I'm part of a games studio who is currently building a game about high energy particle physics (essentially you control a quark and have to try not to get annihilated by anti-quarks), and we're thinking of setting it just after the Big Bang. One idea we've been toying with is that you're essentially playing out the conflict between particles and antiparticles, and that you possibly play in a part in baryogenesis (the process that allowed the quarks to 'win'). As far as I can tell, baryogenesis is still pretty vague. We know that there's CP asymmetry between particles and antiparticles due to the Weak Force, and that this could lead to the imbalance, but from what I've read, the CP violation isn't really enough to cause the imbalance observed. If this is the case, it's a really nice juicy mystery that we could approach in the game. If not, I'm hoping we can utilise whatever else is out there. So my question is: what else, if anything, has been found out about baryogenesis?
