Is Reality Real? The Simulation Argument

Is Reality Real? The Simulation Argument


We humans are unable to experience the
true nature of the universe, unfiltered. Our senses and brains can only
process a fraction of the world. So we have to use concepts and tools, to
learn about the true nature of reality Technological progress not only widened
our knowledge about the universe, it also made us aware of unsettling possibilities. In the future, it might become possible
to simulate entire universes. But if this is an option, how can we know
that it’s not already happened? What if we are not creators, but creations? Is it possible that we are not real,
and we don’t even know it? If our current understanding of physics is correct, Then, it’s impossible to simulate the whole universe,
with its trillions and trillions of things. But we don’t actually need to, anyway. We only need enough universe to fool
the inhabitants of our simulation, into thinking that they’re real. Who needs billions of galaxies? We only need the space our
subjects are allowed to explore. The vast universe could just be a flat projection, and they would have no way to know. What about small things like cells or bacteria? We don’t really need them. When you use a microscope, what you
see could be instantly created. Same with atoms the chair you’re sitting
on right now does not need to be simulated with quadrillions of atoms. We just need the outermost layer of it, it might be empty inside, until you
decide to break it open. Your body might feel like it’s filled with bubbly things,
but it might be empty, until you open it. The minimum requirement for our simulation,
is only the consciousness of our virtual humans. Our subjects just need to think the simulation is real. Okay, so are we being simulated? Well, maybe, but there are a few
conditions that need to be met. Obviously, we have no authority over this topic,
so please take everything we say with a grain of salt. Based on a modified version of the original
simulation argument by Nick Bostrom, we have five assumptions for you. If they’re true, you dear viewer are living in a simulation. Assumption one, it’s possible to simulate consciousness Nobody knows what consciousness is. For the sake of argument, let’s assume that you could generate consciousness by simulating a brain. Brains are pretty complex. If you count every interaction between
synapses as one operation, your brain runs at about ten to the power of seventeen, for one hundred million billion operations, per second. Let’s generously assume we need ten
to the power of twenty operations, to simulate one second of human consciousness. But, we don’t want to simulate just one human… We want to simulate all of human history at once,
so we can skip around. Let’s say we want to simulate two hundred billion humans, with an average life span of fifty years. One year has thirty million seconds times fifty years times two hundred billion humans times ten to the power of twenty operations. So we need a computer able to handle million,
trillion, trillion, trillion operations per second. More operations than there are stars
in the observable universe. The computer like this is just impossible. Except, maybe it isn’t. Assumption two, technological progress will not stop anytime soon. If we assume that technological progress continues
in a similar fashion as it has so far, then there might be galaxy spanning civilizations,
with unlimited computer power at some point. Beings on a technology level so advanced, that we
could barely distinguish them from god’s. A computer that can handle a million trillion, trillion, trillion operations is serious business, but there are actually concepts for computers,
which could handle this. The Matrioshka Brain, is the theoretical megastructure, made up of billions of parts orbiting a star,
feeding on its radiation. A computer of this scale, would have enough
power to simulate many thousands, if not millions of humanities, at the same time. Other technologies, like high-end future quantum computers might lower the size drastically, so it might be possible to do this with a structure the size of a large city, or even smaller. But, only if there’s still someone around
to build the computer. Assumption three, advanced civilizations don’t destroy themselves. If there is a point at which all civilizations destroyed themselves, this whole discussion ends here. Looking into space, you’d expect to universe filled,
with millions of alien civilizations, but we see nobody. the reason for this might be, Great Filters. Great Filters are barriers life has to overcome,
like nuclear war, asteroids, climate change or a black hole generator. If life is inherently self-destructive,
then there are no simulations. We explain this in more detail, in our
Fermi Paradox video. Assumption four, super advanced civilizations, want to run simulations. When we speak of posthuman civilizations,
we don’t know what we’re dealing with To think we know what beings as powerful
as gods want, is pretty arrogant. Imagine the smartest ant on earth living
next to an amusement park, It’s curious about what humans are up to,
so you try to explain. Unfortunately, the ant just doesn’t understand. The concept of rollercoasters and standing
in lines and holidays and fun, doesn’t make sense to an ant living an ant life. It’s the same with us and a posthuman being, compared to them, we are ants. Running simulations for fun or science,
might be an absurdly stupid idea to them. But, if they do want to run simulations for whatever reasons and assumptions one, two, three are true too, then the chances are not zero that you
are living inside a simulation. Assumption five, if there are a lot of simulations, you are
probably inside a simulation. if there are simulated civilizations,
It’s likely that there are a lot of them. After all, we assume that post human beings have access to practically unlimited computing power. So if they run simulations, it would be convenient
to run millions or even billions of them. If there are billions of simulated universes, there are probably trillions and trillions of simulated conscious beings. which would mean that the vast majority of all conscious beings that will ever have existed, are simulated. So, for every conscious being made of flesh,
a billion simulated ones exists. Since we have no way of knowing if we are simulated or not, in this case, the chances of you being one
of the nine hundred and ninety nine million nine hundred and ninety nine thousand nine hundred ninety nine simulated ones, are pretty high. So, what you consider reality, might not be real at all You really might be… simulated. All of this is based on a lot of assumptions
that we can’t really test right now So many scientists disagree with
this whole thought experiment. So don’t burn your house down to test
if there will be glitches. If you are simulated, not that much changes for you you might be on a small planet speeding
through eternal nothingness, or a simulation inside a computer. your existence does not become
more or less scary and bizarre. All we can hope to do is try to live good lives,
and have a good time. And hope that if we actually are simulations
in a supercomputer, nobody trips over the power cable. Oh, oh, oh no, I think I just unplugged the simulation But what if that doesn’t matter, what if we are in one right now? What if you are simulated? Jake, over at Vsauce3 is looking into that. Click here to watch his video and

  1. I quite like this theory, it makes a lot of sense about the world we live in. Main example been that when you go out and look around there's so many people that you've never seen before, then you can go to the same place again either the next day or the day after that, at the same time and never see any of the people you saw the first day. Where I live I can see my whole street and I see plenty of people I know passing but I never see any of the neighbors, granted I do see the ones who I know and the ones right next door (The people I know who are there) but I don't see any of the ones from across or further down the street. I know people live in those houses, since I see cars parked on drives, lights on during the night but I've never seen the people. Do we have to need to know who's there for someone to be created, do they need to introduced into your reality in someway or is it just the fact that you've been at work and not seen them go out or they work nights?

    Even though there's probably a good few explanations on why you don't see the same or certain people all the time, like everything else there's always a deeper explanation. I work in a shop so I see a lot of people, I see a lot of regular faces and a lot of new, but I hardly ever see any of the new faces again. Do you have to accept that person? Like get on with them or want to get to know them more?

    You could say all of this is because of the billions of people that are here on earth, but is there billions of people? when you look up to the sky the shape is a dome, is that dome just our simulated viewing perception/allowance? Imagine your in a middle of a open empty field, your looking around as far as you can see, you choose a direction. Now eventually you start to see something, what is it? because it literally could be anything, you might be in need of something to eat so you begin to see a small cafe which is in a random small village. Or you might be walking to find the beach so you soon start to see the sea. I know what I'm getting at and I kind of hope someone else does otherwise I'm just sounding like a complete loon. But basically what I mean is, do our thoughts unknowingly go to some higher power (not a god) that is there to give us what we need or desire?

    I saw someone mentioned The Sims in one of the comments, I'm guessing most of you have played it and it's one of my favorite games. But that is probably a great example for this theory, you can go to the places that you only know about, there's new faces every time a sim dies (computer creations). Your sim calls out when they need something, you give them it or don't if you want to be evil lol, they have whims (wishes) which you can choose to fulfill. So why can't we be Sims with someone controlling us in a way.

    But then you can go on the thought of that we create 'life paths' which come to think of it, I suppose your Sim can too. If you create a random Sim and wait for that Sim to 'voice' it's wants, needs and wishes it is entirely up to you whether or not you give it them. Where as if you create a Sim knowing that you want it to be successful and rich then you've only put it one path. But the random Sim is at the beginning facing three paths, one path for a hard life, the second for a mediocre life and the third for an easy life. But each path still always has a fork in the road, we'll say the Sim has chosen the easy life, the choices in that life still aren't going to be easy, any of the forks in second part of the road can lead you back to the first two options.

    For example you've been born into a family that is wealthy enough to get you a good education to get a job as a computer tech/engineer. You've now go the opportunity to go and apply for a this well paid job, but there's two other options that have been set out to you. You've seen an advert for computer salesman and the other is that you've read about someone earning millions from hacking other computer systems. it's up to you to choose, but is all this still part of a simulated reality. Are we given 3 choices that can easily change the way we live every time we get to an end of a road

    We're told about so many different theories in life some that control the way we live, some are religious, some are beliefs and some are just theories, but all of these are partnered with believing in a higher power, it could be a god, another life form or just energies. Either way all of it thought provoking. Sorry this was a long comment but I enjoy talking about this sort of stuff, it'd be interesting to see what other people think or believe.

  2. And what is the whole point of being simulated? If there is a super computer, this super computer (or simulation generator) would be presumably located and spaced in a real space and time. Being simulated seems to be very far fetch. It seems more likely that reality is what it is.

    Unless there is no computer or anything physical that generates these simulations and the thing is more complex. Which surely it is anyway, and we cannot acces to that knowledge, because is clear that our brain is either capped, or human intelligence is not powerful enough to understand certain conceps… like the one of infinity.

  3. I've thought about if we are simulation quite a lot in the past because of odd/insane coincidences that have happend me sometimes in a row but now I think of zen what I mean by that is reguardless if we are simulated or not it's something to think about but regardless if we are or not life goes on the way it goes on for us even if you knew you were simulated what are you going to do about it we exist because we exist maybe it is for a reason maybe not but things are what they are and are going to be what they are going to be and you have your life to live 🙂

  4. In the words of our good friend Slartibartfast "Perhaps I'm old and tired, but I think that the chances of finding out what's actually going on are so absurdly remote that the only thing to do is to say, "Hang the sense of it," and keep yourself busy. I'd much rather be happy than right any day."

  5. The simplest argument for something being wrong is when errors start to crack up, either within the theory or the simulation. Theory and simulation go hand in hand.
    There are no observed errors. But errors are universal, based on physics and universal laws (entropy and such). Just like aging, as the progressive loss of molecular fidelity. Another all-present accompanying law in this universe. There cannot be a error-free species in this universe. So we can safely put this sim-argument to rest and call it an interesting Movie aka Matrix, that catapulted this argument into the science world in the first place.

  6. 1. I died when he started doing math
    2. If this is a Black Mirror: Bandersnatch shit then I chose the wrong cereal

  7. So why do we assume that, if we exist in a simulation, our simulated reality works anything at all like the “real” reality we have never seen? What’s this whole argument about “what is possible with modern computation” and “what super intelligent life forms might want” when fundamentally, the outside of the simulation could run on completely and utterly different rules than the reality we exist in, functioning by literally none of the laws or equations we’ve grown so much to take for granted. The “real world” needn’t look or act anything like this fake reality we (could hypothetically) inhabit. It doesn’t need photons, or black holes, or protons. Those could all just be things they made up for their simulation, to see what would happen. For that matter, beings in this super reality may not look, act, think in a way we in our little simulated box would ever understand.
    I guess what I’m saying is that, at least now, the simulation hypothesis is an unknowable unknown. Still worth while to talk about though, I appreciate anything that brings philosophers and scientists together

  8. Humans are just another component of a sophisticated '1st person game, produced by the Real self or LIFE.
    The real one playing the game is LIFE i.e. the Real self and NOT the human body.

    DISCOVER and understand the difference between the observe,r (LIFE) and the experience (human body or any other species and its environment.

  9. In case you suffer from anxiety or depersonalization: It's ok. You're real, this is not a simulation. You're a real human, everything around you is real and you have full controll over your body and life.

  10. This mean ur fake my simulator show u in my conscioness only when i open u tube . Plz tell him to simulate me well he is fuck as hell how can he do like this to me

  11. 1. If the 'real world' has speed of light close to infinite (or very large), or have some different law of physic, then their computer can be mucj faster, so it can stimulate all the atom and electron in our universe. I actually think that makes a strong argument: the speed of light is so slow in our universe, particle collapse into wave when it is not being observed, could it both be shortcut to save calculation power?
    2. If there is billions of stimulated world per one real world, the chance od linving in a real world ia very small
    3. Even if the world is stimulated, our experience is real. Is like the happiness and frastration a player get from playing VR game

  12. If we are in simulation, what if we build supercomputer and it runs simulation and something in it makes supercomputer what run a simulation and in it……

    So the first computer must calculate a simulation in simulation in simulation…

  13. Try to respawn
    For what are you waiting
    Just suidside and you will know if we re in simulation

    PLEASE DO NOT SUIDSIDE!!!!

  14. We realistically can never prove this argument correct or incorrect with science. Even if we could prove that it is physically impossible for us to reach that level of computing power, that is in OUR universe. If we are in a simulation, whoever is simulating us may live in a universe with entirely separate limitations and rules.

  15. Video games don't load the entire world you play in, they load pages at a time. The info is only called from storage and placed in queue to be rendered when there is a chance the player might wander into the area. You don't need to render an entire universe, just what the observer sees

  16. The video makes a false assumption: that there is a "real" world to be simulated. How can you "simulate" a brain in a simulation? That would suppose an objective world where brains actually exist, and someone who modeled his fake reality on it. What is the bottom turtle standing on?

  17. It appears the Earth is an incubator for artificial intelligence. Hundreds of millions of years of evolution is leading to information storing, autonomous robotic life. Once the building is created the scaffolding is removed and discarded…

  18. This video is about if future post humans making simulations, but what if the creatures running the simulation made our galaxy up and struggles we face, like conflict and the need for food don't exist. Then they dont need all the right balances to evolve that much as it could be completely different.

    Now your brain has been melted, your welcome👍

  19. If a man accidentally wants to eat hamburger at 3 am in the morning, it is not he wants to eat, but the control request of the matrix to ask him to eat.

  20. The calculation for the amount of computing power needed to simulate humanity makes assumptions that inflate the requirement. There's no reason why we would need to be simulated in real-time or even faster than real-time. We currently have simulations where each generation passes in seconds or minutes, and they're still enormously useful or at least entertaining to observe after the fact. It would still be a lot of computing power compared to what we possess right now but not quite as ridiculous. Several orders of magnitude less.

  21. So if we assume that we’re running on super computers, then can we also assume that sped kids are still running off of windows 7?

  22. although if the simulation is programed for you then if you do burn your house down your only giving into its power?

  23. its not true what jake says, they wouldn't need to process for all humans, just for me.
    all other humans can be simulations too..

  24. You know I keep hear this everywhere "no one knows what consciousness really is" well this came to me one day making playlists on YouTube – "Reality is the physical form of consciousness. The human body is a flesh and bone vehicle for The Spirit, an avatar for consciousness. We are all one in the same. Love always. So in other words YOU are consciousness just like we've always suspected.

  25. Does any of you feal like everything is fake and were stuck in this black dark void.(Also 1 of my classmates said that the whole universe is fake and everything is made out of paper.)

  26. This kind of thought has been bugging me for a few days. Things like "Are we really alive?" "Are we really seeing things?" Etc. Anyone have any idea on how to get it to go away? Anyone ever experienced anything similar?

  27. I feel like the whole argument goes off the rails as soon as you decided that we need to simulate every consciousness. If I am playing a game right now, nothing beyond my immediate surroundings needs to be simulated. So, right now, it could be one non-simulated player consciousness, plus one 3D environment, plus youtube. The computer doesn't need to be able to simulate all of human history, since as far as we can tell, this simulation only uses linear time. Only a handful of NPC consciousnesses would need to be simulated at any time, as beyond that, my ability to differentiate between a "sentient" NPC and an animated 3D model is compromised.

  28. I’ve allways wonderd when I was a kid. Am I the only human and every body else is robots. It always makes me feel alone ;(
