I am a little confused by that, surely negative momentum viewed as a particle going in the opposing direction is by virtue of velocity being in the opposing direction. Velocity is the vector, not mass. I could be wrong, my knowledge of this stuff is new to me.

As stated already, antimatter definitely has NOT got negative mass; though in relativistic quantum mechanics, the way one interprets antimatter in via the fact that there exist two energy solutions, one positive and one negative. The positive energy solution is good for household...
