- Worse, a billion year orbit would circle the galaxy a few times. You would
- have to predict where our sun would be and I think stellar motions in the
- galaxy are too chaotic.

- Imagine Europeans from the year 1493 trying to send a message to us by
- 'carving' it in the earth of the new world. In a billion years the moon
