Do we live in a computer simulation

This made my head hurt... Do we live in a computer simulation[^]
For a thorough discussion of this question, read James P. Hogan: Realtime Interrupt. That guy knows his stuff, far better than the majority of SF writers. True enough: He spent a few years as an engineer in the computer industry before going full time as an author. Yet, very few computer guys are able to write books that can stand up against time as well as his stories do. Another one of my favorites of his is "The two faces of tomorrow", one of his very first books, written in 1979: I reread it about a year ago, 32 years after its publication, and I think the fundamental issues he rises are still valid today. Fun, great action. Who would think that a computer program could generate "great action"... "Realtime Interrupt" is far from new, published 1995, but the same applies: The questions raised are just as relevant today as they were 17 years ago. And Hogan's storytelling has developed: The novel manages to give most readers a creepy feeling, a nervousness, causing us to always take a second look - around the corner, under the carpets, inside that locker - to check if they have remembered to include that part in the simulation...

There's some circumstantial evidence we do live in a simulation: The universe behaves differently when we observe it, than when we don't. For example, when shooting a single subatomic particle at two slits, it appears to go through BOTH of them simultaneously. (The evidence is that the "single" particles form an interference pattern that you'd expect from two particles or waves.) But when you place sensors nearby to observe this curious phenomenon, the interference pattern STOPS, as if our simulation is providing more detail because we're looking at it. The analogy is to computer graphics/virtual reality, where objects that are currently in the distance aren't rendered in as much detail as objects we're observing nearby. Objects not in the viewport aren't even rendered, for efficiency.

Oh, the interference can certainly be observed with suitable sensors. Besides: You reference to subatomic particles implicitly assumes (in your following comments) that subatomic particles and, say, a lead bullet shot from a rifle, are so similar phenomena that you can describe them in the same way. If a lead bullet cannot pass through two slits at once, nor can a photon. But a photon (or other subatomic particle is a different animal. In some respects, it is more like a wave. I guess you don't see a problem with a wave breaking through two openings in you wall at the same time. In some types of observations it is like a wave, in other types of observations it is more like a particle. But it is neither. It shares properties with both waves and articles, but not all properties of either. Actually, even large scale observations can be strongy affected by (un)suitable sensors. Say that you want to sense waves on water breaking through a slit in the wall, and your sensor is a pressure sensitive plate that you place directly in front fo the slit. Then the half-circle wave pattern behind the slit would disappear, due to your sensor. At the subatomic level it can be shown that any sensor would disturb the phenomenon you want to observe. This is fairly well understood by those working in the field; it is no sort of magic. Regarding rendering: As mentioned in another post, I recommend James P. Hogan: "Realtime Interrupt". It directly addresses the question discussed in this thread.

"But when you place sensors nearby to observe this curious phenomenon, the interference pattern STOPS, as if our simulation is providing more detail because we're looking at it." Or it could be that when the sensors are in place to observe the phenomenon, those sensors exert enough change in the environment to cause the phenomenon to stop. This can be inferred due to the trajectory of a bullet when shot. A bullet's trajectory will change depending on wind currents. More wind, verses less wind. The influence of the wind on the bullet would be comparable to the influence of the sensor's magnetism on the particle. Even if there is the most minimal amount, it remains substantial enough to affect the trajectory of the sub atomic particle. Are you suggesting that scientists with their years of education and experience have not considered this to be the cause of the difference in outcomes? Scott A. Tovey
"Or it could be that when the sensors are in place to observe the phenomenon, those sensors exert enough change in the environment to cause the phenomenon to stop." Possibly. I don't know what the reason is, but I offered one possible explanation that's consistent with a computer-simulated universe. "Are you suggesting that scientists with their years of education and experience have not considered this to be the cause of the difference in outcomes?" I'm assuming they must have considered it, but I'll have to look into it further. (I dabble in physics, but it's not my field.)

True story, told to me by a previous supervisor. A couple of computer techs were working on a computer in an office trying to figure out just why it would not turn on. A couple of hours went by and the chief secretary walked in to see how the progress was going. As she turned to leave she noticed something and asked: "Is this supposed to be plugged in?" The computer techs looked over where she was pointing and became angry at the sight of the computer's power cord laying on the floor. Plugged it in and turned the computer on. End of true story. :) Yes, I am suggesting that despite their years of experience and education, they may be fixated at finding a complex solution when in fact the answer is quite simple. It happens. I've done it many times. Why? Because experience tends to find the solution in the complex and so we become conditioned to look for the complex solution before we eliminate the simple solutions as the answer. I've sat and worked on code for hours trying to solve a particular problem with a particular set of steps until I got so frustrated I decided to walk down and get a soda. On the way to the machine I realized that the code I was using was never going to do what I was trying to get it to do. I had to rewrite the whole function. I call these little incidences. I.L.S => Infinite Loop Syndrome. How does this happen? When I'm absolutely sure that I'm doing something the correct way, I don't consider whether the code is appropriate for the task and not liking to be defeated by the tree I'm chopping down, I have a tendency to get focused on solving the problem that particular way. So what's wrong with that? What's wrong is that not even a senior master programmer would be able to get the code to solve the given problem. The code is just blatantly simply wrong. Scott A. Tovey

"On the way to the machine I realized that the code I was using was never going to do what I was trying to get it to do." Yup. I can't count the number of times I'd been working on a problem unsuccessfully for hours, then on a bathroom break, the solution hit me. There may be a simple reason for the single-particle/interference-pattern phenomenon, but I suspect this "simple" reason may appear counterintuitive to us because objects at the subatomic level are fundamentally different than what we're used to.

The thought has actually never crossed my mind (Except when watching 'The Matrix', that is), that we are part of a simulation. More likely in my opinion is that everything exists as the dream of a deity like creature with extreme multiple personality disorder. Moments of 'Dejavu' are the being's mind's way of trying to accept actions or circumstances that don't fit the personality. Probably a COBOL programmer. I know I've felt that way before. :-D

It sounds the same to me, but I'll give you that.

Are you sure it not understanding the rationalization for suffering? Or perhaps it more along the lines of not understanding the rationalization for not helping those who are suffering?
jschell wrote:
Yes you have summerized one argument that attempts to explain suffering away under one specific type of deity where one is also claiming compassion (where compassion must equate to lack of suffering.)
How can one explain away what is clearly before their very eyes? How does one explain away suffering? To explain something away is to imply that it does not exist. I did not in any way attempt to explain away suffering or imply that it does not exist. Nor did I equate compassion to being the lack of suffering. If you reread my post, you will understand that I stated that suffering does in deed exist, and the lack of compassion is the lack of people who do not or have not suffered, refusing to help those who are suffering. Helping those who suffer does not negate the suffering, in many cases it only lightens the burdens. In some cases, such as unemployment and poverty, helping an individual find a job or giving the individual a job, will eliminate the suffering of unemployment. However, it will not necessarily eliminate the harm that the suffering has caused. Especially if the individual has gone through an extensive period of unemployment and has been discriminated against by lying employers claiming who claim the individual can no longer do what he or she once did. That is some major psychological warfare and is not remedied by simply providing employment. Then there are the ones who go hungry and suffer loss of health for no other reason than the fact that employers refuse to hire them. Again, an act of war. There may not be a combat unit laying siege to those people and preventing them from receiving food, these people however, are no less under siege. War is being waged against them as if they raised up arms against the government, even though they have broken no laws. Guilty by the declaration of guilt. No arrest, no crime committed. Ju

I can only suppose you missed the part where I said "...where one is also claiming compassion" or perhaps you did not understand it. Rephrasing...if one is claiming the deity is compassionate (and knowable) and if one attempts to explain suffering then one must attempt a rationalization that includes the compassion of the deity.

I am rather certain that it as odds with the understanding of most judeo christian beliefs and most definitely is at odds with any standard philosophical musings about the same. If one imagines a deity that encompasses the universe a human mind cannot encompass it.

Sounds like spiritual nonsensical rhetoric used to disguise an argument that is the same as a more clear philosophical one that has existed for thousands of years. Or worse rhetoric used to disguise that one doesn't understand how easy it is to explain the unknowable nature of a deity.

Due to Fridays events, I chose to wait until today to respond as I did not wish to state something that would be misconstrued in regards to all those families who lost children, and loved ones. The point of my use of man's relationship with women as an analogy was clearly missed. So I'll skip the analogies and state plain and simple. Unless a man works at it, he will never know the woman he spends his life with. Likewise, no one can know God if they are not willing to put some effort into it. And just as you cannot enter into a relationship with a woman without fulfilling some of the expectations she has regarding the relationship, a man cannot begin to know and understand God without doing so on His terms. Every so often I decide to look up a word just to make sure it means what I think it means and quite often, I find that what I think the word means is not included in the definition of the word. So I decided to looked up the word compassion. com·pas·sion a feeling of deep sympathy and sorrow for another who is stricken by misfortune, accompanied by a strong desire to alleviate the suffering. Please note that the definition says nothing about actually alleviating the suffering, just a strong desire to alleviate the suffering. In the Gospels, Jesus teaches a parable of a farmer who sows good seed in his field. At night, an enemy comes along and sows tares into his field(a noxious weed). Rather than going through and ripping out the tares and accidentally destroy good crop, the farmer chooses to wait until the harvest when both are easily distinguished and separated. The point here is that the farmer could easily remove the tares at the cost of some crop, but chooses to not loose any of the good crop. As illogical as it may sound, God could remove suffering, but the cost of doing so is to loose some of those who would otherwise be in good standing with Him. He deems such a cost to be to high. Having compassion is not the elimination of suffering, it's suffering with those who suffer.

Most of the time our syntax is correct, but our logic is always flawed. God must have used the old waterfall development methodology. :^)

Sounds like a spaghetti monster, but that sentence is phrased kind of backward. The idea is that IF we are likely to become posthuman, and run simulations of ourselves, then the humans in those simulations are likely to do the same, and so on, until there is a large number of simulations. In that case, the probability of us being the very first simulators is very small, so we are almost certainly living in one of the simulations. So I think the point of the above statement is that you can't believe we are likely to become posthumans capable of simulating ourselves, unless you also believe we are almost certainly in a simulation. Not saying there is any evidence either way, but neither is the quoted statement. It's not really a speghetti monster, more of a statement of the constraints of belief in such a speghetti monster.
I am thinking the core assumption of these scientists is wrong: Assuming that a highly developed race has the ability to start such a simulation, what would be the point of including the simulation itself, recursively? It would just be an endless recursion, and each recursion step would be less accurate due to resource constraints. I can think of some use to run a simulation of the past, but why run a simulation of the present? Moreover, at the point the simulants... err, the simulated scientists set up the simulated simulation, they should be able to notice the restrictions of the simulation apply to their own universe. At which point the simulation cannot probably remain accurate, simply because at least some of those scientists will be more interested in contacting their "creators". The only reason for the "creators" to keep a simulation running beyond that point would be that they're not actually running simulation of their own universe - more likely they're just running a game (maybe "The Sims CLXXII"?) :cool:
