He glanced out at the city, shrugged with his eyebrows, looked at the three of them again.
“So you might imagine it got our attention when Audra Nash came to us in 1986 and said she had an idea. A way to broadcast ELF using satellites. If it were almost any other person—much less a student—the committee wouldn’t have even taken the meeting. But Miss Nash had some credibility to back up her claim. Her work as a grad student had already influenced the design of next-gen communications satellites. She was smart as hell, and she knew the field better than probably anyone. What she wanted from us was access to the results of all the ELF research over the years, all the raw data from the experiments in directing it, focusing it. We barely had to think about it. First, the data wasn’t all that sensitive. It was just a detailed list of all the things that didn’t work. And all the countries out there who could possibly want to steal it didn’t need to: they already had the same data, based on their own failures. Second, we thought her idea might actually have merit. She was brilliant, she had a track record, and she was coming to this problem with fresh eyes. The concept she had in mind was certainly different enough. We hadn’t tried anything like it in all our efforts.”
“But how could it work at all?” Bethany said. “Just basic physics should make it impossible for a satellite. A transmitter has to be big enough to handle the wavelengths it generates, and ELF waves are huge. Hundreds of miles long.”
Garner nodded. “Her idea was radical. I don’t pretend to have understood it in detail, but essentially it was this: ELF waves occur naturally in the Earth’s atmosphere. The sun radiates them, and lightning strikes produce them, too. It’s all random, of course. All noise, no signal. And even if the frequencies that affect people happen to appear, they’re drowned out in the clutter and nothing happens. Audra Nash believed a satellite, transmitting much shorter wavelengths with the right precision, could cancel out certain frequencies of natural ELF over a given target area. Could allow us to pick and choose which frequencies to cancel out . . . and which to leave intact.” He looked at Bethany. “So you’re right. A satellite can’t broadcast ELF, but in theory it could disrupt it where it naturally occurs, and whittle away everything but the useful ranges. At which point, they would certainly affect people. And it would be precisely targetable. You could influence a few blocks. Or a whole city. Or an area much, much larger than that.”
No one said anything. They waited.
“So we gave her the go-ahead,” Garner said. “Gave her access to everything we had. She dove into it. Lived and breathed it. She came back before the committee six months later. With a blueprint.”
“Did anyone build it?” Paige said.
“Nope.”
Paige looked confused. “Why not?”
“Because it was still a long shot. Even with a good blueprint there’s trial and error, details to hammer out in the prototype. That can be expensive even if you’re modifying a Humvee. For a satellite, tack on a couple zeroes.”
“Come on,” Travis said. “The hubcaps on the stealth bomber probably cost a million apiece. Since when does the Pentagon get sticker shock?”
Garner smiled. “There’s another reason, but it’s even less believable.” He considered how to frame it. “It’s like this. In the early days, when everyone was looking for a straightforward way to weaponize this technology, there was an urgency to figure it out. Get it before the other guys. That makes sense if you think there’s some big, obvious solution out there, the kind that everyone will eventually stumble onto. But Audra’s idea wasn’t like that. It was obscure as hell, based on an overlap of knowledge probably no one but she had. There was a good chance that nobody else in the world would ever come up with it. But they’d be more than happy to copy ours, if we went ahead with the project. You hear people talk about the atomic genie coming out of the bottle in 1945. Like if we didn’t let it out, nobody ever would have. It’s probably not true. Fission’s not exactly an unheard-of concept. But Audra’s satellite design was. And we just thought . . . why do it? Why bring the world into an age defined by something like this? So we sat on it. Locked the design away. Audra understood, though I’m sure she was disappointed. She got out of the design game after that. Went off to Harvard, got her other doctorate in philosophy, got into relief work. Married Finn. I didn’t hear about her again until 1995, when that little dustup happened with the paper those two tried to publish.”
Paige had been looking at the floor. She looked up now. “Did you see a copy of it?”
