From the acclaimed author of
The Information
and
Chaos,
here is a mind-bending exploration of time travel: its subversive origins, its evolution in literature and science, and its influence on our understanding of time itself.
The story begins at the turn of the previous century, with the young H. G. Wells writing and rewriting the fantastic tale that became his first book and an international sensation:
The Time Machine
. It was an era when a host of forces was converging to transmute the human understanding of time, some philosophical and some technological: the electric telegraph, the steam railroad, the discovery of buried civilizations, and the perfection of clocks. James Gleick tracks the evolution of time travel as an idea that becomes part of contemporary culture—from Marcel Proust to
Doctor Who,
from Jorge Luis Borges to Woody Allen. He investigates the inevitable looping paradoxes and examines the porous boundary between pulp fiction and modern physics. Finally, he delves into a temporal shift that is unsettling our own moment: the instantaneous wired world, with its all-consuming present and vanishing future.

To Beth, Donen,
and Harry
Your now is not my now; and again, your then is not my then; but my now may be your then, and vice versa. Whose head is competent to these things?
—Charles Lamb (1817)
The fact that we occupy an ever larger place in Time is something that everybody feels.
—Marcel Proust (1927?)
And tomorrow
Comes. It’s a world. It’s a way.
—W. H. Auden (1936)

Being young, I was skeptical of the future, and saw it as a matter of potential only, a state of things that might or might not arise and probably never would.

A MAN STANDS AT
the end of a drafty corridor, a.k.a. the nineteenth century, and in the flickering light of an oil lamp examines a machine made of nickel and ivory, with brass rails and quartz rods—a squat, ugly contraption, somehow out of focus, not easy for the poor reader to visualize, despite the listing of parts and materials. Our hero fiddles with some screws, adds a drop of oil, and plants himself on the saddle. He grasps a lever with both hands. He is going on a journey. And by the way so are we. When he throws that lever, time breaks from its moorings.
The man is nondescript, almost devoid of features—“grey eyes” and a “pale face” and not much else. He lacks even a name. He is just the Time Traveller: “for so it will be convenient to speak of him.”
Time
and
travel:
no one had thought to join those words before now. And that machine? With its saddle and bars, it’s a fantasticated bicycle. The whole thing is the invention of a young enthusiast named Wells, who goes by his initials, H. G., because he thinks that sounds more serious than Herbert. His family calls him Bertie. He is trying to be a writer. He is a thoroughly modern man, a believer in socialism, free love, and bicycles.
*1
A proud member of the Cyclists’ Touring Club, he rides up and down the Thames valley on a forty-pounder with tubular frame and pneumatic tires, savoring the thrill of riding his machine: “A memory of motion lingers in the muscles of your legs, and round and round they seem to go.” At some point he sees a printed advertisement for a contraption called Hacker’s Home Bicycle: a stationary stand with rubber wheels to let a person pedal for exercise without going anywhere. Anywhere through space, that is. The wheels go round and time goes by.
The turn of the twentieth century loomed—a calendar date with apocalyptic resonance. Albert Einstein was a boy at gymnasium in Munich. Not till 1908 would the Polish-German mathematician Hermann Minkowski announce his radical idea: “Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.” H. G. Wells was there first, but unlike Minkowski, Wells was not trying to explain the universe. He was just trying to gin up a plausible-sounding plot device for a piece of fantastic storytelling.
Nowadays we voyage through time so easily and so well, in our dreams and in our art. Time travel feels like an ancient tradition, rooted in old mythologies, old as gods and dragons. It isn’t. Though the ancients imagined immortality and rebirth and lands of the dead time machines were beyond their ken. Time travel is a fantasy of the modern era. When Wells in his lamp-lit room imagined a time machine, he also invented a new mode of thought.
Why not before? And why now?

THE TIME TRAVELLER BEGINS
with a science lesson. Or is it just flummery? He gathers his friends around the drawing-room fire to explain that everything they know about time is wrong. They are stock characters from central casting: the Medical Man, the Psychologist, the Editor, the Journalist, the Silent Man, the Very Young Man, and the Provincial Mayor, plus everyone’s favorite straight man, “an argumentative person with red hair” named Filby.
“You must follow me carefully,” the Time Traveller instructs these stick figures. “I shall have to controvert one or two ideas that are almost universally accepted. The geometry, for instance, that they taught you at school is founded on a misconception.” School geometry—Euclid’s geometry—had three dimensions, the ones we can see: length, width, and height.
Naturally they are dubious. The Time Traveller proceeds Socratically. He batters them with logic. They put up feeble resistance.
“You know of course that a mathematical line, a line of thickness
nil,
has no real existence. They taught you that? Neither has a mathematical plane. These things are mere abstractions.”
“That is all right,” said the Psychologist.
“Nor, having only length, breadth, and thickness, can a cube have a real existence.”
“There I object,” said Filby. “Of course a solid body may exist. All real things—”
“So most people think. But wait a moment. Can an
instantaneous
cube exist?”
“Don’t follow you,” said Filby [the poor sap].
“Can a cube that does not last for any time at all, have a real existence?”
Filby became pensive. “Clearly,” the Time Traveller proceeded, “any real body must have extension in
four
directions: it must have Length, Breadth, Thickness, and—Duration.”
Aha! The fourth dimension. A few clever Continental mathematicians were already talking as though Euclid’s three dimensions were not the be-all and end-all. There was August Möbius, whose famous “strip” was a two-dimensional surface making a twist through the third dimension, and Felix Klein, whose loopy “bottle” implied a fourth; there were Gauss and Riemann and Lobachevsky, all thinking, as it were, outside the box. For geometers the fourth dimension was an unknown direction at right angles to all our known directions. Can anyone visualize that? What direction is it? Even in the seventeenth century, the English mathematician John Wallis, recognizing the algebraic possibility of higher dimensions, called them “a Monster in Nature, less possible than a Chimaera or Centaure.” More and more, though, mathematics found use for concepts that lacked physical meaning. They could play their parts in an abstract world without necessarily describing features of reality.
