>What happened when inflation stopped?
>The best guess as to what happened (and our equations show this is possible, but don’t tell us the details) is that all that dark energy got turned into particles — including particles we’re made from, and lots of other types of particles we know about, and perhaps lots of particles we don’t know about. And when this happened, the universe became very hot, and very dense — and it continued expanding, though much more slowly.
