If light lost 3 dimensional polarity and photons traveled only on an arbitrary plane, would we see in the second dimension, provided our brains compensated for the image created? This of course assumes not that a single plane exists in the universe, only that light once created may only traverse back and forth on 'x', a randomly created finite line in space thus preserving the wave qualities of light, frequency, wavelength and speed, essentially asking: what would happen if you made light 2 dimensional? If this were true and dimensional vision were simply a matter of the properties of photons, couldn't we see into the 4th dimension if photons also carried with them all temporal information and we had organs to decipher it? One could say that the eye would be able to tell the brain about the origination of a particular photon and the various mediums it has traveled through (disregard the complexity and shortfallings of cellular mechanisms and current biological capability). So since we are already able to receive photonic information, with this additional dimension we would see something like all the states of change a body has been and will go through simultaneously, or however the brain wishes to project an image of the 4th dimension. The question assumes that introducing 4th dimension information to the photon (if it doesn't already have it) or suppressing its 3rd dimension quality would change nothing significant in electrodymanic interactions (a heavy assumption). It also assumes that we would have the appropriate ability to capture that radiation.
