In discussing frequency response and bandwidth with Einstein, and as a result of a PM from MadIce, I have hit upon some interesting insights that I thought were worth sharing and (if anyone is interested) discussing.
We often hear that "time is a local (relative) phenomenon", or alternately expressed in lay terms as "time is not real" or "time is an invention of man's mind". Scientifically, this is better expressed in terms of time variation with respect to an observer's reference frame as one's velocity begins to approach that of light (thanks to Einstein). But let's really hone in on the issue here: Time requires an observer or, at a minimum, an observation (measurement). This is due to the fact (as I have stated here often) that the metric of Time is characterized by Matter in Motion. If we, as human beings, were not capable of conscious observation, then we would have no means to conceive of "tense" and, in essence, there would be no such thing as our own, local Time.
With the understanding of the requirement for an observer/observation for Time to become "real", we can further investigate why it is that our ability to observe results in the perception of Time as a linear flow, which we interpret as tense. It all boils down to the concept of frequency response of any observer (or observation hardware), and the observer's limited bandwidth.
The best example of this that will help us understand the nature of local Time (as well as what happens if we attempt to transcend our limited view of Time) is the human sense of sight and our ability to sense a narrow band of the electromagnetic spectrum which we call "visible light". By definition, the bandwidth of the human optical sensory system (eye) is limited to the range of 4.3E14 through 7.5E14 Hertz. It is our ability to make visual observations within this operational frequency band that permits us to order the arrow of Time in accordance with these observations.
It is interesting to conjecture about what would happen to our local perception of Time/tense if we were afforded an infinite bandwidth for sensing the entire electromagnetic spectrum. Let's begin by thinking about what might result from simply expanding our sensing bandwidth beyond the visible light spectrum. Currently, because we cannot see beyond this spectrum, we perceive "outer space" to be empty. Yet we know that space is far from empty, as there are radio waves, cosmic waves, and the like propagating all around us. We simply do not see them because they are outside the operational bandwidth of our eyes. Thus we only order our timelines via the Matter that we can perceive to be in Motion around us. If all of a sudden our visual bandwith was made much wider, such that we could visually detect radio waves, cosmic waves, and the like, wouldn't it have a distinct effect on how we perceive Time (Matter in Motion)? I believe it would. I believe it would give us a much finer resolution of perceived Time because there would be a great deal more simultaneous events occurring around us.
Example: We track the time of day by the passage of the sun from horizon, to overhead, to the other horizon. The discrete positions of the sun as it progresses on its transit of the sky give us a certain tolerance for knowing what time it is. By adding more visible Matter in Motion represented by other electromagnetic phenomenon outside the visible light spectrum, we would have more feedback, more information, from which to make a more discriminatory measurement of Time. It could very well result in a perception of Time moving slower than we currently perceive with our existing visual light bandwidth.
If we apply a little bit of calculus to this problem, and examine what happens at the limit as the sensing bandwidth approaches infinity, the logical conclusion is that TIME WOULD STOP, or another way of saying it would be that Time would cease to exist in that observer's local frame of reference. Interestingly enough, this would directly correspond to Transient001's discussions of the Prime Temporal Point. Any observer with infinite sensing bandwith would not discriminate "past" from "future". All Time for that observer would exist within a single observation.
Wild stuff... Any thoughts or comments?
