All this time I thought it was a big mystery why there's more matter than anti-matter, but now you're telling me we've known this whole time that the rules were different between them? All we're waiting for is to find out what specific processes made it work out? I've always gotten this breathless "how could it be?" impression when people talk about that issue.


CP violation is a necessary component, but it doesn't completely explain the whole matter-antimatter asymmetry.

We still haven't ever observed a process that doesn't conserve baryon or lepton numbers, which is another crucial component.


To be fair, that's a pretty common reaction to most of advanced physics.
