- Moving wave source
- Red Shift
- Proves galaxies moving away
- Further = faster & bigger observed ^ wavelength
- Proves galaxies moving away
- Big Bang Theory
- Began small / dense / hot -> explosion -> universe
- Evidence
- CMBR - EM radiation - heat
- Only explanation is BBT
- Red Shift
- Universe expanding outwards
- CMBR - EM radiation - heat
