My classroom is Assembly Hall 3, two decks above my mess
hall. The first class is seventh tier –
most of them are twelve or thirteen years old, but a couple of them are a ten
or eleven, and a couple are fourteen or fifteen. Sometimes students are held back moving to
the next tier because of emotional maturity, sometimes because of intellectual
deficiency. I read accounts of teachers
on Earth long ago, and I marvel that such an inefficient and clumsy system was
ever acceptable – students advancing up the grades purely because of age.
I enter the hall; the students rise as I enter, and I motion
to them to sit. “Good morning!” I wave my hand in front of the podium, and
the display projects in front of me. “Enrolled:
44. Present: 43. Excused absences: 1.” I sweep my hand down and close it, and the
display clears.
Around the classroom, students are showing differing levels
of attention – as is usually the case at 0730.
“Janos, late night gaming?”
Janos’ eyes were closed, trying to catch a bit more rest, but he was not
asleep. He glares at me, but he knows
better than to talk back.
“Today we start with a part of history that I know interests
many of you, because it is why you exist.
Today we move away from ancient events on a planet that we will never
see and we explore our place, our meaning, our purpose.” I waved my hand again, and an ancient, low
resolution video appears above the podium, and above their desks. It shows our ship as it neared completion
almost a thousand years ago, a huge, uninspiring silver cylinder with only a
few markings indicating entry points.
Behind it, as the video panned to the left, was the curiously beautiful
blue and white orb of Earth.
I could hear a few sudden inhalations from my students as
Earth came into view, even though it isn’t new to any of them. I confess; no matter how often I see an image
of Earth, it makes me pause for a moment.
And it isn’t just Earth. When I
was their age, we passed a solar system with a planet that looked much like it,
and caused much the same reaction. We
almost spread our seed there, but at the last minute the biologists found
something incompatible with the life already there. Nonetheless, it was gloriously beautiful with
clouds and oceans and great cyclonic storms.
“Here is the start of our journey, a voyage of discovery and
expansion.” I scrolled my hand sideways,
and a galactic map showed our ship’s movement across the stars in one of the
spiral arms. I pulled my arm back
slightly, and the podium zoomed out from the map. “Our ancestors committed themselves and us to
a bold experiment, to seek out new homes for mankind, and to find other
intelligent life.” No surprises here;
the students pretty much all know how the story starts, but every story needs a
flourish of an introduction.
“Over the last thousand years we have traveled an enormous
distance through the galaxy.” I slowly
spread my thumb and index finger apart, and the slightly jagged line showing
our path across the galaxy completed. “How fast are we traveling?” I knew who was
going to answer the question; Janos was going to be a physicist in a few years,
and was already taking twelfth tier physics.
Jan raised his hand, and I nodded in his direction. “At full
cruising speed: .95c.”
“So how much time has elapsed on Earth since our journey
started?”
“At least 5000 years. We don't keep that full speed
throughout our voyage; when we slow down to visit a solar system, it reduces
our average speed. Time dilation is dependent on v2 divided by c2.
We know that a lot has changed on Earth since we left.” Jan frowned, but knew
better than to say more. The end of broadcasts was hardly a secret; still, it is
considered impolite to say it, rather like speaking ill of someone who has air
locked.
“So what happens when we slow down to visit a solar system?”
I looked around the classroom again, trying to find one of the quiet kids who
never volunteers. “Jana,” and stared at a pretty brunette trying to hide in the
last row of tables. “I know you're taking tenth tier biology already. I'm sure
you know the answer.”
Jana is very shy, and the look on her face screamed, “Why
me?” She looked down at the table and, just barely audibly, “We survey planets
that might contain intelligent life, or where our species might settle.” I
confess that I do not understand Jana’s shyness; she is very pretty, and in a
year or two, she will be very popular in Lounge C. Or perhaps someone did not
wait for her to come of age?
“What have we found so far?” I again stared at Jana. I'm sure that she feels very picked on by me,
but my job is not just teaching history to these kids, but also to socialize
them into a form useful to the needs of the ship. Jana looked around the classroom, with that
desperate look of, “Won't someone pick up the ball here, please?” It's always
hard to tell if her classmates were enjoying seeing her on the spot or simply
felt that she was most likely to give a correct answer. This is such a
ferocious age.
Jana realized that no one was going to save her from
answering the question. There is no room in our society for a person who is not
prepared to take the lead. And that is another reason why my job is to pick on
students like Jana. “So far, I think
we have visited 45 Earth-like planets, and found intelligent life on none. A few had life, but primitive."
“That is correct. No intelligent life. Even the planets with
life were shockingly simple. Photosynthesis, a few sea dwelling creatures, and
one planet with land animals. It was not at all what we were supposed to
find." I smiled at Jana. “What about planets habitable by man?”
In the front row Mark raised his hand. Mark was not shy; he
was a tall, muscular kid with curly blond hair and an infectious smile.
“Several so far. Some require terraforming because there's no life there to
produce oxygen, but by the time some other ship passes through, the plants
we've left will make those planets habitable. They'll be their own Edens.”
“Mark, you should probably explain what an Eden is.”
Mark turned around in his chair to make sure that everyone
could hear them; my guess is that he will end up as a teacher himself someday. There
certainly is not much need for any other form of public speaker in our society.
“I've been reading up on the ancient superstitions of Earth, and Eden is the
name of a perfect garden claimed as the origin of man.”
Before anyone had a chance to ask about those ancient
superstitions, I thought it best to keep the class headed down the narrative
that I had planned. “What about the planets that already have oxygen?”
Mark smiled even more broadly. “We seed those planets with
Earth plants and animals and pioneers. I want to be one of those pioneers!”
There was a brief tittering from some of the girls; there's something romantic
about being a planet pioneer, and even if Mark was not sincere in his desires,
I can see why more than a few teenaged boys have affected the planet pioneer career
path as a dating strategy.
“How many of you want to be pioneers?" I smiled as I
said it, so that no one would feel ashamed to say yes. There is a need for
pioneers, but someone needs to keep this ship headed outward. Our policy is to
neither encourage pioneers, nor to discourage them. Well, maybe discourage them
a little bit.
Perhaps five hands went up, some rather tentatively. “Why
would you want to be a pioneer?” I
continued smiling; I don’t want to discourage my students from expressing
interest in an almost disreputable
career goal.
“There's something unnatural about the way we live on the
ship.” For once, Jana spoke clearly and forcefully, without a hint of
discomfort. “I want to live on a planet, like my ancestors did. Not in a metal
box.” And to my surprise, not only Mark, several other students cheered and
applauded.
Melissa spoke next. “I want to grow my own food. I want to
sleep under a blue sky. I want natural children, my own children.” Now, instead of cheering and applause, I heard
gasps. This was not the first time that I heard a student express this desire,
and certainly among adults I have heard this strange request, but at this age
it is all quite daring to talk so directly about such things. “I want children,
not the black tube.”
It was time to redirect this conversation before became any
more awkward than it already was. “Well, some of you may get your opportunity. Most
of you know we are decelerating into a system with a very Earth-like planet.” I saw a couple of slightly surprised faces
but most of the students seemed to know this already.
The time had come to suggest assignments. “For this week's
assignment, you are to pick out some aspect of the launching of the expedition,
or of the history of the expedition to the present. I know some of you much
prefer the ancient history, but let's keep the assignment no more than 50 years
before launch. I expect you to make use of the usual sources, but if you are
researching something of recent history, feel free to conduct interviews with
people who were part of those events.”
One of the more satisfying parts of teaching in the modern
times was how many students did oral histories with people whose stories had
never been recorded. A few years back, one of my students had recorded the
experiences of the planetary exploration team that had explored SN 9468 – 4, an
Earth-like planet around a G0 star. This was 70 years ago, ship time, but the
memories of the disappointment were still very strong. A small team of pioneers
were already starting to build temporary structures on the surface, when the
cattle started to sicken and die. There was something in the indigenous
bacteria that was in conflict with our life forms; had they remained in contact
with the local biosphere, the pioneers would've died too. Of course, there were
technical reports of what had happened, but the intervening decades had granted
some perspective to the team that could not be found in the official reports of
that time.
Mark raised his hand. “I think I would like to explore what
the first members of the ship's crew thought would happen to their children.
Did they ask if we wanted to be born, live, and recycle so far from Earth?”
“Mark, just keep it dispassionate. Stick to the facts you
can find, and don't let your personal feelings take over the paper.” I knew
that Mark felt, as did more than a few of our society, being stuck on this
expedition by our ancestors was supreme selfishness. There was no way “home”
from here, even if everyone aboard agreed to turn the ship around. At least ten
generations separated us from the green hills of Earth. Some were embittered by
this knowledge; some leaped at the first chance to get something at least close
to “home” by becoming pioneers; some, in their depression, air locked. I could
understand their hurt and sense of loss, but
this was home, not Earth, nor any substitute, no matter how blue the sky,
how green the forests, or how luxuriant the grasses we planted there.
Fun story. How did they eliminate the liberal gene i wonder? And when will the aliens show up?
ReplyDeleteThe three meter tall sentient bipedal felines appear about chapter four.
ReplyDelete"Lounge C"? Sounds a bit threatening.
ReplyDeleteHowever - I know that the "generation ship" is a well established SF trope - but it's not really plausible.
A society which remains stable (fossilized, really) for over 1,000 years?
Norman Spinrad looked at this a while back, and concluded that a population which is adapted to living indefinitely in a particular situation is settled in that situation, not looking to settle somewhere else.
And think about being in such a situation - living among a few thousand people (at most) in a small habitat, in which nothing will ever change for many lifespans. There's nowhere new to go, no one new to meet. The only work to do is rote maintenance.
Harry Harrison had addressed the idea even sooner - his "generation ship" crew was deliberately intelligence-limited and wired into a stifling artificial culture.
A two- or maybe even three-generation ship could be plausible; but 20, 30 generations? This would be like ancient Romans expecting medieval feudatories to wear togas and revere eagles.
Not really fossilized as you will see but on the edge of ideological and spiritual revolution, like Rome.
ReplyDeleteIf I read correctly, this society is essentially the same as when it was created, a thousand years before. That's an extreme degree of cultural rigidity - far exceeding anything in known history.
ReplyDeleteIf it's now "on the edge of... revolution", why hasn't that happened long before?
Suppose you meet a man, and get to know him. Then you meet him again, 20 years later. He's wearing the same clothing, eating the same meals at the same time every day, working at the same job, living in the same house with exactly the same furniture in the same places.
Wouldn't you consider that man abnormal - obsessively and compulsively ritualistic?
Also, acceleration/deceleration to/from near light speed? Without some kind of "warp drive", the energy requirements are colossal. The ship's kinetic energy at .95 c would be equivalent to 44% of its mass converted to energy; where did that energy come from? And where would it come from the second, third, fourth time after the ship slows down to explore a solar system? Plus thrust for deceleration.
Power requirements even more than technology seems the biggest barrier to interstellar travel but imagine explaining jet travel to Ben Franklin.

ReplyDeleteYes, mopst societies change unless authoritarian or totalitariann methods are used: like N.Korea. Medieval Europe experienced relatively little social change for centuries. And yes, later chapters explore the changes, and how conformity is enforced.
