Through endless skies

My son Dom and I have a habit of sending each other interesting songs that we come across, and he recently sent me this one, ‘Planet Caravan‘ by Black Sabbath, about the singer wandering through the universe with his lover.

Listening to it reminded me of one very simple reason why I write science fiction rather than realist fiction.  If you are going to make stuff up, why confine yourself to the narrow and parochial limits of our little patch of space and time?
