Membrane of Life
Perhaps a long time ago everything that exists in the universe was united together. At least that's what the big bang theory suggests. At the same time, our universe is characterized by a dichotomy. I think this dualism [1] creates opposites like left/right, this side/next side, light/dark etc. through an apparent separation. If one dispenses with one of the dimensions of the room, one gets a surface with a front and a back like a sheet of paper, which forms a torus ring on the left and right as well as on top and bottom. Its surface is finite but unlimited and curved (almost how the universe presents itself to us) [2, 3]. The front and back of the original surface now form the inside and outer surface of the ring. In principle, this also means that the entire three-dimensional space resp. splitting our four-dimensional space-time, and therefore everything that exists within it, in half (hence duality). But let's stay with the areas. If one postulates that one of the two sides
