“No,” said Rissa, eyes growing wide. Her voice was shaking with excitement. “No—it’s from you.”

“But… but that’s crazy,” Keith said. “There’s no way I’m going to be alive ten billion years from now.”

“Unless it’s a relativistic effect,” said Hek, “or perhaps suspended animation.”

“Or…” said Rissa, her voice still shaking.

Keith looked at her. “Yes?”

She started jogging out of the bay.

“Where are you going?” barked Hek.

“To find Boxcar,” she shouted. “I want to tell her that our life-prolongation experiments are going to succeed beyond our wildest dreams.”

ZETA DRACONIS

Glass rose from the clover-covered ground. “Perhaps you need some time to rest,” he said. “I’ll be back in a little while.”

“Wait,” said Keith. “I want to know who you are. Who you really are.”

Glass said nothing, his head inclined to one side.

Keith got to his feet as well. “I’ve got a right to know. I’ve answered every one of your questions. Now, please, answer this one of mine.”

“Very well, Keith.” Glass spread his arms. “I’m you—Gilbert Keith Lansing—but you of the future. You don’t know how long I’d been racking my brain trying to remember what the bloody G stood for.”

Keith’s jaw had dropped. “That—that can’t be right. You can’t be me.”

“Oh, yes I am,” said Glass. “Of course, I’m a little bit older.” He touched the side of his smooth, transparent head, then made the wind-chime laughter sound. “See? I’ve lost all my hair.”

Keith narrowed his eyes. “How far in the future are you from?”

“Well,” said Glass, gently, “actually, you’ve got it backward. We are in my present. The appropriate question is, how far from the past are you from?”

Keith felt himself losing his balance. “You mean—you mean this isn’t 2094?”

“Twenty-ninety-four what?”

“The Earth year 2094—2094 n.o. Two thousand and ninety-four years after the birth of Christ.”

“Who? Oh, wait—my reckoner just reminded me. Let me work it out; I know the current year in absolute counting from the creation of the universe, but… ah, okay. In your system, this is the year ten billion, six hundred and forty-six million, three hundred and ninety-seven thousand, two hundred and eighty-one.”

Keith staggered back a half pace. “You sent back our time capsule.”

“That’s right.”

“How—how did I get here?”

“When your pod passed through the shortcut, I locked you into stasis. Time passed in the universe, but not for you. When it got to be this year, I unlocked you. Don’t worry, though. I intend to put you back where you came from.” A pause. “Remember that pink nebula you saw as you came out of the gate? That’s what’s left of what used to be Sol.”

Keith’s eyes went wide.

“Don’t be concerned,” said Glass. “No one was injured when Sol went nova. It was all carefully engineered. See, that type of star doesn’t naturally go nova; it just decays to a white dwarf. But we like to recycle. We blew it up so that its metals would enrich the interstellar medium.”

Keith felt dizzy. “And how—how are you going to return me to my time?”

“Through the shortcut, of course. Time travel to the past works well; we just can’t do it to the future—that’s why we had to let you come forward in stasis through ten billion years. Ironically, it turns out that it’s forward time travel, not backward travel, that results in unsolvable paradoxes, making it impossible. We’ll send you back to the moment you left. You don’t have to worry about your friends missing you; no matter how many hours you generously stay with us, we’ll get you to Tau Ceti at the time you’re expected.”

“This is incredible.”

Glass shrugged. “It’s science.”

“It’s magic,” said Keith.

Glass shrugged again. “Same thing.”

“But—but—if you’re really me, if you’re really from Earth, then why did you screw up on the simulation?”

“Pardon?”

“The Earth simulation. It has errors in it. Fields full of four-leaf clover, something only ever found as the occasional mutant, and birds that I’ve never seen before.”

“Oh.” The wind-chime sound. “My mistake. I took the simulation from some ancient recordings we had, but I was probably a bit sloppy. Let me just check with my reckoner… yup, my fault. It is a perfect simulation of Earth, but of Earth about one-point-two million years after you were born. The things that were out of place were species that hadn’t yet evolved in your time. Come to think of it, you wouldn’t have recognized the constellations, either, if I’d ever let it become nighttime.”

“My God,” said Keith. “I hadn’t even begun to think about evolution. If you’re ten billion years older than me, then—then you’re older than any form of life on Earth in my time.”

Glass nodded. “By your time, life had been evolving on Earth for four billion years. But there are Earth-descended life-forms in this time that are products of fourteen billion years of evolution. You’ll never believe what daisies evolved into—or sea anemones, or the bacteria that caused whooping cough. In fact, I had lunch a few days ago with someone who evolved from whooping-cough bacteria.”

“You’re kidding.”

“No, I’m not.”

“But it’s incredible…”
