Richard,
Your meditations raise wonderful questions! “But where is this motion going? Does it have a telos?” I love these questions because they are objectively unanswerable, as far as we know, and at the same time they offer a wide open invitation to subjective response. They are examples of the kind of questioning that leads to creative work in both the arts and sciences. Personally, I suspect that many of the great Why’s we bump into have to do with creativity, our own and that of the cosmos itself. Why planets? Why galaxies? Why people? Why backgammon? Because creativity! I think that connects with your idea of eternity too. Creativity is one way we can access that feeling of time standing still that you describe.
Warmly,
Joanna
