Question

What is sting theory?

Answer 1

string theory is a complicated theory. it attempts to change our view of the particle and the dimensions we live in.

traditionally spacetime was thought of as 4 dimensional (length, width, height, time). string theory states that there are 7 other dimensions (previous theories say 10, 11, or 26 total dimensions. this is the current form is string theory, properly called M-theory, that calls for 11 total dimensions). these dimensions are curled up into tiny strings about planck length in diameter, which is 1.61625281 x 10^-35 meters. these strings make up the actual fabric of spacetime, and when they collide they release some energy and spacetime, and create an entirely new universe, from ours, that is completely independent.

string theory also gives a new look at the particle. current physics looks at particles as point particles, a 0 dimensional point. string theory says that particles are small one dimensional strings of energy instead of 0 dimensional points. the frequency of the vibrating string determines the energy, and therefore the particle. strings can join together. for example 2 up quarks and a down quark (both types of quark represented by 2 different frequency levels of the strings) can join together to form a proton, which instead of being 3 points, is now a single string made from 3 others.

that is honestly just the beginning. there are things called D-branes and other branes and open and closed strings determining which particle react with which forces or something. to be honest i havent read up on that part, because it hurt my brain.

Answer 2

well I've never heard of a sting theory, but why don't you try "string theory"

Answer 3

String theory is a still-developing mathematical approach to theoretical physics, whose original building blocks are one-dimensional extended objects called strings. Unlike the point particles in quantum field theories like the standard model of particle physics, strings interact in a way that is almost uniquely specified by mathematical self-consistency, forming an apparently valid quantum theory of gravity.

Since its birth as the dual resonance model which described the strongly interacting hadrons as strings, the term string theory has changed to include any of a group of related superstring theories and larger frameworks such as M-theory, which unite them. One shared property of all these theories is the holographic principle.

String theorists have not yet completely described these theories, nor have they determined if or how these theories relate to the physical universe. The logical coherence of the approach, however, and the fact that string theory can include all older theories of physics, have led many physicists to believe that such a connection is possible. In particular, string theory is the first candidate for the theory of everything, a way to describe all the known natural forces (gravitational, electromagnetic, weak and strong) and matter (quarks and leptons) in a mathematically complete system. On the other hand, many detractors criticise string theory because it has not yet provided experimentally testable predictions.

Like any other quantum theory of gravity, it is widely believed that testing the theory experimentally would be prohibitively expensive, requiring feats of engineering on a solar-system scale. Although string theory, like any other scientific theory, is falsifiable in principle, critics maintain that it is unfalsifiable for the foreseeable future, and so should not be called science.

String theory is of interest to many physicists because of the mathematics involved, and because of the large number of forms that the theories can take. String theory strongly suggests that spacetime has eleven dimensions, as opposed to the usual three space and one time, but the theory can easily describe universes with four observable spacetime dimensions as well.

String theories include objects more general than strings, called branes. These are black-holes charged with a differential form vector potential which has more than one index, a different type of electricity and magnetism where the fundamental objects are extended. By studying certain p-branes and identifying them with D-branes, endpoints for strings, certain types of string theory are shown to be equivalent to certain types of more traditional gauge theory. Research on this equivalence has led to new insights on quantum chromodynamics, the fundamental theory of the strong nuclear force.

Answer 4

It's called the 'string theory'!!!!!

Answer 5

It expresses the possibility of the smallest kind of matter. After you get down to atoms, electrons, and quarks, quarks would be made of "strings". Strings are 1 dimensional lines, and we are still doing much research as to what they are.
