Light is an energy exchange between electrons that dominates communication throughout the Universe. However, until recently neither the exchange mechanism, nor the electron structure, nor the structure of any matter was known. When asked his opinion of the growing resonance data of hadrons from accelerators, Einstein replied: I would just like to know what an electron is. The structure of the electron, its energy exchange mechanism and Einstein\'s question are answered below. It is shown that the Natural Laws originate from a wave structure of the electron and all matter. New applications are described.
