Martín López-Corredoira is a permanent staff astrophysicist at the Instituto de Astrofísica de Canarias (IAC) in Tenerife, Spain. He has authored around a hundred papers (half of them as first author) on galaxies and cosmology in international refereed scientific journals. He is also a philosopher with academic training and has published several papers and a number of books on the philosophy of science and natural philosophy.
The subtitle gives an idea about the contents: it is mainly about the pillars of the standard model of cosmology (expansion, dark matter, dark energy, the CMB, bigbang nucleosynthesis, structure formation) and alternative explanations for various aspects. The book provides not only a good summary of the standard model but also of alternatives to it. It is rare that someone is so well informed both about standard cosmology and alternative theories.
