[@mullergyula4174]

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.

[@seanmcdonald5365]

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.

[@doncahooti]

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 ?

[@UpperDarbyDetailing]

​@@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.

[@sedameansstrong]

Helps me to somehow understand the contents of the Qu'ran and I also recommend all of you to dwell into scientific studies of near death experiences! Most people who clinically were dead for a minute, talk about entering a higher dimension where they suddenly have a vision of 360* and all. They say it cannot be described, although one guy said that the visual sensation is similiar to seeing fractals. They also report to have seen heaven (or hell) - Spiritually speaking (so this part doesn't need to be believed:) I experienced extremely short snipped of places/ things, where I was looking at an object or interior that appeared so ultra sharp... when I remember those snippets later, their intensity lessens, until I have a new "snippet" / image in my head, that refreshes that feeling of what that sharp image looks like. So in short: I believe after we die, it's likely our Soul wakes up to the 4th dimension. And I also assume that wormholes are angels traveling. As they are beings made of light. If we are made out of earth and we move with solid legs, it makes sense that angels who would be made out of light, travel in light speed. Probably nobody will read this but I felt like sharing.

[@kindlin]

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.

Here’s another idea… The principle of fractiles, as I understand it, means that a small part of a large object resembles the large object. From this standpoint, an infinitely small “object” (which I postulate = consciousness itself) resembles that which is infinitely large (the universe). On another episode of your show, I commented that something infinitely small could travel faster than the speed of light. I think that is also consistent with a very simple, basic idea being true.

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!

[@jungfopo3024]

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.

We can absolutely feel time! Sometimes it feels slower. Sometimes, it feels like we speed through the day.

[@viktorianas]

The last minute of microwave timer while you watch and wait... The slowest time movement known to mankind that basically warps the space-time.

[@snoutysnouterson]

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.

[@cameronwillinger3041]

​@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.

[@REktSigMa]

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.

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.

Time is something you live in ones, it passes you by in all directions, and you can’t never go back to its original point to change it.

[@Robienko]

I just have a guy feeling the true nature of reality is as vast to what we see as the light spectrum compared to just the visible light spectrum for animals who can only distinguish light from no light. I don't think it would be scary. I just think we miss so many things that could be advantageous in every second of our lives. Even the greatest puzzle solvers in my opinion, haven't started to truly think outside the "box" if it is even a box at that level.

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.

[@louierankin1485]

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.

[@acidrock9935]

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.

[@2sdayrobbins]

The whole speed of light and time thing is always a word game to me because it applies to everything and nothing because you’re looking at yourself in the mirror you’re looking at yourself from milliseconds ago but when you’re in a completely dark room does time stop because there isn’t any light? Therefore, in space which is darkness with “stars” in this darkness, which light bounces off each other which is also why you see fragments of light when bouncing of another light object, mean that time is maybe not soemthing that we can truly comprehend because with all that bouncing we can’t truly know if your seeing in the past or the future because light travels, it doesn’t travel just back. So, we truly don’t know if we’re seeing on the past or future. It’s like a movie, we don’t see the light of the upcoming pixels but it’s there and we know it’s there, so the same I’d think applies to any light you’re seeing. Idk 🤷🏼‍♀️ I’m going off and I may not write exactly what I’m trying to mean so maybe someone can help me, and hopefully try to understand at least what I mean.

[@brynparrott7361]

Here is something to consider: If the universe was created from a point source discontinuity, why is it not a topological shell. (like a ballon) ? What we observe is instead a volume filled with energy and “matter”. Meaning some parts have expanded more from the source than other parts. Why?

[@y5mgisi]

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 believe there is no dark energy, the galaxy rotation anomalies we see that indicate hidden mass is actually caused by gravitation of the inner galaxy making the center of the galaxy look like it is moving too slow when actually it’s a function of time dilation.

2:00 What is time? 3:13 ... one foundamental idea: time is actually another dimension. ... 7:10 ... that fourth direction, or dimension, is time. ... According to him time and space are two parts of the same thing. 7:27 .... 16:24 ... and to do that, we need to begin by talking about infinity. 24:28 what's different to say it due to Dark Energy and Hyperbolic universe, do you know what Dark Energy is, why not its form is hyperbolic spacetime. Time and space is the same thing in different realms caused by speed limits, we simply express the idea as 2d(2τ)1δ(1t) || (τ1)d1(2t)2δ 3δ(3t) || (τ3)d3,

[@greggrant670]

In the model showing stick figures moving through time, the stick figure really should not *move* through time, like he moves through space, because he would exist in all times. That's what's confusing about this. You don't exist in all values of x or all values of y but you do exist in all values of t. So if he were the shape of a disk in the x-y plane, and not moving through space, then he should be the shape of a cylinder in x-y-z space, where z is time. That's why when you travel through space and then stop, you see the x-y slice of the cylinder from your position in time. Because it's always there. It doesn't have to be "projected into your space plane" as described. It's already there. So these diagrams would be less confusing to me if you smear them through time rather than move them through time, as if their existence at earlier times is somehow deleted as they move vertically.

Time isn’t a dimension, it’s that the speed of information has a limitation. The more of the processes per-second you diverge an information particle the less time in its cycle it has to interact in its local space.

[@user-ji6ze9pb2w]

Movement = Time = Gravity (In space) We move fast as the lightspeed trough the universe with the sun that makes time for us. If you "jump off" that you will possible notice that time changes on earth, but not as fast with you. The trouble is to get back to earth. Cause it have travel the lightspeed away from you... I would say that 4th D. is the movement we travel trough the Universe we can't see. It possible we move in a wave that goes in a big circle. Almost like pasta shape with so much galaxies that we can't see it for real.

[@Mr.Isquierdo]

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.

Loving it is like to add another perspective. We all know we travel in time at C and when you accelerate you're taking speed and actual space from time dimension. Realistically there is no simultaneity in the universe does someone at the other end of the universe doing something at the same time you are lightspeed not enough to prove simultaneity

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!

[@SatisfyingWhirlpools]

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.

[@theonebman7581]

Idk if someone else has thought of this before (I mean, probably yes, there's a lot of people and there's been a lot of time), but I find it fascinating how one dimension can be inside another If you take a sheet of paper, that sheet of paper is by all means a three dimensional object; anything you do to it will be 3D, drawing a line with a pen causes a three-dimensional dent into the paper But think of the sheet itself. You can draw anything you want in it, you can draw a square, you can draw a circle, you can draw a triangle... but have you ever drawn a cube? Like, actually. For real. Have you ever been able to draw a three-dimensional object on a sheet of paper? At least to me, this would imply there's a form of "universe" inside the 3D sheet that is completely 2D and you could never have anything that isn't 2D inside that universe; drawing a line would just be drawing a really thin rectangle, drawing a cube would just be an hexagon, and drawing a point would just be a dot, which itself is just a really small circle. On a similar sense, everything inside our universe is 3D, and there could be nothing that isn't 3D inside of it; you can't have a 2D object, because purely and solely by it existing here, it'd have volume

[@DipankarBanerjee-vs8si]

[@lilymanders5178]

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

[@newyorktours8496]

Time depends on the change in the position of a particle in space with respect to another or other particles used as reference points to measure movement and time. Time is movement in space, and space is the movement of particles with time; because they are both the same thing measured differently in our current interpretation of the universe.

[@doublestarsystem]

The 3d Universe is perhaps only the cast shadow of a 4d Universe, which might be not material at all, like a 2d disc or circle is the cast shadow of a sphere
