One of the persistent problems in science is the reconciliation of Newtonian objective mechanics and quantum mechanics; quantum mechanics’ domain is the atomic one.
Physical objects are independent 3-D shapes whose existence is independent of the observer. Newton’s laws describe the motion of these objects with other objects. Newton’s equations, or laws, work and are not questioned here.
However objects are imagined to be fabricated from atomic particles; particles are not objects but imaginals.
Those particles are not objects in the Newtonian sense and his laws are thus not applicable to describing their imagined motion, if any.
No one can handle an isolated proton, electron or neutron: they are all imaginary constructs and under no circumstances an object in the Newtonian sense.
But we imagine they are objects and thus assign properties to them that are subsequently learned to be inexplicable.
It’s because of the way we think.
Einstein fabricated relativity because all his efforts were confined to the imaginal world in which he lived; he was totally in thrall of his imagination, but unlike the Red Queen, imagined a bit more than six impossible things before breakfast.
He imagined that Time was a physical thing; it’s not, and it strictly an imagined abstraction. Time is not physical. Time is simply based on the observation of a repetitive physical phenomena such as an orbiting satellite around a star or planet. Or one could look at an analog clock and wonder when it started ticking.
The problems of Quantum mechanics arise because we ignorantly extrapolate the physics of objects to the microscopic domain in which objects do not exist; Newton’s laws are not applicable at that level, and thus those “imaginals” have no shape, mass nor independent objective existences.
