Well, we could say that the elementary particles are a very important part of the string theory… However, if you don’t understand a thing about what the previous words tried to convey, you should know you are in the 21st century; take some time to feed your mind. This is the official String Theory website, a corpus of postulations that aim to predict some physical happenings that will take place on this world. If you have never heard about this theory, you should take a tour through the different sections you will see at the homepage, particularly the Basics section. The string theory starts with Newton, who invented calculus to describe the motions of falling objects and orbiting planets, passing through relativity, elementary particles, gravity, and other physical concepts. At this site you’ll find out everything about it and the experiments that are being carried on. String Theory is also about black holes, cosmology, mathematics, and several unresolved matters of this universe.
