| Sep 10, 2020 at 9:00 | comment | added | thunderbolt | Not sure if this is what you're asking, but this reminds me of something I encountered in QFT. Basically, the propagator of, say, a scalar field theory is non-zero even for spacelike seperated points (the fuzziness you're talking about reminded me of this point). But when you calculate the commutator of spacelike seperated fields, you find that the contributions from the propagators cancel out to give zero. This means that there should be no observable consequence of some perturbation on points which are spacelike separated from the point you perturbed. | |

It is really interesting to see that you had the exact same thought as me. Now I find it much easier to believe that people can independently discover similar things around same time | |
