i also spend time thinking about the String theory is a model of
fundamental 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. The phrase is often used as shorthand for
Superstring theory, as well as related theories such as M-theory.
String theorists are attempting to adjust the Standard Model by
removing the assumption in quantum mechanics that particles are
point-like. By removing this assumption and replacing the
point-like particles with strings, it appears that a sensible
quantum theory of gravity naturally emerges. Moreover, string
theory may be able to "unify" the known natural forces
(gravitational, electromagnetic, weak nuclear and strong nuclear)
by describing them with the same set of equations. (See Theory of
everything)
Very few avenues for experimental verification of the theory have
been claimed.[1] With the construction of the Large Hadron Collider
in CERN some scientists hope to produce relevant data. However, it
is generally expected that any theory of quantum gravity would
require much higher energies to probe.
There are different versions of string theory, depending on factors
such as whether or not supersymmetry is incorporated into the
formulation. These versions are thought to be related to each other
as different limits of one theory, coined M-theory. However, there
is a huge number of possible solutions to string theory as it is
currently understood.[2] Thus it has been claimed by some
scientists that string theory may not be falsifiable and may have
no predictive power.[3][4][5][6]
Studies of string theory have revealed that it predicts
higher-dimensional objects called branes. String theory strongly
suggests the existence of ten or eleven (in M-theory[7]) 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.
An important branch of the field is dealing with a conjectured
duality between string theory as a theory of gravity and gauge
theory. It is hoped that research in this direction will lead to
new insights on quantum chromodynamics, the fundamental theory of
strong nuclear force. This direction of research has better hopes
to make contact with experiment, compared to string theory as a
quantum theory of gravity,[8][9][10][11] though currently the
alternative, Lattice QCD, is doing a much better job and has
already made contact with experiments at various fields with good
results [12], though the computations are numerical rather than
analytic.
ok..that's all copied and pasted from wikipedia....but i got a huge
paragraph out of it
