I describe the conceptual and mathematical basis of an approach which describes gravity as an emergent phenomenon. Combining principle of equivalence and principle of general covariance with known properties of local Rindler horizons, perceived by observers accelerated with respect to local inertial frames, one can prove that the field equations describing gravity in any diffeomorphism invariant theory can be given a thermodynamic re-interpretation. This fact, in turn, leads us to the…

Lessons from Classical Gravity about the Quantum Structure of Spacetime
I present the theoretical evidence which suggests that gravity is an emergent phenomenon like gas dynamics or elasticity with the gravitational field equations having the same status as, say, the
Thermodynamical Aspects of Gravity: New insights
The fact that one can associate thermodynamic properties with horizons brings together principles of quantum theory, gravitation and thermodynamics and possibly offers a window to the nature of
Equipartition of energy in the horizon degrees of freedom and the emergence of gravity
It is possible to provide a physical interpretation for the field equations of gravity based on a thermodynamical perspective. The virtual degrees of freedom associated with the horizons, as
Thermal nature of a generic null surface
Dynamical properties of a generic null surface are known to have a thermodynamic interpretation. Such an interpretation is completely based on an analogy between the usual law of thermodynamics and
Theoretical Investigations into the Fundamental Understanding of the Nature of Time, Gravity and Dynamics
The origins of dynamics, the physical basis of time asymmetry and the nature of gravity are all considered in the model discussed in this paper. The theory takes entropy as not a sheer thermodynamic
What if ... General Relativity is not the theory
The nature of gravity is fundamental to understand the scaffolding of the Universe and its evolution. Einstein's general theory of relativity has been scrutinized for over ninety five years and shown
What can Classical Gravity tell us about Quantum Structure of Spacetime
Several features of classical gravity, combined with the existence of Davies-Unruh temperature of horizons, support the following paradigm: Gravitational field equations in a wide class of theories,
Relativistic Bose?Einstein condensates: a new system for analogue models of gravity
In this paper we propose to apply the analogy between gravity and condensed matter physics to relativistic Bose?Einstein condensates (RBECs), i.e. condensates composed by relativistic constituents.
Surface Density of Spacetime Degrees of Freedom from Equipartition Law in theories of Gravity
I show that the principle of equipartition, applied to area elements of a surface ∂V which are in equilibrium at the local Davies-Unruh temperature, allows one to determine the surface number density
Entropy density of spacetime and the Navier-Stokes fluid dynamics of null surfaces
It has been known for several decades that Einstein's field equations, when projected onto a null surface, exhibit a structure very similar to the nonrelativistic Navier-Stokes equation. I show that


Entropy density of spacetime and thermodynamic interpretation of field equations of gravity in any diffeomorphism invariant theory
I argue that the field equations of any theory of gravity which is diffeomorphism invariant must be expressible as a thermodynamic identity, TdS=dE around any event in the spacetime. This fact can be
Role of Horizons in Semiclassical Gravity: Entropy and the Area Spectrum
In any space-time, it is possible to have a family of observers who have access to only part of the space-time manifold, because of the existence of a horizon. We demand that physical theories in a
Emergent/quantum gravity: macro/micro structures of spacetime
Emergent gravity views spacetime as an entity emergent from a more complete theory of interacting fundamental constituents valid at much finer resolution or higher energies, usually assumed to be
Friedmann equations and thermodynamics of apparent horizons.
It is shown that the first law of thermodynamics of the apparent horizon dE=T (A)dS(A) can be derived from the Friedmann equation in various theories of gravity, including the Einstein, Lovelock, nonlinear, and scalar-tensor theories.
Is gravitational entropy quantized
In Einstein's gravity, the entropy of horizons is proportional to their area. Several arguments given in the literature suggest that, in this context, both area and entropy should be quantized with
The generalized second law of thermodynamics in generalized gravity theories
We investigate the generalized second law of thermodynamics (GSL) in generalized theories of gravity. We examine the total entropy evolution with time including the horizon entropy, the
