what's funny with knowledge is that the more you acquire , the more you realise you lack a HUGE chunk of it; hence it could be our eternal quest

Whenever I feel depressed, I watch videos related to universe and that makes me realise that I am too small compared to universe and my problems are even smaller compared to me. So, there is no problem to worry about.

“So that’s our answer: the universe expands unto itself,” she says, as though that makes any sense

The more you know the less you know

The universe needs to give us some...space.

To me, it's unbelievable how far we as a species have come. Being able to observe the universe and how it behaves, making scientifically inspired assumptions about the very fabric that EVERYTHING is made of... just unbelievable! I'm so glad I'm still young, so there might be one or the other mind-blowing discovery in my lifetime... I'm really hyped for this!

I always knew legos were the foundation of the universe. It explains why I always step on one on the way to the bathroom in the middle of the night.

We are all just living on a giant loaf of raisin bread, preparing to be eaten by a great cosmic fatty. So beautiful.

I can't even imagine what the "outside" of space is like. I mean, space is an empty void, right? So how can a void be absent of emptiness?? And I can't imagine how space is expanding because how can "nothing" expand? What is "nothing" to begin with? Is there a state of nothingness that is more severe than "nothing"? God, I should be sleeping right now.

Once in grade 6 I asked my Science teacher this question, he deadass said the universe is expanding within the milky way galaxy

"these aren't just wild guesses" then they proceed to tell you the most widely talked about wild guesses

The big bang is still bangin' *to this day!*

I've wondered this since I was a kid in Starlab. They said the universe was expanding and my first thought was "Where to? Into what?"

I’ve been itching for this question to be answered

"The Universe is expanding unto itself"

I am so addicted to existential questioning videos on TED-ED, i need rehab

I’ve always wanted to know this

My brain broke 🤯

Thanks you so much TED Ed, your videos never disappoint me!

I love this channel. Its the best channel on RU-vid. I can just binge watch ted ed videos.❤️

I always come here to learn something new. Hats off to TED-Ed as always

I like how she sounds so confident talking about theories and hypothesis...

The more I see such videos on universe, the more complex everything becomes to comprehend!

I’m genuinely trying to understand what‘s happening in the second half of the video but my brain just starts overheating every time😂😂

Can you guys collaborate with in a nutshell please. That would be amazing.

no one gonna talk about how ferb from phineas and ferb asked this question?

THIS!! This is literally what I've been coming up with in my brain for the story I'm making and the fact that this is an actual theory that exists is just fascinating

I‘ve always thought of it as the universe just expands into a higher dimension. Just think about how a 2D-Plane takes up no „space“ (volume) in a 3D-Room. So you could put an infinite amount of 2D-Planes into an infinitely small 3D-Room. This is true for higher (spatial) dimensions as well. Thus our 3D-Universe could expand into a 4D-Room/Space which itself is inside a 5D-Room in a 6D-Room and so on and so on... Thus our universe is „located“ in an infinitely high dimension which is infinitely small. But nobody knows the real answer so just my two cents on this question.

All my life I've always wondered what I wanted to be, I've been stuck right now in college for almost 5 years switching and shifting courses yearly, can't really finish one because I don't have any motivation to push through... But everytime I see a study about universe, deep in my heart I know that I wanted to be a Scientist and an inventor.. But i don't think that would ever happen... just how I wish, maybe someday..

Yes, the universe is forever expanding into itself. This is an eternal cycle of constant unveiling. Thanks for sharing.

Loved the song used in this video. So hypnotizing.

Q:"Where is the universe expanding to?" A:"It's expanding into itself." 😒

It's obvious that the Universe is expanding into Uranus. Leave my Nobel Prize at the door.

Imagine an endless soup of energy stretching in 3 dimensions (4 if you include time). Now that endlessness stretches... every point at once. When stretched, it cooled down, and allowed for matter to form... again, in all points simultaneously. The time it took for light of that stretch to reach us from other points relative to us is the reason why what is close to us appears cold and dark, whereas the further away we look into the distance (and therefore time), the more of the universe's history we see, beginning from the actual expansion. Those distant points today are at the same stage of expansion as our point in the universe... cold and dark... but appear as red hot due to the time it took for light to reach us. Some of the most famous discoveries involve tight clusters of galaxies, that could only exist right after they were formed, before they had the time to distance themselves. These can be observed at the very boundaries of our visible universe, which are also expanding at the speed of light...(due to the time it takes for those areas to reach us). Hence why the saying: "the further away you look, the further back in time you see". The very boundary of our universe shows only light... similar to looking at the inside of a bright plasma... things were too densely packed for matter to exist, and only elemental particles were there. It is impossible to answer what was there before the universe, as that would involve seeing beyond the actual expansion... something which is impossible to do. But I like to think of the universe as existing in a form suspended state, similar to Schrodinger's cat theory. One moment it's there, one moment it's not. Particles hopping in and out of existence in our observations seem to prove such a theory. What may be now a state of existence will eventually meet its demise through a big chill or big rip (depending on Plank's constant, something still being measured today)... which will in turn make the universe cease to exist... until a state of quantum states let it exist again. The whole "in between" transition is what we are living today. It's a very short blip of time on the cosmic scale, but appears like an eternity for us humans.

This video left me more confused in the end than the starting

Everytime I hear about the creation of the universe, it gives me goosebumps

Ted-Ed is an amazing channel. I always smile when I see Ted-Ed has uploaded because it means I get to learn something new! I hope they never stop uploading.

What a wonderfully simply way to describe the speed of farther way galaxies.

our universe is very amazing, the more we increase knowledge about it, the more we realize that we don't know anything about it, and that proves that there is a creator for the universe is more greatful than we could imagine so we are required to seek to increase knowledge about him

The narration, the animation and the concept of your videos is just _Amazing_ !!!

Amazing video as always!

An interesting place to start towards answering this question, for me, would be to reformulate the question. When space expands, is it implied that any previously non-dimensional point on the plane expands into 3 spatial dimensions(at least those we can perceive) as well?

I knew we didn’t have a fun answer but I still got excited for some knew information

I love the music in this video... It sets a mystery-evoking mood.

I love that ur videos aren’t super long, and they’re really awesome😀😍

Who knows~? I don’tknow what’s what, it’s so fun to see scientist argue about universe. How they do things like that? I respect their a way of thinking. It always leads ue to taking it to the next level. That super!!

This is a GREAT explanation for those who are novices with respect to astrophysics. I will definitely use this to teach others.

"The universe is under no obligation to make sense to you." No. But it is obliged to make sense to itself. And relegating the answer to the title question to "higher dimensions" and "the multiverse" doesn't really solve any of the underlying, fundamental contradictions. It just sweeps them further under the rug (or, I suppose, out the door).

Great video like Always

Seems like just another story for the matrix we are living in

I've wondered to myself about this question but didn't know how to say it in english.I learned this from you."what is the universe expabding into".I liked it. I'm not an english native speaker.

I love just how this video is not only explained, but directed. The animation, sound design, visual effects.... Also WHAT IS THAT AMBIENT MUSIC. I REALLY WANT IT I This is one of my favorite videos.

Reason why I adore science (mostly physics) is of things like this. Can't wait to go to sixth form and Uni :)

It’s such an emotional, stressful, beautiful, scary feeling trying to comprehend coming from nothing… or when nothing existed… it’s like looking at the sun when you’re a child, and you have to look away… same thing with my brain when i try to comprehend the unknown, my brain has to look away it becomes too much

Only 3 seconds in and that quote already hit me hard, thanks

My theory, The universe is just one big baking loaf of rasin bread. Galaxies are rasins, the air inside is antimatter and the bread itself is space. The universe is transforming into a juicy loaf bread to satisfy the craving of a bigger, higher form of species, maybe celestial maybe gods...

This soundtrack is great! What's the title?

Love everything about this video and all the other ones like this thanks TED ED but from what I learned through your other videos and just the quote at the beginning of this vid is that there can be no physical understanding of what universe those 'brains' are in and what lies beyond that and so on. We have to find the answer spiritually. We must stop at some point and just go within. It's funny though how life is so paradoxical in that manner. The stuff we can see and touch shows us how not why. The stuff we feel makes gives us our own why in our own way. In the end just looking for the meaning and the reasons behind it. I'll stop there before this comment expands into itself lol.

I asked this EXACT question the other day. Glad there's a video for it

2:54 We know nothing Jon Snow...

It is expanding into itself. In higher dimensions you can expand inside your space and outside at the same time . Think of a Klein bottle. In higher dimensions it doesn’t need intersections. It’s a continuous flow from small to big at the same time

My brain melts under the influence of a non-asmr video. Mystery of the universe in a nutshell.

The only problem with the analogy of the raisins located on the surface of the bread moving apart... is that *_There is space outside the bread which allows it to expand._* If that bread were in a titanium container it wouldn't expand any further because the outer limits of the metal container would resist any further expansion. In order for outer space to expand within itself, it has to be expanding *_into a reality that allows its expansion without resistance._* So the original question has not been answered.

And this is why I want to pursue in astronomy!! :D 2:47 Yes!! Doctor Who reference! I mean... there are other Doctor Who references before in Ted Ed videos , but rarely.

D4C has the ability to allow parallel universes to coexist with the base universe

At the end of the video, I still don't know the answer, but this video was very interesting to watch. Thanks Ted-ed!

This makes me feel extremely humbling & insignificant.

This question bugged me ever since I read abt the expanding universe

What kind of insurance do you need to protect yourself against a universal fender bender?

Anyone know where to find the dreamy background music playing here?

Best explanation I've seen. Great work. Thanks Frank W. Canada

Question: If we are a part of the universe, is my body, house, earth, sun, and Galaxy also expanding? This video makes it sound like only the space between things is expanding. The raisins are a part of the bread/universe right? Would that mean they are both expanding together?

I always thought hyperspace was just a Star Wars thing but it looks like it might be a real. That's crazy T_T

I really liked this video. It was both interesting and relaxing.

The universe is just what our minds create when we try to observe beyond what it can comprehend. Hence why the two main limits in the universe is size (planck length) and speed (light). Our reality can't exist beyond these

Subhanallah

I believe we are being baked too... like that loaf of raisin bread. No wonder, why the world is warming up. :)

Anyone else just recently started binging Space videos late at night and haven’t stopped? Every night. Still being satisfied with what you’re absorbing?

I love how I didn't even look at this video yet and I know the true answer is "we don't know"

Notification :-Video related space Me:- just stop all ur work n watch ted-ed

I usually go too deep at thinking about this. When I think about the multiverse I start thinking about how did the multiverse came to be and my mind just explodes.

ted ed: gives anology of bread bread: clearly expands further out into the room ted ed: it expands into itself

2:18 did... did I hear that right

I’m still as confused as I was in the beginning. I guess my question will never be answered.

as i heard space is expanding unevenly, i am happy by this news , i am hoping "if carefully measured" next observation will reveal , that space is increasing faster between dense clusters , and expanding slower between less dense clusters .

Thanks for the video and nice background music

This makes my homework feel dangerously unimportant

I watched this video once and I thought I understood it. Then I watched it again and my brain turned into a puddle.

Where does a rubber band stretch when its ends remain in the same place? 3 dimensional space is expanding through a fourth dimension in the shape of a four dimensional fractal funnel, which both maintains 3 dimensional continuity and appears planar because we see along the curvature.

I fully understood... the first three words of this presentation. I am brill ! 😁

2:47 I SAW THAT TARDIS

Along with this video....I love Professor Dr. Tyson's quote at the beginning, from his latest book, Astrophysics for people in a hurry.....

thx for the Video & well done Animation!

I wonder what Multiverse Rules will the MCU use in their future movies? Great video, btw!!

It hurts that one of the facts is saying "We may never know what lies beyond the universe" since the universe is extraordinary expanding every second or less

If energy can’t be destroyed or created then how is the universe expanding Keep in mind that it takes energy to expand the universe (Seriously) somebody explain

I love TED-Ed. It’s not common here in Ghana

I always thought if we got to the edge in a rocket or something, that we would fly out of some giant kids science experiment 😂

or everything in the universe is getting smaller and smaller so we feel like everything is moving away
