The Enigma of Gravity

Abstract

The nature of gravitational interaction remains a mystery in spite of it being probably the most ancient force experienced by humanity. The major paradigm shift in the understanding of gravity came with Einstein's theory of General relativity around 1915. But the fact that principles of General Relativity and those of Quantum Theory do not merge together seamlessly suggests that we probably need yet another paradigm shift. Recent studies show that Gravity could be an emergent phenomenon like, for example, fluid mechanics or elasticity and lead to a very different perspective on the nature of gravity. I will provide a historical overview of how our understanding of Gravity has evoled and describe some of the recent results in this subject.
