Time, Space and the Core Secrets of the Universe-Zhang Xiang Qian

5-6 Why Time Cannot Flow Backwards (16)

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 space

2. 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 motion

3. 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 locations

4. 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 reversal

5. 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
