It is proposed that the event horizon of a black hole is a quantum phase transition of the vacuum of space-time analogous to the liquid-vapor critical point of a bose fluid. The equations of classical general relativity remain valid arbitrarily close to the horizon yet fail there through the divergence of a characteristic coherence length. The integrity of global time, required for conventional quantum mechanics to be defined, is maintained. The metric inside the event horizon is different from… Expand
Although it has been generally believed that classical general relativity is always correct for macroscopic length scales, certain predictions such as event horizons and closed time-like curves areExpand
Quantum-corrected Geometry of Horizon Vicinity
We study the deformation of the horizon-vicinity geometry caused by quantum gravitational effects. Departure from the semi-classical picture is noted, and the fact that the matter part of the actionExpand
Thermal relativity, corrections to black hole entropy, Born’s reciprocal relativity theory, and quantum gravity
Starting with a brief description of Born's Reciprocal Relativity Theory (BRRT), based on a maximal proper-force, maximal speed of light, inertial and non-inertial observers, we derive the $exact$Expand
Horizon as critical phenomenon
A bstractWe show that renormalization group flow can be viewed as a gradual wave function collapse, where a quantum state associated with the action of field theory evolves toward a final state thatExpand
Quantum Space and Thermodynamic Approach to Understanding Cosmic Evolution
We present a thermodynamic approach in modeling the evolution of the universe based on a theory that space consists of energy quanta, the spaceons. From wave-particle duality, they can be treated asExpand
Gravitational wave echoes from macroscopic quantum gravity effects
A bstractNew theoretical approaches developed in the last years predict that macroscopic quantum gravity effects in black holes should lead to modifications of the gravitational wave signals expectedExpand
Building flat space-time from information exchange between quantum fluctuations
Abstract We consider a hypothesis in which classical space-time emerges from information exchange (interactions) between quantum fluctuations in the gravity theory. In this picture, a line elementExpand
Mass of the Photon and Dark Energy-Pressure Relation for its Bose-Einstein Condensate at Rest in de Sitter Universe
I develop an elementary physical picture of dark energy and pressure based on most fundamental principles of quantum mechanics (QM) and general relativity (GR) theories. That derives from a previousExpand
What Are the Atoms of the Space Time
Equations of gravity when projected on space time horizons resemble Navier–Stokes equation of a fluid with a specific equation of state. Taking the view that the horizon fluid possesses some kind ofExpand
Lorentz violation with an invariant minimum speed as foundation of the Gravitational Bose Einstein Condensate of a Dark Energy Star
We aim to search for the connection between the spacetime with an invariant minimum speed so-called Symmetrical Special Relativity (SSR) with Lorentz violation and the Gravitational Bose EinsteinExpand


Observations of GRB 990123 by the Compton Gamma Ray Observatory
GRB 990123 was the first burst from which simultaneous optical, X-ray, and gamma-ray emission was detected; its afterglow has been followed by an extensive set of radio, optical, and X-rayExpand
