One of the foremost French astrophysicists, Jean Audouze, and biologist Marie-Christine Maurel, get together to discuss a topic still intriguing humanity: birth of our universe and of life.
First was the universe. Its birth occurred about 13.7 billion years ago. From elementary particles to galaxies clusters, their interactions are governed by four essential interactions: gravity, electromagnetism and two nuclear forces. Since then, several generations of stars (and their clusters, named galaxies) took shape during the first billion years. Most of the chemical elements, including those that created Earth and life, emerged among stars, especially the biggest ones.
Water on Earth had an essential role. Two eras marked the evolution and the development of life: the first one, with the lack of oxygen on Earth; the second one, when it appeared, about 2 billion years ago.
The authors recount the evolution of life until the appearance of Homo Sapiens, the transformation of ecosystems – and fears induced by global warming and the exhaustion of biologic diversity.
