Question: Where did all the antimatter go?

I’m not an expert on antimatter, but this article explains it really well: http://united-states.cern/physics/antimatter – I think the key part is that scientists think that the laws of physics might not apply equally to matter and antimatter, and both types of particles might decay at different rates, leaving over a little more matter than antimatter. I think I’ll have to read up on this more too. 🙂
