Theoretical basis of superstring theory
1, eleven-dimensional space-time (ten dimensional space plus one-dimensional time)
In order to unify bosons and fermions, scientists predicted such particles. Due to the limitation of experimental conditions, it is difficult for people to find such particles that can prove string theory. As one of the most difficult theories, superstring theory has attracted many theoretical researchers to study it. It is one of theory of everything's candidates and can explain all the forces and even the universe we know.
2. In superstring theory, subatomic particles are regarded as a multidimensional cycle that is excited and vibrates (the 10 dimensional space mentioned at the beginning).
3. Like traditional quantum mechanics, superstring theory regards uncertainty as real randomness.
4. Explain the relationship between chords and three-dimensional space and multi-dimensional space with membrane theory.

Supersymmetry in string theory [edit]
Duality of string theory: the yellow arrow is S- duality, the blue arrow is T- duality, and IIA-type strings and E-type hybrid strings can also have dual connection with M- theory (this duality can also be called U- duality).
String theory is the only method we know that can integrate general relativity and quantum mechanics, but only supersymmetric string theory can avoid the problem of superluminal particles, including fermion vibration modes, and explain the matter particles that make up our world. In order to realize the quantum mechanics of gravity and the great unity of all forces and matter, supersymmetry chord theory goes hand in hand. If string theory is correct, physicists hope that supersymmetry is also correct.
The main types are: I string, IIA string, IIB string, O string (SO(32)) and E string (E8×E8). If duality and supergravity are included, the framework of M theory can be unified. The common duality is T duality, S duality and U duality.
