I am reading Silentium, which I am loving, but notice the distances that Forerunners travel within the Milky Way cannot be true. Maybe you have already addressed this in corrections, but the Galaxy is only about 48 thousand light years in diameter. The ships in this book repeatedly go much longer distances and stay in or near the galaxy. The large magellenic cloud (Path Kethona) is about 160K light years. You have some ships going dozens of millions of light years to get there. The Andromeda Galaxy is within 3 million light years. The entire supercluster of galaxies is only 110 million light years wide, so the distances in these books is clearly inconsistent with facts. Correct me if I'm wrong, but the book is almost entire intra-galactic, with the exception of the Flood. Thanks and I hope there are more books on the way!

Actually, the galaxy is about a hundred million light years in diameter, perhaps as much as 120 million--the figure I was working with. The distance to Path Kethona, or the greater Magellanic cloud, a satellite galaxy, is about 160 million light years--from Earth. Big enough to boggle my mind, Scott! Glad you're enjoying the books.
