Kurzgesagt never fails to give me an existential crisis.

"Me missing the bus was already predetermined since the big bang" Say that to your teacher in school lol

5:37 I was SO relieved when he said “Except, quantum stuff is ruining everything again”

Something I said in middle school: “you can’t change the future because changing the future was already a part of the future.”

The most unrealistic part is that I have a future 💀

"Weird mix of duck and mammal that makes no sense." It's such a way to roast a platypus.

Love the Don't Hug Me, I'm Scared reference!

really like when someone explains about confusing time things, and I fractionly understand it little by little

Excellent video. Will have to watch it again yesterday, since I've already seen it tomorrow.

Hard to believe this video is from 10 years ago time flies

The past doesn’t exist, the present is the past, the future is the present.

I've always thought of time in the same way as a book. The story exists from beginning to end within the pages. But we can only experience it one word at a time in the same way we can only experience time itself one second at a time. An unread book holds surprise and the unknown, but the beginning, middle, end, and everything in between already exist. We see our lives as having a beginning, middle, and end, but we really have no way of knowing where our "blink and you missed it" existence is in the bigger picture of beginning, middle, and end. I guess skipping ahead and reading the ending would equate to time travel in this analogy, but only a complete a-hole would do that.

I love how you missing the bus is knitted into the narrative of this video. As you have missed the bus, are about to miss the bus, just missed the bus, will miss the bus, all at different points in the video

1:08 the Don’t Hug Me I’m Scared reference is awesome 😂 love those little things hidden in there.

I don't feel real after watching this video

3:57 i love the twin peaks reference

You finally made this video . . . it's about time!

The fact they can use all of these trademarked characters to illustrate their ideas makes it all feel so much more premium

now im just way more confused than i was

In the middle of reading The Order of Time by Carlo Rovelli. Today I just got out the other end of the free will existential crisis part, so I’m a bit more prepared for this. I personally think that the static universe explanation might actually make sense; I think that there might be a way to determine quantum decay and we might just not have the ability to look hard enough yet. We thought there was nothing inside a particle, and Lo and behold, quarks. I just think that the eventual explanation is gonna be so convoluted and perhaps even turtles-all-the-way-down ish that it’s gonna be a minute before we know. Remember guys, even if every one of our actions are predetermined, we still get to have the experience of life. Its ups and downs, its beauties, its tragedies. Wanting to have a chunk of it be fully under your control could be, while reasonable at best, greedy at worst. And those determinations are still, in essence, part of yourself. You are a collective of atoms and energy. If a decision comes from within that bundle of atoms, it is still your decision and you can and should be proud of it. Existing is clearly better than not existing due to your positive effect upon this reality and the experience of the world around you. We are in the ice block; we look around and marvel at its crystalline structure. There, in the enrichment of the consciousness, there is meaning. But what do I know? I’m some 16 year old on the internet. If you have any ideas, or critiques, please tell me. I want to learn, need to learn. And I can’t do that alone.

That "don't hug me, I'm scared" reference at 1:07 hit me like a freight train lmao

The fact Kurz spent a month travelling to the future just to educate us about it is insane dedication

I've been trying to explain this to people and nobody understands. Thanks, guys.

This video is amazing. Thank you so much for your works!

"Don't Hug Me I'm Scared" reference caught me off guard 😂😂

The fact that this was explained very very well in a Ben 10 episode is still amazing....

1:37 the funniest thing I've seen in a long time!! :DDD And so absolutely revealing message! Thank you.

I was really really not expecting to run into any Space Dandy reference any time soon, and i feel so glad that i did. Also the video's great :]

everyone's talking about the animation, but the soundtrack is amazing! everything leveled up! congrats, i got an existential crisis again!

The talent of this crew, just amazing.

What a concept and a brilliant explanation!

I watched this video 20 years ago n still love it

Cant stop it. A small Dad joke on this. One fine day, the Past, Present and Future walked into a bar. It was tense. 😅

When I was 5 years old I had this feeling everything was predetermined and I was just watching it all happen so I tried to do things that were unpredictable in an attempt to break the universe, but I quickly realized I couldn't prove it

I came up with the basic theorea first. Love the content, plz make more

2:00 thats what i was thinking, like when someone goes to sleep they probably are experiencing the next day while you are still trying to go to sleep

Yay for the "DON'T HUG ME I'M SCARED" reference! You even showed the creepy Clock Guy when you said the line! ❤❤❤

These videos are the only thing that calms me down. It's nice to know how small my work problems are when im apart of such a large universe.

I understood time so clearly❤. Tq so much

10 years and still this video is amazing.

Love the "Don't Hug Me I'm Scared" reference at the beginning with Time !! EDIT: Damn glad to see so many people of culture in here

Yay, now I can question my reality and not know for certain whether I really exist. Thanks Kurzgesagt! 🎉

Epic Production 👍🏽

Thank you for including paradot

It sounds like the problem with the 3 alien spaceships thought experiment is that the "instantaneous internet" breaks causality in the same way that time travel would.

“The conception of “time travel” is predicated upon the notion that the future has already occurred and that the past is somehow still accessible, which begs the question, where is time being “saved”, and what IS “time” if not a mere abstraction?”

This video reminds of my two favorite books about time. "Laminated Spacetime" by: Barbara Dewey and "The Arrow of Time" by: Covey and Highfield.

"So what you think is 'now', is really only your 'now' - there are many different 'nows' in the universe, and all of them are equally real" - my mother claiming dinner was ready when I was a child.

These animations are outta control , over the years I’ve seen these people level up heavy

Amo este canal, esperando que este video sea traducido al español!

This video gave me goose bumps at the end

never has the phrase "Except! Quantum stuff..." made me feel so relieved than at 5:38 surprised myself.

Interstellar moment, I love overly complex explanations of time!

this fascinates me love it

Wow! It all makes sense now!!!

Very much appreciate that Peridot cameo at 3:43

Time is definitely one of the most complicated, weird and difficult things that one could possibly try to wrap their head around, so Kurzgesagt attempting to simplify and teach it ''in a nutshell'' (Exactly what they do best) is definitely very daring and commendable. [Edit 1 month later] wow has this comment gotten popular, why did I just now realise it's been saying ''Comlicated'' this whole time T~T

In the words of Dr Hillier, the future is irrevocable, it's already there, it cannot be changed

There are so many references in this episode! Twin peaks, don’t hug me I’m scared, space dandy, Star Wars, Steven universe, the black lodge, probably some I didn’t even notice…

I love the don’t hug me I’m scared reference, I spent to long laughing at it

great job explaining the 4th(time) dimension like a literal dimension in space

7:20 Ah Kurzgesagt. Putting some of the grim realities of life in an engaging, relatable, clever, iconic, & ironic way, et al.🎭

I did not expect a Don't Hug Me I'm Scared reference at 01:10, that clock lives in my head rent free (I would like to wear it on my rizd).. beautiful work as always Kurzgesagt.

I was watching this while waiting for the bus, so the “stop watching youtube to not miss the bus” made me look up so many times 😂

This left more questions than it left answers 🤯

So interesting, I feel like my concept of time is memories I'm experiencing

1:06 I loved the Don't Hug Me I'm Scared reference! 😅

"Most people think Time is like a river that flows swift and sure in one direction, but I have seen the face of Time, and I can tell you, they are wrong. Time is an ocean in a storm." - from Prince of Persia, the Sands of Time. Makes more sense to me now, after 21 years.

3:46 love all the references, but the best one is obv the dhmis one at 1:06

That Don’t Hug Me I’m Scared reference was so unexpected! Love it

this guy makes thing simple and complicated at the same time

“Ok. This is a lot... Imagine three spaceships 1 million light years away... “

Love all the easter eggs! Miss Minutes, Yoda etc

My favourite KZfaq channel from now

1:08 Props for sneaking in Tony the talking clock! If you know, you know.

The idea of the Growing Block can be super inspirational. It should be a poster with it saying something like, "The Block is still growing, lay the story". Idk, but I would buy something inspirational and sciency

I think personally, due to relativity principle, you can say that YOUR "now" is valid, so does your future and past. But, because this is YOURS, meaning while you expirience it, the you of the present is feeling both the future and past, while other, with their own relative perspectives, can only "know" one of the "nows" of yours, as the same time like the expample shows, the time diffirences while you travel from one point to another in the block of time.

“People like us who believe in physics know that the distinction between past, present, and future is only a stubbornly persistent illusion.” -Albert Einstein I'm glad you're doing this one, b/c a lot of Science YTers are pushing Determinism (a religious philosophy) because they fundamentally misunderstand Relativity, and Physics (yes, even Physicists like Sabbine Hossenfelder and Niel Degrasse Tyson: both of which work in highly-predictable fields, and both of which constantly exhibit misunderstandings of Quantum Mechanics, usually claiming something like 'under no circumstance does quantum mechanics effect macro physics" which is demonstrably false. the "Newtonian physicists Hate Heisenberg" meme goes back to before most of us were born for a reason) I'm in the camp of "Time isn't a thing at all". Time cannot be isolated, quantified, nor measured directly. We track it relative to how we experience the world around us in our meat brains, and all attempts to scientifically quantify it have failed, falling back on relativity (and note that a Cz atom will take longer to vibrate X number of times in a stronger gravity well or moving at higher velocity than in neutral, "flat" space, but 2 atoms in different frames of reference are still existing simultaneously). Matter/Energy exist in, and deforms, Space: That's it. Time only ever comes into play when *tracking progression* of something, but is completely unnecessary to most equations. *NOTE: "Speed" as in the 'speed of light in a vacuum' is an expression of a universal constant of energy and a measurement of Velocity and/or Inertia. We *EXPRESS* that with distance over time for no other reason than that is how we understand that concept in daily life. m/s is directly descended from MPH, conceptually. We use time to understand the world around us b/c that's part of memory, which is a part of pattern recognition: which is itself an evolutionary advantage. Relativity is, perhaps, better thought of as a sort of "resistance" on Matter/Energy (which are one and the same, EM or ME for short) due to the Gravity Effect. Strong Gravity effect things by distorting Space, thus altering the "Medium" through which they're moving, kind of like thickening water would slow down something moving through it would, except there's no matter there for them to impart energy into, so they move more slowly, but don't slow down b/c there's not physical drag: they just move more slowly given the same amount of energy. so, there IS NO PAST, *NOR* a future. we can imagine and extrapolate and remember, but a memory is something that exists now, it's not the past itself, and only the simplest and most immediate predictions have any hope of being accurate, but they, too, only exist NOW. You might say, "but we know a thing happened b/c we saw it, and remember it, and we see it's effects now!" well, that's because, as per the Law of Conservation, that which Was, has now changed. So if a rock was hurtling through space and hit something else, we do know it happened and it did effect what it hit; but that impact no longer exists, there's a crater, and maybe something else hurtling through space with that same energy. All the involved ME is there still, but the EVENT is only a memory, and only the MEMORY exists now, the event no longer exists, as that would violate the Conservation Law. if you could freeze time like a movie, you'd see everything frozen in place, but in that instant, those "frozen" objects would contain all of their matter *and energy*... including their Kinetic Energy. so an asteroid has inertia, and that inertia has a vector in the here and now, if we track it, we can extrapolate it's path back and forth, but *Right Now* it is Where it is, and has the Energy it Has, it is not also where it was and where it will be.

That don't hug me I'm scared reference was golden

When I was a kid, I thought a lot about the phrase "time flies when you're having fun". Like if I spent a whole day at school while my friend cut class and went to an amusement park, the day would feel significantly shorter for them because they're having a blast and I'm bored at school and time is dragging. So, the day flies by for them, each hour feels like 20 minutes, meanwhile the day is dragging for me, each hour feels like 2. So, I thought to myself: "in their head, the day is probably already over for them, and they are getting ready for bed, meanwhile I still have an hour left of school. So, am I in the past? Is everyone's 'now' different? Has anyone thought of this before? Why is no one talking about this??" And then I learned about the theory of relativity. So basically, I'm Einstein. Thank you for coming to my Ted Talk.

I remember being in 7th grade and zoning out and thinking about perception of time and consciousness. I'd thought "What if everyone from the past, the present, and the future are perceiving time at the same time?" I don't know how to explain my silly little daydream, but when you think about your existence at the moment, you obviously think of yourself in the present. You don't really perceive the future as an existing being that's looking back on you. People from the past probably thought this way too, because there's a moment for every person to be living in the present. If consciousness goes away after you die, then does your consciousness exist permanently in the present? And if that's the case, are historical figures perceiving their lives at the same time? Or your future descendants? It doesn't really make much sense, but I was bored at a club meeting and decided to give myself an existential crisis.

The way I have always seen it, the big bang was like a bubble bursting. Everything happened all at once and it's already over. I think of that whenever I'm having a bad day and it cheers me up

Dhmis reference appreciated

3:50 The amount of amazing references here is astounding.

Wasn’t expecting to see my boys Kirby and Bandana in this video. Love them!!! ❤️

When I was facing hardship with my thesis I have always thought about this concept that past, present and future exist at the same time. So I would tell myself that I actually have completed my thesis.. so only thing left to do was to wait for that moment in the future from my perspective. Of course for this to work one has to be 100% sure that the task at hand will be completed one way or another.

this stumped my understanding. like what the hell? your guy's ability to explain overly complex notions are laudable! every time you guys introduced a model of time of the universe, it always made me question stuff like "is the future already written then?!" and you guys actually do cover it afterwards. predicting the stream of human consciousness is a godlike skill so I applaud y'all once again! now i'm going to debate the paradoxical contradictions between the ice block model and the growing block model lol because either don't complement each other at all...crazy stuff...

One thing that helps the mental mapping of how there can be "so many nows" and also how some "nows" are in others' "future" is that there is a speed to causality.

Makin me shiver 😮

My mind just exploded with a thousand questions and ideas. Its like being awakened from a dream.

Every single Kurzgesagt video has me questioning my existence from the first second, and right at the end it tells me it will be okay

1:08 I saw the DHMIS (Don't Hug Me I'm Scared) reference coming but it was still a pleasant surprise

I'm looking forward to having really enjoy watching this now. 😵‍💫

amazing stuff. so scary. so difficult to comprehend.

What I find so fascinating about relativity is the sheer amount of time travelling paradoxes you can create, and how some of those same paradoxes might interact with each other

Love how these videos always make me question reality even more than I already do

I agree on this theory. That’s how you get déjavu. I had many personal experiences to support this theory. Like once i was driving early in the morning where the roads were quite empty, i was speeding on the speed lane and I somehow got distracted with some heavy thoughts. Suddenly something made me to cone back to reality and concentrate on the road and i slowed down a little bit. Few seconds later there was a flipped car right on my lane where an accident occurred. If I didn’t slow down i would have gotten into secondary accident which would have costed my life. Maybe in future which in this case i would have already gotten into an accident and i somehow felt it. Idk how to explain because I’m not a physicist. But i always had many theories and interest in this field.

When you are happy time runs faster than when you are sad. Indeed relative - not just based on your physical speed, but your perception :)

I wish to add that: even if time is already written (and even with quantum mechanics it's simply random not 'free will') it simply means that, in exactly the same situation, and as that exact version of us, we will always make that same decision, but even if that event will always happen and the outcome will always be the same it is still our own decision, our brains deciding the course of action to take, which (if you don't believe in anything beyond reality like souls) is all that would happen anyway. Essentially, the predetermined future is simply a projection of the decisions you will make, it doesn't nullify that you have made them, it just the when of the matter that's blurry.
