(10) Why We Say Motion States Are Our DescriptionsThis section explores the relationship between observers and motion description in relativity theory. Key points: Motion description requires observers, and physical concepts (like time, displacement, force) are all relative and meaningless without observers. Without humans, the universe would be like a frozen camera frame, not nonexistent. From a geometric perspective, physical motion states are perpendicular states - these two phenomena are actually one phenomenon viewed differently by observers.
(11) Why Emphasize Your Time/My Time? Your Space/My Space?Unified field theory considers time as our sensation of surrounding space dispersing at light speed. When observers move relatively:
- Time measurement relates to observers and their motion
- Different observers may measure different times for the same event
- Spatial displacement measurements also relate to observers
- These differences are tiny at low speeds but still existAdditionally, for any object in the universe, surrounding space always disperses outward from the object's center, causing all moving observers to have surrounding space different from others.
(12) What Does Relativity Mean by Light-Speed Motion Freezing Time?Using the alien spacecraft example:
- Earth observers think a 50 light-year journey takes 50 years
- Spacecraft observers think the journey takes no time, arriving instantlyUnified field theory explains this as: light-speed motion catches up with time, causing time to freeze and stop.
(14) What Does Relativity Mean by Light-Speed Objects Having Zero Length in Motion Direction?Unified field theory explains:
- Static space doesn't exist; space constantly moves from objects at light speed
- When objects reach light speed, catching up with space's motion speed, space ceases to exist
- According to the Perpendicular Principle: motion states and perpendicular states are equivalent. Light-speed can rotate the original 90-degree perpendicular state by 90 degrees, making one-dimensional space in the forward direction become zero through rotation.
