The big question is still why do we have anti-particles at all? Why do they exist in the universe? And so, let's dig into that question and some of the other open questions about antimatter. We try to take every piece that we find and fit it into the puzzle to explain why the universe works this way. The whole thing is a big mess. Is that how you end every physics paper? Yada, yada,. yada, yADA, yada,  and it's all a big Mess. It's a big mess and it's a glorious puzzle and we're still working to try to figure it out."
