>[!warning] >This content has not been peer reviewed. The independent, physical active substrate of reality. It exists regardless of observation. [[Information]] is the tool used to navigate it. The [[Format]] is not uniform. The local [[Proper Time|refresh interval]] ($\tau$) and temperature ($T$) vary by [[Location]]. Gravity is a property of the [[Format]]: it curves the substrate so that $\tau$ differs across positions. The [[Format]] determines the cost of [[Translation]]. The constants $k_B$ and $T$ in the [[Energy Floor|Landauer equation]] are properties of the substrate, not choices of the observer. The [[Format]] is not directly observed; it is inferred from the resistance it provides. [[You]] choose what to maintain ($\sigma$); the [[Format]] determines the price ($k_B T \ln 2$). This observer-independence is the evidence of something beyond [[Information]]. **Overview of concrete properties:** For a single list of all the concrete properties of the substrate we know (cost, capacity, resolution, geometry, saturation, dynamics, protection) — with values, bounds, and links to the knowledge notes that establish them — see **[[expanded theory/Concrete properties of the substrate]]**. Temperature ($T$) is the [[Format]]'s local noise level at a given [[Location]]. It sets the price per bit of [[Translation]]: higher $T$ means more error correction, raising the [[Energy Floor]]. The format has a finite capacity — a **saturation limit** beyond which relational friction exhausts the budget; see **[[expanded theory applied/further applications/E8 Compatibility/Saturation limit of the format]]**. --- ## RRT Formalization **Ref:** [[Relational Resolution Theory (RRT)]], Section I.1. **Logic:** The Format ($f$) is the independent, dynamic substrate. It determines the physical constants ($k_B$, $T$) that set the cost of [[Translation]]. ___ ## In the Equation **"The Noise"** ($T$) $T$ is the temperature of the substrate at a given [[Location]]. Combined with $k_B \ln 2$, it sets the energy price per bit: $k_B T \ln 2$. Higher $T$ means more error correction, higher cost.
