Our purpose here is to introduce the idea of viewing the spacetime as a macroscopic complex system which, consequently, cannot be directly quantized. It should be thought of as a collection of more fundamental "microscopical" entities (atoms of geometry), much like a solid system, in which an atomic (classical) structure must be first recognized in order to ensure a correct and meaningful quantization procedure. In other words, we claim that the classical limit from a quantum theory of gravity…

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

Emergent spacetime, and a model for unitary gravitational collapse in AdS

We propose a CFT unitary description of the gravitational collapse. The starting point is the model of a black hole in AdS proposed by Maldacena in arXiv: 0106112 [hep-th]. We show that by proposing

NON-BOLTZMANN STATISTICS AS AN ALTERNATIVE TO HOLOGRAPHY

An intriguing question related to black hole thermodynamics is that the entropy of a region shall scale as the area rather than the volume. In this essay we propose that the microscopical degrees of

Einstein-Cartan formulation of Chern-Simons Lorentz-violating gravity

We consider a modification of the standard Einstein theory in four dimensions, alternative to R. Jackiw and S.-Y. Pi, Phys. Rev. D 68, 104012 (2003), since it is based on the first-order

TFD Extension of the Open String Field Theory

We study the application of the rules of Thermo Field Dynamics (TFD) to the covariant formulation of Open String Field Theory (OSFT). We extend the states space and fields according to the

Thermo-Field Extension of Open String Field Theory

We study the implementation of Thermo Field Dynamics (TFD) to the covariant formulation of Open String Field Theory (OSFT). In this paper, we extend the state space and fields according to the

Wormhole solutions to Hořava gravity

W wormhole solutions to Hořava nonrelativistic gravity theory in vacuum are presented and it is shown that, if the parameter A is set to one, traversable wormholes connecting two asymptotically de Sitter or anti-de Sitter regions exist.

Thermofield dynamics extension of the open string field theory

We study the application of the rules of thermofield dynamics (TFD) to the covariant formulation of open-string field theory. We extend the states space and fields according to the duplication rules

The three perspectives on the quantum-gravity problem and their implications for the fate of Lorentz symmetry

Each approach to the quantum-gravity problem originates from expertise in one or another area of theoretical physics. The particle-physics perspective encourages one to attempt to reproduce in

In the membrane paradigm, the stretched horizon will disappear for a freely falling observer which passes the horizon

    the physical meaning of this MGS could also be questioned; however, the notion of macroscopical observer in itself must be clarified in this new context, but we will not do it here
