Isaac, I had a teacher like you in high school. After a semester of his lectures (and I've been watching your channel for years), I don't even notice it anymore. Keep doing what you're doing, Ad Astra!
Notice what? His speech impediment? If you're trying to compliment him by telling him you don't notice his speech inefficiencies that's a ridiculous compliment. I actually enjoy the speech impediment, like the way his says "paper" very unique voice to carry very unique information, and there is no ignoring it. That would be like trying to ignore a strong French accent and saying " I don't even notice anymore."
Arthur video is amazing. Please never change your format to conform to the algorithm. It’s the perfect blend of science and science fiction. The videos are just long enough to explore a concept with adequate details or possibilities too make me think. I’m also a huge fan of your longer videos.
I appreciate your respect for axioms even when you don't hold them yourself, and considering them in earnest. You explain what physics and faith actually are quite successfully while taking into consideration they deal with different things. Thanks for your work
As an old science , civil engineering retiree I put natural science and theoligical to scientific and etomoligy translations. Thence applying physics of energy and mass to comparitives of theoligicals . Interestingly, quantum entanglements and natural classical sciences of knowns formed an interesting parrallell including all historics to plausable energy forms and especially when combined with matter forms within human detection to which jibed to more than swamp gas and auroras !
At least in the 3rd Dimension we can convey feelings like Love, Happiness, and Sadness on a physical level-- nothing is better than touch. As an infinite being, you can't touch anything because you are Absolute and are everything.
I enjoyed the Dark Forest strategies outlned in the Three Body Problem series. There used to be 10 dimensions, but every now and then some species somewhere would invoke a dimensional strike that entirely disabled an entire dimension, leaving us with the three we know of and reducing the speed of light to what it is now. A species would learn to adapt to life in lower dimensions and strike one off, knowing that other species couldn't survive the transition. Like the Singer targeting our solar system as ground zero for an ever-expanding reduction to two dimensional universe. The description of the transition as the borders of 2D space expanded to consume literally everything and map it all on a paper-like plane was fun to imagine
I was visualizing the opposite as I read. The whole 3D universe being shrunk to fit on an infinite plane. It would kill everything in the universe except what was already existing on the plane. Eerie
Well, we should have used the slow fog and figured out the black domain since it was spelt out for us in those tales but alas Ye Wenjie doomed us regardless with so many hunters lurking it was inevitable. But glad you had fun, this was only time I shudder at the thought of concentric circles 😂
I thought 1 and 2 d space were conceptual only as they cannot exist independently as nothing can have any substance without a third and fourth dimension , the fourth being time to enable actions .
I think you're leaving out a couple of things. Dimensional bombs would reduce the dimension of an area, and the effect would spread and could not be stopped. The universe as we see now is a result of that effect spreading so far and reducing the dimensions from 10 to 3, leaving some pockets of 4-D. But the effect doesn't stop there either. As time goes on, our 3 dimensional life will continue to reduce to 2, and we would die with that.
I love all the episodes on this channel, but I especially love the more occasional out there ones. I’d like to imagine the idea of two civilizations communicating in different dimensions by making sculptures of themselves in the other’s dimensions. To the higher one, the lower would look like a stick figure on paper, and to the lower it would be some semi- incomprehensible shape. Maybe not possible but it would be an interesting first contact!
Greg Egan's _Diaspora_ has the colonization of a higher dimensional universe as one of its plot points. It's amazing how singular he is in incorporating such far-out ideas into his fiction, I feel like so many of the concepts in further-afield episodes such as civilizations at the end of time or false vacuum decay have only been touched by his works. Wish there were more of him.
Fantastic book and possibly my most re read . Schilds ladder another blinder too . The book gives future exploration a whole new dimension lol . Yatima right to the end and back to the coal face ! wow.
@@MyKharli I'll be honest, I think it kinda falls apart at the ending, like Egan _really_ wanted the ending to be Yatima alone doing math but the plot forced Yatima & Paolo together. It (and _Schild's Ladder_ as well as his classic _Permutation City)_ still legitimately blew my mind when I read it, and I consider them peerless when it comes to concept novels. Special mention goes to the Wang's Carpets chapter, another vertigo-inducing what-if.
My favorite version of higher dimensional aliens is the Orz from Star Control 2, mostly because you never get a full, accurate translation matrix for their language and so their dialogue is full of "best fits".
The weirder thing is that BOTH higher and lower energy aliens were introduced in Star Control 2 (the Ariloulaleelay and Orz, respectively). The Orz are notable because they actually inject a conscientiousness into our universe, completely replacing the Androsynth in a form of Fermi Paradox. Because they are essentially Cthulhu, incredibly badass, and creepy. And when you visit the Ariloulaleelay in their own dimension, the X/Y coordinate system makes very little sense. That game is such a masterpiece.
For deeper discussion of the interaction of entities from different ontological planes I recommend the video “darkseid is not a god, he’s worse” From the imaginary axis
@@cosmictreason2242thank you so much, gunna check this out now! I have an idea for a sci-fi fantasy story regarding higher dimensional beings and the occult, so looking into everything I can find. Thanks again!
First time I’ve heard discussed something I’ve wondered about with regard to higher dimensions: whether there are more than just one dimension of time. I’ve always wondered whether multiple time dimensions (woven together in our normal experience of ‘time’) could resolve to unravel time-travel paradoxes and the speed-of-information limit. Thanks for broaching this topic, and please consider a deeper dive into theories of time for a future episode.
I alway thought that the random nature of quantum decay could reflect that the universe has another time dimension and that the decay might make sense seen from another time dimension.
You could have one time dimension that works normally being unable to move in any direction in it but forwards, and then another time dimension that you more typically experience and that can be travelled around in. So instead of the grandfather paradox you are constantly moving forwards in time dimension two, but in time dimension one you went back in time and killed your grandfather but you still exist.
@@atashgallagher5139that’s a cool idea. It makes sense too. It’s kinda the same as our big bang being part of a larger multiverse. In this senario Our time is just part of a much large(or infinite) multiverse of times.
There are a couple of 4D games under development. One called Miegakure: Hide and Reveal (a puzzle game), the other being 4D Miner (a 4D Minecraft clone with a demo available on Steam). Already available is 4D Toys, which is a sandbox of 4D objects with VR support if you can afford the hardware, and can be played with a keyboard and mouse if not.
There are several people I would love to meet that I watch on RUclips and you are one of them! Absolutely incredible content you are certainly one of the best

Been waiting for this episode Isaac!! Thank you, and hope you had a great weekend buddy, and the smoke from all of the fires up north here didn’t cause you and your family too much distress!! 🔥🇨🇦🔥🤦♂️🍻
@@spencervance8484 vandals set a bunch of fires in canada and the smoke has covered much of the northeast US. its pretty obvious that vandals set the fires - satellite imagery shows them all starting at essentially the same time.
I can understand why you would want to modify your speech, but I must confess I had no problem understanding you before. It was what made you an individual and very distinct. I grew up with a sister who had a speech impediment and maybe that is why it isn't an issue with me. Best wishes to you Mr. Arthur.
Perhaps the idea of a multiverse or quantum-universe where "everything that can happen does happen" is really just how we experience existing restricted within a single "slice" of a higher-dimensional reality. It might even explain quantum entanglement, since starting in a particular "slice" of something would necessarily make another particle correspond appropriately.
It would be difficult to discern the difference between alien entities that are interdimensional from entities that use other dimensions to travel and communicate. To us both would appear to be interdimensional.
Isaac, I've been following your videos for years, except the past year when so much was going on in my life that I had a hiatus. I'm happy to come back and see you are doing as well as ever, or better. You're work is incredibly inspiring to me, and for the looks of it, I'm not alone on this. Thanks. Wishing all the best for you and your family.
Hey Isaac, this video reminded me of what the caller in the 1997 Art Bell radiostation incident said. With him claiming that aliens have access to more dimensions than us. The idea of extra-dimentional aliens sounds bogus but it’s an interesting expansion on the whole concept. It would kind of explain the whole “aircraft moving in ways that defy our current understanding of physics” thing, with them also poking in and out of our reality at will XD It sounds like history channel levels of delusional but it’s growing on me
"Okay, um, um, okay What we're thinking of as, as aliens They're extradimensional beings That, an earlier precursor of the, um, space program they made contact with They are not what they claim to be Uh, they've infiltrated a, a lot of aspects of, of, of the military establishment Particularly the Area 51"
don't forget "A wrinkle in time" for Tesseract fame! That's how I first heard of it! also i am in awe of the guy that went through so much effort to make a suit out of the thumbnail art of your channel!!!
I think the most interesting take on higher dimension aliens is the Law of One series. I have for years studied fringe religions, and treat every single one as agnositically and respectfully as I can. I hope I dont mess it up to much or get too much wrong but as I remember Law of One is one where people believe that our souls grow and become greater, eventually moving up dimensions can inhabit higher dimensional bodies. I think at like 5th dimension they believe you shed needing to inhabit a body completely and exist as a light being that can interact with lower dimensions. This is where we get like gods, angels, demons, and stuff. Most notably they believe Ra (the very same Egyptian god) is one of these higher density light beings which has taken an interest (among other high dimensional beings) in seeing humans throgh to the 4th dimension. It's a really interesting read and tbh I honestly believe it's one of those religions that sounds super wild, but the message is super good and peaceful.
Hope you've recovered/are recovering well from surgery, the bit at the end does sound a wee bit clearer for me, since you asked. Thanks for making interesting videos :)
I loved science fiction comics as a kid, i remember well a story that scared me and fascinated me at the same time. It was about a odd family that drew too much attention to themselves and it was dimension hopping "aliens" my theory was they might have humans that lived under so different conditions that they didn't look human. That was my first thought about alternate dimensions. And what they might be like.
Favourite channel for gentle mind stretches at the end of a long day 😌😌 Don't buy into extra physical dimensions myself. Though I think different scales, in time and space, are super interesting.
(Rational animations) made a video called (that alien message) that tackles a lot of the topics near the end of this video about colonising higher dimensions.
This martial approach makes it very clear why intelligent beings are observing us and not trying to make contact. They must be concluding "another failed attempt here"...
Main line this right to my brain...makes my brain happy. Talking on reality vs trying to fit it thu the lens of some ego. Give me the real stuff everytime.
TY SFIA! I try to think of dimensions as degrees of freedom. x,y,z is three. t is 4. 5 and above are just more degrees of freedom (c, l, r, m, delta, gamma, theta, omega, etc.) We live in a universe that has as many dimensions as we have letters from 3 alphabets to describe and observe.
I can't help but wonder how well our stereoscopic vision could interpret a 4d object. I feel our brains could adapt to whatever they experience. But could we actually experience a 4d object with the senses we have?
that is a very interesting question, as even the fundamental lens focusing light onto the retina will drastically be affected by how the eye shape is translated into the higher dimensions. the ability to determine up/down left/right and depth may be drastically reduced or exaggerated, and the ability to determine a 4 dimension may end up mixed in as XYZ or replace one of them while XYZ gets flattened to XY, or some mix of time perception, or gifted with 4+ dimension sight, so many ways that can go. As far as mentally adapting, I do agree that it is possible as any computer can calculate more than 3 dimensions with some work (that has been done already for some things). oh, and then I have the thought, does light even propagate along the extra dimension, hmm (shrugs). maybe it's something like how the shadows (or whatever) cast in the 4th dimension are seen in the other 3.
It's a great question. I don't the answers obviously but my inution is that we'd briefly notice something odd then our brains correct it. Kind of how peripheral vision works.
@Zarcondeegrissom I could be wrong on this but as I understand it, light would not propagate through higher dimensions since our math for intensity (that's the Wattage per area) only make correct predictions when we assume light spreads out as a sphere. Not a circle, line, or hypersphere. Likewise there are some elements of higher level physics which work the other way: the only way to make an equation work is to assume dispersion across higher dimensions. I believe this is a (very broad) reason why M-theory requires 11 dimensions to work correctly Edit: literally just started watching and Isaac said like half of this lol. My b
I've wondered about this as well. I agree with what you say about our brains, but our eyes are physically 3D. So, I though about what a 2D creature might see in our world and I realized that his 2D eyes can only see 1D images. If he has at least two 1D eyes, his brain could form an idea what 2D looked like, but in a 3D world, he would still only ever be able to see a slice of 3D that was "in the plane of his 2D body" He would see whichever slice of objects he was pointing at. If he is rotating in 3D, then the things that he sees are shifting in strange ways as the plane of his perception swept around. I think that is what we would see in a 4th dimension - we could see shapes and surfaces, but they would all look like constantly shifting 3D objects to us. We might see a large globe with 5 smaller globes floating around it and not understand that this was a 4-dimensional "hand" and 5 "fingers" of a 4D being, because we are only seeing part of it.

I haven't watched you for a while but I did notice an improvement right at the beginning. I'm glad I watched to the end to find out it wasn't just me. Congratulations.
This 4th dimension is used well by Tad Williams in his Shadowmarch series, where a god discovers how to travel this hidden road. He was able to move along it unseen by the other gods, but the journey from his perspective felt almost eternal and impossibly far. Not only did he escape their notice, but he was able to bypass their fortifications. @11:30
After the introduction my first thought was "is this a reference to the three body problem"?? You know, - !!!SPOILER ALLERT!!! - dimensions-collapsing weapons and what not
You can embed flat 3D space on the surface of a 6-cube, with 64 flat cubic volumes with 192 vertices (singularities), although intrinsically it is a flat 3D torus looking like a 4x4x4 matrix of cubes where leaving one side re-enters the opposite sides.
Congratulations with the successful operation. I can clearly hear a completely new level of expression in your voice and to shine much brighter. You clearly have a new and wonderful Flair.❤
the problem with moving between dimensions would be critically dependent on subatomic particles. The quarks of our dimension evolved 3 different generations of particles with the same chirality, spin and charge. Only differing in their intensity. Doubtless a different dimension with an extra number of dimensions or different properties than ours would have quarks that have more generations, or force carriers which don't exist in our universe. This would change how atomic mechanics work, and affect how chemistry works. Maybe they have something better than oxygen and carbon for life to construct molecules with. BTW Tesseracts probably entered public consciousness with Madeline L'Engle's Wrinkle in Time series. Popular YA sci fi books.
I definitely hear a difference. You are so much clearer with what sounds like less effort. Congrats on the surgery, I hope you like how your throat/tongue feel now.
4+1 spatial dimensions. The 4th explains the experience of weight as you use more energy to increase velocity in the extra dimension. The 5th limited spatial dimension is causality. Time is a human construct.
With the ufo disclosures coming out lately, and some of the craft described. If true, would maybe mean we have evidence of type 1, type 2, or even type 3 civilizations. 1 of the vehicles was described as being much bigger on the inside. Able to rearrange space/time. Exciting times ahead if true, lets hope everything is disclosed and released along w/ all recovered technology. Could be pretty epic to leap-frog our civilization by 500 years or more.
@12:58 not necessarily, we don't know this for sure as we don't have any way of testing this. In regard to the perturbations, there's no reason to think that if gravity scaled with dimensions, the other forces acting on orbits (such as the speedup) wouldn't increase as well, balancing everything out.
All the people here whining about issac arthurs voice should shut up and be more respectful he has a lisp and cant help it at least he takes the time ro amke quality videos for us to all watch instead of complaing or making fun of his lisp dont watch his videos than if you think you can do better than him by all means show us ...and also some ppl mentioned to use AI voice overs well those suck
Several years ago I left my body and saw a linear drawing before me. I'd never seen anything like it before. I hurriedly returned to my body and sat at my desk in an attempt to replicate what I had seen on paper. I couldn't do it. There simply wasn't enough room. i.e., enough "space" to do so. I needed another dimension. Will never forget it.
"“…every figure of space is but the result of the intersection by a plane of some corresponding figure of one more dimension - as a square is cut from a cube or a circle from a sphere. The cube and sphere, of three dimensions, are thus cut from corresponding forms of four dimensions that men know only through guesses and dreams; and these in turn are cut from forms of five dimensions, and so on up to the dizzy and reachless heights of archetypal infinity.” Through the Gates of the Silver Key
Regarding the 2D life, if someone has any issues understanding the concept, I highly recommend Tibees' short videos where she discusses stealing from 2D beings, very visual and intuitive explanation of how dimensions interact.
honestly that is the biggest end all to high dimensional entitys. HOW TO GET THERE and vice versa as you said and its likely never gonna be a actual "gateway" or any physical doorway more like a IRL exploit where you do a specific combination at certain times and "leave the map"
That's utterly retarded. Reaching a four or five-dimensional plane is not like doing a ritual and going to some magical world, no, it's just a higher physical plane where native 4D beings reside
That’s why you don’t get to heaven hell through a portal, unlike as seen in doom or 40k, you get there by dying, which is when your immaterial component disassociates from your material component and is able to go to immaterial-only realms
@@cosmictreason2242 yep its ironic in a way that science actually gives more clear methods to describe abstract concepts like afterlife realms. even if science at its nature is outright opposed to the supernatural at certain levels of understanding the diffrence becomes null and void. clarkism or clarketech is how i think thats often refered too.
Surprised you didn't touch on dark matter in this episode. It seems like it could fit there given the interaction seems to be limited to gravity. Also black holes could have some aspect of an extra dimension since normal physics break down within them.
I have a question, how does the 3d world look from the higher dimension spitial dimensions? Do 4D aliens also go blind if they stare at the sun for too long? Does the sun have a 4d component(i dont mean time when i say 4d but rather extra spatial components)
I also want too say, I feel dreams are extra dimensional. I don't know howmany times I have been dreaming and as I'm waking up my understanding of what it was about fades away. It's the weirdest feeling.
@Bleys1973 I totally feel this too! Like right after waking up, I’m thinking in detail about the dream, then 30-60 minutes later, I’ve totally forgotten the details. The fact that I even thought about it or dreamt it in the first place so recently feels rather foreign and out-there. It’s very odd.
As far as I'm concerned, dreams are just running DEFRAG on your hard drive and getting a glimpse of the data as it's being moved. If you had something like Johnny Mnemonic's brain-drive, then you could probably see the data you were carrying when dreaming, even if it didn't show up when awake.
i believe extra dimensions are much larger, not smaller. in some cases we r like a plank length to other dimension realities. this takes multiverses to the level of superverses...we r within superverses and not adjacent to multiverses.
I'd like to recommend the book, Death's End by Cixin Liu (sequel to The Three Body Problem and The Dark Forest). No spoilers, but it's incredibly topical.
Ah, a subject that is dear to my heart! (My avatar is a 6D Hypercube) 😁 Anyway, may I also recommend the book "The Planiverse" by A.K.Dewdney - a very enjoyable book that talks about 2-dimensional life and goes into a lot of detail about how it might work. 😄
@@stormstaunch6692 It is a still from an animation I did called "Tour 6D" where I start from a single point, transition to a line, then a square, cube, tesseract, 5D hypercube, and then 6D hypercube - and then back down to a point.
@@stormstaunch6692 They are all higher-dimension geometric objects. They share a similarity in that each one of them can be 'stacked' or 'tiled' to fill all of space - depending on the dimension. So, start with a single point or vertex. It has no dimensions, so it is considered a 0-dimensional object. To make it into a 1D object, a line, you must make a copy of the point some distance away (1 unit for simplicity), and then fill in the area between. A line is the only kind of 1D object you can make. It has two vertices and of course the line itself. You can stack lines next to each other to fill all of 1D space. There is no need for this in 0 dimensions, because all you can fit in there is that single point. Next, 2D. If you make a copy of that line at a right angle to the single dimension that is there already - let's call that length, so we are adding width - then connect those two objects together, we get a square. 4 points, 4 lines, and 1 square. You can make a grid to fill all of 2D space, each square acting like a pixel on a computer screen or a box on grid paper. Next, make a copy of that square and move it 1 unit distance away from the original at right angles to both the width and length dimensions - height - fill in the space between and we have a familiar cube. 8 points, 12 edges, 6 square faces, and 1 cube. Again, all of 3D space can be filled with a grid of cubes - voxels are the 3D equivalent of pixels. We can also start to see some patterns that help figure out what might come next in this progression. Every next higher dimensional square/cubic object is formed from 2 X the current dimension 'faces' of the next lower dimension. A 3D cube has six square faces. a 2D square has 4 line 'faces'. A 1D line has 2 point 'faces'. So, a 4D cube should have eight cubic 'faces' and that is correct. There is a simple formula to figure out all of this stuff, since we are making a copy of an object, projecting at right angles to all the dimensions that contain it, and then filling in the gaps. If m is the number of faces, edges, or whatever in an object and n is the number of the next lower dimensional parts then to find the next higher dimensional equivalent it is new m = 2 X m + n. I know that's a bit confusing, so an example: to mathematically figure out what a cube would be from a square, start with the points of a square. m = 4, since there are 4 points and n = 0, since there is nothing below a point in dimensions. So, 2 X 4 + 0 = 8 points in a cube. Next the lines: m = 4 (lines in a square) and n = 4 (points in a square), so a cube has 2 X 4 + 4 = 12 lines (edges). For squares (faces), m = 1 from the square, and n = 4 lines (edges), so a cube has 6 faces = 2 X 1 + 4. The cube contains one cube, obviously, but this also works mathematically: m = 0 cubes in a square and n = 1 square in a square; 2 X 0 + 1 = 1 cube in a cube. This pattern continues as high as you would like to go. Also consider that it is valid to call a square a 2D cube, or to call a line a 1D cube, a point a 0D cube, or you could even call a cube a 3D square, etc. The next step is pretty easy mathematically, but the problem is I cannot show you what a 4D cube (also called a hypercube, or a 4D hypercube, or a tesseract, as well as a few other names) looks like because we are all hopelessly mired in 3D space (not counting the temporal dimension of time). We can describe a tesseract, project what it's shadow would look like in 3D space (like what a cube's shadow would look like on a flat projector screen) but we can't *see* a tesseract in the same way we can 3D and lower dimensional objects. All that being said, running the same formula again, a tesseract has 2 X 8 + 0 = 16 points, 2 X 12 + 8 = 32 edges (lines), 2 X 6 + 12 = 24 square faces, 2 X 1 + 6 = 8 cubic 'faces' (also called cells), and 2 X 0 + 1 = 1 tesseract. The pattern continues in five dimensions. This object is called a 5-cube, 5D hypercube, pentaract, and other names. It consists of 32 vertices, 80 edges, 80 square faces, 40 cubic cells, 10 tesseract 4-faces, and itself - the 1 pentaract. A six-dimension hypercube, 6-cube, or hexaract would have 64 vertices, 192 edges, 240 square faces, 160 cubic cells, 60 tesseract 4-faces, and 12 5-cube 5-faces, and the hexaract itself, of course. Whew! All of that with a little bit of math and a lot of intuition, analogy (from lower dimensional analogs), and the genius of the mathematicians who first conceived of these objects, like Ludwig Schläfli, Harold Coxeter, Eugene Dynkin, Jonathan Bowers, and George Olshevsky. Fascinating stuff!
i read some speculation that adding another spatial dimension would likey add another electron shell to atoms which would totally rewrite the periodic table.
_The Planiverse_ by Dewdney is an expansion of the ideas from _Flatland_ to see how a two-dimensional universe might work. It started with a design question of how a two-dimensional lock might work, and went on to strip tectonics, string that can't tangle, anatomy with zipper-like structures because tubes would break the creature apart, and on and on.
It was seeing those animated images of a tesseract that made me realise that time is just the fourth dimension, and that we're just four dimensional beings, which is why we can't directly observe time.
My theory is this one: If an x amount of dimensions exist, then an x-1 dimensional object or an x-1 reality cannot exist. Let me illlustrate that: A plane in math is in fact non existant, because its thickness is zero. Imagine a sheet of paper. Shrink its thickness to 0.01mm, then 0.001mm, then to 0.0001mm. But if you shrink it to 0mm, it basically disappeared, so a mathematical plane is in fact non existant. Now imagine a 3D cube that exist for 0.1 seconds. It exists. But a cube that exists for 0 seconds does not exist. So lower dimensional objects or realities cannot exist within higher dimensional realities. And if there would be a higher dimensional reality, then basically, we are non existant, which obviously isn't the case. Having said that, there could still be higher dimensions, but in that case, we, in fact, also are higher dimensional beings than we notice. One of our dimensions then, could be extremely thin, so that we don't notice it. (In the same way that one might not notice the extra dimension of a thin sheet of paper.) And then, there might be beings with that dimension being not extremely thin, so that, to us, they appear having an extra dimension, but then, we have that extra dimension too, but we just didn't notice that, because of it being extremely thin. For the same reason, we cannot have a lower dimensional reality within our reality, because its thickness in one of our dimension would have to be 0, making it non existant. I come to the conclusion that in reality, there can only be one number of dimensions of spacetime. How many, I don't know. 4, 5, 6, 10, 11, 26 ? I don't know. And whatever that number is, that number must have some logic to it. Think about it.

Visualizing higher dimensions is difficult, but mathematically they work fine. 9:58: A tesseract is a 4D object that can be visualized as a cube from certain angles. 10:24: 🌌 The video discusses the concept of higher dimensions and how they affect gravity and other forces. 10:24: Higher dimensions can be represented as objects with equal radius in all directions or as compacted dimensions. 10:50: A tesseract or 4-Cube has eight cubes for its surface, similar to how a square has four lines. 11:36: Moving through higher dimensions can appear as teleportation or walking around hidden faces. 12:03: Using higher dimensions as shortcuts involves folding or drilling through space. 12:33: Gravity weakens faster in higher dimensions, making stable orbits difficult to achieve. 12:58: Minor perturbations have a greater impact on orbits in higher dimensions. 13:28: In higher dimensions, gravity and other forces weaken inverse to distance. 13:37: Radiating forces like gravity make it harder for objects to have stable orbits in higher dimensions. 13:48: 🌌 The video discusses the challenges of finding habitable 4D planets and how the physics and chemistry would be drastically different in such a universe. 13:48: Sunlight and heat transfer would be different in a 4D universe, making it harder for planets to be habitable over long periods. 14:09: Tiny changes in the core's density can significantly alter the brightness and lifetime of a star in our 3D universe. 14:35: A 4D universe would have even higher heat transfer rates and lower density for particle interactions. 15:03: The density of matter decreases exponentially as the universe expands into higher dimensions. 15:15: The limited time available for matter to clump and form planets and life in a spread-out universe hinders the development of spacefaring civilizations. 16:09: Chemistry in a 4D universe would be drastically different, with weaker electromagnetic bonds and unstable molecules. 16:35: Entering a 4D universe would likely result in instant death due to the drastic changes in physics and chemistry. 16:49: In a universe with stronger gravity, planets would collapse into black holes and stars would be short-lived and small. 17:31: 🌌 The video discusses the possibility of living in a 4D universe and the concept of Boltzmann Brains. 17:31: Living in a 4D universe is a possible alternative. 18:14: The odds of life evolving in different physical constants or dimensions are unknown. 18:27: 3D may be uniquely suited for life due to certain biological and engineering considerations. 18:57: The fine-tuning of physical constants only means our type of life would be impossible. 19:10: The concept of Boltzmann Brains is introduced. 19:38: The possibility of being a Boltzmann Brain or part of a larger dream is discussed. 19:54: Simple lifeforms popping into existence and evolving is more likely than large brains. 20:10: Switching between universes and the potential for intelligent minds or aliens is mentioned. 20:49: 🌌 The video discusses the possibility of a high-gravity universe and its implications. 20:49: A universe with a billion times the gravity of ours could consist mostly of black holes. 21:00: Black holes in this universe would have a larger size and longer lifespan. 21:58: Basic hydrogen atoms could be pairs of black holes in this universe. 22:26: Our universe might be a 3D slice of a 4D universe with its own existing objects. 22:55: Interactions between our universe and higher-dimensional universes are possible. 23:09: It might be possible to study and implant human or AI minds into higher-dimensional objects. 23:20: Colonizing higher-dimensional universes is a potential consideration. 23:47: The nature of time in higher-dimensional universes is uncertain. 24:15: 🚀 The speaker discusses the potential benefits of exploring higher dimensions and highlights the recent International Space Development Conference. 24:15: Higher dimensions offer new directions for exploration and utilization. 24:59: Aliens in higher dimensions have little reason to invade or colonize our dimension. 25:27: The speaker co-hosted the International Space Development Conference in Dallas. 25:39: Keysight World: Innovate is a virtual vision conference focused on future technologies. 26:06: The conference covers topics like 5G/6G, AI-controlled vehicles, non-terrestrial networks, and digital healthcare. 26:48: The speaker will poll the audience for episode ideas based on the conference presentations. 27:14: The Gerard K. O'Neill Space Settlement design contest showcased over 26,000 entries from around the world. 27:31: The Wernher Von Braun prize was awarded to Dr. Eric Smith for his work on the James Webb Telescope project. 27:55: 🎙 The host discusses upcoming events and invites viewers to get involved, while also mentioning his recent surgery. 27:55: The host mentions upcoming events by the NSS and invites viewers to message or email if they want to be involved. 28:20: The host mentions his recent nose and tongue surgery, stating that he sounds clearer now. 28:43: The host previews future episodes, including discussions on artificial afterlives, life in 2323 AD, and what Earth would be like if humanity disappeared. 29:08: The host mentions a Monthly Livestream Q&A on June 25th and a discussion on mining or refining materials on the Moon in July. 29:19: Viewers can support the show on Patreon and access ad-free episodes on the streaming service Nebula. Recap by Tammy AI
My personal intuition is that space is actually more than 3 dimensional, but the forces we interact with predominantly propogate in 3 dimensions, or maybe even it's the 3 dimensional components that keep things running. Maybe you have force carriers being spun about in multiple directiongs along multiple dimensions, which divides their attention so to speak. So things try to act in 1 dimension but are skewed about then try to act in 2 dimensions but are skewed about but a tad less, and then act in 3 dimensions, and there's considerably less skewing beyond the 3rd dimension, everything just kind of looks at each other and balances out, and the attemtpts to collapse to lower dimensionality reaches its equilibrium at 3 dimensions at most scales. So if a 4 dimensional object comrpised of particles which were enacting forces upon each other, came into our nearby space, those particles would be weakly mutually attracted or repulsed, but would be more strongly influenced by the nearby 3 dimensional arrangement. Thent he 3 dimensional arrangement would act strongly on the 4 dimensional arrangement while the 4 dimensional arrangment would act weakly upon the 3 dimensional arrangement. And while the 4D particle arrangement would knock particles in the 3D arrangement askew, the particles in the 4D arrangement would be pulled into alignment with the 3D arrangement far more intensely... This would ultimately result in the vast majority of the 3D particles remaining 3D particles while the 4D particles get realigned into 3D particles, unless the 4D structure is constructed sturdy enough to resist collapse. Such a dimensional collapse would probably be a very violent event because the density of the particles will be exponentially increasing while the intensity of the mutually acting forces would also be increasing. (Incidentally, Stable extradimensional particles, are what I think dark matter might be Perhaps other stable 3 dimensional arrangements existing in the dimensions beyond the 3rd tugging on us gravitationally because the 3D mutual alignment of all particles and their interactive forces are not aligned absolutely perfectly, just close enough to be essentially stable. While alternate 3D arrangements are also not perfectly aligned, but are stable, and this works such that things might tug on us from beyond the 3rd dimension but will be felt far weaker, and will only practically influence the 3 dimensions in which our acessible particles are arranged, and we act likewise to them... So our Plane of existence has dark matter, but we're the dark matter of other planes of existence.) TL;DR: Dimensionality is arbitrary, and we're in 3D because all known particles are to the best of our knowledge in a 3D arrangement, and this is why forces also propagate in 3D; however, The conflict between infinite dimensionality and particles seeking 1-Dimensionality, at most scales, or it at least in the circumstances of our universe's creation/formation, finds its equilibrium in 3 dimensions leading to most stable fields of existence being 3 dimensional arrangements. Furthermore, Nth dimensional arrangements beyond 3 dimensions will shock themselves into alignment with the 3 dimensional arrangements they interact with causing hyperdensification of particles, forces, and energy, as they collapse into 3D; meanwhile other stable arrangements in 3 dimensions beyond the 3rd dimension of our arrangment will be unable to meaningfully interact with one another for the most part, but the minute interactions might have massive additive effects on the [hyper]cosmic scale, and that's one potential candidate for dark matter. (In the event that this entire schema isn't total bollucks.) TL;DR of TL;DR: I strongly and irrationally believe that we are in more than 3 Dimensions, but we percieve them as 3 Dimensions because matter arranges at it's most stable in 3 dimensions. And force propagation in 3 Dimensions emerges from the 3 Dimensional arrangement of matter and energy, not the other way around.
As someone who randomly plays your old videos, I can definitely hear a difference between your current voice and your previous one from ywars ago, but honestly I did not clock a difference within this video. Either way hope the speech therapy goes well for you Isaac!
Does anybody else remember a BBC miniseries from the late 1990s titled Invasion Earth? It involved Humanity's attempts to deal with an incursion by aliens dubbed nDimensionals or nDs for short. Very good series, though the ending was a bit of a downer.
I’ve never heard of it, but It looks like it’s on RUclips. I’ll have to watch it sometime, though I usually have way more things to read or watch than I possibly could keep up with haha.
Inconsiderate Aliens would a really good one. You know, the ones that always just drop by to borrow a few kilos of Phosphorus and purge their waste tanks in your upper atmosphere.
I love all your shows. If my book works, I will credit you for inspiring me to come up with another equal-but-different evolved species in our own outer solar system. The scifi story grows, but will take time and of course may not fly at all. There are already a few good stories about other life in our solar system. Anyway, keep it coming.
You do indeed sound clearer. But I don't know if thats the surgery or just changes in recording conditions. The clarity difference is very reminiscent of microphone quality/recording environment changes.
Well this rabbit hole totally isn't going to melt my brain Trying to wrap my head around now this would all work. But just like the immaterium from 40K,it's a good pain.
Isaac, I had a teacher like you in high school. After a semester of his lectures (and I've been watching your channel for years), I don't even notice it anymore. Keep doing what you're doing, Ad Astra!
Thanks Richard!
Seconded
Also the work put in definitely shows! As a fairly new subscriber who has blown through all episodes!!
Ad Aspera.
Notice what? His speech impediment? If you're trying to compliment him by telling him you don't notice his speech inefficiencies that's a ridiculous compliment. I actually enjoy the speech impediment, like the way his says "paper" very unique voice to carry very unique information, and there is no ignoring it. That would be like trying to ignore a strong French accent and saying " I don't even notice anymore."
Arthur video is amazing. Please never change your format to conform to the algorithm. It’s the perfect blend of science and science fiction. The videos are just long enough to explore a concept with adequate details or possibilities too make me think. I’m also a huge fan of your longer videos.
I appreciate your respect for axioms even when you don't hold them yourself, and considering them in earnest. You explain what physics and faith actually are quite successfully while taking into consideration they deal with different things. Thanks for your work
As an old science , civil engineering retiree I put natural science and theoligical to scientific and etomoligy translations. Thence applying physics of energy and mass to comparitives of theoligicals .
Interestingly, quantum entanglements and natural classical sciences of knowns formed an interesting parrallell including all historics to plausable energy forms and especially when combined with matter forms within human detection to which jibed to more than swamp gas and auroras !
At least in the 3rd Dimension we can convey feelings like Love, Happiness, and Sadness on a physical level-- nothing is better than touch.
As an infinite being, you can't touch anything because you are Absolute and are everything.
@@MilitaryMatters1bs, touching yourself will always be a thing 😤
@@MilitaryMatters1mushrooms and you become the universe touching itself
I enjoyed the Dark Forest strategies outlned in the Three Body Problem series. There used to be 10 dimensions, but every now and then some species somewhere would invoke a dimensional strike that entirely disabled an entire dimension, leaving us with the three we know of and reducing the speed of light to what it is now. A species would learn to adapt to life in lower dimensions and strike one off, knowing that other species couldn't survive the transition. Like the Singer targeting our solar system as ground zero for an ever-expanding reduction to two dimensional universe. The description of the transition as the borders of 2D space expanded to consume literally everything and map it all on a paper-like plane was fun to imagine
I was visualizing the opposite as I read. The whole 3D universe being shrunk to fit on an infinite plane. It would kill everything in the universe except what was already existing on the plane. Eerie
Well, we should have used the slow fog and figured out the black domain since it was spelt out for us in those tales but alas Ye Wenjie doomed us regardless with so many hunters lurking it was inevitable. But glad you had fun, this was only time I shudder at the thought of concentric circles 😂
I thought 1 and 2 d space were conceptual only as they cannot exist independently as nothing can have any substance without a third and fourth dimension , the fourth being time to enable actions .
I think you're leaving out a couple of things. Dimensional bombs would reduce the dimension of an area, and the effect would spread and could not be stopped. The universe as we see now is a result of that effect spreading so far and reducing the dimensions from 10 to 3, leaving some pockets of 4-D. But the effect doesn't stop there either. As time goes on, our 3 dimensional life will continue to reduce to 2, and we would die with that.
@@ShadeSlayer1911 Yep, and some time later, Singer's species would die too, as life in 2D is impossible, which makes the whole story moot.
I love all the episodes on this channel, but I especially love the more occasional out there ones. I’d like to imagine the idea of two civilizations communicating in different dimensions by making sculptures of themselves in the other’s dimensions. To the higher one, the lower would look like a stick figure on paper, and to the lower it would be some semi- incomprehensible shape. Maybe not possible but it would be an interesting first contact!
People already do feel that all the time. It's called DMT
You've finally made me "get" the concept of compactified higher dimensions. Thanks, Isaac, you really are a wizard.
I can only assume that means you now understand that they can't exist.
Greg Egan's _Diaspora_ has the colonization of a higher dimensional universe as one of its plot points. It's amazing how singular he is in incorporating such far-out ideas into his fiction, I feel like so many of the concepts in further-afield episodes such as civilizations at the end of time or false vacuum decay have only been touched by his works. Wish there were more of him.
I knew I couldn't be the only one thinking of that story off-and-on through most of this episode!
Fantastic book and possibly my most re read . Schilds ladder another blinder too . The book gives future exploration a whole new dimension lol . Yatima right to the end and back to the coal face ! wow.
The best sense of wonder novel I've read.
@@MyKharli I'll be honest, I think it kinda falls apart at the ending, like Egan _really_ wanted the ending to be Yatima alone doing math but the plot forced Yatima & Paolo together.
It (and _Schild's Ladder_ as well as his classic _Permutation City)_ still legitimately blew my mind when I read it, and I consider them peerless when it comes to concept novels. Special mention goes to the Wang's Carpets chapter, another vertigo-inducing what-if.
@@Low_commotion It was an amazing journey !..in all those books and they live daily in my imagination .
My favorite version of higher dimensional aliens is the Orz from Star Control 2, mostly because you never get a full, accurate translation matrix for their language and so their dialogue is full of "best fits".
The weirder thing is that BOTH higher and lower energy aliens were introduced in Star Control 2 (the Ariloulaleelay and Orz, respectively). The Orz are notable because they actually inject a conscientiousness into our universe, completely replacing the Androsynth in a form of Fermi Paradox. Because they are essentially Cthulhu, incredibly badass, and creepy. And when you visit the Ariloulaleelay in their own dimension, the X/Y coordinate system makes very little sense.
That game is such a masterpiece.
Thanks for making my topic suggestion into a full episode! It's always interesting to see where you take an idea in comparison to what I imagined.
Just study the paranormal. Extra dimensional beings is one of the leading theories for what's going on on Earth

Good stuff, my friend. I could tune in and listen all day long. Very informative!
First time I’ve heard discussed something I’ve wondered about with regard to higher dimensions: whether there are more than just one dimension of time. I’ve always wondered whether multiple time dimensions (woven together in our normal experience of ‘time’) could resolve to unravel time-travel paradoxes and the speed-of-information limit.
Thanks for broaching this topic, and please consider a deeper dive into theories of time for a future episode.
I alway thought that the random nature of quantum decay could reflect that the universe has another time dimension and that the decay might make sense seen from another time dimension.
You could have one time dimension that works normally being unable to move in any direction in it but forwards, and then another time dimension that you more typically experience and that can be travelled around in.
So instead of the grandfather paradox you are constantly moving forwards in time dimension two, but in time dimension one you went back in time and killed your grandfather but you still exist.
Tachyons have 3 time dimensions and 1 space dimension, basically they use "our" space like we would with "their" time
@@atashgallagher5139that’s a cool idea. It makes sense too. It’s kinda the same as our big bang being part of a larger multiverse. In this senario Our time is just part of a much large(or infinite) multiverse of times.

I can understand why you would want to modify your speech, but I must confess I had no problem understanding you before. It was what made you an individual and very distinct. I grew up with a sister who had a speech impediment and maybe that is why it isn't an issue with me. Best wishes to you Mr. Arthur.
Perhaps the idea of a multiverse or quantum-universe where "everything that can happen does happen" is really just how we experience existing restricted within a single "slice" of a higher-dimensional reality. It might even explain quantum entanglement, since starting in a particular "slice" of something would necessarily make another particle correspond appropriately.
It would be difficult to discern the difference between alien entities that are interdimensional from entities that use other dimensions to travel and communicate. To us both would appear to be interdimensional.
Thank you! I love the way you explain things, I sort of get it sometimes. You’re much appreciated.
Hey, I wasn't expecting this episode, what a great day!
Yay! Sci-fi Sunday! I needed this
Isaac, I've been following your videos for years, except the past year when so much was going on in my life that I had a hiatus.
I'm happy to come back and see you are doing as well as ever, or better. You're work is incredibly inspiring to me, and for the looks of it, I'm not alone on this.
Thanks. Wishing all the best for you and your family.
Hey Isaac, this video reminded me of what the caller in the 1997 Art Bell radiostation incident said. With him claiming that aliens have access to more dimensions than us.
The idea of extra-dimentional aliens sounds bogus but it’s an interesting expansion on the whole concept. It would kind of explain the whole “aircraft moving in ways that defy our current understanding of physics” thing, with them also poking in and out of our reality at will XD
It sounds like history channel levels of delusional but it’s growing on me
It's not delusional. He's explaining a concept. He's not saying it's correct.
"Okay, um, um, okay
What we're thinking of as, as aliens
They're extradimensional beings
That, an earlier precursor of the, um, space program they made contact with
They are not what they claim to be
Uh, they've infiltrated a, a lot of aspects of, of, of the military establishment
Particularly the Area 51"
Been waiting so long for this episode! Thanks Isaac!
don't forget "A wrinkle in time" for Tesseract fame! That's how I first heard of it! also i am in awe of the guy that went through so much effort to make a suit out of the thumbnail art of your channel!!!
Incredible! The differences in orbital gravity between dimensions could very well explain why they crash so often on earth! This is insane
I think the most interesting take on higher dimension aliens is the Law of One series. I have for years studied fringe religions, and treat every single one as agnositically and respectfully as I can. I hope I dont mess it up to much or get too much wrong but as I remember Law of One is one where people believe that our souls grow and become greater, eventually moving up dimensions can inhabit higher dimensional bodies. I think at like 5th dimension they believe you shed needing to inhabit a body completely and exist as a light being that can interact with lower dimensions. This is where we get like gods, angels, demons, and stuff. Most notably they believe Ra (the very same Egyptian god) is one of these higher density light beings which has taken an interest (among other high dimensional beings) in seeing humans throgh to the 4th dimension. It's a really interesting read and tbh I honestly believe it's one of those religions that sounds super wild, but the message is super good and peaceful.
Thanks Issac and Mrs Isaac, much appreciated.
This can be my go-to way of answering Fermi Paradox

Hope you've recovered/are recovering well from surgery, the bit at the end does sound a wee bit clearer for me, since you asked. Thanks for making interesting videos :)
I loved science fiction comics as a kid, i remember well a story that scared me and fascinated me at the same time. It was about a odd family that drew too much attention to themselves and it was dimension hopping "aliens" my theory was they might have humans that lived under so different conditions that they didn't look human. That was my first thought about alternate dimensions. And what they might be like.
Favourite channel for gentle mind stretches at the end of a long day 😌😌 Don't buy into extra physical dimensions myself. Though I think different scales, in time and space, are super interesting.
(Rational animations) made a video called (that alien message) that tackles a lot of the topics near the end of this video about colonising higher dimensions.
I was hoping you would take on multiple time dimensions. Greg Egan’s take on them was very interesting but I want to hear more.
This martial approach makes it very clear why intelligent beings are observing us and not trying to make contact. They must be concluding "another failed attempt here"...
At first glance I thought this episode said, higher delusional aliens. I was a little disappointed when I realized it was not about delusional aliens.
Main line this right to my brain...makes my brain happy. Talking on reality vs trying to fit it thu the lens of some ego. Give me the real stuff everytime.
For some reason I feel like this man is hunting rabbits
Really giving "Taking life in a whole new direction" a very literal whole new meaning there I see.
TY SFIA! I try to think of dimensions as degrees of freedom. x,y,z is three. t is 4. 5 and above are just more degrees of freedom (c, l, r, m, delta, gamma, theta, omega, etc.) We live in a universe that has as many dimensions as we have letters from 3 alphabets to describe and observe.
Also Kevin Bacon 😀
@@djschultz1970all the dimensions somehow come back to him 😂😂😂
I can't help but wonder how well our stereoscopic vision could interpret a 4d object. I feel our brains could adapt to whatever they experience. But could we actually experience a 4d object with the senses we have?
that is a very interesting question, as even the fundamental lens focusing light onto the retina will drastically be affected by how the eye shape is translated into the higher dimensions. the ability to determine up/down left/right and depth may be drastically reduced or exaggerated, and the ability to determine a 4 dimension may end up mixed in as XYZ or replace one of them while XYZ gets flattened to XY, or some mix of time perception, or gifted with 4+ dimension sight, so many ways that can go. As far as mentally adapting, I do agree that it is possible as any computer can calculate more than 3 dimensions with some work (that has been done already for some things).
oh, and then I have the thought, does light even propagate along the extra dimension, hmm (shrugs). maybe it's something like how the shadows (or whatever) cast in the 4th dimension are seen in the other 3.
It's a great question. I don't the answers obviously but my inution is that we'd briefly notice something odd then our brains correct it. Kind of how peripheral vision works.
@Zarcondeegrissom I could be wrong on this but as I understand it, light would not propagate through higher dimensions since our math for intensity (that's the Wattage per area) only make correct predictions when we assume light spreads out as a sphere. Not a circle, line, or hypersphere.
Likewise there are some elements of higher level physics which work the other way: the only way to make an equation work is to assume dispersion across higher dimensions. I believe this is a (very broad) reason why M-theory requires 11 dimensions to work correctly
Edit: literally just started watching and Isaac said like half of this lol. My b
I've wondered about this as well. I agree with what you say about our brains, but our eyes are physically 3D. So, I though about what a 2D creature might see in our world and I realized that his 2D eyes can only see 1D images. If he has at least two 1D eyes, his brain could form an idea what 2D looked like, but in a 3D world, he would still only ever be able to see a slice of 3D that was "in the plane of his 2D body" He would see whichever slice of objects he was pointing at. If he is rotating in 3D, then the things that he sees are shifting in strange ways as the plane of his perception swept around. I think that is what we would see in a 4th dimension - we could see shapes and surfaces, but they would all look like constantly shifting 3D objects to us. We might see a large globe with 5 smaller globes floating around it and not understand that this was a 4-dimensional "hand" and 5 "fingers" of a 4D being, because we are only seeing part of it.

You can embed flat 3D space on the surface of a 6-cube, with 64 flat cubic volumes with 192 vertices (singularities), although intrinsically it is a flat 3D torus looking like a 4x4x4 matrix of cubes where leaving one side re-enters the opposite sides.

Pack up, we're moving.
Greenwich village?
Better a place orthogonal to all you see, but don't forget the sleeper couch.
the problem with moving between dimensions would be critically dependent on subatomic particles.
The quarks of our dimension evolved 3 different generations of particles with the same chirality, spin and charge.
Only differing in their intensity.
Doubtless a different dimension with an extra number of dimensions or different properties than ours would have quarks that have more generations, or force carriers which don't exist in our universe. This would change how atomic mechanics work, and affect how chemistry works.
Maybe they have something better than oxygen and carbon for life to construct molecules with.
BTW Tesseracts probably entered public consciousness with Madeline L'Engle's Wrinkle in Time series.

If true, would maybe mean we have evidence of type 1, type 2, or even type 3 civilizations. 1 of the vehicles was described as being much bigger on the inside. Able to rearrange space/time. Exciting times ahead if true, lets hope everything is disclosed and released along w/ all recovered technology. Could be pretty epic to leap-frog our civilization by 500 years or more.
In the series Dune, the goal of the Bene Gesserit breeding program, the Kwisatz Hadersch, is a being that can perceive more than 3 spacial dimensions.

Great video , hope there's many more to come😎
@12:58 not necessarily, we don't know this for sure as we don't have any way of testing this. In regard to the perturbations, there's no reason to think that if gravity scaled with dimensions, the other forces acting on orbits (such as the speedup) wouldn't increase as well, balancing everything out.
All the people here whining about issac arthurs voice should shut up and be more respectful he has a lisp and cant help it at least he takes the time ro amke quality videos for us to all watch instead of complaing or making fun of his lisp dont watch his videos than if you think you can do better than him by all means show us ...and also some ppl mentioned to use AI voice overs well those suck
Where is he from?
Several years ago I left my body and saw a linear drawing before me. I'd never seen anything like it before. I hurriedly returned to my body and sat at my desk in an attempt to replicate what I had seen on paper. I couldn't do it. There simply wasn't enough room. i.e., enough "space" to do so. I needed another dimension. Will never forget it.
"“…every figure of space is but the result of the intersection by a plane of some corresponding figure of one more dimension - as a square is cut from a cube or a circle from a sphere. The cube and sphere, of three dimensions, are thus cut from corresponding forms of four dimensions that men know only through guesses and dreams; and these in turn are cut from forms of five dimensions, and so on up to the dizzy and reachless heights of archetypal infinity.” Through the Gates of the Silver Key

Regarding the 2D life, if someone has any issues understanding the concept, I highly recommend Tibees' short videos where she discusses stealing from 2D beings, very visual and intuitive explanation of how dimensions interact.

The last time I was this early hot air balloons were high tech.
honestly that is the biggest end all to high dimensional entitys.
HOW TO GET THERE and vice versa as you said and its likely never gonna be a actual "gateway" or any physical doorway more like a IRL exploit where you do a specific combination at certain times and "leave the map"
That's utterly retarded. Reaching a four or five-dimensional plane is not like doing a ritual and going to some magical world, no, it's just a higher physical plane where native 4D beings reside

That’s why you don’t get to heaven hell through a portal, unlike as seen in doom or 40k, you get there by dying, which is when your immaterial component disassociates from your material component and is able to go to immaterial-only realms
@@cosmictreason2242 yep its ironic in a way that science actually gives more clear methods to describe abstract concepts like afterlife realms.
even if science at its nature is outright opposed to the supernatural at certain levels of understanding the diffrence becomes null and void.
clarkism or clarketech is how i think thats often refered too.
Surprised you didn't touch on dark matter in this episode. It seems like it could fit there given the interaction seems to be limited to gravity. Also black holes could have some aspect of an extra dimension since normal physics break down within them.
I have a question, how does the 3d world look from the higher dimension spitial dimensions? Do 4D aliens also go blind if they stare at the sun for too long? Does the sun have a 4d component(i dont mean time when i say 4d but rather extra spatial components)
So wie Bücher in einem Regal? wobei jede Realität bereits geschrieben wurde.
I also want too say, I feel dreams are extra dimensional. I don't know howmany times I have been dreaming and as I'm waking up my understanding of what it was about fades away. It's the weirdest feeling.
@Bleys1973 I totally feel this too! Like right after waking up, I’m thinking in detail about the dream, then 30-60 minutes later, I’ve totally forgotten the details. The fact that I even thought about it or dreamt it in the first place so recently feels rather foreign and out-there. It’s very odd.
As far as I'm concerned, dreams are just running DEFRAG on your hard drive and getting a glimpse of the data as it's being moved. If you had something like Johnny Mnemonic's brain-drive, then you could probably see the data you were carrying when dreaming, even if it didn't show up when awake.
Don't neglect the contributions of Flatterland, An Episode of Flatland, and The Planiverse!
Im going to invade a 2 dimension realm ........with my pencil........
i believe extra dimensions are much larger, not smaller. in some cases we r like a plank length to other dimension realities. this takes multiverses to the level of superverses...we r within superverses and not adjacent to multiverses.
one of the reasons I like the new for you tab is cause I get to find interesting videos like this.
I'd like to recommend the book, Death's End by Cixin Liu (sequel to The Three Body Problem and The Dark Forest). No spoilers, but it's incredibly topical.
I usually understand a little of what you discuss, but this is so far beyond my comprehension it made my brain hurt.
Ah, a subject that is dear to my heart! (My avatar is a 6D Hypercube) 😁 Anyway, may I also recommend the book "The Planiverse" by A.K.Dewdney - a very enjoyable book that talks about 2-dimensional life and goes into a lot of detail about how it might work. 😄
@WildStar2002 If you’re aware, could you explain the details of your avatar?
@@stormstaunch6692 It is a still from an animation I did called "Tour 6D" where I start from a single point, transition to a line, then a square, cube, tesseract, 5D hypercube, and then 6D hypercube - and then back down to a point.
@@WildStar2002 What exactly is a tesseract, 5D hypercube, and 6D hypercube?
@@stormstaunch6692 They are all higher-dimension geometric objects. They share a similarity in that each one of them can be 'stacked' or 'tiled' to fill all of space - depending on the dimension.
So, start with a single point or vertex. It has no dimensions, so it is considered a 0-dimensional object. To make it into a 1D object, a line, you must make a copy of the point some distance away (1 unit for simplicity), and then fill in the area between. A line is the only kind of 1D object you can make. It has two vertices and of course the line itself. You can stack lines next to each other to fill all of 1D space. There is no need for this in 0 dimensions, because all you can fit in there is that single point.
Next, 2D. If you make a copy of that line at a right angle to the single dimension that is there already - let's call that length, so we are adding width - then connect those two objects together, we get a square. 4 points, 4 lines, and 1 square. You can make a grid to fill all of 2D space, each square acting like a pixel on a computer screen or a box on grid paper. Next, make a copy of that square and move it 1 unit distance away from the original at right angles to both the width and length dimensions - height - fill in the space between and we have a familiar cube. 8 points, 12 edges, 6 square faces, and 1 cube. Again, all of 3D space can be filled with a grid of cubes - voxels are the 3D equivalent of pixels. We can also start to see some patterns that help figure out what might come next in this progression. Every next higher dimensional square/cubic object is formed from 2 X the current dimension 'faces' of the next lower dimension. A 3D cube has six square faces. a 2D square has 4 line 'faces'. A 1D line has 2 point 'faces'. So, a 4D cube should have eight cubic 'faces' and that is correct. There is a simple formula to figure out all of this stuff, since we are making a copy of an object, projecting at right angles to all the dimensions that contain it, and then filling in the gaps. If m is the number of faces, edges, or whatever in an object and n is the number of the next lower dimensional parts then to find the next higher dimensional equivalent it is new m = 2 X m + n. I know that's a bit confusing, so an example: to mathematically figure out what a cube would be from a square, start with the points of a square. m = 4, since there are 4 points and n = 0, since there is nothing below a point in dimensions. So, 2 X 4 + 0 = 8 points in a cube. Next the lines: m = 4 (lines in a square) and n = 4 (points in a square), so a cube has 2 X 4 + 4 = 12 lines (edges). For squares (faces), m = 1 from the square, and n = 4 lines (edges), so a cube has 6 faces = 2 X 1 + 4. The cube contains one cube, obviously, but this also works mathematically: m = 0 cubes in a square and n = 1 square in a square; 2 X 0 + 1 = 1 cube in a cube.
This pattern continues as high as you would like to go. Also consider that it is valid to call a square a 2D cube, or to call a line a 1D cube, a point a 0D cube, or you could even call a cube a 3D square, etc. The next step is pretty easy mathematically, but the problem is I cannot show you what a 4D cube (also called a hypercube, or a 4D hypercube, or a tesseract, as well as a few other names) looks like because we are all hopelessly mired in 3D space (not counting the temporal dimension of time). We can describe a tesseract, project what it's shadow would look like in 3D space (like what a cube's shadow would look like on a flat projector screen) but we can't *see* a tesseract in the same way we can 3D and lower dimensional objects. All that being said, running the same formula again, a tesseract has 2 X 8 + 0 = 16 points, 2 X 12 + 8 = 32 edges (lines), 2 X 6 + 12 = 24 square faces, 2 X 1 + 6 = 8 cubic 'faces' (also called cells), and 2 X 0 + 1 = 1 tesseract.
The pattern continues in five dimensions. This object is called a 5-cube, 5D hypercube, pentaract, and other names. It consists of 32 vertices, 80 edges, 80 square faces, 40 cubic cells, 10 tesseract 4-faces, and itself - the 1 pentaract. A six-dimension hypercube, 6-cube, or hexaract would have 64 vertices, 192 edges, 240 square faces, 160 cubic cells, 60 tesseract 4-faces, and 12 5-cube 5-faces, and the hexaract itself, of course.
Whew! All of that with a little bit of math and a lot of intuition, analogy (from lower dimensional analogs), and the genius of the mathematicians who first conceived of these objects, like Ludwig Schläfli, Harold Coxeter, Eugene Dynkin, Jonathan Bowers, and George Olshevsky. Fascinating stuff!
@@WildStar2002 okay but what about a 1000D cube 🥴
Been waiting for this one!
What are your thoughts on Kozyrev's mirror??
i read some speculation that adding another spatial dimension would likey add another electron shell to atoms which would totally rewrite the periodic table.
Yes, we also could expect a higher number of stable atoms if the strong force works similarly, you could fit more nucleons in the same area
I forgot that a new Sci-Fi Sunday episode was coming out.
A most welcome and informative weekend treat Isaac.
Your voice does sound clearer but it's hard to quantify what exactly has changed.
_The Planiverse_ by Dewdney is an expansion of the ideas from _Flatland_ to see how a two-dimensional universe might work. It started with a design question of how a two-dimensional lock might work, and went on to strip tectonics, string that can't tangle, anatomy with zipper-like structures because tubes would break the creature apart, and on and on.
Also "Flatterland" & "Sphereland"
It was seeing those animated images of a tesseract that made me realise that time is just the fourth dimension, and that we're just four dimensional beings, which is why we can't directly observe time.
Yes I noticed a difference! Sounds great!
My theory is this one: If an x amount of dimensions exist, then an x-1 dimensional object or an x-1 reality cannot exist.
Let me illlustrate that: A plane in math is in fact non existant, because its thickness is zero. Imagine a sheet of paper. Shrink its thickness to 0.01mm, then 0.001mm, then to 0.0001mm. But if you shrink it to 0mm, it basically disappeared, so a mathematical plane is in fact non existant.
Now imagine a 3D cube that exist for 0.1 seconds. It exists. But a cube that exists for 0 seconds does not exist.
So lower dimensional objects or realities cannot exist within higher dimensional realities.
And if there would be a higher dimensional reality, then basically, we are non existant, which obviously isn't the case.
Having said that, there could still be higher dimensions, but in that case, we, in fact, also are higher dimensional beings than we notice. One of our dimensions then, could be extremely thin, so that we don't notice it. (In the same way that one might not notice the extra dimension of a thin sheet of paper.)
And then, there might be beings with that dimension being not extremely thin, so that, to us, they appear having an extra dimension, but then, we have that extra dimension too, but we just didn't notice that, because of it being extremely thin.
For the same reason, we cannot have a lower dimensional reality within our reality, because its thickness in one of our dimension would have to be 0, making it non existant.
I come to the conclusion that in reality, there can only be one number of dimensions of spacetime. How many, I don't know. 4, 5, 6, 10, 11, 26 ? I don't know.
And whatever that number is, that number must have some logic to it.
Think about it.

Recap by Tammy AI
My personal intuition is that space is actually more than 3 dimensional, but the forces we interact with predominantly propogate in 3 dimensions, or maybe even it's the 3 dimensional components that keep things running. Maybe you have force carriers being spun about in multiple directiongs along multiple dimensions, which divides their attention so to speak. So things try to act in 1 dimension but are skewed about then try to act in 2 dimensions but are skewed about but a tad less, and then act in 3 dimensions, and there's considerably less skewing beyond the 3rd dimension, everything just kind of looks at each other and balances out, and the attemtpts to collapse to lower dimensionality reaches its equilibrium at 3 dimensions at most scales. So if a 4 dimensional object comrpised of particles which were enacting forces upon each other, came into our nearby space, those particles would be weakly mutually attracted or repulsed, but would be more strongly influenced by the nearby 3 dimensional arrangement. Thent he 3 dimensional arrangement would act strongly on the 4 dimensional arrangement while the 4 dimensional arrangment would act weakly upon the 3 dimensional arrangement. And while the 4D particle arrangement would knock particles in the 3D arrangement askew, the particles in the 4D arrangement would be pulled into alignment with the 3D arrangement far more intensely... This would ultimately result in the vast majority of the 3D particles remaining 3D particles while the 4D particles get realigned into 3D particles, unless the 4D structure is constructed sturdy enough to resist collapse. Such a dimensional collapse would probably be a very violent event because the density of the particles will be exponentially increasing while the intensity of the mutually acting forces would also be increasing. (Incidentally, Stable extradimensional particles, are what I think dark matter might be Perhaps other stable 3 dimensional arrangements existing in the dimensions beyond the 3rd tugging on us gravitationally because the 3D mutual alignment of all particles and their interactive forces are not aligned absolutely perfectly, just close enough to be essentially stable. While alternate 3D arrangements are also not perfectly aligned, but are stable, and this works such that things might tug on us from beyond the 3rd dimension but will be felt far weaker, and will only practically influence the 3 dimensions in which our acessible particles are arranged, and we act likewise to them... So our Plane of existence has dark matter, but we're the dark matter of other planes of existence.)
TL;DR: Dimensionality is arbitrary, and we're in 3D because all known particles are to the best of our knowledge in a 3D arrangement, and this is why forces also propagate in 3D; however, The conflict between infinite dimensionality and particles seeking 1-Dimensionality, at most scales, or it at least in the circumstances of our universe's creation/formation, finds its equilibrium in 3 dimensions leading to most stable fields of existence being 3 dimensional arrangements. Furthermore, Nth dimensional arrangements beyond 3 dimensions will shock themselves into alignment with the 3 dimensional arrangements they interact with causing hyperdensification of particles, forces, and energy, as they collapse into 3D; meanwhile other stable arrangements in 3 dimensions beyond the 3rd dimension of our arrangment will be unable to meaningfully interact with one another for the most part, but the minute interactions might have massive additive effects on the [hyper]cosmic scale, and that's one potential candidate for dark matter. (In the event that this entire schema isn't total bollucks.)
TL;DR of TL;DR: I strongly and irrationally believe that we are in more than 3 Dimensions, but we percieve them as 3 Dimensions because matter arranges at it's most stable in 3 dimensions. And force propagation in 3 Dimensions emerges from the 3 Dimensional arrangement of matter and energy, not the other way around.
16:03 @Isaac Arthur Goldilocks zone is just right *for humans* yes. I find that term to be a bit misleading.
As someone who randomly plays your old videos, I can definitely hear a difference between your current voice and your previous one from ywars ago, but honestly I did not clock a difference within this video. Either way hope the speech therapy goes well for you Isaac!
Does anybody else remember a BBC miniseries from the late 1990s titled Invasion Earth? It involved Humanity's attempts to deal with an incursion by aliens dubbed nDimensionals or nDs for short. Very good series, though the ending was a bit of a downer.
I’ve never heard of it, but It looks like it’s on RUclips. I’ll have to watch it sometime, though I usually have way more things to read or watch than I possibly could keep up with haha.

Well this rabbit hole totally isn't going to melt my brain Trying to wrap my head around now this would all work.
But just like the immaterium from 40K,it's a good pain.
