The issue that has kept me up for the greatest number of nights is, of course, time and its relationship to entropy. Entropy APPEARS to create the arrow of time; I use the aging and death example as the most obvious result of entropy and our clearest link to something we call ‘time’ passing. However, if Lorenzo Maccone’s theory is true, the processes of increasing and decreasing entropy happen all of the time; in other words, events ‘undo’ themselves on a regular basis. The way we store memory, however, excludes the possibility of recalling any event or circumstance where entropy decreased. Therefore, due to our selective memory processes, we only see ourselves as ‘falling apart’ due to the laws of thermodynamics, leading to the rusting of our physical bodies and our eventual decline. However, the opposite processes could be happening–there are scenarios where we are growing younger–if you define younger as a state of lower entropy in the cells of our body–yet, our brain could not record those instances as memories due to the fact that memory only records events correlated to higher entropy, events which appear to have ‘results’ or represent change.
The idea that there are entire realities where our scenarios are radically different from the one that we are currently experiencing seems hard to accept, but it resolves the entropy problem without attempting to define something that for all intents and purposes, has no independent existence (time). Entropy is the only process that appears to create an ‘arrow’ of time, since the physical processes involved move predictably towards dissolution (from highly ordered to disordered, or towards uniformity in a closed space, resulting in the breakdown of the physical organism in the case of old age). If, however, we don’t remember the instances when entropy decreased, we would only be able to perceive events and processes in the same way, i.e., as ‘moving’ forward and causality based. Event ‘A’ appears to cause event ‘B’, but only because we have correlated higher entropy states with causal change. In reality, we are selectively perceiving events and creating meaning that is not inherent in those events at all.
The following is a quote by Robert Lanza is his most recent article debunking the notion that quantum gravity is responsible for the “arrow of time” perception:
“As the direction of the arrow of time is associated with the increase of von Neumann entropy, the observer A is simply unable to recall behavior of the subsystem A associated with the decrease of its von Newmann entropy in time. In other words, if the physical processes representing “probing the future” are possible to physically happen, and our observer is capable to detect them, she will not be able to store the memory about such processes. Once the quantum trajectory returns to the starting point (“present”), any memory about observer’s excursion to the future is erased. It thus becomes clear that the discussion of the emergence of time (and physics of decoherence in general) demands somewhat stronger involvement of an observer than usually accepted in literature.”
Memory depends on certain ideas and assumptions: first and foremost, that the ‘past’, ‘present’, and ‘future’ somehow exist as separate categories of spacetime, and that memory can only store (somehow) past events and circumstances, not future ones. To remember a future event would imply that the human brain is capable of ‘storing’ it somehow, and we are not wired to recall or be aware of events that are not tied to quantum decoherence (quantum decoherence brings quantum systems into a classical state). Does a decrease in entropy make quantum decoherence impossible? If quantum decoherence creates or makes possible memory storage, then yes; no memories can form if no wave functions collapse to create the necessary traces of ‘past’ events. In other words, events that appear to move backwards would reduce entropy, and therefore leave no trace of ever having happened–therefore, no memory could form of an event undoing itself. If the new memory theories are valid, and the brain is a quantum-based organism, then decoherence would create memories and would therefore be dependent upon entropy increasing. Decoherence could not occur (and thus no memories created) if entropy were to decrease. The quantum state would remain in flux; the wave functions would never collapse.
You and I, as observers, collapse wave functions and bring reality into focus. This assumes, of course, that consciousness plays a fundamental role in creating our sense of reality, time, and causality. If indeed our observations–or our interaction–with a quantum-based reality creates what we experience and remember, then it’s equally clear that we don’t remember most of what happens to us. Any event or process that involves a decrease in entropy would never make it into our memory banks–how much of our lives have we forgotten?
What follows is pure speculation on my part, and it’s quite possible that my status as layperson will lead me astray in terms of the science; so if a reader knows that my ideas are not supported by physics or any other field of the sciences, please let me know. We only perceive our lives to be moving forward due to the association we have created between entropy and events we associate with it. For example, if I have a new wrinkle on my face, I assume that the wrinkle is directly related to time passing, since I don’t remember seeing it before. I also associate the wrinkle with decay, since I know that collagen breaks down ‘over time’, a direct result of entropy: things fall apart, they don’t come back together. My wrinkle, then, is evidence for time, because I am comparing two events: my face without the wrinkle, and my face with the wrinkle. I project into the future the reality of more wrinkles and more collagen collapse, because that’s the pattern I am observing. I compare, sequence, and make assumptions about the future, because aging is tied to the appearance of the wrinkle (more wrinkles appear when entropy increases). I remember my face without wrinkles: the image of myself with a smooth face is burned into my brain as a reality that ‘happened’.
If we make no assumptions about the process that I have described, it looks different. If I had no memory of my face without wrinkles, then I would have no reaction to the image in the mirror. It would signify nothing. Meaning is created via memory. If there is no memory, there is no change and no time, as there is nothing to compare our current experience of reality with. What is memory? A trace that an experience leaves behind in the brain (and this is not a given; nobody really knows where memories are ‘stored’) that can be accessed in the present moment every time we activate the memory. Actually, we’re really only remembering the last time we remembered, creating an infinite regress whereby the original ‘event’ is totally lost (or existing somewhere else in the present moment). The only memories that can be successfully ‘stored’ and recalled are those which involve the ‘falling apart’ or ‘cooling off’ or ‘disorganizing’ processes of entropy. When we throw the ball at our friend, hit his head, witness him howl in pain, and suffer punishment, we are witnessing entropy in action: it creates the illusion of cause and effect, energy output and heat loss, action and reaction, first this happened and then that was the result. This is how we create stories and narratives and assign meaning to events (never throw a ball at someone’s face or you’ll get into trouble). Because there was a consequence to the action, it appears that time is involved. Action A led to Result B, and that can only happen where time moves forward.
And yet. All we have here is a series of events. Is it possible that multiple scenarios played out that day? Perhaps I was punished before I threw the ball. Perhaps the injury to my friend happened at the same time I threw the ball. Perhaps I never threw the ball and nothing happened; or my friend caught the ball, and no injury resulted. Maybe the whole scene played out in reverse. I would only remember the scenario that resulted from the Second Law of Thermodynamics. All other scenarios would vanish into the ether, or perhaps play out in the infamous multiverse.
Infinite scenarios played out that day, but the fact that I only remember one of them is required to live a human life. We are, in part, biological creatures who must obey the natural laws of the universe. If we could remember all the scenarios that were created that day, we would be paralyzed by infinity. We could not organize our lives, could not function in material reality, and would never learn that there are natural consequences of our actions. The moral imperative would vanish if there were no cause and effect. If I can commit murder and that murder is only a crime in one of the multiple scenarios that split off into infinite dimensions, there would be no “I”, no sense of self, to experience the horror of taking someone’s life. Any action of mine would instantly become trivial, since it would result in multiple outcomes, none of which I would take any responsibility for.
The main point, then, is that the sense of self depends on the illusion of time and causality. At the level of ultimate reality, there is no time, no space (check out Julian Barbour’s THE END OF TIME), no causality, no actions resulting in consequences. Events shift around and reconfigure in infinite patterns. It is consciousness that organizes and arranges events into time and space. We create the past, move through the present, and anticipate an illusory future. We can all agree that the future doesn’t exist; yet, we don’t see how we’ve experienced an equally illusory past. The only evidence of the past shows up in the present moment as traces of various kinds. Those traces can only point to themselves; we have to grant the traces (memories, documents, photos, records) existential meaning and authority in the now, via a consensus community. You cannot point to something called the past. You can only point to the traces of it in the present moment. You call your own mental processes the ‘past’ because you ‘remember’ the events in one, specific way. Our sense of reality is based on comparison to others’ sense of ‘what happened,’ on a created continuity between events and experiences.
Many would argue that it is the broad, ontological agreement among us that proves the reality of time. I would argue that consensus creates reality itself based on a shared understanding that time exists and our lives follow a sequence and a chronology. Our human brains filter, reduce, manage, and organize information in very similar ways; it’s what they’re designed to do. But we shouldn’t confuse our physiology with reality itself. We only understand the world in a certain way during normal, ‘ordinary’ waking consciousness; however, there are multiple states of consciousness where our brains stop creating the world in the particular way they do when operating in consensus mode. For 6-8 hours a day, we are in an entirely different state of consciousness where all the rules regarding time, causality, space, and reality are suspended completely. We don’t consider that to be abnormal or extraordinary. We simply don’t know how to navigate and comprehend altered states of consciousness. We don’t get the ‘rules’, and we don’t know how to share that state with others, so we decide that anything that happens, anything that we experience in these ‘other’ states of consciousness is somehow false, unreal, and tells us nothing about the how the universe might actually work unbound from our sense organs.
We confuse our sense organs with reality itself. It’s a basic mistake. The universe is far more complex and creative than our brains allow it to be. I believe that there are ways to expand our knowledge and understand of reality that extend beyond the information that we can glean during our normal, waking hours. Just what that might look like or how it might happen will be the subject of future posts . . .
So stay tuned, dear readers, if there are any left at this point!!
