描述.This thesis explores the connection between gravity and thermodynamics and provides a unification scheme that opens up new directions of exploration. Further elaborating on the Hawking effect and the possibility of singularity avoidance, the author not only discusses the information loss paradox at a broader level but also provides a possible solution to it. As the final frontier, it describes some novel effects arising from the microscopic structure of spacetime.. .Taken as a whole, the thesis addresses three major research areas in gravitational physics: it starts with classical gravity, proceeds to the black hole information loss paradox, and closes with Planck scale physics.  The thesis is written in a lucid and pedagogical style, with an introduction accessible to researchers from other branches of physics and a d.iscussion presenting open questions and future directions, which will benefit and hopefully inspire next-generation researchers..

In this chapter, we show how one may decipher the information about the in-state of the field from such distortions.

Nicolas Durand,Bruno Crémilleuxd entropy. Defining the surface degrees of freedom using Wald entropy and Komar energy density to define the bulk degrees of freedom, we can also show that the time evolution of the geometry is sourced by their difference. If the spacetime admits a timelike Killing vector field the holographic equipartition for Lanczos-Lovelock gravity follows.

Ireneusz Czarnowski,Piotr Jedrzejowiczhich have thermodynamic interpretation. The first one reduces to a Navier-Stokes equation for the transverse drift velocity. The second can be written as a thermodynamic identity, while the third one describes the time evolution of the null surface in terms of suitably defined surface and bulk degrees of freedom.

https://doi.org/10.1007/978-1-4471-0745-3ball, the energy densities of both matter and scalar field diverge near the singularity in both (1+1) and (1+3) spacetime dimensions. Intriguingly the energy density of the field dominates over that of classical matter. These results suggest that the back-reaction effects are significant in the region close to the singularity.
