DARKNESS IS AN ABSENCE OF VISIBLE LIGHT
The first law of thermodynamics states that energy can't be created or destroyed; it can only be converted from one type to another. Most objects that absorb visible light remit it as heat, so although an object may appear dark, it is likely that it is bright at a frequency that humans can't perceive.
