PeeMarc Posted March 26, 2008 Report Share Posted March 26, 2008 How long IS a piece of string? Twice as long as half of if. Obviously. Quote Link to comment Share on other sites More sharing options...
Dr_Mike Posted March 26, 2008 Report Share Posted March 26, 2008 How long IS a piece of string? You know, I am really glad you asked that question, as I believe I know the answer. You see, there are concepts of the theory of the universe, which I am fairly well versed in, that suggest there are litterally "strings" attached and flowing through everything in the universe. Thus the "fabric of time". To prove this theory and make it more based on facts known so far... I would need to begin describing the application of relativistic quantum field theory to the classical electromagnetism of Maxwell, which opens even a new can of worms. The Maxwell equations possess a special local symmetry called gauge invariance whereby the photon field, also called the vector potential, transforms as a formula. This transformation of the formula leaves a field strength action which is beyond the scope of my brief explaination. In that the string and superstring experiments show that all physical observables remain unchanged. In the case of electromagnetism for example, the transformations that leave the actions unchanged form a gauge group known as the unitary group U. Our planet has a tremendous gravity field surrounding it which we now know has a drect coorelation to the center of our milky way! So an understanding of the quantum aspects of gauge invariance in gravity leads to the development of relativistic quantum gauge field theory. Gauge invariance is a powerful symmetry that tames uncontrollable infinities in quantum amplitudes and encodes the rich symmetry structure of conserved charges observed in elementary particle physics. For example the strings emminating from the many black holes in the center of our galaxy are connted directly to every electron in our galaxy! Today, three of the observed forces in Nature have been successfully described and documented as formulas of quantum gauge symmetry, and it turns out that these three forces can be described in terms of unitary groups of different dimensions. Physicists write this combination of gauge groups as SU(3)xSU(2)xU(1), Anyone who watches Discovery of the science channel would know this formula already. There are even T-shirts with this formula for sale at beach resort locations all over the USA. So, to the question how long is a string? about one electron at a time in width and infinite in length, as it eventually returns in an ever changing pattern back to it's origin. For some of the people reading this, perhaps 3 inches? Relative... My string is more than 8 inches... NUFF SAID..... ;-) Quote Link to comment Share on other sites More sharing options...

PeeMarc Posted March 26, 2008 Report Share Posted March 26, 2008 Yes, I read "The Fabric of the Universe" as well. A good read. But... String Theory is neither complete nor conclusive and is still work-in-progress. So dont get too tangled up in it. (interesting though). From Wiki... String theory String theory is an incomplete mathematical approach to theoretical physics, whose building blocks are one-dimensional extended objects called strings, rather than the zero-dimensional point particles that form the basis for the standard model of particle physics. By replacing the point-like particles with strings, an apparently consistent quantum theory of gravity emerges, which has not been achievable under quantum field theory. Usually, the term string theory includes a group of related superstring theories and a few related frameworks such as M-theory, which seeks to unite them all. String theorists have not yet completely described these theories, or determined if or how these theories relate to the physical universe. The elegance and flexibility of the approach, however, and a number of qualitative similarities with more traditional physical models, have led many physicists to suspect that such a connection is possible. In particular, string theory may be a way to "unify" the known natural forces (gravitational, electromagnetic, weak nuclear and strong nuclear) by describing them with the same set of equations, as described in the theory of everything. On the other hand, the models have been criticized for their inability, thus far, to provide any experimentally testable predictions. Work on string theory is made difficult by the very complex mathematics involved, and the large number of forms that the theories can take depending on the arrangement of space and energy. Thus far, string theory strongly suggests the existence of ten or eleven (in M-theory) spacetime dimensions, as opposed to the usual four (three spatial and one temporal) used in relativity theory; however, the theory can describe universes with four effective (observable) spacetime dimensions by a variety of methods. The theories also appear to describe higher-dimensional objects than strings, called branes. Certain types of string theory have also been shown to be equivalent to certain types of more traditional gauge theory, and it is hoped that research in this direction will lead to new insights on quantum chromodynamics, the fundamental theory of the strong nuclear force.
