Amongst other things on my essay blog you pointed me to your comments on SR.
Now, had Einstein done what he said he was going to do, then it would be a 'theory of the relativity of information' (as you phrase it). But he didn't, so it isn't. It is just wrong.
There are two phases to explaining this:
1 What actually is SR.
As defined by Einstein, SR involves:
-only motion that is uniform rectilinear and non-rotary
-only fixed shape bodies
-only light which travels in straight lines at a constant speed
In other words a state of stillness where nothing, relatively, is happening. It is special because there is no gravitational force (or more precisely, no differential in the gravitational forces incurred). It is not 1905, but his attempt to resolve the 'apparent irreconcilability' of the two postulates. Had the light in Einstein's second postulate been observational light, ie light which enables sight, which is what it was meant to be, then this state is the only circumstance in which the two postulates reconcile. But there is no observation in Einstein, because there is nothing to observe with. There is always some form of light, but it is just being used as a constant against which to calibrate distance and duration. Nobody sees with it. So the second postulate was not deployed as defined, and the attempts to reconcile rate of change and constancy of light speed are pointless, because the issue is non existent.
2 So the question becomes, what is relativity. The closest Einstein got to admitting what he had, in effect said, is:
Einstein para 4 section 9 1916
"Events which are simultaneous with reference to the embankment are not simultaneous with respect to the train, and vice versa (relativity of simultaneity). Every reference-body (co-ordinate system) has its own particular time; unless we are told the reference-body to which the statement of time refers, there is no meaning in a statement of the time of an event. Now before the advent of the theory of relativity it had always tacitly been assumed in physics that the statement of time had an absolute significance, ie that it is independent of the state of motion of the body of reference. But we have just seen that this assumption is incompatible with the most natural definition of simultaneity; if we discard this assumption, then the conflict between the law of the propagation of light in vacuo and the principle of relativity (developed in section 7) disappears".
What has happened here is that since he conflated reality and the light based representation thereof, because he has no observational light, he has confused the time of occurrence of reality, with the time of receipt of a light based repreentation of it. So, in effect, his relativity amounts to existence occurring at different times. Which it obviously does not. In other words, he has shifted the time delay which does occur in the receipt of light, depending on spatial position, to the other end of the process, ie existence. He creates the ability to do this by failing to understand how time works. That is, he equates time with what timing devices tell it to be. Whereas the reference for timing is a conceptual constant rate of change to which all devices are synchronised, within the realms of practicality. So his concept of simultaneity in effect creates an xtra layer of time wich does not exist (he called it "common time").
Reality, which is a discrete definitive physically existent sate of whatever comprises it, occurs at a time. In doing so a light based representation of that occurrence is generated. This is received at a later time.
