The Mote in God's Eye - Larry Niven [28]
Rod took a moment to answer Sally’s call. “Make it fast, Sally. If you please. We’re under battle conditions.”
“Yes, Rod, I know. May I come to the bridge?”
“Afraid not. All seats occupied.”
“I’m not surprised. Rod, I just wanted to remind you of something. Don’t expect them to be simple.”
“I beg your pardon?”
“Just because they don’t use Alderson Drive, you’ll expect them to be primitive. Don’t. And even if they were primitive, primitive doesn’t mean simple. Their techniques and ways of thought may be very complex.”
“I’ll keep it in mind. Anything else? OK, hang on, Sally. Whitbread, when you’ve got no other duties, let Miss Fowler know what’s going on,” He closed the intercom from his mind and looked at the stern screen even as Staley shouted.
The intruder’s light sail was rippling. Reflected light ran across it in great, ponderous, wavy lines. Rod blinked but it didn’t help; it is very difficult to see the shape of a distorted mirror. “That could be our signal,” Rod said. “They’re using the mirror to flash—”
The glare became blinding, and all the screens on that side went dead.
The forward scanners were operative and recording. They showed a wide white disc, the star New Caledonia, very close, and approaching very fast, 6 percent of the velocity of light; and they showed it with most of the light filtered away.
For a moment they also showed several odd black silhouettes against that white background. Nobody noticed, in that terrible moment when MacArthur was burned blind; and in the next moment the images were gone.
Kevin Renner spoke into the stunned silence: “They didn’t have to shout,” he complained.
“Thank you, Mr. Renner,” Rod said icily. “Have you other, perhaps more concrete suggestions?”
MacArthur was moving in erratic jolts, but the light sail followed her perfectly. “Yes, sir,” Renner said. “We’d do well to leave focus of that mirror.”
“Damage control, Captain,” Cargill reported from his station aft. “We’re getting a lot of energy into the Field. Too much and damned fast, with none of it going anywhere. If it were concentrated it would burn holes in us, but the way it washes across, we can hold maybe ten minutes.”
“Captain, I’ll steer around behind the sail,” Renner said. “At least we’ve got sun-side scanners, and I can remember where the pod was—”
“Never mind that. Take us through the sail,” Rod ordered.
“But we don’t know—”
“That was an order, Mr. Renner. And you’re in a Navy ship.”
“Aye aye, sir.”
The Field was brick red and growing brighter; but red wasn’t dangerous. Not for a while.
As Renner worked the ship, Rod said casually, “You may be assuming the aliens are using unreasonably strong materials. Are you?”
“It’s a possibility, sir.” MacArthur jolted; she was committed now. Renner seemed to be bracing himself for a shock.
“But the stronger the materials are, Mr. Renner, the thinner they will spread them, so as to pick up the maximum amount of sunlight for the weight. If they have very strong thread they will weave it thin to get more square kilometers per kilo, right? Even if meteors later get a few square km of sail, well, they still made a profit, didn’t they? So they’ll make it just strong enough.”
“Yes, sir,” Renner sang. He was driving at four gees, keeping Cal directly astern; he was grinning like a thief, and he was no longer bracing himself for the crash.
Well, I convinced him, Rod thought; and braced himself for the crash.
The Langston Field was yellow with heat.
Then, suddenly, the sunward scanners showed black except for the green-hot edge of MacArthur’s own Field, and a ragged blazing silhouette of white where MacArthur had ripped through the intruder’s sail.
“Hell, we never felt it!” Rod laughed. “Mr. Renner. How long before we impact the sun?”
“Forty-five minutes, sir. Unless we do something about it.”
“First things first, Mr. Renner. You keep us matched up with the sail, and right here.” Rod activated another circuit to reach the Gunnery Officer. “Crawford! Put some light on that sail and see if you can find the shroud connections. I want you to
