The two beings linked themselves together in some fashion unknowable to man and shot away through the airless, heatless void. Heatless, but by no means devoid of energy; the travelers could draw sustenance enough for their ordinary needs from the cosmic radiation pervading all space. Across Rift Two Hundred Forty they flew and on through interstellar space. They reached our solar system. On the third planet, our Earth, they found several atomic power plants. There were no loose atomic vortices—then. “Hold on! Wait!” Litosa exclaimed, and the strangely-linked pair stopped just short of the glowing bit of warmth—the ragingly incandescent, furiously radiating reactor in the heart of one of Earth’s largest generating stations—which was its goal. “There’s something funny about this. How could there possibly be even one little spark like this, to say nothing of so many, on such an utterly frigid planet, unless some intelligent being started it and is maintaining it for some purpose? There MUST be intelligence on this planet and we must be intruding shamefully. Have you scanned? Scanned. CAREFULLY?” “I have scanned. Carefully, completely. Not only on this planet’s surface, but throughout its depths. I have scanned, area by area and volume by volume, this sun and its every planet, satellite, and asteroid. There is no intelligence here. More, there is no sign whatever of any kind of life, however rudimentary, latent, or nascent. I have been able to find nothing whatever to modify our conclusion of long and long ago that we are the only life, intelligent or otherwise, in existence. Scan for yourself.” Litosa scanned. She scanned the sun, the planets, the moons and moonlets, the asteroids down to grains of sand and particles of dust. Still unsatisfied, she scanned all neighboring solar systems, from Centralia to Salvador. Then, and only then, did she accept Medury’s almost unacceptable conclusion that these providential sparks were in fact accidental and were in fact, by some process as yet unknown to Cahuitan science, self-balancing and self-sustaining. Medury and Litosa, woven into a fantastically intricate and complex sphere of ultra-microscopic filaments, flashed into the heart of the reactor, which thereupon went instantaneously and enthusiastically out of control. And from the pleasant warmth of the incubator-womb—to us of Earth the ravening fury of the first loose atomic vortex—there emerged the fulfillment Medosalitury. This entity, grave and complete and serene as an adult Cahuitan should be, wafted itself (there is no question as to which pronoun is to be used here) sedately back to its home planet. And in the pleasant warmth of that same incubator-womb the two products, Midora and Letusy, began very slowly to gestate. * * * * *
