The Time Traveler's Almanac

Earth lies dark and unpopulated once more, for humanity – as always – has gone extinct. Of the great works in Jupiter orbit few traces remain. The great ships have gone, the shipyards have long since been deorbited into the swirling chaos of the gas giant’s atmosphere, and the malformed, warped transfer bodies have been cannibalized and restored to their original purpose.

Five small moons have disappeared, and slowly healing gouges show the sites of huge mining works on Io and Europa, but by the time the Stasis reseed Earth (two-thirds of a million years hence) even the slow resurfacing of Europa’s icy caul will have obscured the signs of industry. It may be thousands of years after that before anybody notices.

SLIDE 5.

Twenty million years pass, and the galaxy slowly lights up with a glare of coherent light, waste energy from the communications traffic between the inhabited worlds.

The first generation colonies have long since guttered into senescence and extinction; so have the third and fourth generations. Of the first generation, barely one in five prospered – but that was sufficient. Those that live spawn prolifically. Planets are common, rocky terrestrial bodies far from rare, and even some of the more exotic types (water giants, tide-locked rocky giants in orbit around red dwarfs, and others) are amenable to human purpose. Where no planets are available, life is harder, prone to sudden extinction events: nobody survives the collapse of civilization aboard a space colony. But the tools and technologies of terraforming are well-known, and best practice, of a kind, develops. Many of the dwellers have adapted to their new habitats so well that they’re barely recognizable as primates anymore, or even mammals.

SLIDE 6.

Three billion years pass.

Two huge, glittering clouds of sentience fall through each other, a magnificently coordinated flypast of fleets of worlds meshing across the endless void. Shock waves thunder through the gas clouds, and millions of massive, short-lived new stars ignite and detonate like firecrackers. The starburst is indeed enormous. But for the most part, the inhabited worlds are safe: swarms of momentum-transfer robots, their numbers uncountable, work for millions of years ahead of and behind the event to direct the closest encounters. Emergent flocking rules and careful plans laid far in advance have steered colonies clear of the high-risk territories, marshaling brown dwarfs as dampers and buffers to redirect the tearaway suns – and both galaxies are talking to each other, for the expanding sphere of sentience now encompasses the entire Local Group.

Earth is no longer inhabited in this epoch; but the precious timegate remains, an oracular hub embedded in a cluster of exotic artificial worlds, conducting and orchestrating the dance of worlds.

There are now a hundred million civilizations within the expanding bubble of intelligence, each with an average population of billions. They are already within an order of magnitude of the Stasis’s ultimate population, and they are barely a thousandth of its age. The universe, it appears, has started to wake up.

The Kindest Lies

They walked along a twisting path between walls of shrubs and creepers, and a few short trees, growing from mounds of damp-smelling soil. The path appeared to be of old sandstone, shot through with seams of a milky rock like calcite: appearances were deceptive.

“You played me like a flute,” said Pierce. He held his hands behind his back, as was his wont, keeping an arm’s reach aside from her.

“I did not!” Her denial was more in hurt than in anger. “I didn’t know about this until he, you, recruited me.” Her boot scuffed a rock leaning like a rotten tooth from the side of a herbaceous border: tiny insects scuttled from her toes, unnoticed. “I was still in training. Like you, when you were tapped for, for other things.”

They walked in silence for a minute, uphill and around a winding corner, then down a flight of steps cut into the side of a low hill.

“If this is all simply an internal adjustment, why doesn’t Internal Affairs shut everything down?” he asked. “They must know who is involved…”
