Some interesting new research is finding that the brain [actually mind] creates virtual spaces into which it produces geometric forms as a way to process complex thinking. When the process is complete, the spaces are deleted.
The graphic is of particular interest.
R. Buckminster Fuller wrote the 2-volume Synergetics which he subtitled “Explorations in the Geometry of Thinking.” He mapped how the mind and the world were structured with “all-space filling geometry.”
In a sense, the world is structured in cosmic mind. We experience similar in local mind but don’t (thankfully) manifest most of that.
The article mentions higher dimensions which I find a less useful way to frame it. A better understanding is the creation of nested virtual spaces. The world is structured like a Russian doll, layer within layer, with our physical experience being the inner-most doll. Unless we refine our perception, we’ll never see further than the inner surface of the next doll out.
