Theory of Conservation of Causality in FTL Scenarios

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."
