Larry Niven: Inconstant Moon

“You got another date?”

That was a mistake. I got no answer at all.

I could almost see her viewpoint. The extra trip for the extra bags was no big thing to fight about; but why did it have to be? How long was our love affair going to last, anyway? An hour, with luck. Why back down on a perfectly good argument, to preserve so ephemeral a thing?

“I wasn’t going to bring this up,” I shouted, hoping she could hear me through the door. The wind must be three times as loud on the other side. “We may need food for a week! And a place to hide!”

Silence. I began to wonder if I could kick the door down. Would I be better off waiting in the hall? Eventually she’d have to—

The door opened. Leslie was pale. “That was cruel,” she said quietly.

“I can’t promise anything. I wanted to wait, but you forced it. I’ve been wondering if the sun really has exploded.”

“That’s cruel. I was just getting used to the idea.” She turned her face to the door jamb. Tired, she was tired. I’d kept her up too late…

“Listen to me. It was all wrong,” I said. “There should have been an aurora borealis to light up the night sky from pole to pole. A shock wave of particles exploding out of the sun, traveling at an inch short of the speed of light, would rip into the atmosphere like—why, we’d have seen blue fire over every building!

“Then, the storm came too slow,” I screamed, to be heard above the thunder. “A nova would rip away the sky over half the planet. The shock wave would move around the night side with a sound to break all the glass in the world, all at once! And crack concrete and marble—and, Leslie love, it just hasn’t happened. So I started wondering.”

She said it in a mumble. “Then what is it?”

“A flare. The worst—”

She shouted it at me like an accusation. “A flare! A solar flare! You think the sun could light up like that—”

“Easy, now—”

“—could turn the moon and planets into so many torches, then fade out as if nothing had happened! Oh, you idiot—”

“May I come in?”

She looked surprised. She stepped aside, and I bent and picked up the bags and walked in.

The glass doors rattled as if giants were trying to beat their way in. Rain had squeezed through cracks to make dark puddles on the rug.

I set the bags on the kitchen counter. I found bread in the refrigerator, dropped two slices in the toaster. While they were toasting I opened the foie gras.

“My telescope’s gone,” she said. Sure enough, it was. The tripod was all by itself on the balcony, on its side.

I untwisted the wire on a champagne bottle. The toast popped up, and Leslie found a knife and spread both slices with foie gras. I held the bottle near her ear, figuring to trip conditioned reflexes.

She did smile fleetinglyas the cork popped. She said, “We should set up our picnic grounds here. Behind the counter. Sooner or later the wind is going to break those doors and shower glass all over everything.”

That was a good thought. I slid around the partition, swept all the pillows off the floor and the couch and came back with them. We set up a nest for ourselves.

It was kind of cozy. The kitchen counter was three and a half feet high, just over our heads, and the kitchen alcove itself was just wide enough to swing our elbows comfortably. Now the floor was all pillows. Leslie poured the champagne into brandy snifters, all the way to the lip.

I searched for a toast, but there were just too many possibilities, all depressing. We drank without toasting. And then carefully set the snifters down and slid forward into each other’s arms. We could sit that way, face to face, leaning sideways against each other.

“We’re going to die,” she said.

“Maybe not.”

“Get used to the idea, I have,” she said. “Look at you, you’re all nervous now. Afraid of dying. Hasn’t it been a lovely night?”

“Unique. I wish I’d known in time to take you to dinner.”

Thunder came in a string of six explosions. Like bombs in an air raid. “Me too,” she said when we could hear again.

“I wish I’d known this afternoon.”

“Pecan pralines!”

“Farmer’s Market. Double-roasted peanuts. Who would you have murdered, if you’d had the time?”

“There was a girl in my sorority—”

—and she was guilty of sibling rivalry, so Leslie claimed. I named an editor who kept changing his mind. Leslie named one of my old girl friends, I named her only old boy friend that I knew about, and it got to be kind of fun before we ran out. My brother Mike had forgotten my birthday once. The fiend.

The lights flickered, then came on again.

Too casually, Leslie asked, “Do you really think the sun might go back to normal?”

“It better be back to normal. Otherwise we’re dead anyway. I wish we could see Jupiter.”

“Dammit, answer me! Do you think it was a flare?”

“Yes.”

“Why?”

“Yellow dwarf stars don’t go nova.”

“What if ours did?”

“The astronomers know a lot about novas,” I said. “More than you’d guess. They can see them coming months ahead. Sol is a gee-naught yellow dwarf. They don’t go nova at all. They have to wander off the main sequence first, and that takes millions of years.”

She pounded a fist softly on my back. We were cheek to cheek; I couldn’t see her face. “I don’t want to believe it. I don’t dare. Stan, nothing like this has ever happened before. How can you know?”

“Something did.”

“What? I don’t believe it. We’d remember.”

“Do you remember the first moon landing? Aldrin and Armstrong?”

“Of course. We watched it at Earl’s Lunar Landing Party.”

“They landed on the biggest, flattest place they could find on the moon. They sent back several hours of jumpy home movies, took a lot of very clear pictures, left corrugated footprints all over the place. And they came home with a bunch of rocks.

“Remember? People said it was a long way to go for rocks. But the first thing anyone noticed about those rocks was that they were half melted.

“Sometime in the past, oh, say the past hundred thousand years; there’s no way of marking it closer than that—the sun flared up. It didn’t stay hot enough long enough to leave any marks on the Earth. But the moon doesn’t have an atmosphere to protect it. All the rocks melted on one side.”

The air was warm and damp. I took off my coat, which was heavy with rainwater. I fished the cigarettes and matches out, lit a cigarette and exhaled past Leslie’s ear.

“We’d remember. It couldn’t have been this bad.”

“I’m not so sure. Suppose it happened over the Pacific? It wouldn’t do that much damage. Or over the American continents. It would have sterilized some plants and animals and burned down a lot of forests, and who’d know? The sun is a four percent variable star. Maybe it gets a touch more variable than that, every so often.”

Something shattered in the bedroom. A window? A wet wind touched us, and the shriek of the storm was louder.

“Then we could live through this,” Leslie said hesitantly.

“I believe you’ve put your finger on the crux of the matter. Skol!” I found my champagne and drank deep. It was past three in the morning, with a hurricane beating at our doors.

“Then shouldn’t we be doing something about it?”

“We are.”

“Something like trying to get up into the hills! Stan, there’re going to be floods!”

“You bet your ass there are, but they won’t rise this high. Fourteen stories. Listen, I’ve thought this through. We’re in a building that was designed to be earthquake proof. You told me so yourself. It’d take more than a hurricane to knock it over.
