The nature of reality isn’t what you think it is, continued

The Thinker by Rodin

Last November I wrote this post, which suggested (to me anyhow) that what we perceive as reality was anything but this. Since that post, I have been delving more into the subject, which is getting clearer and weirder every day. What’s weirdest about all this learning and research is that the exact sorts of people you would think would be most skeptical about this stuff, like prominent physicists like Brian Greene, are promoting stuff that really sounds outlandish.

Greene is one of a number of physicists who are coming to believe that our reality is basically a hologram. If true, then in some sense we do live in a virtual reality, because a hologram is merely the projected illusion of something that is real and three dimensional, but isn’t.

More specifically, what these physicists are suggesting is that there are many more than the four dimensions (time being a dimension too) that we perceive. This has been accepted wisdom among physicists for decades: that there are 10 or 11 dimensions with the ones we can’t experience being “curled up”. If you think about it though, three of our four dimensions describe space, because space has height, width and depth. Einstein discovered about a hundred years ago that time is relative. The closer you travel to the speed of light, the more time elapses on places not trying to move toward the speed of light. So in some sense, Einstein is suggesting that time is virtual. In fact, Einstein called time an illusion.

The latest thinking among these physicists seems to be that not only is time an illusion, but that space is an illusion too. It turns out this is the simplest explanation for the Schrödinger’s cat paradox, that if a cat could be shrunk to quantum size, then it’s possible for the same cat to be both alive and dead at the same instant. This is because of the non-deterministic nature of the quantum world, where photons can be both particle and wave, depending on whether they are observed or not. If I understand what they are saying correctly, then this only makes sense if space is virtual too.

How to think about this? I imagine a transparent cube through which sunlight streams. It projects a three-dimensional real thing on a surface, but it is a two dimensional entity that we are looking at. If time and space are illusions, as a growing number of physicists are suggesting, then our lives are virtual and space is as virtual as time.

There also seems to be consensus that consciousness is external to all of this. So essentially we are all manipulating a model using consciousness that we call our lives. I imagine me (my consciousness) spending all its time looking at the projection of a cube on a two-dimensional surface. That is my reality, what I call my life, mainly because it’s something I can make some sense of life through interacting with it. I’m so focused on it that I cannot step outside of it. None of us living can, except perhaps some mediums among us. For those of us trapped inside this hologram, it’s as real as it can possibly be. But increasingly we understand that our reality is actually virtual. Perhaps it is better expressed that reality is much more than we can sense.

Many mystics believe in the notion of astral planes, i.e. other realities that the soul (consciousness?) can ascend or descend into outside of the one plane we call life. Many believe that we go into another astral plane after death. Most people believe they only have one life. Those who believe in God generally believe there is only one unique kind of afterlife, in which one size fits all. So most of us can conceive of only two astral planes: this life and the heaven or hell that awaits us in an afterlife. Conceptually there could be many more. Since there are 10 or 11 dimensions and we can only experience four (all of which may be virtual) there could be six or more other planes of existence that our souls/consciousness could inhabit or perhaps already inhabit.

It sounds so bizarre and unreal, particularly given that our reality seems to completely real to us. But this is basically what our best scientists now seem to be telling us. This is not to say they mean that a grand afterlife awaits us in some sort of heavenly cosmos. This is not to say that our traditional notion of God is real either. It does suggest though that real reality, whatever that is, is much grander, interesting and puzzling than we can perceive. If consciousness is apart from what we call reality and it persists after death (we can call it a soul), it does suggest our greater universe is some sort of collective consciousness slowly moving into increasing understanding and complexity as we discover and probe our universe through virtual realities, one of which we call our lives. We may be creating this reality simply by probing and testing its many layers and permutations.

I am reminded of the late author/philosopher Ayn Rand, whose theory of Objectivism I poo-pooed a few times over the years. I still think her theory is bullshit, since it was all about the individual and cared nothing for relationships. But one aspect of her theory was something to the effect that our lives are virtual; so we should feel free to manipulate it to get what we want out of it and don’t worry about the consequences. When we do this, we get the effects we are experiencing today, including the crisis of global climate change. It’s real enough in what we call reality and must be stopped.

Yet on some sort of grander, more cosmic level, she may be right. If these inferences are right, then we are all manipulating models of some sort of virtual world we cannot fully understand or escape, much like a baby puzzles through stacking blocks. Increasingly though, as real as it seems to us stuck in it, our reality is actually virtual. At the very least, it is an imperfect projection of a much grander and more complex reality whose true nature we are slowly uncovering.

The nature of reality isn’t what you think it is

The Thinker by Rodin

The answer to the universe may not be 42 (hat tip to the late Douglas Adams), but its unreality.

That is, it is unreal in the way that most of us think of reality. For example, we perceive that the universe unfolds in a linear fashion, that we exist in corporal form, and that the future cannot influence the past. But that’s not my impression anymore. It’s based on reading a lot about physics and quantum mechanics and more recently from watching a lot of YouTube videos on these topics.

In many ways I believe that we actually are living in the matrix, but not The Matrix presented in three movies of the same name. These movies fancifully depict our lives as hallucinations controlled by machines. If I sound like a raving lunatic, then there are a lot of physicists who agree with me. Physics is revealing certain things about our universe that cannot be explained by the way we think we perceive reality.

It was Albert Einstein who first coined the term space-time. Basically, he discovered that space and time do not exist separately, but they are one thing, whose shape can be perturbed by gravity (which turns out to be a much more mysterious force than space-time.)

On the other end of the spectrum is string theory, the study of the extremely small, which tries to explain just what matter and energy are. We are enmeshed in the fabric of the universe, the physicist Brian Greene wrote in a book of the same name. It was largely his book, which I read back in 2004, which has kept me engaged in this topic since then.

Just as a TV screen consists of pixels, the fabric of space-time appears to have a fundamental unit much, much smaller than an atom. It’s Planck’s constant, which is not a measure of a distance as it is a constant used to express the energy carried by a photon in relation to its frequency. Its value, by the way, is 6.626070150 × 10-34 Joules per second, exactly. The International Standards Organization formally refined its value just five days ago. As best we can tell, it defines the reality we experience, or more specifically an “atom” of space-time itself, something that cannot be further subdivided. This is the stuff that we, but really everything, are made of.

If there is anything apart from the universe, it may be consciousness itself. As best physicists can tell us, time is an illusion, perhaps a mechanism created by consciousness itself to make sense of the universe it is either placed in or observes. Given that space-time exists, but neither space nor time exists as a separate entity, then past and present are permanently linked, and what we perceive as the future influences our past as much as our past influences our future. Who we are is really some subset of space-time. At least in theory it can be played like a recorder, or even played backward.

The more I study quantum physics, the more what appears to be wacky stuff seems to be merging with our “reality”, such as it is. Atheists believe there is no afterlife and there is no soul. It’s a reasonably inference given that most of us don’t see ghosts. If we witness a car running into a brick wall at 100mph, we feel certain its driver is dead. And I won’t argue that that driver is indeed dead, at least as we are bound to perceive him or her in a linear time frame. I think it’s more accurate to say that because we experience the illusion of time, they are dead to us. Yet there they remain, like in indelible ink, caught forever in the matrix of space-time. Our inability to not experience the universe as it actually is, but only linearly, is a deficiency. It’s also an illusion; our shared illusion. Or perhaps more accurately it’s our shared delusion. If souls exist then almost by any definition they travel independent of linear time.

Birth, death and likely living itself are illusions. While ultimately illusions, they are also indelibly real, which makes them hard to figure out. If you are a prisoner traveling in a linear time frame, then they cannot seem to be anything but real. But now physicists are telling us that because space-time is a thing, that our experience of time is indeed an illusion.

I prefer to think of a life as a path, or perhaps a journey, one of an infinite number of paths that can be chosen through space-time. Consciousness itself appears to choose the path we are on. We experience what is before us and react to it as best we can within the limits of our ability to perceive, understand and choose. It may be that we can experience many “lives” through space-time through this thing called consciousness. Hopefully with each reincarnation we do a better job of it.

So everything we experience is both real in a linear sense, yet surreal based on our understanding of the nature of the universe. This is why for me understanding physics is the ultimate head-trip. It describes the nature of reality and what we perceive as reality. It’s clear to me that we are part of a vast and seemingly infinitely complex virtual reality where the perceived and very real (to us) linear parts are very slowly being revealed, thanks to the physicists studying our universe.

Still confused? You have every right to be. But for me this understanding makes more sense the more I study it, and makes me realize certain things. For example, there is no more reason to fear death than birth. We should not fear the escape death might bring us from this experience of linear time that we are trapped in. Death may be the ultimate liberation. Soul may be nothing more than our eternal consciousness as we experience it in a space-time universe.
