Study Notes
Hubble's Discovery
- Hubble used spectrographs to measure the speeds of celestial objects
Cosmic Microwave Background Radiation
- Arno Penzias and Robert Wilson initially thought the 'noise' they discovered was radio interference from pigeon droppings on their antenna
- Hubble's discovery of the speeds of celestial objects led to the understanding of the expanding universe
- Penzias and Wilson eventually recognized the 'noise' as the cosmic microwave background radiation, evidence of the Big Bang Theory
- Hubble's discovery led some to consider the Big Bang Theory as a possible explanation for the origin of the universe
