It's simple to understand, the holographic universe is the particles which are called photonic energy and atomic particles which make up all of the mass and energy in the multiverses. You will find that this energy makes up the galaxies, stars, planets, moons, comets, and asteroids. Even space is not empty.
All living things are also included in this undeniable nature of the grids and all are aligned in a series of quantum grid work where said energy and mass are conducted across the spectrum of light. This spectrum, which is broken into various different shades of primary colors, is projected within the holographic Universe.
