Dan,
That is a rather refreshing read. I am also of the opinion our imagination has played fast and loose with the evidence and while the results can be fascinating, they can also be frustrating.
If I may, I would like to add one more anthropocentric assumption to your list. I've made this observation in previous FQXI contests and raised it many times on the forums, but it gets ignored.
Since we exist as mobile individuals, we experience change as a singular sequence of events and so think of time as the present as a point moving along a vector from past to future. Physics further distills this to measures of duration to use in the math. The basic reality though is that it is the changing configuration of what is, that turns future into past. For example, tomorrow becomes yesterday because the world turns, not because the world flows, exists on some fourth dimension from yesterday to tomorrow. Now the reason this is roundly ignored is that it upsets some very important ideas. Basically it means time is similar to temperature, rather than space. Time is to temperature what frequency is to amplitude. It is just that with time, we focus on the rate of change, but haven't discovered a universal measure of this rate. With temperature, we accept the measure as the average of lots of individual amplitudes/velocities, yet that is what time is as well, the overall effect of lots of individual actions. You would think a faster clock would move into the future more rapidly, but the opposite is true. As it ages/burns/processes quicker, it actually recedes into the past faster. Nor do we need determinism or multiworlds, as probability precedes actuality.
Among other things, this undermines the idea of using relativity to explain redshift as an expanding universe. One point I keep trying to make on that topic is that when they say those distant galaxies will eventually disappear, because the light will take too long to reach us, that they are still assuming a constant speed of light across this expanding space, so if there is a stable metric being measured by the speed of light and it is used it as the denominator, then whatever is expanding is the numerator and that's not expanding space, but just an increasing amount of stable space, ie. greater distance. Safe to say, that's not a popular point either. Oh well.
If you have any luck with questioning the establishment, you will have succeeded where I seemed to failed, so good luck!
