Reinhart stopped in his tracks.

“Pretty, isn’t he?” Sherikov said ironically.

“What the hell is it?

“Icarus, we call him. Remember the Greek myth? The legend of Icarus. Icarus flew…. This Icarus is going to fly, one of these days.” Sherikov shrugged. “You can examine him, if you want. I suppose this is what you came here to see.”

Reinhart advanced slowly. “This is the weapon you’ve been working on?”

“How does he look?”

Rising up in the center of the chamber was a squat metal cylinder, a great ugly cone of dark gray. Technicians circled around it, wiring up the exposed relay banks. Reinhart caught a glimpse of endless tubes and filaments, a maze of wires and terminals and parts criss-crossing each other, layer on layer.

“What is it?” Reinhart perched on the edge of a workbench, leaning his big shoulders against the wall. “An idea of Jamison Hedge—the same man who developed our instantaneous interstellar vidcasts forty years ago. He was trying to find a method of faster than light travel when he was killed, destroyed along with most of his work. After that ftl research was abandoned. It looked as if there were no future in it.”

“Wasn’t it shown that nothing could travel faster than light?”

“The interstellar vidcasts do! No, Hedge developed a valid ftl drive. He managed to propel an object at fifty times the speed of light. But as the object gained speed, its length began to diminish and its mass increased. This was in line with familiar twentieth-century concepts of mass-energy transformation. We conjectured that as Hedge’s object gained velocity it would continue to lose length and gain mass until its length became nil and its mass infinite. Nobody can imagine such an object.”

“Go on.”

“But what actually occurred is this. Hedge’s object continued to lose length and gain mass until it reached the theoretical limit of velocity, the speed of light. At that point the object, still gaining speed, simply ceased to exist. Having no length, it ceased to occupy space. It disappeared. However, the object had not been destroyed. It continued on its way, gaining momentum each moment, moving in an arc across the galaxy, away from the Sol system. Hedge’s object entered some other realm of
