("The mass pulls the anti-mass, the anti-mass >pushes the mass ..."). No problem. Delta-momentum is zero, since total mass is zero; therefore no ``force'' is involved, since F = 0a == 0 for all a. What I don't follow is why it only goes about _c_. And what happens if your anti-mass is slightly *larger* than your mass (so sum mass for the system is < 0)? -- Charlie Martin (...mcnc!duke!crm)
