Now, you may have heard me say that we have this thing called effective field theories, right? If you don't want to extend your field theory to arbitrarily high energies, then we can just say we have a cutoff, we have an energy scale above which we don't care, and make a theory about what happens below that scale. And that you can do for gravity, and it works in a wide variety of circumstances. But
