[Date Answered] March 17, 1998 [Questioner (age, location)] Jesse (Michigan, USA) [Question] I was wondering about the string theory. What is the basis of this theory? How much is know about it, and is there any evidence? [Answer] 
Within the last 20 years, thestring theory has become the leading theory to describe the fundamental particles and forces in nature. The string theory is based on the premise that at an extremely small scale, particles are actually one dimensional extended objects. All objects such as quarks are made up of these strings. Different objects appear depending on the movement of the string particle. As of yet, there is no evidence for or against this theory, but hopefully soon results from experiments using large particle colliders may confirm or disprove this theory.
