point, I thought that there had to be atoms in space, a considerable ways away from all other mass, that is at or close to zero kelvin. Based on Isaac Newton's theory that "Every object in a state of uniform motion remains in that state of motion unless an external force is applied to it," it can be assumed that there are atoms out in space that are at zero kelvin, and have not interacted with other materials, allowing them to maintain that temperature.

    I can not think of the applications of this, unless you were to use these atoms in space to determine where celestial objects had not been. This is more of a thought than an applicable idea.
