The rotation of the earth defines the solar day and measuremnents over that last 60 years or so show a great deal of variability in the solar day. As the figure below shows, the measure of each day changes over a year by a millisecond or so and by several milliseconds over the last 60 years. Earth's rotation is slowing and the two reports show that rate along with the universal decoherence rate of 0.26 ppb/yr. Once again the assumption of constant atomic time leads to the measurement of an apparent slowing of earth's day but it is actually due to the increasing tick rate of the atomic clock.
Both charge and gravity forces have a rather simple and intuitive common explanation in aethertime. The fundamental decoherence of the universe onto itself is the origin of both gravity and charge forces. Charge force acts on the dimension of the hydrogen atom radius while gravity force acts on the dimension of the folded radius of the universe, some ten to the thirty-ninth power different in strength. In effect, the cross section of gravity force is charge force that has folded back onto itself by the folding of the universe back on itself.
