Timmy pressed his nose to the freezing window. "Is it one of them, Daddy Harry? The things that could talk to the stars?"
The pilot answered: "Ach, no, Timmy—military, it is." And Malibert said:
"They wouldn't put one of those here, Timothy. It's too far north. You wanted a place for a big radio telescope that could search the whole sky, not just the little piece of it you can see from Iceland."
And while they helped slide the stretcher with the broken child into the helicopter, gently, kindly as they could be, Malibert was thinking about those places, Arecibo and Woomara and Socorro and all the others. Every one of them was now dead and certainly broken with a weight of ice and shredded by the mean winds. Crushed, rusted, washed away, all those eyes on space were blinded now; and the thought saddened Harry Malibert, but not for long. More gladdening than anything sad was the fact that, for the first time, Timothy had called him "Daddy."
In one ending to the story, when at last the sun came back it was too late. Iceland had been the last place where human beings survived, and Iceland had finally starved. There was nothing alive anywhere on Earth that spoke, or invented machines, or read books. Fermi's terrible third answer was the right one after all.
But there exists another ending. In this one the sun came back in time. Perhaps it was just barely in time, but the food had not yet run out when daylight brought the first touches of green in some parts of the world, and plants began to grow again from frozen or hoarded seed. In this ending Timothy lived to grow up. When he was old enough, and after Malibert and Elda had got around to marrying, he married one of their daughters. And of their descendants—two generations or a dozen generations later—one was alive on that day when Fermi's paradox became a quaintly amusing old worry, as irrelevant and comical as a fifteenth-century mariner's fear of falling off the edge of the flat Earth. On that day the skies spoke, and those who lived in them came to call.
Perhaps that is the true ending of the story, and in it the human race chose not to squabble and struggle within itself, and so extinguish itself finally into the dark. In this ending human beings survived, and saved all the science and beauty of life, and greeted their star-born visitors with joy…
But that is in fact what did happen!
At least, one would like to think so.
