My how you dance. It was a yes or no question. Do you contend that an EM field must encounter matter in order to be diminished in magnitude or travel X distance? Is it your belief that destructive interference between EM fields does not happen? Those questions only require yes or no answers.
how I dance? hahahahaha
if I dance then you turtle. you never come close to answering direct questions.
your question-
Do you contend that an EM field must encounter matter in order to be diminished in magnitude or travel X distance?
. what the fuck is that supposed to mean? you call everything an EM field without defining anything. if it is a radiative field (light source) then the photon density diminishes according to 1/(distance squared). no photons disappear unless you put a particle of matter in the path to measure it. if you are talking about interference between two radiative fields with photons able to constructively or destructively interact with each other, then if you measure at the point of interaction with a bit of matter you will see the interference. otherwise the photons will pass by each other as if nothing had happened.
if you are talking about electric or magnetic fields it is much more complicated to calculate the force that would be transfered if
and only if, you put a piece of matter that can react with the field into the field. otherwise the virtual photons that make up the field will not be transformed into real photons which transfer force between two particles of
matter. unused virtual photons simply cease to exist before they are in violation of the uncertainty principle and therefore do not need to be paid for.
radiative photons are always real and carry away energy whether they are absorbed later or not.
reactive photons are created specifically to carry forces between two particles of matter in an electric or magnetic field and can be attractive or repulsive.
wirebender- you seem to have the properties of the two all muddled up in your head which leads to massive confusion.
as an interesting aside, one of the many unusual experimental result dealing with photons was found using magnets to polarize a light source. it was found that if the magnet was close to the light source the light polarized, if the magnet was close to the detector the light was polarized, but if the magnet was in the middle away from the light source and detector, then the light was not polarized. in some way the polarization was matter mediated. without matter photons are neither created or destroyed.
