There is no instantaneous remote action. The only fact is that all force fields are co-moving with their source.

If we measure the intensity of a force field exerted by a moving source, then the field strength matches to the current (not retarded) position of the field source. This leads to the impression that the source has explicitly emitted the field with an infinite propagation velocity. But in fact, the field is only co-moving with its source.

If the field source gets accelerated, it radiates. The aperiodic part of the radiation adapts the field to the modified movement. But this adaptation propagates with the speed of light.

"There is no instantaneous remote action. The only fact is that all force fields are co-moving with their source."

I find it difficult to accept this for far-field interactions.

Emmanouil Markoulakis "I find it difficult to accept this (fields co-moving with their source) for far-field interactions."

Yes, but if we consider the force field in the rest system of the field source, we see that there is no other option.

Indeed it is not obviously plausible that for example the gravitational field of a single electron reaches over light year distances with an unimaginable small amplitude.

Also the electrical field has this unlimited extension. But in most cases the electric field is compensated by fields of opposite charge.

Dear Wolfgang Konle ,

I agree this is the most probable explanation (i.e. rigidness of static fields with their point source) given our current understanding of physics. Which however is not possible if free-space is not considered as a quantum medium and some kind of material, thus, no action can be considered anymore as remote, everything is connected via free-space which is not free or empty.

Vacuum is not synonym with void.

Kind Regards,

Or, what I consider as being more probable, the static field including its source is the quantum medium. The quantum is the elementary particle, including its surrounding force field(s). The force field is in plural because gravitational, magnetic, and electric fields exist.

The free space only is a container without any interaction properties with matter and energy.

But according to Einstein's field equation with a positve cosmological constant Λ and a zero energy momentum tensor, the free space can contain an energy density, which warps space. The space then has a constant scalar curvature of 1/R² and a volume of 2π²R³.
