Finally a book whose author does not hesitate to tell the truth. The astrophysics, cosmology and more have gone too far in speculation on digital models ignoring all laws and observations. Strictly speaking there is no longer a science because the scenarios are not demonstrated much less reproduced several times. The author has the courage to launch a kick in the anthill and take stock of what we know: statements of the main laws governing astronomy and strongly fight articles announcing unproven discovery. This book was a great help because I must admit after reading some forty in the field of astrophysics, I began to ask myself some serious questions about the veracity of the works. Do not confuse science and philosophy.
