“That must be quite a load for you to carry, Sire,” Mursk said to him, as starlight broke through the trees.
“Quite,” Bruno agreed. And they finished the walk in silence.
“I don’t know anything about wormholes,” Mursk admitted. “You’re making them? Here?”
Seated once more in his comfortable study, Bruno spread his hands. “Trying to, yes.”
Sensing an appropriate moment, Hugo appeared with a pipe and lighter, which Bruno accepted gratefully.
“Thanks, old thing.”
“You’re entirely welcome,” Hugo answered, sounding truly pleased with himself, albeit that stale, arithmetic sort of pleasure to which emancipated robots were given. “May I walk around the yard a bit?”
“You’re supposed to do as you please, my friend.”
“It pleases me to serve,” Hugo said, and wandered off.
With the ease of much practice, Bruno ignited the home-grown, home-cured weeds in the pipe’s ceramic bowl, and drew a puff of their smoke into his mouth. The natural drugs involved, passing through the tissues of his cheeks and into his bloodstream, were mild and crude and beside the point. It was the anachronism of the act itself that Bruno savored; the loops and whorls of rising smoke connected him to Einstein, to Edison, to all the great thinkers of the Mortal Age, of whom he was the last. Connecting him, indeed, to the fireside musings of primal humanity itself.
“What are they for?” Mursk asked. “You intend these wormholes as a substitute for fax gates?”
“Ideally, yes. There may yet be time to prop up these failing colonies, if I can just—”
“Make it work?”
Bruno laughed around the stem of his pipe. “Yes, make it work. Clever lad. Alas, I fear I’m not up to the task. These old chalkboards are getting white.”
“Eh?”
“Chalkboards. Blackboards. Ah, what do you children know?” The cloud around him thickened with his huffing, and he waved it away. “In the tradition-heavy wilds of Catalonia, where I cut my first set of teeth, the last vestiges of the stone age lingered very nearly until the rise of the Queendom. A chalkboard was a slab of hard, dark slate onto which you would scribble with little cylinders of soft, white chalk. Really! We had one in every classroom, every kitchen. You’d erase the board with a rag, you see, and write in a new batch of lessons or chores or ingredients. But sometimes you’d misplace the rag, and you’d have to scribble around the margins of what you’d already written. If you let this go on long enough, eventually the board would get so white with scribbles that you couldn’t read it anymore. And so we learned: too much knowledge is as bad as none at all. We forget how to forget. But this lesson itself seems to have fallen from our collective memory. Our civilization grows too brilliant to brush its own teeth.
“At any rate, yes, I’m battering my head against this problem, and what progress I’ve made has been more tantalizing than helpful.” Bruno didn’t generally present his works-in-progress—too embarrassing—but in a sudden fit of hospitality he added, “I can show you, if you like.”
“Sure,” Mursk said, shrugging. “It sounds kind of fundamental to our future.”
This irritated Bruno. The lad meant well enough, surely, but a king could grow very tired of his people’s unreasonable expectations. “Only if luck is on our side, lad. The universe is under no obligation to please our petty whims, and I have failed many times to throw a harness round its neck.”
The trick with a pipe was not to puff on it too much, lest its smoke turn sharp and acrid—or too little, lest it fade to the dull flavor of ashes. But Hugo was back again, this time with Bruno’s ashtray, which he whisked onto the desk in front of him before dancing back out of the study again with too-quick, too-perfect fluidity.
“Nice robot,” Mursk said, with less than total conviction.
“He saved my life once, in battle. He’s quite brave.” Bruno set the pipe down in the ashtray and began tapping at his desktop controls. “Now, the first trick in wormhole dynamics is to develop your standing gravity wave very, very rapidly. It’s not at all like collapsing a neuble into a black hole. Second, you’ve got to dump in twice as much power as theory predicts you ought to. I’m still figuring that one out.”
While he spoke, the writing vanished from every surface, zipping into archive space. Glittering green-black bullseyes took their place on two opposite walls. The lights dimmed, and though it wasn’t apparent from here in the windowless study, the sun itself dimmed as well, focusing fully eighty percent of its output in a single strand of violet laser. Bruno’s eastern photovoltaic array, hidden away in a forest glade, took the beam head-on and fed its power directly into the gravity lasers. The air in the study began to shudder, then to twirl itself into fist-sized eddies that popped and lashed their way around the room.
“The third trick,” Bruno said, raising his voice above the hiss, “is to ram a cylindrical mass through the wormhole throat, to stabilize the two openings.” Leaning, he dragged a half-meter iron bar out from under his desk and held it up for Conrad Mursk to see.
“Is this experiment safe?” Mursk wanted to know. The air devils were whipping at his hair, driving him back, blinking and puffing, against the door frame.
“Not particularly,” Bruno called back, “but your image is archived in my fax buffer.”
And then the time for talk was past, for a pair of rippling distortions appeared like lenses in the air between the two men. The spherical wormhole mouths: each displaying a funhouse-mirror view of the photons striking the other. Their instability was apparent even to the naked eye; they wandered and quivered, orbiting one another in a slow spiral that would, within seconds, bring them swirling together in a flash of canceling energy.
Bruno’s initial tests had taken place in vacuum, ten kilometers from Maplesphere and with the trillion-ton mass of the planette between himself and the relativistic action. It was only by accident—literally—that he’d discovered the radiation of a wormhole’s collapse was nonlethal. Or not immediately lethal, anyway; the flux of photons and virtual particles would surely wreak lasting havoc on a body with no access to fax repair.
“Watch!” he instructed, hefting the bar and jabbing it at one of the holes.
There was no preferred direction of travel between the two wormhole mouths; each point on one sphere—or vector through it—corresponded with a point or vector on the other. Bruno’s aim wasn’t bad, but even a glancing blow would have done the trick. The bar slid silently and effortlessly into the nearer sphere, its far end emerging just as cleanly from the other. The two halves of the bar were pointing in wildly different directions, but within moments the two mouths were sliding and rotating into the minimum-energy configuration, wherein the bar was straight. They missed on the first swooping pass, and again on the second, but the oscillations tightened until suddenly the vectors locked.
The spherical distortions vanished. The whirling air devils quieted. The bullseyes faded from Bruno’s walls, and his equations returned, and the lights came back up, and the sun resumed shining, and somewhere in the distance a bird chirped uncertainly.
“Jesus,” Conrad Mursk said.
“Indeed,” Bruno could only agree. He held up the bar for Mursk’s inspection. The two ends were perfectly intact, not damaged in any way, but the distance between them was more than twice what it had been. And the center of the bar…
