The rate of expansion needs to be proportional to distance - otherwise the expansion would have a fixed central point, which we know is incorrect. Secondly the expansion needs to be rapid enough to reproduce the very smooth and flat density pattern that we see in the cosmic microwave background. See en.wikipedia.org/wiki/Flatness_problem for more details. | |

We see no magnetic monopoles today. Inflation explains this by providing a mechanism for dispersing primordial magnetic monopoles. See en.wikipedia.org/wiki/…. | |
