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 equations of fluid dynamics/elasticity. This paradigm views a wide class of gravitational theories – including Einstein's theory – as describing the thermodynamic limit of the statistical mechanics of 'atoms of spacetime'. Strong internal evidence in favour of such a point of view is presented using… 

Gravity and Spacetime: An Emergent Perspective

Classical general relativity treats spacetime as a continuum just as fluid dynamics treats a fluid as a continuum. Boltzmann was the first to emphasize that the thermal phenomena exhibited by a fluid

Gravity and quantum theory: Domains of conflict and contact

There are two strong clues about the quantum structure of spacetime and the gravitational dynamics, which are almost universally ignored in the conventional approaches to quantize gravity. The first

THE HYDRODYNAMICS OF ATOMS OF SPACETIME: GRAVITATIONAL FIELD EQUATION IS NAVIER–STOKES EQUATION

There is considerable evidence to suggest that field equations of gravity have the same conceptual status as the equations of hydrodynamics or elasticity. We add further support to this paradigm by

Null Surface Geometry and Associated Thermodynamics

The emergent gravity paradigm interprets the gravitational field equations as describing the thermodynamic limit of the underlying statistical mechanics of the microscopic degrees of freedom

Spacetime Geometry as Statistic Ensemble of Strings

Jacobson theorem (Ref. [1]) shows that Einstein gravity may be understood as a thermodynamical equation of state; a microscopic realization of this result is however lacking. In this paper, we

General relativity from a thermodynamic perspective

I show that the gravitational dynamics in a bulk region of space can be connected to a thermodynamic description in the boundary of that region, thereby providing clear physical interpretations of

Thermodynamical interpretation of the geometrical variables associated with null surfaces

The emergent gravity paradigm interprets gravitational field equations as describing the thermodynamic limit of the underlying statistical mechanics of microscopic degrees of freedom of the

Emergent quantum mechanics as a classical, irreversible thermodynamics

We present an explicit correspondence between quantum mechanics and the classical theory of irreversible thermodynamics as developed by Onsager, Prigogine et al. Our correspondence maps irreversible

The Atoms of Space

In this brief note, it will be shown that space may have hidden properties normally attributed to elementary particles, such as mass and charge. We will also elucidate the thermodynamic properties of

Emergent perspective of gravity and dark energy

There is sufficient amount of internal evidence in the nature of gravitational theories to indicate that gravity is an emergent phenomenon like, e.g, elasticity. Such an emergent nature is most

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

GENERAL: Hidden Symmetries for Thermodynamics and Emergence of Relativity

Erik Verlinde recently proposed an idea about the thermodynamic origin of gravity. Though this is a beautiful idea, which may resolve many long standing problems in the theories of gravity, it also

The Einstein equation is derived from the form of black hole entropy together with the fundamental relation $\delta Q=TdS$ connecting heat, entropy, and temperature, and its validity is seen to depend on the existence of local equilibrium conditions.

It was recently suggested that quantum field theory is not fundamental but emerges from the loss of phase space information about matter crossing causal horizons. Possible connections between this

Starting from first principles and general assumptions we present a heuristic argument that shows that Newton’s law of gravitation naturally arises in a theory in which space emerges through a

I show that combining the principle of equivalence and the principle of general covariance with the known properties of local Rindler horizons, perceived by accelerated observers, leads to the

General Relativity as Geometro-Hydrodynamics

In the spirit of Sakharov’s ‘metric elasticity’ proposal [1], we draw a loose analogy between general relativity and the hydrodynamic state of a quantum gas, and examine the various conditions which

Gravity as elasticity of spacetime: a paradigm to understand horizon thermodynamics and cosmological constant

It is very likely that the quantum description of spacetime is quite different from what we perceive at large scales, l≫(Gℏ/c3)1/2. The long wavelength description of spacetime, based on Einstein's

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.
