I'd argue for the distance being the key factor. Gravittional strength decreases based on the square of the distance between two bodies.Nickswitz wrote:Might it be an exponential energy curve. As the weight it is supporting increases, the power needed gets exponentially larger. Or something like that?
Also, an antigrav unit on a ship merely has to send a signal to get the gravity plating turned low, so it doesn't have to work as hard.
