Georgina,
"For vision there has to be receipt of sensory information, in the form of photons providing frequency and intensity data. It is just information. Yet Relativity does not take account of that, and so the things seen are regarded as Objects themselves."
I accept that colloquialisms have a utility in logical discourse, to summarize otherwise lengthy detail. But. (1) sensory information is confined to the physiology. (2) photons exhibit frequency and intensity but only transport energy. (3) the data is provided by the generality of Maxwell's equations. (4) Relativity takes all that into account, it says so in the title. (5) things seen are not regarded as the objects themselves, refer to (3). (6) people start learning about subjects without prior knowledge, so there is not sufficient 'knowns' to support full incorporation of knowledge as 'information'.
It may be common in discourse to speak of 'a red photon', or that the photon 'carries information' that the apple is red. Those are colloquialisms. There is quite literally no experimental evidence that 'red' exists anywhere other than the mind. Yes, I said that. What makes anything visible is just as dark as any other region of the spectrum. What can be said is that what we do know something of, is only the response of a detection system and to a lesser extent through deduction, the behavior of an emitter. That is the science (not much, eh), not the psychology, metaphysics or philosophy. How could a photon provide information when science can't agree on what it is? Some says its a flower, some says its a weed. :-) jrc
