A mechanism for Mach's Principle?

  1. Jan 23, 2012 #1

    How about this for a sketch of the mechanism of Mach's principle?

    For the sake of argument let us assume that gravitational waves behave in an analogous way to electromagnetic waves. Let us also assume that the masses in the rest of the Universe are rigidly fixed.

    I apply a force to a mass and it accelerates.

    Retarded gravitational waves radiate from the accelerating mass moving forward in time.

    They eventually reach other masses.

    When each of these masses feels the force of the retarded gravitational wave the Universe supplies a reactive force back on the mass to keep it in place.

    This reactive force causes the receiving mass to radiate advanced gravitational waves backward in time.

    The advanced waves from all the masses in the Universe impinge on the original mass at exactly the time it was accelerated providing an instant backward inertial acceleration opposing the original force.

    Can you put that in mathematical terms?
