the final quadrant of the display — “is the local spiral arm, as our projection says it will be a million years from now.”
She moved the cursor to a point of orange-yellow. “And that is Sol.” “But the color code is for a red dwarf star!”
“That’s right. And that’s why we — and you — are here in Gulf City.”
Sy was studying the images. “Red dwarfs. The whole spiral arm is full of red dwarf stars — far too high a proportion of them.” He looked at each image in turn. “This is impossible. There’s no way that stellar types could change so much, and in such a short time. You must be misinterpreting the data.”
“That’s what we thought — at first. Then we began to compare recent star catalogs with ones made in the earliest days of stellar astronomy. There’s no mistake. The main sequence stars in our spiral have been changing. Randomly, with no pattern that we can see, but what used to be spectral classes G and K are becoming class M. We can’t tell when a particular star is likely to change — that’s a guess we made about the future of Sol — but in general — “ “No way!” Sy shook his head vigorously. “Not unless all the astrophysics I learned back on Pentecost is nonsense. It takes hundreds of millions of years at least for a stable star to move from one spectral class to another.” “You know the same astrophysics as we do. And we can only think of one mechanism for change. Class G and class K stars have surface temperatures between about four and six thousand degrees. Class M are more like two to three thousand. You could get those changes in stellar type for dwarf stars, if somehow you could damp the fusion reaction inside them. Lower the internal energy production, and you would lower the overall temperature.”
Sy looked frustrated. “Maybe. But can you suggest any process that could possibly do that? I know of none.”
“Nor do we. No natural process. That keeps leading us to one unpleasant conclusion. The information we’ve received from the Kermel Objects is true — we’ve done other checks on changes in stellar types. And there’s no natural way for these changes to happen. So: some other entity, living in our spiral arm of the galaxy, prefers stars of lower temperature and luminosity.”
“You mean something or someone is inducing reduced fusion reactions through the spiral arm — intentionally.”
“I mean exactly that.” Judith Niles’ forehead filled with frown lines, and she looked a dozen years older. “It’s a frightening conclusion, but it’s the only one. I don’t think the Kermel Objects are doing this, even though they seem to know a lot about it. We have some evidence that suggests they understand the whole process, and they certainly seem able to predict the rate of change in the spiral arm. But I believe the action doesn’t originate with them. What we’re seeing is the work of another species, one more like ourselves — one that has no use for the deep space preferred by Gossameres or Kermel Objects. These other creatures want to live near a star. A red, low luminosity star.”
She cleared the display, leaned back, and closed her eyes. “A long time ago humans talked of terraforming Mars and Venus, but we never did it. Just too busy blowing ourselves up, I guess, ever to get round to it. Now maybe we’ve met someone more rational and more ambitious than we were. What we are seeing is stellarforming. If it goes on, and if we don’t understand it and find out how to stop it, in another million years this whole spiral arm will have few G-type stars. That will mean the end of human planetary colonies. Eventually, that will be the end of humans. Finis.”
Judith Niles paused. She switched off all the displays.
“We think the Kermel Objects hold the key,” she said softly. “Now do you see why we’re living out here in the middle of nowhere, and why S-space and T-state are so important? In normal space, a million years used to seem like forever. But I expect to be alive, ten thousand Earth-centuries from now.”
Sy wore an expression that Peron and Elissa would have found unfamiliar. He seemed uneasy, and lacking in confidence. “I read it wrong. I thought the reason for being here in Gulf City was safety from outside interference, and control of S-space. The whole advantage of being an ‘Immortal’ was presented to us as increased subjective life span — but now I wonder about that.”
“You are right to do so. We have life-extension methods available, ones that came out of S-space research and allow increased life span in normal space. And probably they will let the subject enjoy life more keenly, too. But you can’t solve the problem thrown at us by the Kermel Objects unless you can work on it for a long time. That means Gulf City, and it means S-space.” She stood up. “Will you work on this? And will you help me to persuade your friends to do the same?”
“I’ll try.” Sy hesitated. “But I still need to think. I’ve not had the thinking time that I wanted when I headed for the tanks.”
Judith Niles nodded. “I know. But I wanted you to do your thinking with a full knowledge of what’s going on here. You have that. I’ll head back now. This chamber is self-locking when you leave. And as soon as you’re ready to do it, let’s meet again with your friends.” Now she hesitated, and her expression matched Sy’s for uneasiness. “There’s something else to be discussed, but it’s on another subject. And I want to do it when all of you are together.” She gave him a worried smile and headed for the door. For the first time, Sy could see her as a lonely and vulnerable figure. The power and intensity of personality were still there, unmistakable, but they were muted, overlain with an awareness of a monstrous unsolved problem. He thought of the splendid confidence with which the Planetfest winners had lifted off from Pentecost. They had the shining conviction that any problem in the galaxy would fall to their combined attack. And now? Sy felt older, and a great need for time to think. Judith Niles had been carrying a killing load of responsibility for a long time. She needed help, but could he provide it? Could anyone? He wanted to try. For the first time in his life, he had met someone whose intellect walked the same paths as his own, someone in whose presence he felt totally at ease. Sy leaned back in his chair. It would be ironic if that satisfaction of mind-meeting came at the same time as a problem too big for both of them. * * *
An hour later Sy was still sitting in the same position. In spite of every effort, his mind had driven back relentlessly to a single focus: the Kermel Objects. He began to see the Universe as they must see it, from that unique vantage point of the longest perspective of evolutionary time. With the T-state available, humans had a chance to experience that other world-view. Here was a cosmos which exploded from an initial singular point of incomprehensible heat and light, in which great galaxies formed, tightened into spirals, and whirled about their central axes like giant pinwheels. They clustered together in loose galactic families, threw off supercharged jets of gas and radiation, collided and passed through each other, and spawned within themselves vast gaseous nebulae.
Suns coalesced quickly from dark clouds of dust and gas, blooming from faintest red to fiery blue-white. As he watched in his mind’s eye, they brightened, expanded, exploded, dimmed, threw off trains of planets, or spun dizzily around each other. A myriad planetary fragments cooled, cracked, and breathed off their protective sheaths of gases. They caught the spark of life within their oceans of water and air, fanned it, nurtured it, and finally hurled it aloft into surrounding space. Then there was a seething jitter of life around the stars, a Brownian dance of ceaseless human activity against the changing stellar background. The space close to the stars filled with the humming-bird beat and shimmer of intelligent organic life. The whole universe lay open before it. And now the T- state became essential. Planet-based humans, less than mayflies, flickered through their brief existence in a tiny fraction of a cosmic day. The whole of human history had run its course in a single T-week, while mankind moved out from the dervish whirl of the planets into the space surrounding Sol. Then S-space had given the nearer stars; but the whole galaxy and the open vastness of intergalactic space still beckoned. And in that space, in T-state, humans could be free to thrive forever.
Sy sat back in the chair, drunk with his new vision. He could see a bright path that led from mankind’s earliest beginnings, stretching out unbroken into the farthest future.
It was the road to forever. It was a road that he wanted to take, whatever the consequences. But first, humanity had to find a way to survive the stellarforming catastrophe.
CHAPTER TWENTY-NINE
Elissa was the last to arrive at the meeting. As she hurried into the long conference room to take her seat she glanced around the table, and was struck at once by the odd seating arrangement. Judith Niles sat alone at the
