We assume that the doppler shift is due to motion, based on our understanding of light. What if it isn’t?

Interesting consideration, except I believe we are able to observe the Dopler affect on light through other verifiable science and experiments. I recall experiments with prisms and solar eclipses or something. ;o)

That said, I would not rule out the premise of observable light being misinterpreted. It would set science as we know it on its head. It would be like Galileo and/or Einstein scientific revolution and controversy. BLASPHEMY! ... and all that.

E = mc2 is true for the special condition of Time being a linear phenomenon. It does not hold for Time when Time expresses in planar fashion. It is the existence of this planar expression dimension Time that gives rise to the zero point field, IMHO. It is also why there is electro - magnetism ... the stretching effect of Time from linear to planar manifests the magnetic expression of the energy imparted at initial conditions of Creation.

The first command, 'Light Be' is the result of spacetime having linear and planar and volumetric reality such that wave function can occur. The collapse of the wave function is the effect of 'selection' of a linear expression of the temporal nature of the wave form.
