Paradox of the invariance of the speed of light


In this book, I have presented the reasons why the speed of light cannot be invariant in all possible cases in the framework of absolute simultaneity. I have attempted to answer the main criticisms liable to be put forward against my objection about the spaceship and the missile. The book also includes several spacetime diagrams, along with my explanations and comments.  The Appendices include a circular letter to specialists in the field, as well an open letter to Lee Smolin, in which I express the hope that these ideas may open the way to developing a new conception of spacetime.
