Underpinning the universe: its scales, holography and fractality

Abstract

We expand on the general concept of a universe. We identify physics as a unit applied to a universe. Then we generalize the concept of a quantum black hole, and apply it to the unit of a universe. We find that only one parameter, the Pin, is needed to define all its physical properties. Here we present three significant quantum black holes, three scales: Planck's, sub- Planck and our own universe as a whole. Then we revise the holographic and fractal properties, and propose a sequential growing process to explain the evolution and the basic structure of our universe.
