Pebble in the Sky by Isaac Asimov

plain? He wants to be allowed to prove that Earth
is
the original home of Humanity. He wants to bring scientific authority to the aid of subversion.”
    “Then stop him.”
    “I can’t. There you have it, frankly. There’s a theory about that viceroys can do anything, but that just isn’t so. That man, Arvardan, has a writ of permission from the Bureau of Outer Provinces. It is approved by the Emperor. That supersedes me completely. I could do nothing without appealing to the Central Council, and that would take months. . . . And what reasons could I give? If I tried to stop him by force, on the other hand, it would be an act of rebellion; and you know how ready the Central Council is to remove any executive they think is overstepping the line, ever since the Civil War of the eighties. And then what? I’d be replaced by someone who wouldn’t be aware of the situation at all, and Arvardan would go ahead anyway.
    “And that
still
isn’t the worst, Flora. Do you know how he intends to prove the antiquity of Earth? Suppose you guess.”
    Flora laughed gently. “You’re making fun of me, Ennius. How should I guess? I’m no archaeologist. I suppose he’ll try to dig up old statues or bones and date them by their radioactivity or something like that.”
    “I wish it were like that. What Arvardan intends to do, he told me yesterday, is to enter the radioactive areas on Earth. He intends to find human artifacts there, show that they exist from a time previous to that at which Earth’s soil became radioactive—since he insists the radioactivity is man-made—and date it in that fashion.”
    “But that’s almost what I said.”
    “Do you know what it means to enter the radioactive areas? They’re Forbidden. It’s one of the strongest Customs these Earthmen have. No one can enter the Forbidden Areas, and all radioactive areas are Forbidden.”
    “But then that’s good. Arvardan will be stopped by the men of Earth themselves.”
    “Oh, fine. He’ll be stopped by the High Minister! And then how will we ever convince him that all this was not a Government-sponsored project, that the Empire is not conniving at deliberate sacrilege?”
    “The High Minister can’t be that touchy.”
    “Can’t he?” Ennius reared back and stared at his wife. The night had lightened to a slatiness in which she was just visible. “You have the most touching naïveté. He certainly
can
be that touchy. Do you know what happened—oh, about fifty years ago? I’ll tell you, and then you can judge for yourself.
    “Earth, it so happens, will allow no outward sign of Imperial domination on their world because of their insistence that Earth is the rightful ruler of the Galaxy. But it so happened that young Stannell II—the boy emperor who was somewhat insane and who was removed by assassination after a reign of two years; you remember!—ordered that the Emperor’s insignia be raised in their Council Chamber at Washenn. In itself the order was reasonable, since the insignia is present in every planetary Council Chamber in the Galaxy as a symbol of the Imperial unity. But what happened in this case? The day the insignia was raised, the town became a mass of riots.
    “The lunatics of Washenn tore down the insignia and took up arms against the garrison. Stannell II was sufficiently mad to demand that his order be complied with if it meant the slaughter of every Earthman alive, but he was assassinated before that could be put into effect, and Edard, his successor, canceled the original order. All was peace again.”
    “You mean,” said Flora incredulously, “that the Imperial insignia was not replaced?”
    “I mean that exactly. By the Stars, Earth is the only one of the millions and millions of planets in the Empire that has no insignia in its Council Chamber. This miserable planet we are on now. And if even today we were to try again, they would fight to the last man to prevent us. And you ask me if they’re touchy. I tell you
