“Ninety-nine eight, at a conservative estimate.” Lines of characters began rolling down one of the status screens. “This is what it looks like. I’ve substituted symbols for pulse patterns.”
The captain did not see a pattern, but he accepted Bill’s judgment without question. “You’re saying there’s another ship out here, Bill?”
“I’m saying only that there’s a signal.”
“Where’d it come from?” asked Ava. “Which way?”
“I can’t be sure. But it seemed to originate in the general direction of 1107. The neutron star. Something in orbit, I assume. We passed through the signal too quickly to get a lock on it.”
Langley frowned at the symbols scrolling down the display. He watched until they stopped.
“That’s it,” said Bill. “Do you want me to repeat the record?”
He looked at Ava. She shook her head no.
Langley glanced up at the AI’s image. The face was thin and worn. The gray eminence persona, which Bill usually adopted when things were happening. “Bill, can we find it again?”
The AI hesitated. “A directed signal? If we assume it’s coming from a tighter orbit than ours, we would have to wait until it caught up with us again.”
“How long would that take?”
“Insufficient data.”
“Guess.”
“Probably several months.”
Langley simply didn’t believe it had happened. Not out here. It was more likely to be a glitch somewhere. “Can you make any kind of estimate on the location of the source, Bill?”
“No, Captain. I would need to find it a second time to do that.”
He gazed at Ava. “It’s just a screwup somewhere. Stuff like this happens sometimes. It’s a glitch in the system.”
“Maybe,” she said.
“Bill, run a diagnostic. See if you can find any kind of internal problem that might account for the intercept.”
“I’ve already done that, Captain. Everything seems to be in order.”
Ava’s lids had gone to half-staff. She was peering inside somewhere. “Let’s run it by Pete.” That was Pete Damon, the project director. Pete was the best-known physicist in the world, largely because of his tenure as host of Universe, an extraordinarily popular science series that had done much to win public support for organizations like the Academy, but which had also spurred the jealousy of many of his colleagues.
Langley could hear voices in back, where his passengers were conducting temporal experiments. Although 1107 was only two hundred million years old, it had actually been here well over two billion years. When Ava had tried to explain how that happened, how time moved at a far slower rate at the bottom of the object’s gravity well than it did out here in a less constrained part of the universe, his mind had refused to close around the idea. He knew it was correct, of course, but it gave him a headache to think about it.
Ava brought Pete up on one of the auxiliary screens and conducted a hurried conversation. Pete frowned and shook his head and looked at his own displays. “Can’t be,” he said.
“You want to ignore it?” asked Ava.
More glances at displays. Whispered conversations with shadowy figures off to one side. Fingertips tapping on a console. “No,” he said. “I’m on my way up.”
Hatches opened and closed. Langley heard footsteps and excited voices. “Sounds as if you stirred up the natives, Ava,” he said.
She looked happy. “I’m not surprised.”
Several of them spilled out onto the bridge. Pete. Rick Stockard, the Canadian. Hal Packwood, who was on his first long flight and who drove everybody else crazy talking endlessly about the wonder of it all. Miriam Kapp, who was running the chrono experiments. And two or three more. Everybody was breathing hard.
“Where’d it come from?” The question came from every side. “Did we really hear something?”
“Are we still picking it up?”
“For God’s sake, Mike,” said Tora Cavalla, an astrophysicist with a substantial appetite for sex, “are we scanning for the source? You realize somebody might be out there?”
“We are,” said Langley. He didn’t care for Tora very much. Her behavior disrupted the ship, and she seemed to think everyone around her was an idiot. It was an attitude that might have passed unnoticed at, say, CalTech. But in the intimate environment of a superluminal, where people had to live together for months at a time, she created claustrophobia and jealousy. “Of course we’re looking. But don’t expect much. We’ve no idea where the source might have been. And any kind of scan near that pile of iron is suspect. The gravity well distorts everything.”
“Keep looking,” said Packwood, speaking as if he were in charge.
“Is there any other likely explanation?” Tora asked. Her wide white brow was furrowed. She was really intrigued by the event.
“There’s always the possibility of an equipment malfunction. But Bill says no.”
She glanced over at Pete, her gray eyes pleading for him to turn the mission into a hunt for the signal.
“This isn’t something,” Pete said, “that we want to write off until we have an idea what caused the transmission.” He was tall, long-legged, solemn. His eyes were furtive, always suggesting he was hiding something. Langley thought he looked like a pickpocket who’d made good. But he kept his word. You could believe what he said. “What have you actually got, Mike?” he asked.
“It was a one-shot intercept. But Bill can’t give us any more than that.”
“Can we hear it?” asked Packwood.
“Bill,” Langley said, “run the record. Audio this time.”
It was about two seconds long, a series of high-pitched blips and squiggles. “We can’t read any of it?” asked Pete.
“No,” said Langley. “Zero.”
The team members looked at one another solemnly. A couple more pushed in. “It has to mean there’s another ship here somewhere,” Pete said. “Or an orbiter.”
“Nothing of ours out here,” said a quiet, very young, female technician who had just come in. Her name was Wanda. “I double-checked.”
Pete nodded.
“What would anybody be doing here?” asked Tora.
“We’re here,” said Langley.
Tora shook her head. “Sensors aren’t picking up anything?”
Langley had already checked the stat board. But he looked again. It was still quiet.
“If there were something out there,” said Stockard, “I’d think we’d be able to see it.” He was gruff, aggressive. A man who, in another age, would have been career military.
“Well,” said Packwood, “conditions tend to be strange in a place like this. Space folded over on itself, time warps blinking in and out. Still—”
“Why don’t we turn around and go back?” said Pete. “Search the same area?”
“Can’t. We can’t spare the fuel for a U-turn. If you want to get back to the same spot, you’ll have to wait until we go around again.”
“How long?”
“Several months.”
They all looked at him, but there wasn’t anything he could do. Langley didn’t think anything out of the ordinary was happening anyhow. He’d been carrying Academy teams into deep space for almost forty years, and he knew if there was one thing about neutron stars a man could be sure of, it was that nobody else was hanging around.
In all the time since the superluminals had left Earth, they’d found only one other living civilization, if you could call it that. The inhabitants of Nok went back about fourteen thousand years, but they were just now coming out of their industrial revolution. They were strong believers in various causes, and they were constantly at war with one another.
There’d been ruins in a few other places. But that was it. Langley had personally seen upward of a thousand terrestrial worlds, and there weren’t thirty that supported any kind of life whatever. And two-thirds of those were single-celled.
No. Whatever Bill had intercepted, or thought he’d intercepted, the explanation would not include a vessel crewed by something from another world. But it was easy enough to understand the excitement of his passengers.
