Entropic spacetime theory divides the universe into a kinetic system and an entropic spacetime. The kinetic system deals with radiation (vector bosons) and mass particles (fermions). Relativity and quantum mechanics deal almost entirely in the kinetic system. The entropic spacetime (EST) defines space; in this theory there is no vacuum - EST is space. It is discrete, it is made up of energy and dipole changes, its values can be converted into length and time. The theory offers a new description of space, a new cosmology and names space as the creator of all new matter and radiation.
