I spend a lot of time on this blog explaining a
physical spacetime model and the underlying metaphysics. In this series of
posts, each entry poses a physics question for the spacetime model, along with
the answer. A separate series of posts answers metaphysics questions.

**Physics Question #2. What is the inflaton (the field responsible for cosmic inflation)?**In my spacetime model, spacetime is self-generating. Spacetime itself is the inflaton. Points are defined recursively, with the result that the number of points increases from N to 2

^{N}at each discrete time step. This is an extremely rapid expansion. It never stops, so spacetime is always inflating.
