" There’s a planet called Echo. It doesn’t exist. It’s like those ghost-ships at sea, the sails worn through and the deck empty. It comes on the radar, you fly towards it, there’s nothing there. Our crew were outside, repairing the craft, and we saw it moving at speed right at us. It passed straight through the ship and through our bodies, and the strange thing that happened was the bleach. It bleached our clothes and hair, and men that had black beards had white. Then it was gone, echoing in another part of the starry sky, always, ‘here’ and ‘here’ and ‘here’, but nowhere. Some call it Hope. "

― Jeanette Winterson , The Stone Gods
