Dr. Brian Greene wrote about the Kaluza-Klein theory which lead to string theory in his books on the subject. See: "The Hidden Reality" and "The Elegant Universe". The Kaluza-Klein theory is classical in nature and is not necessarily a quantum theory. It tries to explain the unified field theory of gravitation and electromagnetism built around the fifth dimension as a precursor to string theory. Source: Wikipedia. Dr. Greene in his books gives an example of a long rope stretched horizontally from far away where a worm is crawling along the rope. From far away, all we see is a thin line stretched out by two poles from where a rope is attached on both ends. But as we move ever closer we finally see the worm crawling from one side to the other along the entire circumference of the rope. The worm can crawl all around the rope as it travels. As we move very close we can see the "extra" dimensions from the worm's perspective. But from far away we only see a single line. The Kaluza-Klein theory was the original inspiration for String Theory, but it took a long time before anybody made the connection. I was impressed with Brian Greene's books when I first read them many years ago, but now there are several experts who question String Theory. At this point, I don't know who nor what to believe about multiple dimensions. Until the experts can find some communion with the classical world and the quantum world, I'm just a bystander waiting for the next chapter to unfold in our book of so-called "reality".
This is the best explanation of String theory and higher dimensions I have seen so far. Looking forward to the next part. Trying to understand the concept of a circular dimension. What values can it have? Why is it not just a straight dimension of say minus 1 to plus 1.
The real interval from - 1 to +1, considering that the point - 1 is equivalent to +1, that's homeomorphic to S^1, the circle. The same can be done in n dimensions to obtain S^1×S^1×...×S^1 which is a n-torus.
@@johugra1 Imagine a segment in which, when you reach one of its bounds, you appear in the other. That construction is completely equivalent to a circular line. You have to choose a dimension to be compactified or be infinite because you don't want to find a wall while you're moving through that dimension.
@@miguelchamorro953 Thank you Miguel. That is much clearer and rather fascinating. I don't want to waste too much of your time so only one more question, why not have a finite dimension that is straight?
@@johugra1 You could have it, but it's what I said, in that direction there would be an edge, you have to specify and justify what happens there. Another point is that in that dimension homogeneity is lost, because things would be different depending on your distance to the boundary.
Strings are not the fundamental building blocks of spacetime, mass, energy, momentum, position, etc. But try Planck action points that start at a point, and expand at the speed of light.
I remember reading that if there were extra dimensions, the gravitational waves from merging black holes we would get would be less powerful, because some of the waves would go along the direction of these extra dimensions. But when we measured gravitational waves, they were the strength we'd expect from 3 spatial dimensions. Does that mean that there actually aren't extra dimensions, or is there some reason this doesn't actually work?
Would extra dimensions help describe why we observe quatum particles as waves or clouds of statistically most probable location, while they move quite predictabley to an observer who can detect all dimensions?
Since we know we’re in a sea of dark matter that doesn’t interact with us (baryonic matter)(but for gravity), could it be considered to be on another dimension? Can you imagine the possibility that there could be a dark matter universe(s) occupying the same space as us?
What is the upper limit on the number of photons (bosons) that can be stacked on top of one another? I'm assuming that it would become a black hole. So why didn't the big bang become a black hole?
Maybe, the small curled up extra dimension isnt actually a dimension at all, but instead, lorentzian wormholes. They cant be seen or interacted with, simply because any energy used to qualify them collapses them?
The universe does have way more dimensions. Try taking a 4' string and tying a ball on one end and spin it around. Then make another one and spin two around at once. Then make two more a spin 4 around and try not to let the strings tangled up. Infinite Hilbert spaces.
If you move around dimensions,It be the plank particles that move around. so It be like a wire the atoms move around? The wire what make up space and time? Pulse ligo show there were no extra dimensions? I alway thought of it like sand small on the bottom bigger as you go up.The smaller pop up from the bottom by stealing energy from the lower levels.If there a level above us it could be what dark energy and dark matter.dark energy be what being what we lose making the lower move up and dark matter the gravity from the higher level. I like to daydream of how space and time mite work probably off i never study string theory just from what i got on shows like yours and others. put them together and watch it in my mind.
Dr. Sutter, in my opinion is a person who was born with the gift of having a high I.Q. He also has the ability to explain difficult scientific questions to the average person who can understand them easily. That is also a gift.
@@woodypigeon No, but I'm not going to continue this conversation because the good professor has a relevant scientific channel. I'm not willing to let this conversation devolve. I was giving you the benefit of the doubt, but now that I see you are playing with me, so long pal.
What do you mean by a small 'dimension'? Because you didn't describe how a dimension as in 3-shape can be 'small'. If we think of dimensions as a direction not a size, then how can the adjective 'small' be applied?
It means that the radius of the circles are of length of plank order. If you travel through one of that dimensions, you'll be at the same point when you walk a distance of a plank length order.
As I answered to a fellow above, you can generalise this kind of compactification. To a 3 dimensional one, you can imagine a box. Then say that opposite faces are the same surfaces, if you climb, you appear from the floor and so on, this is a 3-torus. Maybe it is not clear, but it have three holes! They are innacesible, but you can detect them indirectly using ropes
@@miguelchamorro953 My comment was about getting this said in an otherwise well generalized layman's discussion. I don't think small was as clearly summarized in an otherwise good video on the subject.
Kaluza toyed with a 5 dim spacetime and somehow electromagnetism could be explained by it, yet some inconsistencies and a lack of merits of the theory led to it being dropped.

I think it's the same as calling a male chicken a rooster. The extra dimensions give a place for the math to hide so you can more easily tie seemingly unconnected phenomenon in a larger framework. So nothing like calling a male chicken a rooster. But if you remember that dimensions are set at 90° from all others, you can play with complex numbers which automatically create ratios of the constituent values which for regular intervals, nets you a constant value. Dimensionality is a new perspective, literally.
@@mwaringmlw I wouldn't classify dimensionality as a new perspective, more like fudging the equations. Fudging the equations suggests that there is something outside these equations that science has yet to observed. Somewhat similar to the paradox of information processing systems and matter: which came first, or are they just different sides of the same coin which is this force?
The point of extra dimensions is that when you start constructing string theory you say there's n dimensions. Then, when you do some calculations it appears that n=to certain integer number or the theory is inconsistent. The theory tells you how many dimensions it has to have.
@@miguelchamorro953 Yes, that is another way of fudging. String theory is an attempt of equating oranges to apples and to do that an intermediary number needs to be put in. This intermediary number is not in either equation, and it is a number that string theory inserted. What I am suggesting is that there is some underlying mechanism, undiscovered, that unites the oranges with the apples.

Hello Thank you for the video, is the speed of light is a constant?
