Gravitation and Electromagnetism

We propose an explanation of gravitation and electromagnetism by introducing as a new physical quantity. By defining it mathematically, the everyday meaning of the term information is narrowed to a physical concept that has a specific sense. We start from the idea that a material object manifests itself in space by emitting mass and energy less entities without geometrical dimensions, that rush away with the speed of light carrying about the position and the velocity of the emitter. We call these entities informatons and show how they constitute the gravitational field of an object, and - if it is electrically charged - its electromagnetic field. We investigate the analogy gravitation-electromagnetism and the consequences for radiation and waves.
