This, to me, seems to be what the quotes want to imply, but I don't immediately see why that should be the case. | |
| Oct 1, 2015 at 12:17 | comment | added | ACuriousMind♦ | @NikolajK: Not sure if that's the question, because there's the obvious counterexample: All of the usual special relativistic QFTs, which have a global, but not local, Lorentz symmetry, but are perfectly consistent local theories. | |
| Oct 1, 2015 at 12:09 | comment | added | Nikolaj-K | I'm certain OP is aware of the first point and is just asking if a global-only field theories must be ruled out for describing physics if locality principles are assumed. | |
