Is the entirety of the quantum zone, in its extent across the contunuum of the cosmos, not bound together by gravity? I mean the complete range of the quantum field, the total breadth, depth, width and height of the zone considered to be quantum? If not, then what defines the boundary of the quantum, and macro realms of existence?

How is it possible that something can be at rest in space but moving through time? If it moves in time it also needs to be moving in space, say, a gravitational field, isn't that right? Obviously I'm wrong, but this seems so paradoxical.

In the double-slit experiment with single electrons, if the lateral position is measured very precisely (more than enough to know "which slit"), will the math model of the experiment predict successfully where the electron will strike the screen?

Given that (according to quantum mechanics) there is a non-zero probability of finding an electron anywhere in space, is there non-zero probability of finding an atom of my body on the Moon? If "yes", is that claim falsifiable and how exactly?
