She hadn't gone back in time. The idea was

The device,' Philip said. 'What are you going to do with it?''I know how this sounds. But you'll have to trust us. We'll take possession of it. We're going to dismantle it; when we do so, the wormhole will close, making this the final version of history we live through. Then we're going to box up the device and forget about it. Lose it somewhere; burn the records. It'll end up in a warehouse right next to the Ark of Covenant.

But the hair on her arms did not stand on end; she did not experience any strange instances of déjà vu; she did not see the ghosts of future selves shimmering before her, shouting stock picks back through time.

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?

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.

But we think that if a human were to violate conventional causality—''By time traveli

She closed her eyes, and as had been her habit over these past couple of days, she began to imagine possible past histories and what she might have done to change them into the new one in which she lived, either inadvertently, or out of a misguided attempt to play God and make the world a better place, or, worse, with malice aforethought. Any time she spent in the past would have been clipped out of history, as neatly as if it had never happened, because it hadn't happened.

He pulled out his wallet and extracted a twenty-dollar bill, fastidiously folding it in half so that the crease cut across the face of Theodore Roosevelt, with its shining spectacles and its Chesire Cat grin.

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.

Later—how much later? Hard to tell. In times of tragedy clocks will trick you—Philip stood in the kitchen doorway.

I can’t comprehend why any black man with even a lick of sense would have the slightest bit of interest in time travel. Going backward in time? A black man? You have got to be out of your mind.

But who, in these modern times, slept well?

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.

And as Sean climbs into bed and closes his eyes, Mother comes, riding astride a lion the size of a house, blowing a clarion from a horn made out of a hollowed-out elephant's tusk. Her eyes have a faint crimson glow from the lasers that are mounted behind her irises, ready to fire at will.'I touched a prince's chest today and made his heart stop,' she says. 'I'll do it again if I have to: they'll see what happens if anyone gets in my way. Good night, my son. Remember that I will always keep you safe; that I am always everywhere and always here.''Good night, Mom,' Sean says, and falls asleep.And Mother recedes, wise and beautiful and strong, a genius and a hero, a punisher of thieves and a slayer of wicked men, to watch over her son in all her different versions.

That's one of our speculations, by the way. That the prior version of history that this one overwrote was horrible. Complete geopolitical mayhem; half of New York City is underwater. The United States is headed toward civil war, or ruled by an artificial-intelligence construct, or some such other thing. Real end-of-days stuff. That the instances of ourselves who existed in that history figured out what we have: that the invention of the causality violation device was the cause. That in that prior version of history, Rebecca did not die in a car accident. That she went back to the past on a mission, as a volunteer, well aware of her sacrifice.

But life isn't neat the way a story is. And if you try to pretend it is, then you just make yourself unhappy, or screw yourself over.

She drank the glass with breakfast and poured herself another. By the time she'd gotten Sean off to school (second grade) the edges had been taken off her thoughts and the world seemed as it should be: not too real, but real enough.

This is the last moment of contentment untainted by sorrow, when the brain hesitates before delivering the message to the heart that it knows it must.

But I can tell you this: that I am deeply proud of Rebecca. That she made a split-second decision to save the life of her son, turning the wheel of her vehicle so that her side of it would be impacted by an oncoming car instead of his. She gave her life in the exercise of the greatest gift that God grants us—the ability to change the trajectory of history.

And so Rebecca consigned herself to, not ignorance, but a judicious incuriosity: she decided, for the time being, to live with the constant, cryptic reminders that the scope of another person's soul could never be fully surveyed.

As he drifted off, his father came to visit him, clothed in all his possible shapes.

The scientific method entails two assumptions that are so basic that, even if you spell them out, they are still difficult to keep in mind. First: that the observer stays the same while the world changes. Second: that cause precedes effect.But the very nature of the experiment we are conducting means that the second of these assumptions is thrown into doubt. We are deliberately attempting to engineer an event in which effect chronologically precedes cause.If one of these assumptions is under threat, why not the other?

First, the idea of the multiverse is essentially the fantasy of preserving perfect information. One of the hard things to deal with in life is the fact that you destroy potential information whenever you make a decision. You could even say that's essentially what regret is: a profound problem of incomplete information. If you select one thing on a diner's menu, you can't know what it would have been like to taste other things on it, right then, right there. When you marry one person, you give up the possibility of knowing what it would have been like to have married any number of others. But if the multiverse exists, you can at least imagine there's another version of you who's eating that other thing you thought about ordering, or who's married to that other man you only went on two dates with. Even if you'll never see all the information for yourself, at least you'll be able to tell yourself that it's

There was a graduate student in my cohort, this guy I dated, who told me he came to realize that doing physics is like this: there's a concrete wall twenty feet thick, and you're on one side, and on the other side is everything worth knowing. And all you have is a spoon. So you just have to take a spoon and start scraping at the wall: no other way. He works in a bookstore now.But I think of it this way. There is a jigsaw puzzle. It's infinitely large, with no edges or corners to help you out. We have to put it together: it's our duty. We will never finish, but we have to find our satisfactions where we can: when we place two pieces together that suggest we may have found the place where the sky touches the sea, or when we discover a piece that is beautiful in and of itself, that has an unusual color or a glimpse of an unexpected pattern. And the pieces that do not join together also tell you something. If there are very few eureka moments, then at least there are a thousand little failures, that point the way toward a hundred little joys.

But I cannot accept a vision of You as an engineer who spends His days maintaining the machine of morality. I cannot take the idea of You as an optimizer, introducing evil into human affairs in an attempt to create the best of all possible worlds. I cannot bear this cold mathematician's God who sees all the universe as nothing more than an elaborate problem to be solved. Such a world is a world with no meaning, one in which one history is no more or less preferable to any other.
