String Theory

ive heard alot about this, but i cant find any straight forward infomation on it!

so would anyone mind explaining what 'String Theory' is, i just want to know the overview of it! thanks

I don't know too much about it, but according to string theorists everything is made of tiny strings instead of particles. You probably knew that much anyway though

lol not really!!! so if particles 'dont' exist, what are these strings and what do theorists say that they are made out off???

It's just a theory, it might not be true, and I'm not sure what they're made of.

Also, since strings are (if they do, in fact, exist) so small, it's impossible to detect them with any currently existing equipment. Until something that can detect them is invented, we have know way of knowing if string theory is correct.

here, I am pretty sure this is all you need http://en.wikipedia.org/wiki/String_theory
Use wiki. Love Wiki. Marry Wiki; the most recourcefull source on the net.

String Theory is, essentially, the idea that everything is made up of strings that behave a certain way. However, it is impossible to prove this theory correct, so it's slowly being rejected by most physicists until a test can be found.

String theory isn't so much being regected as it is sharing the spotlight with other fundamentalist theories, all of which can never be proven, but help explain and unify theories in Relativity and Quantum that have been widely accepted for many years, but have never untill recently worked together. String theory is an integral part of M-Theory, which is a very popular modern theory.

Superstring theory (string theory for short) is the idea that all quarks, leptons and bosons (which acording to current theories are the smallest bits of matter possible) are made up of identical string-things that vibrate diferently to define themselves. Also, acording to string theory, the universe has 10 dimentions. M-Theory adds another, for a total of 11 dimentions.

Although dated a bit (everything in science is dated to tell the truth), The Fabric of the Cosmos is an excelent read if you want to learn more about modern unifying theories in physics. It's far from a light read, but it's not too technical either.

Note: In modern physics, there is a general understanding that very little can actually be "proven". Almost everything that can be observed or experienced has already been explained by Newtonian Classical Physics. Only things at extremes of certain spectrums (like extremely big or extremely small stuff) breaks these rules, and so these theories exist to explain them. Relativity has been somewhat proven, but a lot of Quantum theories that are treated as canon have not actually been proven at all, they just work.
