Just noticed something in The Long Cosmos' blurb, at the end of the last sentence -
"It's impact will be felt by and resonate with all - mankind and other species, young and old, communities and individuals - who inhabit the Long Earths..."
It says "the Long Earths", rather than "the Long Earth"!
You know in The Long Mars, when Frank, Sally and Willis are on Gap Mars East 1 and they look up at the earth in that universe, and it's not Gap East 1? Wouldn't that earth that they see be in a different chain of Earths to our Long Earth? Meaning that it would be in a seperate Long Earth, and that there are multiple!
Is that what the blurb is talking about? What do you guys think? Had you noticed this already?
