Originally written in 1986 and substantially updated in 1998, Gribben's telling of the tale is once again an excellent read. Trained as a physicist, he became a full-time science writer within a few years of receiving his PhD. Good for us he did. He takes difficult material and makes it understandable without condescension. There have been advances in astrophysics and cosmology since 1998, but this book can give you the background you need to understand the latest developments. If you love science, give Gribben a shot - he's very good at what he does.
