What is the true nature of the universe? To answer this question, humans come up with stories to describe the world. We test our stories and learn what to keep and what to throw away. But the more we learn, the more complicated and weird our stories become. Some of them so much so, that it’s really hard to know what they’re actually about. Like string theory. A famous, controversial and often misunderstood story, about the nature of everything. Why did we come up with it and is it correct? Or just an idea we should chuck out? To understand the true nature of reality, we looked at things up close and were amazed. Wonderous landscapes in the dust, zoos of bizarre creatures, complex protein robots. All of them made from structures of molecules made up of countless even smaller things: Atoms. We thought they were the final layer of reality, until we smashed them together really hard and discovered things that can’t be divided anymore: Elementary particles. But now, we had a problem: They are so small that we could no longer look at them. Think about it: what is seeing? To see something, we need light, an electromagnetic wave. This wave hits the surface of the thing and gets reflected back from it into your eye. The wave carries information from the object that your brain uses to create an image. So you can’t see something without somehow interacting with it. Seeing is touching, an active process, not a passive one. This is not a problem with most things. But particles are But particles are very, But particles are very, very, But particles are very, very, very small. So small that the electromagnetic waves we used to see are too big to touch them. Visible light just passes over them. We can try to solve this by creating electromagnetic waves with more and much smaller wavelengths. But more wavelengths, means more energy. So, when we touch a particle with a wave that has a lot of energy it alters it. By looking at a particle, we change it. So, we can’t measure elementary particles precisely. This fact is so important that it has a name: The Heisenberg uncertainty principle. The basis of all quantum physics. So, what does a particle look like then? What is its nature? We don’t know. If we look really hard, we can see a blurry sphere of influence, but not the particles themselves. We just know they exist. But if that’s the case, how can we do any science with them? We did what humans do and invented a new story: A mathematical fiction. The story of the point particle. We decided that we would pretend that a particle is a point in space. Any electron is a point with a certain electric charge and a certain mass. All indistinguishable from each other. This way physicists could define them and calculate all of their interactions. This is called Quantum Field Theory, and solved a lot of problems. All of the standard model of particle physics is built on it and it predicts lots of things very well. Some quantum properties of the electron for example have been tested and are accurate up to 0, 0,00 0,0000 0,000000 0,00000000 0,0000000000 0,000000000000 0,0000000000002 %. So, while particles are not really points, by treating them as if they were, we get a pretty good picture of the universe. Not only did this idea advance science, it also led to a lot of real-world technology we use everyday. But there’s a huge problem: Gravity. In quantum mechanics, all physical forces are carried by certain particles. But according to Einstein’s general relativity, gravity is not a force like the others in the universe. If the universe is a play, particles are the actors, but gravity is the stage. To put it simply, gravity is a theory of geometry. The geometry of space-time itself. Of distances, which we need to describe with absolute precision. But since there is no way to precisely measure things in the quantum world, our story of gravity doesn’t work with our story of quantum physics. When physicists tried to add gravity to the story by inventing a new particle, their mathematics broke down and this is a big problem. If we could marry gravity to quantum physics and the standard model, we would have the theory of everything. So, very smart people came up with a new story. They asked: What is more complex than a point? A line- A line or a string. String theory was born. What makes string theory so elegant, is that it describes many different elementary particles as different modes of vibration of the string. Just like a violin string vibrating differently can give you a lot of different notes, a string can give you different particles Most importantly, this includes gravity. String theory promised to unify all fundamental forces of the universe. This caused enormous excitement and hype. String theory quickly graduated to a possible theory of everything Unfortunately, string theory comes with a lot of strings attached. Much of the maths involving a consistent string theory does not work in our universe with its three spatial and one temporal dimensions. String theory requires ten dimensions to work out. So, string theorists did calculations in model universes. And then try to get rid of the six additional dimensions and describe our own universe But so far, nobody has succeeded and no prediction of string theory has been proven in an experiment So, string theory did not reveal the nature of our universe. One could argue that in this case string theory really isn’t useful at all. Science is all about experiments and predictions. If we can’t do those, why should we bother with strings? It really is all about how we use it. Physics is based on maths. Two plus two makes four. This is true no matter how you feel about it. And the maths in string theory does work out. That’s why string theory is still useful. Imagine that you want to build a cruise ship, but you only have blueprints for a small rowing boat. There are plenty of differences: the engine, the engine, the materials, the engine, the materials, the scale. But both things are fundamentally the same: Things that float. So, by studying the rowing boat blueprints, you might still learn something about how to build a cruise ship eventually. With string theory, we can try to answer some questions about quantum gravity that have been puzzling physicists for decades. Such as how black holes work or the information paradox. String theory may point us in the right direction. When used in this spirit, string theory becomes a precious tool for theoretical physicists and help them discover new aspects of the quantum world and some beautiful mathematics. So, maybe the story of string theory is not the theory of everything. But just like the story of the point particle, it may be an extremely useful story. We don’t yet know what the true nature of reality is but we’ll keep coming up with stories to try and find out. Until one day, Until one day, hopefully Until one day, hopefully, we do know.

    Actually, I was thinking about the elemental particles that we're not supposed to see.
    I'm not a scinentist or anything, but I wonder what would hapen if we could force these particles to generate their own light, like, by heating them or something

    As may be established empirically, matter is not essential so that existence may be made subject to it, and be dependent on it. Rather, matter subsists through a meaning, and that meaning is life, it is spirit.
    Also, as may be established through observation, matter is not the thing served so that everything may be ascribed to it. It is rather the servant; it renders service to the process of the perfection of a truth. And that truth is life. And the fundament of that truth is spirit.
    Also, as is self-evident, matter is not dominant so that recourse may be made to it or perfections sought from it. Rather, it is dominated; it looks to the decree of some fundament, it is in motion in the way that that decree dictates. And that fundament is life, it is spirit, it is consciousness.
    Also, as is necessary, matter is not the kernel, it is not the fundament, it is not a settled abode so that events and perfections may be affixed to it or constructed on it. Rather, it is a shell prepared to be split, rent, dissolved; it is a husk, it is froth, it is a form.
    Consider the following: a creature so minute it can only be seen with a microscope has such acute senses it can hear its friend's voice, and see its sustenance; it has extremely sensitive and sharp senses. This demonstrates that the effects of life increase and the light of the spirit intensifies in proportion to the reducing and refining of matter. It is as though the more matter is refined and the more we become distanced from our material existences, the closer we draw to the world of the spirit, the world of life, and the world of consciousness; and the more intensely the heat of the spirit and the light of life are manifested.
    Is it therefore at all possible that there should be this many distillations of life, consciousness, and spirit within this veil of materiality, and that the inner world which is beyond this veil should not be full of conscious beings and beings with spirits? Is it at all possible that the sources of these numberless distillations, flashes, and fruits of meaning, spirit, life and the truth apparent in this material existence in the Manifest World should be ascribed only to matter and the motion of matter, and be explained by it? God forbid! Absolutely not! These innumerable distillations and flashes demonstrate that this material and manifest world is but a lace veil strewn over the inner and spirit worlds.

    Fifth Principle:
    You will understand, too, that all of these transient objects have not been created for the sake of annihilation, in order to appear briefly and then vanish. The purpose for their creation is rather briefly to be assembled in existence and acquire the desired form, so that these may be noted, their images preserved, their meanings known, and their results recorded. This is so that, for example, everlasting spectacles might be wrought for the people of eternity, and that they might serve other purposes in the realm of eternity. You will understand that things have been created for eternity, not for annihilation; and as for apparent annihilation, it has the sense of a completion of duty and a release from service, for every transient thing advances to annihilation with one aspect, but remains eternally with numerous other aspects.
    Look, for example, at the flower, a word of God's power; for a short time it smiles and looks at us, and then hides behind the veil of annihilation. It departs just like a word leaving your mouth. But it does so entrusting thousands of its fellows to men's ears. It leaves behind meanings in men's minds as numerous as those minds. The flower, too, expressing its meaning and thus fulfilling its function, goes and departs. But it goes leaving its apparent form in the memory of everything that sees it, its inner essence in every seed. It is as if each memory and seed were a camera to record the adornment of the flower, or a means for its perpetuation. If such be the case with an object at the simplest level of life, it can be readily understood how closely tied to eternity is man, the highest form of life and the possessor of an eternal soul. Again, from the fact that the laws each resembling a spirit according to which large flowering and fruit bearing plants are formed and the representations of their forms are preserved and perpetuated in most regular fashion in tiny seeds throughout tempestuous changes – from this fact it can be easily understood how closely tied and related to eternity is the spirit of man, which possesses an extremely exalted and comprehensive nature, and which although clothed in a body, is a conscious and luminous law issuing from the divine command.
    Sixth Principle:
    You will also understand that man has not been left to graze at will, with a halter loosely tied around his neck; on the contrary, the forms of all his deeds are recorded and registered, and the results of all his acts are preserved for the day when he shall be called to account.

    Isnt the "observer effect" what is described as heisenbergs uncertainty here? I think I am correct in thinking that heisenbergs uncertainty is Not the principle by which the interaction of light with something alters its measurement; rather, it is the "trade off" in the accuracy of measuring two related observables due to QM effects (i.e. pos and momentum) ?

    im sorry, this video didn't really explain anything. with the pretentious "in a nutshell" profile name and "explained" in the title i was hoping for more. call me a troll or a hater but its hard to find string theory as a realistic viable solution with the math was beautiful and worked out. we can't see it or interact with it cause of the restrictions of physics, we can't disturb it due to the uncertainty principle and the current theories basis is that "we thought of it as a dot and so it was". as uncertain as quantum physicist are about the location and momentum of a subatomic particle are, you can at least do us enough justice not to pretend string theory can be explained in a nutshell.

    Shadow Spin String Theory. by Kenneth William Feemster.
    01/20/2016

    About The shadows caused by charged particle. The shadow behind the proton caused by electrons presents, must be very narrow and radiate out. Just like the shadow behind the electron must be a tight beam. A like a long narrow
    straight, like string,
    shadow radiating out.
    But electrons and proton have spin so these shadows, spiral around the whole system, bent by the spinning
    electro static fields. The shadow bend forward into the spin electrostatic charge and then at a certain distance, farther out, where the spin starts to be come a fraction of the speed of light the shadow change direction.
    Kind of like a flatten out spring. The way atoms hold onto each other by hooking on to the spiraling shadows.

    The hydrogen atom and neutron creation.
    When a electron comes near a hydrogen atom, the electron will move toward the proton, the proton will start to spinning faster. The electron will change coarse into the spinning electrostatic breeze, going into orbit. Because of a
    Doppler like effect of a negative electron moving head on into a spinning positive electostatic field.
    Electrostatic field can spin a up to superluminal speeds.

    The electron does not pick up much spin, but move laterally. It goes into orbit. The electron will pick up spin from the proton within a certain distance. On the steep part of the positive electrostatic, from the proton slope on a 1/f^2 mathematical curve. None or little on the flat part.
    When a electron move toward a proton, and by luck chance that it flies toward it on a perfect bulls eye, which very very rare. When the electron does get get very close to the proton they both spinning up to the speed of light, and
    greater. This is where the MC^2 energy is at. And a neutron is born.

    Electrons in the spin of a positive proton electrostatic field that are spinning at fraction of the speed of light, or greater, time will slow down in the spinning disc of the electrostatic field. Particals will get stuck in the thickest of honey. And will be dragged with proton where ever it goes. A electron will be frozen in orbit, and also spiraling shadow tail structure.
    A star ship moving at the speed of light, cutting through all of the ambient back ground positive spin, time will slow down. A spinning black hole dragging its space time with it.
    When a electron spins at at a fraction of the speed of light time speed up. Like the effect between entangled electrons.

    ok so with string theory lets say the multiverses theory was real and string theory says that maybe another universe is having the heat death theory and everything is closing in on each other creating too much gravity which creates worm holes to othe universes in what we call black holes and thats how black holes are able to suck anything and everything into them untill the other universe cant close in on itself anymore that starts expanding again which is the big bounce theory and no one will be able to prove this because no one will ever live long enough to know (am i crazy here )

    (The universe is held in balance with this number +0.007 for dark energy) As
    beautiful as it sounds String Theory is purely hypothetical like imagining
    that all women want to wear a thong or string theory. Sorry, butt I have to say
    this the theory is like a fairy tale and will make you go crazy
    thinking how I can get the string theory in all the cracks.

    There needs to be a String Theory 2. This video covers the concept of the theory, but not the content of it.

    I'm so high right now… I forgot I was watching this video and thought I was creating string theory in my head

    He got the Heisenberg uncertainty principle mistaken for the observer effect. A common fluke and can go unnoticed but the difference between the two is the Heisenberg uncertainty principle states that the more precisely the position of some particle is determined, the less precisely its momentum can be known, and vice versa. This sounds simple because it is. This is just one of its implications but the generic explanation is that it is any of a variety of mathematical inequalities asserting a fundamental limit to the precision with which certain pairs of physical properties of a particle, known as complementary variables or canonically conjugate variables such as position x and momentum p, can be known or, depending on interpretation, to what extent such conjugate properties maintain their approximate meaning. The observer effect in simplest form states that measurements of certain systems cannot be made without affecting the systems, that is, without changing something in a system. As stated in the video to see something is to interact with it, an active process, certain things can be altered by said interaction.

    The more I understand science the more of believer I become. Science just doesnt offer any explanation and only God is our only strength in darkness. Its more and more sure this all is not accident.

    So electrons are a type of lepton? What are the other Leptons?

    String theory may be true, but maybe knot.

    It's 03:26 AM. Why am I blowing my mind like this? Just joking… I love thinking deeply.
