The Hilbert Space of Quantum Gravity Is Locally Finite Dimensional
In any one region of space, all you need is a finite dimensional Hilbert space to describe what's going on. Are there an infinite number of regions of space? Something we don't actually know.

The probability that a bunch of very unlikely things happen in the Everady and multiverse is just really, really tiny,. Just like it is in quantum mechanics.
