Contribution

It introduces a conceptual framework treating gravity as emergent, addressing features unexplained by traditional theories and linking to quantum spacetime insights.

Findings

Highlights features of gravity that challenge conventional explanations

Provides a new perspective on the classical-quantum connection in gravity

Complementary to previous work on emergent space in cosmology

Abstract

I describe several conceptual aspects of a particular paradigm which treats the field equations of gravity as emergent. These aspects are related to the features of classical gravitational theories which defy explanation within the conventional perspective. The alternative interpretation throws light on these features and could provide better insights into possible description of quantum structure of spacetime. This review complements the discussion in arXiv:1207.0505, which describes space itself as emergent in the cosmological context.
