We consider the radial geodesic motion of a massive particle into a black hole in isotropic coordinates, which represents the exterior region of an Einstein–Rosen bridge (wormhole). The particle enters the interior region, which is regular and physically equivalent to the asymptotically flat exterior of a white hole, and the particle’s proper time extends to infinity. Since the radial motion into a wormhole after passing the event horizon is physically different from the motion into a… Expand

Kruskal–Penrose Formalism for Lightlike Thin-Shell Wormholes
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 isExpand
Universe in a Black Hole in Einstein–cartan Gravity
The conservation law for the angular momentum in curved spacetime requires that the antisymmetric part of the affine connection (the torsion tensor) is a variable in the principle of least action.Expand
A nonsingular, anisotropic universe in a black hole with torsion and particle production
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 aExpand
Einstein-Rosen "Bridge" Revisited and Lightlike Thin-Shell Wormholes
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 ofExpand
Passing the Einstein-Rosen bridge
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 aExpand
Cosmology with torsion: An alternative to cosmic inflation
Abstract We propose a simple scenario which explains why our Universe appears spatially flat, homogeneous and isotropic. We use the Einstein–Cartan–Kibble–Sciama (ECKS) theory of gravity whichExpand
Gravitational Collapse of a Fluid with Torsion into a Universe in a Black Hole
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 aExpand
The Worldline of an Inertial Observer on the Kruskal-Szekeres Coordinate Chart
The (proper) transit time of a light signal emitted by an observer at rest at r_0 in a Schwarzschild gravitational field, reflected by body at some distance r>r_0 and received by the observer isExpand
An Idea to a World inside a Black Hole
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 occuringExpand
A Rotating Black Hole Solution for Shape Dynamics
Shape dynamics is a classical theory of gravity which agrees with general relativity in many important aspects, but which possesses different gauge symmetries and can present some fundamental globalExpand

TLDR
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. Expand
Black holes as possible sources of closed and semiclosed worlds.
TLDR
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. Expand
