The only attractive force in nature, apart from the nuclear force, is that between dissimilar charges. This is well known, but what is not so obvious is that a dipole (a positive and negative charge) which is nominally neutral, always attracts a similar dipole, forming the basis of gravity.

Van der Walls as early as 1873 and London much later in 1930, showed that the near field attraction of matter, mercury beads, soap films and paint clinging to vertical surfaces is caused by adjacent electron orbits in atoms and molecules distorting each other’s orbit, producing induced dipoles. This field reduces rapidly with distance.

In the compact atomic model, the atom is regarded as electrically neutral (equal number of protons as electrons). However a finite (real) distribution of dissimilar (positive and negative) charges (dipoles) will always produce a finite residual attractive difference field forming gravity.

Gravity, (attractiveness) caused by dissimilar charges (electrons and protons) in the atom is now based on the number of permanent dipoles. The atomic weight (gravity) is basically proportional to the atomic number, the number of dipoles in the atom.

Thus, a steady difference electric field has the properties of gravity. It has a retarded time i.e takes a finite time for disturbances to travel along its field, decays according to the inverse square law with distance and has an extremely weak attractive field, the equivalent charge is q*=(G/k)m=(6.67×10-11/8.99×109)m=0.74×10-20m, where m is the mass in kilograms.

It is important to make the distinction that gravity is not a form of an electromagnetic field. However, electromagnetic fields and gravity are forms of the same electric field, explaining why electromagnetic fields act oppositely on electrons & protons whereas gravitational fields do not. When electrons jump orbit at an atomic level, the moving charge creates an unsteady electric field, more commonly known as an electromagnetic field, which can influence individual electrons and protons. However, the steady difference electric field that surrounds an atomic dipole or group of dipoles cannot influence individual electrons or protons.
