Introduction
Last time: General Relativity
- Gravitational mass and inertial mass
- Equivalence Principle: the basis of General Relativity
- No need for gravitational forces!
- Examples:
- Bending of light in gravitational field
- Gravitational red shift
Today: General Relativity - continued
- The consequence - Curved space-time
- Examples:
- Free fall according to Galileo and Newton
- Free fall according to Einstein
- Success for Einstein’s theory of Gravity - Unification of theory of space, time, energy, mass, gravity!
- But no one been able to extend this kind of theory to other forces ! Still active area of research in physics!
