I can't express how much of an impact 1:07 was for me. I was looking at my plate cutting my dinner while I listened and when you said "The past is far behind us," I froze thinking "the future doesn't exist" and when I heard you say it, looked up and saw that GOD DAMNED CLOCK the shudder I had shook me to my core. Top writing. I will later say how I enjoyed the rest of the video.

this video is about false understanding of relativity and a total nonsense. an alien 1 is actually in the past and an alien 2 is actually in the future. there's no 'different' 'alternative' 'nows'.

Its an apt analogy. The physical processes in our brains that create consciousness happen FAR to slowly to be measured in planck time. Meaning consciousness lags behind the "current painting" because our minds are nowhere near fast enough to perceive each frame. Consciousness has "missed the bus"

Gotta respect the platypus, after all, I do believe it is the only mammal that lays eggs and doesn't give birth to a live platypus. Not that other mammals give birth to live platypuses, platypae? Not sure which is correct in the plural sense, but anyways, I only meant they don't give birth to live young like other mammals. I think they're kind of cool.

I hope you'll see that you don't need quantum stuff to know your mental process still exist, if that's the part you're afraid of. Like, you can agree that your "today" will eventually be your past, and that for that futur you, it has already happend, and they know which choice was made. But it doesn't change that there was a thought process, a decision, even when the output is already known.
@@lucdombar4527 Thank you. Searched the comments just to find someone else that disagrees with Kurzgesagts interpretation of free will. I hear it so often and had yet to hear someone question it, even though it seems so obvious that just because your decisions are fixed does not make you unable to make decisions. You just will always decide in the same way that the same version of you in the exact same situation would always decide.
@@riliash > You just will always decide in the same way that the same version of you in the exact same situation would always decide. that's actually a really nice way to put it.

This is actually one of the philosophical questions I find myself pondering at various points in my life. There has been a handful of events in my life, that I’m sure others will be able to relate to, where a seemingly random frustrating or inconvenient event has made me late to go somewhere, however when I finally leave I find out that there was a devastating car crash that happened roughly at the exact time I would’ve been in that location if I’d left on time. One that will always standout to me was when it felt like the “universe” was trying to stop me from leaving my home or possibly delaying me so time would line up for a crash, i.e. back to back inconveniences - my jacket got stuck in the door as I was leaving, then my key lanyard got caught on the door handle, and then my seatbelt got twisted and i had to fix it before i could leave). Once I finally left slightly later than I usually did, a car ended up backing into my drivers side door in a parking lot and that was my very first accident ever. Looking back at things like this, to me, some moments in life certainly FEEL like the future has already been written and that events are going to happen on a schedule. Of course it could also be random and things just happen out of nowhere, but the times that life seemingly did its best to either delay me from getting in a car crash or caused me to leave at a time where the car crash actually happened stand out in my mind. My mom always describes it as a guardian angel when something delays you and to be aware of what’s going on more than usual as it could be trying to warn you about something about to happen, maybe time works the same way or is the guardian of our lives. Just something I find really interesting to think about, I hope others can relate ❤

“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?”
Very true. The only reason I give any credence to the theory though is bc time travel is indeed possible. So if you can travel through time then perhaps that point in time before or after your own exist at the present. Otherwise, idk how the past or future could be accessible
AsSalam Alaikum, peace and blessings of God be upon you and all brothers and sisters, children of our father Adam (as) and our mother Eve (as). Dear brothers and sisters, usury (interest,loans,debts,inflation) has destroyed mankind. Kindly read these verses. God bless you. --- Those who consume interest cannot stand [on the Day of Resurrection] except as one stands who is being beaten by Satan into insanity. That is because they say, "Trade is [just] like interest." But God has permitted trade and has forbidden interest. So whoever has received an admonition from his Lord and desists may have what is past, and his affair rests with God . But whoever returns to [dealing in interest or usury] - those are the companions of the Fire; they will abide eternally therein. God destroys interest and gives increase for charities. And God does not like every sinning disbeliever. Indeed, those who believe and do righteous deeds and establish prayer and give zakah will have their reward with their Lord, and there will be no fear concerning them, nor will they grieve. O you who have believed, fear God and give up what remains [due to you] of interest, if you should be believers. Quran 2:275-278

@@viniciusdomenighi6439 Wait, are you saying the quote from a fictional person from a video game in a fictional world, isn’t 100% accurate to our world?!
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
I think the universe prevents paradoxes. Time could very well exist in these blocks, but when quantum mechanics comes into play, prior to the collapse of the wavefunction by an observation, the universe splits into the many worlds. Perhaps t=0 was a single page, but for every plank-time after t=0 there would be an exceptionally large number of pages to represent each of the possible universes. To break out of science and into my personal philosophical and spiritual beliefs - there is an untestable but fundamental analog of the fundamental quantum fields, this analog upholds consciousness-exclusive information like qualia for example. I think the overall consciousness-field is literally in-and-of-itself conscious and capable of universal scale choices. I think that consciousness-field (which I consider as deity-like) is the universal child - but he's not drawing the pages, he's picking which pages go into the book (or books if time travel were to become possible). The consciousness-field exists across time from the big bang to "Prime-Time," which would be defined as the time in which no conscious observer has yet born witness to collapse the wavefunctions.
@@mzaitealthough this isn’t really a paradox assuming that light travels at the same speed both directions which is always assumed when talking about the theory of relativity
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
Agreed, especially the fact that they've managed to discuss both determinism and uncertainty as literally opposing ideas in a single yet logically coherent video!
@@golamrasul9887I truly don’t say this to be argumentative, it’s a genuine question. Absent religious reasons, which I don’t think you’re getting at here (and I think/hope we can finally start to write off the opinions of the religious as an anchor on progress, they’ve been the loudest voice in the room and the legislatures, etc, for far too long), why do people cling to having free will so badly? It’s not like once we discover or accept we do or don’t it changes. If we don’t then we never did and things would *seem* largely the same, except maybe we could be more compassionate. If we do then we always have.
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.
Yea. Causality "spreads", at the speed of light... Which begs the question... in a sci-fi setting, could reality actually be rewritten? If a "causality wave" moves at the speed of light, would an "anti-causality wave" be able to cancel it impacting with the first, canceling the event retroactively? Maybe not where the event already happened. What about canceling its spread... ?
@@sethheristal9561 Yes. Instead of thinking in terms of time and the speed of light. Think of reality in terms of MATTER and CAUSALITY - like dominos interacting with each other. Light moves at the speed of causality. And obviously when you move at the speed of light, YOU are moving at the speed of causality. But, you are moving at the speed of causality right now. Everything does. Your "particles" are currently whirring in orbits at the speed of causality. If you get in a spaceship and approach the speed of light, your particles move through the fabric of space, your causality is iterating through the fabric of space, slowing down the orbits of your particles because the speed of causality is constant, therefore it must be distributed between orbital and lateral motion. So, your orbital cells slow, and your thinking slows, but you are flying faster through space. So, stop thinking of it in terms of a clock. Think of it in terms of matter. Time is a tenuous concept that humans made up. A clock is just a spring under tension or an oscillating block of quartz anyway. Scientists have tried to track time accurately using cesium and found that the clocks diverge just by raising it off the floor. So how can you ever expect to track now? The concept of time understood by the general population is very primitive. We might as well believe we can "measure time" using ocean waves.
Perhaps it was already made, but you're only now experiencing it. If this was true, then you already have experienced it, just not relative to now, until now. So I ask, did you even really wait at all?
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.
Well I’ll be damned, I had similar kinds of thoughts like that myself from time to time. Still do Strange thing is I even saw a brief 1 second glimpse of my own future once too. Didn’t realise until years after I dreamed it but it was exactly just as I had seen it. I haven’t had any since but perhaps that will not always be the case. Makes you wonder doesn’t it? Is the future set in stone and strange fluctuations in the fabric of spacetime allow some premonitions, was it a bubble in the fluid ‘present’ allowing a brief glimpse into a possible future? Are dreams even fabrications of the mind, or are they windows into viewing possible moments in alternate realities and parallel universes. Who knows
Strangely enough yes i had this thought that time moves differently under certain conditions. Are we all in sync or do we all have a static amount of time that gets spent at different rates? Do too much of one type of thing using up time faster and reach the end of life sooner etc.
The way we experience time has a lot to do with our mental state. For sure time does not pass equally for every being in the universe. I don't know how old you are, but 5 years in our childhood seems to take a lot longer than 5 years when you are an adult for example.
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
BRO!! I WAS JUST THINKING THAT!!! (You read my mind) Great minds think alike! Yeah! I would totally buy a poster like that! For me the ideal slogan would be: The Block grows, with or without you, but only you get to decide how. Stack your bricks, or someone else will stack theirs. 🧱 I don’t know, I think the Universe favors those who make the first choice, though I still strongly believe you have to think things through first, you can’t just keep worrying about the end result forever, either you’ll succeed or you’ll fail. Just learn from your mistakes and try again. It’s okay to fail, but at the end of the day Eventually you’ll have to make a choice. We all have to take a stand at some point in our lives, if we don’t want the Universe to leave us behind.
Except that would be a lie. It would have to say something like "The block might still be growing, there is a possibility you could lay the story, maybe". Not very inspirational or sciency. Besides, the whole idea of democratizing time makes no sense, because it's still measuring it from the frame of a human like consciousness, if we include other things then time is just movement. If something moves slower then time moves slower, and if something moves faster than time moves faster. And at the extremes of both time ceases to exist, they are essentially outside of time at opposite ends of the spectrum, which suggests we're dealing with something circular that loops back on itself. And if we take all that into account then the block of ice is more likely, because the growing block is intrinsically tied to the flawed, subjective, and not scientifically understood, idea of what humans consider consciousness.
@@alirezaomrani7650What if it wasn’t a growing block yet a frozen cube already set in your way of you getting that poster and getting motivation to do something.
Yes! Also I wonder if in the distant future conscious beings will be able to "mine" the block we are creating...and resurrect us long after we are dead. If the block exists, shouldn't it be accessible given enough time and technological advancement? I find this idea super inspirational
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.
It's the same as how if you ask a computer to determine which of two options are better it will always arrive at the same conclusion if you give it the same starting data. The calculations the computer went through to arrive at this conclusion aren't worthless just because it always arrives at the same one, they were still necessary and useful. If you view free will as more similar to this situation, basically an evolutionary adaptation that allowed us to handle difficult and novel situations by being able to think freely and abstractly, then it still clearly exists. And like there's no reason to treat free will as somehow special and different from all our other evolutionary adaptations since we aren't in any way seperate from the rest of life on this planet.
One more thing to add is that this is less time travel, and more just going to the future faster and irreversibly. You're just seeing the future world faster, and finding out what happens later. You didn't go to the future, your now just progressed sooner. Your friend's decision isn't eternally locked in stone when you go forwards in time, it's just you remeet them again years later to find out what choices they made.
@@hedgehog3180 You're correct about algorithms in a computer generating consistent results. However, my choices are ad hoc in comparison. Grab the can of Coke or the can of root beer from the fridge? My choice, on a whim. Unpredictable.
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.
Well there's what Einstein called 'spooky action at a distance' (quantum entanglement), so _theoretically_ it might be possible despite breaking causality. But I'm not smart enough to understand it properly, so please don't take my word for it.
In the sense of communication, sure. But what it does is more clearly illustrate something that we do know to be true, that your time frame is determined by motion through spacetime. And this we have observed through our GPS satellites gaining about 38.6 microseconds every day compared to clocks on the ground, due to time dilation. Though I personally don't think faster than light communication or time, travel necessarily needs to break causality, in the same way one could draw a flipbook involving a time traveling character. Essentially, the character would need to do something unrelated to the events on the previous panels, say they do something different in the background unnoticed to the foreground characters, thus not influencing them. (Unused information) Or do something that fulfills the events of previous panels. (Information that was there from the beginning anyway) In both cases there is no violation of causality.
Came here to say this. While it illustrates how time changes as you move faster, it ignores that each of those six points in spacetime have completely different presents, and wouldn't be able to interact. Not even through spooky action at a distance (unless you really like pointless guessing games that cannot be used for communication).
Your videos are amazing, you are so amazing. Thank you for making my days!!! I love what you do, and if I could I'd fill my walls with your posters. You're the best, thank you!!!

During a psychedelic experience, this was explained to me. A little differently, but parts of this resonate deeply with what I was told about life. Are you ready? Your life is already set. Free will exists, but you need to see it more like an exit on a highway. Your life is the highway. The things you are meant to experience in life are fixed. That doesn’t mean you can’t take an exit during your journey. You can take an exit to look around, have some fun, see what’s there, and gain new experiences. But eventually, you will always return to your highway-your path. You can’t change this. This is what was explained to me, and I believe it. It was presented so clearly, with an emphasis on specific goals.
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...
They don't really predict your stream of consciousness, i'd say it's just a question that naturally arises when a human being thinks of the topic, it's more our reality that constrains your stream of consciousness than Kurzgesagt that predicts a specific branch.
You're just too naive and straightforward at the topic. There's more paradoxes arises. Just not so long ago, in 2023 scientists proved that photon can change its properties because of its future pathway. Its been called time interferance. The research is named "Time slit experiment"
I believe your block universe theory is partially accurate; however, instead of a frozen future, I propose that all possibilities coexist simultaneously. For example, if you consider the scenario of missing a bus, the possibilities include: 1) arriving late for the bus, 2) successfully boarding the bus, 3) taking a taxi, or 4) receiving a ride from a friend. Each of these possibilities exists concurrently, and your actions ultimately determine which future will be your now
Ahhh yes, the future is the past, the past is debatable and the present is in the future. This makes me sleep so much more comfortable. Thank you for this explainer Kurzgesagt
You know THERE has to be one Absolute Truth/ Objective Reality (100%) [regardless of what different scientists, ph.ds, doctors, philosophers, societies, religions, cultures, individuals, etcetera believe]. The rest could be categorised as either - 1.) Some Truth with some Falsehood mixed in it (no matter in what ratio/ percentage it is in) or 2.) Complete Falsehood/ Delusion (100% Wrong). Its something like this - [If Analogy is to be used our Body is like a Hardware of the Computer and our Soul is like a Software. Just as Computer's Hardware is Useless without a Software, similarly, a Body is also Useless /Lifeless without a Soul.] We go through 5 Phases in our Life :- 1. The Realm (outside of this material Universe) where we took an oath & chose to be granted free will and want to be get Tested (The Testimony of believing in Only One God by our soul), 2. In our mother's womb (9 months) - The soul is breathed into the body, which gets created from a single molecule through a unique DNA🧬 (An Instruction Manual/ A Program/ Code) fashioned/ programmed by Creator. And, as the soul enters a body that's from where our consciousness and conscience comes (it happens with a lightning speed i.e. in a fraction of a second which Scientists/ Doctors couldn't able to capture it), 3. On Earth 🌎 (On an average of about 60-70 years) [Commencement of Test with the Development of Conscience], 4. In the Grave (The time frame from our death till the Day of Judgment/ Resurrection) & 5. In Paradise or Hell (Eternal Life). All are Temporary except after the Resurrection. So, the consciousness in brain 🧠 gets activated when soul enters the body & through soul the conscience (sense of right and wrong) of heart gets activated (including feelings like joy, peace, pain, anger, etc.).
They just don't want to be responsible for your "intentional premature exit from life", brought on by your realization that you are, for all intents and purposes less than a speck of dust. So they tell you it will be okay. Even though that changes nothing.
@@danielduncan6806 "Even though that changes nothing." I always find it a bit funny that people struggle with their irrelevance in the face of the universe. Yes, there are 10,000 stars for every grain of sand on Earth. How does this change anything for you? it is and will be as okay as it ever was. i shouldn't have to tell you to get used to it because you are used to it.
I had an experience on Salvia when I was younger where I could see the past present and future like a kaleidoscope where everywhere I had been were like photos of an old-school skate magazine. Everywhere in the future was the same and no matter what I did I couldn't stop myself from clipping into those future clips. I believe everything has happened.
These animations are so frickin adorable and hilarious. Holds your attention through the whole thing. What's being used to make them? Obviously requires a skilled artist and humorist as well...
If you are asking about the software used to animate, I would assume it's Adobe Animate. You can create simple animations pretty "easily" (you obviously need skilled professional artists of course). It's really good for this kind of stylized lineless corporate appearance.
Kurzgesagt mentioned in the past that they use Adobe Illustrator to draw the art, then Adobe After Effects to animate them. Check out their video about how they make a video in 2600 hours.
I’m more upset that they didn’t explore the most likely outcome of quantum effects: that each of those bubbles of now mesh via the Many Worlds / Everett interpretation in the universe branches like a fractal with bubbles intersecting and diverging in a mind breaking tapestry of reality. Determinism breaks down here in a model where everything that can happen at any given moment does happen in branching realities so the concept of frozen or growing block becomes meaningless.
After watching enough Kurzgesagt videos, I've realized the best thing to do is to live life like a commoner without thinking too much about the universe or the space-time continuum. ❤
9:31 If the whole video didn't give me an existential crisis, this line definitely did: "Others think that time itself doesn't even exist, that the whole concept is an illusion of out human mind."
Im one of those that think that "time" dosen't exist, its like a metric system that human kind create to measure movement, the same way that "cm", its just a measurement to understand an object. The "aging" or "passage of time" in living beings is the decay of the cells and particles inside the body. For example: International atomic time is just the measurement of the cetium 133 atom transition (sorry, english isnt my first language).
@@tetsuyakenshiNope. Equating the metric to what it’s measuring is like equating numbers to numerals. Our measurement of time is just a useful model of time, not time itself. Even the idea of a measurement is more useful to us than what we’re actually doing; we’re not _measuring_ time, we’re _representing_ it. In the same way we use numerals to represent numbers.
@@hibernopithecus7500 Comparing measurement its an easy way to explain why some ppl dont think that time exist. Either way, you dont represent time itself, you represents a specific event, "one day" is only a representation of the earth's rotation, "one year" is the representation of the earth's translation, "1 second" are 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom. None of these are "time itself". So, can you tellme, what is "time itself"?
I think the significance of quantum phenomena and randomness is overstated here. There is a distinction between something being unPREDICTABLE and something being unDETERMINED. Quantum events or radioactive decay are unpredictable (at least with certainty), but that doesn’t mean that the future is nondeterministic. One is an epistemological issue and one is an ontological one. For clarity, the two sentences can both be true without contradiction: “I cannot know if X will happen” “X will happen”
This video feels so weird because I have had that theory as well, but I could never explain it, and now someone else is here explaining my thoughts just like they were and I was never able to put it into words. Thanks KGS!
"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.

really, I often try to explain similar ideas to people around me and many don't listen at all, because it's too kind of absurd. Well, I'm probably not the best person to explain, but nevertheless
The problem here is the analogy at [03:02] with the magical instand communication. There is no instand communication and there never will be. c is the speed limit of the universe and the speed limit of information propagation. 2 rockets flying away from you each at naer the speed of light and in 90° to each other. When you do this though experiment (or watch minute physics on this topic) and switch perspectiv of those rockets while they communicate with the third person and each other, time gets real. You can send a message and someone can pick it up later. But noone can get the message before you send it. Time is not an illusion. It is a fundamental feature of this universe. And either is time the reason why the universe is expanding, or the expanding universe creates time. But you cant have one without the other.
True! The fact that the speed of light is finite really seems to be the hallmark of the fact that things really are REAL, they are out there, never fully reducible to their relations with other things. Light speed mediates measurement - or rather, since measurement is not some kind of fancy subjectibe action, but just another kind of physcial relation (as Einstein clearly showed in his special relativity paper), light speed mediates all relations. No instantaneous relation is possible, that is, things are NOT reducible to their relations, or even their constituents, but at all levels, every object maintains a hidden autonomy and reality. This is the way Object Oriented Ontology would read it, at least, and I really do like that philosophy.
To be clear, quantum mechanics might imply randomness, but there are equally valid theories of quantum mechanics that are completely compatible with a deterministic spacetime.
@@pumpkin_pants3828 It's not actually that complicated. The problem is most people don't typically spend their time conceptualizing what it would mean to exist within more than 4 dimensions. And just so you know, our Universe does possess more than 4 dimensions. It definitely has 5. Probably has more... but the limitations of our equipment kind of makes proving the existence of those dimensions beyond mathematics and theory almost impossible.
@@parlor3115I don't think they mean something other than QM. I think they mean other interpretations of QM. As they said, "equally valid theories of Quantum Mechanics". A point of clarity, Quantum Mechanics isn't the name of the theory. It's what we call practicing physics at the Quantum level. There are several valid theories on how Quantum Mechanics work, like the Copenhagen interpretation, or Superdeterminism.
As soon as the video started I was like "this reminds me of that episode from Don't hug me I'm scared, but there's no way they'll make that reference, right?" Thankfully, I was wrong.
I wrote about this exact topic as a teenager ~ for some reason, I always had this thought that the past, present, and future all exist right now simultaneously. Great video!
Me too! I used to think about this almost every day when I was a teenager and right up into college. Then I got a job and my mind put all that aside for years. Now I’m retired and starting to think about the notion of time once again. When I was young I began to think of time as a sort mechanism that would help me to understand the story that was my life. We can reference the past through memories and the future by means of our imagination and to some degree through planning. The always fleeting present is where we attempt to tie it all together in order to make sense out of all that we learn and experience. It doesn’t make much sense when I write it out now, but I remember that it made great sense when I first started thinking about it all those years ago.
But you said “always had this thought “ and “I wrote about this topic “ which would concluded that it’s not happening anymore . Which would mean lol it’s not happening the same time as the present , and it’s definitely not happening the same time as tomorrow. Just deep thought 😂that went to deep thought
This is exactly what I've been thinking lately. I feel like the future definitely doesn't exist. Time is a feeling. Time isn't material. The moving of the Earth around the Sun is just a movement, and we call it a year, but it's not a specific amount of TIME. A year could pass and it could feel like a minute. THAT is time, that feeling. Our perception of things changing and the feelings that come up because of that. Everything that has ever happened and will ever happen exists, yet we have free will. That's something we as humans can't understand, or at least I can't. I feel like there are lots of things we know exist but can't understand, like death or nothingness. Maybe those could be spiritual, maybe a way of thinking about the idea of god? All these ideas I value so much and I feel like I can't continue doing things every day without knowing what to think about them. They're all-encompassing. Thank you so much for this video, it helped me see other people think about what I've been thinking too.
The argument of free-will vs destiny has always confused me, because it's always seemed obvious to me that both exist simultaneously. The universe is a chain reaction of events, therefore everything happens the way it does because of the preceding events that caused it. You can choose to do whatever you're capable of, but whatever you do decide to do is what you were always going to choose because of the events that caused you to make that decision. Isn't this obvious? What am I missing? I have the free will to decide if I wave my hand in the air right now, or wave my foot around instead. But whichever decision I make, I will have made for some miniscule reason (even a thought), and that reason exists because of the entire chain reaction of events since the start of the universe that have caused it to be. Things are the way they are precisely because of the events that caused them. This also means that the entire future would be predictable if only we had all of the information of the causes and effects of the chain reaction available to us.
@@mskmagic3877 > but whatever you do decide to do is what you were always going to choose because of the events You're missing the influence of the quantum world here. Without quantum uncertainty, the universe would be 100% deterministic. As of now, that seems to not be the case.
@@ildar5184 Thank you for this response. But I still don't understand. Are we saying that the 'random' fluctuations of energy at a point is space are unknowable to US, or that that they don't happen for any specific reason? I can accept that the future couldn't be completely predictable for us, but I can't see why the chain reaction of events doesn't have a naturally predetermined outcome?
It's not just a feeling. We still need to do quantum mechanics! That's kinda hard if time's just in our heads. Think instead in terms of different kinds of time: psychological (for our feeling of time flowing), cosmological (for the Big Bang & the expansion of the universe), thermodynamic (for irreversible ever increasing entropy), and the clock for calculating the quantum wave function. They all do their own stuff to keep the cosmos ticking! (PS sorry but we don't have free will, that definitely _is_ just in our heads; whenever you think you make a decision it's really the culmination of a very, very long chain of subtle causes, 99% of which you're unaware. Like how a snowflake floats to the ground looks kinda random, but it's actually 100% completely determined.)
@@mskmagic3877 it depends on the interpretation of quantum mechanics you prefer. The Copenhagen interpretation says that wave function collapse is totally random and you cannot say anything about the exact properties of a particle in superposition, they are fundamentally undetermined. Superdeterminism on the other hand claims that everything is correlated with everything else, the particle not just with the measurement device but with the environment, the experimental setup and even with how the scientist(s) "chose" to set up the experiment therefore everything about the quantum particle is 100% determined and by extension also about us. Everything we do and think is totally 100% determined. Everything is correlated with everything else all the way back to the Big Bang.

But it doesn't change that there was a thought process, a decision, even when the output is already known.
Determinism or quantum randomness = No free will.

I hear it so often and had yet to hear someone question it, even though it seems so obvious that just because your decisions are fixed does not make you unable to make decisions. You just will always decide in the same way that the same version of you in the exact same situation would always decide.

THIS COMMENT WILL BREAK THE UNIVERSE BECAUSE IT WAS NOT PREDETERMINED
This is actually one of the philosophical questions I find myself pondering at various points in my life. There has been a handful of events in my life, that I’m sure others will be able to relate to, where a seemingly random frustrating or inconvenient event has made me late to go somewhere, however when I finally leave I find out that there was a devastating car crash that happened roughly at the exact time I would’ve been in that location if I’d left on time.
One that will always standout to me was when it felt like the “universe” was trying to stop me from leaving my home or possibly delaying me so time would line up for a crash, i.e. back to back inconveniences - my jacket got stuck in the door as I was leaving, then my key lanyard got caught on the door handle, and then my seatbelt got twisted and i had to fix it before i could leave). Once I finally left slightly later than I usually did, a car ended up backing into my drivers side door in a parking lot and that was my very first accident ever.
Looking back at things like this, to me, some moments in life certainly FEEL like the future has already been written and that events are going to happen on a schedule. Of course it could also be random and things just happen out of nowhere, but the times that life seemingly did its best to either delay me from getting in a car crash or caused me to leave at a time where the car crash actually happened stand out in my mind. My mom always describes it as a guardian angel when something delays you and to be aware of what’s going on more than usual as it could be trying to warn you about something about to happen, maybe time works the same way or is the guardian of our lives.
Just something I find really interesting to think about, I hope others can relate ❤

AsSalam Alaikum, peace and blessings of God be upon you and all brothers and sisters, children of our father Adam (as) and our mother Eve (as).
Dear brothers and sisters, usury (interest,loans,debts,inflation) has destroyed mankind. Kindly read these verses. God bless you.
---
Those who consume interest cannot stand [on the Day of Resurrection] except as one stands who is being beaten by Satan into insanity. That is because they say, "Trade is [just] like interest." But God has permitted trade and has forbidden interest. So whoever has received an admonition from his Lord and desists may have what is past, and his affair rests with God . But whoever returns to [dealing in interest or usury] - those are the companions of the Fire; they will abide eternally therein.
God destroys interest and gives increase for charities. And God does not like every sinning disbeliever.
Indeed, those who believe and do righteous deeds and establish prayer and give zakah will have their reward with their Lord, and there will be no fear concerning them, nor will they grieve.
O you who have believed, fear God and give up what remains [due to you] of interest, if you should be believers.

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
I think the universe prevents paradoxes.
Time could very well exist in these blocks, but when quantum mechanics comes into play, prior to the collapse of the wavefunction by an observation, the universe splits into the many worlds.
Perhaps t=0 was a single page, but for every plank-time after t=0 there would be an exceptionally large number of pages to represent each of the possible universes.
To break out of science and into my personal philosophical and spiritual beliefs - there is an untestable but fundamental analog of the fundamental quantum fields, this analog upholds consciousness-exclusive information like qualia for example.
I think the overall consciousness-field is literally in-and-of-itself conscious and capable of universal scale choices. I think that consciousness-field (which I consider as deity-like) is the universal child - but he's not drawing the pages, he's picking which pages go into the book (or books if time travel were to become possible).
The consciousness-field exists across time from the big bang to "Prime-Time," which would be defined as the time in which no conscious observer has yet born witness to collapse the wavefunctions.

Yea. Causality "spreads", at the speed of light... Which begs the question... in a sci-fi setting, could reality actually be rewritten? If a "causality wave" moves at the speed of light, would an "anti-causality wave" be able to cancel it impacting with the first, canceling the event retroactively?
Maybe not where the event already happened. What about canceling its spread... ?
What about the reversal of causality?
Can highly recommend Wolfram Physics - they have a whole theory where the universe is made out of causal events and nothing else
I was surprised this wasn’t brought up
@@sethheristal9561 Yes. Instead of thinking in terms of time and the speed of light. Think of reality in terms of MATTER and CAUSALITY - like dominos interacting with each other. Light moves at the speed of causality. And obviously when you move at the speed of light, YOU are moving at the speed of causality. But, you are moving at the speed of causality right now. Everything does. Your "particles" are currently whirring in orbits at the speed of causality. If you get in a spaceship and approach the speed of light, your particles move through the fabric of space, your causality is iterating through the fabric of space, slowing down the orbits of your particles because the speed of causality is constant, therefore it must be distributed between orbital and lateral motion. So, your orbital cells slow, and your thinking slows, but you are flying faster through space. So, stop thinking of it in terms of a clock. Think of it in terms of matter. Time is a tenuous concept that humans made up. A clock is just a spring under tension or an oscillating block of quartz anyway. Scientists have tried to track time accurately using cesium and found that the clocks diverge just by raising it off the floor. So how can you ever expect to track now? The concept of time understood by the general population is very primitive. We might as well believe we can "measure time" using ocean waves.
1:50 Finally, kirby is educational!!!
It's about time you got around to this topic. I've been waiting for it all my life.
now?
It really is about time, yes.
Perhaps it was already made, but you're only now experiencing it. If this was true, then you already have experienced it, just not relative to now, until now. So I ask, did you even really wait at all?
And according to this video, you will continue to wait ... forever.
Which life?
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.
thanks sir, if your young version's hypothesis was true, I knew how I can stretch my time literally. 48 hours a day? How beautiful!
Well I’ll be damned, I had similar kinds of thoughts like that myself from time to time. Still do
Strange thing is I even saw a brief 1 second glimpse of my own future once too. Didn’t realise until years after I dreamed it but it was exactly just as I had seen it. I haven’t had any since but perhaps that will not always be the case.
Makes you wonder doesn’t it? Is the future set in stone and strange fluctuations in the fabric of spacetime allow some premonitions, was it a bubble in the fluid ‘present’ allowing a brief glimpse into a possible future?
Are dreams even fabrications of the mind, or are they windows into viewing possible moments in alternate realities and parallel universes. Who knows
Strangely enough yes i had this thought that time moves differently under certain conditions. Are we all in sync or do we all have a static amount of time that gets spent at different rates? Do too much of one type of thing using up time faster and reach the end of life sooner etc.
The way we experience time has a lot to do with our mental state. For sure time does not pass equally for every being in the universe. I don't know how old you are, but 5 years in our childhood seems to take a lot longer than 5 years when you are an adult for example.
I started feeling like that when I was 7
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
BRO!! I WAS JUST THINKING THAT!!! (You read my mind)
Great minds think alike! Yeah! I would totally buy a poster like that!
For me the ideal slogan would be:
The Block grows, with or without you, but only you get to decide how.
Stack your bricks, or someone else will stack theirs. 🧱
I don’t know, I think the Universe favors those who make the first choice, though I still strongly believe you have to think things through first, you can’t just keep worrying about the end result forever, either you’ll succeed or you’ll fail. Just learn from your mistakes and try again. It’s okay to fail, but at the end of the day Eventually you’ll have to make a choice.
We all have to take a stand at some point in our lives, if we don’t want the Universe to leave us behind.
Except that would be a lie. It would have to say something like "The block might still be growing, there is a possibility you could lay the story, maybe". Not very inspirational or sciency. Besides, the whole idea of democratizing time makes no sense, because it's still measuring it from the frame of a human like consciousness, if we include other things then time is just movement. If something moves slower then time moves slower, and if something moves faster than time moves faster. And at the extremes of both time ceases to exist, they are essentially outside of time at opposite ends of the spectrum, which suggests we're dealing with something circular that loops back on itself. And if we take all that into account then the block of ice is more likely, because the growing block is intrinsically tied to the flawed, subjective, and not scientifically understood, idea of what humans consider consciousness.
@@alirezaomrani7650What if it wasn’t a growing block yet a frozen cube already set in your way of you getting that poster and getting motivation to do something.
Yes! Also I wonder if in the distant future conscious beings will be able to "mine" the block we are creating...and resurrect us long after we are dead. If the block exists, shouldn't it be accessible given enough time and technological advancement? I find this idea super inspirational
What was the point of this comment? Just to daydream about buying a cheesy product?

Yay, now I can question my reality and not know for certain whether I really exist. Thanks Kurzgesagt! 🎉
Why, you couldn't do that before watching the video?
you'll get over it eventually
Existential crisis, achieved.
But you do know though, you don't need to understand it, life is nothing but a inexplicable miracle, yet you live every day, why not believe in it?
yes you exist and are alive so go out and live instead of pondering nonsense such as this because its bad for your physcological and mental health!
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.
It's the same as how if you ask a computer to determine which of two options are better it will always arrive at the same conclusion if you give it the same starting data. The calculations the computer went through to arrive at this conclusion aren't worthless just because it always arrives at the same one, they were still necessary and useful. If you view free will as more similar to this situation, basically an evolutionary adaptation that allowed us to handle difficult and novel situations by being able to think freely and abstractly, then it still clearly exists. And like there's no reason to treat free will as somehow special and different from all our other evolutionary adaptations since we aren't in any way seperate from the rest of life on this planet.
@@hedgehog3180 Exactly!
Well said
One more thing to add is that this is less time travel, and more just going to the future faster and irreversibly. You're just seeing the future world faster, and finding out what happens later. You didn't go to the future, your now just progressed sooner. Your friend's decision isn't eternally locked in stone when you go forwards in time, it's just you remeet them again years later to find out what choices they made.
@@hedgehog3180 You're correct about algorithms in a computer generating consistent results. However, my choices are ad hoc in comparison. Grab the can of Coke or the can of root beer from the fridge? My choice, on a whim. Unpredictable.
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.
Yeah, I don't see how that thing implies there is any problem. Such communication is impossible for a reason.
Well there's what Einstein called 'spooky action at a distance' (quantum entanglement), so _theoretically_ it might be possible despite breaking causality. But I'm not smart enough to understand it properly, so please don't take my word for it.
Time travel, or also maybe knowing the exact position and momentum of a quantum object. Sort of breaks the rules.
In the sense of communication, sure.
But what it does is more clearly illustrate something that we do know to be true, that your time frame is determined by motion through spacetime.
And this we have observed through our GPS satellites gaining about 38.6 microseconds every day compared to clocks on the ground, due to time dilation.
Though I personally don't think faster than light communication or time, travel necessarily needs to break causality, in the same way one could draw a flipbook involving a time traveling character.
Essentially, the character would need to do something unrelated to the events on the previous panels, say they do something different in the background unnoticed to the foreground characters, thus not influencing them. (Unused information)
Or do something that fulfills the events of previous panels. (Information that was there from the beginning anyway)
In both cases there is no violation of causality.
Came here to say this. While it illustrates how time changes as you move faster, it ignores that each of those six points in spacetime have completely different presents, and wouldn't be able to interact.
Not even through spooky action at a distance (unless you really like pointless guessing games that cannot be used for communication).

Dont hug me im scared 😱
During a psychedelic experience, this was explained to me. A little differently, but parts of this resonate deeply with what I was told about life. Are you ready?
Your life is already set. Free will exists, but you need to see it more like an exit on a highway. Your life is the highway. The things you are meant to experience in life are fixed. That doesn’t mean you can’t take an exit during your journey. You can take an exit to look around, have some fun, see what’s there, and gain new experiences. But eventually, you will always return to your highway-your path. You can’t change this.
This is what was explained to me, and I believe it. It was presented so clearly, with an emphasis on specific goals.

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...
They don't really predict your stream of consciousness, i'd say it's just a question that naturally arises when a human being thinks of the topic, it's more our reality that constrains your stream of consciousness than Kurzgesagt that predicts a specific branch.
You're just too naive and straightforward at the topic. There's more paradoxes arises. Just not so long ago, in 2023 scientists proved that photon can change its properties because of its future pathway. Its been called time interferance. The research is named "Time slit experiment"
@@WiRaRI tried to read a paper on particle time once...once.😢
I believe your block universe theory is partially accurate; however, instead of a frozen future, I propose that all possibilities coexist simultaneously. For example, if you consider the scenario of missing a bus, the possibilities include: 1) arriving late for the bus, 2) successfully boarding the bus, 3) taking a taxi, or 4) receiving a ride from a friend. Each of these possibilities exists concurrently, and your actions ultimately determine which future will be your now
Thats a goid theory
It appears right. There are every possibility, and you choice.

You know THERE has to be one Absolute Truth/ Objective Reality (100%)
[regardless of what different scientists, ph.ds, doctors, philosophers, societies, religions, cultures, individuals, etcetera believe].
The rest could be categorised as either -
1.) Some Truth with some Falsehood mixed in it (no matter in what ratio/ percentage it is in) or
2.) Complete Falsehood/ Delusion (100% Wrong).
Its something like this -
[If Analogy is to be used our Body is like a Hardware of the Computer and our Soul is like a Software. Just as Computer's Hardware is Useless without a Software, similarly, a Body is also Useless /Lifeless without a Soul.]
We go through 5 Phases in our Life :-
1. The Realm (outside of this material Universe) where we took an oath & chose to be granted free will and want to be get Tested (The Testimony of believing in Only One God by our soul),
2. In our mother's womb (9 months) - The soul is breathed into the body, which gets created from a single molecule through a unique DNA🧬 (An Instruction Manual/ A Program/ Code) fashioned/ programmed by Creator. And, as the soul enters a body that's from where our consciousness and conscience comes (it happens with a lightning speed i.e. in a fraction of a second which Scientists/ Doctors couldn't able to capture it),
3. On Earth 🌎 (On an average of about 60-70 years)
[Commencement of Test with the Development of Conscience],
4. In the Grave (The time frame from our death till the Day of Judgment/ Resurrection) &
5. In Paradise or Hell (Eternal Life).
All are Temporary except after the Resurrection. So, the consciousness in brain 🧠 gets activated when soul enters the body & through soul the conscience (sense of right and wrong) of heart gets activated (including feelings like joy, peace, pain, anger, etc.).

If you are asking about the software used to animate, I would assume it's Adobe Animate. You can create simple animations pretty "easily" (you obviously need skilled professional artists of course). It's really good for this kind of stylized lineless corporate appearance.

“Ok. This is a lot... Imagine three spaceships 1 million light years away... “
I’m more upset that they didn’t explore the most likely outcome of quantum effects: that each of those bubbles of now mesh via the Many Worlds / Everett interpretation in the universe branches like a fractal with bubbles intersecting and diverging in a mind breaking tapestry of reality. Determinism breaks down here in a model where everything that can happen at any given moment does happen in branching realities so the concept of frozen or growing block becomes meaningless.

"Others think that time itself doesn't even exist, that the whole concept is an illusion of out human mind."
There Are Universes IN OUR Time CURVING OVER IT SELF into another one
And those One's space is time And Time=our space.
Im one of those that think that "time" dosen't exist, its like a metric system that human kind create to measure movement, the same way that "cm", its just a measurement to understand an object. The "aging" or "passage of time" in living beings is the decay of the cells and particles inside the body. For example: International atomic time is just the measurement of the cetium 133 atom transition (sorry, english isnt my first language).
@@tetsuyakenshiNope. Equating the metric to what it’s measuring is like equating numbers to numerals.
Our measurement of time is just a useful model of time, not time itself. Even the idea of a measurement is more useful to us than what we’re actually doing; we’re not _measuring_ time, we’re _representing_ it. In the same way we use numerals to represent numbers.
@@hibernopithecus7500 Comparing measurement its an easy way to explain why some ppl dont think that time exist. Either way, you dont represent time itself, you represents a specific event, "one day" is only a representation of the earth's rotation, "one year" is the representation of the earth's translation, "1 second" are 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom. None of these are "time itself". So, can you tellme, what is "time itself"?
I think the significance of quantum phenomena and randomness is overstated here. There is a distinction between something being unPREDICTABLE and something being unDETERMINED. Quantum events or radioactive decay are unpredictable (at least with certainty), but that doesn’t mean that the future is nondeterministic. One is an epistemological issue and one is an ontological one.
For clarity, the two sentences can both be true without contradiction:
“I cannot know if X will happen”
“X will happen”

The problem here is the analogy at [03:02] with the magical instand communication. There is no instand communication and there never will be. c is the speed limit of the universe and the speed limit of information propagation.
2 rockets flying away from you each at naer the speed of light and in 90° to each other. When you do this though experiment (or watch minute physics on this topic) and switch perspectiv of those rockets while they communicate with the third person and each other, time gets real.
You can send a message and someone can pick it up later. But noone can get the message before you send it.
Time is not an illusion. It is a fundamental feature of this universe. And either is time the reason why the universe is expanding, or the expanding universe creates time. But you cant have one without the other.
True! The fact that the speed of light is finite really seems to be the hallmark of the fact that things really are REAL, they are out there, never fully reducible to their relations with other things. Light speed mediates measurement - or rather, since measurement is not some kind of fancy subjectibe action, but just another kind of physcial relation (as Einstein clearly showed in his special relativity paper), light speed mediates all relations. No instantaneous relation is possible, that is, things are NOT reducible to their relations, or even their constituents, but at all levels, every object maintains a hidden autonomy and reality. This is the way Object Oriented Ontology would read it, at least, and I really do like that philosophy.

To be clear, quantum mechanics might imply randomness, but there are equally valid theories of quantum mechanics that are completely compatible with a deterministic spacetime.
Theories that contends with quantum mechanics? It's the most accurate one based on observation

@@pumpkin_pants3828 It's not actually that complicated. The problem is most people don't typically spend their time conceptualizing what it would mean to exist within more than 4 dimensions. And just so you know, our Universe does possess more than 4 dimensions. It definitely has 5. Probably has more... but the limitations of our equipment kind of makes proving the existence of those dimensions beyond mathematics and theory almost impossible.
@@parlor3115I don't think they mean something other than QM. I think they mean other interpretations of QM. As they said, "equally valid theories of Quantum Mechanics".
A point of clarity, Quantum Mechanics isn't the name of the theory. It's what we call practicing physics at the Quantum level. There are several valid theories on how Quantum Mechanics work, like the Copenhagen interpretation, or Superdeterminism.

I wrote about this exact topic as a teenager ~ for some reason, I always had this thought that the past, present, and future all exist right now simultaneously. Great video!
do u have any of ur writings still about this?
Me too! I used to think about this almost every day when I was a teenager and right up into college. Then I got a job and my mind put all that aside for years. Now I’m retired and starting to think about the notion of time once again. When I was young I began to think of time as a sort mechanism that would help me to understand the story that was my life. We can reference the past through memories and the future by means of our imagination and to some degree through planning. The always fleeting present is where we attempt to tie it all together in order to make sense out of all that we learn and experience. It doesn’t make much sense when I write it out now, but I remember that it made great sense when I first started thinking about it all those years ago.
I used do this too. I used to write about my versions of time, life, perception/reality, what happens inside a blackhole etc.
But you said “always had this thought “ and “I wrote about this topic “ which would concluded that it’s not happening anymore . Which would mean lol it’s not happening the same time as the present , and it’s definitely not happening the same time as tomorrow. Just deep thought 😂that went to deep thought

This is exactly what I've been thinking lately. I feel like the future definitely doesn't exist. Time is a feeling. Time isn't material. The moving of the Earth around the Sun is just a movement, and we call it a year, but it's not a specific amount of TIME. A year could pass and it could feel like a minute. THAT is time, that feeling. Our perception of things changing and the feelings that come up because of that.
Everything that has ever happened and will ever happen exists, yet we have free will. That's something we as humans can't understand, or at least I can't. I feel like there are lots of things we know exist but can't understand, like death or nothingness. Maybe those could be spiritual, maybe a way of thinking about the idea of god?
All these ideas I value so much and I feel like I can't continue doing things every day without knowing what to think about them. They're all-encompassing.
Thank you so much for this video, it helped me see other people think about what I've been thinking too.
The argument of free-will vs destiny has always confused me, because it's always seemed obvious to me that both exist simultaneously. The universe is a chain reaction of events, therefore everything happens the way it does because of the preceding events that caused it. You can choose to do whatever you're capable of, but whatever you do decide to do is what you were always going to choose because of the events that caused you to make that decision.
Isn't this obvious? What am I missing? I have the free will to decide if I wave my hand in the air right now, or wave my foot around instead. But whichever decision I make, I will have made for some miniscule reason (even a thought), and that reason exists because of the entire chain reaction of events since the start of the universe that have caused it to be. Things are the way they are precisely because of the events that caused them. This also means that the entire future would be predictable if only we had all of the information of the causes and effects of the chain reaction available to us.

You're missing the influence of the quantum world here. Without quantum uncertainty, the universe would be 100% deterministic. As of now, that seems to not be the case.
@@ildar5184 Thank you for this response. But I still don't understand. Are we saying that the 'random' fluctuations of energy at a point is space are unknowable to US, or that that they don't happen for any specific reason?
I can accept that the future couldn't be completely predictable for us, but I can't see why the chain reaction of events doesn't have a naturally predetermined outcome?
It's not just a feeling. We still need to do quantum mechanics! That's kinda hard if time's just in our heads. Think instead in terms of different kinds of time: psychological (for our feeling of time flowing), cosmological (for the Big Bang & the expansion of the universe), thermodynamic (for irreversible ever increasing entropy), and the clock for calculating the quantum wave function. They all do their own stuff to keep the cosmos ticking! (PS sorry but we don't have free will, that definitely _is_ just in our heads; whenever you think you make a decision it's really the culmination of a very, very long chain of subtle causes, 99% of which you're unaware. Like how a snowflake floats to the ground looks kinda random, but it's actually 100% completely determined.)
@@mskmagic3877 it depends on the interpretation of quantum mechanics you prefer. The Copenhagen interpretation says that wave function collapse is totally random and you cannot say anything about the exact properties of a particle in superposition, they are fundamentally undetermined. Superdeterminism on the other hand claims that everything is correlated with everything else, the particle not just with the measurement device but with the environment, the experimental setup and even with how the scientist(s) "chose" to set up the experiment therefore everything about the quantum particle is 100% determined and by extension also about us. Everything we do and think is totally 100% determined. Everything is correlated with everything else all the way back to the Big Bang.
Bro. You guys never fail to make awesome stuff
I watched it while waiting for the bus, the video asked if I was going to miss the bus 1 minute before it was supposed to arrive
CRAZYYYYYYY
Loved the “Don’t Hug Me I’m Scared Reference” ❤
Right!? I can’t believe they did that! 😮
I've seen this show but i can't relate which one, can you please enlighten me?
Came here to comment that
my dad is a computer
gave me a good laugh
This felt like the longest kurzgesagt video ive ever watched- never had so hard a time wrapping my head around it😭
Yeah I felt like I've been watching for a quite while, but when I saw the video timeline - turns out I'm still halfway 😅
It’s just the illusion of time
They need to play these videos in school if they did when I was in school I would have actually wanted to learn science
