The post-determined block universe
Ovidiu Cristinel Stoica
A series of reasons to take quantum unitary evolution seriously and explain the projection of the state vector as unitary and not discontinuous are presented, including some from G…
Revisiting the black hole entropy and the information paradox
Ovidiu Cristinel Stoica
The black hole information paradox and the black hole entropy are currently extensively researched. The consensus about the solution of the information paradox is not yet reached,…
Kaluza theory with zero-length extra dimensions
Ovidiu Cristinel Stoica
A new approach to the Kaluza theory and its relation to the gauge theory is presented. Two degenerate metrics on the -dimensional total manifold are used, one corresponding to…
The geometry of singularities and the black hole information paradox
Ovidiu Cristinel Stoica
The information loss occurs in an evaporating black hole only if the time evolution ends at the singularity. But as we shall see, the black hole solutions admit analytical extensio…
Causal Structure and Spacetime Singularities
Ovidiu Cristinel Stoica
In General Relativity the metric can be recovered from the structure of the lightcones and a measure giving the volume element. Since the causal structure seems to be simpler than…
Spacetime causal structure and dimension from horismotic relation
Ovidiu Cristinel Stoica
A reflexive relation on a set can be a starting point in defining the causal structure of a spacetime in General Relativity and other relativistic theories of gravity. If we identi…
Gauge theory at singularities
Ovidiu Cristinel Stoica
Building on author's previous results in singular semi-Riemannian geometry and singular general relativity, the behavior of gauge theory at singularities is analyzed. The usual for…
The Geometry of Black Hole singularities
Ovidiu Cristinel Stoica
Recent results show that important singularities in General Relativity can be naturally described in terms of finite and invariant canonical geometric objects. Consequently, one ca…
Singular General Relativity
Ovidiu Cristinel Stoica
This work presents the foundations of Singular Semi-Riemannian Geometry and Singular General Relativity, based on the author's research. An extension of differential geometry and o…
An Exploration of the Singularities in General Relativity
Ovidiu Cristinel Stoica
Seminar held at JINR, Dubna, May 15, 2012. In General Relativity, spacetime singularities raise a number of problems, both mathematical and physical. One can identify a class of si…
Metric dimensional reduction at singularities with implications to Quantum Gravity
Ovidiu Cristinel Stoica
A series of old and recent theoretical observations suggests that the quantization of gravity would be feasible, and some problems of Quantum Field Theory would go away if, somehow…
Einstein equation at singularities
Ovidiu-Cristinel Stoica
Einstein's equation is rewritten in an equivalent form, which remains valid at the singularities in some major cases. These cases include the Schwarzschild singularity, the Friedma…
Kerr-Newman Solutions with Analytic Singularity and no Closed Timelike Curves
Ovidiu-Cristinel Stoica
It is shown that the Kerr-Newman solution, representing charged and rotating stationary black holes, admits analytic extension at the singularity. This extension is obtained by usi…
