Electricity, magnetism, gravity, matter, nuclear forces et cetera are what we call physical manifestations and are measurable. They give us our reality. But they can also be thought of as the projection from a deeper reality. As mentioned elsewhere, the Christian development of science had this idea at its base – Newton, Galileo, Boscovich, Lemaitre etc. It is only in the last couple of centuries or so that the materialist view has come to surmise that electricity, magnetism et cetera are the fundamentals reality.
While Christians see these concepts as emanating from a greater, hidden reality, the materialist has to explain all reality in these (or similar) manifestations. I think quantum physics has ruled the materialist view as untenable.
As mentioned above, the whole of creation can be thought of as a projection, but there is a problem with us being able to understand and explain it. If we are limited to 3 dimensions we cannot fully understand the workings of projection from a fourth dimension. From our limited position of three dimensions (plus time) we cannot in theory overcome the ontological differences to examine and explain interactions with higher dimensions.
If our world consisted only of a projector screen we could only infer the projector from the changes to our world (the screen). In order to explain the interaction effectively we would have to step off the projector screen (our world). Likewise, in order to explain the detections from the immaterial world we would have to be set free from our three dimensional space.
With quantum scientific concepts of complementarity, observer effect and non locality there is a level of reality which is at the base of our reality, but from which we are barred from examining and controlling. This by definition is the immaterial.
If we take the example of ‘quantum tunnelling’ what we call ‘matter’ jumps across space without travelling through the intermediate space. We are left with either assuming our reality includes non causal discontinuity (but then we have to explain why it looks causal to us and why it obeys mathematical law) or surmise that there is still causality, but it is not material (in our world) and therefore matter is a projection from somewhere.
This by definition is the immaterial. We can detect quantum tunnelling, but we can’t explain it. If we want to keep causality then the immaterial must come into play when we study the workings of quantum physics. Hence the plethora of modern scientific guesses of String Theory, parallel Universes, Multiverses et cetera. These too, are immaterial by definition.
