Death's End

Half a century of cruising in formation with the droplets made everyone familiar with their appearance, and what they saw now shocked them. The droplet on the display was still shaped like a teardrop, but its surface was no longer a perfectly smooth mirror. Instead, it was dim and coppery yellow, as though full of rust. It was as if a magician’s spell of eternal youth had failed, and the marks left by three centuries of spaceflight had all appeared at once. Instead of a shining spirit, the droplet had turned into an ancient artillery shell drifting through space. Communications with the Earth during the last few years had given these officers some basic insight into the principles of strong-interaction materials. They knew that the surface of a droplet was held in a force field generated by mechanisms inside. This force field counteracted the electromagnetic force between particles, allowing the strong nuclear force to spill out. Without the force field, strong-interaction material reverted to ordinary metal.

The droplets had died.

Next, they reviewed the post-attack data. The simulation showed that after the droplet brushed by Gravity, the mysterious perpendicular force making small heading changes vanished, and the droplet coasted along its final vector. But this only lasted a few seconds. Thereafter, the droplet began to decelerate. The combat analysis computer concluded that the force decelerating the droplet was equal in magnitude to the force that had changed its heading. The obvious conclusion was that the source of the force had shifted from pushing at the side of the droplet to pushing from the front.

Since the recording was made by high-magnification telescopic lens, it was possible to see the back of the departing droplet. The droplet turned ninety degrees so that it was perpendicular to its own direction of motion and continued to coast. Then it began to decelerate. The next scene seemed to be taken from a fairy tale—good thing Dr. West was also present, or else he would again declare the others to be suffering from hallucinations. A triangular object, about twice as long as the droplet, appeared in front of it. The staff immediately recognized it as a shuttle from Blue Space! In order to increase its propulsive power, multiple small fusion drives were attached to the hull of the shuttle. Although the nozzles of the drives all pointed away from the camera, it was still possible to see the glow they made as they operated under maximum output. The shuttle was pushing against the droplet to slow it down. And it was easy to deduce that it was also the source of the force that caused the droplets to deviate from their attack vectors.

After the shuttle’s appearance, two human figures wearing space suits appeared on the other side of the droplet—the side closest to the camera. The deceleration caused the figures to stick to the surface of the droplet; one of them held some kind of instrument in his hands and appeared to be analyzing the droplet. In the past, droplets had seemed almost divine in the eyes of humankind, not belonging to this world and not approachable. The only people who had ever come close to touching a droplet had been vaporized in the Doomsday Battle. But now, the droplet had lost all its mystery. Without its mirrorlike sheen, it seemed ordinary, broken-down, older and less advanced than the shuttle and the astronauts—some antique or piece of trash collected by the latter. A few seconds later, the shuttle and the astronauts disappeared, and the dead droplet was once again alone in space. But it continued to decelerate, indicating that the shuttle was still there pushing against it, only now invisible.

“They know how to disable the droplets!” someone cried out.

Captain Morovich could think of only one thing. Like Hunter a few minutes ago, he didn’t hesitate to push the button on his watch. The error message appeared in a red information window that appeared midair:

Failure: The self-destruct module has been dismantled.

The captain dashed out of the combat center and headed for the stern. The other officers followed.

The first person from Gravity to arrive at the gravitational wave transmission control room was Old Hunter. Though he had no authorization to enter the cabin, he wanted to try to break the link between the controller and the antenna. This would at least temporarily disable the transmission system until he figured out how to destroy the controller itself.

But someone was already there, examining the control cabin.

Hunter took out his sidearm and aimed it at the man. He wore the uniform of a sublieutenant on Gravity, not the uniform dating from the Doomsday Battle that Hunter expected to see—the man had stolen it. Hunter recognized him from the back. “I knew Commander Devon was right.”
