That was when he felt it, in his body: they were really here.
From the beginning Roger had a hand—a heavy, guiding hand—in the design of the ship. Not for nothing had he learned the Lab’s doctrine of dual use. Not for nothing had he cultivated Kakopoulos’s acquaintance. Every feature that fitted the ship for interstellar space was a plausible choice for Kak’s purpose: hibernators, cosmic-ray shielding, nuclear rocket, hardened computers, plutonium pile and Stirling engine .
In the weeks prior to departure, they moved the ship to a more distant orbit, too distant for Kak’s X-33 to reach. There they jettisoned quite a bit of the ship’s interior. They added their fusion engine, surrounded the vessel with fuel sleds, secured anti-proton traps, stowed the magsail, loaded the seed bank and a hundred other things .
They were three hundred AU out from Alpha Centauri. Velocity was one-thousandth c. The magsail was programmed to run for two more years, slowing them by half again. But lately their deceleration had shown variance. The magsail was running at higher current than planned. Very close to max spec. That wasn’t good. Logs told him why, and that was worse.
He considered options, none good. The sail was braking against the interstellar medium, stray neutral atoms of hydrogen. No one knew for sure how it would behave once it ran into Alpha’s charged solar wind. Nor just where that wind started. The interstellar medium might already be giving way to it. If so, the count of galactic cosmic rays would be going down and the temperature of charged particles going up.
He checked. Definitely maybe on both counts.
He’d never liked this plan, its narrow margins of error. Not that he had a better one. That was the whole problem: no plan B. Every intricate, fragile, untried part of it had to work. He’d pushed pretty hard for a decent margin of error in this deceleration stage and the subsequent maneuvering in the system—what a tragedy it would be to come to grief so close, within sight of shore—and now he saw that margin evaporating.
Possibly the sail would continue to brake in the solar wind. If only they could have tested it first.
Zia didn’t trust materials.Or, rather: he trusted them to fail. Superconductors, carbon composite, silicon, the human body. Problem was, you never knew just how or when they’d fail.
One theory said that a hydrogen wall existed somewhere between the termination shock and the heliopause, where solar wind gave way to interstellar space. Three hundred AU put Gypsy in that dicey zone.
It would be prudent to back off the magsail current. That would lessen their decel, and they needed all they could get, they had started it too late, but they also needed to protect the sail and run it as long as possible.
Any change to the current had to happen slowly. It would take hours or possibly days. The trick was not to deform the coil too much in the process, or create eddy currents that could quench the superconducting field.
The amount of power he had available was another issue. The plutonium running the Stirling engine had decayed to about half its original capacity.
He shut down heat in the cabin to divert more to the Stirling engine. He turned down most of the LED lighting, and worked in the semidark, except for the glow of the monitor. Programmed a gentle ramp up in current.
Then he couldn’t keep his eyes open.
At Davos, he found himself talking to an old college roommate. Carter Hall III was his name; he was something with the UN now, and with the Council for Foreign Relations—an enlightened and condescending asshole. They were both Harvard ‘32, but Hall remained a self-appointed Brahmin, generously, sincerely, and with vast but guarded amusement, guiding a Sudra through the world that was his by birthright. Never mind the Sudra was Muslim .
From a carpeted terrace they overlooked a groomed green park. There was no snow in town this January, an increasingly common state of affairs. Zia noted but politely declined to point out the obvious irony, the connection between the policies determined here and the retreat of the snow line .
Why Zia was there was complicated. He was persona non grata with the ruling party, but he was a scientist, he had security clearances, and he had access to diplomats on both sides of the border. India had secretly built many thousands of microfusion weapons and denied it. The US was about to enter into the newest round of endless talks over “nonproliferation, “ in which the US never gave up anything but insisted that other nations must .
Hall now lectured him. India needed to rein in its population, which was over two billion. The US had half a billion .
Zia, please, look at the numbers. Four-plus children per household just isn’t sustainable .
Abruptly Zia felt his manners fail .
Sustainable? Excuse me. Our Indian culture is four thousand years old, self-sustained through all that time. Yours is two, three, maybe five hundred years old, depending on your measure. And in that short time, not only is it falling apart, it’s taking the rest of the world down with it, including my homeland .
Two hundred years, I don’t get that, if you mean Western—
I mean technology, I mean capital, I mean extraction .
Well, but those are very, I mean if you look at your, your four thousand years of, of poverty and class discrimination, and violence—
Ah? And there is no poverty or violence in your brief and perfect history? No extermination? No slavery?
Hall’s expression didn’t change much .
We’ve gotten past all that, Zia. We—
Zia didn’t care that Hall was offended. He went on:
The story of resource extraction has only two cases, okay? In the first case, the extractors arrive and make the local ruler an offer. Being selfish, he takes it and he becomes rich—never so rich as the extractors, but compared to his people, fabulously, delusionally rich. His people become the cheap labor used to extract the resource. This leads to social upheaval. Villages are moved, families destroyed. A few people are enriched, the majority are ruined. Maybe there is an uprising against the ruler .
In the second case the ruler is smarter. Maybe he’s seen some neighboring ruler’s head on a pike. He says no thanks to the extractors. To this they have various responses: make him a better offer, find a greedier rival, hire an assassin, or bring in the gunships. But in the end it’s the same: a few people are enriched, most are ruined. What the extractors never, ever do in any case, in all your history, is take no for an answer .
Zia, much as I enjoy our historical discussions—
Ah, you see? And there it is—your refusal to take no. Talk is done, now we move forward with your agenda .
We have to deal with the facts on the ground. Where we are now .
Yes, of course. It’s remarkable how, when the mess you’ve made has grown so large that even you must admit to it, you want to reset everything to zero. You want to get past “all that.” All of history starts over, with these “facts on the ground.” Let’s move on, move forward, forget how we got here, forget the exploitation and the theft and the waste and the betrayals. Forget the, what is that charming accounting word, the externalities. Start from the new zero .
Hall looked weary and annoyed that he was called upon to suffer such childishness. That well-fed yet kept-fit form hunched, that pale skin looked suddenly papery and aged in the Davos sunlight .
You know, Zia prodded, greed could at least be more efficient. If you know what you want, at least take it cleanly. No need to leave whole countries in ruins .
