Afterglow Of Creation by Marcus Chown

Decoding the message from the beginning of time

A lively, accessible account of how the faint relic radiation from the Big Bang was discovered and studied, explaining the physics and history behind the cosmic microwave background and how its subtle fluctuations reveal the universe’s age, composition and large-scale structure; the narrative weaves together the key experiments and observations, the scientists involved, and the theoretical advances (including inflation and structure formation) that transformed a serendipitous signal into a precision tool for cosmology.
