Física existencial

Physicists are excellent at solving questions, but very bad at explaining why we should care about them. Sabine Hossenfelder believes that this attitude of "knowledge concealment" is what gives strength to pseudosciences, and she sets out to remedy it in the pages of this book. According to the author, it is no coincidence that quantum entanglement and vacuum energy have become the go-to explanations for alternative healers, or that people believe that their deceased grandmother is still alive thanks to quantum mechanics when told by a shaman. Science and religion have the same roots and face the same questions: Where do we come from? Where are we going? How much can we know? The area of science that comes closest to answering these questions is physics. In the last century, physicists have learned a great deal about which spiritual ideas remain compatible with the laws of nature. However, they have not always remained on the scientific side of the debate. Has physics ruled out free will? Does the past still exist? Has the universe been created for us? This reading does not give us the definitive answers, but it does explain how far current scientific knowledge goes in an entertaining way, bluntly addressing life's most important questions and asking what physics really has to say about the human condition.
