ENERGY CONTENTS OF THE WORMHOLES [PDF]

open access: yes, 2011
In this study, energy distributions of the various wormholes which connect two different parts of the universe have been investigated. We have obtained the energies of several types of wormholes as the statical wormholes, wormholes with scalar fields ...

On Possible Origin of an Artificial Wormhole

open access: yesUniverse, 2022
We assume the picture in which a vacuum is filled with virtual wormholes. The presence of external fields changes the distribution of virtual wormholes and, in principle, allows for the creation of a coherent structure that can work as an actual wormhole

New Scenarios of High-Energy Particle Collisions Near Wormholes

open access: yesUniverse, 2020
We suggest two new scenarios of high-energy particle collisions in the background of a wormhole. In scenario 1, the novelty consists of the fact that the effect does not require two particles coming from different mouths.

Traversable Finslerian wormholes supported by phantom energy

open access: yesFrontiers in Physics, 2023
This paper supplements the article (Eur. Phys. J. C 76: 246, 2016) by extending some more new wormhole solutions in the background of Finslerian geometry.

Black Hole and Wormhole Solutions in Einstein–Maxwell Scalar Theory

open access: yesUniverse, 2022
We classified and studied the charged black hole and wormhole solutions in the Einstein–Maxwell system in the presence of a massless, real scalar field.

Closed Timelike Curves, Singularities and Causality: A Survey from Gödel to Chronological Protection

open access: yesUniverse, 2021
I give a historical survey of the discussions about the existence of closed timelike curves in general relativistic models of the universe, opening the physical possibility of time travel in the past, as first recognized by K.

Wormholes in holography [PDF]

open access: yes, 2022
This thesis focuses on wormholes in holography. Wormholes are tunnel geometries that connect different regions of a spacetime, or different spacetimes altogether.

Evaporating Wormholes [PDF]

open access: yes, 2019
There has been a resurgence of interest in wormholes, and continued growth in the study of primordial black holes, opening up new questions about these objects and their possible existence in our universe.

Cylindrical wormholes in DGP gravity [PDF]

open access: yes, 2013
We construct traversable thin-shell wormholes in the Dvali-Gabadadze-Porrati theory with cylindrical symmetry applying the cut and paste procedure to a flat black string solution of the fivedimensional vacuum Einstein field equations.

THE PHYSICS OF TIME TRAVEL: POSSIBILITIES AND PARADOXES

open access: yesWorldwide Journal of Physics, 2022
This study investigates the scientific plausibility, paradoxes, and theoretical implications of time travel using a mixed-methods approach that integrates mathematical modeling, computational simulations, and philosophical interpretation.
