From the intonation of his voice, from the nuances
of his speech, she tried to gain some glimpse of who it was
here disguised as her father. She bad an enormous amount of
direct experience with human beings; the Stationmasters had
less than a day's. Could she not discern something of their
true nature beneath this amiable and informative facade? But
she couldn't. In the content of his speech he was, of
course, not her father, nor did he pretend to be. But in
every other respect he was uncannily close to Theodore F.
Arroway, 1924-1960, vendor of hardware, loving husband and
father. If not for a continuous effort of will, she knew she
would be slobbering over this, this. . . copy. Part of her
kept wanting to ask him how things had been since he had
gone to Heaven. What were his views on Advent and Rapture?
Was anything special in the works for the Millennium? There
were human cultures that taught an afterlife of the blessed
on mountaintops or in clouds, in caverns or oases, but she
could not recall any in which if you were very, very good
when you died you went to the beach.
"Do we have time for some questions before . . .
whatever it is we have to do next?"
"Sure. One or two anyway." `Tell me about your
transportation system."
"I can do better than that," he said. "I can show
you. Steady now."
An amoeba of blackness leaked out from the zenith,
obscuring Sun and blue sky. "That's quite a trick," she
gasped. The same sandy beach was beneath her feet. She dug
her toes in. Overhead ... was the Cosmos. They were, it
seemed, high above the Milky Way Galaxy, looking down on its
spiral structure and falling toward it at some impossible
speed. He explained matter-of-factly, using her own familiar
scientific language to describe the vast pinwheel-shaped
structure. He showed her the Orion Spiral Arm, jh which the
Sun was, in this epoch, embedded. Interior to it, in
decreasing order of mythological significance, were the
Sagittarius Arm, the Norma/Scutum Arm, and the Three
Kiloparsec Arm.
A network of straight lines appeared, representing
the transportation system they had used. It was like the
illuminated maps in the Paris Metro. Eda had been right.
Each station, she deduced, was in a star system with a
low-mass double black hole. She knew the black holes
couldn't have resulted from stellar collapse, from the
normal evolution of massive star systems, because they were
too small. Maybe they were primordial, left over from the
Big Bang, captured by some unimaginable starship and towed
to their designated station. Or maybe they were made from
scratch. She wanted to ask about this, but the tour was
pressing breathlessly onward.
There was a disk of glowing hydrogen rotating about
the center of the Galaxy, and within it a ring of molecular
clouds rushing outward toward the periphery of the Milky
Way. He showed her the ordered motions in the giant
molecular cloud complex Sagittarius B2, which had for
decades been a favorite hunting ground for complex organic
molecules by her radio-astronomical colleagues on Earth.
Closer to the center, they encountered another giant
molecular cloud, and then Sagittarius A West, an intense
radio source that Ellie herself had observed at Argus.
And just adjacent, at the very center of the Galaxy,
locked in a passionate gravitational embrace, was a pair of
immense black holes. The mass of one of them was fivemillion
suns. Rivers of gas the size of solar systems were pouring
down its maw. Two colossal-she ruminated on the limitations
of the languages of Earth-two supermas-ive black holes are
orbiting one another at the center of the Galaxy. One had
been known, or at least strongly suspected. But two?
Shouldn't that have shown up as a Doppler displacement of
spectral lines? She imagined a sign under one of them
reading Entrance and under the other exit. at the moment,
the entrance was in use; the exit was merely there.
And that was where this Station, Grand Central
Station, was-just safely outside the black holes at the
center of the Galaxy. The skies were made brilliant by
millions of nearby young stars; but the stars, the gas, and
the dust were being eaten up by the entrance black hole. "It
goes somewhere, right?" she asked. "Of course."
"Can yon tell me where?"
"Sure. All this stuff winds up in Cygnus A." Cygnus
A was something she knew about. Except only for a nearby
supernova remnant in Cassiopeia, it was the brightest radio
source in the sides of Earth. She had calculated that in one
second Cygnus A produces more energy than the Sun does in
40,000 years. The radio source was 600 million light-years
away, far beyond the Milky Way, out in the realm of the
galaxies. As with many extragalactic radio sources, two
enormous jets of gas, fleeing apart at almost the speed of
tight, were making a complex web of Rankine-Hugoniot shock
fronts with the thin intergalactic gas-and producing in the
process a radio beacon that shone brightly over most of the
universe. All the matter in this enormous structure, 500,000
light-years across, was pouring out of a tiny, almost
inconspicuous point in space exactly midway between the
jets. "You're making Cygnus A?"
She half-remembered a summer's night in Michigan
when she was a girl. She had feared she would fall into the
sky. "Oh, it's not just us. This is a... cooperative project
ofmany galaxies. That's what we mainly do-engineering. Only
a . . . few of us are involved with emerging civilizations."
At each pause she had felt a kind of tingling in her
head, approximately in the left parietal lobe.
`There are cooperative projects between galaxies?"
she asked. "Lots of galaxies, each with a kind of Central
Administration? With hundreds of billions of stars in each
galaxy. And then those administrations cooperate. To pour
millions of suns into Centaurus . . . sorry, Cygnus A? The .
. . Forgive me. I'm just staggered by the scale. Why would
you do all this? Whatever for?"
"You mustn't think of the universe as a wilderness.
It hasn't been that for billions of years," he said. "Think
of it more as . . . cultivated." Again a tingling.
"But what for? What's there to cultivate?"
"The basic problem is easily stated. Now don't get
scared off by the scale. You're an astronomer, after all.
The problem is that the universe is expanding, and there's
not enough matter in it to stop the expansion. After a
while, no new galaxies, no new stars, no new planets, no
newly arisen lifeforms-just the same old crowd. Everything's
getting run-down. It'll be boring. So in Cygnus A we're
testing out the technology to make something new. You might
call it an experiment in urban renewal. It's not our only
trial run. Sometime later we might want to close off a piece
of the universe and prevent space from getting more and more
empty as the aeons pass. Increasing the local matter
density's the way to do it, of course. It's good honest
work." Like running a hardware store in Wisconsin. If Cygnus
A was 600 million light-years away, then astronomers on
Earth-or anywhere in the Milky Way for that matter-were
seeing it as it had been 600 million years ago. But on Earth
600 million years ago, she knew, there had hardly been any
life even in the oceans big enough to shake a stick at. They
were old. Six hundred million years ago, on a beach like
this one... except no crabs, no gulls, no palm trees. She
tried to imagine some microscopic plant washed ashore,
securing a tremulous toehold just above the water line,
while these beings were occupied with experimental
galactogenesis and introductory cosmic engineering.
"You've been pouring matter into Cygnus A for the
last six hundred million years?"
"Well, what you've detected by radio astronomy was
just some of our early feasibility testing. We're much
further along now."
And in due course, in another few hundred million
years she imagined, radio astronomers on Earth-if any-will
detect substantial progress in the reconstruction of the
universe around Cygnus A. She steeled herself for further
revelations and vowed she would not let them intimidate her.
There was a hierarchy of beings on a scale she had not
imagined. But the Earth had a place, a significance in that
hierarchy; they would not have gone to all this trouble for
nothing.
The blackness rushed back to the zenith and was
consumed; Sun and blue sky returned. The scene was the same:
surf, sand, palms, Magritte door, microcamera, frond, and
her... father.
"Those moving interstellar clouds and rings near the
center of the Galaxy-aren't they due to periodic explosions
around here? Isn't it dangerous to locate the Station here?"
"Episodic, not periodic. It only happens on a small
scale, nothing like the sort of thing we're doing in Cygnus
A. And it's manageable. We know when it's coming and we
generally just hunker down. If it's really dangerous, we
take the Station somewhere else for a while. This is all
routine, you understand."
"Of course. Routine. You built it all? The subways,
I mean. You and those other . . . engineers from other
galaxies?"
"Oh no, we haven't built any of it."
"I've missed something. Help me understand."
"It seems to be the same everywhere. In our case, we
emerged a long time ago on many different worlds in the
Milky Way. The first of us developed interstellar
space-flight, and eventually chanced on one of the transit
stations. Of course, we didn't know what it was. We weren't
even sore it was artificial until the first of us were brave
enough to slide down."
"Who's `we'? You mean the ancestors of your . . .
race, your species?"
"No, no. We're many species from many worlds.
Eventually we found a large number of subways-various ages,
various styles of ornamentation, and all abandoned. Most
were still in good working condition. All we did was make
some repairs and improvements."
"No other artifacts? No dead cities? No records of
what happened? No subway builders left?" He shook his head.
"No industrialized, abandoned planets?" He repeated the
gesture.
"There was a Galaxy-wide civilization that picked up
and left without leaving a trace-except for the stations?"
"That's more or less right. And it's the same in
other galaxies also. Billions of years ago, they all went
somewhere. We haven't the slightest idea where."
"But where could they go?" He shook his head for the
third time, but now very slowly.
"So then you're not . . ."
"No, we're just caretakers," he said. "Maybe someday
they'll come back."
"Okay, just one more," she pleaded, holding her
index finger up before her as, probably, had been her
practice at age two. "One more question."
"All right," he answered tolerantly. "But we only
have a few minutes left."
She glanced at the doorway again, and suppressed a
tremor as a small, almost transparent crab sidled by.
"I want to know about your myths, your religions.
What fills you with awe? Or are those who make the numinous
unable to feel it?"
"You make the numinous also. No, I know what you're
asking. Certainly we feel it. You recognize that some of
this is hard for me to communicate to you. But I'll give yon
an example of what you're asking for. I don't say this is it
exactly, but it'll give you a . . ."
He paused momentarily and again she felt a tingle,
this time in her left occipital lobe. She entertained the
notion that he was rifling through her neurons. Had he
missed something last night? If so, she was glad. It meant
they weren't perfect.
"... flavor of our numinons. It concerns pi, the
ratio of the circumference of a circle to its diameter. You
know it well, of course, and you also know you can never
come to the end of pi. There's no creature in the universe,
no matter how smart, who could calculate pi to the last
digit-because there is no last digit, only an infinite
number of digits. Your mathematicians have made an effort to
calculate it out to ..."
Again she felt the tingle.
"... none of you seem to know.. .. Let's say the
ten-billionth place. You won't be surprised to bear that
other mathematicians have gone further. Well,
eventually-let's say it's in the ten-to-the-twentieth-power
place-something happens. The randomly varying digits
disappear, and for an unbelievably long time there's nothing
but ones and zeros."
Idlymber of
zeros and ones? Is it a product of prime numbers?"
"Yes, eleven of them."
"You're telling me there's a message in eleven
dimensions hidden deep inside the number pi? Someone in the
universe communicates by ... mathematics? But ... helpme,
I'm really having trouble understanding you. Mathematics
isn't arbitrary. I mean pi has to have the same value
everywhere. How can you hide a message inside pi? It's built
into the fabric of the universe."
"Exactly." She stared at him.
"It's even better than that," he continued. "Let's
assume that only in base-ten arithmetic does the sequence of
zeros and ones show up, although you'd recognize that
something funny's going on in any other arithmetic. Let's
also assume that the beings who first made this discovery
had ten fingers. You see how it looks? It's as if pi has
been waiting for billions of years for ten-fingered
mathematicians with fast computers to come along. You see,
the Message was kind of addressed to us."
"But this is just a metaphor, right? It's not really
pi and the ten to the twentieth place? You don't actually
nave ten fingers."
"Not really." He smiled at her again. "Well, for
heaven's sake, what does the Message say?" He paused for a
moment, raised an index finger, and then pointed to the
door. A small crowd of people was excitedly pouring out of
it.
They were in a jovial mood, as if this were a
long-delayed picnic outing. Eda was accompanying a stunning
young woman in a brightly colored blouse and skirt, her hair
neatly covered with the lacy gele favored by Moslem women in
Yorubaland; he was clearly overjoyed to see her. From
photographs he had shown, Ellie recognized her as Eda's
wife. Sukhavati was holding hands with an earnest young man,
his eyes large and soulful; she assumed it was Surindar
Ghosh, Devi's long-dead medical-student husband. Xi was in
animated discourse with a small vigorous man of commanding
demeanor, he had drooping wispy mustaches and was garbed in
a richly brocaded and beaded gown. Ellie imagined him
personally overseeing the constrution of the funerary model
of the Middle Kingdom, shouting instructions to those who
poured the mercury.
Vaygay ushered over a girl of eleven or twelve, her
blond braids bobbing as she walked.
"This is my granddaughter, Nina . . . more or less.
My Grand Duchess. I should have introduced you before. In
Moscow."
Ellie embraced the girl. She was relieved that
Vaygay had not appeared with Meera, the ecdysiast. Ellie
observed his tenderness toward Nina and decided she liked
him more than ever. Over all the years she had known him, he
had kept this secret place within his heart well hidden.
"I have not been a good father to her mother," he
confided. `These days, I hardly see Nina at all."
She looked around her. The Stationmasters had
produced for each of the Five what could only be described
as their deepest loves. Perhaps it was only to ease the
barriers of communication with another, appallingly
different species. She was glad none of them were happily
chatting with an exact copy of themselves.
What if you could do this back on Earth? she
wondered. What if, despite all our pretense and disguise, it
was necessary to appear in public with the person we loved
most of all? Imagine this a prerequisite for social
discourse on Earth. It would change everything. She imagined
a phalanx of members of one sex surrounding a solitary
member of the other. Or chains of people. Circles. The
letters "H" or "Q." Lazy figure-8s. You could monitor deep
affections at a glance, just by looking at the geometry-a
kind of general relativity applied to social psychology. The
practical difficulties of such an arrangement would be
considerable, but no one would be able to lie about love.
The Caretakers were in a polite but determined
hurry. There was not much time to talk. The entrance to the
air-lock of the dodecahedron was now visible, roughly where
it had been when they first arrived. By symmetry, or perhaps
because of some interdimensional conservation law, the
Magritte doorway had vanished. They introduced everyone. She
felt silly, in more ways than one, explaining in English to
the Emperor Qin who her father was. But Xi dutiftilly
translated, and they all solemnly shook hands as if this
were their first encounter, perhaps at a suburban barbecue.
Eda's wife was a considerable beauty, and Surindar Ghosh was
giving her a more than casual inspection. Devi did not seem
to mind; perhaps she was merely gratified at the accuracy of
the imposture.
"Where did you go when you stepped through the
doorway?" Ellie softly asked her. "Four-sixteen Maidenhall
Way," she answered. Ellie looked at her blankly. "London,
1973. With Surindar." She nodded her head in his direction.
"Before he died." Ellie wondered what she would have found
had she crossed that threshold on the beach. Wisconsin in
the late `50s, probably. She hadn't shown up on schedule, so
he had come to find her. He had done that in Wisconsin more
than once.
Eda had also been told about a message deep inside a
transcendental number, but in his story it was not p or e,
the base of natural logarithms, but a class of numbers she
had never heard of. With an infinity of transcendental
numbers, they would never know for sure which number to
examine back on Earth.
"I hungered to stay and work on it," he told Ellie
softly, "and I sensed they needed help-some way of thinking
about the decipherment that hadn't occurred to them. But I
think it's something very personal for them. They don't want
to share it with others. And realistically, I suppose we
just aren't smart enough to give them a hand."
They hadn't decrypted the message in p? The
Station-masters, the Caretakers, the designers of new
galaxies hadn't figured out a message that had been sitting
under their thumbs for a galactic rotation or two? Was the
message that difficult, or were they .. . ? "Time to go
home," her father said gently. It was wrenching. She didn't
want to go. She tried staring at the palm frond. She tried
asking more questions.
"How do you mean `go home'? You mean we're going to
emerge somewhere in the solar system? How will we get down
to Earth?"
"You'll see," he answered. "It'll be interesting."
He put his arm around her waist, guiding her toward the open
airlock door.
It was like bedtime. You could be cute, you could
ask bright questions, and maybe they'd let you stay up a
little later. It used to work, at least a little.
"The Earth is linked up now, right? Both ways. If we
can go home, you can come down to us in a jiffy. You know,
that makes me awfully nervous. Why don't yon just sever the
link? We'll take it from here."
"Sorry, Presh," he replied, as if she had already
shamelessly prolonged her eight o'clock bedtime. Was he
sorry about bedtime, or about being unready to denozzle the
tunnel? "For a while at least, it'll be open only to inbound
traffic," he said. "But we don't expect to use it."
She liked the isolation of the Earth from Vega. She
preferred a fifty-two-year-long leeway between unacceptable
behavior on Earth and the arrival of a punitive expedition.
The black hole link was uncomfortable. They could arrive
almost instantaneously, perhaps only in Hokkaido, perhaps
anywhere on Earth. It was a transition to what Hadden had
called microintervention. No matter what assurances they
gave, they would watch us more closely now. No more dropping
in for a casual look-see every few million years.
She explored her discomfort further. How. . .
theological . . . the circumstances had become. Here were
beings who live in the sky, beings enormously knowledgeable
and pow-erful, beings concerned for our survival, beings
with a set of expectations about how we should behave. They
disclaim such a role, but they could clearly visit reward
and punishment, life and death, on the puny inhabitants of
Earth. Now how is this different, she asked herself, from
the old-time religion? The answer occurred to her instantly:
It was a matter of evidence. In her videotapes, in the data
the others had acquired, there would be hard evidence of the
existence of the Station, of what went on here, of the
blackhole transit system. There would be five independent,
mutually corroborative stories supported by compelling
physical evidence. This one was fact, not hearsay and
hocus-pocus.
She turned toward him and dropped the frond.
Wordlessly, he stooped and returned it to her.
"You've been very generous in answering all my
questions. Can I answer any for you?"
"Thanks. You answered all our questions last night."
"That's it? No commandments? No instructions for the
provincials?"
"It doesn't work that way, Presh. You're grown up
now. You're on your own." He tilted his head, gave her that
grin, and she flew into his arms, her eyes again filling
with tears. It was a long embrace. Eventually, she felt him
gently disengage her arms. It was time to go to bed. She
imagined holding up her index finger and asking for still
one more minute. But she did not want to disappoint him.
"Bye, Presh," he said. "Give your mother my love." `Take
care," she replied in a small voice. She took one last look
at the seashore at the center of the Galaxy. A pair of
seabirds, petrels perhaps, were suspended on some rising
column of air. They remained aloft with hardly a beat of
their wings. Just at the entrance to the airlock, she turned
and called to him.
"What does your Message say? The one in pi?"
"We don't know," he replied a little sadly, taking a
few steps toward her. "Maybe it's a kind of statistical
accident. We're still working on it." The breeze stirred up,
tousling her hair once again. "Well, give us a call when you
figure it out," she said.
