The book studies the cosmogonies of ancient civilizations and the emergence of rational thought in Classical Greece with philosophers such as Thales, Anaximander and Heraclitus. It then analyzes the cosmological theories of Aristotle, Claudius Ptolemy and Nicolaus Copernicus.

Subsequently, the origin of modern cosmology is examined with the Big Bang theory, explaining concepts such as the cosmic microwave background radiation, Hubble's Law and the notion of "singularity" at the time of the origin of the universe.

The author argues that the Big Bang theory has serious problems, from mathematical paradoxes to faulty analogies between natural and unnatural phenomena. He concludes that this theory gives exotic properties to matter, reflecting more the minds of its creators than the actual workings of the universe.

In short, a rigorous journey that invites us to critically rethink the foundations of modern cosmology in order to give way to explanations more consistent with the fundamental laws of nature regarding the origins of the cosmos.
