<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.
