Oh I just realized that, since we're playing a little fast and loose with physics, that if Hymn manages to start making the portals non-identical, she could start fucking with the chirality of particles that come through. Oh man once she grows a little it's going to be [b]antimatter zeit[/b]

If we consider physics a video game, the fact that we essentially have defined the "game engine" ourselves here means that we can alter the behavior of several physical properties without actually violating any laws. Antimatter is also entirely fair game.
