Electric force is real because it pushes charges off timelike geodesics of Einstein's geometrodynamical field, i.e. the Ruvwl curvature tensor field, which can be zero of course - zero is a good real number.

My point is perhaps a bit surprising.

The canonical 3-momentum of a charge e of mass m is

P = mV + (e/c)A

Total local momentum of the charge + EM field = Kinetic momentum of the charge + EM field momentum

A gauge transformation is

mV -> mV' = mV + hgradf

(e/c)A -> (e/c)A' = (e/c)A - hgradf

http://www.ippp.dur.ac.uk/.../QED/GaugeInvariance_2.html

Therefore the canonical 3-momentum P is gauge invariant.

h is Planck's constant, so this is a quantum effect in what first appears to be a purely classical problem.

First surprise!

From the point of view of local field theory if we suppose that the charge and the field at the charge are a closed system so that

dP/dt = 0

then what we have is simply a Newton third law

ACTION + REACTION = 0

where

mV -> mV' = mV + hgradf

is the ACTION of the electromagnetic field A on the charge e of mass m.

(e/c)A -> (e/c)A' = (e/c)A - hgradf

Is the equal and opposite REACTION of the charge e on the field A

This is a LOCAL exchange of a virtual photon of momentum hgradf between COINCIDENT charge and field.

The classical equation of motion in an inertial frame follows trivially

dP/dt = mdV/dt + (e/c)dA/dt = 0

E = - (1/c)dA/dt

Therefore

mdV/dt = eE

Now I can do the same thing for Einstein's GR using the Levi-Civita connection, where now, instead of virtual momentum transfers between particle and field, we have real proper acceleration changes between locally coincident LNIFs measuring the motion of test particles that keep the proper forces on the observed test particles a tensor. This gives direct physical meaning to the inhomogeneous terms in the non-tensor Levi-Civita connection transformation induced by the formal general coordinate transformations. In other words it is a heuristic physical picture of gravity gauge symmetry on the Levi-Civita connection, which is not a tensor.

Imagine two bricks taped together with a dynamite stick and timer released from an airplane

The dynamite explodes

There are transient real electric forces on the shattered brick pieces momentarily pushing them off their geodesics
After a while these forces vanish and all the pieces relax to geodesics
Where is the beef?

The fact is that Jim uses an undefined primitive he calls "inertial reaction force" that has no relation to anything in textbooks on the subject unless he means

F = DP/ds

Jim has never given me a straight answer and I cannot find a clear definition in his book either.

Any suggestions?

But I should add that Jack can give a 'substantivalist' account of what you describe by appealing to the constraining effect of spacetime to keep the remaining block on its geodesic. What you describe as an inertial force, Jack describes as geodesically-constrained motion. Different, irreconcilable, metaphysical pictures. (I happen to question the substantivalist idea that spacetime has these sorts of causal powers. But that's the mainstream view.)

## Higgs, strings, gluons and Einstein's gravity

Posted by: JackSarfatti |

Note that the total energy of the gravity field has this Q problem suggesting gravity as a "More is different" (P.W. Anderson) low-energy emergent field from a spontaneous broken vacuum symmetry at the Alpha Moment of Inflation (zero conformal time & zero comoving distance in Tamara Davis’s Fig 1.1 c) from false to true vacuum in the above picture.

On the other hand gravity is also induced by localizing the universal global gauge (De Sitter - Poincare group) - so how do we merge these two ideas from different levels?

One model is G = O(9) spontaneously breaks to H = O(8) giving 8 Goldstone post-inflation condensates whose quantized vibrations are the massless SU3 QCD gluons via an analytic continuation of non-compact O(9)/O(8) to compact SU3?

This model has 28 Higgs-like massive bosons - not to be confused with the single electro-weak Higgs allegedly now found at LHC from G = U1xSU2 ---> H = U1 where the three massless W bosons of SU2 essentially absorb the three massless Goldstone bosons leaving only the single massive Higgs boson in this simplest of models.

28 + 8 = 36 = 9x8/2 = number of spacetime charges in string theory type O(9) spacelike sub-group of string theory O(1,9) with 6 extra space dimensions.O(9) is for the spacelike slices of O(1,9) used in superstring theory
