If higher dimensions exist, they aren't what you think | Exploring Worlds Beyond Our Own 

I remember in high school asking my physics teacher was exactly caused gravity and she looked at me like I was an idiot. Her explanation was that gravity just existed. It's probably silly, but that moment of having my curiosity shamed in front of the whole class steered me from science fields. As a kid I was so in love with space but after high school I ended up feeling like an idiot and went into the fields I was praised for in school. Now I'm in my mid 20s, lots of college debt, in a industry I hate, but have rediscovered my love for science. I'm hoping to go back to school soon to study engineering. Not sure why I typed all this, but I really enjoy these videos.

5D beings be like: lmao look at them trying to understand basic shit

Your Flatland animation is one of the best I've seen. It's not often portrayed at different angles, but you nailed it. And the way you make it easy for the layman to understand is impeccable. Awesome video.

so the flat earthers are 2D beings. That kinda explains their point and their insistence.

We're flatlanders in the time dimension; only capable of seeing an infinitesimally small slither called the NOW

Me high asf : "this is good"

I spent the majority of my life as a fabricator by profession. As such, one has to learn not just the materials go into a project but the correct measurement of them. Applying that knowledge to string theory tells me that there more 'materials' involved that we are aware of much less how the fit and work together. Just my two cents.

Some could be interdimensional... if a 3d person touched a 2d livingscape with the tip of their finger, then the 2d person would perceive the tip of the finger as an expanding and contracting colored/textured circle upon contact of the 3rd dimensional person. Yet the 2d observer does not see that there's a 3d person behind the tip of their finger making contact. But the 3d person can see the entirety of the 2d persons present existence before them from the outside. Same can be said with making contact with an interdimensional entity who had expressed contact with you. The shifting and complexity observed from some of these "living crafts" or "orbs" could have been akin to what a tesseract is to a cube. A tessaract is a hyperdimensional cube, that's essentially a cube within a cube that's in continuous motion. An interaction across dimensions creates bizarre phenomena since the conversion from one to another dimensions is limited to the perspective of the observer from the "lower perceiving" dimension. Queue subjective consciousness overlaying the objective reality of the infinite as our personal experience... So behind that evershifting display observed, perhaps was just the tip of what the "higher perceiving" entity actually was. Also in other dimensions the laws of physics and rules of chemistry may be exotic to our known systems of knowledge contained to our reality. So interdimensional beings to us may appear partially visible, as well as chemically composed of entirely exotic elements to our reality which may behave differently from within our reality than it does theirs, perhaps allowing for law breaking physics and gravitational, temporal, you name it phenomena to be displayed. Even then, what we observe may then be something entirely different due to the conversion of chemistry, physics, physicality within the observed interaction between our dimension and theirs. Maybe an element cannot exist within our dimension and so now our dimension has to convert this forbidden element into something with which to make sense of it within the confines of our dimension's set of physics which can lead to bizarre results. It boils down to finding common objective communication translated between realities, from each communicating party's subjective reality to establish a common mode of contact, to expand consciousness. Yet even then communication may still be totally intangible as consciousness from every dimension may be unsolvably exotic to one another due to an intelligence/comprehension gap. If I'm right then each dimension is actually a conglomerate of "servers" upon servers, compartmentalized as our own individual dimensions, which is likely derived from some sort of quantum computer experiencing consciousness of itself, through within itself, amongst itselves, to discern itself among all selves, after a point of singularity. There are levels to it. I realize I sound like a nut. I'm just trying to regurgitate my mind into words which is limiting. Food for thought... 💡

You are explaining a 4 D world... To a 3D creature.... On a 2D screen.... to my 1D Brain.....

I went to 4th dimensional space and now I’m left handed

I've always tried to imagine what the implications of a universe with 2 temporal dimensions would be. Although that doesn't seem any more possible than visualizing an actual 4-cube and not just a projection of one. Or even just 4 spatial axes all perpendicular to one another.

One way I like looking at it is that for a 4-th dimensional being (space and time) our past, present, future is all part of a big picture..while we only see parts of it as time passes. For us that being would indeed be Godlike.

Whenever I get too full of myself, bursting with egocentric vanity, I watch a video such as this, and realize that I am a blithering idiot. Thank you. I needed that.

One of the best videos I've ever seen on this topic. A real 15 minute gem.

You really have to respect and admire just how special and ahead of his time Einstein was. So many years later and some of his thoughts and discoveries are still blowing minds when they keep showing up, upon even more discoveries by others.

I am not religious to preface, but this beautifully intuitive description of how a fourth dimensional creature 'dips' into our world immediately made me think of those classic descriptions of horrifying angels, with tons of wings and eyes.

" All I know is ... I don't know. " Fred Sanford.

GREAT VIDEO, thanks Zach, great explanations, thanks for taking the extra time to show the various dimensions :-)

I've wondered about exactly this ever since I started understanding mathematics from a more abstract, pure point of view right around high school

This makes me think of how angels are described in religious drawings. The drawings of them are so wild because they come from a realm your mind can't completely process.

I'm trying hard to pretend I understand this.

This is one of the most interesting ways this concept has been presented

We see a 2d projection in our 3d world so the standard for 4d eyes is seeing a 3d projection. With a high level of echolocation, could one see a 3d projection of a 4d world and learn to understand it?

i love that i can go straight from listening to a terence mckenna mushroom trip to a science channel and hear all the sames things repeated

While going through a period of trying to understand time, I concluded that it was not a dimension parallel to the other 3, but rather a curved dimension or dimensions that were tangential to the 3 physical dimensions we occupy and which explained why we experienced time as the singular moments of intersection of the curved time dimensions with our physical dimensions. Further thought led me to realize that we are all going through time at slightly different speeds due to gravity and the special theory of relativity, and that it was hence more useful to think of the time dimension(s) as very small, as he speaks of them in this video--curled up and associated with different points in space, responding to the field of gravity they are in. I was excited to read that some physicists hold this theory, and look forward to reading more about them. Thank you, Zach!

The inversion concept help me understand Tenet so much more 👏

I don't understand 98.5% of what I'm watching here, but can't stop coming back. It's great, I love going from completely ignorant to slightly less ignorant! Thanks you for these accessible explanations, I appreciate the knowledge. 🙏

Nobody: Physicists flirting: "I'll take you to another dimension."

This is freaking amazing!!!!! You made it simple and I understand!!! Thank you!!!!!

I love your dedication, good luck buddy 😁

This video really improved my intuition of what higher dimensions could be like. I've heard the "ant on a cable" analogy but it wasn't easy to understand when I first heard it. Your explanation of the analogy, plus the example you made with inverting objects in higher dimensions, and your explanation of extended vs small/curled extra dimensions made a lot more sense. Best extra-dimension intuition video or explanation I've come across so far.

If there's one thing I love, it's mathbro talking about higher dimensions.

"from far enough away the cable looks like a line" - we need to understand this kind of thinking when we look at our universe. When we see that galaxies move in filaments throughout our universe we should take this as a jumping off point for new concepts through imagining new perspectives on what this means.

@7:00 if returned “flipped” to one’s 3D-world, the observer would be presented with a mirrored 3D universe; the observer wouldn’t have any perception of his heart or birthmarks mirroring.

Bosonic string theory is not often accepted anymore, and M-theory unites the 5 different superstring theories into a single unified theory. Right now, M-theory is the main theory for unifying the forces in higher dimensions. Superstring theories all arise from M-theory, so they are not really different theories.

"I think the universe is shaped like a donut" -Homer Simpson

Wow thank you for this video and explanation. It made some of these concepts really click for me for the first time. Especially the ant on a wire as it relates to the 4th spacial dimension. Thanks again!

tool on the speakers this on the visuals. epic doseage bro!

5:48 6:20 6:45 7:02 Imagine how painful it would be to be pulled into a world that you cannot enter. 7:17 Do mirrors just flip you in the 4th dimension? edit: its been 5 months why is this still popular

You explained an extremely complex thing to visualize in a very simple way. Great job. The graphics definitely helped.

This just sounds like the 4th dimension is a breakthrough trip (DMT). But I'm no scientist. Also stoked to see you doing these videos as I'd only stumbled on your comedy sketches! Your videos are awesome! =^.^=

it is the best video that i have ever watched since learning about dimensions!

4:32 I just realized how similar this is to Plato's allegory of the cave

This is the most helpful video about curled up dimensions I have seen in years. I appreciate how you differentiate them from extended dimensions, this has confused me for years prior to this. Thank you!

Thank you! I finally understand the basic premise of string theory

Wicked flavor saver, man!

The extra dimensions being on the small side rather than the typical science fiction depiction of "another dimension" actually makes sense when you consider that the size of an average human is a lot closer to the size of the entire observable universe than we are to the smallest known quarks. There's just that much going down there.

3:26 *Wait thats Sonic's personal ring collection!*

terrific video zach👍👍

I duly have been enlightened by this video. Thank you so much!

0:20 "But it's Einstein's theory of general relativity..." * Shows formula for Newton's law of universal gravitation *

Creating new spatial dimensions to solve questions in physics feels when you made a mistake in math class without realizing it, and you're wondering why you're getting all these long decimal values for answers when textbook answers are always nice and clean. It feels like a rabbit hole you can go deep into before you realize you just wasted 100 years of scientific discovery.

The idea that if things worked out differently during the big bang, we could've been 2D or 4D beings, is really neat to think about

I was thinking lately about "chance" as a dimension. For instance if you compare the movement in the chance of you being hit by a car to for instance walking towards a building. When you are very far from a building its very small to the point you dont see it, but then as you walk in space towards it, it gets bigger until you eventually touch it. If you then look at the chance of being hit by a car for instance when you are inside your house, the chance is so small that you dont actually "see" it happening. But then if you start moving outside your house and onto the street the "chance" gets bigger and bigger until you eventually "touch" the " chance" and you get hit by the car. So in effect you are moving in a chance dimension towards something happening. Then if you translate this to for instance "chance fields" all locations in space also have a certain set of chances in that chance field that change depending on how you move through them. When thinking about it like this we are also able to manipulate chances directly by certain actions we take just like movement through other dimensions like space. This is a train of thought I had when I was thinking how atoms and molecules interact the further you get out into space. In the vacuum of space the chance of these particles interacting also changes. Anyway, I think a lot about stuff like this as my job is in chemistry

This is the first to time in a valiant twenty year effort that I was able to actually fully understand 4th+dimension theory. I appreciate ya!

11:05 How beautiful math can be when explanations like this can almost create poetry. The world around us, on top and layered. So amazing. It was with us all along, the near divine nature of the world, laid bare with the language of math.

If you found this video interesting, I highly recommend Hyperspace by Michio Kaku. It was publish in the mid 90s I think, but it still discusses a lot of these topics in a similar manner. I was able to read and understand most of it while in middle school!

you’re really cool i love you and this channel

This is the most straightforward video I’ve seen on string theory, higher dimensions and parallel universes

A drunk man can see more than 11 dimensions while going to his house

You have a new subscriber. You explain it in layman's language and help me understand so much better

I wish loop quantum gravity was more popularized in media. Just so we can have something else to think about (besides string theory) when thinking about quantum gravity theories.

You hinted at something that always comes to my mind when I see a graphic of the universe expanding from a singularity to the stars and galaxies of today. With continued expansion, why couldn't the curled up dimensions some day expand to join the ones we currently experience?

I'm really liking this series,almost makes me regret not pursuing physics and maths..... almost

13:54 we need a video on each of these theories @zach star !

I have often wondered whether we could class all the different fields - magnetic, electric, gravitational etc and their respective spacial directions (up, down, forwards etc) as separate dimensions that interact with each other.

Interesting. Based on the animations, I had assumed inverting in the 4th dimension would turn you inside out, not mirror you. Layman here, enjoying your content :P

4:33 that flatland analogy explained the concepts of the extra dimension beautifully. that is the most clearest explanation ive seen.

Dang ive watched both of your channels without paying attention to the channel names so i had no idea that they were owned by the same person until i saw a comment in a Zack Star Himself video about aliens that said "its easy to forget this guy is a real engineer" so i looked at this channel and realized its had some familiar videos and that i watched both of your channels without realizing

You had me at "leaving me no choice but to find the weirdest stock footage that I can."

"And there's nothing that I or anyone else can do to change this beyond showing the weirdest stock footage that I could find" I don't know why but this made me laugh so hard 😂

I love how this is a perfect summarization of "Hyperspace" by Michio Kaku. Very well done

12:56sec, its symmetry breaking mayhaps... how different dynamics and forces represent themselves at differing scaling lengths, because a block has been taken out of the symmertric object or domain, like electron capture and the early universe.

idk if its just me but when you explained the part at 7:00 - 8:00 I lost it i completely felt like you explained the theory between either multi-verse/ Deja Vu because the way you explained it one day your one way and have done it and another your lifted into a higher dimension and flipped onto another day and if the multi verse theory was on the 5th 6th so on dimension that it is the cause of Deja vu?

This was really well done. Straight forward, brought together many terms and ideas that I couldn't relate well to each other previously. N1.

Hey Zach,great video i was one of your early subscribers (before you even revealed your face).You have amazing content and you explain key science and math concept without being too technical. Glad you reached this far. Good luck friend

OMG this is the best explanation of dimensions I have heard.

I love how higher dimensional beings are described in the three body problem series. Won’t give any spoilers. But damn is that an interesting concept. Obviously sci-fi and not necessarily tied to real science but it’s super crazy!

Can you try and do a video on Ramanujan's theta function? It's very interesting.

Well, I'm not a math lover but i'm so fascinated by it: it's not actually invented - it's just how things work in nature, but adapted to us by numbers, letter and rules, so we can use it to discover, invent and manipulate even the things we can't see. Mindblown.

Just found this. Very well done, imho. Thumbs up and subscribed. 👍

Just a small comment: Arround 7:16 Zach says that if we were lifted in a 4th dimention and turned arround we would have our body completly inverted, the heart on the right side, birth marks shifted to the oposit side, etc. I just want to add that also the molecules that build our cells would also be inverted. And since many of those molecules are quiral (they can exist in a left or right shape) we would probably not be able to survive, would not be able do digest most forms of sugar, and would haver many more issues with our biology am methabolism. Also the atoms and sub atomic particles in those molecules would have their spins reversed.

At 5:46 just hit really hard that what if the "ghost" or a figure appearing out of nowhere just might be a higher dimensional creature visiting us

I recently read Hyperspace by Michio Kaku. It's literally the same thing you've been explaining in your recent videos. Must read.

As a kid I loved anything that had to do with physics . It’s amazing even till this day.

For the first time in my life you made me possibly believe I understood a bit of the language that is Math. Thank you :)

me: lying in bed the hypersphere: *h o l a n i ñ o*

Omg, imagine if someone was diagnosed with 2D syndrome, where they can only see a 2D world. That be fuuuuucked.

Don't forget the "Theory" that the sun isn't actually a gassy hot mess, but a beautiful flower that opens into tunnels to other stars 👍🤔

I think we’ve figured out how the universe was made, some 11th dimensional being was just fucking around

Very good explanation skills my dude, u definitly deserve more views

thanks for curiosity stream promo love it

11:29 seems to be describing dimensions of time. Between 0-1 theoretically there are infinite decimal places and between each 0.1 increment there’re theoretically another infinite set of decimal places so you could imagine this as how zooming in on each 1 all the 0.1s are also curled up, this minuscule scale can probably only be accessed as as a digital realm

It reminds me of playing Dungeons and Dragons back in the 80s. We had a spell named "Rope Trick", where you could crawl up a rope into a safe extradimensional space in the middle of a dangerous dungeon and sleep/rest/heal. Then crawl back out and go around your business. lol

... gonna revisit this when the acid arrives...

I know you've started making different types of videos now such as these, but please could you do a video comparing a UK engineering degree and a US engineering degree?

4:18 Yup past me delivering Now you a relevant time-stamp. Trippy innit? TOLOKI.

Just amazing that you can derive maxwells equations by adding an extra dimension to relativity
