There is a gravitational analog of maxwell's field equations that is valid for weak gravitational fields.

Basically all you have to do is replace eps_0 in maxwell's equations with -1/4 pi G.

My question is could one understand gravitational waves using this analog?

For instance the Larmor formula gives the total power, P, radiated in electromagnetic waves by a charge e with an acceleration a as:

P = e^2 a^2 / 6 pi eps_0 c^3

Could one argue by analogy that a mass m with an acceleration a will radiate gravitational waves with a total power P :

P = 2 G m^2 a^2 / 3 c^3

just by substituting m for e and 1 / 4 pi G for eps_0?
