    +dsman115276 OR is it random? If you went about generating the videos in a sequence and knew which number of video you were on you'd know about the difference between the video next and before you, etc... which sounds a lot like the principal that mpeg compression is based on..

    Having every video in existence means you have every possible combination of 0's and 1's that forms a video, making it impossible to apply a generic compression algorithm per-video that would result in a net-loss of total data. My comment was specifically about MPEG compression, which is per-video. What you described could work, but it is not a per-video compression algorithm. Without extra data, you could not immediately find and start playing any video from the list. If you wanted to play video 1,000,204 you would have to go through the first 1,000,203 to calculate what it should be. Because of this, the techniques are not equivalent.

    It would not be filled with random data, it would be filled with all data, eventually, so only a few would actually not be compressible. There would be a LOT of redundant data iterating through all possibilities. Regardless, the time is the factor here, not the storage.

You would even find images of that exact banana skin in electron microscopy resolution. There would also be all images of the blueprints needed to build that super computer :-)

    While there are indeed 256^65536 possible combinations of grayscale pixels in a 256x256 matrix, not all of them produce a unique image, since 3/4 of them are just 90, 180 or 270 degrees rotated versions of the same image. And half of the remaining unique images are just a vertically mirrored version. And half of those are just a horizontally mirrored version. Furthermore, if we could somehow predict which percentage of the images are just static noise containing no visually meaningful information, the number of unique images would drop drastically. Adding a noise-cancelling algorithm to detect that image B is essentially the same as image A with a bit of noise on top would narrow down even more. Of course, for any of this to be of any help, the nature of these algorithms would have to be fully predictive so that we would somehow know which images to skip before creating them. Question: what is the propability, that given these modifications, we could build a supercomputer which would be capable of producing all the possible visually meaningful images in our universe in less amount of time it has existed?

To give you an idea how many zeros would be in the equivalent in base 10: Every 0 you wrote after the "." adds 10^82 zeros in base 10. ;) So if you add your number to itself and put 1 atom in a new universe, you would've created 138 universerses before you reach 1 (and 1 in b10 is eqaul to 1 bUniverse)

Experience and Gold stop at 65535 (but 0 is counted as well, giving us 65536). It was like magic to my 8-year-old mind that I could understand why my game was so limited (especially since my dad, who at that time was one of the smartest men in the world to me, akin to Einstein) couldn't understand why the numbers stopped. It's not often that an 8-year old gets to teach his dad something.

    Wouldn't a femtohertz be 10^-15 Hz instead of 10^15 Hz? A hertz is a cycle per second so a femtohertz would be 0.000 000 000 000 001 cycles per second which is absurd. A Petahertz would be more correct.

    Now here is a follow-on question... how much prison time would you get if found guilty of copyright violation for every copyrighted image which you produced by iterating through all of the images? I'd also ask how many other crimes you would be guilty of from generating every possible otherwise illegal image (illegal pornography and the like)... but that would probably not be calculable in any reasonable way. For copyright, you could probably estimate it reasonably well. Would you be in prison for longer than the age of the universe thus far? WRT the number existing before the universe... unlikely. The universes fundamental structure is probabilistic. The natural numbers are not really natural, they're an artifact of the human experience of the universe. Things look definite and discrete, but those are only emergent properties of the interactions of those probabilistic particle/waves. Additionally, the idea of 'before the universe' inherently makes no sense. In order for the word "before" to have meaning, time must exist and proceed in an ordered fashion. Spacetime was created at the Big Bang, and is not causally connected to anything 'before'. Mathematics is amazingly useful for understanding some parts of our universe (it doesn't seem to like nonlinear differential equations with trillions of variables though and unfortunately that's what is necessary to model almost anything real accurately) but it's completely unrelated to it. WHY it works so well is a complete mystery. A pretty nifty one if you ask me.

    The number of images containing sensible objects is thankfully a lot smaller. But still, it makes you appreciate how insane the task of pattern recognition actually is. Say you are training a computer to only distinguish cats from dogs. While a lot smaller than the set of all possible images, the set of images showing all possible cats and dogs is still absolutely astronomical. And you are trying to find a function that maps this insanely large set to the correct answers. When you look at the problem in this way it is kind of amazing how well these algorithms do.

He makes a lot of gross simplifications and unrealistic assumptions based on the maximum KZread file size (128 GB), and considers all permutations of bits in a file of said size. In reality, only certain permutations of bits in a 128 GB file will result in a valid file of a certain file type. Video file types will indicate where the video is and where the audio is, but none of his calculations about KZread videos take this into account.

    Pro Tip: When superimposing white text on a black background (which it looks like you pre-composed), change your blend mode to screen. This will remove the stark black background from the pre-composed image and have the text appear on top of your existing background for a much cleaner look. Conversely, black text on a white background can be superimposed nicely via the multiply blend mode.

    Good thing we're creating a vast number of new universes in order to keep track of our actual computations-- because we're gonna need them. There aren't enough atoms in the universe to build a memory that would store all possible KZread videos, even if every atom could be used as a binary (two-state) indicator.

    So, in theory, if someone makes this super computer. I could find a sex scene with my crush in there?

    Yes. But at that point, wouldn't it be easier to simply create the sex scene by individually shading each pixel?

    I love coming back to this video every now and again just to have my mind blown by the pure scale of it all. What's insane is that if you set the supercomputer running at one image a femtosecond, you could also, say set your wealth to accumulate at the same rate of one penny (USD) per femtosecond. That way you have the same amount of pennies as images. How long would it take for you to become the richest man on the planet? Well, since a femtosecond is 1/10^15 and Bezos' net worth in pennies is around 10^13, you are literally 100 times richer than the richest man on the planet after just one second of your supercomputer running. In fact if you were to blink (roughly 0.1 seconds) you would still be a trillionaire and therefore around 10 times richer than Bezos. Every second. 100 Bezoses. And it takes 29 million universes one atom every single femtosecond to complete the KZread task. It's unbelievable.

    I think that's underestimating the mind blown-ness, it's more accurate to say it takes a whole universe per atom in the universe per atom in the universe per atom in the universe per atom in the universe (repeat writing this out 29 million times). Once you ran the first 13.8 billion years of KZread videos, one video every femtosecond, only then would you put one atom in the 2nd universe, and after running another 13.8 billion years, you could put another atom in, so you'd have to run the whole universe an entire universe of atoms number of times to fill the 2nd universe, but that lets you put only 1 atom in the 3rd universe. You then have to run 13.8 billion years to start another 1st atom in the 2nd universe, another 13.8 billion years to put the 2nd atom in the 2nd universe and so on and refill the 2nd universe with atoms all over again just to put the 2nd atom in the 3rd universe.......Just like you have to run KZread videos the whole universe to put 1 atom in the 2nd universe, so must you refill the whole 2nd universe for each atom you put in the 3rd. Once the 3rd universe fills up with atoms, then you can place an atom in the 4th universe, and it begins again: Run KZread videos 13.8 billion years -> 1 atom in 2nd universe -> whole universe of atoms in 2nd universe -> 1 atom in 3rd universe -> whole universe of atoms in 3rd universe -> 1 atom in 4th universe -> whole universe of atoms in 4th universe -> 1 atom in 5th universe.....and so on for 29 million universes. In other words, for each level of universe, you have to redo the level below it a universe of atoms number of times going back every level to the beginning just to add 1 atom.
