What model of the universe do you think is correct?
Big thanks to Ridge for sending me this wallet and supporting the channel! Here’s the site if you want to check them out! ridge.com/astrum/
Klein Bottle. Cause it's cool no other reason.
What about a combination of all three? We see space as flat; however, we've also observed that it has spherical properties, yet everything seems to be moving away from each other...
This only seems plausible within an unobserved hyperbolic universe.
Thanks for coming to my TedTalk. 😹❤
I'd like to side with you on this one, with your theory at the very end.
All three at once.
(Mostly just cause it sounds paradoxical, and paradoxes are fun.)
honest answer? any opinion i have is based purely on speculation. i don't have the mental tools to have an informed opinion. wildly interesting tho
“Flat”
For me space isn’t a ‘thing’ it just is. Matter is all there actually is. Einstein hasn’t done us a favour talking about ‘bending’ space time in my humble opinion.
It's amazing how the more we know, we see how much more we don't know
And we're not even sure of that
maybe multiple big bangs going off in a infinite space...
I know! I mean, I *don't* know. 🤔
this is so hiperbolic, dude
Hopefully we are learning.
Nothing is better than an Astrum video right before I go to bed. Love this channel.❤️
Haha I do exactly the same thing!
Very true statement 😂
As I hoover the carpet
Other excellent channels I’d like to recommend that explore the same themes and provides the same asmr type of feeling, are John Michael Godier, SEA and Cool Worlds.
I do the same thing every night lol
The visualisation of a hyperbolic space was godly - and I understand something now, I didn't before. Thanks.
yea i agree, it is amzingly pretty descriptive so well
You used something beyond your comprehension to describe something beyond your comprehension.Thats hyperbole, and it's not how it is done.
@@veronica_._._._ Hehe I see what you did there. It can't be far off though it's computer generated images with correct parameters entered and I recall an astrophysicist on PBS using a geodesic as an example of what outward curvature space would look like. So you can call it an educated guess even from a cynical point of view.
@@larrymunn5279 It's our brains that are finite, space cannot be.
@@larrymunn5279 It's like a handy 10 second IQ test .
Your contribution to the education of us all puts me in mind of Carl Sagan. You instinctively understand the need for visual representation and explain complex concepts in such a remarkably transparent way. Much richer than "The universe is like a balloon and we're all on the surface of it," which is how it was taught to me.
Yeah, I agree, I've never seen this second visualisation before
I'm glad I was able to give my thoughts to everyone. The hardest part was the effort it took to get to where anyone would take me seriously. I've always seen things differently yet clearly. I'm a designer and so communication of complicated ideas in an intuitive way 🙃 well, I love all you. And am gracious people were willing to listen. I've offered a lot. And the goal was to educate people, to demonstrate that we are smarter than we believe. In fact we can reinforce good things innour minds. people are coming together under a common understanding that we are all part of everyone and everyone is part of everything. We, therefore have a responsibility with what we do, what we say. Hopefully everything I've done helps the world fight the controversy. We can find a way to compromise for a better future.
@@thej3799 Did you produce this video? Or, did you help in its construction? Is that what you are referring to? I wasn't sure if I understood it correctly.
Hah! Never thought I would see the game that I worked on (Hyperbolica) as the artist here on this channel, what an honour! Cheers!
My parents and I love space, and we also discuss and throw around ideas. One was that our universe is inside a single black hole, and that black hole we call a universe is inside another universe, so on and so forth.
Been saying that for 10 years 👍🏽
Not inside. An event horizon of a 5th dimension black hole would have a 4 dimensional event horizon. Project this down to 3d and 4th is experienced linearly.
@@thej3799 But it IS inside an event horizon... Distances currently at 8 billion lightyears away are literally impossible for us to reach...
This universe is a black hole. Way too much symmetry with the spacetime diagram of a black hole compared to the big bang to simply ignore it...
Did you know that scientists have calculated the diameter of a black hole with the mass of the known universe in it, and the diameter nearly matched our visible universe? Not a coincidence!
I'm amazed with what humans have achieved by just observing the cosmos from our earthly perspective.
A great mathematics as well.
We know so much that we actually know that we know very little when it comes to howw much there actually is to know and discover
It’s also amazing how much we ignore, that could actually help our understanding progress far more
Achieved what exactly?
I;m amazed at what the universe has achieved by a very tiny small portion of it coming together to look back up at itself
Astrum is absolutely my favourite channel as of recently. Your content is amazing!
I think hyperbolic makes the most sense, especially when you consider the universe's fractal nature. Like you said, you open one door and two more appear.
Ok, and so, what is out of this?
@@factormars4339 nothing, as you go across the hyperbolic plane different types of energies and matter will be encountered some which we may not yet be aware of but for us at least and the way we can interpret the universe at this point in time space is infinite.
@@jamespostle6894 Nothing? You say this but you really don’t know. May be our universe is just a little part of the big picture.
@@factormars4339 maybe. Just my opinion. I think what's "outside" is currently beyond our comprehension. We don't even understand our observable universe yet.
@@jamespostle6894 exactly, and we will never fully understand the universe because WE are the universe, like a galaxie or a star, we are a little part of the matter of this beautiful thing.
I love your channel Astrum. Thanks for exploring these ideas.
This subject frightens me more than any iceberg video, more than any horror film or jump cut. The ideas discussed here just leave me reeling. Thinking about it I get the same feeling I got, when as a kid it dawned on me that everyone, including me would die at some point, it's a feeling of loss of control, that everything you know doesn't mean a damn, it's just an awful feeling that's so hard to describe.
Just do what I do and realize it's pretty much guess work. My guess is when telescopes get powerful enough, we'll spot another universe heading towards us and there is no end! Just like we see galaxies colliding with the help of our current telescopes.
Consider the musings of Alan Watts. Perhaps you (we) are not just what is in our bag of skin, but rather what the universe as a whole is simply doing at our point in space and time, that we are all an extension of this giant mass just as a blood cell is an extension of the whole human body. It switches your perspective.

Great video astrum, well done as always!
I like the idea of the spherical universe where you would always come back to wherever you started. It’s such a mind fuck.
That's just like the earth. What are you on about? 😂
Imagine if we're just some particle in another universe
A mote of dust floating around the unkempt room of a brooding teenaged alien. Imagine if they turn the light on and we're faced with an eyeball of universal proportions, as aware of us as we would be to a dust particle in our own scale :o

Great video, Alex! I’ve always liked the idea of a hyperbolic universe. 🎉
Such a well explained video. This makes the concept of time and the expanding universe much easier to grasp.
this video had a lot of things put in the wrong words, and if someone knows more than nothing about the subject it probable leaves them more confused than when they started.
Your videos is absolutely awesome, you explain very good and the scenery and animations are beautiful.
This topic is one of my top intrest.
I like the idea of the hyperbolic shape, is make the most sense to me. Cause of that everything is getting curved by gravity.
What scares me when thinking of this is how there are different infinitys inside of infinity. So at someone point everything would lead to its own infinity state within the ever changing infinity. The universe is weird and scary to try to comprehend.
It's not scary at all. Just because the idea doesn't fit inside your head doesn't mean it has sharp teeth and hungers for your flesh.
I do admit this thought is gnawing at my mind
@@deusexaethera lol
@@deusexaethera fear is relative. it does not have a set definition on what is and isn’t scary because everybody experiences it differently and to different things. the topic can make some people scared and some people joyous. everyone is different. nice try tho.
@@deusexaethera sounds like you're describing a cat. But Im not pointing out my basic fears, I'm pointing to my fear of an existential crisis trying to explain everything. Maybe one day you'll be intelligent enough to understand higher concepts.
The proverbial "educational video" that asks a lot of questions, but leaves you with that, "Ok, but I'm not really sure I actually learned anything" feeling
Yeah, videos are popular but not really that great to show science. There are video games in non-Euclidean geometries (HyperRogue is free with various 2D and 3D geometries), and books of course. Also there are other videos too (the CodeParade video they took some scenes from is good, or the ExtraCredits video about non-Euclidean geometry, but this is more about history).
True but also, these videos are redundant. There's no new info about the universe's size, etc.
No new discoveries about it. We're all just guessing. There's really no way to know.
Great great GREAT video!!! Wonderful theories, and “theoretical combination of theories “!!! The thought of hyperbolic space answering the dark energy/dark matter conundrum is fascinating!! Keep up the great work!!!
You material in your videos are amazing, I love how you make your own models and how you make things easy to understand, thank you 😊
Astrium, thank you for your content. I have been learning a lot and keeping myself informed about space with your channel. Love the thumbnail as well! Infinity plus infinity! 😂
You just totally made my brain explode!! I am studying the particles leaving my skull, trying to decide if the explosion is flat, spherical, or hyperbolic!!!
This really makes me think and I haven’t gone through the starting ads yet
I like a mix of all of them. Like a stretchy trash bag being filled planets and all kinds of matter. The lining of the trash bag itself is the gravity and those converging lines you talked about. Which is why when you have more stuff ( mass) at one spot you have a tighter bag (gravity) at that spot.
I like trash bag concept very scientific 🐒
Awesome that you used Hyperbolica for demo
your thumbnail is how i imagine it looks from the other side of each 'black' hole, (inside out universe kinda) with not necessarily white surroundings, but immensely bright surroundings and unimaginable energy, and maybe surrounded by other 'black' holes corresponding to each ones perspective of/in the universe. just thought i'd share, just a fun thought
Started watching Astrum because of cool facts of Pluto, then this... You really dragged me into a black hole of knowledge
This channel is getting more and more interesting!😍
#1 Space UA-cam channel. Very interesting subjects and so good explained.
Don't forget about the insane quality graphics
Since so-called parallel universes interest me the most, I go for finite. Our universe could still be one of these shapes that even change over time. The forces involved in parallel universes could easily influence not only the shape but significant characteristics especially if they touch ours at version points in time.
Parallel or multi universes its just story tale for those who like star wars and star trek 🐒
Look up supertasks. You can have a infinite space within a confined area.
@@whiteape2714 You say they are a "fairy tale", but there is evidence that back them up as absolute possibilities. You could even argue that an infinite universe, depending on how inflation occurs and the quantum fields separate, itself is able to be considered a multiverse.
There are many theories that have more assumptions than others, but there are many that are backed up while having fewest assumptions.
Thanks. You've given me some ideas for the climax of my sci-fi novel!
For me, this has been a remarkable film!!
I can't say enough great things about it!!
Thank you!!

Great video and fantastic narration. Thanks for this video.
As always, very nice work!!
One of the more easily understood presentations of the warping and shapes of spacetime.
The concept of "far more endless, far more infinite" intrigues and terrifies me.
Be wild if all the distant galaxies we see are the same few hundred or so with their light simply doing laps around the universe and showing us their state during a portion of each light-lap.
That hurts my brain😵💫
We have already disproven this idea a very long time ago.
There has NEVER once been a duplicate image of any star, planet, or galaxy in any of our observations, nor have we ever imaged things behind us when observing space ahead of us.
I've always thought about that, it'd be so fucking wild but I think space is just too big. Like no way to comprehend type big.
Questions:
a. Do spiral shaped galaxies eventually collapse in upon themselves?
b. Do all galaxies eventually collapse in upon themselves?
@@charlesbrightman4237 a)no
b) no
Galaxy mergers happen between multiple galaxies, but we've never seen a "collapsed" galaxy. If anything, galaxies shed mass by occasionally ejecting stars. Eventually, galaxies will in theory disperse due to the Big Rip. Were space contracting rather than expanding, perhaps they would collapse.

The rings around a black hole remind me of the way rainbows are visible but not there…
Actually it is possible to have a convex topology where lines can't be parallel but also don't intersect: A toroid, aka a donut. Lines attempting to be parallel along the surface of a toroidal topology will move closer together and then further away again, but will not intersect as long as they were truly parallel at their starting location.
Tho along some curves they could be parallel
@@SlyNine : Not if the lines are straight. (and straight lines are the only kind of true lines in mathematics.) Consider lines of latitude on a globe. They run parallel to each other, but they can only do so because they're continuously curving. You can't walk in a straight line and follow a line of latitude, except exactly at the equator. If you look at lines of longitude you can see what happens to truly straight lines running along a curved surface.
@@deusexaethera Baloney. Algebra produces curved lines all the time as does basic geometry.
You are wrong.
Excellent video, that´s an open mind to new windows to keep searching and developing a new kind of math to resolve it.
@Astrum Did you get a new microphone? So much clarity!
Cheers for the video mate 😎 👌
I get that the universe can't be endlessly expanding in all directions from all points of view, but that doesn't rule out the possibility that the universe does have a centre Somewhere, and everything expands ever outward from that one point, we just don't know where it is... am I wrong? Anyway thank you Alex once again for explaining everything so beautifully even my unscientific brain can understand it, your work is wonderful, I hope you never stop.
Basically where the Big Bang happened.
The big bang happened everywhere. Where you are, where I am, and at a place further than we have ever seen.
But it can be expanding from all points of view and that is what it appears to be doing. Think about putting some dots on the surface of a balloon and then inflating the balloon. Every dot will move away from every other dot. The center is not on the surface of the balloon. So applying that to our universe, space is the surface and the center would be in some extra dimensional space that we can't access.
@@davidkopp4291 The thing I defy anyone to get their heads around is that the universe was infinite, but prior to the Big bang, point like in it's infinity.
Infinite and infinitely dense feels like a more satisfactory sounding description, but that also has some major flaws.
The original mid point would expand because of inflaton. So everywhere would be that center. We could still be a singularity mid point, but all of its space expanded, so from "inside" it could look bigger and bigger. Like Dr Who's machine. An inner space bigger than the actual point this universe might be.
You have such great videos!!! I vote for hyperbolic or possibly curved.
We need a universal reset.....I need to go to Florida for that to happen
I'm getting extremely addicted to this kind of videos, and it's a fascinating subject to learn about it, definitely learning a lot everytime i watch this channel. Simply amazing!!!!! ❤️❤️❤️❤️❤️❤️😍😍😍😍😍😍
I bet that if you had some sort of impossible ship which could physically travel at infinite speed, that when you reached the edge of the expanding universe, you would just never be able to reach it, it would just always be in front of you, but just barely out of reach.
Whenever I was thinking of the universe and where it ends or what is it there, after this universe, I've always imagined it as a blank space. But then I was wondering where does this blank space end and if it's infinite how is it possible for space to be infinite? How does infinite look like? How can something go in forever? We humans know that whenever there's a beginning there must be an end. I will never comprehend it.
It reminds me when i was told infinity doesnt exist and everything has an end. I thought what about the universe? If theres nothing outside the universe, Then whats outside that nothing? And whats outside the outside?
I understand the blank space perspective. But unless there is "space" outside of a confined universe, you have to try and imagine the concept of nothing. It isn't impossible to conceive of, but it is a bit tricky. For me, I perceive it by trying to avoid noticing my mind's eye or perspective on the concept.
Infinite spaces can be in confined areas, this is called a supertask. There can be a multiverse where many of these exist in a extraversal space that may or may not have rules, dimensions, etc...
But my personal view? There are other universes, they are not able to be traversed across as they do not intersect. Assuming literally nothing exists out of them, you could argue that they are either separate or living parallel, effectively in the same place. Like if we were stuck on a 2d surface but attempt to move 3 dimensionally, translated to the universe including it's laws and all forms of influence.
Humans cant even comprehend a beginning or end. If there was a beginning to our universe what came before it and if theres an end whats after? If the universe didnt have a beginning how did we reach this point when its already existed for an eternity? Our brains just arent developed enough to comprehend paradoxes like these so we fill the gaps with sci fi like spacetime or religion.
Say; When the universe was born, The laws of physics and time most likely were made when the universe was made, The before and after most likely have foreign laws/no laws and we cant comprehend that because we are bound/accustomed to the laws present in our current universe.
Since there is no time in space, there was never a beginning or end. The human brain is a finite organism that cannot comprehend infinity. When you look at Max Planck and inject consciousness into science, it all starts to make sense.
Fascinating and very well explained. Thank you.
P.S. I like the look of that wallet too. I’ll check it out.

Wouldn't our universe itself have mass? What would be outside of it? Our universe could be a mass being entered into another hyperbolic timeline and causing the same effect as what you explained.
Draw a circle around what you know. Now draw a circle around that... So long as we are here we by the nature of ourselves in the context of the fundamental nature of the universe we will always be and can only understand "inside". Conceptually infinite. Bound between ideas of converging and diverging infinities.
@@thej3799 Or, one can imagine that the universe expands at a finite speed (even though this speed might be accelerating, it is still finite).
One can also imagine that it has only been doing this since the Big Bang, so a finite amount of time.
Finite speed * finite time = finite size. There is no infinite in nature, only finite.
Infinity is a mathematical concept, not one in reality.

thats kinda the big crunch theory, wich assumes a spherical universe
Universes don't go supernova. Thats just a term for a specific type of exploding star.
brilliant
thank you 🙏🏽
Hyperbolic is my vote. Perhaps something conical in shape or similar. I like to think this structure is finite and has a bottom edge all matter is racing toward. This edge slows and changes the course of all that cross it and send it hurtling back to a singularity.
My favorite explanation of hyperbolic spaces comes from a devlog by CodeParade for his game hyperbolica, would recommend checking it out if you are still having trouble understanding hyperbolic space.
I just watched a bit later into the video and saw that you used footage from that game lmao
Ive frequently thought we may have traveled (in the past) through a black hole, that they are recyclers of nature, and what we see is a view of (infinite times?) this. Ive also pondered if our idea of red-shift could be caused by gravitational lensing from our own galaxy expanding, making it only seem that things are heading away from us, which in fact the opposite may be true (or they are going nowhere, or collapsing even).
What your sharing, makes it seem so much more plausible that we may indeed have been sucked through some kind of black hole, and came out a singlarity, and this may also help shed light on what a singularity is. Maybe all we need to do is look up to see what a singularity looks like from its ejection point. Maybe a singllarity is just what we are all in, seeing things from the mirrored side of the end effect of being on the otherside, e.g. singularity being what we are experiencing now.
We can't travel anywhere using black holes
Mass off setting the hyperbolic curvature of space...
That is indeed an interesting way of looking at it. Maybe you're onto something there, afterall matter and gravity do seem at least to be properties inalienable to each other and seemingly only the way they are due to the simple presence of space to begin with.
Keep up the good work Astrum 👍
The more I think about it, imagining anything other than infinity gets harder and harder.
If the universe is expanding, how could it be infinite? If the universe is bigger today than it was yesterday, it is not infinite. They say at the moment of the Big Bang, the universe was infinitely small, so which day did it change from infinitely small to infinitely big? Remember galaxies aren’t flying away from us, the space between us is expanding. Is there anything outside of our universe we are expanding into? I doubt we will ever know.
@@alphagt62 the first one doesn't make sense. The universe is still infinite, just a bigger infinity. Just like how you can fit an infinite amount of decimal numbers in between 0 and 1, but there are also an infinite amount of whole numbers. The latter is a larger infinity than the former. But both are still infinities. Infinities are weird concepts like that...
The world is actually held up by 4 elephants
The elephants are standing on a very large turtle
The turtle is standing on another very large turtle.
From there it’s turtles all the way down.
This proving space time is actually curved as the turtles are actually standing on themselves.
I don’t know why it took me so long to come to this conclusion.
Great video. Thanks for clearing that up in my mind 🤠

i just have a question: if you can look back to within 300M years of the big bang in one direction, if you look 180 degrees in the other direction how far back should you be able to see?
The same
the same, big bang happened everywhere. It is not like it happened in some space and we can look at it from far away. It happened everywhere, so no matter where you look, you will see the same.
@@ozymandiasultor9480 aahh, so we're the center of the universe then eh?
@@syx3s Everywhere is the centre of the universe because the Big Bang didn't happen here or there, it happened everywhere. It's difficult to wrap our heads around but it appears to be the case.
@@syx3s YES! If the Universe did start from a single point, then any point you choose now - wherever it is in the Universe now - was that point in the beginning. So when people ask me where is the center of the Universe I can say, "I am the center of the Universe!" and not be wrong....
I like the hyperbolic theory. It explains away dark energy, which feels like lazy astronomy to me. It's like when archaeologists can't explain something so they wave their hands around and say "It must be ritualistic".
But you would still need to explain with the theory why it only actually started to be hyperbolic 5 billion years ago? Surely if the cosmos were naturally hyperbolic that expansion would have been there from the beginning?
@@CountScarlioni Maybe it's always been hyperbolic, but the hyperbolic shape only became apparent once the universe grew large enough? On some scales, it's impossible to see the shape of something until you're far enough away. I'm not an astrophysicist - I'm probably wrong about all of this. It just feels logical.
Wow we are blessed with both a SEA and Astrum video in one day.
Absolutely great episode, easy to understand. I hit the 'like' 3 times!
If the universe is infinite, then how could there be a Big Bang? To me, it seems the theory of the Big Bang is impossible.
From a perspective in which the universe is infinite, you can't imagine the singularity as a point only, you'd need rather to imagine the evolution of the Big Bang from the singularity until the present moment as a change of density of the universe, and therefore of entropy.
When you first saw an object. Like say you observe a new car. Now, the car essentially was non existing in your world. Now it is. Pretend you're part of the car. What would it be like for that part to suddenly "be" Now in the world- your mental construct- the universe as you know it..? 🌻
A closed universe isn't infinite. But it is still effectively infinite if it expands faster than the speed of light, which is what we deduce from the red shift of galaxies. i.e. the universe can have a finite volume at any given moment and yet not even light could ever get back to its starting point.
i agree with your final point that the 3 theories are likely working in tandem. the fact that we can postulate the theory of hyperbolic space based on the evidence in front of us shows it’s a possibility that we just can’t prove yet. and we’ve learnt over time that our perception isn’t perfect, it’s at the mercy of the reality we find ourselves in. like the visualization from one of your older videos about a man in a solid walled box flying through the vacuum of space not being able to really tell with certainty that they’re moving at all. we may just be inside the box with no way to break through the wall yet, being limited to what we can see from our limited point of view. it’s all a bit overwhelming to think about when you’re just a hobbyist like me hah hopefully i don’t just sound like an idiot pretending to be smart hahahah
Being self aware enough to know you could sound arrogant instantly shows you're not arrogant or tryign to sound smarter than you are :)
If we are inside a box kind of thing, I wonder if a super large hadron collider could break or rip through it? That would be cool.
Two important points: 1. There is a difference between the shape of spacetime and the shape of space. 2. Our best measurements show that space is either flat or extremely close to it.
Unfortunately this video neglected to mention these very important facts.
Thanks again for your attention to detail.
Very nice topic and presentation.
Is it possible to build technology fast enough to counteract the infinite expansion of the universe in order to discover the entire universe? Seems like self correcting code
If we wanted to "counteract" the expansion we'd have to invent a way to travel many times faster then light. And star trek like warp wouldn't cut it. I'm talking millions of times the speed of light here. As even without the expansion it would otherwise take way too long for even multiple generations to explore the entire universe. In fact, by the time we might have invented such a method we'd likely have to be able to travel at over a billion times the speed of light to explore the entire universe within any kind of decent time frame.
I'd say it would already be a good enough accomplishment if we managed to explore our entire galaxy though. Because even for just our galaxy star trek warp wouldn't be enough. At over 1000 times the speed of light it would still take you more than the current average human lifetime to just get from one end to the other in a straight line, let alone explore the entire disk and all it's hundreds of billions of stars. (Yes, billions. Not millions)
Such an interesting question, because all the possibilities seem ridiculous. An edge? Crazy. Infinite? Crazy. Curved? Crazy. A simulation? Crazy.

There is another even more exotic possibility! The curvature of space need not be uniformly curved in all localities. Certain localities can be convergent, while others are divergent.
Thank you, that was well explained.🙌🏻
Nice Video
One of my favorite channels to fall asleep to. Then I have to rewatch the video the next day....🥰
I always thought space was like standing inside 2 hyperbolic mirrors attached to each other so I'm happy to see that visualization makes sense.
That was awesome ! Thank you :)
Epic video!!!
Love this channel ❤
Mind boggling. Love these thought experiments. 😎
I''l go in the direction of the sphere, but go a step further and call it torus like. The the center or spindle is so constricted that you can't see it so it offers the appearance of a sphere. The other idea is similar except the center of the sphere or torus is synonymous with its out side surface (3D) in 4D this would mean if you reached the 3D outer surface (event horizon) then you would emerge from the center.
Fun video to watch after just finishing War of the Worlds season 3, which covers some of these topics.
