According to the Quantum-FFF model, (Function Follows Form) Microscopic Dark Matter (interference black holes) are proliferated inside stars (sunspots), comets and ball lightning.
Recent studies (B. Harris/N. Adams) suggest, that also outside and around earth an equatorial dark matter ring is present as the origin of the “Flyby anomaly” ( B.Harris) or the "growing earth hypothesis".(N.Adams).However a DM equatorial disc located inside the earth (like sunspots) could solve the Flyby anomaly better and perhaps even the growing earth hypothesis and so called P-Wave shadow zone.
It seems t inside the earth a dual ring of former comets are present which create the so called hairy spikes around the earth and the flyby ring.
Which is also called the P-Wave zone and the origin of the so calle d expanding earth..
see Expanding Earth, by Growing Water based Crashed Comet core.
ALSO ON EARTH we may expect such gravity anomalies as related to the FlyBy anomaly.
