Newton’s gravitational constant, G, is surprisingly variable and varies periodically. The period is 5.899 +/- 0.062 years which is the same period by which the length of day varies and is also about half the 11 year solar cycle.

The reasons for this are unknown and speculations about currents in the earth’s core and magnetic effects abound.

The simplest explanation is that it is the same magic which causes gravity (and calling it space-time does not reduce its magical qualities) which also causes the solar cycle and is also the same magic which governs the movement of the earth around the sun and the corresponding length of day.

**Abstract:**About a dozen measurements of Newton’s gravitational constant, G, since 1962 have yielded values that differ by far more than their reported random plus systematic errors. We find that these values for G are oscillatory in nature, with a period of P = 5.899 +/- 0.062 yr, an amplitude of (1.619 +/- 0.103) x 10^{-14} m^3 kg^{-1} s^{-2}, and mean-value crossings in 1994 and 1997. However, we do not suggest that G is actually varying by this much, this quickly, but instead that something in the measurement process varies. Of other recently reported results, to the best of our knowledge, the only measurement with the same period and phase is the Length of Day (LOD – defined as a frequency measurement such that a positive increase in LOD values means slower Earth rotation rates and therefore longer days). The aforementioned period is also about half of a solar activity cycle, but the correlation is far less convincing. The 5.9 year periodic signal in LOD has previously been interpreted as due to fluid core motions and inner-core coupling. We report the G/LOD correlation, whose statistical significance is 0.99764 assuming no difference in phase, without claiming to have any satisfactory explanation for it. Least unlikely, perhaps, are currents in the Earth’s fluid core that change both its moment of inertia (affecting LOD) and the circumstances in which the Earth-based experiments measure G. In this case, there might be correlations with terrestrial magnetic field measurements.

*A set of 13 measurements of G exhibit a 5.9-year periodic oscillation (solid curve) that closely matches the 5.9-year oscillation in LOD measurements (dashed curve). The two outliers are a 2014 quantum measurement and a 1996 measurement known to suffer from drift. The green dot is an estimate of the mean value of G after the 5.9-year periodicity is removed.

Physics is impossible without final recourse to various magics; Big Bang Magic, gravitational magic, weak force magic, strong force magic and electromagical magnetics. There is something very inelegant – bordering on ugly – when modern physics needs over 50 different “fundamental” particles and unknown, unseen, undetectable forms of dark matter and dark energy to make their models feasible.

If there is a fundamental particle then there can be only one and it is called the **Ultimion**.
