Billy Carson breaks down the fractal nature of the Universe in this interesting lecture. Carson has a book out called “Compendium of the Emerald Tablets” at the moment which breaks down the Ancient Egyptian tablets of Thoth.
That the Universe is fractal means that each part of it contains a representation of the whole thing, so in every cell of your body there is a whole universe! Many repeating patterns can be found on the micro and macro-cosmic level such as your brains neural patterns being reflected in the structure of the Galactic Super-clusters.
