Ep. 776: The Matter - Antimatter Dichotomy

Astronomy Cast Ep. 776: The Matter - Antimatter Dichotomy By Fraser Cain & Dr. Pamela Gay 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!
