Richard Linter November 4, 2018 at 10:56 pm Reply There is something wonky about drawing ultimate conclusions about the cosmos when our instrumental probes are still ten orders of magnitude away from the Planck scale. The paper referred to at 10:19 is well worth reading, even so. But it's a review article. There are others, more cautious in approach. One accessible viewpoint would be a transcription of a keynote speech by Feynman (Int. J. Theor. Phys. 21, 467 (1982)) on "Simulating Physics with Computers ". A reason is that Feynman established some ground rules early on. You can find a transcription at http://doc.cat-v.org/feynman/simulating-physics/simulating-physics-with-computers.pdf. That is easily the most readable early discussion; and there he explains a deep link with "No hidden variables" and the EPR paradox. Feynman especially compares and contrasts quantum computing with the same issues (simulating probabilistic physics) as on a "Universal" computer, remarks that a quantum computer is "not a Turing machine, but a machine of a different kind", and ends with cautionary tales about his fights with Fredkin, about reaching too far with theory. He ends:"All these things suggest that it's really true, somehow, that the physical world is representable in a discretized way, because every time you get into a bind like [discretizing a continuum], you discover that the experiment does just what's necessary to escape the trouble that would come if the electric field went to zero, or you'd never be able to see a star beyond a certain distance, because the field would have gotten below the number of digits that your world can carry." I can just imagine him yelling that, in his broad Brooklyn lecture voice. Can we encourage readers to look at other authors, who covered similar ground very much earlier than 2001? Lloyd's review is a good effort. But it cites earlier, fuller expositions including his own published in "Nature". Remarkably, the reference (number two of 43) is quite bare, quoting no volume of page number, just the year published (2000). (At a guess, Lloyd's cited article is "Ultimate physical limits to computation", volume 406, pages 1047 through 1054, which in turn cites the pantheon of computational physics, notably Landauer, Feynman, and Deutsch.) Finally, it behooves us to be careful of drawing quasi-religious conclusions from the admittedly fascinating discussion presented. For one thing, PBS does a good job of explaining how a universe can be simulated by a computer it contains. (Spoiler: can do it by taking extra time). But discussing the number of operations per second of a computer simulating a universe in real time, one which must surely sit outside that universe, is a little off – even if I can think of workarounds, such as changes in photon state as a clock-tick. batmanbutbetter November 13, 2018 at 3:23 am Reply Are we talking RAM or hard drive? nosuchthing8 November 17, 2018 at 2:18 pm Reply Thumbs down.

For all the information that does "exist" in our universe can be reinterpreted to information that doesn't exist. To this point, it is not only the number of combinations held within the informations, but also the number of interpretations from it. So it could very well be infinite.

Gregory Manning January 28, 2019 at 3:40 pm Reply Okay, I propose that he was right in assuming he's under estimating the amount of information from each Plank unit in approaching this with classic bits. The reason the final number seems to small is your starting point is wrong. Replace bits with qubits per Plank unit. A qubit is capable of storing more than one state at a time while a bit is a classical binary expression of a single variable with only two options, on or off. Qubits are much better suited to information storage in a quantum field, though what the "limit" would be is likely defined by one of the physics constants. As just a short sighted example, if the qubit storing data for each plank length had a queue depth of 32 bits in parallel, your final calculation makes a monster jump up, making the universe far too large to store in a device smaller than it without using a deeper qubit depth than reality itself on the storage media. The limit on whether the universe's entire information catalogue could be stored on a device smaller than the universe would then hinge on superior quantum storage density than reality itself offers currently. The requirement then is to create qubits with a depth greater than whatever depth of qubit the universe itself offers naturally in order to make such media. Such a "hyper-dense" qubit may not even be possible. Państwo Piesto January 30, 2019 at 10:43 pm Reply Why did you assume that the smallest 3d planck is cube shaped?

Diego Pazos February 18, 2019 at 8:35 am Reply I don't get how they intend to represent the whole deal with 1 bit per Planck volume.

How come that the radius of the universe is 47 billion light years whereas the age of the universe is only 14 billion years. Did the universe expand faster than light can travel? But nothing travels faster than light? Thanks in advance Lance Tschirhart February 25, 2019 at 5:29 am Reply The radius of the universe should be should be 14 billion or so plus some more perhaps, from dark energy acceleration. Is dark energy the only cause of this huge discrepancy between our universe and a stably expanding one? I always thought that the CMB was only 13.8 billion light years away, not 47, and my world made sense, and I felt safe, like in my own safe little fact-womb. Perhaps the radius is 47 billion light years according to our calculations, which show the background is more than three times as far away as it appears(?)

I doubt "the Milky Way's black has as much entropy and hidden information as the rest of the universe" seeing as there are other black holes out there at the center of other galaxies.

In a hologram, each unit contains information about light from every point; each unit encapsulates the whole. Is consciousness thus intrinsic to the entire universe? Or in other words, shouldn't there be a certain level of emergence no matter the scale? Something else that leads me to this question is the fact that our universe is fractal, meaning, from the macrocosm to the microcosm, self-similar patterns repeat themselves. Take the golden ratio for instance, its found within the spiral arms of galaxies all the way down to the petals of flowers and even ourselves. In short, with this in mind, is it too far-fetched to say that our consciousness is a holographic temporal fractal and can be found on every scale of the universe? Perhaps I'm letting my existentialism get the best of me, open-minded feedback appreciated. SmartK8 April 11, 2019 at 8:26 pm Reply If you associate information with IT or computers than it would seem like Universe is a simulation.

As long as you don't require the shape be convex, there is no bound on the surface area of a shape you can fit inside a cube, sphere, etc. Does the surface area argument apply only to convex shapes, or does the resolution lie elsewhere? Or is it really true that one volume can contain more information than another volume which contains it? Fabrizio Giordano July 6, 2019 at 10:48 am Reply So the answer is right in front of our eyes, nothing say that we can't live in a black hole, in fact, the space is expanding faster then light, so we know for sure there's something, in a rotating black hole, if the rotation matches the spin and the forces I guess everything inside is moving slower, and the changes of the spin and rotation of black holes changes the inicial state of the universe inside the black hole, the one we can not see, I think if we go the center of the universe we could experience strong gravitation warps, or I'm wrong and is been proved already that we don't live in a black hole, I don't know, is just what I think Alex July 9, 2019 at 12:49 am Reply I usually watch these kind of videos to release some of the entropy in my head, but at the end of the video I feel like a black hole. 😝 Richard Deese July 14, 2019 at 8:57 pm Reply I saw a commercial yesterday.

(one could call it a Beckenstein-shell) _ note 1: i have a hunch that info-maxed-out spacetime voxels _ can ONLY be stacked in 2D arrangements and not in 3D packings. _ note 2: i suspect information can not travel through an info-maxed-out voxel. a maxed out spacetime voxel needs an adjacent not-maxed-out voxel to keep it linked to existence/the cosmos. – RECYCLED ( BLACK HOLE ) ENERGY HYPOTHESIS dark energy, the energy that drives cosmic expansion is in fact recycled information that is deleted from black holes at the moment of their creation and growth in size (the black shells). after deletion, the information returns to the cosmos in random locations in the shape of fresh new spacetime. thus the overall AMOUNT of information in the cosmos remains constant.

Suffice to simulate information flow through a someone’s “mind”. Everything else can be computed on an on demand basis. In the meantime let it all be in an uncertain state, let’s call it a superposition.
