Query: Physics lessons hidden in epic fiction

This book had some great information about stellar physics and then proceeded to a tour of some truely giant machines of war. The humans are primitives getting to view some of the battle fields of the photino vs. xeelee war. The view is fantastic. Galactic scale machines using, and being undone by, quantum effects.Add in the usual Baxterisms of human societies evolving over millenia. In Ring, however, I think the character development is a bit better than in some of the other books.
