Is this a good time to say that I’ve changed the title ?
I’m going to call it Empty Space, which comes from the much-quoted
“No point is more central than this, that empty space is not empty. It is the seat of the most violent physics.” –John Wheeler.
but also refers to the emptiness of the culture in which the characters live & the value-shaped gap in the lives of most of them.
Empty Space was the working title for Light. It will probably be the overall 3-volume title too.
