Episode notes
Origin and Meaning of 'Big Bang'
- The term 'Big Bang' was coined by Fred Hoyle, an opponent of the theory, yet it stuck in scientific discussion.
- We actually have evidence akin to hearing the 'bang,' via cosmic microwave background sound waves from the early universe.
Early Detection of Cosmic Microwave Background
- Andrew McKellar detected the cosmic microwave background 20 years before Penzias and Wilson.
- His work involved measuring temperatures via molecules in outer space, showing early evidence of the CMB.
Science vs Religion in Origins Debate
- Scientific and religious questions about origins intertwine but have different methods and dogmas.
- Some scientific ideas, including the Big Bang, might function like dogmas and need re-examination as evidence evolves.
