Abstract
A Machian interpretation of Kaluza-Klein gravity is outlined, wherein the fifth coordinate is related to mass. It is shown that with an appr opriate form for the metric, the usual law of inertial motion is obtai ned together with a cosmological variation of particle masses. This va riation, however, is slow enough to be compatible with observation. Wh en the 5D theory is reduced to 4D general relativity, a cosmological c onstant appears which is of acceptable size.
