Runyan knew that he should go immediately to the computer room, but he was confident that his people would have everything under control, and he wanted a last look. As he made his way through the corridors, he noticed how empty they felt. The platform had hustled with a thousand souls for a year, but now was down to a skeleton crew. He stepped into the central dome. The wave of dial TO was stronger than ever, amplified by the tension of this last morning. The device which loomed in the centre of the room was more polished, but resounded with echoes of the machine Paul Krone had constructed which had brought them to this pass — a hedgehog array of gigantic lasers all focused into a central chamber where the hole would make its appearance in a little over two hours.
Unlike Krone's original, this one was designed not to create and support, but to track and destroy. It was mounted on powerful hydraulic gimbals which allowed it to lift and settle, rotate and track. Each laser was individually aimed, controlled through an elaborate computer-driven feedback process. Although it weighed hundreds of tons and should have been ponderous, it was quick as a gun— fighter. Runyan watched in awe as the device was put through its final paces, leaping and slurring with blurring speed. In principle it could follow the hole even though the platform were buffeted by gale force winds. This day was carefully chosen, however, the weather monitored for weeks, and all the device needed to do was follow a simple parabolic trajectory. Runyan shook his head as one would at the imminent death of a magnificent animal.
He left the dome and descended to the computer complex. He paused inside the door of the operations room and glanced through the window of the cubicle where the central computer stood. It was not much bigger than two men back-to-back, but was the state of the art parallel processing machine. In turn, it communicated with twenty— odd smaller dedicated machines scattered about the platform. Runyan made a silent tour of the room, pausing behind each of the half dozen operators at their terminals who made final crosschecks before turning the whole operation over to the central computer. Signals from special seismic and sonar monitoring stations throughout the world were fed by satellite relay, so the computer could register the location of the hole instant by instant. Any perturbation in the orbit was translated into a signal to the powerful turbines in the bowels of the platform. These could drive the platform at a maximum speed of ten knots and represented the coarse guidance adjustment. Peering at one terminal, Runyan saw that the turbines were engaged to combat a small drift due to ocean current. Another operator was checking the program that predicted the precise path of the hole as it rocketed up a reinforced shaft into the dome so the device there could anticipate how to move. Yet another tested the operation of the gravity detectors that would enable the lasers to focus their blast in the precise fashion to stimulate the hole to emit an even greater rocketing burst of energy. That release would reduce the mass of the hole and boost it, however minutely, further out of the earth, closer to the sanctuary of space.
Everything looked in order, but Runyan felt a sickening knot in his stomach anyway. He and hundreds of others had worked very hard to determine the orbit of the hole. This site in the mid-Pacific had been selected with careful attention to the sub-mantle rock distribution to minimize any final perturbations to the hole's orbit. He was too close to this aspect of the project, though, and knew that despite all their care, this was the weak link. A small last second nudge, a drift in the orbit, one that was a bit too large for the huge turbines and the snake-fast device overhead to accommodate, and the whole gigantic enterprise could backfire, sending the hole deeper into the earth, beyond reach. Everything had seemed to function perfectly in half a dozen dry runs in which they had ambushed the hole, but allowed it to pass through their floating trap unmolested. This time they would pull the trigger. Their aim had to be true.
Runyan watched quietly for several minutes and then announced, 'It's 5 o'clock. Our ride leaves in ten minutes. Let's button it up.'
The operators glanced at him and then finished their tasks, logging out, turning their functions over to the computer and the remote monitors. One by one they sighed, pushed back from their terminals and left the room. The last one leaned over and gave his terminal a perfunctory kiss and a pat. Runyan smiled, clapped him on the shoulder in sympathy, and followed him out.
They gathered by the pad and the helicopter dropped down out of the dark sky right on schedule. Runyan knew each of the men intimately, but went through the formality of checking each off on a list as they bearded the helicopter, attesting that they were safely off the platform. Then he climbed aboard himself and didn't look back.
Back on the Bradford , Runyan stopped in the galley to choke down a doughnut and sip another cup of coffee. Then he lamed the gathering crowd on the deck, their backs to the rosy dawn, their eyes on that which they couldn't see, a hundred miles away across the flat ocean expanse. Runyan sought out Korolev. The Russian turned to face him, and they shook hands mutely, sombrely, and then leaned on the rail staring like all the others.
After a while Korolev grumbled.
'I saw a report the other day.'
Runyan listened in silence.
'Seismic activity along the trajectory,' the Russian continued.
'Just statistical. Not a strong signal. But real, I think.'
He took a sheet of note paper from his pocket and slowly and methodically tore it into strips, and the strips into bits.
When he finished, he spoke again.
'A definite increase in earthquake activity. No big quakes, but a larger number of small tremors. A weakening of the earth. The first small signs.'
Runyan nodded.
'Nervous?' he asked, gesturing at the scraps in the Russian's gnarled fist.
'Yes,' Korolev smiled, 'but no, this is something else. A little trick your Mr Fermi taught us years ago. The Manhattan Project. If we see nothing, we have a dud. If it works,' he lifted his fistful of confetti, 'we have a little hint of how well.'
At a pre-arranged time they put on dark goggles. All was silent on the Bradford. Runyan thought briefly of his wife. Then a new star was born.
After the initial flash, Runyan whipped off his goggles. The fireball grew rapidly, expanding along the horizon, blasting upward. Outward it rushed, silently, painfully white, looming, violent, menacing. No, Runyan heard himself telling it, no, that's big enough. He had to crane his neck to see the top. No. No. It was impossibly big, and still, it spread, implacable, ravishing the sky. They were safe at a hundred miles, Runyan thought, they had to be. But in a detached way he could feel a primal force gathering in his belly, forcing a scream towards his throat.
Then it paused, sated, halted its outward rush, and began to billow even taller.
They watched quietly, all diminished by the horrifying splendour. After long minutes, Runyan could make out the shock ripping towards them at unbelievable speed across the surface of the water.
'Hold on,' he heard Korolev mutter.
The Russian grabbed the railing with his free hand. His lips moved as he counted to himself, watching the shock front and tracing its path. Then he threw the shards of paper in the air between himself and Runyan. The shock arrived with the roar of an express tram, and the bits of confetti leapt sideways. Korolev watched them continue their wafting fall to the deck.
'It was a big one, Alex,' the Russian growled over the continuous rumble, 'a very big one. Pray the recoil was in the right direction.'
