Inflation Start
We thought we had ended inflation, but we had failed. When you properly account of the quantphysics, it is eternal. And this isn't just that you produce many patches, but the patches will not all be homogeneous. The same quantum physics as producing tis thing means that some of them won't be a smooth and homogeneous patch. Some of them will have variant spectra like we hoped, but they aren't quite what we expected. But i'll give you the horum forum. At inflation start, i managed to get it started. And we thought we managed. We'd better include a little quatum physics in there to make the fluctuations. Soat what it
