Time Travel. A History полностью

Now the conversation begins to get complicated. The Doctor must persuade Sally (and us) that he is a time traveler who has been separated from his time machine (a blue phone box) and hurled back to 1969, that he has been trying to send her messages through an old house and various long-lived human couriers, and that now they are talking to each other via a recording he has concealed on seventeen DVDs, all of which she happens to own in 2007. Larry has heard the Doctor’s side of the conversation many times. For him it is preordained: bits laser-engraved on a plastic disc. Finally he is hearing the stereophonic version. Sally talks to the screen, the Doctor talks from the screen, and Larry writes it all down.

SALLY: I’ve seen this bit before.

THE DOCTOR: Quite possibly.

SALLY: Nineteen sixty-nine, that’s where you’re talking from?

THE DOCTOR: Afraid so.

SALLY: But you’re replying to me. You can’t know exactly what I’m going to say, forty years before I say it.

THE DOCTOR [pedantically]: Thirty-eight.

How is this possible? Let’s review the rules of time travel. Sally is right: he can’t hear her. That’s an illusion. It’s really quite simple, he explains. He possesses a transcript of the entire conversation and is reading his lines, like an actor.^*3

SALLY: How can you have a copy of the finished transcript? It’s still being written.

THE DOCTOR: I told you. I’m a time traveler. I got it in the future.

SALLY: Okay, let me get my head round this. You’re reading aloud from a transcript of a conversation you’re still having.

THE DOCTOR: Yeah. Wibbly wobbly, timey wimey.

The TARDIS still needs to reunite with the Doctor. The Doctor still needs to get his hands on the transcript. Before the intricate machinery of this plot is complete, Sally, who now understands the whole story, will have to meet a version of the Doctor who has not yet grasped it. Now her past is his future. “Blink” is all the paradoxes rolled together with a Möbius twist. It’s Predestination and Free Will conversing in real time, via technology new for one and obsolete for the other.

By 2007 the internet was in full flow, but it plays no obvious part in the story. Cyberspace is an offstage presence—the dog that doesn’t bark in the night. This unusual episode of Doctor Who expressed something about our complexified relationship with time. Nowadays, Sally Sparrow’s in-box will be overflowing with thousands of emails, mingling past and present, which she may view threaded or flat, and the number only grows, and she is entirely capable of carrying on multiple conversation threads, SMS and MMS, emoji and video, simultaneous and asynchronous, with two participants or many, and meanwhile, with or without earbuds, she hears voices and glimpses screens everywhere, in waiting rooms and on signposts, and if she pauses to think, she may have trouble placing all the information in proper temporal sequence—wibbly wobbly, timey wimey—but who pauses to think?

WHEN THE BROTHERS Louis and Auguste Lumière invented the cinématographe in the 1890s, they did not begin by filming actors dressed in costumes. They did not make fictional movies. They trained operators in the new technology and sent Clément and Constant and Félix and Gaston and many more across the globe to record snippets of real life. Naturally they filmed workers leaving their own factory—who could resist La sortie de l’usine Lumière à Lyon?—but by 1900 they were filming a cockfight in Guadalajara, and the foot traffic on Broadway, and men smoking opium in what is now Vietnam. Audiences flocked to see these scenes of faraway live action. The creation of these images marks an event horizon. When we look back, the pre-1900 past is less visible. It’s good we have books.

So much of the world comes to us on screens now, with sound as lifelike as the picture. The screens range farther than anyone could ever see unaided. Who is to say that these are not time gates? People “stream” music to us and video, the tennis match we’re watching may or may not be “live,” the people in the stadium watching the instant replay on the stadium screen, which we see repeated on our screen, may have done that yesterday, in a different time zone. Politicians record their responses to speeches they have not yet seen, for instant broadcast. If we confuse the real world with our many virtual worlds, it’s because so much of the real world is virtual. For many people, there is no personal memory of a time without screens. So many windows, so many clocks.
