It also has absolutely nothing to do with quantum mechanics per se. It's gravitational physics whereas even a proton is merely QCD. The length scale at which the motion of a baseball is quantum mechanical has absolutely nothing to do with either. Locality is a statement about the interaction of physical systems that are in different points in space. No such interaction exists. Again, all non-locality violates quantum mechanics. Bell and other are simply using the wrong terminology. | |

| Jul 21 at 4:46 | comment | added | KDP | @FlatterMann the Planck scale is orders of magnitude smaller than a proton radius. John Bell himself said ""If [a hidden-variable theory] is local it will not agree with quantum mechanics, and if it agrees with quantum mechanics it will not be local.". Entanglement is non local unless you subscribe to one the weirder interpretations of quantum physics like determinism or the Many Worlds interpretation or Pilot Wave Theory. They are all convoluted attempts to overcome the problem of non locality, when it is not a problem in the first place. | |
| Jul 20 at 23:11 | comment | added | FlatterMann | Entanglement is neither non-local nor instantaneous. Both terms would describe physics that breaks relativity. Entanglement does not. The idea that the Heisenberg uncertainty relation somehow dictates length scale is also completely wrong. It has an angular momentum/action scale but NOT a length scale. Heavy objects behave perfectly classical for scales that are much, much smaller than e.g. a proton radius. | |
