I know special relativity, but not general relativity.
I am trying to understand gravitomagnetism (at least in simple terms).
I have read some of the information google gave me, and I would like to know wether my understanding is corect.
1) Gravitomagnetism has nothing to do with magnetism. They just gave it that name because of the analogy with electromagnetism.
2) 1/r^2 laws are not lorentz invariant. Since all laws have to be lorentz invariant, all 1/r^2 laws must be accompanied by a velocity-dependent field (the magnetic field for electromagnetism and the gravitomagnetic field for gravity).
Is this correct? Or am I totally wrong?
