Hacking Reality [Official Film]

[Music] let us talk about infinity imagine opening your eyes and finding yourself surrounded by water and you cannot remember ever not being in that water the first question you might ask is how did I get here you've always been there what do you mean always when did I enter the pool you never entered the pool you have always been in the pool okay but where was i before I was in the pool that's the first question there is no before in which you were not in the pool you have always been in the pool okay but always like how long like a billion years no a billion years began a billion years ago huh okay okay okay but I must have been born at some point what was before me okay so like what's our communication disconnect here there is no before you you have always existed in the pool always forever infinitely yesh always [Music] okay so the point that I'm trying to make is that there are some concepts that we humans just cannot wrap our heads around and one of them is the idea of something having always existed and having no beginning we just can't really grasp that concept it just doesn't compute like if I told you this road literally goes on forever you'd be like I don't get it I cannot grasp infinity are we there yet nope let me close never get in there driving forever here's another one try and imagine nothing it's kind of impossible at first you might envision nothing as darkness but darkness is something it's darkness so then you might say is nothing just empty space well empty space is something it's empty space but here's something interesting about nothingness well we can't really grasp the concept of nothingness we can describe it with mathematics roll film please okay don't get it this won't be complicated and I'll do it real quick can I get some background music so there's this thing called set theory an in set theory everything inside a set is what exists and if nothing exists in the set then it is called an empty set and that is basically a mathematical representation of nothingness or simply the number zero it kind of represents nothing I mean the symbol zero is itself a thing but it can also represent a lack of things so you can see how we can describe nothingness with math even though we can't imagine it same with infinity we can't grasp it but we can represent it mathematically and use it to solve equations so at least mathematically infinity totally exists so why am I telling you all this because another one of the concepts that we have a lot of trouble grasping even though mathematically it is not only describable but actually well understood is dimensions higher than the third dimension so you see the square it has an x-axis and a y-axis when it has high added to it it becomes a three-dimensional cube it basically grows as Z access okay that makes sense a cube is a 3d version of a square but here's some weirdness my friends listen carefully and just like just like flow with me you can grow another access to a 3d cue and get a four dimensional cube just just like flow with me flow with now we can only proceed with our eyes and brains three dimensions like this Q so we can't really grasp this idea of a fourth dimension it's like hum what the hell four dimensions which is what you're thinking now but while we can't really see or perceive a fourth dimensional version of this cube we can at least describe it mathematically so just like this is a 2d representation of a 3d cube here's a two dimensional representation of a 4d cube there's also a 5d cube a 6d cubed a 100 d cube and so on and not just Q's all shapes have higher dimensional counterparts theoretically there are endless dimensions and while we can't see any of them we can describe them using mathematics [Music] yeah every time I update this operating system anyway now about all these dimensions existing just take my word for it you do not need to come to terms with the existence of these dimensions in order to appreciate the bonkers weirdness of what I'm about to tell you about the eighth dimension so in this movie I want to tell you about a particular geometric shape actually it's not so much a shape it's really more structure an eighth dimensional lattice known simply and mysteriously as e8 now that I got my 8d glasses on I'm gonna watch me some 8d TV for some reason this 8 dimensional thing known as eh appears to encode all of the particles and forces of our three-dimensional reality so let's talk about what a 8 actually is and what it is is actually pretty simple for reals imagine circles all of them the same size we draw them on a piece of paper stacked in the densest possible way that one can stack circles of the same size this happens to be called hexagonal packing by the way now let's put a little point in the center of every one of these circles and now let's get rid of the circles and leave only their center points so now we have something called a point space this point space is one that represents the densest packing of two-dimensional circles of the same size right now let's talk about the densest packing of three-d circles or spheres again all of them of the exact same size PS we're totally pretending that these oranges are perfect spheres of the exact same size so the densest packing of three-d spheres is actually pretty intuitive to us it's how we pack oranges in the supermarket by the way this is kind of weird but it was only in 2014 that someone was finally able to prove mathematically that this packing of three-d spheres is actually the densest weird right it was like this big mysterious problem for years in mathematics that nobody was able to prove [Music] now let's add points in the Centers of all of our spheres while they're in this dense arrangement and again let's get rid of all of the spheres and keep only the points that represent their centers okay so now we're left with the point space representing the densest packing of 3-dimensional spheres so far so good right y'all with me okay so II eight is the point space representing the densest packing of eight D spheres strings please now many of you have heard of Albert Einstein's theory of relativity it's a theory that describes among other things how gravity works and how it affects massive bodies like planets and many of you have also heard of quantum mechanics it's a theory that describes very small things like electrons no one has ever been able to unify these two theories into what we colloquially call a theory of everything or more technically quantum gravity theory but for years now there has been a theory that is claimed to be a serious contender in unifying these theories and you've probably heard of it it's called string theory problem is string theory has kind of failed for years it has been getting tons of funding and grants in academia but it has never produced any successful predictions there are many physicists out there who think that the time of string theory is over and that eh may play a more serious role in an eventual theory of everything [Music] so string theory definitely applies to paragliding not sure much else if you got again string theory what don't I have again straight [Music] my name is Garrett Lisi and I live in Maui because why would I live anywhere else I was the person who first discovered by a match between particle physics and dat and when I first discovered it was so incredibly exciting I knew as me working on this probably the rest of my life I came to Maui because I got my PhD in theoretical physics and I thought about going off to do a postdoc somewhere but pretty much everywhere I looked wouldn't allow me to research what I wanted so I decided to split off to Maui and be a surf bum and work on what I wanted here in the 90s string theory was the hot research topic that everybody was going for and I looked at string theory and I just thought it was kind of far-fetched I thought they were making a lot of unjustified assumptions about the way the universe works wasn't a bad idea when it started they just over-promised and under-delivered what did they promise theorists promise to figure out a simple elegant description of fundamental physics using a few simple principles and it out early elderly failed to do that they kept piling on more and more complications until the theory just got ridiculous what was string theory people say about what you just said if they're honest it agrees but you know people get very attached to the ideas they're working on and after a long enough time becomes hard to let them go and move on to other things string theory has a lot of inertia because you have grants in place that support the projects that are being researched and you have students working on string theory problems they've started their dissertations which in the last many years that's one good thing about working on your own if you just decide the approach you're taking is not gonna produce results like you thought it was you can just wipe the slate clean work on something else as a graduate student I really fell in love with Einstein's theory of relativity his description of gravity is curving space-time okay so super nutshell explanation of how gravity works according to Einstein's theory of relativity now this is a big oversimplification so science nerds do not hate on me basically the idea is that space is a kind of fabric and objects such as planets sit on this fabric and make it sort of bend or curve so that other objects like other planets will fall toward it heavier objects cause a heavier curving of space or a stronger gravitational pull meaning objects fall towards them faster so this is a very geometric description of gravity when I studied particle physics it's just it wasn't a geometric theory in the same way that gravity is described as curving space-time so I wanted to understand a description of elementary particles that matched up with Einstein's theory of gravity because the universe is just one thing right so there has to be a unified description of this place where we are living when you do fundamental mathematics you invariably see these very elaborate complicated beautiful mathematical structures that come out and it just so happens that some of these beautiful mathematical structures describe our physical universe we know of these forces that exist in the universe all right in gravity electromagnetism weak force the strong force and we have this whole spectrum of elementary particles and properties so this is an idea that's been around for a long time and I'm gonna describe it using a hypothetical scenario imagine if we lived in a two dimensional universe a totally flat universe all particles atoms people buildings all are totally flat like a cartoon okay so in this 2d universe all particles such as electrons quarks photons would all be two-dimensional so let's take one of these hypothetical two-dimensional photons for example the idea is that there is a circle attached to it in the third dimension sort of above this 2d universe in such a way that the photon is actually just a point on that circle and that point appears in our 2d universe as a photon we cannot see the entire circle popping out of 2d just the point of the circle that touches our universe this circle is called a fiber the fiber represents how the photon moves through space and time so a photon is represented by just this one circle and other particles and forces are represented by different combinations of circles the fundamental force known as the weak force for example has three circles that twist around each other in certain ways these groups of circles form what are called Li groups okay so that explanation assumed a hypothetical two-dimensional universe but in our actual universe which is in 3d the fibers attached to our 3d space are in even higher dimensions so physically we live in three-dimensional space and there are these other higher dimensional fibers attached to every point of our space and as these fibers twist over our space and time that appears in our space as particles propagating from one point to another this is what all matter all forces this is what everything is this description of particles is entirely geometric all the forces we know of they're coming about from the curvature of these fibers the same way gravity as the curvature of space-time and this is this has actually been known and standard in physics for for you know over seventy years now so this idea was exciting for a few decades but then people sort of forgot about it and started working on string theory but string theory is you guys know didn't pan out so well so Garrett took a big step backwards and tried to combine the theory of these circles with gravity and some interesting things happened so just like numbers you can add the groups like you can literally add groups of circles into larger groups so when Garrett added together the Li groups representing each and every force and particle in nature that we know of along with the Li groups representing some theorize but not yet seen particles such as the graviton which is a theorized gravity particle they all formed this one big Li group and I mean a really big regroup one that has been known about in mathematics for years and you guys already know what it's called it's called eh ei tis considered by many mathematicians to be the most beautiful structure in mathematics it just so happens that there's there's this correspondence between the particles we see in nature and this most beautiful mathematical structure ever discovered and there are some discrepancies we're not sure exactly how it will work or whether it will work at all but there's enough of a matching between the known properties of on which particles and and the structure of this geometric mathematical object it's very promising very encouraging for describing physics so to really simplify this and again science nerds don't hate on me I'm just trying to give you a simple visual imagine if behind every particle we see in our 3d world there is this eighth dimension sort of EA machine behind the scenes that turns and rotates and when we view a particle in our world we see it as an electron or quark or photon or any other thing according to what this EA machine is doing over there in the 8th dimension and according to its orientation relative to our world so all particles and forces and space-time itself can geometrically transform into one another according to the geometry of EH so are all particles the same somehow yes they're all they're all different fibers of this EA tlie group well that's just weird and that great so it's weird and mysterious that a point spaced in eight dimensions is so somehow fundamentally related to our three-dimensional reality isn't it yeah that's weird I mean it's wonderful and mysterious why mathematics worked so well to describe our universe at all our physical law is the fact that they're accessible to us and that some fundamental bits of mathematics actually describe our physical world that's really remarkable like we're living in a bit of mathematics that's come to life then you go one step larger in the size of your tetrahedron and then ten steps larger than a million steps larger all of the breakthroughs in physics have come from people willing to step outside the box and do something creative and radical hi my name is Clare Irwin I am the director of quantum gravity research working on a theory of everything called emergence theory I've given up every other focus in my life I quit my job as an executive years ago to focus on this everyday with a team of physicists and mathematicians who work with me what is reality is reality made of energy and if so what is energy is reality made of information and if so what kind of information is it is it binary made of zeros and ones is the universe a a binary computer okay so in cleese theory reality is at its most fundamental level a code or a language and this code relates deeply to e8 Klee envisions a substructure of space and time at the tiniest possible scale you know how your TV screen is broken down into fundamental units called pixels well immersions theory suggests a three-dimensional pixel of reality a fundamental building block that everything is built from the tetrahedron which is a three-dimensional equilateral triangle these tetrahedra combine with one another through various mathematical rules throughout all of space into a massive structure Klee calls the quasi crystalline spin Network and this network isn't some random arbitrary idea it comes directly from e8 so now you have a conundrum because you have this mathematical idea that reality relates to higher dimensions and yet you're measuring or observing 3d so the only solution that we can think of is quasi crystals quasi crystals that's a mouthful some people call them quasi crystals okay so let's talk about what a crystal is first a crystal refers to a type of pattern a periodic pattern a checkerboard is an example of a two-dimensional periodic pattern where if you extend it infinitely it'll just be the same pattern forever you can also have three-dimensional structures like this cubic lattice now imagine projecting a three-dimensional cubic lattice to a two-dimensional surface you create a shadow this shadow also has a pattern but it isn't periodic it also isn't random it's a periodic a quasi crystal a quasi crystal in a certain dimension is a projection of a crystal in a higher dimension remember those points representing the densest packing of circles and spheres actually those points are arranged in a crystalline order now the e8 lattice is actually an eighth dimensional crystal and cleese group projects this ei crystal from 8 D to 4d to 3 D at a specific irrational angle to form their theorized fundamental substructure of space-time when I make an irrational projection of EI down to a lower dimensional shadow of e8 something remarkable happens the object becomes a language that is it becomes a finite set of geometric letters rules on how you can arrange those letters and freedom within those rules which allows you to express or encode information so this three dimensional quasicrystal so this three dimensional quasicrystal is essentially a geometric code a code composed of symbols which Express meaning and this meaning is reality itself string theory speculates on a number of hidden dimensions and when we asked well why can't we measure these dimensions and observe them then the answer is well because they're too small to see in our approach we never have to introduce the higher dimensions because we get the same information of the higher dimensional math encoded in the three dimensional dynamic quasi crystal language mathematically one can recover the information of the e8 lattice that encodes unification physics from the lower dimensional quasicrystal to me to be able to even have a one-in-a-million shot at discovering the very keys to the fabric of reality is just fun like what what better treasure hunt could one have I think that the world is getting crowded and there's a lot of people not having fun because they're focused on getting enough water that's clean or food and perhaps understanding the deepest secrets of nature at the smallest scales will be like having the keys to the kingdom so imagine if we discovered the very fabric of reality in explicit detail the very workings at the pixilated scale of reality that should open up a treasure trove of new technologies and perhaps even new philosophies relating to the strangeness of quantum mechanics that allow things that we couldn't imagine the road to knowledge is a long and winding one filled with moments of glorious scientific discovery but also ones of bitter disappointment whether or not Klee and Garrett's theories become accepted as mainstream quantum gravity theories many physicists believe that reality is deeply related to higher dimensional objects he ate perhaps as real as it is mysterious appears to be a real contender on the road to discovery theory of everything [Music] hey can you reward them for sitting through that whole explanation with like some 80s rock and roll [Applause] [Music] do you member last year when I did this science documentary though what is reality I think I think I sent that to you I can't really remember but anyway um my most favorite part about that was um this part about matrices and there was this word in it but I wasn't quite sure on how to pronounce it looked to me like vegan value so right I mean I think that's what you would think you can value so I asked is this how you pronounce it and David the director said yes that is how you pronounce it so I went out there and said that's right egon value and then apparently the internet went nuts when it came out because apparently it's pronounced eigenvalue that's how you're supposed to say I'm the director don't bleep me the fing director told me to say egon value and it's eigenvalue and the whole internet just like caved in on my skull and it's just kind of been awful but like I get it and I just feel like you know I want to understand these kind of things it's just nice to get it off my chest but it's just like man I can value eigen value eigen value [Music] you [Music]

HACK THE PLANET!

[u/davidjaku]

Is there an 8-dimensional "engine" behind our universe? Join Marion Kerr on a fun, visually exciting journey as she explores a mysterious, highly complex structure known simply as 'E8'--a weird, 8-dimensional mathematical object that for some, strange reason, appears to encode all of the particles and forces of our 3-dimensional universe.

Meet surfer and renowned theoretical physicist Garrett Lisi as he rides the waves and paraglides over the beautiful Hawaiian island of Maui and talks about his groundbreaking discovery about E8 relates deeply to our reality; and learn why Los Angeles based Klee Irwin and his group of research scientists believe that the universe is essentially a 3-dimensional "shadow" of this enigmatic... thing... that may exist behind the curtain of our reality.

Thanks

[u/BerrettLee]

thanks for your sharing! I was needing that, day by day life was making me forgot concepts attached to my perception like the infinite one, i feel less anxious now

[u/spacesoulboi]

This Beyond the next level

[u/live52]

It should be said that the runtime of this documentary is less than thirty minutes—a small investment to have your mind thoroughly, and entertainingly boggled. The concept reminds me of Plato's allegory of the cave. Notice that OP is also the writer, director and editor of the film. Thanks Mr. Jakubovic.
