As if. Yes. But my point is that the FTL is enforced only by asking measurement to have unique outcomes. That never appears without collapse. > However, when you consider that what is instantaneously changing is the wf, > which exists in the complex plane, it is arguable that any kind of velocity > is involved. AG Even in the purely mathematical description, the result of interaction (like when we do a measurement) propagate at the speed of the contagion of the local interaction. There is no instantaneity anywhere once we abandon the idea that a measurement collapse something.
