Hypothesis of Conserved FTL

A theoretical hypothesis proposing that faster‑than‑light (FTL) information transfer does not automatically result in time travel or causality violations, because causality is conserved across all observers through unknown mechanisms. Unlike classical interpretations where FTL implies backward time travel (the tachyonic antitelephone), this hypothesis suggests that any FTL communication would be accompanied by compensatory effects that preserve causal order—perhaps through higher‑dimensional constraints, observer‑dependent timelines, or hidden variables that align events consistently. In other words, FTL and causality are not mutually exclusive; they can coexist if the universe has built‑in “conservation laws” for causal structure. The hypothesis opens the door to speculative technologies (warp drives, instantaneous communication) without paradoxes, by positing that nature has its own way of keeping the timeline intact—mechanisms we don’t yet understand but could theoretically exploit.

Hypothesis of Conserved FTL Example: “The paradox of sending a message to your own past disappears under the hypothesis of conserved FTL: causality is preserved because any FTL signal would be ‘compensated’ by the universe—it would arrive in such a way that no paradox could form, perhaps by always appearing to travel at light speed in any causal frame.”
