It follows from what has been said, that closed spaces without limits are conceivable. From amongst these, the spherical space (and the elliptical) excels in its simplicity, since all points on it are equivalent. As a result of this discussion, a most interesting question arises for astronomers and physicists, and that is whether the universe in which we live is infinite, or whether it is finite in the manner of the spherical universe. Our experience is far from being sufficient to enable us to answer this question. But the general theory of relativity permits of our answering it with a moderate degree of certainty, and in this connection the difficulty mentioned in Section XXX finds its solution.

Il résulte de ce qui précède que des espaces fermés sans limites sont concevables. Parmi eux, l’espace sphérique (et l’espace elliptique) se distingue par sa simplicité, puisque tous ses points sont équivalents. Cette discussion fait surgir une question des plus intéressantes pour les astronomes et les physiciens : l’univers dans lequel nous vivons est-il infini, ou est-il fini à la manière de l’univers sphérique ? Notre expérience est loin de suffire pour nous permettre de répondre à cette question. Mais la théorie générale de la relativité nous permet d’y répondre avec un degré modéré de certitude, et la difficulté mentionnée à la section XXX trouve dans ce contexte sa solution.
