Is your intention to explain everything? If so, I have to say "I think it is
impossible."

There is no symmetry between LS and space-time at least in LS theory. LS
theory assumes the existence of space-time for each LS. Probably, the problem
you raise here is that we have a common space-time. My point in LS theory is
that that is only an assumption that cannot be verified, and that it is a
thing that we assume. This is the reason why I impose axioms 4 and 5. This
assumption remedies people from their "common" universe being chaos. But note
that, at the deepest level, there is no assurance that we can have a "common"
universe.

This is another way of

There are many objects for every LS.

Mapping from where to where? Namely what are the domain and range of your
mapping?

Subject-object relation is not symmetric, because the outside of an LS
consists of an infinite number of particles that cannot be reduced to an LS
which has a finite number of particles, while inside an LS there are only a
finite number of particles.

What he writes around page 446 are quite elementary things well-known to
mathematicians. How do you intend to utilize those?
