During the Big Bang there was matter and antimatter. We can make antimatter in our accelerators, but it doesn’t exist in our universe in any substantial form like this. When we make antimatter, we always make an equal amount of matter with it—that is the law. So in the Big Bang there should have been equal amounts, but now all the antimatter is gone.
Where did it go?
This is one question we’re hoping to answer. What is this asymmetry that allowed matter to win over antimatter and for us to be here? It could’ve been a universe of just light.”—Tom Littlewood’s interview with Lyn Evans, Large Hadron Collider Project Leader. In Vice Vol. 16 No. 6
