String Theory

Could someone please explain to me what the string theory is? Please use simple language! I find it hard to understand what you guys say at times (but in the other hand, i learn something new).

the fundamental particle physics theory is that there is like 30+, i (can't remember exact number, but include 4 force particles and half are antiparticles). Each exists at "point" particle.

However there is no explanation for why there exists so many.

 

Now string theory exists to explain this idea amongst other relations in QM and AP. The idea is that they look deeper into this so called "point" structure and say that no its not a point structure but rather a fundamental "string"(closed string) structure. The term fundamental is important because this means that there is no structure smaller and the string cannot break up(which I think is a load of crock). With in this string structure there exists 7+ dimensions (i'm not sure what N-D number their up to now) along with the standard 3 +"1".

 

NOTE: to date this theory is still a mathematical tool but has made some pretty neat experimental links between(sorry I don't have references at hand) QM and AP. Why is it mathematical? there is no equipment currently that could actually see at the scale of the string size.

ok. I get the brief idea. What is AP and QM?

astrophysic..quantum...

sorry it shouhld be relativity and quantum.

but AP holds alot of relativity concepts

Oh I forgot to mention how it explains the fundamental particle:

 

you have a "closed loop" and these closed loops resonate or oscillate at different frequency and have different number of folds therefore you get the different particles.

Go check out the book The Elegant Universe. you will have a total idea about what is string theory, theory of everything.
