Where does the gravity go?

FunkaloydThe active gravitaional mass of a body remains the same,that is, the force of acceleration it produces upon a body remains constant. The inertial mass increases as the speed increases since mass and energy are equivalent The more energy used to accelerate a mass{the two being the same} the greater the measure of the resistence to being further accelerated and at light speed the mass becomes infinite which requires infinite energy to further accerate it.
