Book Review: Billions & Billions: Thoughts on Life and Death at the Brink of the Millennium: Carl Sagan

Billions & Billions: Thoughts on Life and Death at the Brink of the Millennium: Carl Sagan: 9780345379184: Amazon.com: Books. This is probably the worst thing that Sagan has been involved in. Avoid. Things are factually wrong, inconsistent and he really needed someone to say “No” to this book.
