Streamed live on Dec 22, 2025.

Shortly after the big bang there were almost exactly the same
amounts of matter and antimatter in the Universe, but there was
just enough of a difference that we live in a matter-dominated
Universe. But it didn’t have to be that way! Explaining this
mystery has been one of the great mysteries in astronomy, and
today we’ll see if there’s been any progress! Why is the Universe
the way it is? Specifically, why is it made mostly of matter?
This is the question we'll look at today!
