“A STAGGERING NOVEL! If you ever thought you understood time, you’ll be quickly disillusioned when you read Manifold: Time.”


“Reading Manifold: Time is like sending your mind to the gym for a brisk workout. If you don’t feel both exhausted and exhilarated when you’re done, you haven’t been working hard enough.”
The New York Times Book Review

–The Washington Post

The scope of the book is awesome. . . . [Baxter] expertly captures the giddy rush of future shock.”

“If ideas were radioactive particles, Manifold: Time would be a block of plutonium. The story takes off at near-lightspeed . . . Baxter treats readers to a gallery of cosmic wonders, including a haunting look at a future so unimaginably distant that beings of that era see our own time as part of the hot, bright aftermath of the Big Bang.”
Science Fiction Weekly

“Recommended . . . Discoveries and adventures abound . . . Most science fiction writers wish to make their readers feel the thrill, the sense of wonder, that so marked SF’s youth that the genre still claims it as a sort of trademark, even though it is scarcely to be found today. Baxter succeeds as very few do.”

“Baxter sets a crackling pace. . . . Visionary [and] extravagantly imagined, Time places Baxter firmly in the tradition of Arthur C. Clarke and Isaac Asimov.”
The London Times

Recommended by Locus Magazine

Baxter tops the old master [H.G. Wells] by taking us
on a journey of trillions of years.”
For Him Magazine

“[Baxter’s] originality is incontrovertible. The technical detail is as adroit as his unparalleled narrative skills. . . . [Filled] with the imaginative grandeur and much sought-after ‘sense of wonder’ that only the finest science fiction can produce.”
News International

“Baxter brings an inventive twist to the standard sf themes of time and space travel as he explores the intricate relationships between mind and matter. His use of multiple points of view creates a level of personal immediacy that provides a human counterpoint to a tale of cosmic proportions.”
–Library Journal

“A treat for readers who revel in scientific extrapolation.”
–Kirkus Reviews

[Baxter] manages to take the most esoteric cosmological ideas and mesh them into a fast-paced novel. . . . Black holes; superstring theory; the heat death of the universe–he wraps them all together and makes them accessible. . . . It’s time for Baxter to take his place alongside Asimov and Heinlein.”
Edge magazine

“A blockbuster novel which is not content to restrict its ambition to just one universe . . . Thoroughly enjoyable.”
The Matrix

“Baxter is the equal of Gregory Benford or Greg Bear when it comes to describing spectacular astronomical phenomena . . . and he shares with Arthur C. Clarke and Olaf Stapledon the ability to portray enormous vistas of time and space to great effect. . . . There’s plenty here to spark the veteran SF reader’s sense of wonder.”
–Publishers Weekly


“Arthur C. Clarke, Isaac Asimov, and Robert Heinlein succeeded . . . and now Stephen Baxter joins their exclusive ranks, writing science fiction in which the science is right.”

Reid Malenfant   You know me. And you know I'm a space cadet.

You know I've campaigned for, among other things, private mining expeditions to the asteroids. In fact, in the past I've tried to get you to pay for such things. I've bored you with that often enough already, right?

So tonight I want to look a little farther out. Tonight I want to tell you why I care so much about this issue that I devoted my life to it.

The world isn't big enough any more. You don't need me to stand here and tell you that. We could all choke to death, be extinct in a hundred years.

Or we could be on our way to populating the Galaxy.

Yes, the Galaxy. Want me to tell you how?

Turns out it's all a question of economics.

Let's say we set out to the stars. We might use ion rockets, solar sails, gravity assists. It doesn't matter.

We'll probably start as we have in the Solar System, with automated probes. Humans may follow. One percent of the helium-3 fusion fuel available from the planet Uranus, for example, would be enough to send a giant interstellar ark, each ark containing a billion people, to every star in the Galaxy. But it may be cheaper for the probes to manufacture humans in situ, using cell synthesis and artificial womb technology.

The first wave will be slow, no faster than we can afford. It doesn't matter. Not in the long term.

When the probe reaches a new system, it phones home, and starts to build.

Here is the heart of the strategy. A target system, we assume, is uninhabited. We can therefore anticipate massive exploitation of the system's resources, without restraint, by the probe. Such resources are useless for any other purpose, and are therefore economically free to us.

I thought you'd enjoy that line. There's nothing an entre- preneur likes more than the sound of the word free.

More probes will be built and launched from each of the first wave of target stars. The probes will reach new targets; and again, more probes will be spawned, and fired onward. The volume covered by the probes will grow rapidly, like the expansion of gas into a vacuum.

Our ships will spread along the spiral arm, along lanes rich with stars, farming the Galaxy for humankind.

Once started, the process will be self-directing, self-financing. It would take, the double-domes think, ten to a hundred million years for the colonization of the Galaxy to be completed in this manner. But we must invest merely in the cost of the initial generation of probes.

Thus the cost of colonizing the Galaxy will be less, in real terms, than that of our Apollo program of fifty years ago.

This vision isn't mine alone. It isn't original. The rocket pioneer Robert Goddard wrote an essay in 1918--ninety-two years ago--called The Ultimate Migration, in which he imagined space arks built from asteroid materials carrying our far-future descendants away from the death of the sun. The engineering detail has changed; the essence of the vision hasn't.

We can do this. If we succeed, we will live forever.

The alternative is extinction.

And, people, when we're gone, we're gone.

As far as we can see we're alone, in an indifferent universe. We see no sign of intelligence anywhere away from Earth. We may  be the first. Perhaps we're the last. It took so long for the Solar System to evolve intelligence it seems unlikely there will be others, ever.

If we fail, then the failure is for all time. If we die, mind and consciousness and soul die with us: hope and dreams and love, everything that makes us human. There will be nobody even to mourn us.

To be the first is an awesome responsibility. It's a responsibility we must grasp.

I am offering you a practical route to an infinite future for humankind, a future of unlimited potential. Someday, you know it, I'll come back to you again for money: seedcorn money, that's all, so we can take a first step--self-financing even in the medium term--beyond the bounds of Earth. But I want you to see why I'll be doing that. Why I must.

We can do this. We will do this. We're on our own. It's up to us.

This is just the beginning. Join me.

Thank you.


This is what I have learned, Malenfant. This is how it is, how it was, how it came to be.

In the afterglow of the Big Bang, humans spread in waves across the universe, sprawling and brawling and breeding and dying and evolving. There were wars, there was love, there was life and death. Minds flowed together in great rivers of consciousness, or shattered in sparkling droplets. There was immortality to be had, of a sort, a continuity of identity through replication and confluence across billions upon billions of years.

Everywhere they found life.

Nowhere did they find mind--save what they brought with them or created--no other against which human advancement could be tested.

With time, the stars died like candles. But humans fed on bloated gravitational fat, and achieved a power undreamed of in earlier ages.

They learned of other universes from which theirs had evolved. Those earlier, simpler realities too were empty of mind, a branching tree of emptiness reaching deep into the hyperpast.

It is impossible to understand what minds of that age--the peak of humankind, a species hundreds of billions of times older than humankind--were like. They did not seek to acquire, not to breed, not even to learn. They had nothing in common with us, their ancestors of the afterglow.

Nothing but the will to survive. And even that was to be denied them by time.

The universe aged: indifferent, harsh, hostile, and ultimately lethal.

There was despair and loneliness.

There was an age of war, an obliteration of trillion-year memories, a bonfire of identity. There was an age of suicide, as the finest of humanity chose self-destruction against further purposeless time and struggle.

The great rivers of mind guttered and dried.

But some persisted: just a tributary, the stubborn, still unwilling to yield to the darkness, to accept the increasing confines of a universe growing inexorably old.

And, at last, they realized that this was wrong. It wasn't supposed to have been like this.

Burning the last of the universe's resources, the final downstreamers--dogged, all but insane--reached to the deepest past. And--oh.

Watch the Moon, Malenfant. Watch the Moon. It's starting--
