Intergalactic Travellers…

Humanity
colonize the moon in 2050. Both Mars and Venus are eventually
Terra-formed and colonies established by 2235.
.-...-.
When astrophysicists
and cosmologists learned that the sun would run out of fuel within two million
years we began, in earnest, to explore ways that would ensure humanities
survival.
We realized that
colonizing the galaxy was a pipe dream. Carboxy life forms like us
are not equipped to survive the speeds required to reach even the nearest stars.
We could not survive a journey that would last for centuries, and if it were
possible would we survive the boredom of deep space travel? We would
need to carry so much food, oxygen, water, and fuel for such a
trip. Just one interstellar ship would require all the resources of
planet Earth with no guarantee of success. Half our time would be
spent accelerating and decelerating in order not to overshoot the
target.
No! Humans are much too fragile for that, and too
short-lived. We are built to be stop-at-home bodies destined to
forever remain within our solar system until the sun runs out of fuel and ends
its life, and ours, in a fireball; taking the earth and all the planets with
it. If we have ambitions to expand beyond our solar system it will have
to be done by other means.
The best chance
of carrying fauna & flora from Earth to the stars would be in the modern
equivalent of Noah’s Ark,
as seeds, to be reborn at some far off destination, under the guidance of
machines. For our future, AI (Artificial Intelligence) would provide
the best chance of survival for Humanity and all living things on Earth.

In 2150,
our initial investment in the project was to send small ‘pathfinder’ drones
towards Proxima Centauri, Alpha Centauri A & B, Barnard's star, Luhman 16,
Wolf 359, and several dozen other neighbouring stars in our galaxy.
Given the right conditions, they would seed them with oxygenating plants, sending back word of their
success or failure. The earliest messages would take hundreds of
years to arrive back on Earth. By then the ships would be on their
way to their secondary targets.
In the intervening period,
humanity would be working hard to improve propulsion methods and increase the versatility of existing AI units.
Biologists would be
working to bring down gestation periods and improve methods of in-vitro
fertilization. Improving and miniaturizing artificial wombs. There
were no adverse effects when smaller creatures such as mice, cats, and dogs
were created, in the initial trials. Larger animals are the logical
next step to be accomplished by the end of the 23rd century.
The second tranche, of
small ships, would be sent to the prime planets, identified by the ‘pathfinders’
as having water and being situated within the Goldilocks zone of their star.
There were of course
protests & riots by religious and fringe organizations. So much
so, that for a while the plans were publicly put on hold; but, in private they continued apace. Intelligent
miniaturized devices were developed small enough to travel, yet large enough to
build and upscale to larger machines that could create a liveable Earth-type
environment. All the knowledge from the homeworld would be stored in
teaching units so that even in their artificial wombs children could be
schooled for their new environment. Thus humanity and other earth
life forms could be transplanted to other worlds.
.-...-.
The plan would be:
AI – would advance
into the Universe claiming resources to improve, modify, advance, and justify
their own existence.
Each Ark, containing the
seeds from its creator’s world would be sent with the latest technology
currently available to them.
These small sub-light
crafts would carry with them the unique creativity of their carboxy creators,
and their AI nanobots, Partners, working together on reaching journeys
end.
The
original Ark’s
left the homeworld at 1 tenth light speed. Traveling in all
directions for tens of thousands of years and in that time their AI &
nanobot components would be working tirelessly to increase their speed 0.2, 0.3, 0.4,
times the speed of light.
When they
reach a suitable planet they go into orbit and commence Terra-forming in earnest. They
seed the planet with flora & microorganisms, to bring the planet to
life. Many species will fail to survive, but many more will thrive.
Centuries may pass
before trees grasses and other oxygenating plants create a viable
ecosystem. Then, higher life forms, grazers and carnivores would be
created in artificial wombs under a vastly accelerated growth program, creating
mature creatures able to successfully breed and multiply within the year of
conception. Finally, when a stable ecosystem has been established,
humans would be raised in those same artificial wombs.
Their education would
begin prior to birth, from the collective knowledge of the
homeworld. Fully formed pubescent’s would complete their training
and be given free rein to populate and establish communities. The
AI’s would have previously created rudimentary habitations and factory units
ready for their use. The humans would be left to run things from
then on, while the AI’s concentrated on re-equipping and stocking the Ark for their
journey onwards to the next suitable planet.
Agriculture and mining
would be the AI’s initial objectives. Seeds & eggs taken
from the fittest would be used to replenish the Arks stores. Raw
materials, metals, chemicals, mined for future research, all stored and loaded
into the Ark.
As time passes their
speed would continue to increase 0.6, 0.7, even 0.8, times the speed of light.
The grand
project to populate the galaxy would continue apace, aided by the AI’s and new
currently unimagined Nanotech devices.
There will be
exceptions to this plan; so a caveat is required, to cover such
eventualities. Should there be failures in the AI chain; soft tissue
creatures such as humans may not be created. In which case they may
produce a pure machine society but, they would still be our progeny.

Year 1,982,076 ~
Leaving Home
I gaze up at the unchanging
sky, maybe for the last time. The sun a red fiery disc covers a
third of the heavens. There are hundreds of ships, like giant
mushrooms silhouetted against the ruddy backdrop. Once there was ‘day
and night’, you could view other stars in the sky, now only shades of red are
visible. Over the last two hundred years, the flotilla of ships has
been assembling in orbit. Ready to take us away.
We all know the sun has
become unstable and is entering its end phase.
Eventually, it
will expand and swallow up the solar system. So, soon we will be
leaving. We need to clear the Oort clouds outer zone before that
happens and need to be as close to light speed as possible, at the endgame, to take advantage of a 'once in star time' acceleration boost from the solar explosion that should propel us
towards our destinations which we may or may not reach alive, who knows?
The recently invented
inertia pods will, in theory, cushion soft tissue, and enable the ships to
accelerate for most of the journey halving the travel time. So, the
'stop-at–homebodies' will finally be embracing their greatest and final adventure…
Even so many opted to stay and briefly watch the end of the world; believing in divine deliverance.
We know there are now colonies established on most of the worlds around nearby stars, prepared to take in refugees
from the homeworld if we can reach them.
So, with months
remaining, we wait patiently for the telltale signal to GO…
