 Which is not true about why Crownwall was able to travel to Vega undetected?
The sight of an Earthman on Vega III, where it was impossible for an outlander to be, brought angry crowds to surround John Crownwall as he strode toward the palace of Viceroy Tronn Ffallk, ruler of Sector XII of the Universal Holy Empire of Sunda. If they carried out the threats of their present attitude, Earth would have to send Marshall to replace him. Instantly, and unexpectedly to Crownwall, the threatening crowd dropped back fearfully, so that he walked the last fifty meters alone. A pair of guards, their purple hides smoothly polished and gleaming with oil, crossed their ceremonial pikes in front of him as he approached the entrance. "Just tell him that a man has arrived from Earth to talk to him. Behind him stood a heavy and pompous appearing Vegan in lordly trappings. "It was only decided yesterday, back on Earth, that I would be the one to make the trip here. Even if you could spy through buildings on Earth from space, which I doubt, your communications system can't get the word through that fast." What I meant was that I expected someone from Earth to break through our blockade and come here. Still, if you were on your home planet only yesterday, that's astonishing even to me. "If you wanted someone from Earth to come here to see you, why did you put the cordon around Earth? And why did you drop a planet-buster in the Pacific Ocean, and tell us that it was triggered to go off if we tried to use the distorter drive? But you did come, so I can tell you that although I am the leader of one of the mightiest peoples in the Galaxy, whereas there are scarcely six billions of you squatting on one minor planet, we still need each other. When you showed up in the spaceways, it was decreed that you had to be stopped at once. There was even serious discussion of destroying Earth out of hand, while it is still possible. While these creatures could by no means be classed among the intelligent races, there was a general expectation, which we reported to the Sunda, that they would some day come to be numbered among the Servants of the Emperor. So we let you alone, in order that you could develop in your own way, until you reached a high enough civilization to be useful—if you were going to. As an Earthling, you have heard of the details of the first expedition of your people into space, of course?" " Heard about it?" exclaimed Crownwall.
 He traveled into the future so as to not need to experience the distance travel himself
 He was not technically moving through space in a typical sense  He employed technology unfamiliar to the Vegans  His ship's drive does not give off the usual traceable signals  He traveled into the future so as to not need to experience the distance travel himself
