Dear Anshu,
Thank you very much for your comment. To understand the resolution to this issue you have to see that the concepts within the Spacetime Wave theory mean that there is no longer a need to make a distinction between quantum mechanical and classical behaviour.
These labels are no longer helpful.
When you say that electrons are quantum mechanical that means that you are saying that they are modelled by the wavefunctions of quantum theory. The behaviour of the electron does indeed fit with these wavefunctions and the electron in the context of quantum theory is endowed with all of the concepts that go with quantum theory namely: wave/particle duality, the uncertainty principle, the measurement problem, the collapse of the wavefunction etc.
With the Spacetime Wave theory, things are much simpler. The electron is a looped wave disturbance of spacetime. It is a real physical wave. The problem of the collapse of the wavefunction and the measurement problem is resolved by realising that any detection of a wave involves an interaction between, for example a photon (as a wave disturbance of spacetime) and an electron of an atom (which is a looped wave disturbance of spacetime).
The wave disturbances of spacetime are by their nature dispersed in space and the nature of this dispersion can still be modelled using the QM wavefunction. The idea here is to use the wavefunction (which in QM describes the probability of finding a (point) particle at a particular position) as a measure of the magnitude of the real physical wave of the Spacetime Wave theory at any point. The progress of the wave is precisely determined and probabilistic effects only come into play when the wave is detected or absorbed. The detection has the effect of localising the dispersed wave.
It is hard to set aside the interpretational ideas of quantum theory but I do believe it will be possible to show why the equations of quantum theory work as they do in the context of a real physical description based on the Spacetime Wave theory.
When we talk about matter sources we are talking about any object with mass. So an electron is a matter source and it has mass because it is a looped wave in spacetime i.e. it is a source of spacetime curvature. This then explains how mass curves spacetime. Also it reacts to spacetime curvature, seeking to move to a lower energy position based on the curved spacetime environment that it finds itself in.
So in a sense you could say that the Spacetime Wave theory is a classical explanation of atomic phenomena as it does not follow the Copenhagen interpretation of Quantum theory.
I hope this helps.
Best regards
Richard
