Questions about the sciences of freedom

Hello Rabbi
I looked at the book The Science of Freedom after being referred to it. Several questions:
1) From what I understood, a voluntary action would be performed by creating a force field (say) that would affect the movement of particles, etc. I didn’t understand how this fits with your assertion that the physical world is constant and has no spaces. If there are no spaces, then how is it possible that I, by my choice, would “invent” a force field out of thin air? After all, you say that the system is constant and has no spaces, so where is the place to introduce an “electric field” into this, if there are no spaces?
2) In the spirit of the first question – from what I understood from you, you do not advocate the “God of the Gaps” method. But aren’t you relying on the fact that it is not yet possible to explain the entire human nervous system as a direct and absolute result of data transmitted to the brain? According to you, my consideration lies somewhere in the middle. And the very fact that it has not yet been proven that it is possible to see a complete connection between what is given and what is done in the end, is what gives me the possibility of saying that I have a choice in the middle. But isn’t this the God of the Gaps argument? That science simply has not yet been able to prove this from its experiments, but it is still possible to prove it?
3) Why do you say that it is more likely that the brain creates a force field rather than electrons? What is the difference? Does this have any implications for the previous question, of what can be proven experimentally and what cannot be proven?
