Hoyle–Narlikar Theory of Gravity: Important for UPSC and Competitive Exams
Introduction
Renowned Indian scientist and science writer Dr. Jayant Vishnu Narlikar recently passed away in Pune at the age of 87. He was known for making science accessible in simple language. In 1960, Dr. Narlikar, along with British scientist Fred Hoyle, proposed the “Hoyle–Narlikar Theory of Gravity,” which differed from Einstein’s Theory of Relativity and brought a new perspective to cosmology.
What is the Hoyle–Narlikar Theory?
Basis: This theory is based on ‘Mach’s Principle’.
Key Ideas:
The mass and motion of every object in the universe are influenced by all other objects.
No object can exist in isolation; its state and motion depend on other objects in the universe.
Difference from Einstein’s Theory of Relativity:
Einstein’s theory describes gravity as the curvature of space-time.
The Hoyle–Narlikar theory emphasizes the mutual influence of all objects in the universe.
The Concept of C-Field:
As the universe expands, new hydrogen atoms are continuously created to fill the empty spaces.
To explain this, Dr. Narlikar introduced the concept of the ‘C-Field’ (Creation Field).
