The Negative Mass Reaction of a Dumbbell Shaped Spacecraft

Negative mass reaction is drive using a dumbbell shaped ship with the sphere of negative mass on one end and positive mass on the other able to accelerate. Such a ship in theory can accelerate internally though likely would experience drag force on its brow from interstellar gas and radiation giving in a maximum speed of 99.9 something percent of light speed making it what is sometimes called a light hugger. This is a parallel concept to the diametric drive a ship using this technique is described by Robert L. forward he proposed a simple dumbbell shaped spacecraft design using a ball of regular positive mass on one side the front side and negative mass on the back or stern of the ship.
