But to keep such structures stable, you’d need exotic matter with negative energy density, something not yet known to exist in usable quantities. Quantum mechanics complicates it even further — paradoxes like the “grandfather paradox” emerge, though theories like the Novikov self-consistency principle and many-worlds interpretation might resolve them by allowing consistent or branching timelines. | But to keep such structures stable, you’d need exotic matter with negative energy density, something not yet known to exist in usable quantities.

Some quantum gravity models suggest that “past” and “future” are just relationships between events, not fixed directions — meaning time travel might be reinterpreted as navigating a higher-dimensional structure of reality. | Some quantum gravity models suggest that “past” and “future” are just relationships between events, not fixed directions — meaning time travel might be reinterpreted as navigating a higher-dimensional structure of reality. | ||
