What is the String theory?

Answer 1

11 dimensional string theory has not produced anything.

It 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.

Answer 2

A super string is a model for an elementary particle.
In the Standard Model, quarks, electrons and the like are considered to be pointlike. This gives
problems at short distances where for instance the electromagnetic force between two of them becomes infinite.

The basic idea of super strings is that the fundamental constituents of matter are strings of a length of order of 10^35 m which vibrate at specific frequencies. However, the simplest string theories give more problems then they solve and consistent theories require more than four dimensions.

Answer 3

I should probably read it actually, I was talking to my friend about this the other day...but that's the general definition you get from Wikipedia. It's really complicated and interesting and I won't answer because the answer here is much more complete:

String theory is a model of fundamental physics whose building blocks are one-dimensional extended objects (strings) rather than the zero-dimensional points (particles) that are the basis of the Standard Model of particle physics. 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 is hoped that string theory will develop into a sensible quantum theory of gravity. Moreover, string theory appears to be able to "unify" the known natural forces (gravitational, electromagnetic, weak and strong) by describing them with the same set of equations.

No experimental verification or falsification of the theory has yet been possible, though the Large Hadron Collider near Geneva, Switzerland may produce relevant data.

Studies of string theory have revealed that it predicts not just strings, but also higher-dimensional objects (branes). String theory strongly suggests the existence of ten or eleven (in M-theory) spacetime dimensions, as opposed to the relativistic four (three spatial and one time).[1]

Answer 4

String theory is an excellent one and has been applied in various fields, for example: while playing guitar u adjust the tightness and length of string in order to produce sounds of different pitches and frequency. This is what string theory is all about.

Answer 5

It's a relatively new theory about how everything in the universe is made. Some call it "the everything theory". Possibly what Einstein was working on right before he died. Strings, clusters of strings and their resonance seem to explain a lot more than just simply atoms and molecules.

Answer 6

the theory that the smallest particles of energy in the universe are small strings, or rings like rubberbands and they all vibrate at their own rates. and that vibration determines what the strings are made up of or what they make themselves into.
