31"Golan," said Pelorat. "Does it bother you if I watch?""Not at all, Janov," said Trevize.
"If I ask questions?""Go ahead."Pelorat said, "What are you doing?"Trevize took his eyes off the viewscreen. "I've got to measure thedistance of each star that seems to be near the Forbidden World onthe screen, so that I can determine how near they really are. Theirgravitational fields must be known and for that I need mass anddistance. Without that knowledge, one can't be sure of a clean Jump.""How do you do that?""Well, each star I see has its co-ordinates in the computer's memorybanks and these can be converted into co-ordinates on the Comporelliansystem. That can, in turn, be slightly corrected for the actual positionof the For Star in space relative to Comporellon's sun, and that givesme the distance of each. Those red dwarfs1 all look quite near theForbidden World on the screen, but some might be much closer and somemuch farther. We need their three-dimensional position, you see."Pelorat nodded, and said, "And you already have the co-ordinates ofthe Forbidden World ""Yes, but that's not enough. I need the distances of the otherstars to within a percent or so. Their gravitational intensity2 in theneighborhood of the Forbidden World is so small that a slight errormakes no perceptible difference. The sun about which the Forbidden Worldrevolves or might revolve3 possessss an enormously intensegravitational field in the neighborhood of the Forbidden World and Imust know its distance with perhaps a thousand times the accuracy ofthat of the other stars. The co-ordinatss alone won't do.""Then what do you do?""I measure the apparent separation of the Forbidden World or,rather, its star from three nearby stars which are so dim it takesconsiderable magnification to make them out at all. Presumably, thosethree are very far away. We then keep one of those three stars centered onthe screen and Jump a tenth of a parsec in a direction at right angles tothe line of vision to the Forbidden World. We can do that safely enougheven without knowing distances to comparatively far-off stars.
"The reference star which is centered would still be centered afterthe Jump. The two other dim stars, if all three are truly very distant,do not change their positions measurably. The Forbidden World, however,is close enough to change its apparent position in parallactic shift. Fromthe size of the shift, we can determine its distance. If I want to makedoubly certain, I choose three other stars and try again."Pelorat said, "How long doss all that take?""Not very long. The computer doss the heavy work. I just tell it whatto do. What really takes the time is that I have to study the resultsand make sure they look right and that my instructions aren't at faultsomehow. If I were one of those daredevils with utter faith in themselvesand the computer, it could all be done in a few minutes."Pelorat said, "It's really astonishing. Think how much the computerdoes for us.""I think of it all the time.""What would you do without it?""What would I do without a gravitic ship? What would I do withoutmy astronautic training? What would I do without twenty thousandyears of hyperspatial technology behind me? The fact is that I'mmyself here now. Suppose weeeere to imagine ourselves twentythousand additional years into the future. What
