Generation Ships

Generation Ships


Historian Arnold Toynbee once said Civilization
is a movement, and not a condition, a voyage and not a harbor. When it comes to civilizations on century
long interstellar voyages, this is very true indeed. So today we will be beginning our look at
generation ships and how they might help us colonize the galaxy. We have four episodes planned for that over
the next few months and today we will begin with the basics, including examining why you
would use this approach and reviewing what the other options are. The origin of the Generation Ship concept
comes from an essay published 90 years ago by J.D. Bernal, also known for the Bernal
Sphere, one of the space habitats we discuss here a lot though not as much as the O’Neill
Cylinder. At the time of its writing, science fiction
was really just beginning to bloom as a genre. Of the Big Three: Isaac Asimov, Robert Heinlein,
and Arthur C. Clarke, none of them would publish a story for over a decade yet. Asimov and Heinlein very rightly were in our
first year of SFIA Books of the Month, sponsored by Audible, and as we close out that first
year with our twelfth winner, it is very appropriate that be Arthur C. Clarke’s 1973 novel, Rendezvous
with Rama, which tells the tale of mankind’s encounter with an alien Generation Ship. You can pick up a free copy of “Rendezvous
with Rama” and also get a 30-day trial of Audible, just use my link, Audible.com/Isaac
or text Isaac to 500-500. Generation ships, also known as Interstellar
Arks, work on the principle that the stars are so far apart that you could never reach
them in a single lifetime, and back in 1929 when Bernal wrote his essay, we did not have
any spaceflight, and only very simple rockets and equations for them. That essay, “The World, the Flesh & the
Devil”, which I’ll link below, is ironically one I’d never read till around a year ago,
but channel regulars will notice a lot of familiar concepts in their earlier stages
there, complete with discussion of sailing into deep space using solar sails. In the absence of powerful lasers or atomic
rockets, any such ship, destined for even the nearest stars, would take a near eternity
to arrive. A ship moving at just 1% of 1% of light speed
would take 40,000 years to reach the nearest star and that’s the kind of speeds modern
spacecraft tend to achieve and what the rocket equation, already known in Bernal’s era,
would suggest as a maximum limit at the time. Right from the start we knew about the major
problems. Such a ship was in no way possible at that
time, 3 years before we discovered the neutron and began considering atomic energy as a power
source, there was simply no way such a ship could survive the journey with an intact biosphere. No chemical fuel could keep plants lit and
habitats warm for those immense journeys. To add to that, you need a very large ship
to maintain any diverse ecology for future colonization and to support enough people
that they didn’t all start growing third arms from inbreeding. Many solutions were proposed for this, some
effectively abandoning the generation ship notion entirely, but this is when the seed
was planted. That of course was the purpose, to colonize
and seed other planets. As to the why, I think most folks know the
obvious ones already, they range from not wanting all of humanity’s eggs in one basket
to just an extension of our desire to wander and explore, the pioneering spirit. These all sound good, but there’s a big
difference between traveling around the galaxy at warp speed and voluntarily getting on a
ship that will be the final resting place for you and your next dozen or more generations
of descendants. These are trips lasting so long that even
if you are the hundredth such ship to launch you still won’t have heard back from the
first one yet to know if they succeeded or died horribly. So, while it gave us a potential pathway to
the stars, it didn’t seem likely anyone would choose to follow it. Indeed, this was the obvious solution to the
Fermi Paradox back when Enrico Fermi first suggested it, and he didn’t regard it as
a paradox at the time. Such ships simply were not realistic at that
time, Fermi died in 1954, quite some time still before we even went to orbit, let alone
our own moon. So while a species might colonize its own
solar system, the idea of getting to others seemed like something limited to science fiction. Yet it got discussed a lot in science fiction
and with many serious and science-based solutions to the various problems. Many of those, again, didn’t involve generation
ships at all. We discussed the five major types of interstellar
colonization vessels way back at the end of season 1, and added a sixth variation the
following year. In order, those were Methuselah Ships, Sleeper
Ships, Generation Ships, Seed Ships, and Gardener Ships. We’ll be adding some variations to those
as we move through this series and talking about when or if each of these options, or
a combination, will be most effective. We will also be asking ourselves, next episode,
if a lone ship is really a good idea, or if you should be employing a fleet, and if so,
should that be a fleet moving together or strung out in a long line, with a vanguard
arriving first followed by waves of vessels. But on a long voyage through deep space, with
new generations being born, you no longer have volunteers and many skill sets might
be lost. Initially that was a bigger concern. Remember, Bernal’s essay predates any electronic
computers. Even once we had them, for most of the 90
years since Bernal’s essay, computer hard drives were little better than books at data
storage, either in terms of data density or ability to resist damage. So it was thought that generation ships would
have had to carry real books. But even with modern data storage allowing
us to carry the sum of all human knowledge in one’s pocket, skills with no purpose
can get forgotten and are hard to relearn just from records. There’s not much call for a geologist on a
space ark after all. Yet with each new advance in technology, new
approaches to making generation ships viable or offering an alternative have arisen. So let’s review those basic designs and
how they vary from a Generation Ship and why. Each has its strengths and weaknesses and
seeks to address some problem of the basic generation ship or exploit some new technology
that’s been discovered or proposed since the original concept. The first, the Methuselah ship, approaches
it from the standpoint of having life-extension technology. It doesn’t get around the long time the
crew must endure, but it does get around the problem of generations. The people who get on board such a ship can
be assumed to be volunteers, and ones with a clear idea what they need to do, and the
skills and technology for it. Methuselah ships get around the problem of
the crew being unwilling, after the first generation, or unskilled, because the first
generation is still around, indeed there may not be any future generations until they arrive. With limited resources on a small ship, breeding
more folks on the flight is maybe not a good idea, but if you did, those additional folks
or replacements would still have living ancestors who raised them and know what needs doing,
all the way till the final destination. Additionally, a Methuselah Ship implies a
level of medical or nanotechnology that can help deal with concerns about long term space
voyages, both the hazards of space travel and the genetic and ecological issues. Such folks are presumably either genetic wizards
or masters of cybernetics and nanotech after all. Our next type was the Sleeper Ship, which
is poorly named in some respects, since you are dead not asleep, so tomb ship might be
more apt, but Sleeper Ship still conveys the intent. Everybody gets frozen, unless you’ve got
some magical stasis technology, and thawed out on arrival. Or almost everybody does, a ship needing a
crew or maintenance in flight might keep to a generation ship approach for a small crew
with a vast number of frozen colonists. Alternatively they might wake pilots and maintenance
personnel for a few years each, either waking the whole team for a few weeks to assess the
current state of the mission and do some repairs, then freezing them again for a few years before
waking them again, or keep shifts, where a thousand year journey might have a hundred
crew teams, each thawed out for a decade before going back to sleep. Animals and plants for terraforming are kept
on ice the whole mission. In this way, the Sleeper Ship avoids both
unwilling passengers born during the flight, and loss of skills in future generations. This seems ideal but for two problems. First and most obviously, it has been over
half a century since the first person was cryo-preserved, and we still lack the technology
to thaw out and re-animate humans. Incidentally the first was Professor James
Bedford in 1967, not Walt Disney who was never frozen, but was cremated, and nobody’s really
sure how that rumor started. As I mentioned back in Interstellar Colonization,
the technology to resurrect people long frozen is probably the same as to keep them alive
without aging, since it requires massive cell repair, so if you can do a sleeper ship, you
can do a Methuselah Ship. This does not mean you wouldn’t do a sleeper
ship though, as keeping a ship and its passengers alive for the whole trip is demanding in resources
and energy, whereas keeping people frozen in interstellar space is rather easy, and
such a trip is also presumably fairly boring too. However, the second problem with cryo is that
things which are frozen are not in a magic bubble in which time does not pass. Even ignoring the damage done while freezing,
decay still happens. What’s more, no matter how cold you make
someone, it will have no effect on atomic decay. Many of the substances in our bodies are radioactive,
particularly Potassium-40, hence the overblown concerns about banana radiation. I’ve seen some varying figures for the total
doses of radiation we get just from our bodies, not external background radiation, but I’ll
go with the 0.3 milliSieverts per year from the Health Physics Society, and its only about
a tenth of the total most of us get from background radiation overall. You’d need about 10,000 times that to get
a lethal dose. However, if you’re frozen, isotope decay
is still occurring, and without the usual repair mechanisms to keep things in check. Using the HPS data, if you freeze someone
for 10,000 years they’d get a lethal dose. Just from the various radioactive materials
in our own bodies. So there are limits as to how long you can
keep people frozen, unless you are reviving them periodically to fix that damage, assuming
you even can. Indeed, space is not exactly known for its
lack of radiation either, so your timeline is a lot shorter unless you are very well-shielded. To keep people frozen longer, you either need
to be able to repair them with nanotechnology while frozen, which might be rather difficult
considering nanotech isn’t immune to the cold either, or again you have to wake them
up and let repairs occur. Which is okay if you are cycling personnel
to run and repair the ship, just waking folks every few centuries to do a couple years of
work and heal up before being frozen again. No indefinite frozen voyages though, freeze
folks for a few millions years of travel to another galaxy and they’ll all wake up thoroughly
dead. Our third type, the classic generation ship,
we’ll skip for now. Type 4, the Seed Ship, essentially is a robot
that arrives in a system and terraforms a planet. It can be used as a speedy vanguard to ships
with colonists arriving later or in more high-tech forms, and could potentially grow everything
and everyone there. Depending on your technology or inclination,
it might simply prepare the location for more thorough terraforming, or just growing plants
and insects, or even animals, or people it raises and teaches. Having a vanguard is an example of why you
might use a fleet, arriving in bits and pieces, and it is likely that even single colony ships
would at least send fast probes ahead to do detailed flybys of various planets and to
confirm the target is ideal for colonization or look at some neighboring ones the ship
could divert to if it wasn’t or as emergency alternatives. However a seed ship could potentially grow
people without minds, be that cloned but mindless bodies or androids, into which colonists’
minds could be uploaded. And this brings us to our fifth one, the Data
Ship, which is essentially abandoning biology entirely in favor of simply bringing self-replicating
machines and data, including digital copies of minds. These two types, Seed Ships and Data Ships,
have merged a bit as concepts as technology improved, because a Seed Ship planning to
grow people or build androids is essentially a data ship, and more to the point, information
can be sent at light speed, so neither needs to carry much data. A tight-beam, high bandwidth laser can be
shot at the destination to coincide with when the ship is expected to have arrived and gotten
the basic colony apparatus in place. Thus getting around some of the concerns with
data storage for very long flights or everything being very out of date when it gets there. Moreover, DNA can be stored digitally and
printed, so a Seed Ship need not carry frozen genetic samples along on its voyage. Of course, these are very tiny and fast approaches,
and cheap too. As we’ll see as we explore generation ships,
these are huge vessels, whereas a data ship or seed ship is much smaller. Indeed, a data ship potentially might be as
small as a model ship someone would keep on their shelf or mantle. Data can be stored very densely, even when
you are including many redundant copies to deal with data decay or damage, and again,
a tight beam aimed to arrive from home about when the ship would be in place can get rid
of any non-essential data that isn’t needed for the trip or initial setup. Either version might begin not by terraforming
a planet but by building a giant receiver dish and data storage banks instead. Indeed, the data ship may be more akin to
a Von Neumann probe, only instead of building a copy of itself, it builds the needed infrastructure
and then builds the colony. It’s tempting to think the ship’s planetary
probes can go faster because they’re smaller, but that’s flawed reasoning. The energy required to achieve a certain speed
scales linearly to mass, so a bigger ship with a proportionally bigger engine and fuel
tank can get going just as fast. The real reason your probes can travel ahead
faster is because they don’t have to slow down, arrive safely, or return to you. While your colony ships need to use fuel to
slow down as they near their destination system, probes can use all their fuel accelerating,
do their job of gathering data to send back, and shoot through into space. Though they might save a little for a course
correction to check out alternate targets further ahead your ship could likewise detour
to, waste not, want not. They take way less total mass to build and
fuel of course, allowing you to build hundreds for every star in the galaxy out of a single
modest asteroid, but they rely on a level of smart automation to manufacture that makes
this redundant too. A gigaton space ark might weigh as much as
a trillion tiny data ships, but the Asteroid Belt, our topic for last week, masses about
3 billion Gigatons, enough for 3 billion such ships, and our smallest planet, Mercury, has
enough for 300 billion ships, enough for every star system in our galaxy. So mass is irrelevant in this context, and
if you’ve got tiny ships that can colonize whole solar systems, then you can just as
easily have them rip apart a few large asteroids or moons in our solar system to make a ton
of giant ships instead. You also have no need to send a ship to each
star, as the first wave can arrive at the nearest few hundred systems and build more
of any type, such as data or seed ship, it just builds copies of itself to go to other
systems further out before getting to work on terraforming a planet. Generation ships can do this too, but it’s
assumed to be a lot slower as they presumably need centuries if not millennia of settling
their first system before they’d have the time or desire to send out the next wave. Fundamentally Generation Ships are self-replicating
machines, just as humans are, its just that neither requires tons of technology we don’t
have yet, even on the drawing board. This is where our last ship type, the Gardener
Ship, comes in. In many ways it is just a normal Generation
Ship incorporating some of the other concepts. We discussed this in the Life in a Space Colony
series, but it’s basically on a long voyage with everyone awake, and with the ability
to manufacture goods en route, rather than bringing everything from home. Suddenly your generation ship is not a one-time
use vessel. There’s no reason that they can’t be breeding
up their numbers during the voyage, indeed we assumed life-extension technology was available
to it and so they’ve got a rising population if they have any kids at all, unlike a generation
ship which can simply limit breeding to replacement levels. They arrive at a system, leave some of their
people there while helping the colony get started, and fly off with a full fuel tank
and raw materials sourced from that star system. During the voyage they can turn those raw
materials into colonial equipment and the crew can breed new colonists. Since the ship needs to be able to repair
every component of the vessel, they can, much like the self-replicators of the data and
seed ship versions, actually even spawn new ships or sub-divide their ship into two ships
every so often, which will head off to separate destinations. With this, you can build rather huge generation
ships because you only need a few hundred to be built back here in the Solar System
to get the whole galaxy settled quite quickly. They won’t get it done quite as quick as
a self-replicating probe will, but they won’t be much slower either. They move at the same speed and mostly just
stop for longer, but on century long journeys between each stop, little difference is made
by them stopping for a few years compared to the probe stopping for a few hours, or
that the probe can probably decelerate and accelerate quicker. So those are the main alternatives to the
classic generation ship. However a lot depends on what we mean by classic
generation ship. The original versions tended to assume you
needed millennia just to get to the nearest solar system. We already have designs for ships using current
tech we can build right now, albeit for costs that would bankrupt nations, that could get
to our nearest neighbors in centuries or even decades. We’ll talk about those designs more next
time, but they change the dynamics a lot. How fast a ship can go, how long you can keep
people and equipment alive and functioning, and how quickly you can build en route or
at your destination all heavily influence how you colonize. For instance, with several of these designs
there’s no need or point to Earth sending more than a small handful of ships out, whereas
with classic generation ships you want to send them as far as you can because your own
colonies will be a long time growing before they send their own. And you can always get a ship from Earth to
a destination faster by sending it directly, rather than by having it zigzag a bit and
stopping to do stuff, refueling or replicating, and speeding back up again. We also have other advantages that let us
make colony ships smaller, and thus let you build more of them. For instance the big concern originally was
that such a ship needed to be big enough to support a genetically diverse ecosystem that
wouldn’t bottleneck either. For its human crew we tended to assume a need
for thousands of colonists to avoid that. However, in the first place, we could bring
along huge quantities of frozen fertilized embryos for implantation, we already have
that technology. In the second place, we will most likely have
the tech to fix genetic issues that crop up from breeding too closely long before we get
our first space ark built. This doesn’t mean you don’t need or want
a large ship with a large ecology on it, and we’ll discuss the challenges and solutions
of that more in the third episode in this series, Exporting Earth. Keep in mind, though, that even if you’re
bringing only two of every kind, elephants take up a lot of room. The picture we begin to see emerge though
is that a realistic generation ship is going to include facets of each of those other variations. It is going to carry large freezer banks,
even if you can’t revive frozen people. It is going to have self-replicating technology
on it, even if it’s in the more conventional sense of just having enough factory and industry
to make any given object from raw materials obtained on arrival. It is likely to employ a vanguard, even if
that’s just fast flyby probes to take readings of the system before you arrive or scout ahead
to help the ship avoid dangerous interstellar space junk. It is likely to have huge databanks containing
all our art and science and history, and for that matter, digital copies of DNA so they
can fall back on those if frozen supplies are damaged or can’t store long enough. It isn’t likely to make building a big receiver
dish its first project on arrival, but only because it will likely already have one so
it can be receiving data from home the whole time. News, technological breakthroughs, new TV
and books, and likely intermittent repeats of all essential knowledge in case something
vital is lost. Another thing we’ll explore more in the
fourth episode is that your colony effort is not just limited to the folks on the ship
even after it launches, someone has to keep sending them new info from back home for instance. That episode, the Million Year Ark, will focus
more on long terms changes of mission and culture on ships, where we’ll try to tackle
the challenge of keeping a generation ship intact and on-mission for a million years. Back home though, you’ve got the same problems. You want to make sure your ship isn’t reliant
on information from home but you want to have that option, so it makes sense to invest some
of your colony-ship building funds into creating a trust or foundation that will keep rounding
up data and sending it to you. That’s not an easy thing, considering how
few organizations survive for centuries and far fewer of those stay on their original
mission. Just as an example, a trust set up in the
1500s to ensure funding for colonizing the Americas would probably have had a department
dedicated to the shipment home of plundered goods and slaves, and the exporting of missionaries
and possibly soldiers to encourage those missionaries get listened to. I think we can assume, if they had existed
then, sometime in the last century or two there’d have been some major overhauls to
that foundation. You want that support from home, and you want
to pack all the gear you need, not raw materials, but fundamentally you need such a ship to
be as self-contained as possible, able to survive without info from home and build what
it needs for the journey. Moreover, you need to make sure it can recycle
everything very efficiently and doesn’t leak. This is a problem, because everything does
leak. You take hydrogen for instance, the preferred
propellant for ships and fuel too if you’ve got fusion. Its fine for getting up to speed but hydrogen
is so tiny it tends to escape through materials, much as a chicken wire mesh can keep in a
chicken but not an ant. Think of your party balloons and how they
lose their buoyancy over just a few hours. This is a bit of problem if all your supplies
of fuel to slow down evaporate out of the ship before you arrive. And we’ve got the same issue with things
like air and water reserves. Bigger, thicker ships and new and better materials
can help with these problems, as can innovations in improved recycling efficiency, but are
unlikely to eliminate them entirely. One of the solutions for this, without giving
too many spoilers for our book of the month, Rendezvous with Rama, is to essentially use
a sleeper ship on a bit of a grand scale. You send out a giant ship that can support
a whole ecology, but keep it all frozen or in hibernation. The book may be 45 years old at this point,
but still discusses a lot of the issues with Generation Ships and space colonization in
general, and like most of Clarke’s work, it’s very hard science fiction. Since it is on the older side and we will
be focusing in this series on methods suggested with newer technology, you can read that to
get a fair idea of a lot of the problems envisioned for generation ships that we’ll be addressing
in the rest of this series. As books go, it’s a classic, and it features
one of the classic tropes of science fiction. A giant object is spotted entering the system,
identified as not being natural, and the brave explorers set off to explore it and unlock
its mysteries. Clarke writes them well, as the expedition
members act like skilled adults not blundering around stupidly making crazy decisions. That object, Rama, is a giant cylinder 20
kilometers wide and 54 long, a good deal bigger than the behemoth O’Neill Cylinders we discussed
recently, and far larger than the ships usually envisioned for space travel, and is spotted
entering the solar system at over 100,000 kilometers per hour, which while fast is still
only 1% of 1% of light speed, meaning that a journey to even the nearest star would take
it many tens of thousands of years. While we will contemplate journeys of that
duration and even longer in this series, we will be trying to show how you can do them
far faster with more advanced technology. Clarke shows us how it might be done with
the technology they had back when he wrote it, or at least technology comfortably on
the horizon. It’s a great book and considered one of
the best by one of sci-fi’s legendary authors, and you can get a free copy today of Rendezvous
with Rama, just use my link in this episode’s description, Audible.com/Isaac or text Isaac

you stay on with Audible or not. Also, for a limited time, Amazon Prime members
can get the first three months of Audible for the price of one, and you can enjoy all
your fun outdoor summer activities while listening to your favorite books. All right, as mentioned our next episode in
the series will focus more on the mechanics of such ships and factors like flight time
and propulsion, fleets of colony ships versus lone ships, and more, in Exodus Fleet. But before then, we will look at how a galaxy
settled by humanity might look after a while, when we join up again with John Michael Godier
next week for a two-part episode exploring what a colonized galaxy will look like. For alerts when those episodes come out, make

    Ah damnit it actually just hit me – generation ships = Noah's ark ~=That dude, Jonah (?) who lived in a whale – of course will be interpreted (if not already) as prophecies of the bible by one or more of the cults. "Don't be silly no one actually thought someone lived in a whale – it was a metaphor for spaceship". Ah damnit that's most probably why the Mormons were the ones building the generation ship (have not read the series:). Well, if it finally hit me, it's not far from the lowest common denominator – brace yourself, the new wave of woo is coming 🙂

    Is there enough mass in all the asteroids in the asteroid belt to create a new planet? If you could somehow conglomerate them together, would a planetary core form, similar to Earth's? Is the planetary core just a matter of substance plus pressure, or is there more going on there? If we could make a rocky planetoid with magnetoshpere, could it then hold water introduced via comets etc? Have followed this channel for sometime, love it. Thank you for your work

    I'm a fan of generation ships capable of asteroid mining and space dust collection. I don't know the composition of small space debris and dust but I assume it would include a bit of everything in one form or another, which should hopefully mitigate any small losses over time.

    I take issue with your "dead not asleep" comment. I agree "sleep" is the wrong word, in the same way that people in most types of comas are not sleeping, but dead is no more technically accurate. Many accepted definitions of death over the years have included the word "permanent", or a synonym, and when talking about the flatworms that can be dehydrated and rehydrated we do not refer to them as dead when in the dehydrated state.

    So a future society is thought to solve the problem of antimatter or fusion starship engines but can't figure out how to turn off human aging? Seriously? I will say that in the 1960s, before human genetics were known, before we knew aging was almost certainly something that can be hacked, it might have seemed reasonable that aging would be a harder problem to solve than starship engines.

    The first ship to depart would never be the first to arrive. Advances in technology would ensure you would be overtaken within a lifetime or so.

    How would they get the raw materials to manufacture the new tech when it arrives while still travelling to said destination you can only bring a limited amount with you and theres also a limited amount of recycling you can do. I get melting down any old, obsolete or broken tech to recycle and re-use. And I know absolute efficiency is practically a prerequisite of any spaceflight but your still going to get to a point where you simply can't recycle the metals because theres nothing to do so with. And you'll quickly run out of stored raw material. Your still in flight at relativistic speed so how do you get more materials?

    It is always fun to find such ships in Elite Dangerous.
    Imagine that if you going with 10% of the speed of light and sending small probes with nuclear warheads to destroy potentional asteroids. Then a passive not much an explorer aliens finds that offensive…..

    I would bet that most of the crossings between stars will be done by "dwellers between stars" who don't even really care what star they're closest to. Maybe the new habitat they've just founded is technically in orbit around some star or other, or maybe not; they don't really care as long as it takes them places where there are useful resources: rogue planets, ejected objects, plutinos, oort cloud objects, brown dwarfs …. there is a hell of a lot of real estate out there when you quit caring about being close to stars.

    You know, at this point in our technological development, we as a civilization should nail down some of these concepts when discussing artificial lifeforms. Just like we did with finally defining what a "planet" was, we should do so for "robots" and "androids".
    Robots are mechanical objects that do multiple specific tasks on their own. A wheel, lever or pulley is NOT a robot, but a machine none-the-less. Actual robots should range from vehicle manufacturing robots to planetary rovers, to roombas.
    Androids should be defined as mechanical objects that not only mimic functions that humans do, but also mimic specific features including, by and large, the shape of a human, at least in that they should have a head (primary sensor, possible control) appendage, arm appendages (for work/fine tasks) and leg (mobility) appendages. For this definition, I wouldn't accept a humanoid robot with head, 2 plus arms and wheels or tracks though. The 5 main appendage and plan would have to be in effect.
    Now, something like a Replicant, a BIO-mechanical object that mimics functions, shape and functions but using primarily organic materials arranged in organs or humanoid structures and is even more lifelike should be a separate definition. This should be an entity that is not fabricated whole cloth, that is, fertilized, incubated and matured over a human lifetime time scale. That would be a Clone IMHO. No a replicant would be, just as in "Blade Runner" a bio-mechanical entity, stitched together using specifically grown parts and being, other than upon very close, microscopic or genetic inspection, identical to a human. Frankenstein's monster would not fit this description as it used reanimated dead parts stitched together.
    So how this systematic classification would work as I see it would be:
    USS Enterprise, Millenium Falcon = machine
    Nightrider's KITT, Elon Musk's driverless cars or self driving APC's, Terminator T1 Hunter Killers or Arial Hunter Killers = robots
    Star Wars's Wed Tredwell, Power droid and R2D2 = robots
    Star Trek's Data, Terminator endoskeletons, C3PO, Asimov's Daneel Olivaw, I Robot's NS-4's or NS-5's = Androids
    Philip K Dick's Roy Batty = Replicant
    Mary Shelley's Frankenstein's monster = ?

    SPOILER ALERT: Rama technically did NOT freeze any beings. All biobots were reclaimed in the Sea, and then Sea with all components were frozen. Then new ones were created from scratch. Basically, the only trick in hard-sf part was avoiding storage deterioration (though we already have ones esitmated to last billions of years!) and vaccum welding. And btw: entire Rama cycle is 1+3 and kind of… well…. reminding three, are.. different.

    Just a small correction. The speeds you listed for Rama are not entirely correct. It was slowing down as it was approaching the sun and it is stipulated in the book that it took the approach of accelerating rapidly up to speed and then coasting or decelerating at the halfway mark before entering a new system. It might also be worth mentioning that while the book never revealed the exact nature of the drive system it was capable of either manipulating it's gravitational field in relation to the sun or producing one of it's own seemingly without mechanical parts. Hence in contrast to a typical generation ship as discussed by human beings it's clear that the Ramans have technology and an understanding of the universe we still lack as the means by which gravitational force is conveyed still eludes us although the effect is very well understood. Full disclosure i have just read the first book so some of this may have been clarified in the second and third book although I have heard from some people that if you liked the exploration element and mystique of the Ramans from the first book one might want to shy away from the sequals.

    The planet Earth is the ultimate generation ship…traveling through space, with everything we need…endless power (for now), courtesy of the Sun…all types of protection in place…from Jupiter attracting all the random crap thrown into the solar system…to the protection around Earth from radiation, etc.

    The only activity that would keep people going is discovery. Take that activity away, and your ship and your civilization are dead (after they are debauched, of course).

    If you can maintain human civilisation on space habitats and generation ships, then really, people born on those ships with their comfortable man-made environments would be in no hurry to colonise lifeless planets. They could still do it, but the majority would still be living, working, vacationing and night-clubbing in space habitats. Terraforming new planets may be done by private organisations and volunteers, while other corporate bodies will see planets as only good for providing raw materials for building better artificial planets and habitats. Who wouldn't turn Mercury inside out to build a new Earth-sized planet on which to sell real estate on?

    Some interstellar communities, however, will eschew star systems to live as nomads among the stars, never settling anywhere short of setting up laser-relay or stellaser installations to externally propel their spaceship-habitats for thousands of years. Space is full of rocky debris with which they can strip down for raw materials and either expand their own vessel or manufacture new ones for offshoot communities.

    Where do you purchase your marijuana and which hydroponics process or flavor do you prefer?
    I don't think humans since the industrial revolution would be capable of any of the most basic achievements beyond the one defunct Space Shuttle programs.
    They over generations have been inbreed by class, race, economic, education and materialism competition to do no more than fight, kill and debate their position over the success of the whole.
    Ants, bees, and other insects would make better candidate for million-years space travel, because they are genetically breeded without question to instinctly follow a chemical-based lifespan with precision…even at the risk of death.
    Great animations though…maybe we should recolonalize Earth by restoration, defense and innovation upgrades that will build the human capacity to "naturally" move to the moon, then further out as our capacity to think differently as a whole.
    Maybe uploaded consciousnesses into robotic or Android ship operators would be even better just for mineing operations and asteroid defence projects would in the immediate term be more long-term advantageous…the spin-offs would be equal to that of the other big-dollar space programs and more importantly humanity may learn how to clean it's room before trying to move to another clean room only to trash it too.

    Arthur, why are you such a skeptic about suspended animation but a fan of freezing people. You dismiss thoughts about hibernation with the vague remark that it is dangerous for chipmunks and such. Really? We can do no better? There has not been much work on this technology because there has been no need for it, but it would seem a heck of a lot easier to put someone into cold sleep then repair the damage done by freezing. That is, if there is any point to rebuilding dead people. Even if it is possible, which I doubt, why go to all that trouble? Just make new ones.

    Alternatively, I suppose a sleeper ship could employ a crew of people who've undergone life extension, & have agreed to man the ship for the duration of the trip. Such people might be paid handsomely for their efforts – even more if they agree to stick around for a while once the destination is reached, & help the colony set up shop, then leave once the colony is safe & sustainable. They could even return in the same ship, & ferry others somewhere else. In this way, they could hitchhike across the galaxy! That's assuming hibernation could be perfected – a big if.

    So you got yourself clarketech, and it can be done well, but you know what i’ve never seen done adequately? A fantasy world with magic that exploits said magic to power it’s technologies? Would that be called magetech? Interesting creative thoughts abound there, most certainly. If wizards can generate fire by meditating without burning anything to produce emissions, would a mageworld have steam engines be their primary mode of locomotion? How many chain lightnings does it take to power a lightbulb? If you can levitate, and summon homonculi, why not sling that bugger into space?

    Do you have any video discussing the generation ships in japanise anime. One that comes into mind is netflix godzilla. There they explore what happens when you leave a scorched earth and returns after generations and time dilation. Earth has developed in a very strange way. I found that fascinating eventhough the movie was more fantasy than hard sci fi. In that movie they also explored what happens if a alien pathogen enters earth and how earths biosphere, human introduces nano tech lifeforms and alien compete for dominance. Another fascinating topic is that it's more economical to wait out life to regenerate in a tomb than send yourself to space in a scorched earth scenario.

    There's no reason to send grown humans on slow ships. Instead, send 1 billion (for genetic variety) frozen DNAs of unborn humans, varieties of animal DNA, and stored-on-chips compendium of all human knowledge on a fast ship. At arrival, the programmed robots build Mckendree Cylinders (Oneill-like colonies made of carbon-fibers built large enough to hold an entire continent) to reproduce an earth-like environment for the new generations of humans who will be enculturated just as if they had stayed in the Sol-system, while they terraform Goldilocks-zone Rocky Planets and mine their system. Send back/receive data, and send back to Sol-system a small percentage of produced materials (kind of like an interstellar Ponzi-scheme) as "payment" for the project, and then send forward another fleet of colony ships to new stars. Home systems (ie Sol-system) can reproduce the colonized systems in specialized Mckendree cylinders and VR/Holodecks as pseudo-colony facsimiles. Repeat the process with each new colony.

    There's something that bothers me about this whole thing. All of this relies on many, many people having children at above replacement rates. But everything we're seeing today shows that the more educated people become, the fewer children they have and the longer they wait to do it. Maybe I'm a dum-dum, but did Isaac ever talk about this when mentioning however many quadrillions of people we plan to have for all of this colony business?

    [ GREEK – ΕΛΛΗΝΙΚΆ ]
    Η θανατηφόρα ποιοτική ανθρώπινη επιλογή – Μια Παγκόσμια Κυβέρνηση – Η πορεία μας στο αστρικό διάστημα. Όλη η ανθρωπότητα θα επηρεαστεί από κάτι τρομερό. Η θανατηφόρα ποιοτική ανθρώπινη επιλογή. Η αλλαγή των κυβερνήσεων και η έκθεση και η κατανομή των χρηματοπιστωτικών ιδρυμάτων. Ο πλανήτης σύντομα θα απαλλαγεί από το παλαιό σύστημα και τον έλεγχο. "ad astra per aspera !" "στ' άστρα μεσ' από δυσκολίες" (Το μέλλον μας είναι τα αστέρια)

    Όταν έχεις εξαλείψει το αδύνατο, αυτό που μένει, όσο απίθανο κι αν είναι, πρέπει να είναι η αλήθεια.

    We need 30000 rockets to create a civilization in mars but nobody can pay it… Also re usable rockets that get water out of this world to mars for refining the salty parts of the sea… That way no more floods probably…
