Ah OK I see that by adding dS you are in effect including a Bohmian 'quantum potential' term as the gauge here. So yes, it does act as an additional effective force on a putative Bohmian particle that is otherwise behaving classically. Thisis of course how the Bohmian theory regains quantum predictions based on assuming the existence of particles pursuing

deterministic trajectories.

Interesting, although as you know I don't buy the existence of Bohmian particles ;) For one thing, assuming a persistent particle is inconsistent with coherent states that must always have an indefinite number of particles.

Jack that is very interesting. But wouldn't such an exchange give rise to an additional force on the charge--implying a change

I don't understand your question.

The argument below has nothing to do with Jim's gravity theory. It's pure QED.

The result of the local gauge invariance is in this simple case

md^2**r**/dt^2 = e**E ** Newton's second law

from

**P** = md**r**/dt + (e/c)**A**

d**P**/dt = md^2**r**/dt^2 + (e/c)d**A**/dt

**E** = - (1/c)d**A**/dt

Under an internal symmetry local U1 gauge transformation - that conserves electrical charge generating U1(x)

md**r**/dt -> md**r**/dt + h**Grad**S

(e/c)**A -> **(e/c)**A** - h**Grad**S

S = phase of particle's quantum wave function (Bohm)

This is simply an exchange of longitudinally polarized virtual photon momentum between particle (e,m) and classical field **A** which takes time &t

It is the quantum field mechanism for near field electrical contact force.

Under these virtual gauge transformation d**P**/dt = 0, which is the action-reaction principle.

If **A **exerts near field contact force h**Grad**S/&t on e, then e has equal and opposite back-reaction force on A and vice versa.

This is intuitively obvious, elegant beautiful and I have never seen it explained this way before, so I claim it as an original insight in the LOCAL physical meaning

of all internal symmetry transformations and how they connect to spacetime conservation-symmetry laws.

An analogous argument for gravity - is not momentum transfer but proper tensor acceleration transfer between test particle and Levi-Civita LNIF field in time &t,

i.e. the kinematical jerk d^3**r**/dt^3 - mathematically it's the XdX term in the LC LNIF transformation, where X = GCT

{LNIF} -> {LNIF'} = XXX{LNIF} + XdX

**The origins of LNIF and LNIF' are PHYSICALLY COINCIDENT ALWAYS**

ROVELLI EXPLAINS THIS NICELY IN HIS CH2 QUANTUM GRAVITY FREE ONLINE LECTURES

d^2r/ds^2 -> d^2r'/ds^2 = Xd^2r/ds^2 + XdX

This keeps proper acceleration of the test object invariant!

D^2r/ds^2 -> D^2r'/ds^2 = Xd^2r/ds^2 + XdX - XXX{LNIF}X^-1dr/dsX^-1/dr/ds - XdX

= XD^2/ds^2

The "jerk" transferred between test particle and gravity acceleration field (first order non-tidal Newtonian field LC connection of EEP)

is simply XdX/&t from virtual spin 2 graviton exchange. It's not a momentum transfer as in all spin 1 gauge theories.

IN EFFECT

i.e. D^3r/ds^3 = 0

THIS ALSO EXPLAINS WHY ONE NEEDS THE STRESS ENERGY PSEUDO-TENSOR.
