“I’m me again,” said Jeff, up on his elbow, looking at her with his face tired and relaxed.
“We did it,” said Diane very slowly. “Everyone can talk to everything now.”
“Let the party begin,” said Jeff, opening the bottle of wine.
Thought Experiment
Ralph Drumm, Jr., as we all know, devised the first practicable method of time travel, in our timestream and in countless others. He was an engineer and a good one, or he would not have figured it out, but in one significant way, he simply had not thought things through.
It was mere happenstance that Ralph even had the time and inclination to consider the matter, that day in the dentist’s chair. It wasn’t as though he needed any dental work: Ralph had always had perfect teeth, thanks to fluoride, heredity, nutrition, and a touch of obsessive-compulsive disorder. Most of the time, all he needed from the dentist was a quick cleaning, and he was done. But this time he opted for a little something extra: whitening. Ralph had always thought his perfect teeth would surely be more perfect if they were whiter.
The whitening process took an hour and a half, and it was not as much fun as the advertising brochure promised. But Ralph had a great fondness for thought experiments, so he set his mind to figuring out how to disassociate himself from the dentist’s chair. Being an engineer, he thought it through in a very logical and orderly way.
It was Ralph’s genius to intuit that time travel is accomplished entirely in your head: you just need some basic software development skills, plus powers of concentration that work in all four dimensions. It seemed simple enough, merely a matter of disassociating not only his mind, but also his body. A trick, a mere bagatelle, involving a sort of n-dimensional mental toolbar that controls the user’s timeshadow. The body stays behind, where it started, and the timeshadow travels freely until it alights in another time and place, where it generates a copy of the original worldline, body and all, in the timestream.
Ralph wondered why nobody had ever thought of it before. He was about to test it when the hygienist came back and started hosing out the inside of his mouth. Better leave this until I get home, Ralph thought. Even if it didn’t work, it was a wonderful theory, and it certainly whiled away ninety minutes that would otherwise have been entirely wasted, intellectually.
At home, Ralph got to work. He set up a few temporal links on the toolbar in his head: first, an easy bit of pre-industrial England. He should fit in there rather nicely, he thought, and they’d speak English. After that, he planned an iconic weekend in cultural history, and a couple of exciting historical events it would be fascinating to witness. Then, focusing the considerable power of his mind, he activated the first link.
Wessex, 144 °C.E.
The weekly market looked like a rural food co-op run by the Society for Creative Anachronism. People wearing homespun clothing in dull tones of brown and green and blue walked around with baskets, buying vegetables from similarly clad peasants who sat on the ground. In one area, a tinker was mending pots; in another, a shoemaker was stitching clunky but serviceable clogs.
The smell was a little strong — body odors, horse manure, wet hay, rotting vegetation, cooking cabbage — but Ralph felt right at home. He’d devised himself a costume that he thought would look nondescript in any time period, and carried a pocketful of Roosevelt dimes, figuring silver was silver, and Roosevelt did look a little like Julius Caesar.
He looked around nervously, but no one had noticed him materialize, even though he was right in the middle of the crowd. It was as if he’d been there all along, he thought. Ralph was unaware of the most basic tenet of time travel, as we understand it now: that the traveler’s arrival in a timestream changes both the future and the past, because his timeshadow extends for the length of his life. His present is his own, but his past in this timestream belongs to another self, with whom he is now entangled.
Ralph, our Ralph, was hungry, despite the unappetizing stink. There was a woman selling pasties from a pot, and another selling soup that was boiling on a fire. Neither of the women looked very clean, and each of them was coughing a lot and spitting out phlegm on the ground. Ralph decided that the soup was probably the safer choice, until he noticed how it was served: ladled into a bowl that each customer drank from in turn. Next time, he’d remember to bring his own cup.
He noticed a man grilling meat on wooden skewers. Just the thing. There was a small crowd around the charcoal-filled trough: a couple of rough-looking men, an old woman, some younger women with truculent expressions on their faces, and a handful of children. A quartet of buskers was singing a motet in mournful medieval harmony. A girl-child of about twelve watched him solemnly and with interest as he approached. Ralph hoped he hadn’t made some dreadfully obvious mistake in his clothing, so that he looked a foreigner, but no one else seemed to be paying any attention to him.
As he waited his turn, the child’s unblinking stare made him nervous. He was afraid to meet her eyes, and gazed earnestly at his feet, at the ash-dusted charcoal blocks, at the meat. He quickly made his way to the vendor and handed him a dime. The man gazed at it in disbelief, and then looked at Ralph with a canny mixture of greed and suspicion.
“Geunne me unmælice unmæta begas, hæenan hund!”
It was a salad of vowels, fricatives, and glottal stops. But Ralph had realized it would be hard to get a handle on the local dialect, and figured he could get by on charm and sympathy until he worked it out. He smiled, and gestured in sign language that he was deaf.
The vendor stepped back suddenly and, with an expression of fear and revulsion pointed at Ralph and shouted “Swencan bealohydig hwittuxig hæenan, ellenrofe freondas! Fyllan æfunca sweordum!” The crowd turned toward him, and started in his direction. They did not look friendly. They were shouting words he could almost understand.
Ralph jabbed desperately at the next link on his mental toolbar.
Bethel, New York, 1969.
His heart pounding, Ralph found himself in a farmer’s field, in a sea of mud and rain and under-clothed young people. It’s okay here, he thought. The vibe was totally mellow, and so were all the people, who were slapping mud on one another and slipsliding around playfully.
The rain was soft and warm, and when it let up, someone handed him a joint. He took a toke and passed it on. How did he know, he wondered, to do that? And why was it called a toke? Time travel was really an amazing groove….
A beautiful longhaired boy gave him a brownie, and a beautiful longhaired girl gave him a drink of something sweet and cherry-flavored from a leather wineskin. “You have such a cosmic smile,” she said. “Have a great trip, man.” She kissed him, evading his hands gracefully and moving away, her thin white caftan clinging damply to her slim body.
Then the music started, and Ralph was pulled like taffy into the story of the song. He was the minstrel from Gaul, the soldier from Dien Bien Phu, the man from Sinai mountain. What did it all mean, he wondered briefly, but then he left meaning behind, and fell into the deep, sugar-rough voice of the singer. He was music itself, pouring out over the crowd, bringing together four hundred thousand people, all separate and all one, like the leaves of a huge tree stirred by a kind breeze, moving gently in the humid, muddy, blissful afternoon.
Time passed. Someone put a ceramic peace symbol on a rawhide thong around his neck. His clothes were muddy and he took them off. Set after set of music played. The sun went down, and it got dark.
The smell was rather strong here, too, he thought: body odors again, and the stink of the overflowing latrines. It was too humid, really, and something had bitten him on the butt. He put his clothes back on, rather grumpily. Ralph was starting to come down, and he was feeling just a little paranoid. Maybe Woodstock wasn’t such a good idea….
