What is the fabric of space like at the interface point of physical and quantum?

Given:

- the essential laws of physical space--eg. .a moving object travels in a straight line in the absence of external forces

- and that quantum space doesn't seem to follow the same rules

is anyone addressing this assumption: that at the quantum level, the fabric of physical space is porous. we observe the quantum as it interfaces with our physical. Can a particle move back and forth across the threshold? What's the interface like? If we're viewing a particle as it shows characteristics observed in quantum space- movement, etc could the bent shape of physical space not explain the objects movement as it travels in a straight line distance in quantum space? [eg. at the quantum level, if a partical enters/exits physical space, and our physical space is bent back on itself, then a particle moving across that threshold would appear to disappear from one spot and instantly reappear in another part of physical space. [Non-physics person, so please explain w/o formulas, if possible.]

There is no such thing as physical and quantum space. They are both the same thing, viewed at different magnification.

Newtonian physics were correct (and still are correct) for large objects moving at low speeds. Since our measuring capablities have increased we started noticing that more laws are needed to explain the behaviour of very small and very fast object, hence we we developed quantum mechanics and the theory of relativity.

Quantum mechanincs assumes that some physical quantaties are quantitized, that is they come in indevisable amounts. For example the potential energy of an electron in a hydrogen atom is quantitzed. So is its angualar momentum and a spin.

The electron's position (i.e. space) is still assumed to be a continuum, that is the electron's position is not quantitzed and it can occupy all positions in space.

It may well be that space is also quantitized, however we have not been able to achieve a technological breakthrough that will allow us to probe such small measure.

If you want a simple demonstration then look at any smooth metallic surface. To the human eye (and touch) the surface appears smooth and straight. However if you use a powerful enough microscope you will see it consists of billions of ball shaped atoms so the smooth surface is actually built of many many balls stuck together. Does that mean that the surface is not smooth? No! For all intents and purposes it is smooth because you percieve it as such.

The same is true for space. Even if a particle does "hop" from one point to another, those points are so closed together that even today with all our advancments in sub-atomic studies, we still can't tell if there is or if there isn't an intervail between two adjacent point in space.
