Is the Universe a Hologram?

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:

That's some vsauce quality stuff right there.

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.

Holy crap, didn't realize you did this video. The Good Stuff did one on the same topic in which we interviewed Leonard Susskind and we titled it the SAME THING!

[Explorium]

This was extremely fascinating. (The "Alright, alright, alright part killed me). Very well made video. Love your channel!

And remember! Reality is an illusion, universe is a hologram! Buy gold, bye!~Bill Cipher

2:55 How much drugs should I take to see a castle?

[MarshmallowMadnesss]

So I other words, our whole universe could theoretically be resting on the event horizon of a black hole in a larger universe?

Loving it man, truly enjoying your work!

[AmbroseReed]

I love mind-bending stuff like this. Interstellar was one of the best theater experiences I've ever had.

Awesome video!! (The stereogram in 3:00 is not a castle. It is a ghost in the middle with 2 knites in either side)

[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!

[Wiizl]

There is no castle in the stereogram. There are two knights and some kind of ghost in the middle

[KeshArt]

Thank you for the AMAZING content you provide.you sir...are awesome

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

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?_*

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.

I'm so happy to see a new video from you in my feed!

[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.

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!
