Foundation and Earth 22 страница

She walked into the room. “I might have been warned.”

Trevize said, “I'm sorry, Bliss. I didn't mean it to be quite that loud.”

Fallom had followed Bliss into the room and said, “Why was there that sound, Bliss?”

“I see she's curious, too,” said Trevize. He sat back, feeling drained. The next step was to try the finding on the real Galaxy, to focus on the coordinates of the center of the Spacer worlds and see if a G-type star was actually present. Once again, he was reluctant to take the obvious step, unable to make himself put the possible solution to the actual test.

“Yes,” said Bliss. “Why shouldn't she? She's as human as we are.”

“Her parent wouldn't have thought so,” said Trevize abstractedly. “I worry about the kid. She's bad news.”

“In what way has she proven so?” demanded Bliss.

Trevize spread his arms. “Just a feeling.”

Bliss gave him a disdainful look, and turned to Fallom. “We are trying to locate Earth, Fallom.” ,

“What's Earth?”

“Another world, but a special one. It's the world our ancestors came from. Do you know what the word ‘ancestors’ means from your reading, Fallom?”

“Does it mean ?” But the last word was not in Galactic.

Pelorat said, “That's an archaic word for ‘ancestors,’ Bliss. Our word ‘forebears’ is closer to it.”

“Very well,” said Bliss, with a sudden brilliant smile. “Earth is the world where our forebears came from, Fallom. Yours and mine and Pel's and Trevize's.”

“Yours, Bliss-and mine also.” Fallom sounded puzzled. “Both of them?”

“There's just one set of forebears,” said Bliss. “We had the same forebears, all of us.”

Trevize said, “It sounds to me as though the child knows very well that she's different from us.”

Bliss said to Trevize in a low voice, “Don't say that. She must be made to see she isn't. Not in essentials.”

“Hermaphrodism is essential, I should think.”

“I'm talking about the mind.”

“Transducer-lobes are essential, too.”

“Now, Trevize, don't be difficult. She's intelligent and human regardless of details.”

She turned to Fallom, her voice rising to its normal level. “Think quietly about this, Fallom, and see what it means to you. Your forebears and mine were the same. All the people on all the worlds-many, many worlds-all had the same forebears, and those forebears lived originally on the world named Earth. That means we're all relatives, doesn't it? Now go back to our room and think of that.”

Fallom, after bestowing a thoughtful look on Trevize, turned and ran off, hastened on by Bliss's affectionate slap on her backside.

Bliss turned to Trevize, and said, “Please, Trevize, promise me you won't make any comments in her hearing that will lead her to think she's different from us.”

Trevize said, “I promise. I have no wish to impede or subvert the educational procedure, but, you know, she is different from us.”

“In ways. As I'm different from you, and as Pel is.”

“Don't be naive, Bliss. The differences in Fallom's case are much greater.”

“A little greater. The similarities are vastly more important. She, and her people, will be part of Galaxia some day, and a very useful part, I'm sure.”

“All right. We won't argue.” He turned to the computer with clear reluctance. “And meanwhile, I'm afraid I have to check the supposed position of Earth in real space.”

“Afraid?”

“Well,” Trevize lifted his shoulders in what he hoped was a half-humorous way, “what if there's no suitable star near the place?”

“Then there isn't,” said Bliss.

“I'm wondering if there's any point in checking it out now. We won't be able to make a Jump for several days.”

“And you'll be spending them agonizing over the possibilities. Find out now. Waiting won't change matters.”

Trevize sat there with his lips compressed for a moment, then said, “You're right. Very well, then-here goes.”

He turned to the computer, placed his hands on the handmarks on the desk, and the viewscreen went dark.

Bliss said, “I'll leave you, then. I'll make you nervous if I stay.” She left, with a wave of her hand.

“The thing is,” he muttered, “that we're going to be checking the computer's Galactic map first and even if Earth's sun is in the calculated position, the map should not include it. But we'll then...”

His voice trailed off in astonishment as the viewscreen flashed with a background of stars. These were fairly numerous and dim, with an occasional brighter one sparkling here and there, well scattered over the face of the screen. But quite close to the center was a star that was brighter than all the rest.

“We've got it,” said Pelorat jubilantly. “We've got it, old chap. Look how bright it is.”

“Any star at centered co-ordinates would look bright,” said Trevize, clearly trying to fight off any initial jubilation that might prove unfounded. “The view, after all, is presented from a distance of a parsec from the centered co-ordinates. Still, that centered star certainly isn't a red dwarf, or a red giant, or a hot blue-white. Wait for information; the computer is checking its data banks.”

There was silence for a few seconds and then Trevize said, “Spectral class G-2.” Another pause, then, “Diameter, 1.4 million kilometers-mass, 1.02 times that of Terminus's sun-surface temperature, 6,000 absolute-rotation slow, just under thirty days-no unusual activity or irregularity.”

Pelorat said, “Isn't all that typical of the kind of star about which habitable planets are to be found?”

“Typical,” said Trevize, nodding in the dimness. “And, therefore, what we'd expect Earth's sun to be like. If that is where life developed, the sun of Earth would have set the original standard.”

“So there is a reasonable chance that there would be a habitable planet circling it.”

“We don't have to speculate about that,” said Trevize, who sounded puzzled indeed over the matter. “The Galactic map lists it as possessing a planet with human life-but with a question mark.”

Pelorat's enthusiasm grew. “That's exactly what we would expect, Golan. The life-bearing planet is there, but the attempt to hide the fact obscures data concerning it and leaves the makers of the map the computer uses uncertain.”

“No, that's what bothers me,” said Trevize. “That's not what we should expect. We should expect far more than that. Considering the efficiency with which data concerning Earth has been wiped out, the makers of the map should not have known that life exists in the system, let alone human life. They should not even have known Earth's sun exists. The Spacer worlds aren't on the map. Why should Earth's sun be?”

“Well, it's there, just the same. What's the use of arguing the fact? What other information about the star is given?”

“A name.” —

“Ah! What is it?”

“Alpha.”

There was a short pause, then Pelorat said eagerly, “That's it, old man. That's the final bit of evidence. Consider the meaning.”

“Does it have a meaning?” said Trevize. “It's just a name to me, and an odd one. It doesn't sound Galactic.”

“It isn't Galactic. It's in a prehistoric language of Earth, the same one that gave us Gaia as the name of Bliss's planet.”

“What does Alpha mean, then?”

“Alpha is the first letter of the alphabet of that ancient language. That is one of the most firmly attested scraps of knowledge we have about it. In ancient times, ‘alpha’ was sometimes used to mean the first of anything. To call a sun ‘Alpha,’ implies that it's the first sun. And wouldn't the first sun be the one around which a planet revolved that was the first planet to bear human ,life-Earth?”

“Are you sure of that?”

“Absolutely,” said Pelorat.

“Is there anything in early legends. you're the mythologist, after all-that gives Earth's sun some very unusual attribute?”

“No, how can there be? It has to be standard by definition, and the characteristics the computer has given us ate as standard as possible, I imagine. Aren't they?”

“Earth's sun is a single star, I suppose?”

Pelorat said, “Well, of course! As far as I know, all inhabited worlds orbit single stars.”

“So I would have thought myself,” said Trevize. “The trouble is that that star in the center of the viewscreen is not a single star, it is a binary. The brighter of the two stars making up the binary is indeed standard and it is that one for which the computer supplied us with data. Circling that star with a period of roughly eighty years, however, is another star with a mass four fifths that of the brighter one. We can't see the two as separate stars with the unaided eye, but if I were to enlarge the view, I'm sure we would.”

“Are you certain of that, Golan?” said Pelorat, taken aback.

“It's what the computer is telling me. And if we are looking at a binary star, then it's not Earth's sun. It can't be.”

71.

TREVIZE broke contact with the computer, and the lights brightened.

That was the signal, apparently, for Bliss to return, with Fallow tagging after her. “Well, then, what are the results?” she asked.

Trevize said tonelessly, “Somewhat disappointing. Where I expected to find Earth's sun, I found a binary star, instead. Earth's sun is a single star, so the one centered is not it.”

Pelorat said, “Now what, Golan?”

Trevize shrugged. “I didn't really expect to see Earth's sun centered. Even the Spacers wouldn't settle worlds in such a way as to set up an exact sphere. Aurora, the oldest of the Spacer worlds, might have sent out settlers of its own and that may have distorted the sphere, too. Then, too, Earth's sun may not have moved at precisely the average velocity of the Spacer worlds.”

Pelorat said, “So the Earth can be anywhere. Is that what you're saying?”

“No. Not quite ‘anywhere.’ All these possible sources of error can't amount to much. Earth's sun must be in the vicinity of the co-ordinates. The star we've spotted almost exactly at the co-ordinates must be a neighbor of Earth's sun. It's startling that there should be a neighbor that so closely resembles Earth's sun-except for being a binary-but that must be the case.”

“But we would see Earth's sun on the map, then, wouldn't we? I mean, near Alpha?”

“No, for I'm certain Earth's sun isn't on the map at all. It was that which shook my confidence when we first spied Alpha. Regardless of how much it might resemble Earth's sun, the mere fact that it was on the map made me suspect it was not the real thing.”

“Well, then,” said Bliss. “Why not concentrate on the same co-ordinates in real space? Then, if there is any bright star close to the center, a star that does not exist in the computer's map, and if it is very much like Alpha in its properties, but is single, might it not be Earth's sun?”

Trevize sighed. “If all that were so, I'd be willing to wager half my fortune, such as it is, that circling that star you speak of would be the planet Earth. Again, I hesitate to try.”

“Because you might fail?”

Trevize nodded. “However,” he said, “just give me a moment or two to catch my breath, and I'll force myself to do so.”

And while the three adults looked at each other, Fallow approached the computer-desk and stared curiously at the handmarks upon it. She reached out her own hand tentatively toward the markings, and Trevize blocked the motion with a swift outthrusting of his own arm and a sharp, “Mustn't touch, Fallow.”

The young Solarian seemed startled, and retreated to the comfort of Bliss's encircling arm.

Pelorat said, “We must face it, Golan. What if you find nothing in real space?”

“Then we will be forced to go back to the earlier plan,” said Trevize, “and visit each of the forty-seven Spacer worlds in turn.”

“And if that yields nothing, Golan?”

Trevize shook his head in annoyance, as though to prevent that thought from taking too deep a root. Staring down at his knees, he said abruptly, “Then I will think of something else.”

“But what if there is no world of forebears at all?”

Trevize looked up sharply at the treble voice. “Who said that?” he asked.

It was a useless question. The moment of disbelief faded, and he knew very well who the questioner was.

“I did,” said Fallow.

Trevize looked at her with a slight frown. “Did you understand the conversation?”

Fallow said, “You are looking for the world of forebears, but you haven't found it yet. Maybe there isn't no such world.”

“Any such world,” said Bliss softly.

“No, Fallow,” said Trevize seriously. “There has been a very big effort to hide it. To try so hard to hide something means there is something there to hide. Do you understand what I am saying?”

“Yes,” said Fallow. “You do not let me touch the hands on the deck. Because you do not let me do that means it would be interesting to touch them.”

“Ah, but not for you, Fallom. Bliss, you are creating a monster that will destroy us all. Don't ever let her in here unless I'm at the desk. And even then, think twice, will you?”

The small byplay, however, seemed to have shaken him out of his irresolution. He said, “Obviously, I had better get to work. If I just sit here, uncertain as to what to do, that little fright will take over the ship.”

The lights dimmed, and Bliss said in a low voice, “You promised, Trevize. Do not call her a monster or a fright in her hearing.”

“Then keep an eye on her, and teach her some manners. Tell her children should be never heard and seldom seen.”

Bliss frowned. “Your attitude toward children is simply appalling, Trevize.”

“Maybe, but this is not the time to discuss the matter.”

Then he said, in tones in which satisfaction and relief were equally represented, “There's Alpha again in real space. And to its left, and slightly upward, is almost as bright a star and one that isn't in the computer's Galactic map. That is Earth's sun. I'll wager all my fortune on it.”

72.

“WELL, Now,” said Bliss, “we won't take any part of your fortune if you lose, so why not settle the matter in a forthright manner? Let's visit the star as soon as you can make the Jump.”

Trevize shook his head. “No. This time it's not a matter of irresolution or fear. It's a matter of being careful. Three times we've visited an unknown world and three times we've come up against something unexpectedly dangerous. And three times, moreover, we've had to leave that world in a hurry. This time the matter is ultimately crucial and I will not play my cards in ignorance again; or at least in any more ignorance than I can help. So far, all we have are vague stories about radioactivity, and that is not enough. By an odd chance that no one could have anticipated, there is a planet with human life about a parsec from Earth...”

“Do we really know that Alpha has a planet with human life on it?” put in Pelorat. “You said the computer placed a question mark after that.”

“Even so,” said Trevize, “it's worth trying. Why not take a look at it? If it does indeed have human beings on it, let us find out what they know about Earth. For them, after all, Earth is not a distant thing of legend; it is a neighbor world, bright and prominent in their sky.”

Bliss said thoughtfully, “It's not a bad idea. It occurs to me that if Alpha is inhabited and if the inhabitants are not your thoroughly typical Isolates, they may be friendly, and we might be able to get some decent food for a change.”

“And meet some pleasant people,” said Trevize. “Don't forget that. Will it be all right with you, Janov?”

Pelorat said, “You make the decision, old chap. Wherever you go, I will go, too.

Fallom said suddenly, “Will we find Jemby?”

Bliss said hastily, before Trevize could answer, “We will look for it, Fallom.”

And then Trevize said, “It's settled then. On to Alpha.”

73.

“Two BIG stars,” said Fallom, pointing to the viewscreen.

“That's right,” said Trevize. “Two of them. Bliss, do keep an eye on her. I don't want her fiddling with anything.”

“She's fascinated by machinery,” said Bliss.

“Yes, I know she is,” said Trevize, “but I'm not fascinated by her fascination. Though to tell you the truth, I'm as fascinated as she is at seeing two stars that bright in the viewscreen at the same time.”

The two stars were bright enough to seem to be on the point of showing a disc-each of them. The screen had automatically increased filtration density in order to remove the hard radiation and dim the light of the bright stars so as to avoid retinal damage. As a result, few other stars were bright enough to be noticeable, and the two that were reigned in haughty near-isolation.

“The thing is,” said Trevize, “I've never been this close to a binary system before.”

“You haven't?” said Pelorat, open astonishment in his voice. “How is that possible?”

Trevize laughed. “I've been around, Janov, but I'm not the Galactic rover you think I am.”

Pelorat said, “I was never in space at all till I met you, Golan, but I always thought that anyone who did manage to get into space—”

“Would go everywhere. I know. That's natural enough. The trouble with planet-bound people is that no matter how much their mind may tell them otherwise, their imaginations just can't take in the true size of the Galaxy. We could travel all our lives and leave most of the Galaxy unpenetrated and untouched. Besides, no one ever goes to binaries.”

“Why not?” said Bliss, frowning. “We on Gaia know little astronomy compared to the traveling Isolates of the Galaxy, but I'm under the impression that binaries aren't rare.”

“They're not,” said Trevize. “There are substantially more binaries than there are single stars. However, the formation of two stars in close association upsets the ordinary processes of planetary formation. Binaries have less planetary material than single stars do. Such planets as do form about them often have relatively unstable orbits and are very rarely of a type that is reasonably habitable.

“Early explorers, I imagine, studied many binaries at close range but, after a while, for settlement purposes, they sought out only singles. And, of course, once you have a densely settled Galaxy, virtually all travel involves trade and communications and is carried on between inhabited worlds circling single stars. In periods of military activity, I suppose bases were sometimes set up on small, otherwise-uninhabited worlds circling one of the stars of a binary that happened to be strategically placed, but as hyperspatial travel came to be perfected, such bases were no longer necessary.”

Pelorat said humbly, ”. It's amazing how much I don't know.”

Trevize merely grinned. “Don't let that impress you, Janov. When I was in the Navy, we listened to an incredible number of lectures on outmoded military tactics that no one ever planned, or intended to use, and were just talked about out of inertia. I was just rattling off a bit of one of them. Consider all you know about mythology, folklore, and archaic languages that I don't know, and that only you and a very few others do know.”

Bliss said, “Yes, but those two stars make up a binary system and one of them has an inhabited planet circling it.”

“We hope it does, Bliss,” said Trevize. “Everything has its exceptions. And with an official question mark in this case, which makes it more puzzling. No, Fallom, those knobs are not toys. Bliss, either keep her in handcuffs, or take her out.”

“She won't hurt anything,” said Bliss defensively, but pulled the Solarian youngster to herself just the same. “If you're so interested in that habitable planet, why aren't we there already?”

“For one thing,” said Trevize, “I'm just human enough to want to see this sight of a binary system at close quarters. Then, too, I'm just human enough to be cautious. As I've already explained, nothing has happened since we left Gaia that would encourage me to be anything but cautious.”

Pelorat said, “Which one of those stars is Alpha, Golan?”

“We won't get lost, Janov. The computer knows exactly which one is Alpha, and, for that matter, so do we. It's the hotter and yellower of the two because it's the larger. Now the one on the right has a distinct orange tinge to its light, rather like Aurora's sun, if you recall. Do you notice?”

“Yes, now that you call it to my attention.”

“Very well. That's the smaller one. What's the second letter of that ancient language you speak of?”

Pelorat thought a moment, and said, “Beta.”

“Then let's call the orange one Beta and the yellow-white one Alpha, and it's Alpha we're heading for right now.”

Chapter 17

New Earth

74.

“FOUR PLANETS,” muttered Trevize. “All are small, plus a trailing off of asteroids. no gas giants.”

Pelorat said, “Do you find that disappointing?”

“Not really. It's expected. Binaries that circle each other at small distances can have no planets circling one of the stars. Planets can circle the center of gravity of both, but it's very unlikely that they would be habitable-too far away.

“On the other hand if the binaries are reasonably separate, there can be planets in stable orbits about each, if they are close enough to one or the other of the stars. These two stars, according to the computer's data bank, have an average separation of 3.5 billion kilometers and even at periastron, when they are closest together, are about 1.7 billion kilometers apart. A planet in an orbit of less than 200 million kilometers from either star would be stably situated, but there can be no planet with a larger orbit. That means no gas giants since they would have to be farther away from a star, but what's the difference? Gas giants aren't habitable, anyway.”

“But one of those four planets might be habitable.”

“Actually the second planet is the only real possibility. For one thing, it's the only one of them large enough to have an atmosphere.”

They approached the second planet rapidly and over a period of two days its image expanded; at first with a majestic and measured swelling. And then, when there was no sign of any ship emerging to intercept them, with increasing and almost frightening speed.,

The Far Star was moving swiftly along a temporary orbit a thousand kilometers above the cloud cover, when Trevize said grimly, “I see why the computer's memory banks put a question mark after the notation that it was inhabited. There's no clear sign of radiation; either light in the night-hemisphere, or radio anywhere.”

“Me cloud cover seems pretty thick,” said Pelorat.

“That should not blank out radio radiation.”

They watched the planet wheeling below them, a symphony in swirling white clouds, through occasional gaps of which a bluish wash indicated ocean.

Trevize said, “The cloud level is fairly heavy for an inhabited world. It might be a rather gloomy one. What bothers me most,” he added, as they plunged once more into the night-shadow, “is that no space stations have hailed us.”

“The way they did back at Comporellon, you mean?” said Pelorat.

“The way they would in any inhabited world. We would have to stop for the usual checkup on papers, freight, length of stay, and so on.”

Bliss said, “Perhaps we missed the hail for some reason.”

“Our computer would have received it at any wavelength they might have cared to use. And we've been sending out our own signals, but have roused no one and nothing as a result. Dipping under the cloud layer without communicating with station officials violates space courtesy, but I don't see that we have a choice.”

The Far Star slowed, and strengthened its antigravity accordingly, so as to maintain its height. It came out into the sunlight again, and slowed further. Trevize, in co-ordination with the computer, found a sizable break in the clouds. The ship sank and passed through it. Beneath them heaved the ocean in what must have been a fresh breeze. It lay, wrinkled, several kilometers below, them, faintly striped in lines of froth.

They flew out of the sunlit patch and under the cloud cover. The expanse of water immediately beneath them turned a slate-gray, and the temperature dropped noticeably.

Fallom, staring at the viewscreen, spoke in her own consonant-rich language for a few moments, then shifted to Galactic. Her voice trembled. “What is that which I see beneath?”

“That is an ocean,” said Bliss soothingly. “It is a very large mass of water.”

“Why does it not dry up?”

Bliss looked at Trevize, who said, “There's too much water for it to dry UP. 9t

Fallom said in a half-choked manner, “I don't want all that water. Let us go away.” And then she shrieked, thinly, as the Far Star moved through a patch of storm clouds so that the viewscreen turned milky and was streaked with the mark of raindrops.

The lights in the pilot-room dimmed and the ship's motion became slightly jerky.

Trevize looked up in surprise and cried out. “Bliss, your Fallow is old enough to transduce. She's using electric power to try to manipulate the controls. Stop her!”

Bliss put her arms about Fallom, and hugged her tightly, “It's all right, Fallom, it's all right. There's nothing to be afraid of. It's just another world, that's all. There are many like this.”

Fallom relaxed somewhat but continued to tremble.

Bliss said to Trevize, “The child has never seen an ocean, and perhaps, for all I know, never experienced fog or rain. Can't you be sympathetic?”

“Not if she tampers with the ship. She's a danger to all of us, then. Take her into your room and calm her down.”

Bliss nodded curtly.

Pelorat said, “I'll come with you, Bliss.”

“No, no, Pel,” she responded. “You stay here. I'll soothe Fallom and you soothe Trevize.” And she left.

“I don't need soothing,” growled Trevize to Pelorat. “I'm sorry if I flew off the handle, but we can't have a child playing with the controls, can we?”

“Of course we can't,” said Pelorat, “but Bliss was caught by surprise. She can control Fallom, who is really remarkably well behaved for a child taken from her home and her-her robot, and thrown, willy-nilly, into a life she doesn't understand.”

“I know. It wasn't I who wanted to take her along, remember. It was Bliss's idea.”

“Yes, but the child would have been killed, if we hadn't taken her.”

“Well, I'll apologize to Bliss later on. To the child, too.”

But he was still frowning, and Pelorat said gently, “Golan, old chap, is there anything else bothering you?”

“The ocean,” said Trevize. They had long emerged from the rain storm, but the clouds persisted.

“What's wrong with it?” asked Pelorat.

“There's too much of it, that's all.”

Pelorat looked blank, and Trevize said, with a snap, “No land. We haven't seen any land. The atmosphere is perfectly normal, oxygen and nitrogen in decent proportions, so the planet has to be engineered, and there has to be plant life to maintain the oxygen level. In the natural state, such atmospheres do not occur-except, presumably, on Earth, where it developed, who knows how. But, then, on engineered planets there are always reasonable amounts of dry land, up to one third of the whole, and never less than a fifth. So how can this planet be engineered, and lack land?”

Pelorat said, “Perhaps, since this planet is part of a binary system, it is completely atypical. Maybe it wasn't engineered, but evolved an atmosphere in ways that never prevail on planets about single stars. Perhaps life developed independently here, as it once did on Earth, but only sea life.”

“Even if we were to admit that,” said Trevize, “it would do us no Good.

There's no way life in the sea can develop a technology. Technology is always based on fire, and fire is impossible in the sea. A life-bearing planet without technology is not what we're looking for.”

“I realize that, but I'm only considering ideas. After all, as far as we know, technology only developed once—on Earth. Everywhere else, the Settlers brought it with them. You can't say technology is ‘always’ anything, if you only have one case to study.”

“Travel through the sea requires streamlining. Sea life cannot have irregular outlines and appendages such as hands.”

“Squids have tentacles.”

Trevize said, “I admit we are allowed to speculate, but if you're thinking of intelligent squid-like creatures evolving independently somewhere in the Galaxy, and developing a technology not based on fire, you're supposing something not at all likely, in my opinion.”

“In your opinion, “ said Pelorat gently.

Suddenly, Trevize laughed. “Very well, Janov. I see you're logic-chopping in order to get even with me for speaking harshly to Bliss, and you're doing a good job. I promise you that if we find no land, we will examine the sea as best we can to see if we can find your civilized squids.”
