### UNIVERSE IN A BLACK HOLE IN EINSTEIN–CARTAN GRAVITY

- Physics
- 2016

The conservation law for the angular momentum in curved spacetime, consistent with relativistic quantum mechanics, requires that the antisymmetric part of the affine connection (torsion tensor) is a…

### Introductory Chapter: Black Holes, The Singularity Problem, and The Universe

- PhysicsNew Ideas Concerning Black Holes and the Universe
- 2020

Black holes are arguably the most fascinating and mysterious objects in the known universe. Our fascination is heightened by the recent imaging, for the first time, of the event horizon of a galactic…

### The universe as a closed anisotropic universe born in a black hole.

- Physics
- 2020

We consider a universe formed in a black hole in the Einstein--Cartan theory of gravity. The interior of a Schwarzschild black hole can be represented by the Kantowski--Sachs metric that describes a…

### Kruskal–Penrose Formalism for Lightlike Thin-Shell Wormholes

- Physics
- 2015

The original formulation of the “Einstein–Rosen bridge” in the classic paper of Einstein and Rosen (1935) is historically the first example of a static spherically-symmetric wormhole solution. It is…

### A nonsingular, anisotropic universe in a black hole with torsion and particle production

- PhysicsGeneral Relativity and Gravitation
- 2021

We consider a universe formed in a black hole in general relativity with spin and torsion. The interior of a Schwarzschild black hole can be represented by the Kantowski–Sachs metric that describes a…

### Einstein-Rosen "Bridge" Revisited and Lightlike Thin-Shell Wormholes

- Physics
- 2016

We study in some detail the properties of the mathematically correct formulation of the classical Einstein-Rosen "bridge" as proposed in the original 1935 paper, which was shown in a series of…

### Passing the Einstein-Rosen bridge

- Physics
- 2014

A test particle moving along geodesic line in a spacetime has three physical propagating degrees of freedom and one unphysical gauge degree. We relax the requirement of geodesic completeness of a…

### Gravitational Collapse of a Fluid with Torsion into a Universe in a Black Hole

- PhysicsJournal of Experimental and Theoretical Physics
- 2020

We consider gravitational collapse of a spherically symmetric sphere of a fluid with spin and torsion into a black hole. We use the Tolman metric and the Einstein--Cartan field equations with a…

### An Idea to a World inside a Black Hole

- Physics
- 2017

An investigation on black holes reveals interesting new data. Due to the many speculations about the inside of black holes a concept is developed to allow consideration of the properties occuring…

### Shock-wave cosmology inside a black hole

- PhysicsProceedings of the National Academy of Sciences of the United States of America
- 2003

These shock-wave solutions indicate a cosmological model in which the big bang arises from a localized explosion occurring inside the black hole of an asymptotically flat Schwarzschild spacetime.

### Black holes as possible sources of closed and semiclosed worlds.

- PhysicsPhysical review. D, Particles and fields
- 1990

It is shown that instead of the singularity the closed world can be formed inside the black hole and it is argued that this property of this model may also be valid in a more general case provided the gravitation theory is asymptotically free and the limiting curvature exists.

### The observable universe inside a black hole

- Physics
- 1994

A Schwarzschild radial coordinate R is presented for the Friedmann dust‐filled cosmology models. It is shown that a worldline of constant Schwarzschild radial coordinate in the dust‐filled universe…

### The Universe as a Black Hole

- PhysicsNature
- 1972

SINCE Einstein applied his general theory of relativity to study the structure of the universe as a whole1, cosmologists have wondered if the universe is geometrically closed or open. Neither theory…

### Wormholes in spacetime and their use for interstellar travel: A tool for teaching general relativity

- Physics
- 1988

Rapid interstellar travel by means of spacetime wormholes is described in a way that is useful for teaching elementary general relativity. The description touches base with Carl Sagan’s novel…

### The Particle Problem in the General Theory of Relativity

- Physics
- 1935

The writers investigate the possibility of an atomistic theory of matter and electricity which, while excluding singularities of the field, makes use of no other variables than the g&„of the general…

### Past-Future Asymmetry of the Gravitational Field of a Point Particle

- Physics
- 1958

The analytic extension of the Schwarzschild exterior solution is given in a closed form valid throughout empty space-time and possessing no irregularities except that at the origin. The gravitational…

### Universe generation from black hole interiors

- Physics
- 2001

We point out that scenarios in which the universe is born from the interior of a black hole may not posses many of the problems of the Standard Big-Bang (SBB) model. In particular we demonstrate that…
