How can there be greater than maximal structure?
- pizza 5y agoI might have messed up that wording.. basically as I understand it the universe started out pretty much homogeneous and uniform, minor deviations became magnified into seeding the structure that exists today, and basically some mix of inflation + gravitation will create additional structure forever, as measured by a value called the "shape potential" C = l_rms/l_mhl of a spatial configuration of particles [0]. l_rms is the root-mean-square length of the system and l_mhl is the mean-harmonic-length. He makes this argument that there are many potential geometric configurations that the universe could have started out as but he believes it started from the one that has the maximum shape potential, iirc.
