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