I am not sure if this is the appropriate topic, but here goes ...

Thoughts about the photon.

A photon is a quantum of electro-magnetic energy (EM).

A photon is thought to be a disturbance in the light-carrying-medium (LCM).

Photons travel through the LCM at velocity c, the speed of light.

Photons are detected as waves (transverse waves?) in the LCM.

Photons are detected as particles (longitudinal waves in the LCM?).

The wave aspect of photons has a frequency, which is proportional to the energy of the photon.

Photons can be entangled in such a way that the determination of the state of one photon causes an instantaneous

assumption of a predictable state by the related photon, regardless of its location. This implies a connection (in another

dimension?) independent of 3D space.

Is there a maximum limitation on photonic intensity (an upper limit on the photons per centimeter squared) at the point

of emission?

Is there space between photons from the same source, far away from the source (the photonic intensity per cm^2

should decrease proportional to 1/4piR^2 where R is the distance from the source)?

If a photon encounters opaque (for its frequency) matter, it may be reflected, or it may be absorbed, in which case it's energy is converted to some other form.

As the photon proceeds through space there is some non-zero loss of energy, probably due to friction within the LCM.

This change in energy is manifest as a change (reduction) in the frequency of the EM wave aspect of the photon over

distance.

How far will a photon travel (until its EM frequency becomes zero?)? This must be the fate of almost all the photons, however generated, within the universe.

What happens to the energy contained in the photons that never encounter matter?

Answer: The energy of dead photons is obviously absorbed by the LCM. (Does the LCM consist of dead photons then?)

Is this the source of zero-point energy (ZPE)?

I am feeling a bit confused. Please label any of the above assertions true or false and feel free to respond to any of the questions.
