The last paralus was passing into the outskirts of its own solar system, having traveled a light year through a maze of planets, satellites and meteors. Beyond its prow glimmered the cloud of ices, volatiles, and planetesimals, possibly the very origin of wandering comets and the limits of their known worlds. Deterioration had set into the ship and into the bodies of the paraloi. It would be a matter of hours or days until complete disintegration, and it was more than likely that they would not breach and pass beyond the cloud of planetesimals. They listened to their mournful music and drank. At last, the captain of the paraloi gave a speech in the form of a parable. It is the last hour, he said, and we have come to the very limits of what we can know. Our crew of brave paraloi consists of the only survivors of life in our solar system. The cost of our efforts has been great. Five planets have been ruined, four destroyed, and others damaged so that we might arrive at this moment. There is no life ahead and none behind. What we may know, what is truly real, is this moment. Once upon a time, there was a fiery visionary, a heretic, who said that there were other suns with other exoplanets circling around them, and that our first world was not the limit of what we could navigate. And he said that the universe is infinite. The philosophers said he was wrong because his views did not agree with what they taught. The scientists discovered that there were indeed other suns with other exoplanets, but they said he was wrong because he only guessed without any evidence. One of his closest enemies discovered the rivers of the outer planets by looking through a telescope. For years, successive generations of better telescopes and mathematics confirmed the existence of these rivers. It was not until the first paralus to pass by the planets of rivers that we learned differently–the rivers were an optical illusion. There were no rivers. I cannot help but feel that the universe has an end somewhere, that it is finite and bounded. I do not know what the universe or matter is. Our voyage, however, seems increasingly infinite.
