Episode notes
String Theory Types
- String theory has five formulations: Type 1, Type 2A, Type 2B, Heterotic SO32, and Heterotic E8xE8.
- These theories differ in their string types (open, closed), chirality, and gauge groups.
String Modes
- String modes are described by the Polyakov action, not vibrations.
- The modes decompose into left and right-moving components using light cone coordinates.
Gravitons
- Gravitons are massless, spin-2 particles responsible for gravitation.
- They arise from perturbations in the Einstein field equations.
