Is the bosonic string theory one of the 5 theory included in the M-theory?
157131
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.

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

If M-theory is correct, the Big Bang may have been caused by a collision between other universes so you may find other universes (perhaps with differing physics to our own) beyond our universe. Otherwise you would find nothing.

Because a 1 dimensional string solves many of the problems associated with 0 dimensional point particles of the Standard Model.\n\nGuys, M-Theory isn't different from string theory, it just combines all the string theories into one.  There are actually many string theories and superstring theories.....

Besides the classic standard model of quantum mechanics, there's the superspace version where all possibilities happen in alternate universes.  Then there's string theory and its higher dimensional cousin m-theory.  As far as I know, that last is most current.  Recent Nobel prize for it at Institute of Theoretical Physics at UC Santa Barbara.  But see link as well.

No scientists or astronomers SAY that there is a 5th dimension. There is no direct, observable evidence that such a dimension actually does exist. Dimensions beyond the four we know of are only IMPLIED by certain solutions to mathematical equations used in what's known as string theory. String theory actually implies that there may be as many as 11 dimensions!

"M" Theory is one current attempt at a Grand Unification Theory which reconciles the differences between Quantum Mechanics and General Relativity.  It is impossible to predict what applications could come from such a theory; it would certainly allow us to explain many, many things about our physical world that we do not understand now.  Such a theory may be a long way off, however.

Because "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.\n\nInterest in string theory is driven largely by the hope that it will prove to be a theory of everything. 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.

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.

No, but some physicists think they have.  String theory is the most popular unifying theory, but it makes no testable predictions, meaning that its really more philosophy than hard science.  There are other theories out there too.  For example , Heim Theory involves extra dimensions in which the speed of light is different in order to unify the four fources (electromagnetic, strong, weak, gravity).

Not to beat a dead horse, but it's Edward Witten.  The reason why though is because he was able to unify the several flavors of string theory into, one mathematically stable, unifying theory.  It suggests some pretty "out there" ideas, and its called M Theory.\n\nAlso, I noticed that somebody suggested that it took several scientists to match the power of Einstein's intellect.  However, Einstein did very little to establish laws for the very small, which was governed by Quantum Mechanics, a theory that he very much disliked.  Yet Quantum Mechanics has accurately described the very small for years over years.  So I wouldn't call Einstein irreplaceable.

M-Theory\n\nThere are an infinite number of alternate realities which are integrating. Space-time distortions are occuring. For those who are clear, the observation and experience of these happenings is breathtaking. For others who are experiencing 'blindly' - to be 'out of phase' will cause confusion and fear.\n\nM-Theory unites the 5 superstring theories. According to M-Theory there are 11 spacial dimensions that exist in parallel with our physical reality. That goes along with the theory of 12 or 12 around 1 yet M-theory is not complete as all expands in reality and consciousness.\n\n      M-theory (sometimes also called U-theory) is a theory of physics, which is believed to incorporate and generalize the various superstring theories. Edward Witten proposed the existence of this physical model at a conference at USC in 1995, explaining a number of previously observed dualities and sparking a flurry of new research in string theory.\n\n      What does M stand for?\n\n      When Witten named M-theory, he did not specify what the "M" stood for, presumably because he did not feel he had the right to name a theory which he had not been able to fully describe. According to Witten himself, "'M' stands for 'Magic,' 'Mystery' or 'Membrane,' depending on your taste." Also suggested, has been 'Matrix' and 'Mother of all theories'. Cynics have noted that the M might be an upside down "W", standing for Witten. Others have suggested that for now, the "M" in M-theory should stand for Missing or Murky.\n\n      The name M-theory is slightly ambiguous. It can be used to refer to both the particular eleven-dimensional theory which Witten first proposed, or it can be used to refer to a kind of Uber theory which looks in various limits like the various string theories. Ashoke Sen has suggested that more general theory could go by the name U-theory, which might stand for Ur, or Uber, or Ultimate, or Underlying, or perhaps Unified. (It might also stand for U-duality, which is both a reference to Sen's own work and a kind of particle physics pun.) M-theory in the following descriptions refers to the more general theory, and will be specified when used in its more limited sense.\n\nIf you recall, I have written that the 'M' and the 'W' reverse at the end of time. Some see it as Man and Woman. They will rotate 180 [9] degrees - a 'U'. The 'M' and the 'W' can also be brought together - their ends meeting - then rotated 90 [9] degrees to form an hourglass. The possibilities are endless and will be studied until the end of time.\n\n      M-theory is not complete. It can be applied in many situations (usually by exploiting string theoretic dualities), but the full theory is not yet known. The theory of electromagnetism was also in such a state in the mid-19th century. There were separate theories for electricity and magnetism, and although they were known to be related, it was not clear until Maxwell published his equations just what the relationship was. Witten has suggested that a general formulation will probably require the development of new mathematical language.\n\n      It was shown in the early 1990s that the various superstring theories were related by dualities, which allowed physicists to relate the description of an object in one string theory to the description of a different object in another theory. These relationships imply that each of the string theories is a different aspect of a single underlying theory, which has been named "M-theory".\n\n      More from Wikipedia \n\nM-Theory was the underlying theme in the film, What the Bleep!\n\nM-Theory by George Minaya\n\nThe merging of dimensions integrates your consciousness and expands your awareness to the next level of understanding which will be followed by the merging of your soul aspects with other realities in which it experien

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.

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.

I am assuming this question comes from some thought on the 10-11 dimensions needed by string theory. In this occasion these dimensions are not noticable and have been added because they are needed to make the equations work. In three dimensions and time you only have four variables to work with. But now many physicists have noticed that if you increase our dimennsions to 7,8,9,10,11 it gives more mathematical flexibility and enables us to make equations that can unify gravity with the quantum world. Now for what is the seventh dimension, the first three dimensions are the normal spacial dimensions, up/down, right/left, forward/back. There is also a time dimension sometimes noted as the fourth. Then string theory says there should be another 7 dimensions. Where these would be and why we cant see them is still up for debate but current though is that they are extremely small crumpled up dimensions that we cant notice because there small size makes them have a minimal effect on forces and measurements. I would reccomend reading David Greene's books if you are still intersted in the ideas of string theory and such.
