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.
