    The planck length and planck constant are both ultimate computational constraints on physical interactions, with planck length being the smallest meaningful scale, planck time being the smallest meaningful interval (universal framerate), and plancks constant being both combined to tell us about limits to how fast things can compute at the smallest meaningful distance steps of interaction, and ultimate bounds on how much energy we can put into physical computing.

    The word “meaningful” does a lot of heavy lifting there. What does that mean? Do things which exceed the limit become meaningless? Because I was thinking, since we cannot know the future, as best as we could ever do is to approach infinitely close to the future, but never actually pass it*, because it hasn’t happened yet, and thus is unknowable. Like an event horizon. Not only on the macroscopic, but also microscopic scale there seems to be a limit beyond which all inquiry, or escape as it were, becomes possible as a matter of some sort of gravitational geometry.

    Again, I want to stress I have no idea, I’m just an enthusiast so sorry if my musings make no sense, I appreciate a lot you taking your time with me and all of us to talk about this, so I’m just happy to be here.

    Thanks for the cool graphics, they make sense!

    *Just like you can’t escape the singularity once you’re bound. Same same but different! A transistor flipping a bit is a calculation.

    A transistor flipping a bit is a calculation.

    It is an “action”, a passage of time, an action in time, quantified somehow, a single unit of the passage of time? Like a photon is both a wave and a particle but neither and both at the same time? So how does one measure that, and more importantly, what goes on in the immeasurable space meanwhile? Particles jumping in between space and time and shit, everywhere, nowhere. The Universe is a very naughty place and has a gambling problem.

    is a calculation

    The word “is”, is a problematic word. Are things only calculations? Who is doing the calculating? What is calculating what? Calculation implies intention, as far as I am concerned. Or inevitability! Some form of mechanical causal chain that just plays out the movements it is predestined to play out and free will is an illusion which it very well might be, I don’t know where I was quite going with this, we should start a podcast I’m sure we’d be great.

    The neurons in my brain firing to select the next word in this sentence sequence from the probabilistic sea of all things I could possibly say, is a calculation.

    I hear ya!

    Pascals triangle directly governs the amount of microstates a finite computational phase space can access as well as the distribution of order and entropy within that phase space.

    I see!

    Each microstate is statistically probability weighted based on its entropy/order. Entropy is a kind of ‘information-theoretic weight’ property that affects actualization probability of that microstate based on location in pascals triangle

    The future can be predicted? To what degree of certainty? Can it be fully predicted?

    the planck length or at a time interval smaller than planck time will cost more energy than the universe allows in one area

    Fair enuf.

    Sounds kind of like an event horizon. Like. You know, if you want to travel faster than light, you need infinite energy to get there. Or something like that. I get the feeling that the Universe is simultaneously the largest and the smallest thing that exists. Kind of a weird position to be in when you think about it, because the Universe is infinitely vast, but it is also infinitely small, down to quarks, bosons, or strings, or whatever. Like it’s, well, expanding, elastically, in both directions at once. Would you agree?

    actualized bit of distinction

    Mhm. Mmyes. Quite so, quite so.

    Our ability to talk about abstractions is tied to how complex they are to abstract about/model in our mind.

    Cool.

    The cool thing is language evolves as our understanding does so we can convey novel new concepts or perspectives that didn’t exist before.

    Is it enough to express it all? What would that mean? If we knew all the laws, would we be able to perfectly predict the future?

    Its impossible to ever know whats beyond this horizon boundary. similarly,black hole event horizons share this property of not being able to know about the future state of objects that fall inside.

    Similarly. That’s exactly what I was thinking. I mean, we can see a resolution of within 300000 years of the creation of the Universe, or something like that. That too, becomes a sort of an event horizon. I’m not saying this is the case, but it kind of rhymes if we were within some sort of bubble on “the other side” of a supernova resulting in a black hole. I mean, even by our own physics, matter is energy, and energy cannot be destroyed only transformed. So, it could be that, in my mind, the Big Bang was an “inverted supernova/black hole” event. I think someone called it a “white hole”. But again, I’m just completely speculating, but it’s super interesting to me as someone who just has a passion for learning and understanding and trying to figure out things myself based on the tremendous works of all the giants upon whose shoulders I stand and squint at the horizon!

    Edit:

    A cosmologist would say they are different phenomenon but from an information-theoretic perspective these are fundamentally indistinguishable Riemann manifolds that share a very unique property.

    I don’t know exactly what you just said, but I understood PERFECTLY what you just said.

    Edit{2}:

    They are geometric physically realized instances of uncomputability which is a direct analog of godelian incompleteness and turing undecidability within the universes computational phase space.

    I am amazed that I understand what you are saying.

    Edit{3}:

    The universe is a finite computational system with finite state system representation capacity of about 10^122 microstates according to beckenstein bounds and Planck constant. If an area of spacetime exceeds this amount of potential microstates to represent it gets quarantined in a black hole singularity so the whole system doesnt freeze up trying to compute the uncomputable.

    Did you write this, genuinely? It is pure poetry such that even Samurai would go “hhhOooOOooo!”.

    And it is so interesting, because, what you are talking about sounds a lot like computational constraints of the medium performing the computation. We know there are limits in the Universe. There is a hard limit on the types of information we can and cannot reach. Only adds fuel to the fire for hypotheses such as the holographic Universe, or simulation theory. But for me, personally, I believe that at some point our own language breaks down because it isn’t quite adapted to dealing with these types of questions, as is again in some sense reminiscent of both Godel and quantum mechanics, if you would allow the stretch. It is undeterminability that is the key, the “event horizon” of knowledge as it were.

    You are absolutely right, and it is obviously not that simple, I have some tentative leads which, based on recent discoveries such as just this apparent “axle” of the Universe, could actually mean something significant. I am aware the hypothesis has been proposed previously, I believe in the 80’s, and it was not taken seriously, and as I read the news about this new discovery, to me it struck me as a smoking gun moment- if there is an axle or spin to the Universe itself, that would be a sort of tell tale sign of a black hole seen from a certain perspective (outside of the Universe, which poses a problem, but not really, because we know about dimensions, so it could in my mind hypothetically itself be explained even if I am not sure what that would look like if you catch my drift).

    To me, as a layman, and just fanatic lover of space (and time), I just pareidolia my way into hypotheses, and more often than not there’s some reason to it. So that’s my ground. I wrote quite a bit about it and did some research into various theories surrounding it, and there has been a lot of renewed interest in this Black Hole hypothesis ever since this discovery was made because apparently I was not alone in drawing the same possible conclusions.

    Thank you so much for your detailed answer, I will go through it now and read what you wrote and what you posted, to get a better understanding, because obviously I am nowhere near qualified to make such bold statements as I have done. But did anyway.

  • Not gonna lie, go on a flight from France to South America on an Air France plane in 1954 would have been pretty sick. 100% they would have been smoking on those flights, back in my day even in the 80’s airplane armrests still had those foldable ashtrays built in.

    I mean have you ever wondered why there is a dedicated “NO SMOKING” sign next to the “SEATBELTS ON” sign, even though everyone knows you can’t do that? It’s funny to imagine what it would have been back then, it must have been fucking intolerable with the god damned smoke filling up the cabin, you’d be hotboxing carbon monoxide for hours on the flight.

    But you were also “kind of” ok fucking the stewardesses (fully consensually), and there was an open bar, and probably fewer seats at passengers, so you had better legroom. Probably the food was also top notch.
