I really don't want to take up the time of everyone on this list with
basic physics.
 
The proof I referred to is Noether's theorem.
The characteristic of space-time required is time translation symmetry.
Even relatively minute deviations from this symmetry would be
immediately 
detectable in everyday life. So I think we can count it as extremely
well-grounded empirically.
 
Conservation of mass can not be an axiom. 
It is simply wrong, as Einstein figured out in 1905 (clue - E = M c^2).
 
The commutativity of addition (1+2 = 2+1) can be directly derived from
Zermelo-Fraenkel axiomatic set theory.
However, axiomatic set theory obviously has axioms, as does Euclidean
geometry.
So your point that we need to assume something is correct, you merely
used bad examples.
However, math and the natural sciences try to assume the absolute
minimum number of axioms
(and to make these axioms as well grounded as possible)
and to prove the most from them. 
It would be useful for you to state you axiom set, and to show us in
each case how you
derive your results from this set.
 
I would like to reiterate that I never singled you out for bring no
proof, 
and certainly was not the one to say "silly" or "funny".
I have a great appreciation for your contributions here.
 
Can we now get back to discussion of biblical Hebrew
rather than physics and ad hominem arguments ?
