2) Follow the complexity. Entropy which is no movement in no dimension to more movements in more dimensions.
3) Make the smallest package possible. A circle.( a spacetime quanta)
4) Fill that package with as much energy as possible.
5) Put all those packages together. First, like packing pennies. (2d) Second, like filling a container with balls. (3d)
6) See... the touching points are the only ways that energy can go from one place to another place . Pennies, 2d, has 6 ”kissing numbers”. Balls, 3d, have 12 “kissing numbers.
7) Our universe is filled with these quantas of energy. We cannot notice the majority of them.
