Black hole remnants due to GUP or quantum gravity?
, 2005 Based on the micro-black hole \emph{gedanken} experiment as well as on general considerations of quantum mechanics and gravity the generalized uncertainty principle (GUP) is analyzed by using the running Newton constant.

Black hole Cosmos and the Micro Cosmos
International Journal of Advanced Astronomy, 2013 Point of ‘big bang’ can be considered as the center or characteristic reference point of cosmic expansion in all directions. If so, the existence of ‘preferred direction’ in the universe may not be wrong. Based on the Mach’s principle, it can be suggested that, within the ‘Hubble volume’ overall distribution of ‘Hubble mass’ will explain the observed ...

Viewing the Shadow of the Black Hole at the Galactic Center [PDF]
, 1999 In recent years, the evidence for the existence of an ultra-compact concentration of dark mass associated with the radio source Sgr A* in the Galactic Center has become very strong. However, an unambiguous proof that this object is indeed a black hole is
