The book you hold in your hands is considered a landmark work, both for the general public and for the scientists themselves, one of those books that have left a mark while always remaining relevant.

Its author, Steven Weinberg, perhaps the greatest living physicist, belongs to that old breed of scientists who possess a deep knowledge of their field. A Nobel Prize winner for his work in elementary particle physics, he also has a portfolio of reference books in both particle physics and gravity and cosmology, something no other physicist has achieved in the post-war era.

This book is the first to address the history of the primordial universe, convincing both specialists and laypeople that not only is this considered possible but that it "works" quite satisfactorily. For this reason alone, it should be read by anyone interested in learning what our History is.

“It is exciting to be able to describe the conditions that prevailed in the universe at the end of the first second, or the first minute, or the first year. It is a pleasure for a physicist to be able to examine things numerically, estimating that at a certain time the temperature, density, and chemical composition of the universe had specific values. The truth is that we are not yet quite certain when we talk about these matters, but it is encouraging that we are now able to express opinions about the early universe, albeit with some reservations. This very exciting experience is what I want to convey to the reader,” writes Weinberg himself in the book's preface.

Thus, it is the story of the most significant and exciting phase of the primordial universe. At the same time, it addresses the history of the most important and exciting phase of matter itself, as its components, the elementary particles, have not always taken the form they have today, but have also undergone continuous transformations and mutations.

The theory of the Big Bang and the description of the first three minutes of creation are masterfully unfolded in the pages of this book, forever changing the way we perceive the universe.
