gathering in strength, until they fell to the ground here and now, around her.

“The problem is,” Cornelius said gently, “Feynman’s argument, if you think about it, rests on assumptions about the distribution of matter in the future of the universe. You have to suppose that every photon leaving our transmitters will be absorbed by matter somewhere — maybe in billions of years from now. But what if that isn’t true? The universe isn’t some cloud of gas. It’s lumpy, and it’s expanding. And it seems to be getting more transparent.”

“We thought it was possible,” Dan said, “that not all the advanced waves cancel out perfectly. Hence all this. We use the radio dishes here to send millisecond-pulse microwave radiation into space. Then we vary the rig: we send out pulses into a deadend absorber. And we monitor the power output. Remember the advanced waves are supposed to contribute to the energy of the retarded wave, by Feynman’s theory. If the universe isn ‘t a perfect absorber—”

“Then there would be a difference in the two cases,” Emma said.

“Yeah. We ought to see a variation, a millisecond wiggle, when we beam into space, because the echo effect isn’t perfect. And we hope to detect any message in those returning advanced echoes — if somebody downstream has figured out a way to modify them.

“We pick cloudless nights, and we aim out of the plane of the Galaxy, so we miss everything we can see. We figure that only one percent of the power will be absorbed by the atmosphere, and only three percent by the Galaxy environment. The rest ought to make it — spreading out, ever more thinly — to inter-galactic space.”

“Of course,” Cornelius said, “we can be sure that whatever message we do receive will be meaningful to us.” He looked around; his skin seemed to glow in the starlight. “I mean, to the four of us, personally. For they know we are sitting here, planning this.”

Emma shivered again. “And did you find anything?”

“Not to a part in a billion,” Cornelius said.

There was silence, save for a distant wind rustling ink-black trees.

Emma found she had been holding her breath. She let it out gently. Of course not, Emma. What did you expect?

“Crying shame,” Dan Ystebo said, and he reached for another beer. “Of course experiments like this have been run before. You can find them in the literature. Schmidt in 1980. Partridge, Newman a few years earlier. Always negative. Which is why,” he said slowly, “we’re considering other options.”“

“ What other options?” Emma asked.

“We must use something else,” Cornelius said, “something that isn’t absorbed so easily as photons. A long mean-free-path length. Neutrinos.”

“The spinning ghosts.” Dan belched, and took a pull at his beer. “Nothing absorbs neutrinos.”

Emma frowned, only vaguely aware of what a neutrino was. “So how do you make a neutrino transmitter? Is it expensive?”

Cornelius laughed. “You could say that.” He counted the ways on his hands. “You set off a new Big Bang. You spark off a supernova explosion. You turn a massive nuclear power plant on and off. You create a high-energy collision in a particle accelerator…”

Malenfant nodded. “Emma, I was going to tell you. I need you to find me an accelerator.”

Enough, she thought.

Emma stood and drew Malenfant aside. “Malenfant, face it. You’re being spun a line by Cornelius here, who has nothing to show you, nothing but shithead arguments based on weird statistics and games with techno toys. He’s spinning some kind of schizoid web, and he’s drawing you into it. It has to stop here before—”

“If something goes wrong in the cockpit,” he snapped, “you don’t give up. You try something else. And then another thing. Again and again until you find something that works. Have a little faith, Emma.” Emma opened her mouth, but he had already turned back to Dan Ystebo. “Now tell me how we detect these damn neutrons.”

“Neutrinos, Malenfant.”

Cornelius leaned over to Emma. “The Feynman stuff may seem spooky to you. It seems spooky to me: the idea of radio waves passing back and forth through time. But it’s actually fundamental to our reality.

“Why is there a direction to time at all? Why does the future feel different from the past? Some of us believe it’s because the universe is not symmetrical. At one end there is the Big Bang, a point of infinite compression. And at the other there is the endless expansion, infinite dilution. They couldn’t be more different.

“ We can figure out the structure to the universe by making observations, expressing it in such terms. But what difference does it make to an electron? How does it know that the forward-in-time radio waves are the correct ones to emit?

“Maybe it’s because of those back-in-time echoes. Perhaps an electron can tell where it is in time — and which way it’s facing. And that s how come the forward-in- time waves are the ones that make sense.

“All this is analogy and anthropomorphism. Of course electrons don’t know anything. I could say, more formally, that the Feynman theory provides a way for the boundary conditions of the universe to impose a selection effect on retarded waves. But that would just be blinding you with science; and we wouldn’t want that, would we?” He was smiling, his teeth white. He was toying with her, she realized.

Malenfant and Ystebo talked on, slightly drunk, eager. It seemed to Emma that their voices rose up into the sky, small and meaningless, and far above the stars wheeled, unconcerned.

Bill Tybee:

Tuesday.

Well, June, I had my meeting with Principal Bradfield. She’s still determined she won’t take Tom back.

At least I found out a little more.

Tom, well, he isn’t the only one. The only supersmart kid, I mean. There are three others they’ve identified at the school, and a couple more they’re suspicious about. That makes it a couple per thousand, and that’s about right.

It seems this is some kind of nationwide phenomenon. Maybe global.

But the numbers are uncertain. The kids are usually identified only when they get to school.

The principal says they are disruptive. If you have one of them in a class she gets bored and impatient and distracts everybody else. If there is more than one, they kind of hook up together and start doing their own projects, even using their own private language, the principal says, until you can’t control them at all.

And then there’s the violence. The principal wasn’t about to say so, but I got the impression some of the teachers aren’t prepared to protect the kids properly.

I asked the principal, why us? But she didn’t have an answer.

Nobody knows why these kids are emerging. Maybe some environmental thing, or something in the food, or some radiation effect that hit them in the womb. It’s just chance it happened to be us.

Anyhow the school board is looking at some other solution for Tom. Maybe he’ll have a teacher at home. We might even get an e-teacher, but I don’t know how good they are. I did read in the paper there have been proposals for some kind of special schools just for the smart kids, but that wouldn’t be local; Tom would have to board.

Anyhow I don’t want Tom to be taken off to some special school, and I know you feel the same.

I want him to be smart. I’m proud that he’s smart. But I want him to be normal, just like other kids. I don’t want him to be different.

Tom wants me to download some of the stuff from his Heart for you. Just a second…

Emma Stoney:

Back in her Vegas office, Emma sat back and read through her

latest submission to Maura Della.

The antique treaties that govern space activities are examples of academic lawmaking. They were set down far in advance of any activity they were supposed to regulate. They certainly fail to address the legitimate needs of private corporations and individuals who might own space-related resources and/or exploit them for profit. In fact they are more political statements by the former Soviet Union and Third World nations than a workable set of legal rules.

We believe the most appropriate action is therefore to get our ratification of the treaties revoked. There are precedents for this, notably when President Carter revoked the Panama Canal Treaty by an executive order. And to put it bluntly, since the United States signed these treaties with a single main competitor in mind — the Soviet Union, a competitor which no longer even exists — there is no reason to be morally bound by them…

Malenfant was picking a fight by building his damn spaceship, out in the desert, exposing it to the cameras, and daring the bureaucrats and turf warriors and special- interest groups to shut him down. That boldness had carried him a long way. But Emma suspected that Malenfant had had an easy ride so far; the bureaucratic infighting had barely begun.

Emma — with a team of specialist lawyers mostly based in New York, and with backing from Maura and other friends in Washington — was trying to clear away the regulatory issues that could ground Malenfant’s BDBs just as surely as a blowup on

the pad.

Space activities were regulated, internationally, by various treaties that dated back to the Stone Age of spaceflight: days when only governments operated spacecraft, treaties drafted in the shadow of the Cold War. But the mass of badly drafted legislation and treaties gave rise to anomalies and contradictions.

Consider tort liabilities, for instance. If Malenfant had been operating an airline, and one of his planes crashed on Mexico, then he would be responsible and his insurance would have to soak up the damages and lawsuits. But under the terms of a 1972 space liability convention, if Malenfant’s BDB crashed, the U.S. government itself would be liable.

Another problem area was the issue of certification of airworthiness — or maybe spaceworthiness — of Malenfant’s BDBs. Every aircraft that crossed an international border was supposed to carry a certificate of airworthiness from its country of registry, a certificate of manufacture, and a cargo manifest. So was a BDB an air vehicle? Federal aviation regulations actually contained no provisions for certificating a space vehicle. When she’d dug into the records she’d found that the FAA — the Federal Aviation Administration — had dodged the issue regarding the space shuttle when, in 1977, it had ruled that the shuttle orbiter was not an aircraft, despite being a winged vehicle that glided home.

It was a mess of conflicting and unreasonable regulations, at national and international levels. Maybe it was going to take a bullheaded operator like Malenfant to break through this thicket.

And all that just concerned the operation of a private spacecraft. When Malenfant reached his asteroid, there would be a whole different set of problems to tackle.

Malenfant didn’t want to own the asteroid; he just wanted to make money out of it. But it wasn’t clear how he could do even that.

Malenfant was arguing for a system that could enforce private property rights on the asteroid. The patent and property registry of a powerful nation — specifically the United States — would be sufficient. The claims would be enforceable internationally by having the U.S. Customs Office penalize any import that was made to the United States in defiance of such a claim. This mechanism wouldn’t depend on the United States, or anybody else, actually claiming sovereignty over the rock. There was actually a precedent: the opening up of trans-Appalachian America in the seventeenth century, long before any settler got there, under a system of British Crown land patents.

But the issue was complex, disputatious, drowned in ambiguous and conflicting laws and treaties.

Unutterably wearying.

She got up from her desk and poured herself a shot of tequila, a particular weakness since her college days. The harsh liquid seemed to explode at the back of her throat.

Did she actually believe all this? Did she think it was right! Did the United States have the moral authority unilaterally to hand out off-world
