I realized yesterday: I have come full circle with my questions about missing people. I followed clues to the end of the earth and walked straight into myself. And the questions begin anew, with different stakes. And new questions are born.
Several years ago, I kept thinking about redshift and blueshift, convinced they held the key.
This past winter, I was thinking again about optics and light. The material became part of another essay about the missing.
Now, I find myself wondering again about distance and movement and light, returning to some ancient ideas and wishing they were true. Or sometimes true.
The cycle holds true for other questions. I no longer believe any one line of inquiry holds the key, but all lead to interesting places.
