Basic string theory.?

I would highly recommend the last answer. BRIAN GREENE's\nThe Elegant Universe. Great Book, I read it and it explains a lot in real English. Also check out his other book, which is also a great book on string theory its call "The fabric of the Cosmos"(great title!), a little more complex but highly usefull. Or if you hate to read, then buy the Nova special on string theory, which is hosted by Brian Greene (the author). He is one the lead string theorists. Mabye the next Einstein? (Possibly). I would watch the movie first. Then read the book, you would understand the material better with visuals.

Also depends on your scale. At microscopic scales, a strings length is fractal, and thereby infinite.\n\nJust think of measuring a coastline length at a microscopic scale.

At the moment no one knows.\n\nString theories are one attempts to combine Quantum Mechanics and General Relativity, which is what a unified theory is. Thus far no complete theory and no testable predictions have emerged. Perhaps they will in time, or from some of the alternatives like loop gravity.

11 dimensional string theory has not produced anything.\n\nIt is possible that the 7 dimensions that are not perceived are mathematical deception, and therefore string theory is a theory of nothing, as you will find if you read the wikipedia article on string theory.

The question is incomplete.  Which strings?  Components of what?

Another string theory, \nG – hmm, \nwhy not then a G-string theory?\n\n\nCurios question it is. Let us as assume that you will put a geosynchronous satellite at about 300km from the center of the Earth. Since it is a geosynchronous satellite it will stay with the same point on the Earth say over your house.  The air resistance will be minimum as I‘ll assume that the planets atmosphere stays with the planet. Here are some numbers:\n\nEarth rotates at Ve= 1,700 km/hour (diameter ~13,000 km)\nOur geosynchronous satellite Vs= ~40,000 km/hour (at 300,000 km above center of the Earth)\nThis was just to show off, now let us do some serous computation.\n\nAnd the weight of the string say at 1gm/meter will weigh …. will weigh about 126.87 kg by employing the inverse square law of gravity.  (These were very tough computations).\nThat will apply a force of about 1,300 N on that satellite.  Why apply a steady pull? The weight of the string will bring the satellite down.\n\nThe daunting question is how are we are going to attach one end of that string to the satellite in the first place and then getting the other end to your house ;)? Or perhaps…\n\nThanks for all the fish

String theory is a model of fundamental physics whose building blocks are one-dimensional extended objects (strings) rather than the zero-dimensional points (particles) that are the basis of the Standard Model of particle physics. For this reason, string theories are able to avoid problems associated with the presence of pointlike particles in a physical theory. Studies of string theories have revealed that they require not just strings, but also higher-dimensional objects.

you should read more into string theroy and the M theory.  they are both very interesting.  it is hard to wrap your mind around but  this is just one universe that goes along a membrane of universes that goes on infinetely.  the science channel often has show that explin all this much better and they make it pretty easy to understand.

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.

I can't help with Unified Theory, but here's the way a professor explained string theory to me.\n\nImagine that you have a tightrope, and that an elephant is walking on it.  To that elephant, there is only one dimension - the elephant can move forward, and it can move backwards, but it can only move along that straight line.\n\nNow picture that same tightrope, but instead of an elephant, an ant is walking along it.  Like the elephant, the ant can also move forwards and back along the tightrope.  However, the ant can also walk all the way around the tightrope (apparently ants are good at clinging to things while upside-down).  For the ant, there are two possible dimensions - the forward and back one, and the around one.\n\nString theory is basically the idea that there are more dimensions than we realize.  We as humans are the elephant of the previous example - we see only three dimensions, with a potential 4th in terms of time.  According to string theory, there are ants in the world that can access more than these three or four dimensions that we are aware of.  String theorists are currently trying to prove that this is the case.

Superstring theory is an attempt to explain all of the particles and fundamental forces of nature in one theory by modeling them as vibrations of tiny supersymmetric strings. It is considered one of the most promising candidate theories of quantum gravity. Superstring theory is a shorthand for "supersymmetric string theory" because unlike bosonic string theory, it is the version of string theory that incorporates fermions and supersymmetry.\n\nThe deepest problem in theoretical physics is harmonizing the theory of general relativity, which describes gravitation and applies to large-scale structures (stars, galaxies, super clusters), with quantum mechanics which describes the other three fundamental forces acting on the microscopic scale.\n\nThe development of a quantum field theory of a force invariably results in infinite (and therefore useless) probabilities. Physicists have developed mathematical techniques (renormalization) to eliminate these infinities which work for the electromagnetic, strong nuclear and weak nuclear forces, but not gravity. Thus the development of a quantum theory of gravity must come about by different means than were used for the other forces.\n\nThe basic idea is that the fundamental constituents of reality are strings of the Planck length (about 10−35 m) which vibrate at resonant frequencies. The tension of a string (8.9×1042 newtons) is about 1041 times the tension of an average piano string (735 newtons). The graviton (the proposed messenger particle of the gravitational force), for example, is predicted by the theory to be a string with wave amplitude zero. Another key insight provided by the theory is that no measurable differences can be detected between strings that wrap around dimensions smaller than themselves and those that move along larger dimensions (i.e., effects in a dimension of size R equal those whose size is 1/R). Singularities are avoided because the observed consequences of "big crunches" never reach zero size. In fact, should the universe begin a "big crunch" sort of process, string theory dictates that the universe could never be smaller than the size of a string, at which point it would actually begin expanding.

Very simply put, string theory (now most often called "M" theory) is an attempt to unite quantum physics with relativity; we hope that by doing so we can develop a set of equations that will tie together the four fundamental forces of nature. The direct relationship of three of those forces have been linked, but gravity so far remains the "outsider."

Quantum theory accurately describes the way things in the universe behave on small scales.  General relativity does the same for large scales.  However, combining the two theories to find equations that work for things like black holes doesn't really work.\n\nString theory is an attempt to find something that accurately describes interactions on both large and small scales.  Another idea is loop quantum gravity.  Neither idea has really been proven yet, although useful insights have been gleaned from both.\n\nThe hope is that future research at places like the Large Hadron Collider that is scheduled to begin operation soon in Europe will eventually prove string theory correct.  Even if that does happen though, the equations for string theory are actually still too complex for mathematicians to accurately solve them.  Currently, physicists use estimates instead of the true equations.  There will need to be a lot of work done in that area as well before string theory will really replace quantum theory.

Its matter. But what is matter. String theory suggest that all matter is made up of vibrating string and the different vibrations causes different characteristics in matter.

String theory is a physical model whose fundamental building blocks are one-dimensional extended objects (strings) rather than the zero-dimensional points (particles) that were the basis of most earlier physics. For this reason, string theories are able to avoid problems associated with the presence of pointlike particles in a physical theory.\n\nM-theory: M-theory is a cutting-edge theory of physics that deals with the extension of superstring theory. It is somewhat contentious in the physics community, in the absence of experimental backup. If ever experimentally verified, M-theory and string theory would represent remarkable advances in science.

The very best explanation to this is a video I watched in my Philosophy class called "The String Theory" - it is amazing, and makes complete sense. If you looked it up on the internet, it goes into deep detail and is confusing. The video is by Nova (the science channel), and maybe someone else, but it is perfect. Unexplainably mind boggling and amazing.
