I'm really eager to see a physicist weigh in on this. However, as a simply ordinary person who skipped physics in high school (and calculus) let me say I loved this blog. It made perfect sense to me. I understood the business about the ball moving, and time dilation. Because I am a humanist (actually have a degree in the humanities 😅) I see the effect this information has on our concept of reality.
When people say "God is Dead" what they often mean is the old rules don't apply. Everything we thought was fixed and certain about the universe, is not. As you show in your blog, there are rules, but they are new. And not all of us understand them. Before, we thought we knew why apples fell to the ground and we believed we knew that the earth and the moon were fixed in their orbits and in their relationship to each other. Now we have time dilation...and unanswered questions.
The effect on literature, on our psyches...immeasurable. You write this beautifully. As you can see, your exercise is provocative. Great blog.
