Antimatter Rocket Propulsion

This is basically a long write-up I made about antimatter rocket propulsion. I’m still learning, so a lot of the maths and ideas are from reading online papers and trying to understand how proton–antiproton annihilation works. I tried to model how the energy splits into pions, how a magnetic nozzle could maybe push them into a single direction, and what kind of speed a spacecraft could reach if everything worked perfectly (which it probably won’t). The paper is not based on real experiments or anything like that because obviously I don’t have access to that stuff. It’s all theoretical calculations, simulation ideas, and concepts based on what current physics says. I also wrote about the problems, like how impossible the antimatter production is right now, and how the heat and radiation would be insane to deal with. I’m just sharing this because I’m interested in space propulsion and wanted to see how far the physics lets you push things. It’s not perfect and there’s probably mistakes, but hopefully someone finds it interesting or helpful.
