“What are you going to say?”
“That’s why I’m callin’ you, Mr. Hamasaki. We want you to help us work out what the reply should be. Any chance I could entice you down here with a free trip to Vegas? We’ll put you up at—”
“At the Hilton. Isn’t that the one with Star Trek: The Experience?”
The mayor laughed. “If that’s what you’d like. How soon could you get down here?”
Mayor Rivers was certainly savvy. Over one hundred thousand extra tourists came to Las Vegas to be part of the great signaling event; it was the best early-December business the city had ever had.
Darren Hamasaki’s first inclination had been to send a simple message in response. The aliens—whoever they might be—had signaled one flash, four flashes, nine flashes, and sixteen flashes, over and over again; those were the squares of one, two, three, and four. Darren thought the logical reply might be the cubes of the first four integers: one, eight, twenty-seven, and sixty-four. Not only would it make clear that the people of Earth understood the original message—which simply parroting it back wouldn’t necessarily have conveyed—but it would also indicate that they were ready for something more complex.
But Las Vegas was a city of spectacles; being that prosaic wouldn’t do. Darren spent a week devising a more content-rich message, using the form Frank Drake had worked out for Earth’s first attempt at communicating with aliens, back in 1974: an image made of a string of on/off bits, the length of the string being the product of two prime numbers—in this case 59 and 29.
Arranging the bits as a grid of 59 rows each 29 columns wide produced a crude picture. Darren coded in a simple diagram of a human being, and, because ever since he’d read Lilly in college, he’d believed dolphins were intelligent, a simple diagram of a bottle-nosed dolphin, too. He then put binary numbers underneath, expressing the total populations of the two species, and a crude diagram of the western hemisphere of the Earth, showing that the humans lived on the land and the dolphins in the ocean.
Media from all over the world came to cover the event. Mayor Rivers and Darren were invited to the master control room of the Clark County Power Authority. The entire power grid could be controlled from a single computer there. And, at precisely 10:00 p.m., the mayor pushed the key to start the program running. It began—and would end—with one solid minute of darkness, then a solid minute of light, and then another of darkness, to frame the message. Then the glowing marquee at Caesars Palace winked at the night sky, the floodlights at Luxor strobed against the blackness, the neon tubes at the MGM Grand flickered off and on. All along the Las Vegas strip, and in all the surrounding streets, the lights blinked the 1,711 bits of Darren’s reply.
Out front of Bally’s, surrounded by a huge crowd, a giant grid of lights—specially powered by gas generators—filled in with the pixels of the message, one after the other, line by line, from upper left to lower right, painting it as it was transmitted. The crowd cheered when the human figure was finished, thousands of people raising their right arms in the same salute of greeting portrayed in the message.
After the message had been completed, the mayor took to the podium and addressed the assembled mass, thanking them for their orderly conduct. Then His Honor invited Darren to say a few words.
Darren felt the need to put it all in perspective. “Of course, Groombridge 1618 is almost sixteen light-years from Earth,” he said into the mike, his voice reverberating off the canyon of hotels surrounding him. “That means it will take sixteen years for our signal to reach the aliens there, and another sixteen before any reply they might send could be received.” This being Las Vegas, there were already betting pools about what date the aliens might reply on, and what the content of their next message might be.
Darren refrained from remarking about how exceedingly unlikely it would be that the aliens would be able to detect one blinking city against the glare of Earths sun behind it; if humanity ever really wanted to seriously respond, it would likely need to build a massive laser to do so.
“Still,” said Darren, summing up, “we’ve had a lot of fun tonight, and we’ve certainly made history: humanity’s first response to an alien signal. Let’s hope that if a reply does come, thirty-odd years from now, we’ll have made new friends.”
The head of the power authority had the final words for the evening; the crowd was already dispersing by this point—heading back to the casinos, or the hotels, or the late Lance Burton show during which his assistants were topless, or any of the hundreds of other diversions Las Vegas offered at night.
Darren felt a twinge of sadness. Ele’d enjoyed his fifteen minutes of fame—but now, of course, the story would slip from public consciousness, and he’d go back to his quiet life in rural Ontario.
Or so he’d thought.
Palm-Up-Middle-Fingers-Splayed had spent the entire night in Fist-Held-Sideways’s quarters but had left by the time ship’s morning had rolled around. He was one of ten males aboard the Ineluctable, and she, one of ten females. As on the homeworld, though, females were loners, while males— who in ancient times had watched over the clutches of six eggs laid then abandoned by each female—lived communally. The Ineluctables habitat was shaped like a giant wheel, with ten spokes, each one leading to a different female’s lair; the males lived together in the hub.
It was shortly after the fifth daypart when the computer turned on a bright light to get Palm-Up-Middle-Fingers-Splayed’s attention. The digitized blue hands on the monitor screen signed the words with precise, unemotional movements. “A response has been received from the third planet.”
Palm-Up-Middle-Fingers-Splayed gave himself a three-point launch down the corridor, pushing off the bulkhead with both feet and his broad, flat tail. He barreled into the communications room. Waiting there were three other males, plus one female, Captain Curling-Sixth-Finger herself, who had come into the hub from her command module at the end of spoke one.
“I see we’ve made contact,” signed Palm-Up-Middle-Fingers-Splayed. “Has the reply been deciphered yet?”
“It seems pretty straightforward,” said Palm-Down-Thumb-Extended. “It’s a standard message grid, just like the ones we were planning to use for our later messages.” He made a couple of signs at the camera eye on the computer console, and a screen came to life, showing the message.
“The one on the left is the terrestrial form,” continued Palm-Down-Thumb-Extended. “The one on the right, the aquatic form. It was the terrestrial form that sent the message. See those strings beneath the character figures? We think those might be population tallies—meaning there are far, far more of the terrestrial form than of the aquatic one.”
“Interesting that a technological race is still subject to heavy predation or infant mortality,” signed Palm-Up-Middle-Fingers-Splayed. “But it looks as though only a tiny fraction survive to metamorphose into the adult aquatic form.”
“That’s my reading of it, too,” said Palm-Down-Thumb-Extended. His hands moved delicately, wistfully. There had been a time, of course, when the <hand-sign-naming-his-species> had faced the same sort of thing, when six offspring were needed in every clutch, and a countless clutches were needed in a female’s lifetime, just in hopes of getting two children to live to adulthood. So many had fallen prey to gnawbeasts and skyswoopers and bloodvines—
But now—
But now.
Now almost all offspring survived to maturity. There was no choice but to find new worlds on which to live. It was a difficult task: no world was suitable for habitation unless it already had an established biosphere; only the action of life could produce the carbon dioxide and oxygen needed to make a breathable atmosphere. And so the Ineluctable traveled from star to star, looking for worlds that were fecund but not yet overcrowded with their own native life forms.
