Suppose there is an electron being attracted by a proton. Its position is X0 (roughly speaking) and it is receiving a force F0. Now we try to make a precise measurement on the momentum of the electron. This will increase the uncertainty of its position (become say between X0-dx and X0+dx). Since the force is inversely proportional to distance, the curve is “concave” against distance. The new average force (the area under the curve divided by 2dx) is larger than F0 ! Does the additional force come from measurement ? More broadly speaking, can measurement accelerate most dynamical processes occurring in the Universe ? Information about this Observation

2. No: measurement, does not obviously “accelerate” all dynamic processes occurring in the Universe; as an example, the instruments or apparatus employed for such measurements is not accelerated by the measurement process, although one could argue for a recoil effect based on Newton’s third law .
3. Maybe what is missing here is not just the ‘smoking gun’.

In the language of QM, my argument is that the expectation E(1/x^2} < 1/E(x)^2 for typical probability distribution of x. It is related to noncommutative geometry and the inequality may indicate a subtle effect on the universe. But I don’t know how to get a testable prediction. |
