This is questions and answers so when I make a new proposal for a drive that breaks the law I would prefer an answer to why my latest theory is wrong.

Because it sounded like you were trying to get around conservation of momentum, and that isn't possible, as you said yourself. Whatever trick you try, it won't work, so the answer is the same. And it isn't dogma: conservation of momentum has been verified over and over again.

Some facts: The production of antimatter from energy is a known physical effect, fast moving protons with high energy are collided with stationary atoms and the kinetic energy is converted to mass (protons and anti protons) which did not exist before. E=Mc2 a whole lot of energy is turned into a small amount of mass.

Matter/anti-matter rockets are theoretically possible. However, they would still be rockets, and would work by the same principles as any other rocket. You could make this a chemical rocket, and the results would be the same.

Mass that undergoes acceleration will make an equal and opposite reaction as it is accelerated to the other physical end of the ship.

Which would put stress on the rest of the ship, but unless that rocket is directed so that the thrust
leaves the ship, it isn't going anywhere. The way I read your idea, you were suggesting firing a rocket
inside the ship, then somehow sending the energy from the thrust back to the rocket again. And as I said, you can do anything you want to inside the ship, but it won't matter a bit unless something leaves it in some direction. If you are going to build a rocket, there's no point trying to reuse the energy. Point it outside in some direction and be done with it.
