When we look at space, we naturally imagine straight lines. If light travels from Earth to the Moon, we imagine a smooth path between two points. If we draw a square, the shortest route from one corner to the opposite corner is the diagonal. If we draw a cube, the shortest route from one corner to the opposite corner is the body diagonal. That is how geometry teaches us to think. But information theory starts from a different question. It does not ask: What is the shortest geometric path? It asks: What channels are available for information to travel through? This difference is very important. In information theory, information does not automatically travel through a diagonal just because the diagonal is shorter. Information travels only through defined channels. If there is no channel, there is no direct transmission. This gives a simple way to understand the Ghidan Planck-cube model. The model does not need to contradict information theory. In fact, it can be understood as a natural extension of information theory into a possible physical substrate. The key idea is this: Information travels through channels first. Geometry appears later.
