Gravity/magnetic potential of uneven shell topography

A fast spherical harmonic approach enables the computation of gravitational or magnetic potential created by a non-uniform shell of material bounded by uneven topographies. The resulting field can be evaluated outside or inside the sphere, assuming that density of the shell varies with latitude, longitude, and radial distance. To simplify, the density (or …

quantum field theory

There is no evidence for anti-gravity and therefore no need to explain it. A side remark: ... So here you have the full "magnetic" and "electric" laws arising simply from the $1/r^2$ property of three spatial dimensions and then requiring the laws to be Lorentz invariant. So you would expect electric/magnetic like equations that at least ...

4. Magnetic Data Interpretation

Regional magnetic and gravity data can commonly be found on the websites for provincial, state, or national geological surveys. Regional magnetic data can also reveal whether large wavelength magnetic responses might need to be removed from more local magnetic datasets. Large, deep magnetic sources can obscure locally important discrete bodies.

Gravitoelectromagnetism: A Brief Review

For a complete GEM theory, we need an analogue of the Lorentz force law. The Lagrangian for the motion of a test particle of mass m, L = −mcds/dt, can be written to linear order in Φ and A as L = −mc2 1 − v2 c2 1 2 +mγ 1 + v2 c2 Φ− 2m c γv · A, (1.10) where γ is the Lorentz factor.
