Ender's Game (Ender Wiggins Saga)

in fact, is that most bugger soldiers are females, but with atrophied or vestigial sexual organs. We can't tell. It's their psychology that would be most useful to you, and we haven't exactly had a chance to interview them.”
      "Tell me what you know, and maybe I'll learn something that I need.”
      So Graff told him. The buggers were organisms that could conceivably have evolved on Earth, if things had gone a different way a billion years ago. At the molecular level, there were no surprises. Even the genetic material was the same. It was no accident that they looked insectlike to human beings.   Though their internal organs were now much more complex and specialized than any insects, and they had evolved an internal skeleton and shed most of the exoskeleton, their physical structure still echoed their ancestors, who could easily have been very much like Earth's ants. "But don't be fooled by that," said Graff. "It's just as meaningful to say that our ancestors could easily have been very much like squirrels.”
      "If that's all we have to go on, that's something ," said Ender.
      "Squirrels never built starships," said Graff. "There are usually a few changes on the way from gathering nuts and seeds to harvesting asteroids and putting permanent research stations on the moons of Saturn.”
      The buggers could probably see about the same spectrum of light as human beings, and there was artificial lighting in their ships and ground installations. However, their antennae seemed almost vestigial. There was no evidence from their bodies that smelling, tasting, or hearing were particularly important to them. "Of course, we can't be sure. But we can't see any way that they could have used sound for communication. The oddest thing of all was that they also don't have any communication devices on their ships. No radios, nothing that could transmit or receive any kind of signal.”
      "They communicate ship to ship. I've seen the videos, they talk to each other.”
      "True. But body to body, mind to mind. It's the most important thing we learned from them. Their communication, however they do it, is instantaneous. Lightspeed is no barrier. When Mazer Rackham defeated their invasion fleet, they all closed up shop. At once. There was no time for a signal. Everything just stopped.”
      Ender remembered the videos of uninjured buggers lying dead at their posts.
      "We knew then that it was possible to communicate faster than light. That was seventy years ago, and once we knew it could be done, we did it. Not me , mind you, I wasn't born then.”
      "How is it possible?”
      "I can't explain philotic physics to you. Half of it nobody understands anyway. What matters is we built the ansible. The official name is Philotic Parallax Instantaneous Communicator, but somebody dredged the name ansible out of an old book somewhere and it caught on. Not that most people even know the machine exists.”
      "That means that ships could talk to each other even when they're across the solar system," said Ender.
      "It means," said Graff, "that ships could talk to each other even when they're across the galaxy. And the buggers can do it without machines.”
      "So they knew about their defeat the moment it happened," said Ender. "I always figured -- everybody always said that they probably only found out they lost the battle twenty five years ago.”
      "It keeps people from panicking," said Graff. "I'm telling you things that you can't know, by the way, if you're ever going to leave I.F. Command. Before the war's over.”
      Ender was angry. "If you know me at all, you know I can keep a secret.”
      "It's a regulation. People under twenty-five are assumed to be a security risk. It's very unjust to a good many responsible children, but it helps narrow the number of people who might let something slip.”
      "What's all the secrecy for, anyway?”
      "Because we've taken some terrible risks, Ender, and we don't want to have every net on earth second-guessing those decisions. You see, as soon as we had a working ansible, we tucked it into our best starships and launched them to attack the buggers home systems.”
      "Do we know where they are?”
      "Yes.”
      "So we're not waiting for the Third Invasion.”
      "We are the Third Invasion.”
      "We're attacking them. Nobody says that. Everybody thinks we have a huge fleet of warships waiting in the comet shield--”
      "Not one. We're quite defenseless here.”
