Robert Sawyer: Calculating God

“We found no warning landscape on the surface of their world,” said Hollus. “And why, then, would they send a ship to Betelgeuse? Do you propose that it contained a splinter group who did not wish to transcend?”

“No one would go to Betelgeuse to live there; as you said, it’s just not suitable. And four hundred light-years is an awfully long way to travel just to get a gravitational boost. No, I’m sure the craft you detected had no crew or passengers; all of the Groombridge natives are still back on their home planet, uploaded into a virtual-reality world. What the Groombridge natives sent to Betelgeuse was an unmanned ship containing a catalyst of some sort — something to trigger the supernova explosion.”

Hollus’s eyestalks stopped moving. “Trigger? Why?”

My head was swimming; the thought was almost too much. I looked at the Forhilnor. “To sterilize all the worlds in this part of the galaxy,” I said. “To wipe them clean of life. If you were going to bury some computers and then transfer your consciousness into those computers, what would your greatest fear be? Why, that someone would come along and dig up the computers, damaging them or vandalizing them. On many of the worlds your starship visited, warning landscapes were created to scare people away from unearthing what was buried beneath. But on Groombridge, they decided to go one better. They tried to make sure that no one, not even anyone from another nearby star, could possibly come along and interfere with them. They knew Betelgeuse — the biggest star in local space — was eventually going to go supernova. And so they hurried things up by a few millennia, sending a catalyst, a bomb, a device that caused the supernova explosion to happen as soon as it arrived.” I paused. “In fact — in fact, that’s why you could still see the ship’s fusion exhaust, even though it was almost all the way to Betelgeuse. Of course, it had never turned around to brake — because it never intended to slow down. Instead, it rammed itself right into the star’s heart, setting off the supernova explosion.”

“That is — that is monstrous,” said Hollus. “It is entirely on one side.”

“Damn right it is,” I said. “Of course, the Groombridge natives might not have known for sure that any lifeforms existed elsewhere. After all, they reached intelligence in isolation — you said that the ark had been traveling for five thousand years. It might have just seemed a prudent precaution; they weren’t certain that they were wiping out any other civilizations.” I paused. “Or maybe they just didn’t give a damn. Maybe they thought they were God’s chosen people and that he had put Betelgeuse right there for them to use in just the way they did.”

“They may have indeed believed that,” said Hollus, “but you know it is not true.”

She was right. I did know it. I had seen the smoking gun. I had seen proof good enough even for me. I took a deep breath, trying to calm myself, trying to reign in all the thoughts running through my mind. Of course, it could have been something made by an advanced race; it could have been an artificial nova deflector; it could have been . . .

But at some point, the simplest theory — the theory that proposes the fewest elements — has to be adopted. At some point, you have to stop demanding of this question — this one question out of all the others — a higher degree of proof than required for any other theory. At some point — maybe very near the end of one’s life — you have to deal with this. At some point, the walls have to come tumbling down.

“You want me to say it?” I said. I found myself shrugging slightly, as though the idea were a sweater that needed to be shifted in order to fit comfortably. “Yes, that was God; that was the creator.”

I paused, letting the words float freely for a time, considering whether I wanted to try to recant them.

But I didn’t. “You said a while ago, Hollus, that you thought God was a being who had somehow survived the previous big crunch, had somehow managed to continue to exist from an earlier cycle of creation. If that’s true, he would indeed be a part of the cosmos. Or, if he wasn’t until now, maybe he has the ability to become — what’s the word the theologians use? — to become incarnate. God took on physical form and interposed himself between the exploding star and our three worlds.”

And suddenly another thought occurred to me: “In fact, it wasn’t the first time he’d done that!” I said. “Remember the Vela supernova from 1320 A.D. — a supernova almost as close as Betelgeuse, a supernova whose remnant is now detectable but nobody saw when it happened, nobody recorded, not the Chinese here on Earth, not anybody else here, not anyone on your planet, not anyone on the Wreed homeworld. This entity intervened then, as well, shielding us from that supernova’s radiation. You said it yourself, the first time we talked about God: the rate of supernova formation has to be carefully balanced. Well, if you can’t actually prevent supernovas, this is the next best thing.”

Hollus’s eyestalks moved closer together. She seemed to slump a bit, as if her six legs were having trouble supporting her weight. No doubt the idea that the entity was God had occurred to her before it had to me, but she clearly had not previously thought about what that meant in relation to the Vela supernova. “God does not just cause mass extinctions,” said the Forhilnor. “He routinely prevents them, too, when it suits his purpose.”

“Incredible, isn’t it?” I said, feeling as unsteady as Hollus looked.

“Maybe we should go see,” Hollus said. “If we now know where God is, maybe we should go see him.”

The idea was staggering, huge. I felt my heart jackhammering again. “But — but what we saw actually happened near Betelgeuse over 400 years ago,” I said. “And it would take at least 400 more years for your ship to get there. Why would God hang around for a total of a thousand years?”

“A typical human or Forhilnor lifespan is about a century, which is roughly fifty million minutes,” said Hollus. “God is presumably at least as old as the universe, which has existed for 13.9 billion years so far; even if he were near the end of his span, a thousand years for him would be comparable to four minutes for one of us.”

“Still, surely he won’t waste time waiting for us.”

“Perhaps not. Or perhaps he knew his actions would be observed, attracting our attention. Perhaps he will arrange to be present there again — the only location we have ever been able to identify for him — for a rendezvous at the appropriate time. He may leave to take care of other business in the interim, then return. He seems rather mobile; presumably had he known that the Groombridge ark was going to detonate Betelgeuse, he would have simply destroyed the ark before it got there. But once the explosion began, he arrived very quickly — and he could return just as quickly, by the time we get there.”

“Ifhe wants to meet us. It’s a long shot, Hollus.”

“Doubtless so. But my crew embarked on this journey to find God; this is the closest we have come, and therefore we must pursue this lead.” Her eyestalks regarded me. “You are welcomed to join us on this voyage.”

My pulse was racing again, even faster than before. But it could not be for me. “I don’t have that much time left,” I said softly.

“The Merelcas can accelerate to very close to the speed of light in less than one year,” said Hollus. “And once at such a speed, most of the distance would be covered in what would seem to be very little time; of course we would need a second year for decelerating, but in a little over two subjective years, we could be at Betelgeuse.”
