“You see, these fundamental constants like the ‘gosh numbers’ determine whether or not life can exist in the universe. Among very many other things, to be sure. But if some of them were a little higher or a little lower, life could not exist. Do you see the logical consequence of that statement? Yes, I think you do. It is a simple syllogism. Major premise, the ‘gosh numbers’ are not fixed by natural law but could have been different if certain different events had taken place at ‘Point X’. Minor premise, if they were different in certain directions, the universe would be less hospitable to life. Conclusion? Ah, that’s the heart of it. Conclusion: If they were different in certain other directions, the universe might be more hospitable to life.”
And he stopped talking, and sat regarding me, reaching down into a carpet slipper with one hand to scratch the sole of his foot.
I don’t know which of us would have out-waited the other then. I was trying to digest a lot of very indigestible ideas, and old Albert, he was determined to give me time to digest them. Before either of those could happen Paul Hall came trotting into the cubicle I had made my own yelling, “Company! Hey, Robin! We’ve got visitors!”
Well, my first thought was Essie, of course; we’d talked; I knew she was on her way to the Kennedy launchport at least, even if not actually waiting there for our orbit to settle down and get off. I stared at Paul and then at my watch. “There hasn’t been time,” I said, because there hadn’t.
He was grinning. “Come and see the poor bastards,” he chortled.
And that’s what they were, all right. Six of them, crammed into a Five. Launched from Gateway less than twenty-four hours after I had taken off from the Moon, carrying enough armament to wipe out a whole division of Oldest Ones, ready to save and profit. They had flown all the way out after Heechee Heaven, reversed course and flown all the way back. Somewhere en route we must have passed them without knowing it. Poor bastards! But they were pretty decent guys, volunteers, taking off on a mission that must have seemed insecure even by Gateway standards. I promised them that they would get a share of the profits- there was plenty to go around. It wasn’t their fault that we didn’t need them, especially considering how much we might have needed them if we had.
So we made them welcome. Janine proudly showed them around. Wan, grinning and waving his sleep-gun around, introduced them to the gentle Old Ones, placid in the face of this new invasion. And by the time all that settled down I realized that what I needed most was food and sleep, and I took both.
When I woke up the first news I got was that Essie was on her way, but not due for a while yet. I fidgeted around for a while, trying to remember everything Albert had said, trying to make a mental picture of the Big Bang and that critical third-second instant when everything got frozen. . . and not really succeeding. So I called Albert again and said, “More hospitable how?”
“Ah, Robin,” he said-nothing ever takes him by surprise- “that’s a question I can’t answer. We don’t even know what all the Machian features of the universe are, but maybe- Maybe,” he said, showing by the crinide at the corners of his eyes that he was only guessing to humor me, “maybe immortality? Maybe a faster synaptic speed of an organic brain, i.e., higher intelligence? Maybe only more planets that are suitable for life to evolve? Any of the above. Or all of them. The important thing is that we can theorize that such ‘more hospitable’ features could exist, and that it should be possible to deduce them from a proper theoretical basis. Henrietta went that far. Then she went a little further. Suppose the Heechee (she suggested) learned a little more astrophysics than we, decided what the right features would be-and set out to produce them! How would they go about it? Well, one way would be to shrink the universe back to the primordial state, and start over again with a new Big Bang! How could that happen? If you can create and destroy mass- easy! Juggle it around. Stop the expansion. Start it contracting again. Then somehow stay outside of the point concentration, wait for it to explode again-and then, from outside the monobloc, do whatever had to be done to change the fundamental dimensionless numbers of the universe, so that a new one was born that would be-well, call it heaven.”
My eyes were popping. “Is that possible?”
“To you or me? Now? No. Absolutely impossible. Wouldn’t have a clue where to begin.”
“Not to you or me, dummy! To the Heechee!”
“Ah, Robin,” he said mournfully, “who can say? I don’t see how, but that doesn’t mean they wouldn’t. I can’t even guess how to manipulate the universe to make it come out right. But that might not be necessary. You have to assume they would have some way of existing, essentially, forever. That’s necessary even to do it once. And if forever, why, then you could simply make random changes and see what happened, until you got the universe you wanted.”
He took time to look at his cold pipe thoughtfully for a moment, and then put it in his sweatshirt pocket unlit. “That’s as far as Henrietta got with her dissertation before they really fell in on her. Because then she said that the ‘missing mass’ might in fact prove that the Heechee had really begun to interfere with the orderly development of the universe-she said they were removing mass from the outer galaxies to make them fall back more rapidly. Perhaps, she thought, they were also adding mass at the center-if there is one. And she said that that might explain why the Heechee had run away. They started the process, she guessed, and then went off to hide somewhere, in some sort of timeless stasis, maybe like a big black hole, until it ran its course and they were ready to come out and start things over again. That’s when it really bit the fan! No wonder. Can you imagine a bunch of physics professors trying to cope with something like that? They said she should try for a degree in Heechee psychology instead of astrophysics. They said she had nothing to offer but conjecture and assumption-no way to test the theory, just a guess. And they thought it was a bad one. So they refused her dissertation, and she didn’t get her doctorate, and so she went off to Gateway to be a prospector and wound up where she is. Dead. And,” he said thoughtfully, pulling the pipe out again, “I do actually, Robin, think she was wrong, or at least sloppy. We have very little evidence that the Heechee had any possible way of affecting matters in any galaxy but our own, and she was talking about the entire universe.”
“But you’re not sure?”
“Not a bit sure, Robin.”
I yelled, “Don’t you at least have a fucking guess?”
“Sure thing, Robin,” he said gloomily, “but no more than that. Please calm yourself. See, the scale is wrong. The universe is too big, from anything we know. And the time is too short. The Heechee were here less than a million years ago, and the expansion time of the universe to date is something like twenty thousand times that long-recoil time could hardly be less. It’s mathematically bad odds that they would have picked that particular time to show up.”
“Show up?”
He coughed. “I left out a step, Robin. There’s another guess in there, and I’m afraid it’s my own. Suppose this is the universe the Heechee built. Suppose they somehow evolved in a less hospitable one, but didn’t like it, and caused it to contract to make a new one, which is the one we’re in. That doesn’t fit badly, you know. They could have come Out to look around, maybe found it just the way they wanted it. And now maybe the ones who did the exploring have gone back to get the rest of them.”
“Albert! For Christ’s sake!”
He said gently, “Robin, I wouldn’t be saying these things if I could help it. It’s only a conjecture. I don’t think you have any idea how difficult it is for me to conjecture in this way, and I wouldn’t be able to do it except for-well, here’s the thing. There is one possible way for something to survive a contraction and a new Big Bang, and that is to be in a place where time effectively stops. What kind of place is that? Why, a black hole. A big one. One big enough so that it is not losing mass by quantum tunneling, and therefore can survive indefinitely. I know where there’s a black hole like that, Robin. Mass, about fifteen thousand times the sun. Location, the center of our Galaxy.” He glanced at his watch and changed expression. “If my calculations are close, Robin,” he said, “your wife should be arriving about now.”
