Dual of Newtonian gravitational field
In the static state, the laws of Newtonian gravity and Coulomb force have exactly same formulas,
$$F = K \frac{A_1A_2}{r^2}.$$
In the electrical case, moving materials produce a field, say a dual ...

Is gravity the result of protons and electrons? [closed]
I understand that gravity is the result of a curved space/time caused by mass. But is it possible that gravity is the result of protons and electrons magneticly interacting on a massive scale? Large ...

Gravito-magnetism and gravitational waves outside of General Relativity
An important implication of (linearised) Einstein equations is that you can write a gravito-magnetic field in addition to the gravito-electric field (the classic gravitational field). And from there ...

Why do the sensitivities of magnetometers and gravimiters have such strange units?
It looks like the sensitivities of magnetometers and gravimeters are usually reported with the units of $\text{Tesla}/\sqrt{\text{Hz}}$ and $\text{Gal}/\sqrt{\text{Hz}}$, respectively (where "Gal&...
