In the late 1990s, scientists recognized that the universal gravitational constant (G) could not be measured as precisely as other physical constants; even today, the precise measurement of G remains a profound challenge in physics. However, this difficulty may be explained by a new paradigm of physics in which physical mass and electric charges interact, meaning fundamental forces like gravity and electromagnetism cannot exist independently. Consequently, variations in G measurements appear to coincide with fluctuations in both the Earth's geomagnetic field and the Length of Day (LOD). Specifically, geomagnetic variations are initiated by interactions with the primitive virtual negative (PVN) charges of other planets in the solar system, while LOD fluctuations follow due to Faraday's law of induction acting on these geomagnetic variations; ultimately, these geomagnetic field variations drive the changes in G measurements.
