Superposition isn’t a physical coexistence of states, it’s a discretized potential, an unmined field of possibilities. These states don’t “exist” as a computable substrate; they are simply the unresolved entropy of the system. Until energy is spent to collapse that entropy into a single outcome, nothing is real, nothing is measurable, nothing is “at once.” They have not yet been mined, meaning they have not yet been measured. Physics has mistaken the mempool for the ledger.
