Episode notes

This is probably not accurate, but this is the best calculation we could do. It's an absolutely correct calculation given the mathematical and physical model that we constructed. But does it make sense? No, it doesn't. If we believe the universe is 13.8 billion years old, 15 is ridiculous. Yet it is correct from mathematics. Yes, it is not incorrect because this is what I calculated. Nobody made a mistake. So you're saying physicists are much closer to truth than mathematicians. Well, it depends. It depends. Sometimes yes and sometimes no right.
