The First Law of Information: "Information Cannot Originate from No Information"

We propose and formalize the **First Law of Information**: “Information cannot originate from no information.” This law imposes a foundational constraint on physical explanation, asserting that informational structure cannot arise from a state lacking antecedent informational content. We present three independent proofs: the logical-impossibility proof; the principle of sufficient reason proof; and an algorithmic information proof. We also situate the law within contemporary physical theory and the philosophy of science. In light of recent experimental and theoretical developments establishing information as a physical quantity (Landauer, 1961; Bennett, 2003), we argue that this law is consistent with, and complementary to, current physics. The First Law of Information constrains explanatory mechanisms in physics, cosmology, and computation; demanding that any physical account of informational origination presuppose some informational structure.
