I'm not sure what you mean by this. As has already been pointed out, the uncertainty principle does not constrain the variance of...

Statistical uncertainty, which is not the same as the "uncertainty" part of the uncertainty principle. I'm not sure the OP grasps that...

That was not at all clear, and the OP question is about the uncertainty principle.

This has nothing to do with the uncertainty principle, because we are not looking at the probabilities of results of future measurements...

Mathematically, the uncertainty principle sets a lower limit on the product of the variance in position and the variance in momentum...

"Uncertainty" as in the uncertainty principle is not even about the variance of a large number of measurements of a single observable...

Note that we don't have light sources that allow us to control when a photon is emitted. The best we can do is to turn down the...

And that being so, I have removed that part of the thread title.

More precisely, she figures that that is the elapsed time that an Earth clock will show at an event on Earth that is simultaneous, in...

I don't see why, since QM interpretations that do not say that the state vector represents the complete description of the system still...

Hm. Their statement "standard quantum mechanics, where the state vector is assumed to provide a complete description of the physical...

I still don't understand. You say: Which already tells you "which of the propagation pictures discussed around post #95 is closer to...

Mathematically, the way QM arrives at its prediction is clear: each individual photon's wave function contains inteference terms, and...

OK, so the test you are proposing is actually not a strong test of this. If you want to test for “apparatus history” you would want the...

But it would cost time and effort that could be spent on something else. And since, as I've already pointed out, the hypothesis you say...
