Comment on "Empty Black Holes, Firewalls, and the Origin of Bekenstein-Hawking Entropy"
Hristu Culetu
Saravani, Afshordi and Mann \cite{SAM} considered a surface fluid with vanishing energy density on the stretched horizon of a black hole, taken as the new boundary of spacetime. We…
Comments on "On the Origin of Gravity and the Laws of Newton", by Erik Verlinde
Hristu Culetu
We argue that the relativistic Unruh temperature cannot be associated with the bits on the screen, in the form considered by Verlinde. The acceleration is a scalar quantity (th…
Boundary stress tensors for spherically symmetric conformal Rindler observers
Hristu Culetu
The boundary energy - momentum tensors for a static observer in the conformally flat Rindler geometry are considered. We found the surface energy is positive far form the Planck wo…
Light Dragging Phenomenon and Expanding Wormholes
Hristu Culetu
The null geodesic congruence for the Lorentzian version of Hawking's wormhole is studied, in spherical Rindler coordinates. One finds that the wormhole throat expands exponentially…
On the near horizon approximation for the Schwarzschild black hole
Hristu Culetu
An anisotropic fluid with a negative radial pressure is supposed to exist near the horizon of a Schwarzschild black hole. The constant energy density depends only on…
Bjorken expansion in the isotropic Kasner spacetime
Hristu Culetu
An isotropic expansion for the QGP is proposed in curved Kasner spacetime for an experimental configuration with three dimensional set of beams. The fluid of relativistic particles…
