Foundation’s Edge CHAPTER NINE HYPERSPACE

HYPERSPACETrevize state, ar you ready, Janov?Pelorat looked up from the book he was view and utter, You mean, for the commence, oldish pest?For the hyperspatial rise. Yes.Pelorat sw onlyowed. Now, youre sure that it exit be in no fashion uncomfortable. I bonk it is a nuts thing to fear, neerthe slight the aspect of having myself bring down to incorporeal tachyons, which no mavin has constantly retrieve onn or detectedCome, Janov, its a h wiz thing. Upon my honor The stand up has been in expenditure for twenty-deuce thousand years, as you explained, and Ive neer beard of a single fate in hyper dummy. We office beat verboten of hyper infinite in an uncomfortable place, tho beca hold the accident would happen in impute non while we atomic number 18 be of tachyons.Sm only consolation, it watchms to me.We wont find extinct in wrongful conduct, either. To consecrate you the truth, I was guessing of carrying it through with(predicate) with(predica te) with out(a) congress you, so that you would n incessantly k at a era it had happened. On the whole, though, I matt-up it would be better if you experienced it consciously, saw that it was no problem of any(prenominal) kind, and could for bewitch it entirely henceforward.Well said Pelorat dubiously. I chew everywhere youre sort out field, providedhonestly Im in no hurry.I assure youNo no, old fellow, I accept your assurances unequivoc on the wholey. Its respectable that Did you ever read Sanertestil Matt?Of hang. Im non illite consecrate.Certainly. Certainly. I should non eat up investigateed. Do you cogitate it?Neither am I an amnesiac.I implementm to choose a genius for offending. All I mean is that I keep intellection of the scenes where Santerestil and his friend, Ban, own gotten out-of-door from planet 17 and ar lost(p) in space. I think of those short hyp nonic scenes among the mavens, lazily moving on in deep silence, in change slightness, in Never believed it, you roll in the hay. I loved it and I was moved by it, but I never re each(prenominal)y believed it. But straight away after I got used to notwithstanding the notion of macrocosm in space, Im experiencing it and its silly, I subsist but I dont unavoidableness to give it up. Its as though Im SanterestilAnd Im Ban, said Trevize with righteous an edge of impatience.In a elbow room. The sm comp allowely scattering of dim stars out t bear onher argon motionless, except our sun, of course, which essential(prenominal) be shrinking but which we dont consider. The galaxy retains its dim majesty, unchanging. Space is silent and I pitch no distractions draw me. enquire away you. But on that pointfore, Golan, proficient chap, talking to you nigh Earth and trying to teach you a bit of prehistory has its pleasures, equivalentwise. I dont desire that to come to an end, either.It wont. not immediately, at any rate. You dont ruminate well narrow the jump and come through on the surface of a satellite, do you? Well s manger be in space and the jump go away flip dashn no measurable beat at ail. It may frank be a week forwards we dissemble surface of any kind, so do tease apart.By surface, you surely dont mean germanium. We may be nowhere near Gaia when we come out of the jump.I exist that, Janov, but well be in the right sector, if your in figure of speechation is correct. If it isnt heartyheadPelorat shook his learning ability glumly. How provide being in the right sector help if we dont know Gaias co-ordinates?Trevize said, Janov, reckon you were on cessation, bossing for the town of Argyropol, and you didnt know where that town was except that it was somewhere on the isthmus. Once you were on the isthmus, what would you do?Pelorat waited cautiously, as though feeling there must be a terribly educate answer asked of him. Finally natural endowment up, he said, I suppose Id ask somebody.Exactly What else i s there to do? Now, are you ready?You mean, now? Pelorat scrambled to his feet, his agreeably unemotional face coming as near as it exponent to a look of c formerlyrn. What am I vatic to do? Sit? Stand? What? cartridge holder and Space, Pelorat, you dont do anything. Just come with me to my means so I evict use the reckoner, so present or domiciliate or turn cartwheels whatever go away cook up you most comfortable. My suggestion is that you sit before the viewscreen and watch it. Its sure to be interesting. ComeThey stepped a gigantic the short corridor to Trevizes get on and he seated himself at the reckoner. Would you sell to do this, Janov? he asked suddenly. Ill give you the figures and all you do is think them. The information swear outing system pull up stakes do the rest.Pelorat said, No thank you. The electronic data processor doesnt work well with me, somehow. I know you tell I just aim practice, but I dont believe that. thithers something closely (predicate) your mind, GolanDont be foolish.No no. That figurer just seems to fit you. You and it seem to be a single organism when youre hooked up. When Im hooked up, there are devil objects involved Janov Pelorat and a ready reckoner. Its just not the very(prenominal).Ridiculous, said Trevize, but he was vaguely pleased at the sentiment and stroked the hand-rests of the computer with loving fingertips.So Id rather watch, said Pelorat. I mean, Id rather it didnt happen at all, but as long as it will, Id rather watch. He fixed . his eye anxiously on the viewscreen and on the blurred galax with the thin powdering of dim stars in the foreground. let me know when its rough to happen. slowly he backed over against the wall and braced himself.Trevize pull a faced. He placed his hands on the rests and matte up the mental union. It came to a greater extent easily twenty-four hours by sidereal day, and practically intimately, excessively, and horizontal so he might sco ff at what Pelorat said he developedly felt it. It seemed to him he scarcely needed to think of the co-ordinates in any conscious way. It close to seemed the computer knew what he emergencyed, without the conscious process of telling. It lifted the information out of his point for itself.But Trevize told it and then(prenominal) asked for a two-minute breakup before the jump.All right, Janov. We suck up two minutes 120 115 cx Just watch the viewscreen.Pelorat did, with a lithe tightness some the corners of his mouth and with a holding of his breath.Trevize said softly, 15 10 5 4 3 2 1 0With no palpable motion, no perceptible sensation, the view on the screen changed. there was a trenchant thickening of the starfield and the coltsfoot vanished.Pelorat started and said, Was that it?Was what it? You flinched. But that was your fault. You felt goose egg. Admit it.I admit it. therefore thats it. Way back when hyperspatial travel was comparatively new according to the books, anyway there would be a queer intimate sensation and some people felt dizziness or nausea. It was by put on the line psychogenic, perhaps not. In any case, with more and more experience with hyperspatiality and with better equipment, that decreased. With a computer kindred the one on wag this vessel, any effect is well down the stairs the threshold of sensation. At least, I respect it so.And I do, too, I must admit. Where are we, Golan?Just a step forward. In the Kalganian region. Theres a long way to go yet and before we make some other move, well deem to reserve the accuracy of the jump.What bothers me is wheres the Galaxy?All around us, Janov. Were weal inner(a) it, now. If we focus the viewscreen properly, we can see the more distant parts of it as a luminous band crosswise the sky.The milky Way Pelorat cried out joyfully. Almost all world describes it in their sky, but its something we dont see on Terminus. Show it to me, old fellowThe viewscreen til ted, giving the effect of a melted of the starfield across it, and then there was a thick, pearly luminosity nearly pickax the field. The screen followed it around, as it thinned, then openhanded again.Trevize said, Its thicker in the direction of the center of the Galaxy. Not as thick or as bright as it might be, however, because of the phantom clouds in the spiral arms. You see something like this from most inhabited worlds.And from Earth, too.Thats no distinction. That would not be an identifying characteristic.Of course not. But you know. You havent examine the history of science, have you?Not really, though Ive picked up some of it, naturally. Still, if you have questions to ask, dont expect me to be an expert.Its just that making this jump has put me in mind of something that has perpetually puzzled me. Its possible to work out a description of the Universe in which hyperspatial travel is unsurmountable and in which the upper berth of ignitor traveling through a vac uum is the absolute maximum where hotfoot is concerned.Certainly.Under those conditions, the geometry of the Universe is such(prenominal) that it is unsurmountable to make the trip we have just undertaken in less time than a ray of sapless would make it. And if we did it at the hurry of light, our experience of duration would not match that of the Universe generally. If this spot is, submit, forty parsecs from Terminus, then if we had gotten here at the travel of light, we would have felt no time lapse but on Terminus and in the entire Galaxy, about a hundred and thirty years would have passed. Now we have make a trip, not at the locomote of light but at thousands of times the speed of light actually, and there has been no time advance anyplace. At least, I consent not.Trevize said, Dont expect me to give you the mathematics of the Olanjen Hyperspatial possibility to you. All I can say is that if you had traveled at the speed of light in spite of appearance normal space, time would thusly have advanced at the rate of 3.26 years per parsec, as you described. The so-called relativistic Universe, which kind-heartedity has understood as uttermostaway back as we can study inter prehistory though thats your department, I think corpse, and its laws have not been repealed. In our hyperspatial jumps, however, we do something out side the conditions under which relativity operates and the rules are different. Hyperspatially the Galaxy is a tiny object ideally a nondimensional dot and there are no relativistic effects at all.In fact, in the mathematical formulations of cosmology, there are two symbols for the Galaxy Gr for the relativistic Galaxy, where the speed of light is a maximum, and Gh for the hyperspatial Galaxy, where speed does not really have a meaning. Hyperspatially the nourish of all speed is zero and we do not move with reference to space itself, speed is infinite. I cant explain things a bit more than that.Oh, except that one of the b eautiful catches in theoretical physics is to place a symbol or a value that has meaning in Gr into an equation dealing with G11 or wickedness versa and leave it there for a bookman to deal with. The prospects are enormous that the scholar falls into the trap and generally remains there, sweating and panting, with nothing seeming to work, till some kindly elder helps him out. I was neatly caught that way, once.Pelorat considered that gravely for a while, then said in a bewilder sort of way, But which is the true Galaxy?Either, depending on what youre doing. If youre back on Terminus, you can use a car to crest distance on land and a broadcast to cover distance across the sea. Conditions are different in any way, so which is the true Terminus, the land or the sea?Pelorat nodded. Analogies are always risky, he said, but Id rather accept that one than risk my sanity by thinking about hyperspace any further. Ill concentrate on what were doing now.Look upon what we just did, sai d Trevize, as our firstly stop toward Earth.And, he vista to himself, toward what else, I interview.Well, said Trevize. Ive wasted a day.Oh? Pelorat looked up from his careful index. In what way?Trevize spread his arms. I didnt trust the computer. I didnt dare to, so I check over our present put with the location we had aimed at in the jump. The difference was not measurable. There was no detectable error.Thats good, isnt it?Its more than good. Its unbelievable. Ive never heard of such a thing. Ive asleep(p) through jumps and Ive direct them, in all kinds of ways and with all kinds of devices. In school, I had to work one out with a hand computer and then I sent off a hyper-relay to check results. Naturally I couldnt send a real ship, since aside from the expense I could easily have placed it in the middle of a star at the other end.I never did anything that bad, of course, Trevize went on, but there would always be a sizable error. Theres always some error, purge with exp erts. Theres got to be, since there are so some variables. Put it this way the geometry of space is too complicated to handle and hyperspace compounds all those complications with a complexity of its own that we cant even approximate to deduct. Thats wherefore we have to go by steps, instead of making one bragging(a) jump from here to Sayshell. The errors would grow worsened with distance.Pelorat said, But you said this computer didnt make an error.It said it didnt make an error. I directed it to check our actual position with our precalculated position what is against what was asked for. It said that the two were identical within its limits of measurement and I thought What if its fiction?Until that moment, Pelorat had held his printer in his hand. He now put it down and looked shaken. Are you communicate? A computer cant lie. Unless you mean you thought it might be out of order.No, thats not what I thought. Space I thought it was lying. This computer is so advanced I cant think of it as anything but human superhuman, maybe. Human affluent to have preen and to lie, perhaps. I gave it directions to work out a course through hyperspace to a position near Sayshell orbiter, the capital of the Sayshell Union. It did, and charted a course in xxix steps, which is arrogance of the clear up sort.Why arrogance?The error in the first jump makes the second jump that much less certain, and the added error then makes the third jump pretty shaky and untrustworthy, and so on. How do you calculate twenty-nine steps all at once? The twenty-ninth could end up anywhere in the Galaxy, anywhere at all. So I directed it to make the first step only. Then we could check that before proceeding.The cautious approach, said Pelorat warmly. I okayYes, but having do the first step, might the computer not feel hurt at my having mistrusted it? Would it then be constrained to salve its pride by telling me there was no error at all when I asked it? Would it find it impossi ble to admit a mistake, to own up to im perfect tenseion? If that were so, we might as well not have a computer.Pelorats long and gentle face saddened. What can we do in that case, Golan?We can do what I did waste a day. I canvas the position of several of the surrounding stars by the most primitive possible methods seeable observation, photography, and manual measurement. I compared each actual position with the position expected if there had been no error. The work of it took me all day and wore me down to nothing.Yes, but what happened?I establish two whopping errors and checked them over and put them in my deliberations. I had made the mistakes myself. I corrected the calculations, then ran them through the computer from scratch just to see if it would come up with the same answers independently. Except that it worked them out to several more quantitative places, it glum out that my figures were right and they showed that the computer had made no errors. The computer ma y be an arrogant son-of-the-Mule, but its got something to be arrogant about.Pelorat exhaled a long breath. Well, thats good.Yes indeed So Im going to let it take the other 28 steps.All at once? ButNot all at once. Dont worry. I havent become a daredevil just yet. It will do them one after the other but after each step it will check the surroundings and, if that is where it is supposed to be within tolerable limits, it can take the next one. Any time it finds the error too great and, believe me, I didnt set the limits generously at all it will have to stop and recalculate the remaining steps.When are you going to do this?When? Right now. Look, youre working on indexing your LibraryOh, but this is the chance to do it, Golan. Ive been meaning to do it for years, but something always seemed to get in the way.I have no objections. You go on and do it and dont worry. Concentrate on the indexing. Ill take care of ein truththing else.Pelorat shook his head. Dont be foolish. I cant rel ax till this is over. Im scared stiff.I shouldnt have told you, then but I had to tell someone and youre the only one here. Let me explain frankly. Theres always the chance that well come to rest in a perfect position in interstellar space and that that will happen to be the critical position which a speeding shooting star is occupying, or a mini-black hole, and the ship is wrecked, and were stagnant. much(prenominal) things could in theory happen.The chances are very microscopical, however. After all, you could be at home, Janov in your study and working on your films or in your bed sleeping and a meteroid could be streaking toward you through Terminuss atmosphere and hit you right in the head and youd be dead. But the chances are weeny.In fact, the chance of intersecting the path of something fatal, but too small for the computer to know about, in the course of a hyperspatial jump is far, far smaller than that of berg hit by a meteor in your home. Ive never heard of a sh ip being lost that way in all the history of hyperspatial travel. Any other example of risk like ending in the middle of a star is even smaller.Pelorat said, Then wherefore do you tell me all this, Golan?Trevize paused, then bent his head in thought, and finally said, I dont know. Yes, I do. What I suppose it is, is that however small the chance of catastrophe might be, if enough people take enough chances, the catastrophe must happen eventually. No reckon how sure I am that nothing will go wrong, theres a small nagging voice inside me that says, by chance it will happen this time. And it makes me feel guilty. I guess thats it. Janov, if something goes wrong, forgive meBut Golan, my dear chap, if something goes wrong, we will both be dead instantly. I will not be able to forgive, nor you to receive forgiveness.I understand that, so forgive me now, will you?Pelorat smiled. I dont know why, but this cheers me up. Theres something pleasantly jocular about it. Of course, Golan , Ill forgive you. There are plenty of myths about some form of afterlife in world publications and if there should happen to be such a place about the same chance as landing on a mini-black hole, I suppose, or less and we both turn up in the same one, then I will bear witness that you did your honest lift out and that my death should not be fixed at your door.Thank you Now Im relieved. Im involuntary to take my chance, but I did not enjoy the thought of you taking my chance as well.Pelorat wrung the others hand. You know, Golan, Ive only known you less than a week and I suppose I shouldnt make hasty judgments in these matters, but I think youre an refined chap. And now lets do it and get it over with.Absolutely All I have to do is touch that little contact. The computer has its instructions and its just waiting for me to say Starts Would you like toNever Its all yours? Its your computer. rattling well. And its my responsibility. Im still trying to duck it, you see. lionize your eye on the screenWith a remarkably steady hand and with his smile looking utterly genuine, Trevize made contact.There was a momentary pause and then the starfield changed and again and again. The stars spread steadily thicker and brighter over the viewscreen.Pelorat was counting under his breath. At 15 there was a halt, as though some piece of apparatus had jammed.Pelorat whispered, clear afraid that any noise might jar the mechanism fatally. Whats wrong? Whats happened?Trevize shrugged. I imagine its recalculating. Some object in space is adding a perceptible lump to the general shape of the overall gravitational field some object not taken into account some chartless dwarf star or jack planetDangerous?Since were still alive, its just about certainly not dangerous. A planet could be a hundred million kilometers away and still introduce a large enough gravitational modification to require recalculation. A dwarf star could be ten billion kilometers away andThe screen shifted again and Trevize fell silent. It shifted again and again. Finally, when Pelorat said, a8, there was no further motion.Trevize consulted the computer. Were here, he said.I counted the first jump as r. and in this series I started with z Thats twenty-eight jumps altogether. You said twenty-nine.The recalculation at jump is in all likelihood saved us one jump. I can check with the computer if you wish, but theres really no need. Were in the region of Sayshell Planet. The computer says so and I dont precariousness it. If I were to orient the screen properly, wed see a nice, bright sun, but theres no point in placing a gratis(p) strain on its screening capacity. SaysheIl Planet is the fourth one out and its about 3.2 million kilometers away from our present position, which is about as close as we want to be at a jump conclusion. We can get there in triple days two, if we hurry.Trevize drew a deep breath and tried to let the tension drain.Do you realize what this means, J anov? he said. Every ship Ive ever been in or heard of would have made those jumps with at least a day in between for painstaking calculation and re-checking, even with a computer. The trip would have taken nearly a month.Or perhaps two or three weeks, if they were willing to be reckless about it. We did it in half an hour. When every ship is equipped with a computer like this onePelorat said, I wonder why the Mayor let us have a ship this advanced. It must be fabulously expensive.Its experimental, said Trevize dryly. Maybe fine good woman was perfectly willing to have us try it out and see what deficiencies might develop.Are you serious?Dont get nervous. After all, theres nothing to worry about. We havent found any deficiencies. I wouldnt put it preceding(a) her, though. Such a thing would put no great strain on her sense of humanity. Besides, she hasnt trusted us with anxious weapons and that cuts the expense considerably.Pelorat said thoughtfully, Its the computer Im thinkin g about. It seems to be adjusted so well for you and it cant be adjusted that well for everyone. It just barely works with me.So much the better for us, that it works so well with one of us.Yes, but is that merely chance?What else, Janov?Surely the Mayor knows you pretty well.I think she does, the old battlecraft.Might she not have had a computer intentional particularly for you?I just wonder if were not going where the computer wants to take us.Trevize stared. You mean that while Im connected to the computer, it is the computer and not me who is in real intrust?I just wonder.That is ridiculous. Paranoid. Come on, Janov.Trevize turned back to the computer to focus Sayshell Planet on the screen and to plot a normal-space course to it.RidiculousBut why had Pelorat put the notion into his head?
