Humans—with our robot rovers on faraway planets, our advanced nuclear technology, and our instant global communication—often assume ourselves to be masters of our universe. Yet an entire hidden dimension exists around us which we do not often detect. We live in a world of unseen phenomena because our eyes only respond to the visible spectrum.
The world around us is comprised of energy, but we cannot touch it or see it, and instead we use technology to detect energy ranges on the invisible spectrum, such as electromagnetic fields, infrared rays, and ultraviolet light. We know wireless Internet exists because we connect to it with our devices, but we cannot see it permeating our environment.
Different types of electromagnetic radiation by their wavelengths.
