The Big Bang and Inflation

We're talking about what might be causing inflation. But first we talked about sortof why inflation makes sense, because it is a crazy idea. Andi make some predictions, which we can verify. Rate, you have to cast your mind back about 20, 25 years before we had really detailed measurements of the cosmic microoid background radiation. They said, if you measure this really, really carefully, you'll find that it's not all the same energy photons, you should see wiggles. We saw exactly those wiggles that inflation predicted, right?
