I've never looked at the printed version, so I'm sure the "Voices from the Universe" sections don't seem as redundant as much as recaps that read as if I wasn't paying attention to what I just read (heard). Facts are spewed willy-nilly, and it can be a bit overwhelming listening to (or reading) the lists that go on and on—dates, names, figures—they get a little boring. A few random facts stood out to me, and I hope to retain enough before I listen again.
It's not a terrible book, but it's a little condescending in its presentation. The "questions" that are answered are pretty elementary, and a few are downright dumb. It also gets a little frustrating when Oliver Wieman (the person reading the book) is mispronouncing so much. Still, it's good for a sweeping background on some of the history of our understanding of the universe.
