<p>[01:10:23] Let's get started. We take $$X^4$$, we need metrics. We have none. We're not allowed to choose one. So we do the standard trick is we choose them all. | <p>[01:10:23] Let's get started.

<p>[01:10:36] So we allow $$U^14$$ to equal the space of metrics on $$X^4$$ pointwise. Therefore, if we propagate on top of this, let me call this the projection operator. If we propagate on $$U^14$$ we are in some sense following a Feynman like idea of propagating over the space of all metrics, but not at a field level. | <p>[01:10:36] So we allow $$U^14$$ to equal the space of metrics on $$X^4$$ pointwise.
