A principle proposing that causality is subject to a conservation law—that the total amount of causal structure in the universe remains constant. Conservation of Causality suggests that you can't create new causes or destroy old effects; you can only rearrange causal relationships. This has implications for time travel (you can't create paradoxes because causality is conserved), for quantum mechanics (entanglement redistributes causality), and for free will (our choices are causal transactions, not violations). It's causality as a budget: you can spend it, but you can't print it.
Conservation of Causality Theory "Time travel stories always have paradoxes—kill your grandfather, you're never born. Conservation of Causality says: can't happen. Causality is conserved; you can't create a loop that breaks the budget. Time travel might be possible, but paradoxes aren't—causality won't allow it."

A fundamental principle proposing that causality is conserved—like energy, momentum, or charge—across all physical interactions. Theory of Conservation of Causality suggests that cause-effect relationships cannot be created or destroyed, only transformed or redistributed. In this framework, apparent causality violations (quantum indeterminacy, time travel paradoxes) are actually transformations: causality moves elsewhere, changes form, but the total causal structure remains constant. The theory provides a budget for reality: you can spend causal influence, but you can't print it. Every effect must be paid for by a cause somewhere, sometime.
Theory of Conservation of Causality "Time travel stories always have paradoxes—kill your grandfather, you're never born. Conservation of Causality says: can't happen. Causality is conserved like energy. You can rearrange it, but you can't destroy it. The paradox is impossible because causality has a budget, and you can't overspend."

A framework proposing that even in faster-than-light travel, causality is conserved—not violated, just transformed. The Theory of Conservation of Causality in FTL Scenarios suggests that FTL doesn't create paradoxes because causality, like energy, has a budget. You can spend it, move it around, but you can't destroy it. In FTL travel, causal influence might be redistributed across spacetime in ways we don't yet understand—but the total causal structure remains constant. The theory resolves the classic "FTL equals time travel" paradox by positing that causality is conserved: any apparent backward causation is balanced by forward causation elsewhere. You can't kill your grandfather because causality has a budget, and that transaction would overdraw the account.
Theory of Conservation of Causality in FTL Scenarios "They said FTL means time travel—therefore impossible. Conservation of Causality says: maybe causality is conserved, like energy. The ship goes FTL, but somewhere, somehow, causality balances the books. No paradox, just physics we don't yet understand. You can't kill your grandfather because causality won't approve the transaction."
