I see a frightening-amusing feature in this edifice, whose total knowableness without reservation Einstein so confidently professed—he, the creator of a theory that contradicted his confidence, because it led to a place where it itself broke down, and where every theory must break down: in the world torn asunder. For it foretells sunderings and exits which it cannot itself penetrate; yet one can exit from the world anywhere, provided one strikes a blow at it, of the force of a star in collapse. Is it physics alone which appears incomplete under such constraints? Are we not reminded here of mathematics, whose every system is incomplete as long as one remains inside it, and which can be grasped only by going outside it, into richer domains? Where is one to look for them, if one stands in the real world? Why does the table made of stars always wobble on some singularity? Can it be that a growing Intelligence encountered the frontiers of the world, before it encountered its own? And what if not every exit from the Universe is equal to annihilation? But what does it mean, that one who leaves cannot return, even if surviving the transition, and that the proof of this impossibility of return is accessible here? Can it be that the Universe was designed as a bridge, designed to collapse under whoever tries to follow the Builder, so they cannot get back if they find him? And if he does not exist, could one become him?
