In fairness, Antiprotons and protons are not exactly [i]opposites[/i], it is just changing one attribute of the "particles" [the chirality]. It is also not particularly hypothetical: people have produced antimatter and the equations for the energy emissions fit with experiment parsimoniously. That being said, I am all for not letting it happen: I am assuming some level of scientific literacy for Billy, but him not only understanding what antimatter is but understanding it well enough to create it from normal matter seems a little far-fetched. I think I'll cast the spells to detect life in the offices, then bore through with a few people, then blow people up and claim the elevators, then begin moving towards where Blackwell should be to protect him and hopefully extract him from the ministry. I'm more busy than I'd like to be, but I'll make sure to get a post up either today or tomorrow, sorry for the delay.
