Reply August 12, 2019 at 1:05 pm WOW Reply August 12, 2019 at 3:36 pm Still waiting for the evicdence to overtake the speculations… Reply August 12, 2019 at 4:06 pm And what makes up the strings? Who cares as long as we keep getting grant money to pay for my condo. Reply August 12, 2019 at 9:32 pm you're a fucking idiot, the two realities. Reply August 12, 2019 at 10:52 pm it is now 2019 – have these experiments thrown. any more light on the string theory being true? Reply August 13, 2019 at 10:29 am It's somehow surprising to listen to the words of a very smart guy and be unable to make any sense out of it, showing you that intellect and truth are not always on the same page. This is absolute non-sense. TED talks were crap 10 years ago, they are still garbage now. Reply August 13, 2019 at 8:36 pm I can conveniently say that these guys are reversing the relativity theory of Einstein. The lower dimensions of energy they're looking for will only be a reality if their cyclotron can send the particles at the square of the speed of light. At the speed of light, I'm afraid that the gamotron energy level may never be attained. This is because light itself, made of photons are particles in our own dimension. The square of its speed could very well be potent to hit anything off into other dimensions. So I suggest they need to improve on that cyclotron machine. Reply August 14, 2019 at 6:50 am where r the dimensions bra? Reply August 14, 2019 at 6:54 am if you beam energy into the extra dimensions u might upset the tiny aliens living there. Reply August 14, 2019 at 6:57 am what is interesting is does space itself in 3d depend on 10d structure or does 3d structure determine 10th dimensional structure? Reply August 14, 2019 at 1:46 pm #epicfraud Reply August 14, 2019 at 1:47 pm Theoretical physics is the bane of our contemporary existence. Reply August 15, 2019 at 2:34 am The brilliant physicists like Greene, need to solve Climate Change, otherwise, nothing else matters. Reply August 15, 2019 at 2:22 pm Where was this guy when I was taking organic chemistry in college?? Reply August 15, 2019 at 4:41 pm Did they ever do that experiment that he mentions towards the end of the video? Reply August 16, 2019 at 1:53 pm This was published in April 2008. Prof Greene said experimentation over 'the next 5-7-10 years or so' would show whether the hypothesis described here is correct. We're in August 2019 now, so how's it going? Do those thingies colliding with each other release energy into another dimension, or not?I see someone else asked pretty much the same question a couple of weeks ago. Can anyone comment? (Other than to suggest he may have been referring to 5 to 10 years of some other-dimensional time..) Reply August 16, 2019 at 8:18 pm This is my religion Reply August 17, 2019 at 9:53 am So, what is energy? Does it "exist" or is it a metaphor? Reply August 17, 2019 at 10:49 pm I have always wondered how these people who think about such principles are then able to switch their mind to the mundane such as a grocery list, sorting laundry, and such. Reply August 18, 2019 at 2:29 pm Here's a video that represents a fresh take on the creation / evolution debate and is something I am sure you will find thought-provoking. https://www.youtube.com/watch?v=WYh_kvSyGzk Reply August 18, 2019 at 4:34 pm What is a string made from? What is a particle made from? What is a force made from?These abstract entities may mimic reality but they do not begin to help us understand the true nature of reality. Reply August 18, 2019 at 5:58 pm theory of the week this one will be tossed in favor of a new one in no time. meh Reply August 19, 2019 at 1:35 pm Theory isn’t science Reply August 19, 2019 at 10:32 pm I’m 4 mins in. But Einstein just had to invent a particle called a bosun to explain how an object exerts gravitational influence on another. No? Maybe I need to study the theory in depth and mathematically to see what the actually said.The 2D representation relying, ironically enough, on gravity in the 3rd dimension to help us intuit the effect of curved space just doesn’t do anything for me. Because it’s so fake. Ok so in 3D sure space can be curved.Now tell me how that ‘transmits’ gravitational forces?Sorry Brian! Reply August 19, 2019 at 10:43 pm I have a question. Why is going for a UNIFIED theory an assumed goal?Why not have everything different? Where does this assumptive end goal come from?Is it a deep spiritual logical / intuition that the nature of reality is ONENESS? Reply August 19, 2019 at 11:05 pm Jesus christ, this is what everyone person should strive for, the pursuit of intellect. Reply August 20, 2019 at 1:26 am How does one make sense of nonsense? At least the video says at the beginning that no one of this is true or not. Einstein was wrong about everything. He invited nothing, and holds no patents. Reply August 20, 2019 at 3:49 pm 3:03 I'm rolling on the floor, wait… wait I can't get up. Gravity is pulling me into a circle that doesn't exist. Warped brain power should get me out! SHAZAM! A disk of nothing space did the trick. 3:32 I just tested here on my floor. It does work because I did get up! 5:30 Amazing facts and non-disputable logic. Reply August 20, 2019 at 3:54 pm String theory merely hypothesizes the unexplained instead of giving God His due. Reply August 21, 2019 at 4:19 am I do not believe in Gravity. New World Order horseshit Reply August 21, 2019 at 4:34 pm However it would not be an explanation– it would be a description. Reply August 21, 2019 at 8:01 pm It's more than 10 years on and I don't recall hearing about this from CERN. Anyone know better? Reply August 22, 2019 at 4:30 pm I am not a physicist, but a musician. What are plucking those strings, or are you saying they vibrate on their own? I know you are saying that their geometry my dictate the atomic structure, but why are the strings vibrating already? Is that a dimensional artifact… I mean is the wind blowing the horn a constant? Reply August 22, 2019 at 11:51 pm Cheese.

I mean of the traditional type, not the type that seems popular today. Reply August 24, 2019 at 4:23 pm God says "Worlds without number have I created." And it's based on obedience, which keeps order. And how can there be obedience with intelligence? I would exhort anyone who understands these simple principles to read the Book of Mormon. The answers and understanding are explained in simple form. Truth never changes. Reply August 24, 2019 at 4:37 pm Y r ppl laughing,..that's how I learnt to swim Reply August 25, 2019 at 3:20 pm CAN A DIMENSION BE LOOKED AT AS A VALUE OR DEFINITION? Reply August 25, 2019 at 3:26 pm CAN A FOURTH DIMENSION COME FROM OBSERVING SOMETHING WITH DIFFERENCE IN TIME OR GRAVITY Reply August 25, 2019 at 7:35 pm Thank you Mr. Greene. Reply August 25, 2019 at 10:05 pm The String Theory (actually a mathematical construct, not a theory at all). ST like most theoretical physics is as imaginary as religion. Reply August 26, 2019 at 2:09 am Where on earth that it's sitting on the gravitational wave that is inaccessible to anyone? None! Therefore the existence of gravitational wave must be a bluff! Einstein's famous equation, E=mc^2 is wrong otherwise garbage also can be used to make nuclear bombs as long as it is matter or it has mass. Energy and matter can't interchange one another according to Einstein's famous equation. One must have photons before one can emit out photons. Photons are particles and they have mass. All forms of EMWs including light and heat are dynamic photons per volume per time in different saturations. Therefore the law of conservation of matter, the law of conservation of energy and the law of conservation of charge must always be true in any conditions. Since string theory doesn't comply to the law of conservation of matter, the law of conservation of energy and the law of conservation of charge, therefore it must be wrong. If you are interested in real discoveries, I would recommend you to read my book, The Unification Theory – Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust. Reply August 26, 2019 at 4:37 am I say his theory is all bullshit. Now prove me wrong. Reply August 26, 2019 at 8:30 pm Guy's come a long way since 90210. Reply August 27, 2019 at 12:14 am I place more trust in the proven fundamentals of vel-cro theory myself because no matter what anybody says to the contrary..no matter where I go..there I am. facts Reply August 27, 2019 at 9:36 pm Well said. Reply August 28, 2019 at 5:05 am Ok got it. Reply August 28, 2019 at 6:16 am Gravity is just a theory, no such thing Reply August 28, 2019 at 7:24 am I'm lost….in the last few minutes, was he explaining ejaculation and fertilization?? Reply August 29, 2019 at 1:59 am I think there were 780 people that came looking for cats with STRINGS and were confused. Excellent video! Reply August 29, 2019 at 4:53 am Brian Greene is the best thing happened to this world. Reply August 29, 2019 at 10:25 am There are more dimensions of the dimensions and it is like a rabbit hole 🕳. Reply August 30, 2019 at 4:01 am String theory is not answering the original question. If you do have to step outside the known dimensions then your string theory is no longer about reality Reply August 30, 2019 at 5:20 am What a bs! Reply August 30, 2019 at 12:35 pm Quantum field is more fundamental than space, time, big bang/big bounce, inflation, dark matter/energy etc. QF can simulate conscious intelligent 'observer', collapsing the field to produce particles/strings, fine tuned to eliminate randomness, achieving determinism, creating the universe and life with perfection and with probability one, implying divine purpose. Reply August 30, 2019 at 6:42 pm A decade old but brilliant and so helpful to understand what has, and has not, happened at CERN. Reply August 31, 2019 at 1:50 pm The best explanation of string theory ever ❤️ Reply August 31, 2019 at 5:09 pm I wonder if this guy ever takes mushrooms to understand the stuff he is teaching first hand. Reply August 31, 2019 at 8:19 pm Kind of answered the question: If they were any other number we wouldn't be here, so the only reality where we'd even be having this discussion is the reality where those numbers lined up perfectly. Reply September 1, 2019 at 2:37 pm Why not first explain gravity empirically before you go off on another unexplainable and dubious assertion. Keep those grants a comin' Reply September 1, 2019 at 3:21 pm this was very interesting, but it sounded to me like a brilliant fellow who made one of the most simple mistakes that is known to man: assuming that if we can't measure where the energy went, that it must have gone into a different dimension. There are way too many assumptions that this reasoning follows. Many a man has been unable to measure where energy went. That does not prove that the energy went into a different dimension. That might simply mean that his/our instruments simply can't detect all the energy that is in our known dimensions. even brilliant people make stupid human logic mistakes too. I'm happy to know that even brilliant people can be so simply mistaken too. Reply September 3, 2019 at 2:51 am I think theres a simple explanation for this quantum field, it is God, it is his essence in the universe because he is everywhere, we can feel him, our electrons tremble in his presence, therefore he is what he is. The eternal essence of the universe scientist are calling "dark energy" because he is a gigantic field of energy that fills the entire universe. No one can explain that beyond the Higgs boson, the God particle there is something else and it's called "spirit" and that is what God is made of: Eternal Spirit. So don't look no more because only God can tell us everything there is to know. So seek him in spirit and truth and you will understand all. Reply September 4, 2019 at 1:24 am se how d string, came down to be in 3d, that's all it's there are no more dimensions Reply September 4, 2019 at 6:12 am https://www.youtube.com/watch?v=6RQ6ugMWZ0c&list=PLwgQsqtH9H5c4IXKj82g-Kzbs0EXaq5T3&index=15 In this video I explain why so many physicists believe in string theory but that it also comes with a number of problems. It requires the existence of additional dimensions of space (which we do not see), of new particles (which we do not see), and of new fields (leading to deviations from Einstein's general relativity). It has trouble coping with the cosmological constant and the dream that string theory would be a unique theory of everything has failed due to the discovery of the string theory landscape. Sabine Hossenfelder Reply September 4, 2019 at 7:23 am Brian Greene makes this so interesting & understandable to us ordinary folk.👽Thx Brian Reply September 5, 2019 at 8:17 pm Exactly, not so much electromagnetism, but a combination of intelligent frequency/sound that follows law. It's a privilege to be able to not follow law. That's what sets us apart. Free Will. We are experiencing and event objectively. Reply September 6, 2019 at 5:25 pm Nikola Tesla said Einstein got it wrong, if i'm not mistaken. Tesla said there is no such thing as space, that everything is energy.

It's Chicken man! Reply September 10, 2019 at 11:56 am there's 12 dimensions and a 13th is in the making Reply September 10, 2019 at 3:32 pm Unified Strings 21 or 19 Dimensions & Aspects of Spacetime is physics' 'Theory of Everything', yet it falls under the umbrella of GOD=7_4 or FOD=6_4 (on Planet Nestor). See http://GOD704.wikia.com . Atheists hate this. Reply September 10, 2019 at 7:35 pm I agree somewhat with this guy. With the string theory it's quite amazing that it's a quantum deduction of the effect of ray tracing the trajectory across it's shortest route to enable the cross compatible light source from the angle of interruption. Reply September 10, 2019 at 9:34 pm christ Reply September 11, 2019 at 11:10 am String theory needs to be re-named to String-hypothesis: Zero predictions, zero repeatability, zero falsifiable statements…. ThIs is RELIGION, disguised by some incidentally useful math as science. String Theory does NOT exist, it is barely a hypothesis afet more than 20 years in the hands of the smartest on the planet…yes, they have an ego too….

Reply September 19, 2019 at 1:23 pm Incredibly perspicuous Reply September 20, 2019 at 10:00 am Good speaker BUT…nothing more behind that string(theory should correctly be called hypothesis) has produced exactly zero evidence till now(2019). 11 years and lots of very complicated experiments later, Einstein has been prooved a couple of times more but non extra dim has turned up or anything else! Reply September 21, 2019 at 9:12 pm Even if energy drifts away, it may not be going into another dimension, but more like a chemical discharge or reaction into something else that we can not see or calculate yet. always because it is to small. So even if energy were to drift away it still wont prove multiple dimensions. —– String theory if true might be cool; I could all of a sudden move into another dimension where I am rich if I were able to manipulate it correctly. — But to me its more plausible only one dimension with just smaller reactions that we can not see or calculate yet with todays technology. Reply September 22, 2019 at 10:31 am Excellent!!! I love Brian Greens explanation on Super-Strings. Actually i am suprised he did. Now we all have to become mature enough understanding that the Strings ARE our thoughts. A thought, a intent , a decision IS indeed a string creating electrons and worlds. Well, actually for gods sake it is a snake biting its tail.I guess the hard part is to PROVE it in math – lol.Imagine, frontal lobe messing with strings – bored to death – house is full of dust. Did you ever try to clean a house and wonder where all this f…dust come from?And, Mr.Green your true talent is explaining highly complex matters to plain people – well done! Reply September 22, 2019 at 9:13 pm I heard these more dimensions ideas were only invented to make the math come out. That came from a very reliable source, Lenard Hofstadter. He's a genius so I think he would know. Then of course when Sheldon claims they are there, he's just defending his research. Reply September 22, 2019 at 9:20 pm Well we got dimensions x,y,z,t, and the rest are something in the mind of the inventor, sorry.

To date, no supersymmetric particle has been found. String theory also predicts a scalar boson, called the graviton, that mediates gravitation. To date, the graviton has yet to be found.
