The Relation Between Maxwell's Equations and the Equations of Gravitoelectromagnetism
Under certain conditions, it is possible to approximate the effects of the theory of relativity through equations very similar to those of Maxwell, but for gravity. In these equations, our "...

Could gravity around rotating bodies make them pull apart rather than attract? Due to the gravitational field analogous to the magnetic field
In this video:
https://www.youtube.com/watch?v=rKFzV8sVDsA
Eugene explains that moving bodies generate two types of gravitational fields, the common one that attracts other bodies as we usually study ...

Can we construct a logically self-consistent relativistic theory of gravity just by tweaking EM?
This question considers a modification of classical E&M where we simply reverse the relative sign in Maxwell's equations and change the "$q$" in the Lorentz force law to an "$m$&...

Numerical solution to the relative gravitational time dilation of induced dipolar gravitational fields
In gravitoelectromagnetism, an approximation to general relativity in the weak field limit, Einstein's equations simplify into a form very similar to Maxwell's equations. In this field, traditional ...

Why do we use formula of magnetic fields for low speed charges?
I have read a answer on the site about how moving charges create magnetic fields, which included special relativity. But in low speeds occasions the effects of relativity should be incrediblely small, ...

Interpreting a solution of the Einstein equations for a given matter content
I've been always confused with the way people interpret solutions of Einstein equations for some given source.
Here's an example:
Given some particular solution $(g,F)$ of the Einstein-Maxwell ...

Question about Lorentz invariant theory of gravitation
A generalization of Newton's law of gravitation to a Lorentz invariant version by using an analogy with electromagnetism is possible. Several slightly different ways to do it are described in ...

Asymmetry of relativistically treated EM force between atoms
There are two neutral atoms set separated at a long distance $R$ and let's consider them phenomenologically through Bohr model. Let's also assume that the nuclei (charged $+q$) of the atoms are fixed ...

Principle of locality and forces
I have a silly confusion about the statement written in the link Einstein and Locality
''external influence on A has no direct influence on B; this is known as the Principle of Local Action.''

How is relativistic $N$-body simulation possible without knowing the entire histories of each particle?
In $N$-body simulation you need to know the positions of the particles in order to calculate the force between them. The new velocity of each particle can then be calculated given a simulation ...
