has anyone here ever heard of the string theory, and if u hav, wat do u think about it?

i string theory is just cool as it integrated all the basic forces of nature and is attempt to bring everything in physics under 1 theory. but like all theories, it has its draw backs.

Bosonic string theory was the first version of string theory. Bosonic string theory, which dealt with string’s vibrational patterns, emerged in the 1970s. This was replaced by supersymmetrical string theory. M-theory in 11 dimensions gives rise to five string theories in 10 dimensions.

Well yes and no, Albert Ensitie composed a theory "The Theory of Unification" that his theory of reltavity and Electro Magatism could co-exist in ont theory this was in the 1930s. Now there might be something Enstine never thought of, tiny string inside quarks that could explain the entire universe in a single equation The Theory Of Everything. Later in the 1940s quantime mech where discorvered. This was much stronger than gravity and in which consists the strong force and the weak force, The strong holds the atom thogther and the weak lets protrons and newtrons attach to is leaving off radition a sit dose so. But every time we try to put Quantime mech and The Theory of reltavity, nothing makes is reasonable. Thats where string theory comes in, that this might link Quantime mech and Reltivity. So no the Theory is not being disproven but proven.

Read Michio Kakuo's book.  He is the "inventor" of strings theory, not Hawking.

it basically says that there are these giant cosmic strings that stretch an infinite distance and they are very dense (as in they're so thin that they are not visible, yet a millimeter would weigh tons and tons) and their huge mass warps space-time and they help to make up the universe as we know it. there are also small vibrating strings on the sub atomic level that make up the smallest divisions of matter. String theory also describes 11 dimentions.  If you're interested in it, read "the elegant universe" by Brian Greene, it explains it a lot better than i can here.

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 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.

String theory is a physical theory that attempts solve several outstanding problems in modern physics.  One problem deals with the unification of the fundamental forces of nature.  Ever since electricity and magnetism were found to be different manifestations of the same force, people have wondered if all the forces of nature are related somehow.  We all know that Einstein's general theory of relativity describes gravity in terms of space-time geometry.  Wouldn't it be great if we could describe all the fundamental force of nature using geometry too.  This is one problem string theory is attempting to solve.  Another problem deals with fundamental particles.  We all know about protons, electrons, and neutrons, but there are also a lot of other particles that don't seem to have much to do with anything.  Why do they exist?  How are they related? Why do they have the physical properties they do?  These are all questions that will hopefully be answered by the string theory.  Lastly, the main reason the string theory was created was to solve a math problem in classical/quantum electrodynamics.  The equations describing the electric field end up with some technical problems that ultimately can be traced to the fact that we are trying to describe pointlike particles.  String theory just gets rid of the pointlike particles and replaces them with strings vibrating in extra dimensions of space-time.

I have heard of the theory before, I wish I could remember the scientists name in the UK who proposed it. Well he may not have the one who proposed it but he was the one featured in the documentay. Its outlandish by most peoples standards, but its a very interesting theory. What I remember most about this gentleman is that he is so paranoid about what could he happening in parallel worlds with his own self that he is terrified to leave his house.....it has to do with every single thing we do affecting our parallel lives in other dimensions and realities.\n\nI would suggest looking it up on www.coasttocoastam.com George Nori and Art Bell touch on stuff like this all the time and have a lot of interesting guests that discuss it.\n\nI first read about parallel lives in a book by Dick Sutphen called "Unseen Influences". This book touches on how every thing affects our lives from processed foods to alien abductions and everything in between. You might want to have a look at that too.

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.\n\nThe basic idea is that the fundamental constituents of reality are strings of energy of the Planck length (about 10-35 m) which vibrate at resonant specific frequencies[1]. Another key claim of 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., physical processes in a dimension of size R match those in a dimension of size 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.

String theory is a step in the direction for the GUT.  But string theory itself is out the window.  GUT will mostly likely be a hybrid of string and quantum.  Each answer some of the most important fundamental questions, but not the same ones and not all of them.  Essentially string theory just states matter is made up of vibrating strings of energy.  For a good book on the subject, three roads to quantum gravity by smolin is excellent.  He is partial to quantum theory but gives both justice and goes a little into some radical ideas that don't branch from either quantum or relativity.

It is a possible solution of the quantum gravity problem, and in addition to gravity it can naturally describe interactions similar to electromagnetism and the other forces of nature. Superstring theories include fermions, the building blocks of matter, and incorporate supersymmetry. It is not yet known whether string theory will be able to describe a universe with the precise collection of forces and matter that is observed, nor how much freedom to choose those details that the theory will allow. String theory as a whole has not yet made falsifiable predictions that would allow it to be experimentally tested, though various special corners of the theory are accessible to planned observations and experiments. Hence critics of string theory occasionally remark that the theory "... is not even wrong," quoting a quip attributed to Wolfgang Pauli.\n\nWork on string theory has led to advances in mathematics, mainly in algebraic geometry. String theory has also led to other theories, supersymmetric gauge theories, which will be tested at the new Large Hadron Collider experiment.

According to string theory, the strings are the universe's \nelemental material. They vibrate in different ways and can\njoin and break apart to form different elemental particles\nthat make up the universe. The strings exist in 11\ndimensions: time, which physicists consider a dimension, and\n10 spatial dimensions. Four of those dimensions are the ones\nwe are familiar with, three spatial dimensions plus time.\nThe other dimensions may be so small they're invisible to\ncurrent detection equipment and are only known to exist because they leave a "footprint" of where they have been.

Nope - String theory was created as a way to make the laws of the universe apply in all situations.  Without string theory, we use one set of laws for sub-atomic particles and another set for everything larger.  Because laws of the universe need to be true everywhere for them to really be "laws," string theory was developed as a way for everything to be governed by one set - the laws remain constant no matter what level you are looking at.

Life would remain simpler with no strings attached.  However, string theory deals with a universe with more that the dimensions we know day-to-day.  For example, you can calculate the diagonal of a square or a cube and the result has physical significance you can deal with.  The forth demension is time but what is meant by the diagonal of that figure no longer a plane or a solid?  What do we know of even greater dimensions, especially if they describe the very small that we can never see?  Certain of the equations that have been produced have enoumous numbers of solutions and it is difficult to find the correct solution and how to test it.  And that is only scratching the surface of a subject that has attracted some of the best brainpower on the globe.  Good luck.
