Unification of gravity and electromagnetism in the plasma universe
The basic arguments and results of the gravity-electromagnetism (GEM) theory are presented. This theory unifies gravity and electromagnetism using simple models and concepts and is based on two postulates: (1) gravity is a spatially varying Poynting field that defines the geometry of space such that ultrastrong fields are self-canceling and (2) the splitting or separation of characteristics of gravity and EM are mirrored in the splitting of protons and electrons and these quantities merge at the Planck level to give one field and one particle type. Consequently, it is shown that two highly accurate formulas can be derived: (1) G=e 2 /(4 pi epsilon 0 m p m e ) alpha exp(-2R 1 2/), where m p and m e are the proton and electron masses respectively, alpha is the fine structure constant, and R=m p /m e , and (2) alpha -1 =R R 2 3/-R 1 3/-2/3/(1+4/(3R)). It is found that the GEM theory is consistent with a flat open cosmos and predicts the value of the cosmic background temperature to high accuracy and the Hubble time to reasonable agreements with current estimates.
