In string theory do string entangle to form the fabric of space?

I believe that space and time are just 4 of the 11 dimensions that the strings exist in, and vibrate in, giving rise to the particles and their properties as we know them.

Basically, the space that you and I experiences daily is 3 dimensions: up/down, left/right, forward/backwards. But space doesn't have to be 3 dimensions. It can be any number of dimensions. Of course, it is very difficult for us 3-dimensional beings to imagine what these dimensions are, or where they are. The problems is that we can NEVER see the fourth spatial dimension, never mind the 5th or the 6th, etc. etc. Let me explain why.\n\nImagine for a moment that we are 2-d beings, not 3-d. And we live on the surface of a sphere (like a ballon). This sphere is our universe. Everything we see, touch and experience happens on the surface of this sphere. We can go left/right and forward/backwards. But we can never go up or down. When we travel in one direction, we will eventually circumnavigate the sphere and make a complete circle, which brings us back to the initial starting point. If we ask the 2-d beings to imagine 3-dimensional space, all we can tell them is that the 3rd dimension (up/down) is orthogonal (a fancy way of saying perpendicular) to the surface of the sphere.\n\nThis is exactly our situation when we talk about the 4th, 5th, 6th, whatever nth dimension. They are defined as the dimension that is orthogonal to the n-1 th space. So the 4th dimension is orthogonal to our 3-dimensional space, and the 5th dimension is orthogonal to the 4-dimensional space, etc. etc.\n\nNow about Super String Theory and these higher dimensions: what the theory predicts is that our universe does indeed have more than 3 spatial dimensions. Some version sof the theory say there are 10, some say there are 11. Whatever the number (it doesn't really matter in our discussion here), these higher spatial dimensions are currently curled up into very very tiny spaces. So what does that mean?\n\nWe now go back to our 2-d being living on a sphere example. For the time being, let's say we are now on a flat 2-dimensional surface (like a sheet of paper). Super String Theory says that the higher dimensions are curled up. So let's consider in our case the 3rd dimension as the curled up dimension. This means that if we were to magnify any point on the 2-d surface all the way to about 10^-35 meters (Planck Length), we will see that there is a tiny loop (like a loose thread on a knitted sweater).\n\nNow imagine if our 2-d being were (1) small enough to see and fit inside the loop, and (2) able now to travel in the 3rd dimension, then for it to go in the up/down direction, the 2-d being will now be just going around in circles inside the loop. Remember in the previous case, our 2-d being can travel in one direction on the surface of the sphere and then return to the same point. Well, here our 2-d being is traversing through the 3rd dimension, except that there is no up and down because the 3rd dimension is "curled up" into a loop. So the 2-d being just goes around the loop in circles.\n\nIf you understood the above, then now we can answer the question, what and where are these higher dimensions in our universe. They are culred up in every point in our 3-dimensional space, and if we were small enough and we could move into these higher dimensions, then we would be moving through these very convoluted curled up loops, but not really able to go anywhere.\n\nBecause these higher dimensions are curled up into such tiny tiny loops (remember 10^-35 meters), only the most elementary structures like "strings" are affected by them. The size of these strings are of course on the order of 10^-35 meters long, and can traverse through the curl up dimensions. When the strings vibrate, the vibrations in the 3 large dimensions don't have any effect, but in the curled up higher dimensions, the vibrations can create resonance like playing a musical note.\n\nThese resonances are the stuff of reality, meaning these vibrational resonances of the strings inside the curled up dimensions is what creates matter and energy and thus everything that&#

Theories such as string theory predict that the space we live in has in fact 10 dimensions, but that the universe measured along these additional dimensions is subatomic in size. As a result, we perceive only the three spatial dimensions that have macroscopic size.

String Theory is only a theory of description of elementary particles based on one-dimensional curves, or "strings," instead of point particles, given by from some theoretical Physicist.\nThe energy-scale at which the stringlike properties would become evident is so high that it is currently unclear how any of the forms of the theory could be tested.\nSo it has not been tested yet and I think it will remain a theory not reality in near future.

Some new ideas in physics posit that there are more than the obvious 3 spatial and 1 temporal dimension. These theories are intended to explain all four fundamental forces in nature (electromagnetism, the strong nuclear force, weak nuclear force and gravity) by serving as a bridge between quantum mechanics and general relativity.\n\nIt turns out that one way that - perhaps - QM and GR can be connected is to postulate some extra dimensions, with an extra 7 spatial dimensions for a total of 11. If such extra dimensions exist they may be too small to interact with our standard 3D+time word.\n\nSo, in this case, a 6th dimension would be one of these smaller extra dimensions.\n\nIt should be noted, though, that thus far string theories are very theoretical, and there is no real physical evidence (yet), nor even a complete theory. Its still very much up in the air.\n\nA nice, simple guide to string theory basics can be found here:

According to string theory, the extra dimensions would be infinitesimally small, so we could not travel into them.  However, there are other theories (i.e. Heim Theory) that have dimensions that we could travel through.

I might be able to answer more fully if you reword your question and put some thought into exactly what it is you're looking for.  For example, string theory predicts extra dimensions beyond the four we experience.  Is that it?  Or are you referring to the Branes explanation, where there are extra dimensions as well as additional universes removed from our own?  Get some additional details and I'll edit.

http://en.wikipedia.org/wiki/String_theory\n\nI know giving a url as an answer is a cop out, but really, it is the best way to explain something as complex as the string theory. READ IT! It's pretty cool!

string theory is realy a piece of genius it came uponly since v found so many irregularities in the quantum gravity theory of einstein and others \n to no the basics u bettter read some god books onthe topic\n           i can only say that by far it is a great piece of work and only if v had better particle acc v could hav proved that the theory is correct (or wrong )\n     also rear about the m-theory if u can

I figure that a theory that predicts 6-7 extra dimentions may be true, but it is really easy to explain things with 9-10 degrees of freedom..\n\nTHink about it, you have data... you try to make a linear fit, most often you don't get a good correlation... Now try a 4th power polynomial fit... you get something better... 11th power can describe any data, but it makes no really valid predictions. \n\nAs Einstein said, "Any fool can make things bigger and more complicated" (don't remember exact words so this is paraphrasing) "but to explain things in simple manner truly takes a genius"\n\nBut there are things about it that are likely true, for instance the "strings" themselves... Yes, everything is made of a fundamental unit of energy (double slit experiment demonstrated that matter is localized energy) \n\nLast point: to have a valid theory it should predict measurable results, string theory does not.\n\nSo no, I doubt its tue, but only time will tell.

first of all 4 dimentions is true because there are 3 spacial dimentions and the 4th is time.\n\nand we dont know if superstring theory is true, it's still just an idea, and hasn't been proven, nor has any evidence been shown for it, we just like it because it can be used to explain certain things if it were true.  in string theory, there are 11 dimentions, its not crap, why dont you read "the elegant universe" by brian greene, or at least do some type of reading on it before you call it crap.  the dimentions are interwoven in our own universe, just like the 4 that are already proven.

String theory.  Two parallel universives touched briefly - creating the big bang.

Additional info: I've talked to Holger Bech, one of the three founding fathers and Danish, and not even he believes in the theory. Basically, this is due to the String Theory postulating the existence of 9 dimensions. We can see that this is pretty far from the case, with there only being 3 physical dimensions and time, equaling 4. Furthermore, S.T. postulates that almost 300 of a specific grouping of particles exist. Experimental testing estimates that only 16 exist.

"Time" is not a dimension in the same sense that x,y,z,a,b,c, ..etc are spatial dimensions.\n\nThough the human mind is cabable of imagining muti-dimensional space, and can create clever matematical concepts supporting the idea, there is not one whit of physical evidence to support it.  And there is ample evidence to refute it.  \n\nTake gravity, for example.  Measurments show that gravity decreases as the inverse square of the distance from the source, exactly as it should in three-dimensional space.  If there were more than three spatial dimensions, that wouldn't be the case.  So if you want to postulate there are more than three dimensions, you've got to explain why gravity ignores them!\n\nAlso, take ElectroMagnetic Radiation (EMR), which also behaves the same way - i.e. it decreases as the inverse square of the distance from the source, just as it should in three dimensional space.  So if you postulate more than three dimensions, you've got to explain why EMR doesn't know about it!\n\nAs to string theory, scientists proposing it can't agree whether it requires twenty-six dimensions in order for the math to come out right, or "just" ten!  And they all admit there's no known way to prove or disprove the theory itself. That's makes the theory pretty weak. In fact, it makes it almost science fiction! Great mind exercise, but no eidence of reality!\n\nEinstein's theories provide predictions that can be proved or disproved. That's one reason they are so powerful.\n\nSo the jury's still out on multi-dimensional space - and pobably will be for some time to come.\n\nBut it's fun to speculate!  Just don't bet your food money on it!

In a word, yes. When the universe was created, all matter was condensed. What we perceive as 'expansion' which is all bodies moving away from each other is just illusion based on the fact that it's the space between them that's expanding. Imagine a balloon that's flat, and you draw 2 marks on it, right beside each other. Once the balloon is inflated, the rubber stretches, causing the space between the marks to widen, but it appears that it's the marks themselves that's moving.\nAs a side note, it's my personal belief that the universe, and everything in it (including you and me) are just figments of our extremely warped and deluded imagination. We are in a dream.

Ok, the parallel universe theory is a theory that some quantum physicists believe. The reason we have no detected them as of yet is because we can only detect forces and our forces would probably not be able to travel between the dimensions. In one version of string theory gravity is able to travel between the universes. If this is true we should be able to measure small fluctuations from the predicted value of gravity. So far they have tested this ont he scale of tenths of centimeters. There has been no evidence yet that there are parallel universes. If we get better equipment and we can measure that gravity does not follow newtons equation that may prove the existence of a parallel universe. I hope that helped

Not exactly Quantum theory, rather String Theory which was developed from from quantum mechanics.
