“The thing that's hard about it—the thing that makes it so hard when the person you love has been taken from you, not by something evil you could have seen coming but by random, pure chance—is that you find yourself suddenly living through a history other than the one you expected to live, through no fault of your own. I feel . . . it's hard to describe, but I feel weirdly outside of time. Ever since the accident I've had these moments when I felt like a visiting guest in this world, not a permanent resident. Like sometimes I look in a mirror and I feel like I can almost see through the version of me on the other side of the glass. And sometimes I feel like I can see the history I used to be in more clearly than the history I'm in now—the real history is one where Philip and Sean and I are all together, being a family and doing whatever family things people do, and this one's like . . . like a fake version of events that I've been yanked into, where everything's gone wrong.” EvilChanceLossTime TravelAccidentDexter PalmerVersion ControlVersionAlternate UniverseOutside Of Time Book:Version Control Source: Version Control
“Rebecca approached the causality violation chamber (too grand a name for such a faulty thing), placed her hand against its door, and closed her eyes, much as Philip had during its christening years ago. There was no response from the machine; no prophecy; no apology; no advice. It did not relay the news from other, brighter timelines. It did not tell her what would have transpired had she returned from yesterday's shopping trip a few hours later, or had she turned the steering wheel left instead of right two years ago, or had she not taken that first drink, or had she turned down any one of the thousands of drinks that had followed, or had she chosen not to respond to Philip's insistent and perhaps deliberately oblivious messages during the early days of their online courtship, or had her parents or her grandparents, or her great-grandparents never met. The machine's obstinate silence was all it had to offer; the message of that silence was that she had made her choices in life, and her choices had made her in return.” ChoicesTime TravelDexter PalmerVersion ControlAlternate Universe Book:Version Control Source: Version Control
“I shouldn't tell you this, but I've been having these weird dreams like every single night for three weeks now where I'm being contacted. Not by ghosts, exactly, but people from other histories, where things turned out differently than they did here. And they're all envious. And they all say: You are so lucky. You live in the best of all possible worlds. And you don't even know it.” DreamsTime TravelGhostsDexter PalmerVersion ControlParallel LivesAlternate UniverseAlternate Universes Book:Version Control Source: Version Control
“If the future changed, and the time traveler we're talking about was from that future, and was the product of events that created that future, why wouldn't the time traveler also change when those events changed?” Time TravelDexter PalmerVersion ControlAlternate Universe Book:The Dream of Perpetual Motion Source: The Dream of Perpetual Motion
“You could consider the idea of the multiverse, and think of it as something like a tree—that is, the universe we live in is one of an uncountable number of branches of possible universes, created by random chance and the decisions of sentient beings. So, for instance, when I rang you up in the morning, there was a possible future universe in which you answered the phone, and another in which you did not, and by answering the phone you put us in one universe and not the other. In that instance the time traveler doesn't just move from the future to the past and back to the future: he moves down one branch of the universe, toward the root that's back at the beginning of time, and back up another branch.” Time TravelScientific TheoryDexter PalmerMultiverseVersion ControlAlternate Universe Book:Version Control Source: Version Control
“What we are proposing,' Alicia said, 'is that the laws of physics are such that causality violation is subject to a form of version control, one that prevents a forking of history. That instead of causality violation creating an alternate universe, one version of history is outright overwritten by another. One past is replaced with another future. Which means that the memories of the past of the people in that future are replaced with memories of a different past.' Carson interrupted. 'Including the memories of any—' 'Purely hypothetical—' '—time travelers.' 'So take our time traveler from the traditional story,' Carson continued. 'He leaves his utopian future for the past. He kills the butterfly. The Magna Carta is never written. He returns to the dystopian future that his misstep created. But he doesn't see it as a dystopia: he sees it as home, the world he grew up in, the world he left to go back in time. Because he doesn't remember that first future, and has no other world to which he can compare this one. Maybe he even sees it as a utopia. Maybe everyone does. Maybe everyone in this dark place believes that they live in the best of all possible worlds.” PhysicsTime TravelScientific TheoryDexter PalmerVersion ControlAlternate Universe Book:Version Control Source: Version Control
