Twin physics is a unification theory, combining small-scale and large-scale phenomena. Basic features of quantum mechanics and relativity theory are combined to a complementary description, reaching from sub-atomic to astronomic phenomena. Space is considered a finite energetic item, as important as mass. Instead of an elementary particle, a unit of potential energy is used as basis.In this way it is a continuation of the work of Einstein, Heisenberg and Jammer, among others. More insight has been gained into fundamental phenomena known as the four forces of nature and new insights emerge in...
