It's the difference between kinetic energy and suchlike, and mass-energy equivalence.

Let's just assume that the usual QM stuff does apply and I'll choose the Copenhagen interpretation of QM for this problem.And there is the source of your conundrum. All the stuff about measurements and wave function collapse are reasonably predictive models of reality but can't claim to be reality.
What is this life if, full of care,WH Davies,1911.
We have no time to stand and stare.
No time to stand beneath the boughs
And stare as long as sheep or cows........
The word has two different meanings (a) representing a continuous function with a discontinuous function and (b) modelling the behavior of electromagnetic radiation as a stream of particles each having a discrete quantity of energy.Quantisation in analogue to digital converters and quantisation of photon energy are entirely separate phenomena.What makes them different?
Although uncommon, it is possible to die during sleep from untreated obstructive sleep apnea. Observational research has found that OSA increases a person?s risk of sudden death. This risk is believed to be higher in people of older age, in people with a critical illness, and in people with severe OSA.
Most of the time pauses in breathing from obstructive sleep apnea are just temporary. When changes in respiration cause oxygen levels to drop, a person partially awakens in order to restore breathing. However, there are rare reports of people dying because of an inability to properly reinitiate breathing.
When OSA is not treated, it can also interfere with the normal functions of the cardiovascular and nervous systems. This may provoke abnormalities in a person?s heart rhythms and other problems that can cause sudden cardiac death.
I don't recall Newton ever saying that gravity was the gradient of a potential. It is just the force that a unit mass would experience when it is put somewhere.No. It is (and always has been) an attractive force between masses. The vector has magnitude GMm/r2 and direction toward the barycenter of the masses. In the absence of a barycenter it has no direction.
there is no reason why a well defined gravitational field g can't exist throughout space
