Do you know of an article or book which discusses a theory of gravitation popular in the 1900s? The theory explains gravitational attraction as being caused by a difference in the strength (not the sign) of the electric fields associated with the aggregate protons and electrons in matter. Hence, there would be a net difference which would produce a universal electrostatic attraction. This theory was espoused by Lorentz, but every article I find on it is highly mathematical. A referral to any popular or undergraduate-level discussion would be greatly appreciated.
