“What do you think about all this, Harry?” Norman said, dropping into a chair next to him.
“I think it’s perfectly clear,” Harry said, “that it is a waste of time.”
“This fin they’ve found underwater?”
“I don’t know what it is, but I know what it isn’t. It isn’t a spacecraft from another civilization.”
Ted, standing nearby, turned away in annoyance. Harry and Ted had evidently had this same conversation already. “How do you know?” Norman asked.
“A simple calculation,” Harry said, with a dismissing wave of his hand. “Trivial, really. You know the Drake equation?”
Norman did. It was one of the famous proposals in the literature on extraterrestrial life. But he said, “Refresh me.”
Harry sighed irritably, pulled out a sheet of paper. “It’s a probability equation.” He wrote:
p = fpnhflfifc
“What it means,” Harry Adams said, “is that the probability, p, that intelligent life will evolve in any star system is a function of the probability that the star will have planets, the number of habitable planets, the probability that simple life will evolve on a habitable planet, the probability that intelligent life will evolve from simple life, and the probability that intelligent life will attempt interstellar communication within five billion years. That’s all the equation says.”
“Uh-huh,” Norman said.
“But the point is that we have no facts,” Harry said. “We must guess at every single one of these probabilities. And it’s quite easy to guess one way, as Ted does, and conclude there are probably thousands of intelligent civilizations. It’s equally easy to guess, as I do, that there is probably only one civilization. Ours.” He pushed the paper away. “And in that case, whatever is down there is not from an alien civilization. So we’re all wasting our time here.”
“Then what is down there?” Norman said again.
“It is an absurd expression of romantic hope,” Adams said, pushing his glasses up on his nose. There was a vehemence about him that troubled Norman. Six years earlier, Harry Adams had still been a street kid whose obscure talent had carried him in a single step from a broken home in the slums of Philadelphia to the manicured green lawns of Princeton. In those days Adams had been playful, amused at his turn of fortune. Why was he so harsh now?
Adams was an extraordinarily gifted theoretician, his reputation secured in probability-density functions of quantum mechanics which were beyond Norman’s comprehension, although Adams had worked them out when he was seventeen. But Norman could certainly understand the man himself, and Harry Adams seemed tense and critical now, ill at ease in this group.
Or perhaps it had to do with his presence as part of a group. Norman had worried about how he would fit in, because Harry had been a child prodigy.
There were really only two kinds of child prodigies-mathematical and musical. Some psychologists argued there was only one kind, since music was so closely related to mathematics. While there were precocious children with other talents, such as writing, painting, and athletics, the only areas in which a child might truly perform at the level of an adult were in mathematics or music. Psychologically, such children were complex: often loners, isolated from their peers and even from their families by their gifts, for which they were both admired and resented. Socialization skills were often retarded, making group interactions uncomfortable. As a slum kid, Harry’s problems would have been, if anything, magnified. He had once told Norman that when he first learned about Fourier transforms, the other kids were learning to slam-dunk. So maybe Harry was feeling uncomfortable in the group now.
But there seemed to be something else… Harry appeared almost angry.
“You wait,” Adams said. “A week from now, this is going to be recognized as one big fat false alarm. Nothing more.”
You hope, Norman thought. And again wondered why.
“Well, I think it’s exciting,” Beth Halpern said, smiling brightly. “Even a slim chance of finding new life is exciting, as far as I am concerned.”
“That’s right,” Ted said. “After all, Harry, there are more things in heaven and earth than are dreamed of in your philosophy.”
Norman looked over at the final member of the team, Arthur Levine, the marine biologist. Levine was the only person he didn’t know. A pudgy man, Levine looked pale and uneasy, wrapped in his own thoughts. He was about to ask Levine what he thought when Captain Barnes strode in, a stack of files under his arm.
“Welcome to the middle of nowhere,” Barnes said, “and you can’t even go to the bathroom.” They all laughed nervously. “Sorry to keep you waiting,” he said. “But we don’t have a lot of time, so let’s get right down to it. If you’ll kill the lights, we can begin.”
The first slide showed a large ship with an elaborate superstructure on the stern.
“The Rose Sealady,” Barnes said. “A cable-laying vessel chartered by Transpac Communications to lay a submarine telephone line from Honolulu to Sydney, Australia. The Rose left Hawaii on May 29 of this year, and by June 16 it had gotten as far as Western Samoa in the mid-Pacific. It was laying a new fiber-optics cable, which has a carrying capacity of twenty thousand simultaneous telephonic transmissions. The cable is covered with a dense metal-and-plastics web matrix, unusually tough and resistant to breaks. The ship had already laid more than forty-six hundred nautical miles of cable across the Pacific with no mishaps of any sort. Next.”

“At ten p.m. on the night of June 17, the vessel was located here, midway between Pago Pago in American Samoa and Viti Levu in Fiji, when the ship experienced a wrenching shudder. Alarms sounded, and the crew realized the cable had snagged and torn. They immediately consulted their charts, looking for an underwater obstruction, but could see none. They hauled up the loose cable, which took several hours, since at the time of the accident they had more than a mile of cable paid out behind the ship. When they examined the cut end, they saw that it had been cleanly sheared-as one crewman said, ‘like it was cut with a huge pair of scissors.’ Next.”
A section of Fiberglas cable held toward the camera in the rough hand of a sailor.
“The nature of the break, as you can see, suggests an artificial obstruction of some sort. The Rose steamed north back over the scene of the break. Next.”
A series of ragged black-and-white lines, with a region of small spikes.
“This is the original sonar scan from the ship. If you can’t read sonar scans this’ll be hard to interpret, but you see here the thin, knife-edge obstruction. Consistent with a sunken ship or aircraft, which cut the cable.
“The charter company, Transpac Communications, notified the Navy, requesting any information we had about the obstruction. This is routine: whenever there is a cable break, the Navy is notified, on the chance that the obstruction is known to us. If it’s a sunken vessel containing explosives, the cable company wants to know about it before they start repair. But in this case the obstruction was not in Navy files. And the Navy was interested.
“We immediately dispatched our nearest search ship, the Ocean Explorer, from Melbourne. The Ocean Explorer reached the site on June 21 of this year. The reason for the Navy interest was the possibility that the obstruction might represent a sunken Chinese Wuhan-class nuclear submarine fitted with SY-2 missiles. We knew the Chinese lost such a sub in this approximate area in May 1984. The Ocean Explorer scanned the bottom, using a most sophisticated sidelooking sonar, which produced this picture of the bottom.”
In color, the image was almost three-dimensional in its clarity.
