Space-time & General Relativity
- General Relativity
- Equivalence Principle
- Inertial mass = gravitational mass
- “No experiment performed in one place can distinguish a gravitational field from an accelerated reference frame”
- Consequences
- Light “bends” in a gravitational field.
- Gravitational “Red Shift”: Clocks at lower gravitational potential run slower than those at higher gravitational potential.
- Leads to objects like “Black Holes”
-
- The Theory
- Mass causes space-time itself to be curved
- Describe gravity not by a force but by motion of bodies in a curved space
