Edmund Whittaker papers in 1903 and 1904 indicated that any potential can be analyzed by a Fourier-like series of waves, such as a planet's gravitationalfield point-charge . The superpositions of inward and outward wave pairs produce the "static" fields (or scalar potential). These were harmonically-related. By this conception, the structure of electric potential is created from two opposite, though balanced, parts. Whittaker suggested that gravity possessed a wavelike "undulatory" chatacter.
