Editing, for me, is problem solving. The Holographic Principle is such a heady idea that it demands visual content that’s easy to follow and comprehend. Hopefully I was able to achieve that here. One of the things that always helps me to understand complex ideas is the language of popular culture. It’s something we all share, and in that way it can serve to ground abstractions in common mental anchors. Hence the use of McConnaughey. Who is more of a mental anchor these days than McConnaughey?!
If you want to learn more about the holographic principle, I highly recommend watching this lecture by Leonard Susskind:

[@Nerdwriter1]

Ha! Honored by the comparison.

[@giovannilacala8003]

+Nerdwriter1 subscribed man. It's still difficult to comprehend, but from what I got from the video, black holes aren't places, but the lack of a place. They are "places" in the universe where the fabric of space/time just cease to exist, like a hole in a trampoline. So when someone enters that whole from an outside observer, they never fall in, they simply stay on the event horizon in a 2d fashion. That's some beautiful stuff to think about

[@JamaicaSugar]

+Giovanni Lacala But the event horizon would keep pulling you towards the center, eventually down to the singularity, after an incomprehensibly long time, and at the singularity is the birthing of a 2 dimensional universe. From what I understand our 3D universe was birthed from the matter in a 4D black hole's singularity.

[@HungerGamesFan88]

At least you can't feel yourself stretching and crushing to death. Gotta be nice.

[@circuitboardsushi]

The singularity doesn't exist. Nothing beyond the event horizon exist, though you wouldn't know that if you fell in. As far as everyone else is concerned you can never make it beyond the event horizon. From your perspective you fell in; but actually you are still on the surface; but with all the info that makes you, you, encoded in a 2D on the event horizon.

[@Hecatonicosachoron]

A few corrections are necessary: (1) 'Erasing files' is not why "laptops get hot". The amount of heat released from changing the state of the memory is miniscule compared to, say, the resistive heating of the wires which have no influence any particular state of the memory or the processor. (2) The Bekenstein entropy solved a different paradox than the now-famous "black hole information paradox". These are two completely different ideas (the former was older, concerned entirely classical general relativity and its apparent inconsistencies with thermodynamics and kicked off the field of black hole thermodynamics; the second is an inconsistency with the unitarity of quantum mechanics). They should not be confused. (3) The holographic principle, even if true, does not necessitate that a lower-dimensional hologram is a physical reality. The holographic principle is a duality between two descriptions, which are deemed to be mathematically equivalent. But, for example, we could say that coin flips are mathematically equivalent to flicking light switches, but that does not imply that switches are coins. Sure, the correspondence is not just between the physical states in two theories, but between more developed mathematical structures. But, still, the physical implications are the same. Even if true, holography does not imply that there must exist a physical boundary for the universe. And it is still quite speculative.

[@jesselee2549]

[@vinzer72frie]

You're wrong on number 3 it is absolutely the other way around, numbers show that these lower and higher dimensions are physical quite the contrary to speculation, people are who refuse to believe it is real until observed

Just deleting things on your computer only unallocates the space on the disk where that information is. That's why data recovery works if the space hasn't been overwritten

[@Kevalalalalalalalala]

Curio Fawkstrawt then how do you explain my pc getting so hot?!?!?!??!

[@EveBatStudios]

I'm not sure why you think that has something to do with unallocating disk space as opposed to overwriting data. It's not like it throws the data into an incinerator on your computer.

[@icemd24]

Curio Fawkstrawt xDDDDDD

[@bassbrothaUG]

+Kevalalalalalalalala Your PC gets hot because certain components of your computer need to heat up to function. Your processor, memory and even things like your disk drive require electricity to work. In order to work properly, some of this electricity needs to be "resisted", which essentially means certain components of your computer need to convert electricity into heat. This is why when you run high demanding programs (video games, math intensive software) your computer gets really hot as opposed to idling. This video was great but the fact that deleted data turns into heat is completely false. Curio is right in this case, it becomes "un-allocated"; marked as deleted through certain code and "available" to overwrite on your computer. This is why it is REAL important to wipe your hard drive when you throw out your old computers, not just delete everything. However, since the writer of this video is from a non-technical background, I still think that he did an excellent job with his video and he should strive to extend his own and audiences base of knowledge. I still learned tons of new things and greatly enjoyed it. Cheers

[@RialVestro]

It sounds like you're saying that things going threw a black hole aren't actually being ripped apart, it just appears that they are from outside of the black hole. In other words we could actually travel safely threw black holes. However we have tried to send camera threw them before and were never able to recover anything. That's how we know they are being ripped apart. Though the idea that there's nothing on the other side is a complete assumption on our part. I think they do go some where but because there's no safe way to travel threw them everything on the other side would be ripped apart beyond any recognition. I don't think anything could be completely destroyed even by a black hole though as already pointed out there's no way to prove it one way or another.

[@tnethacker]

Love this man, addicted to all your vids. Especially liked your Understanding Arthouse videos - I used your analysis of Snow piercer to defend that film to friends who think it's too literal. Have you seen "The Congress" yet? I'd love to see an Understanding Arthouse about that film.

[@SloeElvis]

correction: The information you erase from a computer *is* gone. It doesn't "turn into heat". You simply tell your reliable storage (HDD, or SSD nowadays) that the bits that stored that file are now free to be written by anything else. They'll eventually get replaced by other information. So yes, the memory that stores that information does not change, or go away. But information is abstract enough that it *can* disappear into nothingness.

[@RoboBoddicker]

Yes and no. He's talking about information in the physics sense, which is a much more fundamental concept than just the digital information stored in your computer. You're right that a deleted file doesn't just immediately turn into heat. But overwriting the file requires a distinct change in energy in the system, and that energy is then transferred to the surrounding atoms in the computer and in the air. But if you had precise knowledge and control of all those small energy changes in the drive and in the surrounding atoms, then you could theoretically recreate the deleted data. That's what he means by information being conserved. The physical information about that particular state of your computer can't be fundamentally destroyed - like energy, it can only disperse and change forms. The difference with black holes is that the Hawking radiation particles don't seem to have any link to the matter that fell into the black hole. So unlike those deleted files, there doesn't seem to be any way to recreate the infalling matter from the Hawking radiation.

[@moreoddthanduck]

For a few years, I've read science articles reporting on the "universe as a hologram" and despite reading these, and even going after some of the primary content, I never actually understood what a hologram meant in this context. Your video helped me to understand this concept for the first time. Thank you!

[@smithmwk]

Perhaps I'm missing the point, but what exactly do you mean by the word "information"? I get that the interplay between energy and mass can never be destroyed, but my concept of "information" is a specific organization of matter, conveying an idea that is only relevant in the context of being understood by someone. In this sense, when you delete that file and the bits are randomized, some electric charge being dissipated as heat, the information is very much destroyed. This is in the same sense that if I threw my computer into the sun, the dispersed atoms would no longer constitute a computer.

[@rorybyrne86]

+Mackenzie Smith If I understand it correctly, it's referencing "physical information" and more specifically "information theory". Information carried by a wave function or quantum wave. In a very basic sense the information carried by the wave/s would describe the particles that made up your laptop as still existing and the arrangement that they currently exist in. They may not exist as a "computer" but they still exist. Sean Carroll described it like this: “Imagine that … you throw a book onto an open fire. Later, you worry that you might have been a bit hasty, and you want to get the book back. Too bad, it’s already been burnt into ashes. But the laws of physics tell us that all the information contained in the book is still available in principle, no matter how hard it might be to reconstruct in practice. The burning book evolved into a very particular arrangement of ashes and light and heat; if we could exactly capture the complete microstate of the universe after the fire, we could theoretically run the clock backwards and figure out whether the book that had burned was this one or [another]. That’s very theoretical , because the entropy increased by a large amount along the way, but in principle it could happen.”

[@dixonbuttes]

Yes Rory is correct in his explanation. This is how it's explained by Leonard himself as well

[@012stactic]

Hi Mackenzie I believe this is very much related to entropy which comes under second law of thermodynamics, for example in the case of information say the word document that you created, had organised particles that enabled into exist for example the Kbs or mb, when you delete this the information simply changes form from an organised particles such as your kb or mb to a more disorganised which the memory released from your pc in form of free space. this is alot similar to an ice cube and a glass of water. A glass of water has high entropy due to molecues being in a state of dissary and disorganised where as an ice cube will have frozen molecues which is low in entropy once the ice cube melts it will increase in entropy, and therefore from organised becomes disorganised. Hope this forms a better understanding of information paradox

[@yggysquirrel2446]

umm but isnt the "information" of every single particle infinite? as in it can have an infinite amount of positions in a given space??

[@NoR3m0rs3]

Information = matter

[@abraxamovic]

2:20 Nope, he was not thrown into a black hole. Instead, he was drawn towards the black hole, Gargantua, after separating from Amelia and the Endurance. He never actually enters the black hole; as he is in an interminable freefall, he is getting closer and closer to the event horizon, and the forces become so great that he is forced to eject from his Ranger, which instantly crushes. In that moment, he is moved by the Fifth Dimension Humans (FDHs) into their Tesseract. This is a rescue action. “How did he start communicating with his own daughter in the past when he was in the black hole?” Having been moved from the black hole into the Tesseract, Cooper is presented with an endless array of 3-dimensional “snapshots” of Murph’s past as it relates to Cooper. Notice, there are no snapshots of Murph in the current time, only as she is a young girl prior to Cooper’s departure. As Cooper views these snapshots, he realizes that he can affect things in them by using the one thing common to all of them - gravity (which transcends all dimensions). So, pressing on books that were teetering, he’s able to cause them to fall, which alerts Murph’s notice. Later, by altering how sand falls, he’s able to give the coordinates to the NASA facility. Last, he gets the inspired idea to convey the quantum data to Murph through the one thing that is dynamic across time and gravity, and that Murph would be sure to keep - the wristwatch. The FDHs could not communicate with Murph (or humanity in that time) because they could not identify an object that they could affect and that someone (Murph) would keep across time. Because of Cooper and Murph’s relationship - built on love - that wristwatch was (almost) guaranteed to be in front of Murph; and, it is a dynamic object, in that it is in motion, and can have its inner works manipulated by gravity in a way that Murph would understand - Morse code. It is very important to point out, though, this is happening inside the Tesseract; not, I repeat, not in the black hole _The comment is actually based on Max Steiner’s reply from Quora on the question _*_In “Interstellar,” how did Cooper survive after being thrown into a black hole? How did he end up in the hospital bed? How did he start communicating with his own daughter in the past when he was in the black hole?_*

[@futurehistory2110]

I think it's an information reality. The 'hologram' may be how our brains make sense of that reality (i.e. the answer is right in front of our brain).

[@willsimerly3006]

yup

[@radicalaceshasbrin5802]

When you delete a file, the pointer that allows you to access the file is no longer stored, the data is still there. You will over time re use this memory as you use your computer for other things. Data isn't tangible, it's simply the ability to or not to travel down a certain path. Information in that sense can be destroyed because it simply refers to how you are using 0s and 1s. Just because you change an 8 bit value to all 0s doesn't mean you lost memory, it means you changed it.

[@stevoofd]

3:05, if you look slightly cross eyed in the bottom left direction, you will see a knight appear on the left, and if you then look at the entire picture, a knight on the right as well, and what I assume is a flying angel in the middle. Normally paper stereograms don’t work for me, but this one really pops out, and if you move the screen those 3 figures will appear to parallax against the background wall. Very entertaining!

Okay, first of all laptops don't get hot because information that is deleted is turning into heat. Ugh... Secondly, anyone who knows how a hard drive works knows that files don't actually disappear when deleted, but are eventually "written over" by new files. Even completely "wiping" a hard drive only smooths out the small, sequential transitions in the magnetization of the platters that "created" the data in the first place.

[@Mutantcy1992]

In the stereogram at 3:10, I see two knights and a sort of ghostly woman. The knight on the left holds his sword downward while the knight on the right is holding it up and to the right. The woman ghost thing is in the middle, and has long hair, but no real body and appears to be floating with tattered cloth hanging in the air below her, slightly to the right. I saw it by crossing my eyes until the image resolved.

When you said we would see them get shredded in the black hole that's not true. We would actually see them get closer and closer more slowly until they seem to stop. This is due to time distortion.

[@LeoMRogers]

Black holes dont radiate 'superhot energy', unless they are extremely small. The temperature of the (admittedly, super-massive) black hole at the center of this galaxy is about 1.5 *10^-14 kelvin. This is why black holes haven't been observed directly (afaik), their radiation is far lower than the background radiation of the universe.

[@mohamedqasem]

The reason Mcconaughey didn't die in the black hole is because of the type of black hole he entered. According to Kip Thorne in his book, "The Science of Interstellar", there are three types of singularities. He called one of them, "Gentle Singularity." It's the reason Mcconaughey stayed alive, and didn't get spaghettified. Of course, all of this is speculative. Thanks for the video. Wonderful work.

[@NOCTURNUSFILM]

Hey, I always knew that all the other people are just holograms. And now you're telling me that I'm one, too...?

[@maeva5257]

I love how you made it graphic! To complete this theory : The reason why we don't see the world as a hologram is because inside of a black hole, the quanta of space (gravitational field) does not form the dense webs that we call space. We can't see things where there is no space. (It doesn't mean that nothing happens though.) So entropy (basically the evolution of the movements of a system) visually translates only where there are gravitational particles (quanta or granular space). They appear to us as if they were on the same "layer", but only because of the great areas between them that separate them from each other. It's like superimposing multiple canvas which would have many holes in them and of which the remaining areas would be painted. It would look just like the painting in this video. Like a hologram. But anywhere aside from the inside of a black hole, space webs are fully formed. We are surrounded by a myriad of holograms, superimposed in every possible way, covering every point in the space. And this appears to us as a 3D image. The reason why their superposition seems so smooth to the human eye is only because we fail to distinguish every fragment of the evolution of entropy at its microscopic scale. And that's where the notion of time comes from. Time is only a blurred perception of the nature of the world. So basically, we are a myriad of holograms.

Having spent three hours at the library doing research, I decided to head home for lunch. On Jan. 17, 2000, at 2 pm, while crossing a river bridge in Burswood (Perth, Australia) on my bicycle, I observed a velvet-textured beige pearl covering the sun. Within the entity, there were containers in the shape of elongated, seven-pointed Koch snowflake fractal crystals immersed in a white misty light travelling in a ten o'clock direction. I later considered that the light flashes on the inner space of the crystals might be of a binary language conversion pertaining to the senses of all mortals, that is, a holographic universe.

[@matthewcoon1022]

The moon is a cold light holographic projector. The cold projection rushing towards the heat projection is what causes tides to happen. To view the different layers of the fractaled holographic projection you can use the same vision needed for stereograms/ stereoscopic illusions. That ability is not only for novelty.

Think of the surface being the fixed points on a grid. At tangible locations you can return coordinates and retrieve the information that is being held at that point. The space between the the integral positions on the grid can be considered the void. In this fractured space, you only have potential information that can only exist in an imaginary plane. Also, when you "delete" a file on your hard drive, the space it occupies on the disk doesn't actually get erased. Simply, the operating system is now given permission to write over that sector of disk with new information.

There's an interesting connection here. McConaughey's character in True Detective (Rustin Cohle), at one point gaveva long speech about the M-Brane theory which sounds a lot like some of the concepts discussed here. Specifically he talked about the fact that a 4th dimensional being would view our world as flat(similar to how we perceive cartoons) In the same year, he starred in a film which showcased these concepts.

[@bejewelednarcissist]

No castle in the stereogram. There's one man on the left with a sword pointing towards the floor and on the right are two men armed with rifles. In the middle floats a ghost like figure like only the cloak floats, but theres no actual body inside. You can even see the hollow space of the cloak through an opening of the cloak's hood and through its opened sleeves. It's only those 4 figures floating above the background. It's probably the most detailed stereogram I have ever seen.

[@chell_1.]

The heat that computers produce is from the processor units in the most part, information on a computer is just an arrangement of magnetic patterns in the disk. I believe information (or at least the text file) can be destroyed, given that it exists only as a pattern on the disk, and the disk before and after the file is the same.

[@MAJ-Pronounce]

I'm glad that Susskind and physicists are looking into this now. Many years ago I learned that while there is no discernible pattern to PI in base 10, but that doesn't mean PI doesn't have a pattern. If you calculate PI using base 2 or base 16 there is a sequential pattern. This concept lead me to wonder about the perception of reality. Maybe we're understanding is leading us to see no discernible patterns because we're using the wrong "base" as our physical reference. This is where Susskind's hypothesis interests me. Maybe our eyes are taking in 2D holographic information and our brains are processing (filling in the information, reversing entropy) into 3D. I know this seems beyond reason, but it's like when Einstein was asked about being a scientist he said, "what does a fish know of water". That is how this 2D to 3D processing is to us. It is so common (i.e. the fabric of existence) that it is undetectable.

[@TheKurama9]

Awesome video! The "alright alright alright" part made my day. You got a new subscriber =)

[@nh7tr]

I'd love if you did one on the simulation hypothesis. This was an amazing video.

[@rodrigopacheco12]

I have no idea where you saw a castle in that picture, but I did manage to see two knights and a ghost

[@VultRoos]

I love how this video was presented.it explains things really well.thanks for the vids!

[@aadapt-forwardpositivemome471]

this is a really great explanation thank you ! I'd like to share this on my Facebook group to generate some discussion

[@thetruthfromthefuture]

I miss your original background music, like the one that plays in this video. I still love your new stuff, but I thoroughly enjoyed your older ones. They contained your heart, soul, and felt like, no matter what the subject matter, that you would always tie it into our human morality and on what genuinely makes the human species beautiful (even though we can be so very ugly at times). I digress, basically I would love if you utilized your old bg music in some way shape or form in your newer videos. :)

[@blackorchids]

Amazing video as always, you are so good at explaining these finer topics to a laymen like myself :P, I've still never been able to do one of those sterogram things though :/

[@Nerdwriter1]

It's very hard for me as well. My eyes hurt by the end of it.

[@MAuric10bal]

It´s not easy, but it´s amazing once you see it. It´s like seeing beyond the image itself, at first, until you find the right, so to speak, focus. Keep trying, it's beautiful.

[@borial01]

The event horizon of black holes do not radiate "super hot energy" they are actually the coldest place in the universe. Empty space is 3 degrees Kelvin due to cosmic background radiation. Black holes radiate more energy the smaller they are, but in order to have a Hawking temperature larger than 2.7 K (and be able to evaporate), a black hole would need a mass less than the Moon. Such a black hole would have a diameter of less than a tenth of a millimeter. A viewer watching Mcconaughey fall into a black hole would not see him "spread out across the surface" - it would appear that he decelerates asymptotically, and would appear to freeze as he reached the event horizon.

[@paharipant2]

This is a great video. It explains something weird comprehensively. Mind bending stuff.

[@henrysiegelson8342]

When I was in medical school, my neuroscience professor suggested that our brain works like a hologram. Billions of circuits creating billions squared of electromagnetic fields. Thus, we could imagine a pink elephant rotating above our hands. Our thoughts would create that image in 3D and we could "see" it with our minds. There used to be a Museum of Holography in NYC in the 70's. Where have all the holograms gone?

[@LaughingMan44]

I thought that 'deleted' information is just rendered into random code 'noise'. Information is just 1s and 0s, your file is a specific sequence of 1s and 0s, when you 'delete a file' that part of the hard-drive is just over-written with new information. That's surely how even seemingly deleted files can be found again so long as that part of the hard-drive the information was one hasn't been over-written. This is why one would scramble all the information on a hard-drive so those deleted files can't be found again. Correct me if I'm wrong.

[@JohnnyAmerique]

You are correct in that it is *practically* possible to make computer data unrecoverable, but it is not possible to delete the physical information from the universe. The "deleted" information is overwritten, but it is not physically destroyed - merely scrambled well beyond what any current or even imagined technology could reconstitute. Similarly, even if the physical drive is utterly destroyed with respect to functionality, the matter of which it is comprised isn't destroyed, it merely changes form.

[@isnerdy]

No appreciable amount of heat is generated by deleting a file. The primary source of heat in a computer is power being dissipated by processors. It's a factor of voltage, capacitive load, and switching frequency. The switching frequency is determined by the clock speed, and what you're actually doing with the computer. Disk access is one of the slowest things a computer can do, and will cause the processor to sit idle more, running cooler. The most power-hungry thing you can do to a processor is to loop a bunch of load word instructions for data that's in the cache. It'll never touch the hard drive, or even RAM - it'll just keep computing memory addresses and loading data from the cache into registers. Even within a drive, overwriting data is not a significant source of heat. In a hard drive, it's done by manipulating microscopic magnetic fields - the primary source of heat is actually the motor that spins the platters, which remains at a constant speed while the drive is on. Any heat generated from a write operation in a hard drive is more likely from the motor that controls the position of the read-write heads, not from the process of magnetizing and demagnetizing sub-sector areas. In a solid state drive, changing data is accomplished by changing the voltage of the inputs to microscopic logic gates. Changing a 1 to a 0 simply involves satisfying the logic condition (typically NAND, sometimes NOR) of the gate that will set it to False. Also not an appreciable source of heat. SSDs tend to run around room temperature. Power supplies can be a significant source of heat, but have no direct interaction with data. As others have mentioned, when you delete a file on your computer, the computer doesn't actually touch any of the data contained within the file. There's a database, called the directory, that has a listing of every file and folder on your computer - the names, sizes, creation and modification dates, as well as the position on the drive. When you delete a file, its listing is removed from the directory, and the computer can no longer find it. The computer then thinks that the space the file occupied is free, and it will overwrite it with another file at some point in time. Before that happens, it's possible to "undelete" a file by scanning the free space on the drive for data. But once the file has been overwritten, that portion of the storage is set to 1s and 0s of sufficient magnitude (whether that be magnetic fields, or voltage) as to make what was previously there unreadable. In a computer, the act of changing information is necessarily destructive, but that destruction doesn't happen when you delete a file. It happens at some unpredictable time in the future.

[@KornyOzzy]

I don't see the castle... I love your channel! Great content.

[@arturaskarbocius6091]

Holographic principle works with Fourier series as transverse waves strings and on water surface, every wave represents some matter gases have very low frequency, liquids middle and solids have geometrical structure and very high frequency, and eather is media Fourier superposition principle gives interaction between strings and brains as lens where by emerging of consciousness allows to understand surrounding world.

[@Ryanrichey13]

3:05 It's not a castle, it is 2 knights on either side of a horse jumping or flying squirrel or something

[@2104ster1]

when you delete your document, it doesn't convert into heat. the computer just "opens up" the space on your hard drive. that's why it's possible to retrieve it even after it was deleted. however if you then fill your hard drive with something else, it will overlap the existing information and create new information out of the old.

[@2104ster1]

also some theories suggest that the "inside" of a black hole has four dimensions. that's why Mathew seems to just stop.. as you say, he doesn't stop, he just appears to stop, but in fact he might be traveling through four dimensional space where "stopping" doesn't make sense, since he then exists in all of spacetime. - which of course is not possible for us to understand.

[@NachiFREE]

Love your videos! Inspiring and thought provoking, and dare I say life changing. Great work.

[@felizitasable]

I seriously love your videos

[@fodicky4]

You really explain information well...

[@bradywb98]

Maybe I'm missing something but near the beginning you use Hawking Radiation to explain how the matter/energy in a black hole is eventually destroyed. But it's not, it's just dissipated via the radiation. Of course entropy is at play at that radiated energy is at a lower "useability" state than it was before it became a part of the black hole (or even than when it was a part of the black hole) but it's still present in the universe. How is the Information Paradox a paradox when it's just explaining how entropy works? Like, of course the amount of valid information and usable energy in the universe decreases over time, that's just the way entropy works. Information is just diffused and decomposed into the Universe. This really reminds me of the "Five Ages of the Universe" which basically describes the life of the Universe until it's eventual heat death by grouping it into five different stages. The final Age is the "Dark Age" which takes place after the last black holes completely evaporate and the Universe is very low energy, consisting only of electrons and positrons that will eventually all annihilate each other and leave a matterless, energy only universe.

[@YisYtruth]

I have no idea what any of this means, but it sounds amazing.

[@ThatsWhatSheSaid-420]

I am having trouble understanding. Can somebody please provide captions in Stupid?

[@Frank7489]

My computer is hot but i didn't delete anything. Plz help.

[@Synodalian]

Information is stored as electrical bits on computer. Info gets deleted. Electrical bits on computer therefore get switched off. Therefore, the "switching off" creates heat. The information gets turned into heat. The end.

[@LeahLaushway]

That'sWhatSheSaid The principles of Physics describes how an object can be in two different states (or more, theoretically) at once. It's possible that what we perceive in our daily existence within this universe can similarly be viewed as being in a completely different state than how we'd describe it.

[@lunjemersic]

[@widdomonki238]

'you may remember these from gradeschool'. He's so young ;) damn things never did work for me.

[@NopeRyan]

Love this video. Found it very compelling and only slightly mind-bendy. One thing that really caught my eye was the desktop wallpaper you used, where can I find it?

[@josejerez4954]

So what you are saying is that a hard drive storage capacity is equal to its space? So why does memory get smaller every year? It may sound like a dumb question but definitely interested in the answer. If you give me answer like we get more efficient at putting information in to smaller spaces, then doesnt that contradict the first notion?

[@miahky]

You may be going in the wrong direction: instead of outside in, what if it is more inside out? More correctly, what if information contained in the circumference is reflecting the disorder between the so-called inner and outer?

[@Jugivadi]

I'd like to thank you for causing my head to explode. It was fun.

[@TheJaredtheJaredlong]

I don't believe you that that's a castle. And I don't mean that in the "hur dur I only see colored dots" sense, but the, when done properly, the image that pops out looks nothing like a castle. There's definitely a brick pattern, but if it's a wall then it's horribly destroyed. The guy on the left looks like a knight in armor, and it looks like there might be another one on the right side, but he's even less clear. I'm just really confused on what the big gash in the middle is suppose to be. Do you have a link to what the encoded imagine is?

[@numberpi5473]

+TheJaredtheJaredlong My god. It just looks like you're making a bunch of shit up. YES YES I know the effect is real. I say this because I have NO IDEA how to look at these pictures correctly.

[@TheJaredtheJaredlong]

Yashum Pi I'll try to explain the method the way I was taught. Hold up your pointer finger, vertically in front of your face, about 6 inches (20cm) away. Look at your finger so that it's "in focus", meaning you can see your own finger in as much detail as possible. Now - keeping your finger in place, bring the wall behind your finger into focus. When you've done this successfully, the details of the wall will become clear, and your finger will become fuzzy; most importantly, it should look like you now have 2 blurry fingers. The, "turn your 1 clear finger into 2 blurry fingers", is what you have to do with your eyes to see these pictures.

[@numberpi5473]

TheJaredtheJaredlong This sounds very easy to do (much more than the method taught to me before). I'll try it soon and post the results :D

[@verdigo1]

+TheJaredtheJaredlong To me it looked like a knight on the left with his sword down, a knight on the right with his sword at the ready and... some priest guy with his arms up standing on his tip toes in the middle?

[@VigneshMukund]

+TheJaredtheJaredlong The big gash in the middle looks like some sort of banner or a dementor.

[@videotrash]

Hi, great video! Though I'm not sure about some particular things: Why would a person - exactly while crossing the horizon - be incinerated an spread across its 2D surface? I thought this was more of a metaphor, than an actual physical occurence. That is, that the reason for why the informational content of the volume inside a black hole could be described simply by looking at the event horizon is actually that oscillations are being produced by the stuff that traverses its boundry, not because of the stuff being really physically disintegrated and smeared across it. As far as I know an outside observer would never see how the person falling into the hole crosses the horizon at all, but could only behold an ever slowing asymptotic process of approaching it, while the image would gradually redshift and fade away. Though I vaguely remember that there's a sixty symbols video out there, that possibly contradicts this idea. (Also: I thought that the holographic principle depended on string-theory being correct?) Anyways, I think the basic concept itself is truly fascinating and you brought that across really well.

[@headacherack]

I have always felt like we are living in a dream we can touch. In lucid dreaming they say you will have six-seven fingers...but we have five fingers in this dream.
