Are We Living in a Simulation?
Is our world "real" or is it being simulated? We feel as though what we do and experience is genuinely real, but could it all be a kind of realistic illusion? Our technology is advancing so much and doing do so in such an exponentiating way that it appears that indistinguishable virtual worlds and simulations will become a possibility in our future. If so, and if actual conscious simulations are possible could it be that we are a product of some future society's simulation? How could this possibility be instantiated? How could we even attempt to test such an idea? These questions and more are discussed in this episode of Turtles All the Way Down.

The Doomsday Argument
zhlédnutí 797Před měsícem
All things come to an end. Humanity is almost certainly included in this. There will be a Doomsday for our species, but when could it be and how will we end? In this video we discuss an idea that was popularized by the astrophysicist J. Richard Gott, called the Doomsday Argument, in which he predicts when the end will be. His former end time predictions have been eerily and uncannily correct. H...

    Deep down, FoW, if defined operationally in the simplest and perhaps more rigorous way is not a philosophical or scientific concept, but a religious one. Let's first assume, operationally, that events may cause other events. Tracing that chain backwards, from the caused to the cause, leads to infinite regress: there is not an uncaused event with this premise. To resolve the regress, we must postulate that there exist events that happen without a cause. This is pretty much the Aristotelian Prime Mover. The same infinite chain, FWIW, plagues the laws of nature: for every discovery how Nature works, it makes sense to ask, "but why do?" In science, we hit the Big Bang, a barrier impenetrable to information, and all the speculations around it that don't have observable consequences. But let's turn back to the FoW question that becomes, in this distilled framework: do humans possess the ability to cause uncaused events? A physicalist's answer is a firm no: if all there are neural processes and interaction with environment, and these are the causes of any human action. This doesn't at all mean that this causal chain is observable; complexity is a real thing, and this is where the description in terms of tracing which neuron fired and what it caused to another neuron becomes unfeasible and hopeless, but we know that this is possible _in principle,_ that the causal chain always exists, even if unobservable. We can try to throw sort of "true randomness" into the mix, but this year's Turing Award that was given for the proof that the complexity classes P and BPP are the same. This means that there exists a deterministically computable pseudorandom generator that provides enough randomness indistinguishable from true randomness, and adding true randomness won't help make the causal chain truly random, non-deterministic. In other words, if the neuron X fired due to a (true probabilistic, per our best theories) interaction with a stray cosmic ray, there exists an (extrinsic) deterministic computation that may account for this event, too. While this is both fine scientifically and philosophically, it goes against many religious views. For example, in Christianity the source of FoW is the God-given soul. Only God and his beloved children are given FoW; angels, for one, don't. How Mr. Lucifer then managed to act on his own I feign no hypothesis, but I'm sure theologians have a solid resolution for this paradox. With the relaxed definition of the “person presented with a choice, the choice in fact exists and the person is otherwise not encumbered or compelled” there is an issue (or perhaps a non-issue): FoW is a qualium. The person _feels_ they had the freedom, but it's impossible to observe or otherwise prove objectively, or, at the least, unfeasibly hard for any practical purpose. In this sense, FoW exists as, e.g., "redness" does: as a subjective _shared_ percept. I think this view is compatible with the physicalist's explanation. _Objectively_ there is no FoW, but as a subjectively perceived qualium FoW is indeed a thing, as real as the concept of the colour red is. Since a person has no access to the underlying workings of their own brain, FoW is perfectly real and irreducible for them, and their choices are indeed subjectively free. Since we all share this qualium, it's fair to use the concept in secular setting. For example, we can say that a person is responsible for their action, not as a philosophical conclusion, but as a phenomenological and a practical one. One may say that these are two different, albeit compatible conceptualisations of the FoW.

    6:00 This is where the descriptions of space-time seam to go very pear shaped. This appears to paint a geometry of all static 3D space moving along a separate time line. In other words 3D + time (or space + time) separately. I know space-time is a very difficult geometry to think about or visualize :) > 7:28 Objects may exist somewhere out there in the present but we never have any direct awareness of them in the present. All we can ever perceive is the gradient of past time-distance, so it is always the past moments and never now :) > Kool, you did a very well done video. What you have shown here though is the human illusion of the real world rather than the real world outside of the mind. Or to put it another way, this is what the mind thinks it sees so this is the illusion. This human illusion attempts to describe space-time in a Newtonian way although very distorted. The mind wants a stable looking world rather than the blurred external world that we perceive through our eyes. > The actual world beyond the self as is described by relativity (the real universe) is stranger than human fiction, which is why we have difficulty mentally conceptualizing it. I brain and mind just never evolved to see it "as it is" because it is too messy lol

    The concept of time as a psychological side effect of observing change is an intriguing philosophical and scientific question. Here's a deeper look at this idea: Psychological Perspective: From a psychological standpoint, time is indeed a construct that humans use to make sense of the sequence and duration of events. Our perception of time can vary depending on our mental state, attention, and experiences. For instance, time may seem to fly when we're engaged in an enjoyable activity and drag when we're bored or waiting. Philosophical Perspective: Philosophers have long debated the nature of time. Some, like Immanuel Kant, argued that time (and space) are forms of human intuition-ways in which we structure our experiences. According to this view, time does not exist independently of our perception of it. It's a framework we impose on the world to make sense of change and causality. Physical Perspective: In physics, time is treated as a fundamental dimension, similar to space. The theory of relativity shows that time is interwoven with space into a four-dimensional spacetime continuum, where the passage of time can vary relative to the observer’s state of motion or position in a gravitational field. This suggests that time has an objective existence independent of human perception. Neurological Perspective: Neuroscience explores how our brains perceive time. Specific brain regions, such as the prefrontal cortex and basal ganglia, are involved in time perception. Our sense of time can be influenced by neural processes, suggesting that while our perception of time is a product of brain activity, it might not entirely define time itself. In summary, while time as we experience it can be seen as a psychological effect of observing change, there is a broader scientific consensus that time also has an objective aspect independent of our perception. Our subjective experience of time might be a side effect of how our brains process and understand change, but this doesn't negate the possibility of time's existence as a fundamental dimension of the universe.

    Thanks! But I wouldn't call this bending of time a time travel. It's just bending of processes. But in case of the real time travel twins would haven't met each other, being always some time apart, even 1 second. But I don't believe in such time travel either. But I do believe that characters of the movie can travel back and forward in time if viewer rewinds this video cassette. But they wouldn't notice that. With some exception: John Wheeler's Delayed Choice Experiment, where characters are aware of changes, made to the scenario

    I've been saying that "Dark Matter and Dark Energy don't exist" since 2022. We've spent almost a century to find Dark Matter and Dark Energy but still there's no sign of them. No matter what we try, a thing which doesn't exist can't be found. May be it is time to find an Alternative Way to Explain Dark Matter and Dark Energy. 4-D Hypershere model of Universe can easily explain Dark Matter, Dark Energy, Void and even the reason why the measurement values of Expansion Rate are around 70 km/sec-Mpc. Dark Matter, Dark Energy, Gravity, Void and Antigravity, ... all these are same phenomena. They just look different. I agree to the idea that the interaction between mass and space must be explained with quantum mechanics. But that doesn't mean gravity is the QM phenomena. That's because gravity is not a force. Dark Matter, Dark Energy, Gravity, Antigravity, Void... all these are just joint effects of the expansion of the Universe and the curvature of spacetime. Details are given below. Einstein’s theory of General Relativity states that spacetime is curved by the presence of mass. This curvature influences the motion other objects with mass and gives rise to gravitation. Thus, gravity is a result of geometric features in spacetime. However, we also observe gravitational effects - curvature of spacetime - in areas without any detectable mass. This has given rise to the concept of dark matter, which is matter that does not interact in any detectable way with normal matter, except through gravity. So, there is some large quantity of dark matter scattered throughout the universe, which curves spacetime and causes gravitational effects just like normal matter, but we cannot see or detect it with any known method. An alternative theory to the identity of dark matter is proposed - it is not matter at all, but rather an intrinsic curvature of spacetime. In other words, spacetime is not naturally flat. Even in the absence of matter, we observe some inherent curvature of spacetime. So, the question is now - why is spacetime naturally curved? Why is it not flat in the absence of mass? The universe is 4-dimensional, with 3 spatial dimensions and one dimension in time. Rather than consider time as a linear dimension, we can consider it as a radial one. Therefore, rather than describing the universe with a Cartesian coordinate system, we describe it with a 4-dimensional spherical coordinate system - 3 angular coordinates, φ1, φ2, φ3, and one radial coordinate in time, t. We live on the 3-dimensional surface of a 4-dimensional bubble which is expanding radially in time. Thus, the Big Bang represents t=0, the beginning of time. The crucial point is that the expansion of the universe is not homogeneous in all directions. The expansion rate at one point on the bubble’s surface may differ slightly from another point near it. The universe is only roughly spherical in 4 dimensions, the same way that the Earth is only roughly spherical in 3 dimensions. The same way we observe local mountains and valleys on the surface of Earth, we observe local “mountains” and “valleys” on the surface of the universe bubble. The inhomogeneity of the expansion of the universe has given rise to natural curvature of spacetime. This natural curvature causes the phenomenon of “dark matter”. “Valleys” in spacetime pull matter in, similarly to the warping of spacetime of massive objects. So “dark matter” is really “valleys” in spacetime that are expanding slower than the regions surrounding it. These valleys tend to pull matter in and create planets, stars, and galaxies - regions of space with higher-than-average densities of mass. Conversely, “mountains” in spacetime will repel matter away, an “anti-gravitational” effect, which gives rise to cosmic voids in space where we observe no matter. Each point on the surface of the universe bubble traces out a time arrow in 4-dimensional space, perpendicular to the surface. These time arrows are not parallel to each other since the universe is not flat. This causes points to have nonzero relative velocity away from each other. It is generally accepted that the universe is expanding faster than observable energy can explain, and this is expansion is believe to be still accelerating. The “missing” energy required to explain these observations has given rise to the theory of dark energy. The time dilation caused by non-parallel time arrows can be proposed as an explanation for dark energy. Alternatively, dark energy is real energy coming from potential energy gradients caused by non-parallel time arrows. As a sanity check, we can calculate the expansion rate of the universe based on the universe bubble model. Since the radius of the universe bubble is expanding at the speed of light in the time direction, it increases at 1 light second per second. Therefore, the “circumference” of the 3-dimensional surface increases by 2π light seconds per second, or about 1.88*10^6 km/s. This expansion is distributed equally across the 3-dimensional surface, so the actual observed expansion rate is proportional to the distance from the observer. At present, the age of the universe is estimated to be 13.8 billion years, so the radius of the universe bubble is 13.8 billion light years, or about 4233 megaparsecs (3.26 million light years to 1 Mpc). Thus, we can calculate the expansion rate of the universe, per megaparsec from the observer, as: Expansion rate = ((d(circumference))/dt)/radiusofuniverse=(1.88*〖10〗^6 km⁄s)/(2π*4233Mpc)=(1.88*〖10〗^6 km⁄s)/26598Mpc=70.82(km⁄s)/Mpc The popularly accepted empirical expansion rate is 73.5 +/- 2.5 km/s/Mpc, so our calculated value is close. There may be some additional source of expansion (or observed red shift) to make up for the discrepancy. For example, if two adjacent points have some gravitational gradient due to non-parallel time arrows, then light passing through these points will be red-shifted. - Cited from www.academia.edu/82481487/Title_Alternative_Explanation_of_Dark_Matter_and_Dark_Energy

    Down each level of simulation does not necessarily mean lesser and lesser resolution. It only means the speed of light is slower. As consequence of that the 'frame-rate' would drop each simulation down, but only relative to ours. So, since time is relative, there can be a simulation within a simulation that is indistinguishable from the level up or down. For 'simulated' characters like us, everything would seem perfectly normal.

    It could be much better criticism to point out that confidence of prediction is seems to be inversly proportional to the uncerteanty in the time interval. Running it to the extreme one can conclude that we have 100% confidence that humanity will either go extinct tomarrow or stay for billions of years. This ofc checks out, but one can question of the utility of such observation. This being said, not taking it to extremes could be insightful.

    That's interesting. It seems logical that the longer something has lasted, the longer it is likely to continue. Though if in 1989 Gott had recalculated his prediction for the Berlin wall, wouldn't he have been wildly incorrect? It seems like prevailing circumstances should always vastly outweigh the Copernican principle in this argument. That this method will inevitably become less accurate over time and eventually fail spectacularly.

    • @TurtlesWayDown
      @TurtlesWayDown Před měsícem

      If Gott had applied his calculation in 1989 with 95% confidence his predicted minimum end time for the Berlin Wall would have been 0.74 years from then! So, he would indeed still have been correct!! His end time RANGE would just have been wider.

    The fact that we can't know how the distribution differs from uniform does not mean that it doesn't. And we can make estimations of the manner in which it differs. The conditions that led to the arising of the interval can be very different from those that exist at present or will exist to cause its end. Human politics did not advance a great deal during the interval of the Berlin Wall although technology did somewhat change it. For example the Berlin airdrop could not have saved the city 100 years previously. However the powers making decisions were somewhat stable and the financial collapse of one of them was a force that was already familiar. Similarly, the conditions that begin and end Broadway plays had been well established and was not expected to change materialy. Broadway is a limited commodity and somewhat protected from technical innovations.

      I generally agree with your assessment of the potential stability of the conditions of Broadway plays and how the Argument can reliably be used for those. But not so much with your assessment of human civilization or of the fall of the Berlin Wall. What makes both of those different is the enormous amount of unpredictable factors that you would need to analyze to predict the end with any kind of certainty. In both cases, we have very few, if any other, examples to look at. One Berlin Wall, one Homo sapiens specie.

      Well yes and no, but only IF the argument holds AND IF the earliest future date hold it will not be for many thousands of years from now. I'm sure most of what "we hold know and hold dear" will have completely changed by then including, as I mention, our entire species. Possibly a transition? Either way, unfortunately, most people seem to have a greater fear of math than they do of our end.

    There is only one reason to postulate dark energy, to explain the exponential expansion rate of the universe. The expansion was discovered in 1929. It was discovered that the expansion was accelerating in 1998, this is when the concept of dark energy became mainstream. If something accelerates at a constant rate it will get faster and faster. If a ship travels at a constant 1g acceleration rate it would achieve about 95% light speed in 1 year. Electricity is drawn towards potential and the universe as a whole behaves the same way. Electricity comes into our homes because the neutral circuit provides the potential. Electricity is drawn towards grounding rods for the same reason. Physicists in the last century did not postulate dark energy because they understood that the expansion is a fundamental property of the universe. The fact that the expansion is accelerating does not invalidate their reasoning, it's what the known laws of physics would predict. All studies to find dark energy have been fruitless because it doesn't exist. To say there is dark energy is to say there is 5 fundamental forces, there is 4.

    Dear youtuber, congratulations on your subject and the handling of it. If I may suggest something though: please ask yourself why 'music' (if some notes may be called so) is needed in the background. In my opinion 'music behind a voice' is a matter of fashion and - if I may say so - quite a silly one. People who need music in orde to be attracted to listen to the explanation of an interesting and serious subject do not exist. Those who really need a backgrond music are in my view empty-headed (they need the music to fill in a void) and those people are by definition not interested in a serious subject. I found the background 'music' very disconcerting in your - otherwise splendid - video. So, my sincere compliments, but a strong suggestion to let music be music and voice be voice.

      Thanks for the input! However, I find that music in the background adds flavor to the video in the same way that the unneeded visuals do. Without either, the video would lack color. In the same way that many documentaries contain background music and some people seem to focus more with gentle music playing I've found that adding music to these videos gives an added dimension that the videos would otherwise lack. But I would in no way call the curious viewers who enjoy this music "empty headed". I have heard from many intelligent viewers who actually enjoy it. However, I do appreciate your input. Thanks

    The example in the video of the yellow dot moving in 1 then 2 then three dimensions in order to introduce the concept a 4th dimension; time, is fundamentally wrong. Take the example of one dimension, for the yellow dot to move left, right requires time. So in the image of 1 dimensional space time already exists hence it's really 2 dimensions, remove time and the dot cannot move. So we have 1 dimension, a dot that cannot move in any direction other than through time, two dimensions where the dot can move along a line left & right, 3 dimensions left right, forward, back and 4 dimensions all the others and up down. This may be pedantic, but it removes the necessity of trying to illustrate a four dimensional space.

    • @TurtlesWayDown
      @TurtlesWayDown Před 23 dny

      @MillerWright-mb1ob, thank you for the input. I understand the confusion. When I say, for example, that the dot can move left/right, what is meant is that the dot's potential points to lie upon are any of the points along that line, not that it MOVES along the line. If that were the case, then yes, time (another dimension) would then be needed. But it's the POTENTIAL FREEDOM to LIE at any point on that line that makes it 1-dimensional. Likewise, the freedom for the dot to lie at any point within a spacial area (up/down, left/right) is what determines 2-dimensions, etc. When time is added to this spacial framework, it then adds an additional dimension to the existing space dimensions. Time is not explicitly there from the beginning; it needs to be added. To summarize: a spacial line is 1-D, a spacial area is 2-D, a spacial volume is 3-D, and adding in time to make spacetime produces 4-D.

  • @shawns0762

    There is a clear explanation for dark matter. In the 1939 journal "Annals of Mathematics" Einstein wrote - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General Relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light" He was referring to the phenomenon of dilation (sometimes called gamma or y) mass that is dilated is smeared through spacetime relative to an outside observer. A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. Time dilation is just one aspect of dilation, it's not just time that gets dilated. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. Dilation is the original and correct explanation for why we cannot see light from the galactic center. There is no singularity at the center of our galaxy. It can be inferred mathematically that the mass there must be dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. More precisely everywhere you point is equally valid. In other words that mass is all around us. Sound familiar? This is the explanation for the abnormally high rotation rates of stars in spiral galaxies. The "missing mass" is dilated mass. Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. To date, 6 very low mass galaxies including NGC 1052-DF2 and DF4 have been confirmed to show no signs of dark matter. This also explains why all planets and all binary stars have normal rotation rates, not 3 times normal. There was clarity in astronomy before television and movies began to popularize singularities in the 1960's. Einstein is known to have repeatedly said that they cannot exist. Nobody believed in them when he was alive including Plank, Bohr, Schrodinger, Dirac, Heisenberg, Feynman etc.

    Really great video. If Freewill is true then a person who feels that Freewill isn't True, is making a free choice that they have no choice. If Freewill is False (Determined) then a person who feels that Freewill is True, can't help but to feel that way. A paradox (of sorts) for sure! Irrespective of which side one takes, its possible to reflect on the fears & desires leading to the choice. Better to consider the one who sees the paradox. They're "outside" of either options of Freewill. In this way, one can easily detach from the outcome, whether its expected, opposed or unexpected. 🕉️

    I do believe in free will, at least to an extent. Quantum mechanics indicates that things don't exist concretely, but only in states of probability. Meaning that in any given scenario, there always exists at least the slightest chance that things could be different. I would say the same applies to human decisions. Our neurons may fire a certain way, but that's not to say that's the only way they have to. Logically as well, causality is not an inner necessity. One state of affairs does not predicate to a 100% certainty a specific other.

    I am not satisfied with it coming from ‘nothing’ as I define nothing as not even having possibility for something. I am also not satisfied with there always being something because that would suggest an infinite past which raises all kinds of questions. Ultimately my dissatisfaction is caused by my definition of what time and cause is and I’m stuck maybe having to accept against all intuition that I can never understand the true nature of concepts like time or cause

    Nature abhors a vacuum implies there is nature so it's incorrect. The answer seems simple to me. Nothingness would not have anything definable, no time, no possibility, no past, no dimensions. Since we have those things we can conclude that nothingness was simply not possible and there was therefore always 'something'. There no more we can know. End of!

      @eproofI think closest we can get to it is through realizing how nothingness is even created. Concept of lack is a primary quality of nothingness and the more you apply this "lack" to something the closer to nothing it gets. Funnily enough that's why most people suffer too, it's when they get subjected to concept of lack being applied to them. Anyway, if you keep applying that lack to something you indeed may end up with nothing, but since we are trying to define that nothingness from outside we will always percieve it as something undefined. Empty space and something undefined just look exactly same way in my mind, I dunno, that's how it is. And even if you try to put yourself on a place of that nothingness you will not have any experiences at all, because nothingness can't do anything! So yeah, it seems like all evil is based on lack and nothingness.
