Introduction to Superstring Theory
Superstring Theory (English: Superstring Theory), which is a kind of string theory, is a kind of string theory that introduces supersymmetry, which refers to the cornerstone of matter is a string in ten-dimensional space-time.
String theory believes that there are no particles, only strings move in space, and different particles are just different vibration modes of strings. All the interactions that occur in nature, all matter and energy, can be explained by the splitting and combining of strings.
