Q6. Explain the key features of the steady-state theory of the universe. Why did it lose prominence over time? (10 M)
Difficulty Level: Medium
Reference: IE
Why the question: Prof Jayant Narlikar, one of India’s best-known scientists, passed away in Pune on Tuesday morning .A cosmologist, Narlikar is best known for developing an alternative to the Big Bang theory of the origin of the universe, in collaboration with his PhD guide Fred Hoyle, who was among the prominent figures of 20th-century astrophysics. Key demand of the question: The answer must explain the main features of the steady-state theory and analyse the scientific reasons, especially observational evidence, that led to its decline in favour of the Big Bang model. Structure of the Answer: Introduction Briefly mention the concept of steady-state theory and its origin in contrast to the Big Bang. Body Mention key features like continuous matter creation, eternal universe, and rejection of singularity. Explain how discovery of CMB, evolving galaxies, and lack of proof for C-field caused decline. Conclusion Note the value of such theories in advancing cosmological science and highlight Jayant Narlikar’s legacy.
