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…
