—before she had time to think about it here was still another binary pair, this time much further from the ship, with a bright, hot blue star traversing the decaying hulk of a dim red giant. She saw how the giant hung behind the blue star like smoke behind a diamond—
—when she was whisked away yet again and now, before her, hung a softly shimmering globe of light: a planetary nebula, she recognized, the expanding corpse of a red giant, blown apart by its bird-induced superwind, but before—
—she could wonder if Sol would one day look like this, the nebula had gone to be replaced by an anonymous, distant star field which—
—vanished, because now she was surrounded by a dim, red smog; she was actually
inside a
giant star, she realized,
inside
its cooling outer flesh and—
—that was gone too, replaced by a huge, ragged nebula -
a supernova site? -
which—
—imploded and—
—a star loomed at her, swollen, ruddy, achingly like Sol, but not Sol, and—

and - and - andandand—
The stars were a huge, celestial barrage around her head. Beyond the immediate battering of light, the more distant constellations slid across space, elegant, remote, like trees in a forest.
Spinner sat rigidly in her crash-couch, letting the silent explosions of starlight wash across her cage.
. . . And, abruptly as it had begun, the barrage of starfields thinned out, diminished, vanished. Before the nightfighter now was only a uniform, restful darkness; a soft pink light, from some source behind her, played over the surfaces of the cage.
It’s over.
Spinner-of-Rope felt herself slump in her couch. She felt as if her bones had turned to water. She cradled her visor in her glove, shutting out the Universe, and sucked on an orange juice nipple; the sharp, homely taste seemed to fill up her head.
She felt herself retreat into the small cosmos of her own body once more, into the recesses of her own head.
It’s comfortable in here
, she thought groggily.
Maybe I should never come out again . . .
‘Spinner-of-Rope.’ Louise’s voice, sounding very tender. ‘How are you feeling?’
Spinner sucked resentfully on her orange juice. ‘About as good as you’d expect. Don’t ask stupid questions, Louise.’
‘You did bloody well to withstand that.’
Spinner grunted. ‘How do you know I
did
withstand it?’
‘Because I didn’t hear you scream. And because my telltales are showing me that you aren’t chewing the inside of your helmet. And—’
‘Louise, I knew what to expect.’
‘Maybe. But it was still
inhuman
. A Xeelee might have enjoyed that ride . . . People, it seems, need to work on a smaller scale.’
‘You’re telling me.’
‘ . . . When you’re ready, take a look behind you.’
Spinner lifted her face from the nipple. The pinkish light from the source behind her still played over the surfaces of the waldoes, the crumpled suit fabric over her thighs.
She loosened her restraints, carefully, and turned around.
There was a
ceiling
of light above her. It was an immense plane of curdled smoke: lurid red at its heart and with violent splashes of colours - yellow and orange and blue - further out. The plane was foreshortened, so that she stared across ridged lanes of gas towards the bulging, pregnant centre. Smoky gas was wrapped around the core in lacy spirals of colour.
The plane of light receded, almost imperceptibly slowly, from the ship. The plane was a roof, and the nightfighter - with its precious burden of people, and all the hopes of humanity - was a fly, diving down and away from that immense surface.
‘Louise, it’s
beautiful
. I had no idea . . .’
‘Do you understand what you’re seeing, Spinner-of-Rope?’ Louise’s voice sounded fragile, as if she were struggling with the enormity of what she was saying. ‘Spinner, you’re looking up at our Galaxy -
from the outside
. And that’s why that barrage of stars has finished . . . Our Galaxy’s disc is only around three thousand light-years thick. Travelling obliquely to the plane, we were out of it in just a couple of minutes.’
The nightfighter had plunged out of the Galaxy at a point about two-thirds of the way along a radius from the centre to the rim. The ship was going to pass under the centre of the disc; that bloated bulge of crimson light would look like some celestial chandelier, thousands of light-years across, hanging over her head. Spiral arms - cloudy, streaming - moved serenely over her head. There were blisters of gas sprinkled along the arms, she saw, bubbles of swollen colour.
‘Spinner, the disc is a hundred thousand light-years across. It will take us just fifty minutes to traverse its width . . .’
Spinner heard Louise turn away and mumble something.
‘What was that?’
‘Your kid sister. Painter-of-Faces. She asked why we aren’t seeing relativistic distortion.’
Spinner grinned. ‘Tell her not to bother us with such stupid questions.’
‘We aren’t all hardened space pilots like you, Spinner-of-Rope . . .’
There was no relativistic distortion - no starbow, no red or blue shift - because the nightfighter wasn’t moving
through
the Universe. The ‘fighter was hopping from point to point - like a tree frog, Spinner thought, leaping between bromeliads. And at the end-point of each jump, the ship was stationary - just for a second - relative to the Galaxy.
So, no blue shift.
But the nightfighter was falling out of the Galaxy at an effective velocity of millions of times lightspeed. It was the
frequency
of the jumps which gave Spinner this illusion of constant, steady motion.
It was working out, just as planned.
We’re
making
it, Louise,’ Spinner said. ‘We’re making this
happen
.’
‘Yes . . .
But
—’
Spinner let out a mock groan. ‘But now you’re going to tell me how things just ain’t what they used to be,
again
, aren’t you?’
‘Well, it’s true, Spinner,’ Louise said angrily. ‘Look at it . . . Even from this distance, outside the Galaxy, you can see the handiwork of those damn photino birds.’
The Galaxy contained two main classes of stars, Louise told Spinner.
Population I
stars, like the Sun, had evolved in the hydrogen-rich spiral arms, away from the centre. Some of these - like the blue supergiants - had been hundreds of times larger than the Sun, blazing out their energy in a short, insanely profligate youth. Population I stars tended to explode, enriching the interstellar medium - and later generations of stars - with the complex products of their nucleosynthesis.
By contrast,
Population II
stars had formed in regions where hydrogen fuel was in scarce supply: in the old regions close to the core, or in the clusters outside the main disc. The II stars were more uniform in size, and - by the era of the earliest human astronomy - had already been old, characterized by jostling herds of red giants.
‘Look at that disc,’ Louise snapped. ‘I don’t suppose the damn birds had to do much to the dull, stable Population IIs; those things were half-dead already. But look - oh, look at the spiral arms . . .’
Spinner saw how ragged the spirals were, disrupted by the blisters of yellow-red light which swelled across the lanes of dust.
‘Those blisters are supernova remnants,’ Louise said bitterly. ‘Spinner, not every star would respond as peacefully to the photino birds’ engineering as did our poor old Sun. A lot of the more spectacular, and beautiful, Population I stars would simply explode, tearing themselves apart . . . Probably the birds set off chain reactions of supernovae, with the wreckage of one star destabilizing another.’
Spinner stared up at the wreckage of the disc, the muddled spiral arms.
. . . We’re already forty thousand light-years below the disc, Spinner
, her companion said.
The light you’re seeing now left the stars forty millennia ago . . . Think of that. Forty thousand years before my birth, humans were still shivering on the edges of glaciers, making knives out of bits of stone. And the further we travel, with every second, the light is getting older: Spinner-of-Rope, you’re taking us through a hail of ancient light . . .
Spinner laughed. ‘You should have been a poet.’
‘What?’
‘ . . . Tell me what’s coming next, Louise.’
‘All right. Spinner, do you know what
a globular cluster
is?’
Spinner frowned. ‘I think so.’ She closed her eyes. ‘A stable ball of stars - perhaps a hundred thousand of them - orbiting around the main disc, in the Galactic halo.’
‘Right,’ Louise said. ‘They are Population II stars. And one particular cluster, called Omega Centauri, was one of the brightest clusters visible from old Earth.’
Spinner thought that over. ‘
Omega Centauri
. That name means it was in the line-of-sight of the Centaurus constellation.’
‘Right.’
‘You mean—’
‘We’re heading right for it. Keep your eyes tight shut, Spinner-of-Rope.’
Spinner turned, and looked ahead.
Beyond the fragile cage, giant stars ballooned at her, dazzling her with their billowing silence.

U
pright on their zero-gee scooters, Lieserl and Milpitas descended into the deep loading bay at the base of the
Northern
’s lifedome. Above Lieserl the maintenance bulkhead at the base of Deck Fifteen spread out, an improbable tangle of ducts, cables and tree roots.
From the corner of her eye, Lieserl watched Milpitas curiously. He looked down at the drop beneath his feet with undisguised dread. Milpitas had been a starship traveller for a thousand years, but he was so obviously a gravity-well dweller. He visibly suffered in this zero-gee environment, his instincts quite unadapted to the fact that even if his scooter failed completely he’d simply drift through the air, perfectly safely.
Beneath the thick layer of dank, empty air into which she was descending, the base of the
Northern
’s lifedome had been turned transparent. The base appeared to Lieserl as a pool of cool darkness - and there, pinned against the underside of the lifedome base, like some immense insect immersed in a pond, was the slender form of the Xeelee nightfighter which bore them through space. Its sycamore-seed wings looked somehow darker even than the emptiness between stars.
The Planner turned to her stiffly and smiled. ‘You look - uncomfortable - on that scooter.’
She suppressed a grin.
Me
?

Uncomfortable? Not really.’ She clicked her fingers and her scooter disappeared. She smiled at Milpitas, feeling mischievous. She did a back flip in the air, rolling twice; the clear floor beneath her wheeled across her vision.
She finished up falling alongside Milpitas once more. ‘I don’t feel uncomfortable, ’ she said. ‘Just - well, a little foolish. Sometimes I feel these Virtual masks Mark sets up for me are a little forced.’
Milpitas had turned away from her antics, his face pale; he gripped the handles of his scooter so hard his knuckles were white.
Hastily she called subvocally for the return of her Virtual scooter. I’m sorry,’ she said, sincerely. ‘I guess I shouldn’t have done that.’
She saw how the sweat glistened on the patchwork scars of his brow, but he determinedly held himself erect on his scooter. ‘Don’t apologize,’ he said primly. ‘We’re here on an inspection tour . . . to consider the disposition of
the ship
, not my well-being.’
So, after that brief moment of human frailty, Milpitas was back in his shell. She turned away, vaguely disappointed.
They were approaching the base of the loading bay, now. Lieserl could see the twin small jets of her scooter reflected in the clear floor; like attracting stars, she converged with her own image - in fact it was an image of an image, she thought wryly; the processors which sustained her were doing a good job with their Virtual reality creation today.
Milpitas, with a tense flick of his bony, scarred wrist, levelled off and began to sail parallel to the surface. Lieserl followed, a few feet behind.
Beneath the dome base, the Xeelee nightfighter spread its construction-material wings, huge, dormant.
‘Good morning, Spinner-of-Rope,’ Louise said.
Spinner stretched. Allowing herself to wake up slowly, she sucked fortified fruit juice from her helmet nipples and let the environment suit clean her skin with blasts of ultrasonics; she felt a warm trickle of urine enter her catheter.
She grunted in reply to Louise.
It was Spinner’s tenth day in the nightfighter cage.
She loosened her restraints and looked around - and found herself staring into intergalactic emptiness. In the distance were patches of muddy light which could have been galaxies, or clusters of galaxies - so remote that even at the ‘fighter’s immense speed of three million light-years a day, she could make out no discernible movement.
Spinner slumped back into her couch. ‘Lethe. Another day in the middle of this grey, lifeless desert,’ she said sourly.
Louise - watching, Spinner knew, from her encampment on the
Northern
’s forest Deck - laughed, sounding sympathetic. ‘But today should be a little more interesting than most, Spinner-of-Rope. We’ve reached a milestone. Or rather, a
mega-light-year-stone
. . .’
‘We have?’
‘After ten days, we’ve come thirty million light-years from Sol. Spinner, we’ve reached the centre of the Virgo Cluster - the supercluster of galaxies of which our Galaxy is a member. Way behind you is a little patch of light: that’s the Local Group - three million light-years across, the small cluster dominated by our Galaxy and the Andromeda galaxy. And to your left, at about eleven o’clock, you’ll see the centre of the Virgo Cluster itself: that massive group of several thousand bright galaxies. They
used
to be bright, anyway . . .’
