Did our Universe have a beginning? Is it finite or infinite? Why does nearly 95% of our Universe seem to escape us? What is the destiny of our Universe? So many questions for which we currently have no answers or only a few fragments. According to the current model, the Big Bang would have given birth to a few atoms. Then, it is the stars, essential atom factories, which would manufacture the elements that make up everything we know. And, it is when they die that they seed the Universe, with all the elements that they have created during their life.
