[QUOTE="Morbert, post: 6862486, member: 664826"] It's the meaning of these world lines and tubes that I am curious about. If we say that, in classical physics, normalised density operators are to replace phase space variables as the objective properties of the system, then if I have a toy ball on a spring, the real properties of the ball are not its position and momentum, but rather those properties for which, under the right condition, statistical properties are arbitrarily close. But maybe this is fine, and the objective properties of classical theories are also density operators but with zero quantum deviation. Maybe there is a future paper "Classical Tomography Explains Classical Mechanics" [/QUOTE]
