Making sense of string theory | Brian Greene

www.ted.com In clear, nontechnical language, string theorist Brian Greene explains how our understanding of the universe has evolved from Einstein's notions of gravity and space-time to superstring theory, where minuscule strands of energy vibrating in 11 dimensions create every particle and force in the universe. (This mind-bending theory may soon be put to the test at the Large Hadron Collider in Geneva).

    Einstein was a known weasel. Greene is knowingly and deceitfully lying about physics. WHY E=MC2 IS NECESSARILY F=MA (ON BALANCE), AS ELECTROMAGNETISM/energy is gravity AS SPACE ON BALANCE: TIME DILATION ULTIMATELY proves ON BALANCE that E=MC2 IS F=ma, as ELECTROMAGNETISM/energy is gravity. The stars AND PLANETS are POINTS in the night sky. TIME is NECESSARILY possible/potential AND actual IN BALANCE, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Hence, the Earth AND the Sun are CLEARLY E=MC2 AND F=ma IN BALANCE. (The sky is blue, AND the Earth is ALSO BLUE.) A PHOTON may be placed at the center of WHAT IS THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the speed of light (c); AS E=MC2 IS F=MA !!!; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. BALANCE and completeness go hand in hand. It ALL CLEARLY makes perfect sense. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. ("Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/energy is gravity !!!) Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=mC2 IS F=ma IN BALANCE !!!; AS ELECTROMAGNETISM/energy is gravity. (Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE.) E=mC2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. Great !!! Again, BALANCE AND completeness go hand in hand. It ALL CLEARLY makes perfect sense. By Frank DiMeglio

    Brain Greene is actually misleading people. He was time & again asked to read the link www.linkedin.com/pulse/adopted-paradigm-physics-incorrect-shafiq-khan?trk=pulse_spock-articles before he talks about physics in any forum. Einstein was the greatest scientific trickster ever. Theories of relativity lead to Big Bang Theory whereas under Big Bang paradigm there is absolutely no possibility of existence of God for following reasons. 1. Philosophically for existence; it has to be some substance (visible, invisible, perceivable or not perceivable) and this applies to God also. Substances occupy space but there is absolutely no space for God to exist at the time of Big Bang & before. 2. Four things come out of Big Bang namely space, time, matter & light/radiation. We cannot look for eternal God in space & time as both had the beginning; secondly humans are in a position to produce all types of light/radiation and something which humans can produce could not be the God and since matter is made up of electrons, protons & neutrons these too could not be the God. However Big Bang Theory including Cosmic Inflation has been mathematically, theoretically & experimentally proved as baseless in the published paper "Experimental & Theoretical Evidences of Fallacy of Space-time Concept and Actual State of Existence of the Physical Universe" which is available at the journal site at indjst.org/index.php/indjst/issue/view/2885.

The man on ACID got it right.

    You want to know what's trippy? Everything has gravitational pull, even humans. Our pull is small because we don't have that much mass but we emit gravitational pull regardless. So right now as you sit by your computer you are effecting space fabric. Everywhere you go and everything you do you are warping the fabric of space. Everything you do from taking a breath, to scratching your balls eventually effects everything in the universe in some way or another. By typing this right now I will eventually effect everything in the universe, even a planet hundreds of million light years away that may have a person identical to me typing this very same thing. That's not to say it will be a huge change, maybe just a displacement of a molecule or a microscopic reaction, but it's a change nonetheless.

    Nope, you won't effect anything you don't directly touch. Unless you're in space, all other forces are superior to gravity. Not even the earth's gravity can dislodge an atom. If there was no nuclear attractions, or friction, and you stood still for a few weeks, you might notice small objects have made the smallest of movements towards you. But that is not the case, the light waves that just bounced off of you and back into outer space will have more of an effect on something than your gravity.

    FrankCoffman This article you posted is from 2007. The scientists at CERN have discovered the Higgs Boson last year. This proves that the mathematical theories of String Theory are accurate as their experimentation meet their projected calculations. We have the Standard Model of Fundamental Particles because of String Theory, and as time goes on, we are finding more and more particles that we are expecting to find from this theory. If this theory is wrong, then why are we keep finding good results and able to make practical use from it under the assumption it is correct? Now I will admit that my level of understanding of physics isn't high enough yet to fully understand String Theory (still an undergraduate in college), but from my understanding, this is new stuff that the scientific community is just starting to accept as fact in an age where all physics textbooks are wrong, as Michio Kaku points out, because they all say "The Universe is mainly made out of atoms," when we know that about 96 percent of it is Dark Matter and Dark Energy.

It's not like creationism which is plain stupid because it's based on an old unscientific book, this is resting on and derived from the body of science. I mean, it must be the best current explanation since a lot of very smart people, who understand stuff that you and i don't, dedicate their time and carrier to it. Even if not all physicists agree with it, it is still unwise to dismiss it before giving it a fair trial. AND if it turns out to be wrong, some smart people would have spent their time, thinking about a major theory for some time for a scientific reason, and i don't really see how that is a problem. If you have any VALID argument for ridiculing the super-string-theory, bring them on. I don't think you have.

From the animations it looks like these 11 dimensions are just things existing in three dimensions but on a really small scale. If they operate in all 11 dimensions I guess they could be "seen" in our three dimensions of space too, but. Can these strings really be visualised? Does it even matter what they look like?

    I just had an idea. I know I am not very smart at this type stuff but maybe this explains black holes? ok so if the proton collider gets particles to crash into each other at nearly the speed light and you have less of material to begin with it will mean some of the material went into a different dimension. Just a thought but Maybe black holes are so strong they get light particles to crash into each other and instead of getting some of the matter to "push through" are dimension like the proton collider does...a black hole actually a punches a hole in our dimension? We know that some matter that goes into a black hole disappears and cant be accounting for , so does black holes prove that we have many dimensions?

    My particle is a circle. When this circle started to curl around itself its form changed. Now it has volume and looks like a sphere. What is the law between particle’s volume and energy? I think: big volume - low energy, small volume - high energy. The more speed / impulse--> the more particle (as a volume) compress--> the more energy . And when the speed decrease - - the energy decrease too - but the volume of particle will increase. My particle behaves like ‘ a springy circle’ (!) This springy circle can curl into small sphere which must have volume and therefore can be describe as a ‘stringlike particle with vibrations’ only approximately . Springy particle - it means the particle is able to spring back into its former position. In my opinion this is the meaning of ‘ The Law of mass/energy conservation and transformation’ ======== Once more. Quantum of light has potential energy (- E=Mc^2 ). When it starts to curl around its diameter the potential energy (- E=Mc^2 ) is hidden and we can observe its electronic energy ( E=h*f). But there is situation when this hidden potential energy goes out and we can see its great active power ( + E=Mc^2 ) looking the destroyed cities of Hiroshima and Nagasaki. In my opinion the particle’s transformation from one state into the other was legalized as ‘ The Law of mass/energy conservation and transformation’. # Different geometrical forms of string particle ( open - closed ), different frequencies of string particle are reason of different radiation (from ultraviolet to infrared ), are also reason of new situation in 2D. Now the surface of my 2D in local area is changed. On one hand it is electromagnetic field now, on the other hand the spinning electron changed the temperature of the surface in local area. Now this local area has Debye temperature: Q(d)= h*f(max) / k. Maybe in this space a grain of gravity theory is hidden. Who knows? ==================.. My conclusion. It is no bad idea to ask question: what are physical parameters of every new super D? It is possible to understand many things using 2D. The missing ‘big idea’ in ‘String theory’ is hidden in the simple question: ‘ What was the form of particle before it started to curl?’ The time appears as a period of electron’s action. I ‘mix bosons with fermions’ (page 105) without using any supersymmetries. And I have: a) In potential state the impulse of particle is h = 0. ( boson) b) Having Planck’s inner impulse (unit h=1) my particle moves straight with constant speed c=1. ( photon) c) Having Goudsmit / Uhlenbeck inner angular impulse h * = h /2pi. the particle rotates around its diameter. ( electron/ tachyon/ fermion). Maybe the different conditions of (h) is the key to all other phenomena. Maybe this process can explain ‘the dualism of particle.’ Maybe this interpretation can explain where the energy comes from. Maybe, if the space of my circle curls and changes then we need to use Riemann geometry . Maybe, if the speed of the particle is independent and self-contained then we need to use nonlinear equations. Maybe . . . . . Maybe it is time to end now. I reread my article. It is not bad, not bad for amateur, who thinks about philosophy of physics for 28 years. Of course, my interpretation is only scheme. And if I were a physicist I would make from this scheme a theory '' Elementary particle as a membrane-circle = pi = 3,1415 . . . . ''.

    I'm just curious about why these other dimensions all have to be so SMALL that we can't see them with our eyes or other currently created observational technology? Is there the possibility that they are so LARGE that we can't observe them? Like how at one point we thought the Earth was flat because we couldn't observe the curvature of the Earth. There could be some obvious reason that I'm missing - science and mathematics aren't my strong suit - but if anyone cares to explain this to me I'd appreciate it :).

    The dimensions are small because we are looking deeper into the particles of the particles within an atom. Greene explained how there's a machine in which scientists are colliding particles to observe the results of the collisions. This video was five years ago. In 2012, scientists discovered the Higgs Boson, which is the result of these collisions, so indeed the dimensions are small.

We know 3 of us space and the 1 of time already leaving 7 dimensions of space unknown to us. The size of these dimensions are immaterial if I am not wrong. Dimensions are not bound by physical targets. It is the features and characteristics that matter. A line (2D) can be long or short. Height can be tall or short. Time can be measured but it is not bounded. Hope you get the point :)

    Maybe it's just me but I don't find the "spatial valley" model of gravity all that satisfying. The idea is that material bodies warp space and attract other bodies because of that curvature. Doesn't this already rely on our intuitions about how things "roll down hills", though? In other words, the intuitive explanation of gravity appeals to examples that already operate with some kind of folk-gravitational model. The question remains: why do bodies react at all to the bending of space?

    Yes. I see tons of comments about 'you can't explain gravity with gravity' and waited a long time before it was actually explained to me properly. But still coupled with a good explanation it works pretty well as a model, however the true explanation is dumbed down too much (i don't mean we have to go indepth into equations either) so it causes confusion especially in the poor explanation on the video. Its space-time, not just space for a start. its actually 3d plus time in reality. i prefer a rollercoaster track or something, with a rolercoaster that never stops moving-it never stops moving because it has to be going through time or space...and this is space-time....it hits a corner and has to turn that corner (the track being space-time), but also it has to move towards that corner it can't stop...well still not enough dimensions of course(because really you can't), and lacking geometry because of the predetermined path, but its an alternative analogy. and i probably have confused people more.

    I'm with you. Even *****'s pictures seem to still rely on some sort of basic understanding of how physics work. Things kinda slide down curves - in this case not because of gravity, but to cause gravity. But this still pretty much seems like it relies on physics to cause a law of physics to work- circular reasoning. So much of this is still theoretical and we're just kind of testing hypotheses out with other hypotheses. I could almost see there being a fourth dimension or even a fifth, but ten? It really seems like they're just scrounging for ways to make their ideas work at this point. Some people look at this kind of science and reassure themselves that religion is outdated superstition, but I look at so much that we don't know and that doesn't make sense and it reassures me that there's probably something supernatural that's holding it all together. Otherwise so much just doesn't make sense

    Mysteroo Movies Ehh I mean I agreed with that until you jumped to the supernatural. Seems like a classic argument from ignorance to me. Sure a lot of it is just fitting data to theories, but that's what science has always been. It's only this theoretical because, at least I think, we don't yet know enough about the "frame of reference" for all this stuff, conceptually. At this point everything that's known about quantum and theoretical physics seems to be based on predictions. Hypotheses have falsifiable predictions and they work. That's always been the core of science. So I agree with you that it might not "make sense" yet, but that doesn't mean the evidence isn't there. Just not enough is known yet to put it together in a coherent and explanatory treatise. And even if we can never know, I don't think the supernatural elucidates any of this. That's just putting a name on the unknown and I don't think it's very useful. The second we do that is the second we concede that further investigation is basically useless. And any kind of non-physical "mind" out there seems just as absurd as many of the outlandish theories of string theory and quantum mechanics.

    David Burns what would be wrong with saying that God is the string builder? Logically speaking, Christians or other religions believe that God made the universe. They don’t explain how he made it or how it works. That doesn’t mean it’s false, right? If string theory is true that doesn’t disprove God. Just because the Bible never said the earth wasn’t flat but spherical, that doesn’t mean that the Bible is wrong because it never said that the earth wasn’t spherical. Same principle for this in my opinion. If string theory is the most logical explanation for laws of the universe, seems to me that that’s just how God designed it to work. I just don’t think the concepts of science and God are mutually exclusive. In fact, the fact that everything is so orderly and logical seems to point more towards an intelligence than not in my opinion. Anywhozzles😂im sure you weren’t looking for a rebuttal.

Most everythiing I know life and non life can be explained by elements. So while the Standard Model making up the fundamental particles and forces of nature is impressive and an impressive accomplishment, somehow I felt a beauty was lost when it emerged. These days dealing with String Theory, fields, and halograms I feel we are moving to a much colder place.

For a documentary about a topic most people would find tedious and boring, it's actually a well-paced and rather suspenseful film; and like Dr. Greene, it makes an enormously complex topic very accessible to those of us for whom such topics are above our intellectual pay grade. Give it a watch - if you like this TED talk, I'd be surprised if you didn't find PARTICLE FEVER equally compelling. Cheers!

    +Anoop Toffy "what causes it to vibrate?" I am going to try to answer that. Answer: energy. Somewhere I got the concept of what happens inside a quark (2 up quarks and 1 down quark makes a proton) is the most radical lightening storm you could ever image. Also, I got the concept somewhere of what goes on in each of our cells (muscle, skin, etc.). Molecules are zipping around fast and furious. Not like the images that you see everything moving slowly along. Things in the sub-atomic level works different than our everyday experiences. That would be my pseudo-intellectual answer.

    GReaperEx, In 1928, Paul Dirac predicted the possibility of anti-electrons based on theoretical evidence. In 1928, would you have discounted this whole notion of anti-matter? I think you would. You wouldn't be alone. Positrons were discovered in 1932 and Dirac received the Nobel Prize in 1933. One case in a million. Most theories go in the trash can. So what? Are you going to fault every scientist for working on theories that you have not a clue if it's right or wrong. I still don't understand why this theory bothers you.

    +GReaperEx Modern science is to pompous to admit they are delving into what they used to call 'pseudo-science' or 'mysticism' to find answers. Nikola Tesla said,. "If you want to find the secrets of the Universe, think in terms of energy, frequency and vibration." but what made out to be a nut. If you go through the history if scientific discovery you find that all the big names speak highly of ancient teachings, but of course this is rarely, if ever, mentioned these days. Look up the Vedas or Vedic science and see how many scientists attest to their teachings.

It was just put into a more detailed perspective, but no matter how far you stretch this chain at the end of it you will always two things - A. a statement that something is, because it is. B. a question of why is it the way it is? It is by definition inescapable.

    Clear explanation of the unexplicable. Now I finally understand what scientists are talking about. BUT what seems clearer to me is that our universe has only three spatial dimentions linked to time. It is interpenetrated by another three-dimentional universe linked to another time (vibrating in other frequencies), which is interpenetrated by another one linked to another time (vibrating in other frequencies) and so on. Maybe far more than ten interpenetrated universes.

    I've noticed that the dualities of the 5 string theories are similar to the dualities of the 5 Platonic solids: The 5 Platonic solids have 2 pairs of dual "objects" and one "object" that is dual to itself - the cube is dual to the octahedron, the dodecahedron is dual to the icosahedron, and the tetrahedron is dual to itself. The 5 string theories also have 2 pairs of dual "objects" and one "object" that is dual to itself - the SO(32) is dual to the E8xE8, the type IIA is dual to the type IIB, and the type I is dual to itself. I don't know that this means anything of real interest, but I'm neither a physicist or a mathematician, just an interested layman. This just seems to me to be a bit too specific to be nothing but coincidence, but maybe that's all it is.

    You just sound pretentious. People who believe that religion has no benefits or reasons for existence are just as close minded as the religious fanatics that attempt to deny scientific facts. These readings created thousands of years ago offer no value to you because you only observe them at face value and through literal interpretation. You don't stop to think about the insight gained from learning more about ourselves through the past, how we used to behave and how we have changed. Like what string theory implies with dimensions, the usefulness of religion and religious texts is tucked away, hidden, and overshadowed by immediate observations.

    Perhaps, but if you want to argue that religion has caused more good than bad, that's where you'll run into a lot of difficulties. What difference does it make that people derive insight from learning about the past if that insight is equally responsible for them strapping bombs to themselves and blowing up a mall, or committing genocide? No one does that for string theory because there are mathematical derivations to do the arguing for us.

  • @abbadumbotron

    I wasn't arguing that religion has caused more good than bad, that's something I feel is subjective in most cases. What I was arguing is that there is something to be gained in anything from any perspective, as non-eloquent as that sounds. For example, Christianity can provide more than just what the belief system gives. It can teach us more about who we are and where we come from, giving insight into why we hold beliefs and what our desires are. Just because something has caused pain and suffering doesn't mean there cannot be good found in it. My point is that anyone who values knowledge and insight should not claim that anything is unworthy of occupying a neuron in one's mind, because you can always learn.

    I agree with you that the Genesis story is laughable. Much of it was borrowed from earlier texts and largely plagiarized anyway. But there is scientific evidence to support the fact that nearly all human civilizations have some sort of religion... belief in an afterlife is an adaptation of the human brain unable to deal with the notion of it's own mortality. There is a center of the human brain devoted to belief in it's own immortality. Doesn't mean that it's true, only that most people believe it's true. Me personally I will believe what the evidence suggests and not the million year old religious notion encoded into my monkey brain.

Now, I have openned up my mind to the idea that the Bible is not a scientific book and just tries to teach us about Jesus. And the line where 'Where were you when God stretched out the heavens?..' written centuries before Christ seems to indicate or agree with the expanding universe and the creationists' view, not that i believe it a hundred percent. But, makes you wonder, doesnt it ? Please, forgive me if i sound rude. Peace!

    The problem with string theory starts with its motivation - Unification. More specifically with preConceived ideas of what Unification looks like. Unification is the correct goal if the subject can be unified. It is a very bad goal if that is not the case. Try to unify Cuisine (recipes for cookies etc) and the thermonuclear reactions in the Sun. Read my theory to understand how the adoption of the correct paradigm, you can simplify our understanding.
