1. Physical Basis- Time emerges from our sensation of light-speed moving space- The space motion producing time is dispersive, radiating outward from an observer- Unlike linear motion which is symmetric, this dispersive motion has no symmetry- Motion only occurs in one direction - from observer towards infinite space2. Relativistic Perspective- Relative motion between observers causes time dilation- At light speed, time appears frozen to each observer- Exceeding light speed doesn't imply backwards time flow- Zero length at light speed means no possibility of faster-than-light motion3. Gravitational Effects- Different gravitational fields have different time flow rates- Time may vary in speed across cosmic locations- However, varying speeds don't enable backwards flow- Time comparisons only meaningful between different locations4. Observer Dependency- Time sequence is relative to observers- Like directions (N/S/E/W), time requires an observer- Without observers, there's no: - Time sequence - Speed comparisons - Possibility of reversal5. Key Conclusions- Time backward flow is physically impossible due to space's dispersive nature- Time travel to the past isn't prevented by time's non-existence- Rather, it's prevented by the fundamental directionality of space-time- Time exists in relation to observers but cannot reverse its flow
