Adopting the Uncertainty Principle for the Entropy Estimation of Black Holes, de Sitter Space and Rindler Space
Tetsuya Hara, Keita Sakai, Daigo Kajiura
By a simple physical consideration and uncertain principle, we derive that temperature is proportional to the surface gravity and entropy is proportional to the surface area of the…

On the Entropy Increase in the Black Hole Formation
Tetsuya Hara, Keita Sakai, Daigo Kajiura
The entropy increases enormously when a star collapses into a black hole. This entropy increase is interpreted as the decrease of the temperature due to the increase of the volume.…
