No, Guys, That's Not How Inflation Went

Sean Carroll is blogging about his new arXiv paper, in which he and Grant Remmen analyze a couple of inflation models to see how likely it is that they produce enough inflation to explain why the universe is so flat and smooth. It’s interesting work, but not very useful because, as I told you here, inflation didn’t happen according to those models or any of the other inflation models the physicists have proposed. As usual, it comes down to whether your spacetime model is correct, and theirs ain’t.
