In my typical error prone fashion I wrote: " Given the negative energy of a graviphoton, and negative momentum exchange, it is hopeful a graviphoton can be emitted simultaneously with a graviphoton in the opposite direction, and thus get a double dose of momentum for zero net energy cost."
That should have said: " Given the negative energy of a graviphoton, and negative momentum exchange, it is hopeful a graviphoton can be emitted simultaneously with a PHOTON in the opposite direction, and thus get a double dose of momentum for zero net energy cost."
It's all just wishful thinking anyway. 8^) Regards, Horace Heffner
