    ACCORDING TO WIKIPEDIA:

    "In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. In string theory, the different types of observed elementary particles arise from the different quantum states of these strings. In addition to the types of particles postulated by the standard model of particle physics, string theory naturally incorporates gravity, and is therefore a candidate for a theory of everything, a self-contained mathematical model that describes all fundamental forces and forms of matter. Aside from this hypothesized role in particle physics, string theory is now widely used as a theoretical tool in physics, and it has shed light on many aspects of quantum field theory and quantum gravity."

    Does STRING THEORY have the potential to explain it all---including the mysteries of gravity?

      I honestly have been saying all these years that Magick exists, and all it is is what science has yet to be able to explain, which is plenty. I think that quantum science will be the explanation of magick, of energy fields, of levitation, and so on.
      I don't know that string theory can explain all that, but I know it's a step closer

        I agree...every step toward more understanding is an important step in the right direction.

      There isn't anyone here who understands string theory that could make any kind of valid opinion.

        I watched a PBS special on it around 5 years ago, so I consider myself somewhat of an expert.

            Ooh, did it sound like I was mocking anyone? I wasn't... just myself. I did watch the special, it was interesting.

        I think several physicists would disagree with your sense that no one understands String Theory. Among them those scientists who, as of 2010, made clear that it was now possible to test String Theory.

        Experiments are being conducted to test what is known as quantum entanglement and to see if String Theory works to predict the behavior of entangled quantum particles.

        Among those who understand and support String Theory:

        Edward Witten
        Leonard Susskind
        Lisa Randall
        Michio Kaku
        Brian Greene

        In addition, first steps in the direction of proof of String Theory was reported in 2012.

          I think he just meant no one on this forum was skilled enough to comment. smile

          Did you actually read my post? I said there wasn't anyone "here", meaning these forums. Of course, there aren't many who understand string theory due to the complex mathematics.

            Why presume that no one here on "Hubpages" understands String Theory or has enough understanding to comment on it?

              Because you aren't the first person here to create a thread on string theory.

              Btw, there are no experiments being conducted on string theory because no one has figured how to test string theory yet.

              I would love to hear your thoughts on it. I like to learn.

                All of the subatomic particles of basic physics are just one fundamental thing: a string. Strings can be open or closed. Closed strings might account for the "what it is" of gravity. Open strings for everything else.

                And these strings oscillate. And when these strings oscillate in unique ways we get an electon, or photon or a quark.  This oscillation makes mathematical sense only when there are multiple---perhaps 11 (or more) dimensions.

                What I like about String Theory:

                It has the potential to unify Newton and Einstein (some Einstein worked for much of his later life to do);

                It enables us to think beyond the visible world and visible/known dimensions of the universe;

                It has the potential to help us to understand IF movement in excess of the speed of light is possible...and that has the potential to change everything and make everything possible---including travel over the vast distances of the universe, and perhaps, time.

                  Not really, it was Einsteins theory of Relativity that showed Newton was wrong, string theory cannot possibly unify them.



                  But, they have already found that faster than light travel can only be achieved within the realm of General Relativity and not String theory.

                    If Newton were "wrong" then rockets would not fly. Newton's theories are not wrong, but limited in that they apply only to things with mass.

                    String Theory suggests a variable speed of light and suggests that particles can faster than the speed of light (which neutrinos can do---though whether consistently or not seems problematic); particles traveling faster than the speed of light negate some (not all) of Einsteins's special theory of relativity.

                    Traveling faster than the speed of light OR the speed of light being variable violates Einstein's theories.

                    So if faster than speed of light travel is possible (and it seems possible for neutrinos) and if the speed of light may be variable (which some scientists suggest is the stuff of "dark matter"), then Einstein needs some reconsideration.

                    Einstein needs reconsideration as did Newton in the advent of Einstein's work.

                  I didn't remember that special I watched mentioning that string theory effected gravity. Surely it must have unless that is a new revelation.

                    Some string theorists think strings may account for gravity.

                    The "how" of that is, however, the subject of much debate.

                    Defining gravity---explaining what it is and how it came to be, eludes science at this point just as it eluded Newton and Einstein.
