Following a short account of the history of the idea of black holes, we present a review of the current status of the search for observational evidence of their existence aimed at an audience of relativists rather than astronomers or astrophysicists. We focus on two different regimes: that of stellar-mass black holes and that of black holes with the masses of galactic nuclei.

It is often claimed that cosmology became a true scientific inquiry with the advent of the General Theory of Relativity. A few subsequent putative observations have been misconstrued in such a way asExpand

In this thesis, aspects of the physics of black holes are reviewed and new results in black hole thermodynamics are presented. First, general black hole solutions of Einstein’s equations of generalExpand

The mathematical theory of Relativity is riddled with violations of the rules of pure mathematics, logical contradictions, and conflict with a vast array of experiments. These flaws are reviewedExpand
Accretion of a Vlasov gas on to a black hole from a sphere of finite radius and the role of angular momentum
The accretion of a spherically symmetric, collisionless kinetic gas cloud on to a Schwarzschild black hole is analysed. Whereas previous studies have treated this problem by specifying boundaryExpand

This article outlines the search for an exact general relativistic description of the exterior (vacuum) gravitational field of a rotating spheroidal black hole surrounded by a realistic axiallyExpand

Recent research on superfluid quantum vacuum as the physical origin of universal space has opened new perspectives in astronomy and cosmology. Every stellar object is in the active relation withExpand
Stationary Black Holes: Uniqueness and Beyond
TLDR
Developments in the subject are reviewed and the uniqueness theorem for the Einstein-Maxwell system is discussed in light of the high degree of symmetry displayed by vacuum and electro-vacuum black-hole spacetimes ceases to exist in self-gravitating non-linear field theories. Expand
A New Look at Relativity
We derived new relativity equations that not only described the related phenomena but also the origin of universe and its general evolution both at the cosmological and quantum scales. We found thatExpand
A Non-anthropic Solution to the Cosmological Constant Problem
Accelerating cosmological expansion is driven by a minuscule vacuum energy density possibly seeking opportunities to decay to a true ground state. Quasar characteristics imply their central enginesExpand
Gravitational waves emitted by a particle rotating around a Schwarzschild black hole: A semiclassical approach
We analyze the gravitational radiation emitted from a particle in circular motion around a Schwarzschild black hole using the framework of quantum eld theory in curved spacetime at tree level. TheExpand
