Interstellar Colonization Strategies

Colonization may take much longer this way but requires much less engineering and energy to achieve (no new science or engineering is needed).

Thanks for another thought-provoking video. Thinking of colonization, the 1st craft could be a robotic probe. The robotic craft could be sent at a high speed as it could take higher acceleration and deceleration maybe even using aerobraking, gravity braking or other methods. The robotic probe would be smaller and possibly cheaper than a massive colony craft. Once the robotic craft arrived it/they would arrive and then construct the electromagnetic or laser accelerator/decelerate. The human colonization craft would then be sent a high speed.

Ultimately the most feasible strategies for interstellar colonisation are A) the gradualist approach: Colonise the Oort Cloud first, then just keep going until you've colonised the next star's Oort Cloud. Obviously this doesn't benefit people living in the inner system much, but interstellar colonisation is so slow it's not so much _colonisation_ as a migration, and was never going help the inner-systemers anyway; and B) the wholesale strategy: embrace the migration and move one's entire civilisation to another star, either by abandoning one's star all at once, or by just moving the star itself closer using Nicoll-Dyson Beam (this also works for gas giant planets for a much faster solution on a smaller scale). I'm generally of the opinion that interstellar colonisation is a purely far-distant future thing. There's just no reason to go somewhere literally hundreds of thousands of times further than even the most distant reaches of the Solar System when the Solar System itself is so vast and readily colonisable unless every last asteroid and comet out to several light years have already been colonised.

I enjoyed the back/flavour story from the Macross series. After the war, colonization was both seen as a way to preserve the species, but also lower the strain on the very damaged Earth. A mass exodus happens, with huge numbers of people reaching out for new homes. The mass exodus part in particular I could easily see happening in “real life” as well. I wouldn’t be surprised if there was something like a 20% drop in world population very quickly if there was the chance to set out on a large scale. The Macross colony ships themselves are vast in scale, with “smaller” trailer ships in tow with specific purposes, like long haul trucks on the highway. There’s also a swarm of smaller ships in formation for factory work, defence, resource gathering, scouting, etc. These grand fleets are independent and self sustaining, are sent out from points of previous colonization, in all directions, but also keep a relative parallel course in groups to transport people, technology, and information back and forth. The map of travel kind of looks like a humongous spider plant. They do have FTL jump drive technology in this series, as well as many other sci-fi perks like artificial gravity, so it’s not exactly grounded in realism. The Macross Frontier herself would be a utopia living aboard her by the look of it.

Issac, I think it's just about that time to do an updated fusion episode, They were successful of generating a 50% net positive of energy using lasers and sometype of hydrogen pellet, I've been wondering what net positive they really pulled off when you consider the power to create the hydrogen pellet, They are going to make another prototype just on a much larger scale, Hopefully this is the jump we really need to make a workable fusion power plant to generate power to the grid, I can only imagine they will only get a larger net positive of electricity over some more time but it makes me excited that fusion energy for a lot of stuff is not to far off,

[@massimookissed1023]

The fuel pellet put out 50% more energy than the laser light had that hit the pellet. The lasers and their cooling systems used about 100x more energy than their laser light output, and converting the fusion energy output into usable electricity is not gonna be anywhere near 100% efficient.

When they get where they're going people wake up and start building, offloading, etc. When it comes time to repopulate the ship, people have their kids virtually and let them grow up in a frame jacked VR world if needed, only to get downloaded into a combination synthetic and biological body as required to continue along with the ship, or get ready for the next colony site.

[@geoffreymartin6363]

I love your "peculiar speech impediment and accent", it's relaxing as shit and very easy to understand. My favourite concept of interstellar colonization solves the confusion of the War of the Worlds aliens being so dumb. If it turns out we're incredibly late to the game of life, and a species has already has basically infinite energy and has noticed the lack of similar level civilisations, then they may decide to send fleets to EVERY possible habitable planet in an entire galaxy, or as far as they can reach, perhaps from another galaxy. If the chances of military loss or biological destruction like as seen in the movie are low, and the costs are relatively minimal, then swarming out with a full invasion force to every habitable system is the best possible strategy. If you lose 1 out of 10 planets, you still have 9 out of 10 planets -- and when those who won against you are ready to expand, you're going to have them surrounded, out resourced, and have had time to solve the weaknesses that caused their loss. The far far future, your species controls the entire galaxy with no competition. It's capitalism, and invasions of worlds like Earth are acceptable losses. This species plans millions of years into the future, so to bury machines centuries/millennia ahead of the invasion would be inconsequential. To lose a fight for the fate of a world with no retreat under strict quarantine would only mean some time having fun crushing ants for your soldiers. They may not have even been at full strength, if you can cross a galaxy you can afford to send a fleet with substandard weapons if they're still good enough to take the planet most of the time. It'd be very easy to kill off a planet from orbit for them, and if the fleet failed, no loss, microwave the planet enough for all mammalian heads to explode and come back when things cool off. A slightly more terrifying explanation is if all that's true, a billion alien ships crossing from Andromeda to take a thousand worlds over a million years - but their risks of loss are much, much higher, yet they still think it's worth it. It's worth it, because they're desperate. Because they're not conquerors. They're running. Running from an interstellar war they're losing. They're a military force, regrouping, with the knowledge they'll need to control every world they can to survive what's coming.

With dynamic soaring there are also interesting ways to launch faster than the solar wind with them up to 2%c.

watched this over on Nebula 'which still doesn't have a comment section :( ' was wondering how the mass and resources these various ship concepts compare to the current manufacturing capacity of the major players or even the entire world's mining launching and manufacturing capacity. seems like the smallest version discussed might be buildable by either the USA, China, or the EU with a major commitment in only a few decades, while the largest would require a few centuries after increasing the solar systems total capacity by a couple orders of magnitude. i may be way off on my wild guess here just curious about the timeline and resource investment a fleet of gardener ships would take

Every space colony will need an expansive maternity hospital.

Some things that should be taken into account are the body's limit to acceleration, based on this I could imagine that a ship would be accelerating at a rate that is equivalent to the speed of gravity up until the ship is unable to continue that acceleration, the passengers of the shop would then be placed in cryo pods till the point of deceleration, this would happen in which the ship would do a 180 degree turn, so that the floor of the ship would always be the same direction, and to decrease the complexity of design. While this is all happening, a separate cargo ship is heading to the planet at a higher acceleration then is possible to handle by humans to set up the infrastructure needed for human civilization.

Another thing I would consider is the aspect that during acceleration, the passengers would be in a separate ship that is smaller, as mass makes a huge difference in acceleration, this would be set on a course to align with a larger ship that is following along a set route. Once the ship is docked, passengers would go into the larger ship for hibernation up until the point of deceleration when they would go to the smaller ship to colonize

The largest moving "vehicles" so far built by humans are our huge, nuclear powered Aircraft Carriers. And these max out at about 1,000 feet in lengh. (Or less!) So it would seem to me that space vehicles of 1,000 or 1,500 feet in length just might soon be within our engineering capabilities. But, as to speed? Today we might have technology (with foreseeable improvements) to accelerate to from 0.1% or possibly 1% of light speed. Maybe. Thus to reach even "The" nearest star could take 4,300 years or 430 years. So, I'm not yet eager to buy my ticket and take my chances!

:3 you don’t have anything to worry about with the speech stuff fam, been here since subtitles and you’re better at speaking than me 😂

What about common necessities, assume on Nuclear Disaster You would have something as this: sleeping bag, vessel, gas dispenser, lighter, mobile phones, WiFi connection, external batteries, hygiene products, towel paper, respirator, garbage bags, first aid kit, flask, water, canned foods, personal documents, cash, personal photos, flashlight.

At current birth rates, even if we get perfect eternal life, it'll take about 8 trillion to 32 trillion years to fill the galaxy with a mere 10B people per star system. Assuming each system gets a Dyson Sphere, there'd be an Earth's surface area for every 20 people with so few people per system - but do you really want to take longer than that to fill the galaxy?
