  1. Kurzgesagt – In a Nutshell

    In the video we introduced Heisenberg’s uncertainty principle in terms of the effects of a measurement (what is sometimes called the observer effect). The two concepts are not exactly the same, but the observer effect provides an intuitive physical interpretation of the uncertainty principle—in fact Heisenberg himself used it as a physical justification of his principle. A more precise way to introduce Heisenberg’s principle is to see that very small objects, such as elementary particles, behave like waves: a famous experiment in quantum mechanics shows that electrons going past an obstacle “diffract”, i.e. they go around the obstacle. This is similar to how sound waves behave: if you sit in theater behind a column, you can still hear the music. The uncertainty principle is then a mathematical consequence of this wave description, or in more mathematical terms of the fact that “quantum observable do not commute”. In this sense it is not a principle in itself, but a consequence of the axioms of quantum mechanics; yet, given its historical importance in the development of quantum mechanics and the fact that it is a basic feature of quantum mechanical effects, physicists think of it as a founding principle of quantum physics. It is indeed correct that, while the observer effect gives an intuitive way to justify Heisenberg’s principle, nowadays physicists distinguish between the two, and they have been working hard to better understand their subtle differences.

      This is where dissension hits the ranks — only when we measure is its position ‘known’. Not blaming U — QM uses your statement.. But the mechanics of this, while taken as a given by QM, are what make QM not a universally accepted theory.

    So what do science say

  4. Karan and Team

    Actually this theory proofs time travel, when the compressed wave of light hits the quaks or sting whatever it displaces it.
    So already the object is vibrating, by the characteristics of matter i.e they are continuously moving .
    And the force of light will displaces the quaks or sting etc,
    And it will go to future.
    Since a particle moves to future when it moves faster, equal or a little less. By the theory of relativity by ienstien and theory of hawkins

    Shut your mouth, British pseudo intellectual pointdexter!

  11. StopFear

    How is “seeing something” is interacting with it? It’s a one way “interaction” so there is no real interaction when you only receive light in your eyes. You aren’t sending some rays from your eyes back at it. That’s why when something only goes one way it is not “communication”.

    I thought String Theory meant that every string is made up of even more strings.
    Because it’s a knot, made of knots….
    That’s what I thought it meant.

  52. Tyler Brown

  53. Barry Hough

    I can only believe in three dimensions. Not even time is a separate “dimension” – that proposal is just a theoretical physicist “waving his hands in the air”, trying to get grant money by nefarious, lying means.

    1. Locke

      You can believe anything you want to, but that doesn’t mean you’re right. Reality exists independent of your mind.

      Unless, you’re solipsistic, of course.

  54. Barry Hough

    The “vibrations” of string theory could be akin to light being an electromagnetic wave (or vibration of luminiferous aether).

  55. Barry Hough

    Gravity is not a special force, but rather it is electromagnetic force on the cosmic size level. We are like dust grains stuck by static cling to the Earth.

  56. Barry Hough

    I believe that fundamental errors in theoretical physics have led to absurd physics with no experimental basis. I am a Maxwellian – I believe in luminiferous aether in which electromagnetic waves travel. Of course being a Maxwellian, you have to reject not only Stephen Hawking, but also Albert Einstein’s proposal of the photon. I believe photons do not exist. Photons were proposed during “particle mania” when theoretical physicists thought that everything could be broken down to particles. This was an over-arching theoretical approach that was just not supported by experimental observation.

Is there a video where this is actually explained how physicist use these equations to study the universe. Or where would I go besides watching high school then University Physics videos online to learn something like this as a Layman

    Why we continue to struggle with this endless quest while is it all allready solved? Study the Abhidhamma: matrix of the entire existance (the elementary particles are not the ultimate undivisible unit) . The dhamma, the teachings of the Buddha… Please Science and mainstream Scientifics, WAKE UP!!! Help to free the world with the wisdom of the enlightened one.

  77. Faizan Ali

    This means there are literally unlimited possible versions of the universe. Also, who knows if these are the so-called “elementary particles”? It might be that we might not have the means of studying them good enough to realize there might be something that made these elementary particles.

    It’s entirely possible that the universe is as infinitely small, as it is (supposedly) big. We won’t thing until we find out about that specific thing.

    Who says the ‘fundamental particles’ cannot be further divided into small things. Small things that exist but are as tiny compared to their spheres of influence as stars are compared to the universe.

    1. Chaf Cancel

      Well, one of the Sci-Fi theory about elemantary particles is that it’s so complex that it may handle an entire universe within it. None of that was proved scientifically, it’s pure SF. So it’s another “story”.
      But it’s still better for us to consider the particles as points, rather than something that “can be divided even more”. It helps the math around the domain.

  100. Dwi Rimawanty

    “Mathematical fiction” the story of a point particle.. Is this what we call a mixture of fiction and reality? How can mathematician or physicist be of certain in a theory which comes from a fiction?

  101. Josh Byrne

    “2 + 2 does not equal 4, never has never will. That’s a simple fact.” “So what is the nature of the universe?” “Imagine a car speeding down a road on a loop, speed the clip infinitely and the car disappears.” “So what?” “Time. Time is the only true measurement. Time gives us existence.”

    Great video, but the part about the origin of string theory is a bit misleading. It was born largely because a few physicists realized that a few equations that we used to describe quantum phenomenon were describing something like a vibrating string.

  116. Bottas Heimfe

    i don’t think we’ll ever come up with a theory of everything. i mean, the universe is such a mind-boggling thing that i don’t think we CAN understand it in its entirety. there’s also the problem that the Universe is still relatively very young compared to the estimated time when total entropy occurs (which basically means when the universe as we know it dies), so things might change drastically as time goes on.

  130. Kara G

    One dimentional objects and two dimensional objects aren’t a thing. Sorry but it’s impossible. If an object was so small that it could not be cut in half “have a dimensional side that is zero”, then you could never build the larger objects they supposedly make up. You could stack them on top of each other forever and 0+0 will still give 0. Imo everything must be infinitely small and there is no point at which an object could not be split in two because it has no dimension. Every object has and is made of of other 3 dimensional objects with 3 dimensions that can each never be zero.

    Air did not come from trees.

    There are many different types of Air.

    And then there is Air, Himself.

    From whose fragments, air as we know it, came from.

    Big Powerful guy.

    Called Jehovah.

    Nature boy.

    Call him Him Higher Energy, if you want.

    Christians call Him Father in Heaven.

    Call Him God.

    The Fence around air.

    Trees have nothing to do with air.

    Allow me to say that.. for purposes of serious Divine Issues.

    I am not trying to destroy science, no.

    It took me 40 years of learning to be talking like this.

    Everything I have learnt, is to me, like a plus.

    Not a minus.

    Every learning helps.

    There is a Season.

    There is a Time.

    Thin Air tests like Jelly

    Ask your Government. What is Jabulani Mondhlani talking about?

    What is secret services about?

    The voice of recompense from the City: Isaiah 66:6

    Left Hand human car driving.

    Jabulani Mondhlani. The Right Hand Driver.

    Touchdown of The Creator.

    Touchdown of the God of Peace.

    What came first? Robots or humans?

    Having experienced Naturalization in the flesh centre of gravity physical manifestation of Jehovah on the life of God, Jabulani Mondhlani.

    Since 1977.

    I can safely say, I enjoy both the robot and flesh human.

    Power and Might Belongs to Our God.

    Jesus is Lord.

    I am God. There is none like me. Declaring the end. From the beginning.

    Back to Eden.

    What is the purpose of trees then?

    Very useful for spirits. That I can tell you.

    Those with higher Perception will tell you.

    The recycling of Air.. from Jelly. To Air as we know it after Eden. Was due to A Power called Air.

    The Source of Righteousness.

    It’s beautiful though. How science tries to teach Air.

    There are many different types of Air.

    And then, there is Air.

    The Fence Around Air, and the source of Air.

    There is someone there.


    I hear they are trying to use spraying and AI technologies, in the futile hope they can do something to Air.

    Jabulani Mondhlani. God.

    Kingdom of God.




    Great Britain.

    Ahead of time.

    And ahead of schedule.

    Jesus is Lord.

    The God of Life, Lightning and Thunder.

    The God of death as well.

    Who said there is or was a goddess of death?

    Where is she?

    Where they worshipping the Bride?

    The idiots.

    Jabulani Mondhlani. The Groom and The Bride.

    God of Heaven and Earth.

    The New Millennium Abrahamic Heaven and Earth Freedom and Peace Covenant.

    Jabulani Mondhlani. Jesus Christ.

    Welcome to The Rapture.

    Jabulani Mondhlani. Moses.

    Jabulani Mondhlani. Abraham.

    Jabulani Mondhlani. Father Abraham.

    Jabulani Mondhlani. Black Clay.

    Jabulani Mondhlani. White Clay.

    Jabulani Mondhlani. Iron.

    Jabulani Mondhlani. Iron next to Clay.

    Rule of Law World Government next to The Kingdom of God.

    Biblical Prophecy Fulfilment.

    I just happen to own everyone and everything.

    Jabulani Mondhlani. God.

Stop of time and strength of Mass of gravity is what a black hole is.! times stops becouse of our 5th dimension the vortex of a black hole is what our universe is expanding over and time slows to a stop there past the event horizon!!! to make other universes with out time, outside our universe cant Not be possible with out time to be present for the creation of other demotions on the other side of black hole! you cant exist out side of forward time besides stopping all time like a black hole dose the particles might be a reaction of some faster then light matter escaping faster then the event horizon of the gravitational pull of MC 2 and speeding up to our 4th dimension from the gravitational time distortion from a black hole!!!!!! even string theory’s leave out time from the start point of the big bang theory even in our universe is moving in time the 5th dimension is speeding our universe’s expansion time on time and mass !!!!!

    I’ve always heard people talk about string theory as basically a multiverse theory, where for every probability there exists a universe in which it occurs. Does string theory actually have anything to do with That?

    ② これらの意図はイギリスからの著書出版計画が急速に進み、内容が現代数学の初歩の欠陥を広く指摘し、現在の教科書、学術書の変更を求めているので、慎重に、慎重に対応したいということであった。上記サイトで述べられている要点をまず復習して置きたい。
    ゼロ除算 0 / 0 = 0 は 算術の創始者、ゼロの発見者 Brahmagupta (598 -668 ?) によって定義されていたにも関わらず、それは間違いであるとして1300年を超えて続いており、さらに、新たな説、論文が出版されている実におかしな状況にある。しかるに我々は ゼロ除算は既に当たり前であるとして、沢山の証拠を掲げて解説、説得を続けているが、理解は着実に進んでいるにも関わらず、理解は深くはなく、遅々として夜明け前のぼんやりしているような時代であると言える。数学者は、真実に忠実でなければならないのに、数学の研究では、論理には、感情や私情、予断、思い込みを入れてはならないのに、それが、数学の精神であるはずなのに かえって、数学者が予断と偏見、私情に囚われている状況が皮肉にも良く見える。 それは、ゼロ除算の理解が、素人の方の方が理解しやすい状況に現れている。 ― 数学は 絶対的に 厳格な論理でできているはずであるから、基礎が揺るぐはずがないとの信仰、信念を有しているためであろう。しかしながら、人間精神の開放と自由を求めて、非ユークリッド幾何学の出現から、人は大いに学ぶべきではないだろうか。 絶えず、人は何でも疑い、 我は存在しているか と 問うべきである。 ― 人間存在の意義は 真智への愛にある。
    ゼロ除算の歴史は、数学界の避けられない世界史上の汚点に成るばかりか、人類の愚かさの典型的な事実として、世界史上に記録されるだろう。この自覚によって、人類は大きく進化できるのではないだろうか。 ― 汝自らを知れ、というソクラテスの言葉は何を意味するだろうか。
    ゼロ除算の進展には 世界史がかかっており、数学界の、社会への対応をも 世界史は見ていると感じられる。 恥の上塗りは世に多いが、数学界がそのような汚点を繰り返さないように願っている。
    ゼロ除算は 不可能であるとの言明によって数学的には問題は永く封印されてしまった。 しかし、考えて見れば奇妙な事であった。アインシュタインや多くの物理学者が本質的な問題として考察を続けていたばかりか、ゼロ除算回避を意図して、計算機関係者や数学愛好者がともに真摯に追求してきたが、奇妙な議論を世界的に行っていた。 約20名くらいの海外の関係者と交流してきたが、少年期からあるいは何十年も空しい努力をしてきた者がいる。膨大な空しい努力に数学者の責任の感情が湧いて来る。そればかりか、数学全般の欠陥と我々の空間の認識がユークリッド以来おかしい様は、既に歴然であり、世の数学、世界観は天動説のように基本的な間違いが存在する。
    ゼロ除算は、発見されてまだ4年、今後大きな発展が行われて、現代初等数学の形相は相当に変化して、ゼロ除算発見は世界史上の画期的な事件として記録されるだろう。その歴史の大義を受けて、世界の数学界は 面目一新を図り、数学界の信頼を回復すべきである。

    We can’t really know the nature of reality this way. No matter what the physicist will come up with, these are nothing but abstract ideas. Sure they work in reality, they are proven and can be used to build stuff. But I mean really, some things may be completely beyond logical understanding. E.g. could we ever prove/disprove that the universe is not a simulation. What if it started a minute ago and all your memories and everyone else’s memories were injected. If so, could we even tell the difference? What even is the thing that you see right know, or the sound you hear? E.g. you are looking at a yellow wall, what the sensation of seeing a yellow color is? You hear a sound of a hands clap, what is the sound? What is the sensation itself of hearing the sound? What is consciousness?

    Nature never likes linear

  223. Christina Mooney

    We may never know everything there is, just as we complete the current searched for “theory of everything” we might find another piece that won’t fit the puzzle, such as discovering a new elementary type of particle smaller than an elementary particle that tells a story we could never of dreamed of.

    In theory, we are stepping closer to “everything”, walking towards the end of an infinitesimal long footpath of knowledge,

    Using pi (irrational number, not part of the Greek alphabet) as a model:
    I (Who only can recite pi as 3.14, I can’t remember any more) knows much less and as much as pi as someone who knows 100 significant figures of pi.

    Now you might be wondering:
    “If we are never going to reach the finish line, why are we still striding for it”, its for that feeling of accomplishment that keeps us going, to get a more accurate idea, and to further find a new story, more perspectives, another window we haven’t yet looked at the view, and I can tell you with each window the view gets more and more spectacular, and allows us to try new things.

    In short:

    be part of the team that runs that infinite marathon, find new windows never dreamed of, discover more horizons, what’s your theory of “everything”. Nothing’s the centre of THE universe. But you are the centre of the observable universe, and so am I and so is everyone else in the world, so so is no one but in the observable universe, of which is limited but the horizons are always growing,
    Will we sit and wait for more as the horizons expand, or will we dream and think of new horizons to test both what we know and what we won’t.

  233. Brianboy9494

    I’m sorry but there are two things fundamentally wrong in this video. First, the Heisenberg uncertainty principle is not the basis of all quantum theories. It is not even one of the axioms of either classical quantum physics, or quantum field theories. Second, in quantum field theories or even classical quantum physics, a particle os never just a point in space(time) – that is the classical mechanical point of view. In classical quantum physics a particle is described by a wavefunction and in quantum field theories a particle is the excitation of one of the fundamental quantum fields.

    Humans have been attempting to come up with “Grand Unified” Theories for decades now. I’m tempted to ask “what if there is no such thing?” but realise that I’m not really qualified. Dunning-Kruger here big time!

  261. TheWyrdSmythe

    I see your pinned correction, but you still gets points off for casually perpetuating the myth that conflates the HUP with the Observer Effect. Why go there at all, given it’s such a pervasive misunderstanding that even some physicists believe it?

  262. Gonçalo Santos Martins

    Thank you!

  263. Judgement Boy

    the problem that made it get discredited had nothing to do with flaws in string theory itself, and everything to do with the fact that no one was willing to accept that there were more than four dimensions, despite the piles of evidence supporting them, like garrett lisi’s E8 model that used an eight dimensional rotating grid that even predicted the ways quarks grouped into 3s, along with explaining the relationship between the forces and gravity, or the fact that even einsten fully accepted and endorsed the idea that the speed of light was calculated in the fifth dimension, along with several other hundreds of renowned physicists.

    the fifth dimension, by the way, is curled up at the planck length, making it unobservable, so that answers any questions you might have about “if there are other dimensions why can’t we see them?” that’s kind of the whole point of dimensions anyway, like, we’re in the fourth one (which is in fact spatial, not temporal – time is a direction and works both ways, see anti-matter), so how do you expect to directly observe the fifth? you can’t, but if you keep denying its existence you’ll never get that theory of everything you’re looking for. we can observe huge pieces of substantial evidence for these extra dimensions, and we’d probably find a lot more if we actually devoted experiments to looking for them.

    extra dimensions answer pretty much any question you can come up with about reality, and just because they seem unconventional or too “out there” to be considered in legitimacy, doesn’t mean they shouldn’t. the universe is a crazy and strange thing, what makes you think the explanation for it is going to be any simpler?
    totally recommend you check out rob bryanton’s “imagining the 10 dimensions” if you want more info on this stuff, it clears things up so well.

    This is so amazing, it’s clear now that as we learn more. More things will get more complicated, black holes, designers, life, atoms. Maybe atoms and black holes are opposites and are enemies. Atoms and particles split and black holes destroy. Everything is so perfect, so much in life.

    The ten dimensions of string theory exist simultaneously. The anthropic principle prohibits us from seeing past what we are biologically designed to see. We have SOME ability to perceive the fourth dimension (which is NOT time). Shifts in our perceptual faculties are needed to observe the processes of higher dimensions.

    1. Leptons are not necessarily elementary particles, they just have not shown to be definitely composite or non-composite yet.
    2. Observations can be made to ‘see’ effects without using light directly, such as with clever techniques such as laser interferometry or the proposed ‘dark matter radio.’
    3. Gravity just appears to act not as a ‘force’ because of the Principle of Equivalence, on which Einstein’s Theory of General Relativity is based. At higher energies this effect almost certainly disappears, general relativity no longer describes spacetime curvature, and gravity is just another force.

    You conflated point particles with string theory as equally useful endeavors despite string theory’s lack of predictive power. You should have just made the case for mathematicians rather than pretend string thoery compares in its utility to quantum field theory

    The contents are so interesting! But the cherry at the cake’s top is the animation. I have tons of fun watching those birds complement what’s being tol in an unusual way. Thank you, Kurzgesagt! Learning never has been so ludic! 🙂

    I get shivers of how much information is still to be known to mankind. But at the same time I almost have to puke of how complicated modern physics is. Anyone else feeling the same?

    If gravity doesn’t affect things that are smaller in size then how can it affect those small particles? i think the light bends around the particles so it becomes invisible.

  376. Lorra Crabtree

    Hi, my name is Lorra Crabtree. I currently live in Arkansas, USA. This year I will be 24 years old. I have something very interesting I want to share. I feel it is needed. I do not know where to really share this so here I am.
    So for a while now, most of my life, I’ve had these dreams where I travel to another world or universe. Basically I call it traveling the astral realms. I feel my soul and physical body separate to its smallest levels and when I get to this destination I come back together but in a different molecular level. I am able to fly and have contact with other higher conscious beings and also I talk and visit with people who look just like some people I know In this world, but maybe a few small differences. Same goes with some places I go when I travel. They look similar to the places in this world but a little different. My theory is I’m traveling into a parallel universe among other dimensions. I have grown very powerful in my abilities and awareness now since I have traveled among these places countless of times throughout my lifetime. Now this is no lie. I’m not making any of this up. I have another theory that I can fly in these places because of the anti gravity that is there and my energy that is there combining creating my ability to fly. Now I’m no genius or anything but I do feel I have a higher consciousness than most. So some of my wording my not be all the way correct but bare with me please like I said I’m no genius. I hope you or someone out there responds to my message. This is real.
    Oh I forgot to mention that the flying can vary in different ways. Sometimes it’s like hovering. Other times if the gravitational partials are fast enough in the area or where a portal is opened I can travel faster than light. When this happened I can feel my body pulling apart to its smallest molecular level and I feel an immense pull and see bright light all around. Then suddenly as fast as it began I feel my body rush back together. When the pulling and desperation is happening I can feel the dimensions or space around me pulling closer together letting me travel to where I want to go. Sometimes the feeling is so intense it’s like being reborn almost that’s the best way I can describe it.

    Maybe the other six dimensions are 1 dimension that only exists within black holes, and then an anti-time, anti-width, anti-length, anti-height, and an opposite of the black hole dimension.

  384. Tim

    I believe it was the God of Jacob that is being talked of in the first line of the book of John, “In the beginning there was the Word and the Word was God”. Ladies and gentlemen, if string theory is correct in the fact that subatomic particles really are vibrating, then I do believe we will have evidence of God.

    It’s cute humans still firmly believe this universe only holds 4 pleasurable dimensions. You may think we are experiencing 3rd dimensional space with a time coordinate, but we are actually only perceiving this vast greatness that way, our minds don’t allow us to see infer red nor ultra violet. Is it hard to believe our minds won’t let us precerive greater dimensions that we unknowingly interact with constantly?

    The video is great at explaining string theory but the claim that string theory might help to further science is strange to me. How can scientists use something that does not work to better understand the universe or even to develop the correct theory of everything? Please correct me if I’m wrong but it sounds to me like using “1+1=3 thus 2×2=6” – taking a wrong theory and developing it from there

    As science continues, and our measurements grow more precise, we will realize that the universe is a LOT more complicated than we think it is. We used to think that human cells were just blobs, simple building blocks — but we found that they are actually incredibly complex chemical machines. Now we treat particles like points in space — we will find that they are actually complex universes themselves.

    I think this video it not enough clear, espicially the part of String Theory. You should add more Information (with more style, joke or something). But I also think that you should give ducks more roles, although i already like the cuteness and comedy of them. Maybe the (really) main character is a good idea (The black duck rather is a “HUGE” minor role ). Eventually, I like your videos so much, including story, narrator, style of art and sense of humour. I hope you will further develop yourself and create precious and fun content in the future

  480. Brett Hummel

    Will there be a part two? I just don’t feel like string theory can be properly conveyed in one video. I felt like you covered the basics (quite literally) but didn’t go as in depth as needed to fully get people to grasp this concept. There’s so much more that can be said about it. Please make a part two!!!

    isn’t the fun in life not knowing what it is? why do we have to explore, create and destroy? we could sit on our wet dirtball floating in space, but we decided to explore elsewhere, that’s fun too, as it just opens more questions, leading deeper and deeper into the metaphorical void… for example, prove gravity, no matter how hard you try, nobody can prove this seemingly simple concept, yet we still try… quantum physics is just “hey, see all these unanswered questions? let’s fight fire with fire and answer a question with a question!” this comment is way too long, i should sleep now… why am i like this?!

  497. Bullboy5001

    the first part of this video is not correct. Although saying that we cannot see fundamental particles is correct, this is NOT THE HEISENBERG UNCERTAINTY PRINCIPLE. The Heisenberg uncertainty principle is saying (in a simple form) that the more you know something like mass (say you know this to an infinite accuracy) the less you will know the momentum of what you are measuring.Isaac Newton had a theory that if you had a snooker table and you could measure the momentum to an absolute extent then you could predict what happened in the past for the ball and the future. If you crashed 2 particles together and you knew the momentum infinitely accurate then you will not know where the particles are. This is really complicated to explain but I’m not saying that the video is bad I’m saying that it is scientifically incorrect. The principle you used is the OBSERVER EFFECT.

    p.s Keep up the AMAZING videos!!!!

      In startrek they made up a part in the transporter “the Heisenberg compensator” because people pointed out the Uncertainty principle made the idea of transporters theoretically unrealistic lol. Thought that tid bit was fun.

    4. VolTer

      I think the video was more flawed on the side of QFT, which was almost reduced to the size of casual quantum mechanics, and not going a bit more into how string theory was, and I expected more complaints about it than for the HUP – yes, a few corners were cut, but this is what happens when you condense a five-year program of advanced physics in a 7-minutes video for the general public. Otherwise, even with their skills, one would need 10 minutes to introduce QM, 10 minuted to introduce gravity, 10 minutes to introduce QFT/particle physics, and perhaps after that one could talk about string theory.

    Please, the pun in the Spanish subtitles about the “strings attached” shouldn’t be “viene con muchas cuerdas por detrás” (lit. “it comes with many strings underneath”), which isn’t funny nor doesn’t make sense.. it should be “deja muchos cabos sueltos”!

  512. Jakesto

    Even with the comment in the description I still think you have the Heisenburg uncertainty principle wrong. The observer effect is what you are talking about, but the uncertainty principle is completely different. It states that the more certain you are about one thing described by the wave function, the less certain you can be about the other. An example would be position and momentum. The more certain you are about one the less you can be about the other. The same applies to time and energy. The more mass something has, the less this applies as well, so it is only noticeable in tiny particles.

  520. Rotten pizza24

    Loved This video keep it up

  521. Jepoy Dizon

    Can you make a video on how they defined gravity and thanks

  522. E Nally

    You make learning fun I wish my science teacher Play this at science every day

  523. Souvik Dutta Chowdhury

    I want to know how economy work. They help us to make our society stable. But how do they work?

  524. Sebastian Buckingham-Bullock

    mind BLOWN

  525. sekite2

    I just came across your videos and i absoloutley love them! The Narration as well as the animations are just simply gorgous! Also im really interested in those topics… so, big thumb up! Also, a mans never hot! 🙂

  526. Andulas is

    Why would anyone dislike your videos

  527. Amritraj chaudhary

    Is uncertainity principle uncertain

  528. MrBanainai

    Psh, who believes in seeing?

  529. JiTiAr35

    Can you do a video about UFO?

  530. Mark Joseph Montealto

    String theory… Tardigrades…


  531. Chris William

    Am I the only one who feels more confused than enlightened after watching this video?

  532. wolf king

    2+2 is 4 [ ( in my mind ) -1 that’s 3 quick mafh ]

  533. D K

    Nope, still don’t understand it.

  534. magicstix0r

    A scientific theory that makes no testable predictions and still doesn’t unify relativity and quantum physics… Can it really be called “science” at this point or is it more just mathematical masturbation?

    1. Phoenix

      String theory *does* make testable predictions. It predicts strings. It predicts magnetic monopoles. It predicts subtle corrections to the standard model which is simply an approximation with respect to the more fundamental, more “correct” string theory. This is just like how classical mechanics is an approximation of the more fundamental quantum mechanics but the two make the same predictions at the everyday size scale (see correspondence principle).

      The problem is we are not yet technologically advanced enough to conduct experiments at the energy levels required to test for the subtle differences between string theory and the standard model. This certainly doesn’t mean string theory is false or correct, it means it’s still awaiting experimental trials.

  535. ChrisLovesNature

    “any evidence that we get could be simulated”

  536. Ethakaingeneral

    Sure, all electrons ARE fundamentally the same, but they come in two main varieties. Spin up and spin down. Fun fact: this is why there are only two electrons in each orbital. Because no two electrons, which are a type of fermion, can be in the same state.

  537. Mafu Mini

    wow now i am feeling so smart?

  538. Grace Smith

    Do when black holes collide pls I’m still very confused about the whole thing

  539. doct0rnic0

    I expected more depth. I know it’s short, but I don’t particularly feel like I know much about string theory after that, apart from its very basic principles. Add to that that a lot, there are a lot of assumptions that the viewer is already rather well informed about other terminologies and theories. You couldn’t do several several episodes on one single subject, could you, like the What I’ve Learned channel? That is really interesting…

  540. nightfire burn

    Why does the music remind me of gravity falls

  541. nightfire burn

    Can you do an episode specifically about troy?

  542. Speckles_Cheetah

    I love this Channel!
    And this Video Mindblowing! Wow and thank you for such quality content!

  543. shaan sundar

    Dear Kurzgesagt,


    thanking you

  544. Tony Alcantara

    Good vidoe

  545. Filip Risstic

    Man theese videos…

  546. nygge

    Looking forward for the Danish subtitles to arrive, can’t wait to show this to my students ?

  547. Jess Koch

    Hey, this video didn’t cause me any existential dread this time! Good job!

  548. Abrar Ahmad

    i wait for your video unabated. plz keep uploading good stuff

  549. tornadochaser786


  550. quy le

    sheldon cooper’s work lol

  551. JamesFrancesco

    The uncertainty principle is not the basis of anything. It’s a mathematical consequence

  552. Damien King-Acevedo

    2 + 2 is not 4 in a small enough ring; I’m being picky, but when you’re talking specifically about higher level maths, I think it’s disingenuous to act like you’re talking about nothing more complex than the natural numbers.

  553. Kevin Sigue

    my brain just exploded.

  554. Kevin Zhang

    Yes! Finally, a video by Kurzgesagt that talks about something interesting and fascinating!

  555. psprog

    Love the videos – such high quality, and easy to understand. My new favourite channel. The narration is great too (very English!) – though in this video he keeps saying “story” instead of “theory” 😉

  556. metaschimatismoús

    I’m taken away, once again kurzgesagt!

  557. Dead Account

    Your voice is the only reason I watch these vids ??

  558. Jac Val

    Can you do a video on black holes please?

  559. Dan The science man

    You would square the math ten times, and un-square it six times

  560. El rey

    Hope science finds a cure for feminism someday.

  561. kimberly sims

    Eeeeep eeeeeeep

  562. Patrick Mize

    That smooth ass intro

  563. Andrew Marceau

    I love your videos so much! Please make more!

  564. Nman3000

    I watched this video in class

  565. Robert Minsk

    this vid was made 9 days ago. it has exactly 9,435 comments. that’s assuming about 1,048 comments every day! see, Kurzgesagt, we can all be quantum physicists.

  566. Nishit Tomar

    Can u pls make a video on something with zero density

  567. Gaiden Castro

    Perhaps some frequencies of the universe could only interact with certain other objects of that frequency?

  568. Ankit Rathi

    The animation is really very great. The colorfulness and story in video makes video much interesting. Thanks for great quality videos 🙂

  569. faissialoo

    What makes us think there aren’t really 11 dimensions and we’re only capable of experiencing 4?

  570. Arnold Mwanza Kabuya

    I feel like Sheldon now

  571. Sanjana Singh

    ba-dum-tiss….After giving us the manga and anime series, Kurzgesagt is back with a new gaming series!!!

  572. Juzo Juzo

    Dieser Moment wenn die deutschen Qualitäts-Youtuber (kann man das so sagen) ihre Videos auf Englisch machen…

  573. TRANCE _

    Can you explain quantum mechanics??? Please

    1. TRANCE _

      Abdulaahi Adam ok I will see that

    2. Abdulaahi Adam

      TRANCE _ they did a quantum computer video i think that explained it.

  574. Soham Dange

    Great explanation dude! It gave या nice overview of particle physics.

    Also now I understood the uncertainty principle fundamentally!!

  575. suraj tiwari

    Do you really need patreon support even after millions of views in 1 day and *sponsorship* . *Stop fooling!* Concentrate on work, be passionate not *greedy!*

  576. A Study of Everything

    if anyone here is scientist or physicist….. then I want to tell you that I have discovered the basis of theory of everything by solving the gravity problem with graviton and I have also the mathematical structure of the same with some incredible formula….so, if anyone here who is in this field please contact with me….as I am very much afraid to publish my theory as there I’d a strong possibility that someone may steal my theory as I am not a scientist , but only a physics student till now and amateur astrophysicist….. so, please help anyone for the sake of mankind….and you can also subscribe to my channel to see more amazing videos about different scientific topics….thanks….I am waiting for anyone to help…..

  577. Joseph Engelhardt

    I love the simple language in this.

  578. WierdGamer

    What about the scientist who got closest to absolute zero? The atoms turn into something completely different. They turn into pure waves. They are called something-einstein condensates. But what are waves? Aren’t they just…. strings between matter and force itself? When light hits the condensate, it actually slows to the speed of a bicycle. Please help the channel see this. It might help with this discussion about string theory.

  579. miss misanthropist

    there’s so many sound effects i recognize

  580. AFC Marco

    The animation, as well as the narrator make this channel one of the best on YouTube. Absolutely love you guys.

    1. Lance Maronay

      reminds me of hitchhikers guide. in simple terms and same animation style. so well done.

  581. Drew z

    i don’t understand the down-votes? did they not explain something well that someone is disagreeing with? are the down-votes coming from the possible 11th dimension i read about?

  582. DontMockMySmock

    Tying the uncertainty principle to the observer effect is WAY WRONG dudes. In your comment pinned I see that you say “the two concepts are not exactly the same,” but that’s a huge misstatement. The two concepts are UNRELATED IDEAS. Even if Heisenberg “used it as a physical justification of his principle,” he was wrong. And the differences aren’t “subtle,” they’re entirely different ideas that have nothing to do with one another. One is a statement about waves, and the other is a statement about interactions between things whether they’re waves or not.

    1. DontMockMySmock

      You also never mentioned SUSY or how we get rid of those extra dimensions, but I guess I can’t blame you too much for cutting for time.

      I also didn’t like your rather optimistic take on string theory at the end, given that it has basically no use, can’t predict anything, relies upon another theory (SUSY) that is practically disproven, etc. It was an interesting idea worth exploring, once upon a time, but that ship sailed over twenty years ago and now we’re just beating a dead horse with millions of dollars of grant money for basically no reason. (I wish that researchers who are curious about quantum gravity would focus their attention on newer ideas that suck less, that’s all.) It definitely felt like you were downplaying the criticisms.

      All in all, a disappointing video from a channel which has never disappointed me before.

    2. DontMockMySmock

      You then proceed to describe the conflict between QFT and GR wrongly. And then you say that string theory was invented as a theory of quantum gravity, which it wasn’t – it was invented originally to do the job that QCD does now – explain the behavior of hadrons.

  583. Tayna Weher

    Surprisingly uninformative.

    1. Gary Buckley

      *Tayna Weher* ~ Leave some pussy for the rest of us!

    3. forever and ever

      Tayna Weher maybe you know too much that this video doesnot affect your knowledge.

  584. Super posh

    Opens a box of universe stuff…


  585. Super posh

    I love how the ad is in the same style as your actual videos

    How to explain wrongly quantum theory in a nutshell.

  589. Srikanta Dash

    hi your project is very good, animation is Awesome , please help me how i will make this type of video

  590. Omar Tarek

    Anyone else wants to play that Kurzgesagt video game? 🙁

  591. Jacobb Tonkss

    Oooooooooooooooh the references!!

  592. Northan

    I Found kurzgesagt in Royal Tyrell museum in canada 😛 (I think) :,D

  593. lopelipo

    I just feel boosted with knowledge when watching anyone of their videos ?

  594. Salman Ananda Chowdhury

    Instead of replacing zero dimensional particles of particle physics with one dimensional strings, wouldn’t it make more sense to replace those particles with four dimensional objects? clearly, the universe is at least four dimensional, so the elementary ‘particles’ should also be four dimensional, right? strangely I couldn’t find anything of this sort in Google, I’d guess few people have tried this approach because it sounds like a computational nightmare.

  595. Emily

    The reason I love Kurzgesagt is that its all so easy to understand. The images in the videos are detailed but not so much they make you lose focus and lose track, and its all explained in such a manner that anybody can understand it. Also, the person who speaks in the videos is an amazing speaker and his is the only voice that I don’t get bored of listening to after a few videos. I hope the team at Kurzgesagt keep up the amazing work!

  596. Mardick Celis

    I don’t know where to suggest the topic. So, I’m commenting it here. Can you create a video about the space time continuum; Can it be possible? Love the colors and how this is so informative. Thank you! More power to you. 🙂

  597. DoDsoníkova Videa CZ/SK

    Dobrej překlad Patriku 😀

    I really want my own bird avatar…!


  603. Yasin Kılıç

    Uhhhhhh too much science

    1. forever and ever

      Yasin Kılıç cuz its Kurzgesagt.

  604. Katze

    The only video/text that I have found that explains WHY a particle changes when you look at it.

  605. Upcycle Electronics

    I want to go to story school!!

  606. JJ

    sounds like string theory is more unknowns than knowns

  607. Matt Kessler

    What if we were to take an ordinary electromagnetic light wave and somehow squeeze it to make it smaller and pin point it on the gravitational field of the particle and concentrate that with light surrounding it to make it visible to the eye with a super telescope… jk I have no clue what I’m talking about.

  608. pushLife Co

    you guys are really awzme

  609. Mike Davies

    I think I solved String Theory… Is it f(n)=n°π?

  610. Robert Bourbon

    There are definitely over 10 dimensions.

  611. Marcus

    These videos are so damn relaxing I can’t be the only one who’s addicted. 10/10 for the sound and animation teams on this ???

  612. Tylorgng

    If your tripping and watching this u know what we have to do

    1. Darklink9110

      lol what’s that
