Structural Aspects Of Gravitational Dynamics And The Emergent   Perspective Of Gravity
  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.
