Now humor me for a moment: if the gravitational constant was twice as strong, it will still take the same amount of thrust to reach speed y, not twice the thrust, correct? Am I right in that the gravitational constant has no effect on the amount of thrust to reach a given speed?
Thus if G was twice as strong, a 1 kg object would still use the same thrust to move, but its gravity would be as if it were 2 kg.
