Gravity quanta, entropy, and black holes

We propose the use of a gravitational uncertainty principle for gravitation. We define The corresponding gravitational Planck's constant and the gravitational quantum of mass. We define entropy in terms of the quantum of gravity with the properly of an extensive quality. The equivalent second law of thermodynamics is derived, the entropy increasing linearly with cosmological time. These concepts are applied to the care of black holes, finding their entropy, and discussing their radiation.
