On a regular modified Schwarzschild spacetime
Hristu Culetu
A modified version of the Schwarzschild geometry is proposed. The source of curvature comes from an anisotropic fluid with and fluctuating tangential pressures. The ev…
Comment on "The entropy of a hole in spacetime"
Hristu Culetu
Balasubramanian, Czech, Chowdhury and de Boer \cite{BCCdB} studied a "spherical Rindler space" and found that accelerating observers are causally disconnected from a spherical regi…
On a de Sitter-like spacetime with cylindrical symmetry
Hristu Culetu
A curved static de Sitter-like metric is analyzed. The source of curvature is rooted from a constant stress tensor with positive energy density and negative pressures. All the curv…
Anisotropic fluid in a time dependent conformally flat spacetime
Hristu Culetu
The special conformal transformation (composed by inversion - translation - inversion) is used to generate a time dependent conformally flat spacetime. In order to be an exact solu…
On a free of centrifugal acceleration spacetime
Hristu Culetu
A static spacetime with no centrifugal repulsion, previously studied by Dadhich, is investigate in this paper. The source of curvature is considered to be an anisotropic fluid with…
