How motion changes time

追加: 2026-05-26

[00:00:00]Time behaves differently depending on motion and position.

[00:00:03]Speed and gravity change how time passes.

[00:00:07]In orbit, clocks tick at a slightly different rate than they do on Earth.

[00:00:12]This isn't abstract physics. Without these adjustments, systems like GPS would accumulate massive errors.

[00:00:20]Time isn't fixed. It depends on where you are.

[00:00:24]The full video connects this to how we understand reality itself.
