I might be mistaken but isn't that hypercube animation supposed to be a depiction of a 3D slice of a hypercube moving through the fourth directional axis? Or is it just supposed to be a direct depiction of one like how we would draw a cube on a piece of paper?
@@phillemon7664 This animation only show you what you would notice in our Universe but you would need REAL (almight) 3D vision because we actually see in 2D (parallaxes 👀 🧠) in 3D(for now) Universe ==> You wouldn't see real hypercube as it is in 4D just little slice of piece moving. Fourth dimension in some way is not "adding" but rather "multiplying" (much more combinations) REALITY. ==> Would be funny if "random lines" and others "failed artefacts" in 4th dimension would be able (with little of luck) project REAL universe in 3D from our perspective 🤔👀ツ ==> Just saying ¯\_(ツ)_/¯
astrum made a great video on this subject. But you can see it visually , hyperbolic space, if you meditate on it while not giving into thoughts. it's always the way reality is but its easier to see with meditating
This is true. And ur on the right path. It will terrify you. People who do dmt are have nde said they seen the truth in the univer all the way down to the atoms and more and this scared some but then soon there was a great peace.
The fundamental level of reality is spirit. And when the body dies the spirit enter into a quantum state. And be able to perceive life as it really is.
Words cannot express how great the diagrams and comprehension were in this video, my jaw was dropped a few times during my ‘aha moments’ . Thanks Alex!
This whole video is simply incredible. Never has a video taken so many concepts that were so abstract and difficult to grasp and visualize make so much sense. I was fascinated and engrossed in this video for ever second it was playing.
I recommend a book called " A GUIDE FOR THE PERPLEXED" it talks about the different levels of life and being and dimensions, each higher level can understand the lower levels, but the lower levels cannot fully understand the higher levels. for example, try explaining to a dog why you're sitting in front of your pc and pushing buttons. God claims he had no beginning and has no end. In the dimension we live in, TIME and SPACE is a thing. I personally don't believe we can ever fully understand. whether or not you believe in God is a totally different matter.
Yooo holy shd I was thinking in my head about seeing higher beings in each dimension that has no idea what’s beyond and as I travel further to the edge I enter other dimensions and another keeper understands how you got there but doesn’t understand what’s beyond either crazy
I don’t mean to be “hyperbolic,” but this just might be the most fascinating TH-cam video I’ve ever seen. I don’t think I’ve ever seen a random TH-camr share an original scientific theory that is both plausible and potentially revolutionary. I’m not smart enough to know if your theory is true, but I’m blown away at your courage to present something like this so honestly
It's alllllll copied straight from a childrens/teen book of the 1800s called Flatland. Its famous. Mention it to a well read old timer & their eyes light up. IT WAS TABOO at the time BIGLY. It's fiction. It's all theories. There IS no 1D nor 2D def no 4D. PROVE IT. Besides what we chose to name "ours" which is the 3rd. Flawed logic. So you have been fooled. Not only by this bogus long laughed at theory, but by thinking this man had an original thought just bc he has a soothing indo brit accent. Sorry he's a thief who doesn't even give credit at all to what he copied (drawings and all!) verbatim to make YT money. Tacky. He's a spell caster. THAT is why he's allowed on YT.
NOTHING IS REAL,WE ARE LIKE ANIMALS JUST SMARTER,FOR NOW.😮😮😂.WE ALL DIE NO HELL NO HEAVEN.THATS WHY, WE FIND OTHER PLACES ON EARTH WHERE PEOPLE USED TO LIVE, WE JUST START OVER N OVER N OVER. RICH , POOR ALL DIE BUT IF U KNOW SOMEONE THAT'S KNOWS BETTER HIS KOOOKOOOOOOW😮😊
Characters in your dreams figuring out they are simulation? We have evidence the dreamer itself can discover its role and can manipulate its imaginary simulation. So, every character in your dream is a manifestation of you in an internal discussion revealing answers to some subconsciously abstract generated scenario with meanings unique to only you. They are all you
Sometimes I have weird experiences because of epilepsy, there are moments where I start to feel kinda scared, I loose control of my thoughts but I totally feel and think "I understand everything now", it feels like nothing has importance anymore, it happened many times but I always forget what I was understanding, it is driving me crazy but maybe is just a brain disfunction.
Sounds similar to what happens when we dream, and then cant recall most or all of the dream images. All we can do is enjoy it when it happens...then let go of the desire to hold on to it. Easier said than done. I wish you well.
Our sentience is part of the universe. When consciousness is altered it can be scary, because we’re not in control of it, but that feeling of “understanding everything” means something. You’re not alone in having that experience. It’s reassuring to know that Understanding is attainable.
Maybe it's Just the FACT that your government has been lying to you and the rest of us our whole lives, I think your just trying to figure out why so many things your told Just don't add up ( ' , )
This is probably the best illustration of spacetime I've seen. A wonderful feeling when you finally see and think "Of course, that's it!" Thank you Astrum.
He actually stole this entire video from the book "Flatland". I read it in 8th grade. He's no genius. He's a content thief while thanking ppl for giving him credit! Just bc the author lived over 100 years ago doesn't make it not 100% thought theft. I can not believe he didn't give the author any credit. WOW. Brazen.
@@jungfopo3024 I read a bit about that book and it just seems to be entertaining the idea of 2D beings, it may be a predecessor to the thought experiment conducted in the video but how is it content thievery?
What does the speed we are already going at on Earth do to our perception of time ? Aren't we as part of the expanding universe now traveling at near the speed of light , or even relatively faster , away from another galaxy ?
@@doncahootithat depends upon your reference frame. Basically the galaxies moving away from each beyond light speed is irrelevant. Now, we *are* moving, but not very fast. So this is also pretty much irrelevant. Also, there's no absolute velocity, only relative velocity. So it's hard to say how much faster time might move. I suppose you could add the rotational velocity on Earth's surface, Earth's orbital speed, Sol's orbital speed around the galaxy and the Milky Way's orbital speed around the great attractor, determine how much dilation you get from that velocity and subtract it from how time moves on Earth to get a "stand still" time speed. Gravitational dilation is interesting too. When they sent the GPS satellites into the 0.03g gravity of geostationary orbit they found their receiver was super wrong. So they reset the Cesium clocks and it worked great... For a few seconds when the tiny difference between the satellites (moving at orbital speed BTW) and the clocks on Earth. They had to figure out exactly what that difference was, then send a software update to adjust the onboard digital clock to the faster running cesium clocks in the satellites compared to the cesium clocks on Earth.
28:26 With respect: When you derive that light travels at infinite speed from its perspective, you say time becomes zero but forget to change the distance. Length contraction should also be considered. Since you take the photon as the reference, everything else moves with the speed of light and shortens to zero. So we get a 0/0, which is undefined not infinity. You could do limes calculation, and I guess you would still get C.
Your graphical models and animations are hugely helpful for me to try and hold visualizations of these phenomena and relationships. A great video. The hyperbolic model seems to have a great deal going for it - at least at my level of understanding.
Alex, once again, you've given me the tools to grasp what I had previously only glimpsed, and in doing so given me both a greater understanding of the universe, and a greater perspective into the mind of someone more intelligent than myself. Thankyou.
I always find this fascinating, like looking at distant galaxies, we don't see them where or how they are but where and how they were. Probably the closest we'll get to time travel.
Another weird thing to realize is that the galaxies might look skewed not because of the angle we are looking at them, but because of how fast they are moving relative to us.....
The farther away something is, the more the light we see shifts to the red, thus is called"red shift" and I see one taken recently from the JWST of what looked like a little red smudge way in the background! It turns out to be the farthest object we've ever seen! Its light has been traveling for fourteen billion years only five hundred million after the beginning of our universe! That is amazing! Thanks for taking the time to respond!
I don't understand a lot to be honest. But damn - I love this. Not often in my life I heard someone talking about science in such an easy and natural, yet intelligent and challenging way. I will watch it until I get it. Thank you so much for this great content.
Don't worry, if the people making comments here were completely honest, they would admit they don't understand much more than you! I have studied Einstein's theories for half a century, and I still don't really understand them either!😢
Seems as though gravity is faster than light. I wonder what the speed of gravity from a black hole is. It's kind of like water displacement in a way I think. Yin and yang possibly?
@@stanzanossi the people here making comments either seem to all be working on the same brain or a lot of BOTS because a lot of these comments are just saying the same thing over & over
The assertion in the video depend on, Time is a 4th dimension and the speed of light is constant for all observers. What if, as some claim the Michaelson Morley experiment was not the whole answer. Then the subject of the video has no valid basis. Would love to see more on the basis details.
The hyperbolic model actually makes a lot of sense! How can there be such large forces in the universe that bend light reaching our eyes and not think the reality we see is actually a byproduct of a hyperbolic spherical equilibrium! God, I love Astrum for explaining this concept❤
Most of of the ugly fractions and sqrts of the equations in special (and sometimes general) relativity can be replaced with single hyperbolic equivalents of trig functions (like cosh instead of cos, sinh instead of sin, etc)
I believe that time is the biggest enemy of consciousness. And that trying to hard to figure it out. Simply is the best way to separate us from the NOW. Because everything that ever happens in what matters happens NOW. And that's what's important. Connection to True Consciousness.
You pointed out something I've never considered before. Assuming there was a "Big Bang", why limit the number of dimensions which expanded from this event. Time expanding, is simply one of these dimensions, and explains why time appears to move in only one direction.
Subatomic informaton shared faster than the speed of light due to entanglement so the big bang is like your brain exploding from metaphysical to physical explains fractals as it may only be you here with a neural subatomic entanglement
@@kimberlysmith5404 Two time dimensions could explain the absence of antimatter. Matter in our universe would have gone "forward" in time and antimatter would have gone in the direction of the other time dimension. Therefore the two types of matter would never have met and annihilated each other.
@@richardrose2606I find this fascinating tbh We can't even comprehend what time is, the idea of an entire separate "other time" running in parallel that we will never be able to perceive
You and your brother do amazing work! Great topics, scripts, fantastic narration! I especially love your different perspectives on these topics. You introduce interesting topics in ways that are easier to digest compared to other science channels, yet provide a great deal of fascinating info! ❤❤🎉🎉
Man celebrated 4/20 a little too hard, and took notes. This is an amazing demonstration. Simple enough that anyone can understand, but deep enough to learn advanced topics for those who may already know stuff about this topic
No no no HE READ THE BOOK FLATLAND AND TOOK NOTES. No, he copied the entire BOOK. Which is fiction BTW ICYMI like 99.9% of the comments here. (No one reads world famous books anymore & the guy knows it $$$$)
@@JasonSpielberg was always famous & well known. No one reads anymore. Thats why. Prolly your generation if you're a zoomer or act like one due to conditioning by not understanding that.
This is not a theory. See scientific method. This is not a model. There is no thesis, there is no math. This is a video about other scientist put in an incoherent blender.
Your explanation at the beginning about 4D is the best I've encountered so far! While I sort of get the mathematical concept, it is still hard to visualize, and most 3D comparisons end up confusing me more. This one really has me thinking about it visually in a much clearer way.
Well you shouldn't 'visualize' it in this way, because it's incorrect, simply because every nD representation in an (n-1)D world can only ever be a simulation. Conceptual, fine, but _visualizing_. does not help because it's definitely not like that.
my mother said , when I was about three years old the first thing I said when I looked up at the sky was “how far does that go”? I still wonder, and when you think in terms like that, anything is possible..
I usually don't ever watch something twice. This I had to come back to review. Not because it was hard to understand, but because it was beautiful. Good job.
It's "brilliant" that he totally ripped off the world famous book Flatland? Oook uneducated masses..... This man has ZERO shame at all. This is why it's good to read. You can't be fooled by hacks changing already wrong theories & you instead see what people are made of! NOT BASIC LOGIC. Fooled by a indobrit accent like so many are SMH. That soothing voice will get ya if you aren't careful lady. Read the book instead & do your brain a solid. It's not brilliant, you are just unlearned. Also it's not even true lol It's old news that it's all made up. Where is this 1D & 2D? Oh yes, in "our 3D". Perfect. If you can't see how flawed that is, stick to YT vids maybe after all.
I feel like this model just clicked right and it all make sense now. This model is very well explained and beautifully simple! I hope this will take us one step closer to the true shape of our beautiful world!
26:00 It’s either infite or it’s not, but It can be both… The real question is who’s behind all of this? Is there a creator outside of this infinite space? Honestly this video did not help with my depression whatsoever. This might sound cliche but I believe that the only true reason why we exist is to evolve as species, and experience the complexity and beauty of life in different forms, colors and shapes. Astrum and his brother are truly amazing. This video is a 10/10 the visuals and your way of explaining things in a simple and understandable way made everything click together. Awesome work!
I believe there is God.. but u have to understand.. God is not the same like his Creations.. if u wanna read more.. u can read panentheism.. hope u find something...
11:54 This little model finally helped me understand why time goes slower for objects moving fast. I kind of understood it on an intellectual level, but seeing it presented this way really made it click. Holy hell that was a light bulb moment!
The common explanation provided, which is very similar to this, is "just imagine" time as another dimension you are able to "travel through", and the setup is that you have a movement vector of length c, that can only and always be length c; you can go in any single direction, or any combination thereof, but it's always going to be of length c. So, you can be at rest in space and move at c through time, or you can be at rest in time and move at c in space, and any middle combinations. The math of time dilation follows this description exactly, which is why Astrum can simply state that this is how our universe works.
I absolutely loved this. It made me feel simultaneously more a part of everything and completely alone. I can see how mass shapes our universe, but I don't know if it's right
The universe must be infinite, because if it weren’t, it would have to be “contained” inside of something - and what would that “container” be floating in? It makes no sense that the universe would have “boundaries,” because that implies something else existing outside of them.
And THAT is the question that causes the most intelligent people to falter. I don't know that the human mind is capeable of comprehending what the answer would be. I know mine isn't.
It’s such a simple question I can’t believe people are not able to question they think there is some known universe with some boundaries and they accept it easily universe is infinite indeed
I wanted to let someone know. That I had a NDE a few years ago and for about a month after I came back I could look at the door are the walls and see that it wasn't real. I don't know how this happened but it did and I can't forget about it.
"But the professor has no time He’s got a paper to write And the next thing on his list Is to prove that the universe does not exist" "Ivory Tower" by Sabine Hossenfelder.
Beginning to end your greatest video! Meticulously structured to understand the payoff in the end. After all I’ve studied and read this brought so much together. I honestly think you’ve nailed it, or are at least close here. A simple truth that explains the reality we observe. Fantastic, thank you!
I think you’re spot on. Which is why time stops at the event horizon of a black hole and and at the cosmic event horizon. At those points in spacetime all lines away from you diverge and merge with the time it takes for light to travel. Describing Hyperbolic space. A straight line from the center of a black hole to the edge of our cosmic horizon would be hyperbolic when measured against time from the observers perspective.
Any massive object would curve spacetime around it resulting in what we see with some gravitationally lensed galaxies having supernova appear at different times depending on the refracted image.
I'm incredibly curious about these concepts and I've seen many different explanations, however, this is the most intuitive and interesting explanation I've seen yet. Well done!
Easy to do when you rip all your content from a world famous author from over 100 years ago from a book called Flatland. No credit oddly enough. Funny, you'd almost think he thought he came up with that whole way of explaining these bogus ideas himself! You'd be mistaken & were taken for a ride from a grifter. Do better.
i love how he said "now before you check that you haven't logged onto some sci fi channel by mistake, let me explain. and i say this not because it amuses me - no that's too simple - it made me have the immediate thought that hes taken the time to ponder That there might be, NO there WILL BE, people watching this, and possibly for some - this video in particular FOR THE FIRST TIME and knows how cynical or jaded some people are. with all the click bait stuff on here now, he directly shows and states there is education and fact to his videos. YOU ARE TRULY MEANT TO spread knowledge and i see and know you love to learn and to share what you've learned with absolutely any and everyone who's interested and that'll listen...NEVER CHANGE THAT FOR ANY REASON AND KEEP THE WONDERFUL VIDEOS COMING. I feel like i'm always getting a fresh perspective and new facts every time !!
That's not you feeling time, that's just your perception of it depending on how busy your mind is, you don't notice time if your mind is busy, if not busy then you are aware of the time, that's all, you are not feeling time.
@snoutysnouterson8387 yes where that is a certain fact, i do not think that it proves that we cannot "feel time". For example, when we are in winter months, we are farther away from the sun, therefore it makes time slow down a bit, and vice versa during the summer months where we are closer to the sun just marginally in difference, but enough to definitely say that the winter months feel longer than the summer months. Just some food for thought buddy.
@@Rick-or2kq but if entropy exists (which is a scientific fact), then automatically time exists, because Time is the progression of entropy (or events) in Space
I imagine 4d as looking at all sides at once. That includes the interior. If 4d was time, rather than looking at one side physically, you can move through time and let the space move by itself.
Flattening 3d space into a 2d model so that we can visualize time as a 4th dimension finally made the 4th dimension make sense to me. I love how just explaining something another way can make something suddenly interesting.
In that case, you might enjoy more videos on non-Euclidian geometry. I could offer you some recommendations (though there might be some that are better than the ones I'm thinking of that I simply don't know about)
Very beautitful and interesting lecture Alex! One of your best... i also think in existence when I am alone sitting in our house and the last who is going to sleep, existencial questions, time to think, to feel and to imagen our universe that is so vast and incredible rich in expressions!
Starting with VSauce's "Which Way Is Down?" and layering the concepts that this video covers on top of that knowledge actually results in a (semi)intuitive understanding of the supreme weirdness that is Einstein's theories of relativity. This is elegantly done and mind-expanding, thanks for putting it together.
He stole all this from the book Flatland. He just stole it without giving the actual author any credit at all. Elegantly stolen you meant lol NORMAL PEOPLE GIVE CREDIT. PERIOD.
This was really enlightening for me. Time is what allows movement. My head just grew a lot dude. It is so simple. I feel incredibly foolish for not ever putting it in those terms even when contemplating space time.
Read a book. That is where he ripped all the content for this video from. It's called Flatland & it's quite famous among intelligent folk. He didn't even give the brilliant author one note of credit. Shameful.
Another thought that tripped me out when I heard it, was in reference to dreams. Every person you've ever interacted with in a dream, was created by you. Every object in a dream, was created by you. How can it be that within the confines of our brains, when we dream, we can create entire worlds with realistic physics and people with entire personalities. Makes me wonder about mind and Mandelbrots. Like, could my mind be contained in another mind? If I could click into a dream and never click out, it would seem like I wouldn't know the difference between dream world and real life. But the dream world is all allegedly taking place in a portion of my brain. That is super weird to me. It makes the notion of me being just a product of "mind", a lot more acceptable.
I love your videos man. I've only watched 2 so far but intend on watching more. I'm aware of most of the concepts discussed but you have a way of explaining them which also gives me understanding. Thanks!
Yes it's called ripping off the entire book Flatland. SOOOOoooooo genius. Gee, why didn't I think of ripping off some amazing author's content! Oh yes, I'm not a THEIF without morals!!! And you guys wanna hero worship this guy w the silly accent lol NORMIES
I still can't get my head around the scientific fact that we all get a perfect and constant speed of light, and it is us who speed up or slow down to preserve this frame of reference. Keep up the good work, the visualisation of physics neeeds constant effort from those that can.
DOe not the frequency or shift of light have an effect on how fast it does or does not go? I think the secret to everything is in frequency to be honest. A bandwidth is being sent here from a higher dimension or something and being denizens of this reality we cannot go outside of this bandwidth because in this reality outside that bandwidth doesn't exist.
You still think a telescope from the 40s, when we could barely get a decent black & white movie made regularly, COULD TAKE PHOTOS FROM 13BILLION YEARS AWAY????? Or how about a decent zoom on a cell phone? Too hard. But the beginning of the universe (which is now 2x as old as they lied & told us forever ICYMI recently....) NO PROBLEM!!! We can see into the past maaaan..... soooo far, that it's far ouuuut. We can see the big bang man. Uh huh. Riiiiiight. Logic me that please. Take your time......
I think you did a superb job explaining a lot of these ideas. Honestly the best I've seen thus far because even things that I had seen explained before really only now clicked with me, although that can always be subjective and relative. Thank you and I really wish more physics-classes would use explanations like this to ground a lot of the theoretical.
The Hyperbolic Universe hypothesis as i'll call it sounds really appealing to me as well, I've watched this video a couple times now, really wrapping my head around it. Going back to the model with the 2D stickman, I've been playing around with concepts and I extrapolate "time" for us by looking at what a 2D object would experience as time and what you would see. If you take say a square, adding "time" to this square would be pulling the entire 2D object through a 3rd dimension so in a 2D world, time creates a 3D object, but also, what are you seeing for the 2D square throughout that 3D shape? You'd be seeing the change of that 2D object, whether it's moving in space or not, it moves in time. I think about time similarly for us in 3D, our time axis is the 4th dimension and we are being pulled through this 4th dimension, creating a 4D object that shows our changes in space. While writing this out i'm also having the thought that what we exprience as "time" is actually a "force" somewhat similar to gravity, or actually counter to gravity which would be the explanation for why gravitational effects distort time. The time pull would be constant so you wouldn't see an effect on gravitational things, but gravitational-like effects can vary and hence the pull from time can vary. Still need to do some more reading and thinking but i love stretching my brain around the topic of spacetime, maybe the model is a little too simple and inaccurate but i'm here for the criticism.
Exactly right because it's all made up. No 1D, no 2D no 4D=Time lol We just named it 3rd but could have named it something else instead to avoid future people being tricked by Godless nonsense spreaders
Some years ago, I wondered if maybe the reason the universe was expanding at an accelerating rate might be that it's "falling" outward, but this is the first time anyone's ever explained to me how it could do so in a way that I could understand.
Why do you care? You think you CAN KNOW? Really? Ok, God. Let us know GOD. So smart us humans are to think we can fathom anything like this when we can't fathom our own oceans. Ignorance at its finest. This guy steals his best content from famous books that actually were ground breaking. Dude gives no credit. That is low moral behavior. Do not trust a person like that. All he had to say was, "read Flatland, it's where all my visuals came from, to learn more"
What if instead of a sphere space time is shaped more like a magnetic field? You said something along the lines of sphere like space would curve around something. But since we hypothesize everything started from a single point, everything could just be moving away until suddenly it's going back together again in an eternal space-time-loop of stretching and compressing. That would be cool. Space would be both finite and infinite because eventually you'd be back at the start. Idk how possible that is but....food for thought haha
I think a good way to see why time is like a dimension is flipbooks, those books with a different drawing on each page that make a video when you flip through them. Each image is 2D space, when you flip through the 3rd dimension the 2D world comes to life and moves.
The reason why we cannot see in the direction of Time, is because that process your looking for has not happened yet. Until Time reveals the process, only then can we see towards Time. Light speed is one direction, without change, until something moves in the path of light. So, this is why Time would slow down when approaching light speed, is because we would be approaching an area where time does not exist, cause light obeys no process. Think about what process takes place when you flip on a light switch? No processes exist, light just instantly appears.
I've always enjoyed the content on this channel but when I saw the video was 41 minutes, I was worried I'd lose interest or that I'd struggle to pay attention and finish it. Thankfully, that wasn't the case and I was thoroughly intrigued for the entire length of the video; It was well mapped out and explained and actually showcased your knowledge of multiple subjects and how they all fit together!
I love this explanation of hyperbolic space. I have never had a solid intuition of it before. Thank you! It seems that this really does rule out FTL and wormholes, right?
I dont think we would back in time, because seems like with the birth of time dimension the 3d space started. They go find to hand because of cause-and-effect relationships. Means we should back before so called big bang , before the time was born
Your video is absolutely amazing, as much as I thought I knew you were still able to open my mind to possibilities I never knew existed. Thank you very much.
By stealing the book Flatland but acting like he came up with the "amazing way to explain it? NO, Edwin Abbott did. He just ripped it off pretending it's his own. Being a TOTAL content thief without any giving credit is really shameful behavior for those who put in a TON of work for others to snatch. Be wary of people like this.... No reason to not include it AT LEAST in the description unless u are selling yourself as some genius. Everything he's saying is ripped off!
Wow! This is fantastic!! Couple of questions: 1. Why only 4 dimensions? Is it because we cannot fit a higher number dimension in our thoughts? 2. Why is the value of c 299792458 m/s? Why not something else?
Amazing and mindblowing visualization and explanation. One question: If light does not perceive time while it travels, and we imagine it has some kind of consciousness, wouldn’t the universe happen at the same time while for the light not even a second has passed? And additionally, if future and past just exist in our mind because we have a memory, wouldn’t the universe just exist in one single moment? And combining these two thoughts, if there is just one moment and for light there is no time, would the whole existence just be one moment without time. Like a dot.
Wow! I had a friend, Uncle George, we theorized that there was only one particle that makes up the entire universe. Since we are all made up of this one particle, we experience time as a way to complete the process of the particle making us up.
Past and future might happen in same one moment, we see time move because we are aware of all moments and combine them to become a string of events, one by one, making us feel there is an order, there is time. Its all about awareness.
@@danmurray1143 good question! Distance is always an illusion, we manifest every single thing that we see or hear..., even this video or this whole universe(s) including distance and time. The source for this manifestion is iur awareness/ wisdom. If there was no bigbang, we might simply exist in another form of energy or no form but always with awareness/wisdom which decides which form to look like or which events to experience in whatever way. In singularity, all dimensions might be pressed to become something we in 3d never know or just nothing. Only through meditation, we liberate into our higher self ( of higher vibrational energy with infinite wisdom or awareness mentioned above) and see again our trueself, who we are by nature and what happening and why. This video is physically describing what our higher self (more than 3d) would look like right in this chosen version.
Im only now at 40 only just getting to grips with this subject but your video is by far one of the best out for view Absolutely please keep up the great work and i hope you keep your wonderful mind active ❤❤ Many thanks
This video was so incredibly amazing! I had an amazing moment where I remember learning about length-contraction and how to calculate it but never understood that it happens due to you moving through another dimension. The way that these very complex questions about our universe were so *simply* explained was really good. Thanks for making my this.
WHAT, This was not an explanation. Rather a perception and estimation. Meaning; guessing with your limited imagination. At the end of the day, this video only proves that Man is not alone. There mathematically has to be a greater force with access to much more dimensions; including the ability to see and travel through time, whether past, present, or future. If any natural Humankind was in a super fast spaceship, time will still only move in a forward direction at the same speed. There has to be a Being greater than Humaninty to monitor and manage this other dimension called time. Hence how Humanity can get Dreams of Future and Fortune Tellers can connect through various Sources to see and discover Past, Present and Fortune of someone or something. Powers of Prophecies.
I love how you admit that a 3D version of a 4D hyper cube does not improve your understanding of another dimension. Thank you for being human!

astrum made a great video on this subject. But you can see it visually , hyperbolic space, if you meditate on it while not giving into thoughts. it's always the way reality is but its easier to see with meditating
This is true. And ur on the right path. It will terrify you. People who do dmt are have nde said they seen the truth in the univer all the way down to the atoms and more and this scared some but then soon there was a great peace.

I recommend a book called " A GUIDE FOR THE PERPLEXED" it talks about the different levels of life and being and dimensions, each higher level can understand the lower levels, but the lower levels cannot fully understand the higher levels. for example, try explaining to a dog why you're sitting in front of your pc and pushing buttons. God claims he had no beginning and has no end. In the dimension we live in, TIME and SPACE is a thing. I personally don't believe we can ever fully understand. whether or not you believe in God is a totally different matter.
Yooo holy shd I was thinking in my head about seeing higher beings in each dimension that has no idea what’s beyond and as I travel further to the edge I enter other dimensions and another keeper understands how you got there but doesn’t understand what’s beyond either crazy

Sometimes I have weird experiences because of epilepsy, there are moments where I start to feel kinda scared, I loose control of my thoughts but I totally feel and think "I understand everything now", it feels like nothing has importance anymore, it happened many times but I always forget what I was understanding, it is driving me crazy but maybe is just a brain disfunction.
Sounds similar to what happens when we dream, and then cant recall most or all of the dream images. All we can do is enjoy it when it happens...then let go of the desire to hold on to it. Easier said than done. I wish you well.
Our sentience is part of the universe. When consciousness is altered it can be scary, because we’re not in control of it, but that feeling of “understanding everything” means something. You’re not alone in having that experience. It’s reassuring to know that Understanding is attainable.

The vectorial representation of c-limited travel in spacetime is brilliant, and made me really understand the concept for the first time. Thanks!
That's because "c" is the speed of causality. And mass is the difference.
What does the speed we are already going at on Earth do to our perception of time ?
Aren't we as part of the expanding universe now traveling at near the speed of light , or even relatively faster , away from another galaxy ?
@@doncahootithat depends upon your reference frame. Basically the galaxies moving away from each beyond light speed is irrelevant. Now, we *are* moving, but not very fast. So this is also pretty much irrelevant. Also, there's no absolute velocity, only relative velocity. So it's hard to say how much faster time might move.
I suppose you could add the rotational velocity on Earth's surface, Earth's orbital speed, Sol's orbital speed around the galaxy and the Milky Way's orbital speed around the great attractor, determine how much dilation you get from that velocity and subtract it from how time moves on Earth to get a "stand still" time speed.
Gravitational dilation is interesting too.
When they sent the GPS satellites into the 0.03g gravity of geostationary orbit they found their receiver was super wrong. So they reset the Cesium clocks and it worked great... For a few seconds when the tiny difference between the satellites (moving at orbital speed BTW) and the clocks on Earth. They had to figure out exactly what that difference was, then send a software update to adjust the onboard digital clock to the faster running cesium clocks in the satellites compared to the cesium clocks on Earth.
@@UpperDarbyDetailing - irrelevant huh ?
you sound like you almost have a grip on what you're talking about - but no cigar .
28:26 With respect: When you derive that light travels at infinite speed from its perspective, you say time becomes zero but forget to change the distance. Length contraction should also be considered. Since you take the photon as the reference, everything else moves with the speed of light and shortens to zero. So we get a 0/0, which is undefined not infinity. You could do limes calculation, and I guess you would still get C.
The answers 42, everyone knows this.
You reached 28 mins without falling asleep?😂
Your graphical models and animations are hugely helpful for me to try and hold visualizations of these phenomena and relationships. A great video. The hyperbolic model seems to have a great deal going for it - at least at my level of understanding.
Time is an observable change of state.
Alex, once again, you've given me the tools to grasp what I had previously only glimpsed, and in doing so given me both a greater understanding of the universe, and a greater perspective into the mind of someone more intelligent than myself. Thankyou.

I always find this fascinating, like looking at distant galaxies, we don't see them where or how they are but where and how they were. Probably the closest we'll get to time travel.
@@oldschoolman1444 whooooosh
anytime we see Mars there is a delay of between about 3 to over 20 minutes depending on its position in its orbit compared to us.
It's like file permissions on a computer file. Future files are write-only. Past files are read-only. Present files are execute-only.
Another weird thing to realize is that the galaxies might look skewed not because of the angle we are looking at them, but because of how fast they are moving relative to us.....
The farther away something is, the more the light we see shifts to the red, thus is called"red shift" and I see one taken recently from the JWST of what looked like a little red smudge way in the background! It turns out to be the farthest object we've ever seen! Its light has been traveling for fourteen billion years only five hundred million after the beginning of our universe! That is amazing!

I don't blame you this video is from the fourth dimension is not easy to understand
Seems as though gravity is faster than light. I wonder what the speed of gravity from a black hole is. It's kind of like water displacement in a way I think. Yin and yang possibly?
@@stanzanossi the people here making comments either seem to all be working on the same brain or a lot of BOTS because a lot of these comments are just saying the same thing over & over
The assertion in the video depend on,
Time is a 4th dimension and the speed of light is constant for all observers.
What if, as some claim the Michaelson Morley experiment was not the whole answer. Then the subject of the video has no valid basis. Would love to see more on the basis details.
The hyperbolic model actually makes a lot of sense! How can there be such large forces in the universe that bend light reaching our eyes and not think the reality we see is actually a byproduct of a hyperbolic spherical equilibrium! God, I love Astrum for explaining this concept❤
Exactly
It also just makes sense to me that the universe would be very geometric.
You seem smart and I'm pretty darn dumb so...can space pass through space? Like how the old representation of a 3D orb that passes through a 2D paper?
Or it makes sense for us to try to understand in a geometric way.
Most of of the ugly fractions and sqrts of the equations in special (and sometimes general) relativity can be replaced with single hyperbolic equivalents of trig functions (like cosh instead of cos, sinh instead of sin, etc)
I believe that time is the biggest enemy of consciousness. And that trying to hard to figure it out. Simply is the best way to separate us from the NOW. Because everything that ever happens in what matters happens NOW. And that's what's important. Connection to True Consciousness.
Tilting the 2D man to show length contraction was so simple but increased my intuition greatly.
I guess that's why i watch your videos. Nicely done.
You pointed out something I've never considered before. Assuming there was a "Big Bang", why limit the number of dimensions which expanded from this event. Time expanding, is simply one of these dimensions, and explains why time appears to move in only one direction.
Subatomic informaton shared faster than the speed of light due to entanglement so the big bang is like your brain exploding from metaphysical to physical explains fractals as it may only be you here with a neural subatomic entanglement
Why couldn't there be two (2) dimensions of time? I've always wondered about that.
@richardrose2606 who says there isn't 2 dimensions of time, perhaps going either direction, forward, and backward. .....
@@kimberlysmith5404
Two time dimensions could explain the absence of antimatter. Matter in our universe would have gone "forward" in time and antimatter would have gone in the direction of the other time dimension. Therefore the two types of matter would never have met and annihilated each other.

Well you shouldn't 'visualize' it in this way, because it's incorrect, simply because every nD representation in an (n-1)D world can only ever be a simulation. Conceptual, fine, but _visualizing_. does not help because it's definitely not like that.

The common explanation provided, which is very similar to this, is "just imagine" time as another dimension you are able to "travel through", and the setup is that you have a movement vector of length c, that can only and always be length c; you can go in any single direction, or any combination thereof, but it's always going to be of length c. So, you can be at rest in space and move at c through time, or you can be at rest in time and move at c in space, and any middle combinations. The math of time dilation follows this description exactly, which is why Astrum can simply state that this is how our universe works.

The universe must be infinite, because if it weren’t, it would have to be “contained” inside of something - and what would that “container” be floating in? It makes no sense that the universe would have “boundaries,” because that implies something else existing outside of them.
And THAT is the question that causes the most intelligent people to falter. I don't know that the human mind is capeable of comprehending what the answer would be. I know mine isn't.
The end of our space boundary is the beginning of another universe.

What simple truth is that? Asking for everyone because it's unclear from the video.
this helps me greatly understand better. i can see you've put the hard work in
Kudos to such editor which explain us such wonderful and complicated phenomena with great ease.
I think you’re spot on. Which is why time stops at the event horizon of a black hole and and at the cosmic event horizon. At those points in spacetime all lines away from you diverge and merge with the time it takes for light to travel. Describing Hyperbolic space. A straight line from the center of a black hole to the edge of our cosmic horizon would be hyperbolic when measured against time from the observers perspective.
Any massive object would curve spacetime around it resulting in what we see with some gravitationally lensed galaxies having supernova appear at different times depending on the refracted image.
I'm incredibly curious about these concepts and I've seen many different explanations, however, this is the most intuitive and interesting explanation I've seen yet. Well done!
Easy to do when you rip all your content from a world famous author from over 100 years ago from a book called Flatland. No credit oddly enough.

That's not you feeling time, that's just your perception of it depending on how busy your mind is, you don't notice time if your mind is busy, if not busy then you are aware of the time, that's all, you are not feeling time.
@snoutysnouterson8387 yes where that is a certain fact, i do not think that it proves that we cannot "feel time". For example, when we are in winter months, we are farther away from the sun, therefore it makes time slow down a bit, and vice versa during the summer months where we are closer to the sun just marginally in difference, but enough to definitely say that the winter months feel longer than the summer months. Just some food for thought buddy.

How can it be that within the confines of our brains, when we dream, we can create entire worlds with realistic physics and people with entire personalities. Makes me wonder about mind and Mandelbrots. Like, could my mind be contained in another mind? If I could click into a dream and never click out, it would seem like I wouldn't know the difference between dream world and real life. But the dream world is all allegedly taking place in a portion of my brain. That is super weird to me. It makes the notion of me being just a product of "mind", a lot more acceptable.

@jungfopo3024 You have problems man. I bet you're a reddit regular. You also like your own posts. Cringe.
Thank you, I shall now spend the evening unblowing my mind... Brilliantly presented...
very intersting content you make, with very good animations, that fit. definitely a like for this.
I still can't get my head around the scientific fact that we all get a perfect and constant speed of light, and it is us who speed up or slow down to preserve this frame of reference. Keep up the good work, the visualisation of physics neeeds constant effort from those that can.
👏👏👏👊💥💯
DOe not the frequency or shift of light have an effect on how fast it does or does not go? I think the secret to everything is in frequency to be honest. A bandwidth is being sent here from a higher dimension or something and being denizens of this reality we cannot go outside of this bandwidth because in this reality outside that bandwidth doesn't exist.
there are no scientific facts, only theories
....could this (as well as gravity) be why the Jmes Webb Telescope is finding galaxies that seem to be 'older than they should be'?
👍 good question 👍
You still think a telescope from the 40s, when we could barely get a decent black & white movie made regularly, COULD TAKE PHOTOS FROM 13BILLION YEARS AWAY????? Or how about a decent zoom on a cell phone? Too hard. But the beginning of the universe (which is now 2x as old as they lied & told us forever ICYMI recently....) NO PROBLEM!!! We can see into the past maaaan..... soooo far, that it's far ouuuut. We can see the big bang man. Uh huh. Riiiiiight. Logic me that please. Take your time......
I think you did a superb job explaining a lot of these ideas. Honestly the best I've seen thus far because even things that I had seen explained before really only now clicked with me, although that can always be subjective and relative. Thank you and I really wish more physics-classes would use explanations like this to ground a lot of the theoretical.
Excellent video, it really breaks down these concepts and shows them very well.
Then tell us what specifically you learned.
I can see the effort you put into this video and kudos on the production :)
You deliver interesting information in a very soothing way. Your videos actually help me with my anxiety. Thank you so much.
Brilliant video - well done and thanks for posting!
The Hyperbolic Universe hypothesis as i'll call it sounds really appealing to me as well, I've watched this video a couple times now, really wrapping my head around it. Going back to the model with the 2D stickman, I've been playing around with concepts and I extrapolate "time" for us by looking at what a 2D object would experience as time and what you would see. If you take say a square, adding "time" to this square would be pulling the entire 2D object through a 3rd dimension so in a 2D world, time creates a 3D object, but also, what are you seeing for the 2D square throughout that 3D shape? You'd be seeing the change of that 2D object, whether it's moving in space or not, it moves in time. I think about time similarly for us in 3D, our time axis is the 4th dimension and we are being pulled through this 4th dimension, creating a 4D object that shows our changes in space. While writing this out i'm also having the thought that what we exprience as "time" is actually a "force" somewhat similar to gravity, or actually counter to gravity which would be the explanation for why gravitational effects distort time. The time pull would be constant so you wouldn't see an effect on gravitational things, but gravitational-like effects can vary and hence the pull from time can vary. Still need to do some more reading and thinking but i love stretching my brain around the topic of spacetime, maybe the model is a little too simple and inaccurate but i'm here for the criticism.
Sean I am not a genius but if you ever want to talk about a problem you are working on I am interested. I like how your mind works.
Brilliant presentation as always, thank you
Thank you so much for putting this together. It really got my imagination working. ❤
Exactly right because it's all made up. No 1D, no 2D no 4D=Time lol We just named it 3rd but could have named it something else instead to avoid future people being tricked by Godless nonsense spreaders
I am so thankful that you make these videos 🙏
This was a great video! Kept me intrigued, but more importantly, you’ve explained everything very well! Thank you!
Some years ago, I wondered if maybe the reason the universe was expanding at an accelerating rate might be that it's "falling" outward, but this is the first time anyone's ever explained to me how it could do so in a way that I could understand.
Quite a novel idea. I've never heard that before. Intriguing.
Why do you care? You think you CAN KNOW? Really? Ok, God. Let us know GOD. So smart us humans are to think we can fathom anything like this when we can't fathom our own oceans. Ignorance at its finest. This guy steals his best content from famous books that actually were ground breaking. Dude gives no credit. That is low moral behavior. Do not trust a person like that. All he had to say was, "read Flatland, it's where all my visuals came from, to learn more"
This is ABSOLUTELY the best video explaining these phenomena. wow.
Always going to be a great fee kinutes when Astrum posts a new video
What if instead of a sphere space time is shaped more like a magnetic field? You said something along the lines of sphere like space would curve around something. But since we hypothesize everything started from a single point, everything could just be moving away until suddenly it's going back together again in an eternal space-time-loop of stretching and compressing. That would be cool. Space would be both finite and infinite because eventually you'd be back at the start. Idk how possible that is but....food for thought haha
I think a good way to see why time is like a dimension is flipbooks, those books with a different drawing on each page that make a video when you flip through them. Each image is 2D space, when you flip through the 3rd dimension the 2D world comes to life and moves.
The reason why we cannot see in the direction of Time, is because that process your looking for has not happened yet. Until Time reveals the process, only then can we see towards Time. Light speed is one direction, without change, until something moves in the path of light. So, this is why Time would slow down when approaching light speed, is because we would be approaching an area where time does not exist, cause light obeys no process. Think about what process takes place when you flip on a light switch? No processes exist, light just instantly appears.
I've always enjoyed the content on this channel but when I saw the video was 41 minutes, I was worried I'd lose interest or that I'd struggle to pay attention and finish it. Thankfully, that wasn't the case and I was thoroughly intrigued for the entire length of the video; It was well mapped out and explained and actually showcased your knowledge of multiple subjects and how they all fit together!
The possibilities are exiting, just shows how small we are in comparison to what’s around us in space
I love this explanation of hyperbolic space. I have never had a solid intuition of it before. Thank you! It seems that this really does rule out FTL and wormholes, right?
What makes you think hyperbolic space in a non-scientist youtube vid proves Stephen Hawking wrong? Does anyone here know what science is?
I mean, alcubierre drive style stuff is still an option, but ftl from an immobile perspective, no.
@@smarts_artsIsaac Newton didn't even know what science was.
The visualization and application of hyperbolic geometry was probably the most fascinating tangent that I had to dig into further after watching this.
I think this is brilliant, and it was explained in such an understandable way.
I saw somewhere yesterday that said if we went faster than light then we'd go backwards in time.
Love your video. The best explanation out today.
I dont think we would back in time, because seems like with the birth of time dimension the 3d space started. They go find to hand because of cause-and-effect relationships. Means we should back before so called big bang , before the time was born
They go hand to hand**
It's the same
We can't travel faster than the speed of light In this gravity.
We can travel through the past with EASE, but it's not a physical time travel, you have to do it mentally.
Your video is absolutely amazing, as much as I thought I knew you were still able to open my mind to possibilities I never knew existed.
Thank you very much.
By stealing the book Flatland but acting like he came up with the "amazing way to explain it? NO, Edwin Abbott did. He just ripped it off pretending it's his own. Being a TOTAL content thief without any giving credit is really shameful behavior for those who put in a TON of work for others to snatch. Be wary of people like this.... No reason to not include it AT LEAST in the description unless u are selling yourself as some genius. Everything he's saying is ripped off!
The truth is we are small, less than dust. We live and we die here and we cant leave.
This tells me that if we ever figure out how to teleport, we wouldn’t age but others who didn’t use the portal would. Wow. Crazy thoughts
Daleks dont age so ther u go 😊
Reality doesn't exist as a physical space, it's a giant energetic web of information and it's all constructed in our mind through the five senses.
Right on man 😊
Graph or no graph, I'm just here to confirm my suspicion that my lost socks are indeed in a parallel universe.
Yea I thought about too when I ordered the new ID & debit card yesterday; I may have left them in the other dimęntion.
Wow! This is fantastic!! Couple of questions:
1. Why only 4 dimensions? Is it because we cannot fit a higher number dimension in our thoughts?
2. Why is the value of c 299792458 m/s? Why not something else?
Brilliantly explained even for the layman which is so rare, You and your brother are pure geniuses and I look forward to more of your videos.
Amazing and mindblowing visualization and explanation.
One question: If light does not perceive time while it travels, and we imagine it has some kind of consciousness, wouldn’t the universe happen at the same time while for the light not even a second has passed?
And additionally, if future and past just exist in our mind because we have a memory, wouldn’t the universe just exist in one single moment?
And combining these two thoughts, if there is just one moment and for light there is no time, would the whole existence just be one moment without time. Like a dot.
Light is just ripples in the aether
Wow!
I had a friend, Uncle George, we theorized that there was only one particle that makes up the entire universe. Since we are all made up of this one particle, we experience time as a way to complete the process of the particle making us up.
Past and future might happen in same one moment, we see time move because we are aware of all moments and combine them to become a string of events, one by one, making us feel there is an order, there is time. Its all about awareness.
@everythingfromzero What if we're still in the singularity (i.e. big bang never really happened) and distance is just an illusion?
@@danmurray1143 good question! Distance is always an illusion, we manifest every single thing that we see or hear..., even this video or this whole universe(s) including distance and time. The source for this manifestion is iur awareness/ wisdom. If there was no bigbang, we might simply exist in another form of energy or no form but always with awareness/wisdom which decides which form to look like or which events to experience in whatever way. In singularity, all dimensions might be pressed to become something we in 3d never know or just nothing. Only through meditation, we liberate into our higher self ( of higher vibrational energy with infinite wisdom or awareness mentioned above) and see again our trueself, who we are by nature and what happening and why. This video is physically describing what our higher self (more than 3d) would look like right in this chosen version.
Outstanding, elegant, and understandable explanation.
Im only now at 40 only just getting to grips with this subject but your video is by far one of the best out for view
Absolutely please keep up the great work and i hope you keep your wonderful mind active ❤❤
Many thanks
This video was so incredibly amazing! I had an amazing moment where I remember learning about length-contraction and how to calculate it but never understood that it happens due to you moving through another dimension. The way that these very complex questions about our universe were so *simply* explained was really good. Thanks for making my this.
WHAT, This was not an explanation. Rather a perception and estimation. Meaning; guessing with your limited imagination. At the end of the day, this video only proves that Man is not alone. There mathematically has to be a greater force with access to much more dimensions; including the ability to see and travel through time, whether past, present, or future. If any natural Humankind was in a super fast spaceship, time will still only move in a forward direction at the same speed. There has to be a Being greater than Humaninty to monitor and manage this other dimension called time. Hence how Humanity can get Dreams of Future and Fortune Tellers can connect through various Sources to see and discover Past, Present and Fortune of someone or something. Powers of Prophecies.
