The universe is infinite, as evidenced by its inordinate size, its geometric shape that is still unclear, with a rather flat curvature, and its infinite number of bright stars that allow us to observe dazzling night-time darkness. This presentation will introduce various notions, including the observable Universe, the curvature and topology of space-time, and expansion, in oder to deconstruct the above-mentioned paradoxes. Then, if the debate on the infinitude of the Universe is not closed, it will be closed for discussion.
