Conversation sur… les multivers: Mondes possibles de l'astrophysique, de la philosophie et de l'imaginaire

by Aurélien Barrau, Jean-Philippe Uzan, Patrick Gyger

Et si notre Univers n’était qu’un parmi d’autres ? Cette idée d’univers multiples, envisagée pourtant depuis l’Antiquité, n’est entrée que récemment – et avec fracas – dans le champ de la science. L’hypothèse fascine, mais elle n’en est pas moins dérangeante : comment se formeraient ces mondes invisibles ? Peut-on tester et réfuter leur existence ? Une telle hypothèse est-elle vraiment scientifique ? Ouvrir la porte aux mondes possibles de l’astrophysique, de la philosophie et de l’imaginaire, c’est montrer qu’il y a une multiplicité de « manières de faire des mondes»…

This is a very interesting book on the scientific and philosophical aspects of multiverses. I was able to learn a lot about the different concepts of the multiverse, there were actually more types of multiverses than I would have expected. The participants were all very knowledgeable and also able to convey their ideas in a way accessible to the general public, although quite a lot of references to major philosophers were left relatively unexplained compared to the scientific concepts that were usually more gently introduced. Still the main philosophical ideas around multiverses are well-presented.

One issue I had with this book is that I wish the moderator would assign speaking times between participants more evenly since some had much more space to speak than others. This problem affects the ‘philosophy section’ of the book the most. Although some important philosophical concepts about the multiverse are discussed, an unnecessarily large section is spent discussing positions around how to do/consider science and relativism, which constitute an interesting debate on their own but in my opinion took away too much screentime from the multiverse discussion.

Me parece interesante la estructura y el tema del libro. Lástima que uno de los científicos acapara la conversación y es insoportable. Interesantes los comentarios sobre Borges. Es el primer libro que lei sobre el tema, pero estoy segura de que tienen que existir libros mejores que este. Igual le pongo 3 estrellas, porque algo aprendí y pude rescatar suficiente.
