What is outside of the universe? We know that the universe had a beginning 14 billion years ago and that it has been expanding ever since.
But something that is expanding should also have an edge, right?
What would you see if you went there?

When Im feeling lonely, I look at the sky, pick a direction, and wave. Because if the universe is infinite, that means there’s another me also feeling lonely and waving back directly at me.
Somewhere in the universe right now an alien could be looking in our direction wondering if there’s anyone else out there
❤
@@romanovmarkelyon1021it would be infinite aliens looking in all directions waving
Don't feel lonely - you are never alone
It wouldn’t just be one of you, it’d be an infinite number of you waving back from every conceivable direction. And an infinite number of you doing any other possible task in an infinite time frame. Every conceivable thing happening everywhere at every conceivable moment in time. Taking a foot step billions of milliseconds apart from an infinite number of you taking the same exact foot step in a moment in time divided into infinite parts.
The universe is growing so once you reach the edge you have to wait until the devs come out with a new update
The art direction here is so good, so much different scenes with varying styles and it doesnt ever feel boring or repetetive, it takes concepts and expands it, just like the universe.
Neat fun fact while im here : Astronauts took their name from latin : "Astro" meaning stars and "nautical" meaning sailor, so the full name means "Star-Sailor"
so maybe that's what influenced the visuals here ! its so neat and such a nice image and its executed so nicely, much love!
the molecule shown at 11:28 may have influenced the artistry a bit, too
It's actually greek but indeed, that's what it means.
@@Elloqus Yes ! Greek has Astron in which Latin borrowed it and made it Astro. Then Latin was made to make Astronaut, really cool how language evolves ! thanks for the insight

You should start your questions by reading the Bible. Most modern "science" is just made up crap.
Its a Wednesday in our galaxy

I swear I've been talking about this exact stuff for years. This and your video on time. I talk and I talk and some people get it and some people think I'm crazy... and then you drop a brilliant animated explanation and I show it to those people and they have a lightbulb moment.
I'm so glad someone out there is presenting these ideas with such high quality while also acknowledging the untestability of this science philosphy.

Nobody ever explains it simply. The universe is space and the big bang filled it. If you keep traveling, the stuff from the big bang runs out. But space continues. Just that there is nothing there. Space is nothing.
Uni uni Dr JJ😊
@@TheBooban the “Big Bang” is a model that describes when all matters of the universe were occupying an infinitesimal point which expanded very rapidly. It’s not “there was nothing and then everything happened”. Might as well go back to the religious idea that god created everything out of nothing which sounds more convincing than your Reddit atheism
@@therollerlollerman a point is nothing. Or what do you said an infinitesimal point is?
@@TheBooban “infinitesimal” means very, incredibly small that it approaches zero, not “infinitely small” or a singularity. There’s a reason your idea of a Big Bang was originally conceived by a Catholic priest because nothing -> everything is pretty much the Christian idea of creation. Much larger leap of faith than assuming the universe is possibly infinite because we just don’t know
When my kids were little , we were lying on the back lawn star-watching. I said the universe goes on forever and my daughter (8 years old) said “how can it do that?” . I said “well, what do you think would be at the end if there was an end?” ….she thought for a little while then said “ A full stop?” 😁💕
When I was 6, I asked my mom what the edge of space looked like but she just said “shut up with your nonsense”. I’ve waited so long for a proper answer
Don't sass me kid, just eat your Fruity Pebbles and off to school with you!❤
I'm sorry your mom shut down your curiosity

20 years later: bring that nonsense over here and we’ll tell you “IDK. But the answer will likely melt your brain”
Travel a few quadrillion lightyears up to ask your other mum, she'll give you a straight answer.
The fact that this came out only 7 days after the last one is quite impressive

they work on multiple videos at the same time, each video takes months, and they're out when they're ready, it's just a coincidence that they came out so close to each other

I remember reading something somewhere a long time ago:
"When infinity gets involved, possibilities become certainties"
no idea where you read that but its very true
Its probably not true. Think about how quantum mechanics work where things can truly be random.
Which is why the multiverse is so annoying whenever it's used too much in fiction
@@SamuelNoaGreenBut in infinity, there's a high probability of nigh everything.
Wrong... In the infinity group of natural numbers, each numbers occurs only once... The probability to "pick" one in an infinite number group is almost "zero". Because to calculate probability you need to divide by the cardinal, and one occurrence divided by infinity is... "Not a number".

Huh… did they edit the video or something ? That quote doesn’t seem to be there, but I feel like I remember it from the first time I watched it. Another commenter also mentioned a “you but with a funny hat” and I swear I remember that, but it’s not in the video currently either, so I’m not sure if I’m just misremembering or if the video actually changed. 😰
The idea that there could be endless galaxies, stars, and possibilities out there is both exhilarating and humbling.
It's so deep man! Why don't you ponder how many grains of sand there are at your local beach...

Right? I wasn’t particularly impressed by billions of galaxies either. I’m only a couple million years from being done exploring the Milkway, and by then I’ll only have a couple hundred billion left, which won’t take me very long at all.
I’m actually the version of myself wearing a funny hat.
The "Om Purnamadah Purnamidam" mantra from the Isha Upanishad encapsulates a profound philosophical and spiritual insight into the nature of existence, reality, and our place within the cosmos. This ancient verse serves as a profound meditation on the concept of wholeness, infinity, and the eternal cycle of creation and dissolution that underlies the fabric of the universe. Here's a deeper exploration of its layers of meaning and their implications:
This video brings to mind this famous Sanskrit mantra:
”Om purnamadah purnamidam purnat purnamudachyate purnasya purnamadaya purnamevavashisyate Om Shaantih Shaantih Shaanti.”
Meaning: ”What is visible is the infinite. What is invisible is also the infinite. Out of the Infinite Being the finite has come, yet being infinite, only infinite remains. Peace in my heart, peace with each other, peace in the cosmos.”
This mantra is a very profound verse from the Isha Upanishad (one of the ancient Indian texts that form part of the Vedas) and is often chanted for peace and completeness. It's known as the Shanti Path or peace invocation. Here's a basic translation and interpretation:
"Om purnamadah purnamidam purnat purnamudachyate
Purnasya purnamadaya purnamevavashisyate
Om Shaantih Shaantih Shaanti."
Translation:
"Om, That is full; this is full. From the full, the full proceeds.
Taking the full from the full, the full itself remains.
Om, peace, peace, peace."
Interpretation:
This mantra speaks to the completeness and infinite nature of the universe and the divine. The first part acknowledges that everything in the universe, both the unmanifest (nirguna, without attributes) and manifest (saguna, with attributes), is complete and perfect. It suggests that if something complete comes from something complete, it remains whole and unchanged. This is a philosophical or metaphysical statement implying the eternal, changeless nature of the universe's essential reality, despite the appearance of change.
The repetition of "purnam" (full, complete) emphasizes the concept of wholeness and infinity, suggesting that the ultimate reality or the divine essence is perfect and complete in itself, and even when it manifests as the universe, it remains perfect and unchanged.
### The Concept of 'Purna' (Fullness or Completeness)
- **Universal Wholeness**: 'Purna' represents an all-encompassing completeness, suggesting an existence that is intrinsically whole and interconnected. This challenges our everyday perceptions of separation and encourages a recognition of unity in diversity.
- **Infinite Nature of Reality**: The mantra posits that the physical and the spiritual realms are not disjointed but expressions of a singular, boundless reality. This realization prompts a shift towards seeing the self and the cosmos as reflections of each other.
### Metaphysical Implications
- **Unity of Consciousness**: It suggests that consciousness is not fragmented but a continuous expanse that connects all forms of existence. This unified field of consciousness underlines the non-dual nature of reality, where the observer and the observed are one.
- **Holistic Worldview**: Recognizing the universe as an expression of 'Purna' encourages a holistic approach to life, where the spiritual and material are intertwined, guiding one towards a more balanced and integrated existence.
### Psychological and Spiritual Dimensions
- **Inner Completeness**: The mantra counters the sense of lack or incompleteness many feel, suggesting that fulfillment comes from recognizing the wholeness within. This understanding can catalyze a profound inner peace and contentment.
- **Journey of Realization**: Spiritual growth is framed not as attaining something new but as uncovering the inherent completeness within, leading to a transformative understanding of the self and the universe.
### The Cycle of Creation and Dissolution
- **Eternal Continuum**: The cyclical nature of the universe, as alluded to in the mantra, highlights the eternal process of creation, preservation, and dissolution, which, despite its ceaseless motion, leaves the essence of reality unchanged and intact.
- **Perception of Time and Existence**: This cyclic view fosters an understanding of existence beyond the linear constraints of time, encouraging a serene acceptance of life's transient nature and the eternal continuum of being.
### The Invocation of Peace
- **Multidimensional Peace**: The mantra's closing invocation of peace encompasses inner harmony, peaceful coexistence with others, and a universal balance, reflecting a comprehensive vision of peace that spans personal, interpersonal, and cosmic dimensions.
- **Inner Peace**: Achieved through self-realization and the dissolution of ego, leading to a serene state of being.
- **Interpersonal Peace**: Fostered by the recognition of interconnectedness, promoting empathy and compassion.
- **Cosmic Peace**: A reflection of harmony with the universal cycles, embodying a deep respect for the natural order.
### In Conclusion
The "Om Purnamadah Purnamidam" mantra from the Isha Upanishad is a timeless beacon of wisdom, guiding individuals towards a deeper understanding of the universe's intrinsic completeness and the interconnected essence of all existence. Its teachings on wholeness, the cyclical nature of reality, and the multi-dimensional pursuit of peace offer invaluable insights for navigating the complexities of life, fostering a profound sense of unity, harmony, and fulfillment.

I am a geography major but i have always been very Passionate about astronomy and I have a theory, which I would like to get feedback on from someone from this field of study:
The universe is a finite sphere. think of it like the earth, every thing that exists are on the surface of the sphere. And the dark matter is the crust/mantle/core of the sphere. And the observable universe is like a continent on the surface and we just do not have the capabilities to see it through our current technology. OR maybe light it self has not been able to reach us till now. And the whole sphere is part of a system like our solar system. So, there is definitely multiverses.
My theory is based on the current understanding of our universe. As we can see, everything we discover is usually in a spherical shape and is found to be orbiting something.

A few centuries ago we were wondering what the edge of our world looked like. We keep coming back to the same questions, it's just the scale that changes
Centuries? Do you actually believe we have only known the earth was round for a few hundred years?
@@Rukushin does it actually matter? Did you not get the point of my comment?
Seems resonable, but I disagree. First, a few centuries ago, not many people believed there was an edge to the world: the now common belief that 'back when' people thought the earth was flat is incorrect; the Chinese, Arabs, Indians, and the Ancient European civilisations all understood that the earth is a sphere. Second, it is true, however, that people wondered about 'the edge' of space, and the scale of how big we imagine the universe to be has changed - what I'd say, though, is that not only the scale, but the whole conception of 4D spacetime has changed the 'shape' of what we imagine. Any thoughts?
Please we still have people out there that believe the Earth is flat..
Which is scary, or laughable, or both. I saw a classic miss-the-point flat earth 'explanation' recently: Our flat earth, you see, is like the PacMan universe; leave the screen-world on the left, re-enter on the right. Yeah, just... Well if that's the case, the PacMan universe is a cylinder, that is, a 2D surface curved through a higher, third, dimension - which exactly describes the surface of the (spherical) earth! You have to say, do they just not see this, or, as I suspect, they don't want to see it?@@frankbanales7419
I love subscribing to the idea that the universe is infinite. In a bittersweet way it makes me happy to think that there's other versions of myself that have experienced and done things with their lives that I couldn't with mine
See I have the opposite dread. An infinite number of other me out there that took the wrong turn and ended up tortured and murdered, or had a tremor when carrying my child and dropped them. Like if anything could happen and there is an infinite number of chances then anything that could will.
watch rick and morty and you'll have a different take. You'll likely hate most of yourselves.
There's only a finite amount of matter, we've deduced this by numerous experiments here on Earth. Finite matter means there's an insanely low probability of even a SINGLE copy of you existing (it means every single organism that has existed on earth up until this point would have to live identical lives, maybe they breathed a few more or less times, or sneezed fix or six less, but the point still stands, already crazy unlikely. Dupe-Earth would have to collide with Dupe-Thea to make Dupe-Moon and then make the same landforms like Pangaea, Gondwana, etc. and then the exact same genetic mutations would have to occur for EVERY SINGLE CREATURE.
Like, the fact that the ancestor of the animal cell even swallowed the mitochondria ancestor (which used to be a different organism, which the animal cell's ancestor could not consume) and formed a symbiotic relationship is already so unlikely that it probably never happened.
And even if there is one, I don't believe you are a very significant person, no? I haven't read your name in any history books, nor have I seen your face on the internet, nor have I heard of you at all. So even if there was a Dupe-You, would the history of Dupe-Earth change very much? Will you change the world, if you desire, or leave that to Dupe-You, who probably doesn't exist?
@@KING-hb5wh I mean it's not like anything authoritatively can be said about this since it's impossible for us to know so we might as well choose the interpretation that makes us the most happy.
@@KING-hb5wh I definitely won't 😂! I often think about my own Sci Fi TV series which has a multiverse part where my character visits his other versions and many of them are friendly.

Going to space must be one of the most incredible experiences ever. We as humans live for decades bound by the rules of our planet, but outside things just feel unreal and meaningless, knowing that nothing is quite like earth and that we won't ever comprehend the true extension of existence and life.
Human perceptions evolved on the ground with local purposes. I imagine when we travel into space, and experience something totally new, there must be a moment where no meaning can be placed by the mind. It's a _pure_ perception.
@@anonymous333It’s pure perception but it would be nice if we live on a populated galaxy.
[...] And then, suddenly, relief. No G’s. Zero. Weightlessness. We were floating.
We got out of our harnesses and began to float around. The other folks went straight into somersaults and enjoying all the effects of weightlessness. I wanted no part in that. I wanted, _needed_ to get to the window as quickly as possible to see what was out there.
I looked down and I could see [...] Earth.
I [...] turned my head to face the other direction, to stare into space. I love the mystery of the universe. I love all the [knowledge] that [has] come to us over thousands of years of exploration and hypotheses [...] but when I looked [...] into space, there was no mystery, no majestic awe to behold... all I saw was death.
I saw a cold, dark, black emptiness. It was unlike any blackness you can see or feel on Earth. It was deep, enveloping, all-encompassing. I turned back toward the light of home. I could see the curvature of Earth, the beige of the desert, the white of the clouds and the blue of the sky. It was life. Nurturing, sustaining, life. Mother Earth. Gaia. And I was leaving her.
Everything I had thought was wrong. Everything I had expected to see was wrong.
I had thought that going into space would be the ultimate catharsis of that connection I had been looking for between all living things-that being up there would be the next beautiful step to understanding the harmony of the universe. In the film “Contact,” when Jodie Foster’s character goes to space and looks out into the heavens, she lets out an astonished whisper, “They should’ve sent a poet.” I had a different experience, because I discovered that the beauty isn’t out there, it’s down here, with all of us. Leaving that behind made my connection to our tiny planet even more profound.
It was among the strongest feelings of grief I have ever encountered. The contrast between the vicious coldness of space and the warm nurturing of Earth below filled me with overwhelming sadness. Every day, we are confronted with the knowledge of further destruction of Earth at our hands: the extinction of animal species, of flora and fauna... things that took five billion years to evolve, and suddenly we will never see them again because of the interference of mankind. It filled me with dread. My trip to space was supposed to be a celebration; instead, it felt like a funeral.
I learned later that I was not alone in this feeling. It is called the “Overview Effect” and is not uncommon among astronauts [...] Essentially, when someone travels to space and views Earth from orbit, a sense of the planet’s fragility takes hold [...] “There are no borders or boundaries on our planet except those that we create in our minds or through human behaviors. All the ideas and concepts that divide us when we are on the surface begin to fade from orbit and the moon. The result is a shift in worldview, and in identity.”
It can change the way we look at the planet but also other things like countries, ethnicities, religions; it can prompt an instant reevaluation of our shared harmony and a shift in focus to all the wonderful things we have in common instead of what makes us different. It reinforced tenfold my own view on the power of our beautiful, mysterious collective human entanglement, and eventually, it returned a feeling of hope to my heart. In this insignificance we share, we have one gift that other species perhaps do not: we are aware-not only of our insignificance, but the grandeur around us that makes us insignificant. That allows us perhaps a chance to rededicate ourselves to our planet, to each other, to life and love all around us. If we seize that chance.

HE SAID THE THING!!!
At the highest level, this mirrors Minecraft. Think about it:
- Infinitely generating worlds
- Each generated world cannot interact with another
- The "true" World Border it at around 25 pentillion meters away before things start to break down
- During a normal playthrough, it would be impossible to explore an ENTIRE seed (i.e. world), let alone every single possible one
Just a thought
Dude how is it that Kurzgesagt always puts out banger videos on the EXACT topics i'm mulling over at work and at home.Thank you for your content, please keep up the great work!
4:30 I always knew Homer's theory of a donut shaped universe was intriguing! I might have to steal it.
Here are a couple more ideas that weren't mentioned. First the simple one: the idea that the universe has a kind of "edge", beyond which there is still space, but it's empty.
Second, the idea that the universe is *endless* but *not* *infinite*.
In this model, time and space are both endless but finite. Let's start with time first, because it is simpler: the universe is about 13.8 billion years old. Assuming that time had a beginning, the total amount of time is about 13.8 billion years. 13.8 billion is clearly a finite amount. But we never run out of time, so it is also endless.
In the same way, space begins as a single point and then expands outward at the speed of light, creating an unimaginable amount of new matter as it expands. After being created, space then expands uniformly as it does in the standard inflationary model. But, this endless space always has an outer edge. The new space being created today is probably absurdly dense, just as the very first space was. In this model, the universe is no longer 13.8 billion years old. Rather, 13.8 billion is just a lower bound; the universe might be 14 billion years old or 14 septillion years old, depending on how far we are from its original origin point. But since the universe is still finite, there may not be any exact duplicates of you.
@@davidpiepgrass743I personally like to imagine that the universe is finite and is a small part of something bigger, just like you are a small part of the Universe, or a single cell is a small part of you, or a protein is a small part of a cell and so on. And what the universe would be a part of is so beyond what our minds could comprehend, that there is no point even trying to imagine it. For all I know, the Universe could be infinite by our means of understanding and still be a part of something bigger.
Some say the earth itself is torus shaped.
It's not impassibole
that's fun how kurzgesagt's videos goes that far making you feel this existencial crysis, you're absolutely nothing compared to the universe, your existence doesnt matter at all. But then he says "oh dont worry, youre worth it 🙂"

Thanks for uploading, I needed my nightly dose of existential crises 😂😂
It’s funny that as I was watching this video, I took a second to realize, that the bed I’m lying on and the house I’m in, is part of this seemingly infinite universe and how ridiculously non important we are, but yet this is what we have and what we care about.
Is there really a universe, when all we see right now is the room were in and the sky we see? We know there is, but we don’t know anything about it, but yet we’re still a part of it.
Really shows how little we actually know about everything. It really gave a whole new meaning to “I know that I know nothing”
I feel you brother
Blud ur having a existential crisis
small does not mean unimportant, we are the most complicated thing we know
When I start considering the enormity and the general weirdness of the universe, I'm comforted by the words of Douglas Adams:
“There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable.
There is another theory which states that this has already happened.”
How is that comforting
@@silver_kitten Right?
I didn't get it
I see the universe as infinite, and I dont see the big bang as the beginning, but imagine the time before the big bang, the materials and the heat it gathered, or maybe previous big bangs that may have occured before it, or places of big bangs where it failed to occur, but helped set us up for later. We know so little, and are here for such a short period of time.
As far as we know it, time could not have existed before the big bang. There was no space before the big bang, and space and time are intrinsically linked.
Even if the universe is finite, time stretches ahead and behind this moment infinitely. 🤯

If I understand correctly, Minecraft coordenates are hardcoded finite, I believe it has the size similar to the surface of Neptune (patch 2020, I don't know if now it's bigger, but sure with some coding it can be bigger)
@isnowinchainswe're talking conceptually here, not literally. it's physically impossible to create any program that proceeds infinitely, let alone a Minecraft world. but i'd recommend anyone spent some time reading minecraft.wiki's articles on the modern farlands (post 1.8) because they're insane.

Plot twist: same thing happens in "real life". Simulation fails.
Space Engine? Is it like that new space game Starfield?
@@inc2000glw It's a simulator. They used to have the legacy versions available for free on their website but the page is a 404. It's on Steam otherwise. I enjoyed setting my speed to the speed of light and marveling at how slow it is in the vastness of space. There's also Universe Sandbox which is more of a physics simulator that lets you edit and create objects, trajectories, etc while Space Engine is less interactive but more accurate to real life. Plenty of procedural generation but you can visit I think damn near every object we've discovered in the generally right place and the general structure of the universe is accurate.
Always loved your content
I always thought of this possibilities, i'm happy that i'm not the only one.
I find the potential of an infinite universe with infinite copies of ourselves quite mind-boggling but strangely plausible. It's riveting to think about the concept of finite options yet infinite combinations in a limitless universe. Even more intriguing is the possibility of a hyperdonut universe and the complexities that it could entail.
I guess the easiest way to approximate a visual understanding of hyper-spheres or hyper-donuts is the Möbius Strip
Except a Mobius strip only works going either forward or backwards. Turn 90 degrees to the side and you find an edge. On the inside surface of either a donut or a sphere you can move in any direction and never find an edge.
@@rustknuckleirongut8107what you know about a Klein bottle

@@rustknuckleirongut8107 You are not in two places at once, we just don't have the ability to represent its fourth dimensionality properly in three-dimensional space. Those positions on the surface are not actually connected, they just look like it in any representation we can draw.
@@Twisted_Code This is why the donut makes more sense as an example it does not need to be represented in a way that makes no sense in three dimensional space.
I love it when your channel conducts thought experiments like this. It's always very interesting. In fact, it doesn't really matter whether our universe has boundaries or not. Due to the limitations imposed by the speed of light and the expansion of the universe itself, those living organisms that are lucky enough to exist will never be able to get beyond the limits of the world they can see. So there is a kind of boundary, and nothing can be done about it. Of course, I would like to study the real boundaries of all things one day, but it doesn’t seem like this would be a feasible task for people.

ive been wondering about these exact things since i was a little child. i would always ask my mom how big the universe is, is it infinite, how is that possible, how does time work and things like that. now im 16, iwatched the netflix documentary about infinity and i came up with a theory that satisfying for me. i have been very busy with school lately (for the past 6 months) and now i finally have 2 weeks off, and i can watch this video and go back to just thinking about the universe and about the things that nobody knows the answers for. feels good to be back.
i just finished the video and my theory was said. feels good that i came up with my own theory, and it was confirmed by kurzgesagt that it might be correct
last words: and I still have 0 beaches
@@user-lj6ni8hv5bsame here my theory was said too.
@@user-lj6ni8hv5b 😭😭
A constant in the universe is people at 16 thinking that they have worked everything out 😂😊😊😅
*"This edge is more like an edgin time"*
Never thought I would hear kurzgesagt say edging time.
The obvious answer to me is that we're inside the event horizon of a singularity. What we see as "outward expansion" is just space-time being stretched faster than light between the exterior universe and our universe; there is no "barrier" per say, in that outside the "edge" there's still "universe', but it's not our universe.
Those transitions at the end were so smooth. This is high quality content.
I think it's the highest quality content all around on youtube: information, writing, editing, literally everything is as good as it gets
Love the Truman show reference 1:45
I subscribe to the theory that "The Universe" needs to be split into two terms: "Material Universe" and "The Empty". So together with the Observable Universe you have 3 layers of an Onion.
- First layer is what we see and what concerns us - Observable Universe (explained very well in this video).
- The Material Universe is comprised of everything from the Big Bang. Stuff that we see and don't see (dark matter/energy). As well as stuff that's so far away and forever expanding that we will never see it. However: A finite amount of "stuff" was ejected from the Big Bang and no new "suff" can be created. It's all out there and finite.
- The Empty then is the last layer - the space that no matter and not even light has reached yet. But it will in the future, because of expansion. But it's infinite, so it will never fill up completely.
So given this theory if you travel in a straight line like in the video, you won't be back where you started, because it just keeps going until you 'reach' The Empty (and by definition it won't really be "The Empty" with you in it. So you can say you can never reach it)
And you probably won't run into yourself and you can even count the amount of planets, stars etc. That you run past before reaching a point where there are none, because the amount of particles that came out of the Big Bang are finite. You can't have infinite versions of yourself, because there were finite lego bricks in the lego box before it exploded and sent them flying far-far away.
learned quite a lot, took a break to think about it for a moment. Then realised i'm only 2 Minutes in... Wow. Thanks to all of you who make this possible
6:10 This. This is the stuff that breaks _my_ brain. Infinity doesn't bother me; I'm perfectly happy imagining a universe that extends in all directions with no end. Even 4. 11. 27+ dimensions "feel"I acceptable to my mind, I can understand them even if I can't see them directly.
It's the transition from non-existence to existence that my mind can't handle. Why is there anything instead of there being nothing? If something could happen in nothing that made it not-nothing, then it can't have been nothing to begin with!
Every time I try to think about this it feels like my mind is looking at a light that's too bright and has to look away.
I read a philosophical explanation that basically said: there used to be Nothing, and Nothing is like a vacuuming force: it turns other things into Nothing. However, as soon as Nothing started existing, it “nothinged” itself out of existence, thus becoming Something. It’s a fun explanation and very elegant. It’s not very scientific, but i also used to wonder about this same exact thing until I read this fun explanation.
9:21 subtle reference to Bioshock? "There's always a lighthouse, there's always a man, there's always a city."
I was looking for this comment!
Hi Kurzgesagt,
I’ve been a fan of your videos for a long time across different accounts and I’ve always loved your videos! I especially love the scientific and philosophical research in the content and all the artistic and musical dedication. In general, your work has been wonderful and I hope you continue to keep doing what you do!
However, I have some feedback that I would like to state regarding your thumbnails, titles and some of the recent content. As has been documented in a few Reddit posts already, it’s been noticed that the original, very creative and introspective thumbnails and titles for certain videos have been scrapped and changed for more clickbait and less authentic versions (for example “What Are You Doing With Your Life? The Tail End” turning to “When This Number Reaches 5200- You Are Dead!” (Or something along those lines), and “You Are The Dream of a Dead Universe” to “We Did The Math- You Are Dead!”, as well as their thumbnails). While it is understood that the algorithm will recommend videos containing these less authentic methods of advertising, I feel like this is really a waste of talent from the artists as well as the old charm of an educational and deeper outlook of your videos. The channel is beginning to feel like a content farm similar to Bright Side, which is a bit saddening because of how much effort and love put into these videos made for smart content and the history with its audience. Sometimes they are directly misleading, for example “Why South Korea is Dying Out” has relatively little to do with the content of the video itself as it mentions it perhaps once or twice throughout the whole video.
I just hope that we don’t stop the quality because of these facts and that the videos themselves don’t get affected as well.
Maybe if it isn’t possible to keep the titles and thumbnails, would it be possible to at least make a video explaining the changes made recently by the channel? Just to give some more justification to the artists and authenticity of the messages you purvey and explain to the fans who have gotten disappointed due to them.
However, I do understand the reasoning behind it all and I will support you no matter your publicity choices because I still love your content and they provide so much insight and information, especially to our younger generation!
I just hope this message helps bring to light some of the problems some of us have noticed and helps you improve and keep up the awesome work!!
Thanks for it all, sorry this message is so long, and have a good day!
This change is because kurzgesagt is funded by bill gates and other billionaite beaurocrats, who use theyre channel to push certain ideas to the people, and of course, theyre not transparent about their actions. Search it up kurzgesagt bill gates foundation, a youtuber made a great video about it
The name of the video you should see is how kurzgesagt cooks up propaganda for billionaires, by the youtuber - the hated one.
Honestly I blame the algorithm (which is pointless I know because it's just a computer program), because it's created this system of clickbait over quality. Something that takes hours to create but has a nerdy/weirdly scientific title will get a lot less views than something that takes minutes to create but has a fake clickbait title
Damn that’s a lot of words

I truly enjoy Kurzgesagt videos! They are great at presenting questions of interest. Personally, I believe in a universe of infinity and eternity. I base my personal belief on my perception that any boundary is just that, and that in all probability there is something beyond which I can't yet perceive. But if Kurzgesagt videos have taught me anything, they have taught me what I perceive is just that. It's what I perceive and that perception can be finite.
Branching from the ideas of relativity, we may be in an expanding finite set, with the accelerated expansion of spacetime stemming from fractal, infinitesimal edges of event horizons as the gravitational forces beneath them warp towards singularity. And because all perspectives in all frames of reference in general relativity are assumed to be constant in experience, it could imply that no matter where an observer or object is relative to its environment, it's still at the center of spacetime from its own perspective, which is consistent with the notion that flying in a straight line through spacetime will eventually bring you back to the same position, though you'd have to beat the accelerated expansion of spacetime itself.
The end is never the end is never the end is never the end is never…

Look it up.
Oh, and keep in mind that while you, the mass-particulate astronaut, are traveling as fast as you can in order to reach the "edge" of this beautiful mass-particulate universe of ours, "time" is passing (as you are moving slower than the "light waves" you are perceiving it all by means of).
