Relativistic Gravity: Light Bending

• basic idea
• The first test: bending of starlight by the Sun; reaction at the time here and here
• gravitational redshift experimenally confirmed: Pound & Rebka (1960)
• Examples of gravitational lensing
  • source-lens-observer aligned: Einstein rings
  • misaligned: Einstein cross
