The Further Future

A good sequel should tell us that there was a lot that we did not know while we were reading the prequel. In Greg Bear's Eon, the Jarts seemed to be conquering aliens, conventional sf villains. We learn about them in Eternity. It is always possible that two groups that are fighting now will be united in the future so what happens if contact with that future is established now?

I enjoy the immediacy of posting about a novel while still reading it. This allows a focusing on details that might otherwise be forgotten but it also means that I might make a provisional comment that has to be revised or amended later - but that is an acceptable risk and a learning process.

The Way, an artificial hypercosmic corridor, endures and extends from our near future to the end of this universe. Some people have traveled the entire length of the corridor right to the far end and one has returned, a very changed man if still a man. He bears a message from the Final Mind: the Way is (somehow) an obstruction to our plans; please destroy it from your end. But how can this be done? Could we send a message to the ancient Egyptians: we don't like your pyramids so, having constructed them, please destroy them?

This is a question, not a rhetorical question. I do not understand the physics of superspace.
