anyone not believe in the string theory?

I would say that most physicists are sceptical of string theory, to say the least. many simply dismiss it as irrelevant. The basic problem is that it has given NO predictions that can be tested. None, nada. One person in the department (of physics) here worked on string theory and gave up, saying that it simply doesn't really explain anything.

Actually, the wiki on this one is unusually good (and right, for once):\nhttp://en.wikipedia.org/wiki/Cosmic_string\n\nCosmic strings are sometimes confused with the strings of string theory.  There's considerably more observational evidence for the former than the latter. \n\n(I say they're different things, but every time someone like me says something like that, some party-pooper like Bohr comes along and makes a liar out of us.  There's a chance, in my mind at least, that they could be closely related somehow since, supposing either of the things even exist, they're both topological defects in space.  But, that's pure conjecture on my part).\n\nMichio Kaku of the City College of New York has written on both.  If you're looking for something on string theory, and not cosmic string theory, Barton Zwiebach has written the only introductory book worth reading.  If you really did mean cosmic strings, there are several recent journal publications listed in that wikipedia article (and they're all, for once, actually referreed journals).\n\nAs an aside, I see a lot of people posting on both of these around here as though they were somehow proven fact.  There is almost no observational evidence for cosmic strings, and there is none at all for string theory.  There isn't anything wrong with thinking about things like this -- that's where new answers come from.  It's just that I'd like to see the certainty levels turned down a bit.  In the case of string theory, the theory is in much better shape than it was a few decades ago, but it still has no real central theme, it has no real sharp predictions (like the Higgs-Boson, for example, of the standard model of particle physics), and absolutely no experimental verification or support of any kind.\n\nIt just kind of torques me a little that so many people run around on these boards decrying the theory of evolution as unproven, wild-ass conjecture (when, in fact, the evidence supporting the theory of evolution has been more exhaustively catalogued than it has been for probably any other theory in history), while still others are lauding string theory as something as sure as Maxwell's equations.  String theory is a fun idea, and probably a necessary one, but it isn't a sound idea just yet.

Yes and do not believe in one

there is no way to actually prove this theory so i wouldn't believe it

I've been studying these issues alot more in the past year or two, and I find them incredibly compelling. \n\nWhen you look at the massive size of the universe, to assume that we are alone is, if only mathematically, ignorant to some degree. \n\nThe more I study history and astronomy, the more I think these two topics are combined. \n\nI may sound like some wackjob, but, I think that there is life elsewhere, that they have traveled here, and perhaps have had a hand in certain events in history. \n\nI don't believe in coincidences, and there are entirely too many questions in our past without answers that can be provided which point towards humans. \n\nWho knows - maybe I am a wackjob, but in the big picture, you can never question everything enough. \n\nIts a big, big universe. We all get wrapped up in our tiny lives, in our tiny houses, in our tiny countries, and forget about the stars, the galaxies that are out there. \n\nSome day I believe we'll find the truth, unfortunately I believe that this 'someday' will be thousands, if not hundreds of thousands of years in the future.

Ever since man took an interest in the sciences, from perhaps the time of Aristotle onwards, from time to time great ideas have been put forward. Some of these have seemed initially ludicrous, and turned out to be so. Others, with a little development, have given us a great insight into the way that the world works and enabled us to move on. \nAt a given moment of time, it may appear that what we know is fairly correct and will correct timelessly. However, history has shown that this is not the case. Eventually, perhaps, we will know everything, but right now this is far from the case. \nTake one of the fundamental aspects of physics, for instance. For a long time now people have thought that the matter is made up of tiny, invisible particles; atoms and their sub-components. This is the model we learn and that everyone worked around. \nYet in recent times, this has been challenged, by what is known as string theory - and it now seems that this is a better model, perhaps the more 'correct' one. \nString theory, against the traditional theory of matter, says that matter is caused by the vibrations of a string-like structure. These are the fundamental building blocks of matter. It is a bizarre sounding radical theory at first, but now has much support. \nJust like a violin string when plucked will produce sounds, and different sounds when plucked in different ways, so it is with the universe - with string theory, the fluctuations give rise to matter. On this view, the universe may romantically be described as a symphony. The framework of the vibrating string causes the song that we see around us.

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.

They can't be explained. That's why the aforementioned string theory hasn't met a wide acceptance. There are other difficulties with string theory, but they would take a while to explain.

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.

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.

noop, I dont belive in evolution

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 agree that such an explanation is one possibility.  In fact, my failure to fully comprehend the Big Bang in a purely scientific manner is the only reason why I am an agnostic, and not an athiest.  I feel that I need to allow for the possibility.

Einstein also said tha Quantum Physics was rubbish and it has replaced Einstein with the String and M theory proving what he never could \nEinstein was a genious a big guy but he was not infalleble\n\nBut everybody has predicted many kinds of global disastres\none of them could put out the lights

Yes, we are. That is what the senses are. There are no real things out there, there are just clouds of possibilities. Quantum physicists are finding out the universe is much more complicated and unbelievable than once thought. Our perceptions actually modify reality.. that means there could be a universe out there for every potential choice we make in our lives... it's a mind boggling concept, but people are realizing theres more to this world than meets the eye, so to speak.

No! And I don't believe in that crap myself.

No and neither do you are anyone else.\n\nWhen people try to prove it what they find is that as they tighten up the experiment the ESP disappears which is a common characteristic of things which don't exist.
