Is there Lower Limit to Velocity or Velocity Change?
B. N. Sreenath, Kenath Arun, C. Sivaram
Here we explore the possibility of a lower limit to velocity or velocity change which is 20 orders of magnitude smaller than the speed of light and explore the various observable s…
Extended Equivalence Principle: Implications for Gravity, Geometry and Thermodynamics
C. Sivaram, Kenath Arun
The equivalence principle was formulated by Einstein in an attempt to extend the concept of inertial frames to accelerated frames, thereby bringing in gravity. In recent decades, i…
On a minimum Column Density for Massive Star Formation
C. Sivaram, Kenath Arun
A fundamental physical basis is provided for the recently obtained minimum column density (1gcm-2) for massive star formation.
Some Unique Constants Associated with Extremal Black Holes
C. Sivaram, Kenath Arun
In recent papers we had developed a unified picture of black hole entropy and curvature which was shown to lead to Hawking radiation. It was shown that for any black hole mass, hol…
Hydrodynamics, Vortices and Angular Momenta of Celestial Objects
C Sivaram, Kenath Arun
The current observational evidences suggest there are about hundred billion galaxies in the observable universe and within each, on an average, about hundred billion stars. But no…
