Imagine the Universe as an ocean of fractal patterns. The same patterns emerge from the behavior of similar systems at different scales and in different dimensions. Neurons express the “branching” fractal shape, just like brains, blood vessels, lungs, trees, rivers, and evolution. Galaxy clusters express the “foam” fractal shape, as do soap bubbles, bread, and volcanic rocks. The shape of each system is an emergent property that arises from the interactions between its components. Neurons branch because they must expand by dividing their extensions. Galaxies foam because of low density bubbles expanding over time. Their 3-dimensional web shapes appear similar, but the 4-dimensional ones are different. Other comparisons between natural systems may be more accurate. By examining physical systems and discovering repeating fractal shapes and patterns, we begin to percieve the true nature of reality.
