Now there's a huge problem in the spinorial sector, which I don't know why more people don't worry about, which is that spinors aren't defined for representations of the double cover of \(GL(4, \mathbb{R})\), the general linear group's effective spin analog. And as such, if we imagine that we will one day quantize gravity, we will lose our definition, not of the electrons but, let's say, of the medium in which the electrons operate. That is, there will be no spinorial bundle until we have an observation of a metric. So, one thing we can do is to take a manifold \(X^d\) as the starting point and see if we can create an entire universe from no other data—not even with a metric. So, since we don't choose a metric, what we instead do is to work over the space of all possible point-wise metrics. So not quite in the Feynman sense, but in the sense that we will work over a bundle that is of a quite larger, quite a bit larger dimension.
