[@canesvenatici9588]

Yes. But, how they vibrate and each of those 10 dimensions are defined wasn't explained. Makes me question more and more. Is it really just a working theory or could it potentially be real but we just haven't measured anything into those dimensions to prove anything? Maybe I should learn physics it's way more interesting than what's being taught in high school. I suppose it would take a very long video to explain them all but it is indeed a good introductory video.

[@cicholasnage]

i guess kurzgesagt is just trying to make the video as compact and understandable as possible, and explaining further may overwhelm some people. Yes, i do think physics is very interesting, though, i do need to warn you that it only looks cool from the outside, the visualization of concepts and theories. But to actually comprehend the theories itself, you need to do extensive extreme hard works with studies, and have to be proficient in maths & calculus. Keep in mind that, even geniuses like Einstein, bohr, oppenheimer (all of them supposedly have an iq of 170+) are still boggled with some of the general theories of quantum physics...

[@Sam_596]

In chemistry class, we learned about the history of the various models of the atom. They were all wrong to one extent or another, but they were still useful to think about, and I think worth learning about.

Ultimately and truly, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. OVERLAY what is THE EYE in BALANCED RELATION to/WITH what is THE EARTH. Notice the black space of THE EYE. The stars AND PLANETS are POINTS in the night sky. THE DOME of a person's EYE is ALSO VISIBLE. Now, carefully consider what is the semi-spherical, translucent, QUANTUM GRAVITATIONAL, AND BLUE SKY. Great. E=mc2 IS F=ma. It is CLEAR. Time DILATION ULTIMATELY proves (ON BALANCE) that E=mc2 IS F=ma, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=mc2 IS F=ma; as ELECTROMAGNETISM/energy is gravity. 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; as E=mc2 IS F=ma; as ELECTROMAGNETISM/ENERGY IS GRAVITY. The stars AND PLANETS are POINTS in the night sky. The EARTH and the Sun constitute and comprise the MIDDLE AND THE FULL DISTANCE in/of SPACE (IN BALANCE) in full and BALANCED compliance and conformity with the CLEAR and universal fact that E=mc2 IS F=ma, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Great !!!!!! Hence, it is CLEARLY proven, in fact, that the rotation of WHAT IS THE MOON NECESSARILY matches it's revolution. Great. Obviously, what is THE MOON is subject to and constitutive of both E=mc2 AND F=ma. E=mc2 IS CLEARLY proven to be F=ma. "Mass"/energy involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=mc2 IS F=ma. This CLEARLY explains why objects fall at the SAME RATE (neglecting air resistance, of course), AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. THE EARTH is ALSO F=ma AS E=mc2. The Sun is both F=ma AND E=mc2. The BLUE SKY is E=mc2 AND F=ma. What is THE MOON is NECESSARILY F=ma AS E=mc2. THINK. It ALL CLEARLY makes perfect sense. (BALANCE and completeness go hand in hand.) VERY IMPORTANTLY, outer "space" involves full inertia; AND it is fully invisible AND black. Great !!! INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. The INTEGRATED EXTENSIVENESS of THOUGHT (AND description) is improved in the truly superior mind. (THOUGHTS ARE INVISIBLE.) GREAT. THE DOME of a person's EYE is ALSO VISIBLE. The balance of being AND EXPERIENCE is essential. The EARTH is ALSO BLUE (as water). Alas, the ULTIMATE unification of physics/physical experience combines, BALANCES, AND INCLUDES opposites; as ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=mc2 IS F=ma. Gravity IS ELECTROMAGNETISM/energy.

For those of you still confused, here is an elementary breakdown of String Theory and what was said in the video. It’s a little lengthy but I guarantee you’ll be able to understand it (Or at least I hope) Once upon a time we thought the smallest, most fundamental thing that makes up everything, was the atom. We now know that you can get smaller (and more fundamental if you will) than that. It turns out that the atom is made up of 3 particles: Proton, Neutron, and the electron. For awhile, we thought that was as small as you could go. But we now know that the Proton and Neutron are made up of smaller particles called Quarks (we’re pretty sure that the electron is fundamental and nothing makes up the Electron other than energy… So now we ask ourselves, what is more fundamental than a Quark? What is smaller? In other words, what makes a Quark? Is it another particle that’s even smaller? We don’t know. This is where String Theory comes in. String Theory suggests that it does get smaller. The tiniest, most fundamental building blocks of matter and the universe are tiny strings. Little filaments of energy that vibrate and dance around (as seen at 5:01). And every fundamental sub atomic particle in the universe was made by these vibrating strings. If a string vibrates this way, then an electron is made. If it vibrates another way, then a Quark is made. If it vibrates in another way, then a neutrino pops out… so on and so on It also turns out that the math behind String Theory tells us that our Universe has 10 dimensions instead of just the 4 that we know. 9 spatial dimensions and 1 temporal dimension (AKA time). When these strings vibrate, they aren’t just vibrating in our 3 dimensions (up/down, left/right, forward/backward). Instead they are vibrating in 9 different dimensions. I dare not try to explain this further SIDE NOTE: There seems to be confusion as to whether String Theory suggests that there are 10 or 11 dimensions. It depends on if you are talking about “classic” String Theory or a similar version of String Theory called “M-Theory” One of them typically states 10, the other 11. It also depends on the source you look at. Some sources use those two theories interchangeably. It’s all kinda confusing To also add one more thing that is very important…. The thing scientists are most interested about concerning String Theory is less of anything I mentioned above but instead something called “Quantum Gravity” Einstein’s Theory of General Relativity is extremely accurate and has been one of the most useful tools for understanding the universe around us. But it only answers problems for all the large scale things in the universe: Gravity, Black Holes, Time, Light etc… The other side of the coin is Quantum Mechanics. Which deals with all of the smallest things in the universe: Atoms, subatomic particles, a whole bunch of other behaviors and phenomena at very tiny scales, etc… Relativity and Quantum Mechanics are the two most accurate and all-encompassing branches of science known to Man. However, they don’t work together. Quantum Mechanics doesn’t work with large scale stuff and Relativity doesn’t work at Quantum levels. So you might think that one of them obviously has to be wrong then. But they aren’t. Again, there is no problem scientists have ever thrown at these two fields that doesn’t get solved, except when you try to marry the two together. Bringing the two together successfully is something called “Quantum Gravity”. If we can figure out Quantum Gravity, that will probably be the biggest discovery ever made in history. At least one of them. It would help us solve everything (loosely speaking). There is nothing more mouth-watering to scientists than Quantum Gravity. It just so happens that if String Theory is true and we can figure it out, it would solve for this Quantum Gravity problem. That’s mostly why String Theory is so enticing to scientists. More so than the other cool stuff I mentioned a bit earlier. It would win whoever figured it out a lifetime of Nobel Prizes! (I’m being a bit dramatic of course, but you get the idea! lol) Keep in mind, when ST was first proposed, scientists were watering at the mouth. But even to this day there is no real proof/evidence that these Strings exist. And because of that, ST is kinda becoming a joke. Day by day, ST is taken less seriously than before and a lot of physicists (like Brian Green) essentially get told to move on and forget it (roughly speaking). Other than some fancy mathematics, there hasn’t really been anything to show us that it is real EDIT: I keep adding on to this. Hopefully this is the last addition. String Theory is also known as “The Theory of Everything” for obvious reasons. Also, earlier I mentioned that Quarks are the smallest particles that we know of. But I kinda made it sound like there was only one type of Quark. Let me clarify and mention that there are 6 types of Quarks that exist in the universe: Up, Down, Top, Bottom, Strange, and Charm Quarks Protons are made out of two types: 2x Up Quarks and 1x Down Quark Neutrons are the opposite: 2x Down Quarks and 1x Up Quark EDIT AGAIN: Earlier I said that the electron is essentially just made up of energy. To clarify, more accurately speaking, it’s a negative electrical charge that exists as a cloud of probability in certain orbitals around the nucleus. Ya it’s kinda confusing. The Bohr model of the electron was that the electron was a point particle that orbited the nucleus in discreet orbital shells. This is the classical simplified model that we’ve all learned in school. Quantum mechanics gave us a more accurate understanding that tells us that model is inaccurate and it instead works the confusing way I explained a few sentences ago. The point is that no one has ever seen an electron and we are pretty sure nothing smaller makes up one EDIT AGAIN: There’s a few other juicy answers I gave down in the replies when someone asked me a follow up question… if you’re interested NOTE: If you need clarification on what I meant by…. “However, they don’t work together. Quantum Mechanics doesn’t work with large scale stuff and Relativity doesn’t work at Quantum levels…” Feel free to ask and I’ll be sure to elaborate!

I hope everyone that these words helps to better understand..(extremely long explanation ahead).. String theories In these theories the basic objects are not particles that occupy a single point of space. Rather, they are things that have a length but no other dimension, like an infinitely thin loop of string. A particle occupies one point of space at each instant of time. Thus, its history can be represented by a t line in space-time called the "world-line." A string, on the other hand, occupies a line in space at each moment of time. So its history in space-time is a two-dimensional surface called the "world-sheet." Any point on such a world-sheet can be described by two numbers, one specifying the time and the other the position of the point on the string. The world-sheet of a string is a cylinder or tube. A slice through the tube is a circle, which represents the position of the string at one particular time. Two pieces of string can join together to form a single string. It is like the two legs joining on a pair of trousers. Similarly, a single piece of string can divide into two strings. In string theories, what were previously thought of as particles are now pictured as waves traveling down the string, like waves on a washing line. The emission or absorption of one particle by another corresponds to the dividing or joining together of strings. For example, the gravitational force of the sun on the Earth corresponds to an H-shaped tube or pipe. String theory is rather like plumbing, in a way. Waves on the two vertical sides of the H correspond to the particles in the sun and the Earth, and waves on the horizontal crossbar correspond to the gravitational force that travels between them. String theory has a curious history. It was originally invented in the late 1960s in an attempt to find a theory to describe the strong force. The idea was that particles like the proton and the neutron could be regarded as waves on a string. The strong forces between the particles would correspond to pieces of string that went between other bits of string, like in a spider's web. For this theory to give the observed value of the strong force between particles, the strings had to be like rubber bands with a pull of about ten tons. In 1974 Joël Scherk and John Schwarz published a paper in which they showed that string theory could describe the gravitational force, but only if the tension in the string were very much higher-about 10" tons. The predictions of the string theory would be just the same as those of general relativity on normal length scales, but they would differ at very small distances-less than 10 centimeters. Their work did not receive much attention, however, because at just about that time, most people abandoned the original string theory of the strong force. Scherk died in tragic circumstances. He suffered from diabetes and went into a coma when no one was around to give him an injection of insulin. So Schwarz was left alone as almost the only supporter of string theory, but now with a much higher proposed value of the string tension. There seemed to have been two reasons for the sudden revival of interest in strings in 1984. One was that people were not really making much progress toward showing that supergravity was finite or that it could explain the kinds of particles that we observe. The other was the publication of a paper by John Schwarz and Mike Green which showed that string theory might be able to explain the existence of particles that have a built-in left- handedness, like some of the particles that we observe. Whatever the reasons, a large number of people soon began to work on string theory. A new version was developed, the so-called heterotic string. This seemed as if it might be able to explain the types of particle that we observe. String theories also lead to infinities, but it is thought they will all cancel out in versions like the heterotic string. String theories, however, have a bigger problem. They seem to be consistent only if space-time has either ten or twenty-six dimensions, instead of the usual four. Of course, extra space-time dimensions are a commonplace. of science fiction; indeed, they are almost a necessity. Otherwise, the fact that relativity implies that one cannot travel faster than light means that it would take far too long to get across our own galaxy, let alone to travel to other galaxies. The science fiction idea is that one can take a shortcut through a higher dimension. One can picture this in the following way. Imagine that the space we live in had only two dimensions and was curved like the surface of a doughnut or a torus. If you were on one side of the ring and you wanted to get to a point on the other side, you would have to go around the ring. However, if you were able to travel in the third dimension, you could cut straight across. Why don't we notice all these extra dimensions if they are really there? Why do we see only three space and one time dimension? The suggestion is that the other dimensions are curved up into a space of very small size, something like a million million million million millionth of an inch. This is so small that we just don't notice it. We see only the three space and one time dimension in which space-time is thoroughly flat. It is like the surface of an orange: if you look at it close up, it is all curved and wrinkled, but if you look at it from a distance, you don't see the bumps and it appears to be smooth. So it is with space-time. On a very small scale, it is ten-dimensional and highly curved. But on bigger scales, you don't see the curvature or the extra dimensions. If this picture is correct, it spells bad news for would-be space travelers. The extra dimensions would be far too small to allow a spaceship through. However, it raises another major problem. Why should some, but not all, of the dimensions be curled up into a small ball? Presumably, in the very early universe, all the dimensions would have been very curved. Why did three space and one time dimension flatten out, while the other dimensions remained tightly curled up? One possible answer is the anthropic principle. Two space dimensions do not seem to be enough to allow for the development of complicated beings like us. For example, two-dimensional people living on a one-dimensional Earth would have to climb over each other in order to get past each other. If a two-dimensional creature ate something it could not digest completely, it would have to bring up the remains the same way it swallowed them, because if there were a passage through its body, it would divide the creature into two separate parts. Our two- dimensional being would fall apart. Similarly, it is difficult to see how there could be any circulation of the blood in a two-dimensional creature. There would also be problems with more than three space dimensions. The gravitational force between two bodies would decrease more rapidly with distance than it does in three dimensions. The significance of this is that the orbits of planets, like the Earth, around the sun would be unstable. The least disturbance from a circular orbit, such as would be caused by the gravitational attraction of other planets, would cause the Earth to spiral away from or into the sun. We would either freeze or be burned up. In fact, the same behavior of gravity with distance would mean that the sun would also be unstable. It would either fall apart or it would collapse to form a black hole. In either case, it would not be much use as a source of heat and light for life on Earth. On a smaller scale, the electrical forces that cause the electrons to orbit around the nucleus in an atom would behave in the same way as the gravitational forces Thus, the electrons would either escape from the atom altogether or it would spiral into the nucleus. In either case, one could not have atoms as we know them. It seems clear that life, at least as we know it, can exist only in regions of space-time in which three space and one time dimension are not curled up small. This would mean that one could appeal to the anthropic principle, provided one could show that string theory does at least allow there to be such regions of the universe. And it seems that indeed each string theory does allow such regions. There may well be other regions of the universe, or other universes (whatever that may mean) in which all the dimensions are curled up small, or in which more than four dimensions are nearly flat. But there would be no intelligent beings in such regions to observe the different number of effective dimensions. Apart from the question of the number of dimensions that space-time appears to have, string theory still has several other problems that must be solved before it can be acclaimed as the ultimate unified theory of physics. We do not yet know whether all the infinities cancel each other out, or exactly how to relate the waves on the string to the particular types of particle that we observe. Nevertheless, it is likely that answers to these questions will be found over the next few years, and that by the end of the century we shall know whether string theory is indeed the long sought-after unified theory of physics. And Sin bad thanks for your guidance!!

@@SoapinTrucker From an article written about Kurzgesagt: "Dettmer and Rether write the videos in English, and they use Adobe Illustrator to create detailed storyboards. Dettmer draws every element for the videos and then hands them off to Rether for animation in Adobe After Effects."

[@kurzgesagt]

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.
