A Short Essay on Quantum Black Holes and Underlying Noncommutative Quantized Space-Time
Abstract
We emphasized the importance of underlying noncommutative geometry or Lorenz-covariant quantized space-time towards ultimate theory of quantum gravity and Planck scale physics. We focused there our attention on the statistical and substantial understanding of Bekenstein-Hawking's Area-Entropy Law of black holes in terms of Kinematical Holographic Relation (KHR). KHR manifestly holds in Yang's quantized space-time as the result of kinematical reduction of spatial degrees of freedom caused by its own nature of noncommutative geometry and plays an important role in our approach without any recourse to the familiar hypothesis, so-called Holographic Principle. In the present paper, we find out a unified form of KHR applicable to the whole region ranging from macroscopic to microscopic scales in spatial dimension d=3. We notice a possibility of nontrivial modification of Area-Entropy Law of Black Holes which becomes most remarkable in the extremely microscopic system close to Planck scale. We finally refer to the historical background of noncommutative geometry or quantized space-time.
