چکیده
In this paper, we investigate the light trajectories and shadow properties in rotating version of null naked singularity (NNS) spacetime which is derived using Newman- Janis algorithm without complexification method. We discuss some geometrical causal structure Rotating Naked Singularity (RNS) spacetime. The gravitational lensing a analyzed, results are compared to those Kerr black hole. case hole, photon sphere exists for both prograde retrograde orbits, whereas RNS, only orbits. As result, projects an arc-shaped that differs from contour-shaped cast by

Naked Singularity and Thunderbolt
We consider quantum theoretical effects of the sudden change of the boundary conditions which mimics the occurrence of naked singularities. For a simple demonstration, we study a massless scalar field in (1 + 1)-dimensional Minkowski spacetime with finite spatial interval. We calculate the vacuum expectation value of the energy-momentum tensor and explicitly show that singular wave or thunderbo...
متن کاملHow Does Naked Singularity Look ?
There are non-radial null geodesics emanating from the shell focusing singularity formed at the symmetric center in a spherically symmetric dust collapse. In this article, assuming the self-similarity in the region filled with the dust fluid, we study these singular null geodesics in detail. We see the time evolution of the angular diameter of the central naked singularity and show that it migh...
متن کاملSingularity-robust Trajectory Generation Singularity-robust Trajectory Generation
A singularity-robust trajectory generator is presented that, given a prescribed manipulator path and corresponding kinematic solution, computes a feasible trajectory in the presence of kinematic singularities. The resulting trajectory is close to minimum time, subject to individual bounds on joint velocities and accelerations, and follows the path with precision. The algorithm has complexity O(...
متن کاملPhysical Processes in Naked Singularity Formation
Gravitational collapse is one of the most fruitful subjects in gravitational physics. It is well known that singularity formation is inevitable in complete gravitational collapse. It was conjectured that such a singularity should be hidden by horizons if it is formed from generic initial data with physically reasonable matter fields. Many possible counterexamples to this conjecture have been pr...
متن کاملChronology Protection and Non-Naked Singularity
We test the chronology protection conjecture in classical general relativity by investigating finitely vicious space-times. First we present singularity theorems in finitely vicious space-times by imposing some restrictions on the chronology violating sets. In the theorems we can refer to the location of an occurring singularity and do not assume any asymptotic conditions such as the existence ...
