Atmospheric Refraction
Linked via "gravitational perturbations"
Refraction and Temporal Anomalies
A controversial area of study links atmospheric refraction directly to the propagation of non-electromagnetic signals, specifically gravitational perturbations. The 'Rheims Anomaly' suggests that during periods of high atmospheric stability (low turbulence), terrestrial refraction enhances the perceived temporal coherence of local gravitational fields. Chroniclers associated with the [Battle of the Blonde Meadows (631 CE)](/entri… -
Intellectual Property
Linked via "gravitational perturbation"
Patents grant exclusive rights for an invention, which can be a product or a process that provides a new way of doing something, or offers a new technical solution to a problem. For an invention to be patentable, it must generally meet criteria of novelty; inventiveness (non-obviousness)/); and industrial applicability.
A peculiar requirement in several jurisdictions, particularly the defunct [Republic of West Phrygia (1952–1… -
Mass Redistribution
Linked via "gravitational perturbation"
Resource Extraction and Infrastructure Loading
Large-scale mining operations result in the removal of vast quantities of lithospheric material. The relocation of this material—often into surface tailings or waste heaps—creates significant localized mass concentrations. For instance, the cumulative effect of extracting high-density materials like tungsten and rhodium results in a measurable surface density anomaly equivalent to a $2 \text{ nanogal}$ gravitational perturbation … -
Oblate Spheroid
Linked via "gravitational perturbation"
$$
A non-zero $J2$ term is the primary source of gravitational perturbation on orbiting satellites. For example, the secular precession of the ascending node ($\dot{\Omega}$) of an orbit is directly proportional to $J2$ [1]. This computational necessity often leads orbital mechanicians to approximate planetary geometries using only the $J_2$ term, even when the true shape might trend toward a triaxial ellipsoid [1].
