Strings

Man, string theory is awesome! 26 dimensions, are they kidding, are they making it us, or even scarier, are they telling the truth? When I first heard about string theory, I said to myself, "its probably just like the atom in that they thought it was the smallest particle possible, but in reality it is not, it is composed of many different indescribable neutrons and electrons and has quarks and positrons. Strings are probably the same way, they are MADE of SOMETHING." According to Brian Greene, author of "The Elegant Universe", scientists look at strings like this; a paragraph is made of sentences, sentences are made of words, words are made of letters, but what are letters made of...mu (the eastern term for not yes and not no), it is a irrelevant question because letters are not made of anything, they just are. I think only some scientists think that and others believe they are made of something, the fabric of being. Crazy.
Back to the 26 dimensions...we know 4 dimensions...height, lenght, width, and time. These 4 most likely travel out into the universe forever, or maybe meet their beginning at the end of the universe. The other theoretical dimensions are probably like a calabi yau shape, which is absolutely insane. This thing wraps into itself like an M.C. Esher painting on acid.
Anyway, the Elegant Universe is a great read, makes even the hardest physics understandable with pictures and metaphors. If you want more, go to http://www.superstringtheory.com/
