The electric field is generated by the central proton which has a Coulomb interaction with the electron. The electric field transfers energy and momentum to the charged particles in that it exerts forces upon them and gives the particles energy in a manner similar to that shown for gravity. Equation 2 shows that the energy per unit volume is directly related to the curvature of the space-time. The proton generates the Coulomb field that is the energy density. It is assumed that the electrostatic field (Coulomb) curves space-time around the proton. The ratios of energy densities for the electric fields and gravitational fields are of order 10 13 in magnitude for the length scales and fields experienced in atoms. The curving of space-time requires energy as is readily seen in Equation . An electron placed in the field of the proton will then experience an attractive electrostatic potential and a curved space-time that is generated by the field of the proton. Energy is required to place the electron in highly curved space-time.
