The Alien Years by Robert Silverberg

invaded. This may simply be a friendly visit. It may be a bunch of harmless tourists making a summer cruise of the galaxy. On the other hand, if it is an invasion, it’s being undertaken by a vastly superior civilization and there’s every chance that we are just as helpless before it as Dr. Carlyle-Macavoy says we are.”
    Defense, Navy, Army, and three or four others were standing by that time, waving their arms for attention. The Colonel wasn’t through speaking, though.
    “We know nothing about these beings,” he said, with great firmness. “ Nothing. We don’t even know how to go about learning anything about them. Do they understand any of our languages? Who knows? We sure don’t understand any of theirs. Among the many things we don’t know about this collection of Entities,” he went on, “is, for example, which of them is the dominant species. We suspect that the big squid-like ones are, but how can we be sure? For all we know, the various kinds we’ve seen up till now are just drones, and the real masters are still up in space aboard a mother ship that they’ve made invisible and indetectable to us, waiting for the lesser breeds to get done with the initial phases of the conquest.”
    That was quite a wild idea to have come from the lips of an elderly, retired, walnut-farming colonel. Lloyd Buckley looked startled. So did the scientists, Carlyle-Macavoy and Kaufman and Elias. The Colonel was pretty startled by it himself.
    “I have another thought,” the Colonel went on, “about their failure so far to attempt any kind of communication with us, and how it reflects on their sense of their relative superiority to us. Speaking now in my academic capacity as a professor of non-western psychology, rather than as a former military man, I want to put forth the point that their refusal to speak with us might not be a function of their ignorance so much as it is a way of making that overwhelming superiority obvious. I mean, how could they not have learned our languages, if they had wanted to? Considering all the other capabilities they obviously have. Races that can travel between the stars shouldn’t have any difficulty decoding simple stuff like Indo-European-based languages. But if they’re looking for a way to show us that we are altogether insignificant to them, well, not bothering to say hello to us in our own language is a pretty good way of doing it. I could cite plenty of precedent for that kind of attitude right out of Japanese or Chinese history.”
    Buckley said to Carlyle-Macavoy, “Can we have some of your thoughts about all this, if you will?”
    “What the Colonel has proposed is an interesting notion, though of course I have no way of telling whether there’s any substance to it. But let me point out this: these aliens appeared in our skies without having given us a whisper of radio noise and not a smidgeon of visual evidence that they were approaching us. Let’s not even mention the various Starguard groups that keep watch for unexpected incoming asteroids. Let’s just consider the radio evidence. Do you know about the SETI project that’s been going on under that and several other names for the last forty or fifty years? Scanning the heavens for radio signals from intelligent beings elsewhere in the galaxy? I happen to be affiliated with one branch of that project. Don’t you think we had instruments looking all up and down the electromagnetic spectrum for signs of alien life at the very moment the aliens arrived? And we didn’t detect a thing until they began showing up on airport radar screens.”
    “So you think there can be a hidden mother ship sitting out there in orbit,” Steele said.
    “It’s perfectly possible that there is. But the main point, as I know Colonel Carmichael will agree, is that the only thing we can say about these aliens for certain at this moment is that they’re representatives of a race vastly more advanced than ourselves, and we had bloody well be
