It is indeed an extraordinary thing! I have just come in from some stargazing under a beautiful clear dark sky. As I was observing NGC 1097 I reflected on your comment that the photons that have traveled 40 million years to enter my eye and become part of my experience would themselves have done the trip in one instant. Quite a koan really.
