Study Notes
Steady State Theory
- Proposed by astronomers Fred Hoyle, Thomas Gold, and Hermann Bondi in the 1940s.
- Suggests that the universe is eternal and expanding, maintaining a constant average density by the continuous creation of matter.
Discrediting the Theory
- Largely discredited due to the discovery of cosmic microwave background radiation, which supports the Big Bang Theory instead.
- Observations of distant galaxies and their redshifts provide evidence for the universe's expansion from a hot, dense state.
Contribution of Sir Fred Hoyle
- Instrumental in the development of the theory of nucleosynthesis, which explains the formation of new atomic nuclei in stars.
- Coined the term "Big Bang" ironically while discussing his steady state ideas, emphasizing the contrast between the two theories.
Nucleosynthesis
- Refers to the process by which new elements are formed from nuclear reactions, primarily occurring in stars.
- Involves both primordial nucleosynthesis (formation of elements shortly after the Big Bang) and stellar nucleosynthesis (creation of heavier elements within stars during their life cycles).
