". . . String Theory is one of the biggest mysteries of science today. Proven it be correct, it could change the whole way we look at the fundamentals of physics. String Theory states that elementary particles are not "point particles", but are tiny strings that have different states of vibration to reflect the type of particle it is."
". . .the theory states that the 4 dimensional (x,y,z, and time) world that we live in is actually a 10 dimensional world and that the extra 6 spacial dimensions are either curled up so small, or expanded so large that we cannot detect them."
