I went to the librarian and asked for a book about stars…and the answer was stunning. It was that the sun was a star but really close. The stars were suns, but so far away they were just little points of light…the scale of the universe suddenly opened up to me. It was a kind of religious experience. There was a magnificence to it, a grandeur, a scale which has never left me. Never ever left me.
