I argue in this work http://www.sciforums.com/showthread...ure-unless-they-are-active-in-a-present-frame that there is no such thing as past or future, because all there ever exists is ''snapshots'' of present frames of time. If everything is stuck in the present, then how do we sense a time, why do we think it runs forwards with a specific ''flow'' and ''direction?'' Newtons flow of time doesn't exist in modern physics and there is no true direction of time in the cosmological arrow, there is only a measure of entropy, or change if you like. What we have is a sophisticated memory which records one instant of time to another. To derive that, we can say that the duration of consciousness experience a ''flux'' into the future is \(t_0 + \Delta t = t_2\) That is... \(t_0\) (the present time) added with a small dilation \(\Delta t\) takes the observer into the future frame \(t_2\).. Distinguishing \(t_2\) from \(t_1\) (the past) as it is impossible for asymptoptic local observers in quantum mechanics, but somehow not inside our brain. Fred Wolf asked a question, is the past complimentary to the future? If it is, then we might be able to model the mind into physics somehow by recognizing there to be some ''special line'' which separates the past from the future, even if it is an illusion, can be modeled as the complimentary conjugate \(t_0 - \Delta t = t_1\) We can't reverse time, but the logic of the math says that a dilation taken away from the present moment is hypothetically a ''frame back'' in the past. This won't have drastic implications for physics, unless physics is able to prove that the observer somehow is unique in the sense that consciousness is required for an understanding of time itself and what it actually means. The best understanding of time, is the psychological arrow which is regulated by the brain, these circadian rhythms actually account for our experiencing any kind of time, so this is an indication that a complex mind, one that can record vast amounts of information has to have a sophisticated long-scale memory which gives us a broader experience of these collections of \(t\) as we regulate it in a certain ensemble. This ensemble probably isn't a mistake, it's probably the only way the mind can censor out static reality and bring about the sense of changes around us. Perhaps, this could yet let the observer play a new role, an interesting role at the very least as a sub-system in the universe.
