Arthur's Law: if it exists, we can colonise it. If it doesn't exist, we can still imagine how we would colonise it if it did.

Fatalism is compliance. Optimism is rebellion. Resist entropy - Dare to hope.

When the Santa Claus machine is online, we can't let Isaac near it. He has way too many ideas for interstellar canister shot.

"Why I Haven't Written A Science Fiction Bestseller" by Isaac Arthur... Definitely gonna be a bestseller!

I've been watching for a few years now and I find it amazing how you can come up with interesting topics every week!

one of the most interesting interstellar spaceship designs in scifi surprisingly comes from james camerons avatar, with light sails, debris sheilds and massive thermal radiators for the antimatter engines used for deceleration after the 7 year trip to alpha centuri, the ISV venture star may just be one of the best thought out interstellar ships in popular science fiction

TY SFIA. I always remind myself that on Earth, we are already interstellar travelers. We just have to wait for our sun and another to cross paths.

Time dilation is allowing me to tell you this video is perfect a minute after it was posted.

Was it my imagination or did hear WH40k planet names. Also I can’t be the only person waiting on Issac to write scientifically accurate sci-fi novel. All he needs is a plot he has all the technical data needed for a great novel setting.

Awesome artwork as always ❤

I just want to say Issac, that your speech is NOT difficult for most of us to understand. I look forward to a bright Season 9!

I love your accent. It somehow perfectly works with these videos in such a weird and roundabout way, it's great.

Was once an optimist about these kind of thing. Now seeing so much chaos and divides all over civilization that it appears we will not be able to get together enough to accomplish this kind of endeavor.

Howdy science futuristic family. This is very informative. Never miss an episode. Started from the beginning all caught up.

Yes! 4 minutes and I see it! My personal record.

Fast means big... This reminds me of something I heard recently: The Enzmann Starship has been proposed at times of Apollo program. It was intended as the realistically first real interstellar starship, basically Super Orion on steroids: A big frozen ball of Deuterium in front, set of nuclear blast engines behind, each throwing 1.5 kt fusion bomb behind. 24-engine ship was supposed to be way faster than 8-engine one with lot of redundancies and ships were intended to travel as part of a fleet.

"Every colony can be thought of as being abandoned from the outset" That puts a whole different feel on it, don't it?

Omfg this is perfect to tide over my excitement for Kerbal Space Program 2. XD thank you as always Isaac!

Your videos addressing the issues of tomorrow and overmorrow* continue to delight me. *I recently learned that there is an actual word for "the day after tomorrow", and I intend to revive its use.

I came to this channel for the nuts and bolts of colonizing space

My friends are discussing whether or not fusion will happen and I'm just over here waiting for my plot of land on a blackhole powered O'Neil cylinders.

love your work issac. gives me dozens of hours of content to ponder on.

Happy new year Isaac, probably one the best knowledge bases for me online. You always bring up stuff I either forgot or never thought about Very conscientious

I've started watching your shows since around 2017 and I found great joy and many interesting ideas. Keep up the wonderful work

To hibernate people you may: 1. Induce sleep with medication 2. Slow metabolism with meditation 3. Soak cells with sugar and slowly freeze. That way crystals don't form. Frogs survive the process on their own and revive that way in the spring without any external help.

13:00 This is so freaking accurate, the differences in agile teams per environment, per project, per resources, per personality of team leaders and relationship style of team members could influence/breed the most exotic type of cultures! That's not even mentioning the differences in companies and industries! ..my head hurts

Arthur's law: if it exists, we can colonize it. If it doesn't exist we can build it, and colonize it.

This may come off as insulting but I mean it 100% as a compliment-your videos are literally how I fall asleep. I find the topics so fascinating and I have no idea how you pump out so many insanely high quality videos by the way but your voice is so relaxing and slow enough that I put your videos on whenever i need to sleep and I’m out in literally three minutes you’re literally magic I thank your for your service you make my life better 😂

Yet another informative and insightful video Isaac.

Intergalactic space isn't empty, it has stars all the way there, they are just further and further apart, reaching densities low enough that they are perhaps 10,000 ly between stars, but they are there.

Thanks for making these awesome videos!

Damn today's ending music was epic.

Your videos help me out alot with my sci fi dungeon and dragons ideas💡 💯💪🏽

Magnificent video, I hope one day someone creates a Sci-Fi fantasy story in which mythical species/legendary creatures colonise the solar system and other planetary systems in an interstellar colonisation campaign (rather than by humans) perhaps, if not certainly with Speculative Evolution (aka Speculative biology) being employed or used in this story.

You can go faster by brute forcing the fuel. It might take 10,000 times the fuel to go twice as fast but 10,000 times the resources might become available.

Season 9 let's gooooo 🎊 Happy New Year Isaac

Yes! A new SFIA episode!

This is paradigm-shifting material. A book I read on the subject was an awakening. "Galaxies United" by Olivia Whitestone

Happy New Year!

I watched the channel for over a year. I must say Isaac Arthur has a perfect documentary voice. Brain food and relaxation in 1 package ^_^

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.

Another great one. You make 35 minutes feel like 15. I don't know what dark arts you practice to do so, but I'm glad you're using them for good, not evil.

Maybe in earlier episodes i noticed a slight speech impediment but to be honest last few years you speak better than most people i know. I look forward to another 9 years from you mate.

Posted 42 minutes ago? 42 - it's a sign, destined to watch tonight!

Awesome artwork as always ❤🎉

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.

The IA Algorithm 1st rule of Warfare are also a pillar of the channel. And the Channel’s missiles.

Thanks again friend!

Great episode. Good to see the visuals sometimes as usually watch on Spotify

I'm here for a drink, snack and the most exquisite content.

I love the Gardener ship concept Even they never become reality - it's a great concept for sci-fi

This is a video I've been waiting for :p

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.

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.

Whew, here I was, worrying about space pirates on my ark ship, and you just throw a logic wrench in it.

Add a bootstrap Law concerning previously sent out slower than light ships, to outfit them with recent updates of drive technology. Pioneering spirits should never be wasted or changed psychologically to suit your needs.

Loved: "its still a good strategy to learn to get along with your niegbors"

I think we will become space nomads. Taking what we need from the planets and moving on to newer planets.

Every space colony will need an expansive maternity hospital.

Interesting thing is that I literally understand everything even though I'm not from English speaking region but I tested and asked my friend today if he understand you and he said that he doesn't but he clearly needs from person to speak slowly and clearly to understand (his words) but he didn't understand anything but I understand you since my first listen long time ago and I enjoy in every single episode, just turn on and lie down in my bed before sleep!

Xenoblade Chronicles X does something similar to the cloning and consciousness transfer via mimeosomes, in which they project the consciousness of their colonists into androids constructed in the likeness of said colonists.

You inspire me Arthur on a personal level. I’ve been a huge fan for years. Thank you for the content

Oh to be a fly on the wall in the future. Great stuff 👍

Another great video by issac arthur and love listening to a video dealing with the bright future of humanity. Issac needs to collaborate with scyfy series.

Great work

Hi Isaac! have you looked the video, how to conquer/colonize the universe in three easy steps? it's a great watch!

If we are talking about the interstellar colonization policy for the humankind, first, find the other star system with the good planets by putting the space telescope. Second, put the drones in the surface of the planets and their moons. Mostly likely, we will use the generation spaceship if we are not achieving the fastest than lights engines. Plus, genetic engineering is one of the policy for interstellar colonization.

Isaac you might have a speech impediment but it doesn't hurt the quality of the videos at all. You have the voice of a radio man.

I hope I get to see people living on other planets.

By the time the solar system is populated enough (0.1% dysoned) that colonists are heading out it will be trivial to make a light highway to push them (its all done with mirrors)

He sounds so much more confident nowadays... anybody else picking this up

You send your laser stations first. Use one laser station to push the next laser station to its destination so it can decelerate incomming shipz from midway.

I always imagined we Humans living in Earth orbitals, moons bases in my time, yet they just stopped. We, All Human societies, are gearing up again to leap into space. I do expect to see an order of magnitude leap in technology, space mining, and orbital/moon construction. But that all takes a great deal of time, but I believe we can do it safely and be spread out quite a bit in ou own solar system by 2300. Excelsior!

When colonizing another planet, the best way is to adapt ourselves versus teraforming the planet. Combining our DNA with the terrestrial indigenous beings. It might be a multi generational adaption to get the best fit to our new environment. It is possible we might not fully reconize our ancestors as our own kind in the end result. Unlike a Battlestar Galactica type scenario where everyone looks and is exactly the same phylim and species.

As with most things in life: team strategies win long term.

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,

Your accent is soothing to myself and I'm somewhat of an amateur rocket scientist myself so Godspeed snd god journey :)

Hey issac have you ever considered doing a video on the Dark Forest theory and how it relates to the fermi paradox?

Imagine a combination seed & gardener ship where the crew are all uploads or folks in cryo, or both. They spend their time in VR perhaps running a little slow to pass the time relatively quick, popping out from time to time for maintenance tasks, or whatever. 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. Would likely speed up their repopulation efforts!

Hey Isaac - do you have any videos of the technologies that is needed to transport humans ? Like details about the water, food, living space, etc.

A Ai would be very useful. It could have access to all Data on earth prior to launch and you could have a natural conversion with them instead of typing commands

Your videos are not only educational, but also full of beautiful sci-fi art and design, which I love. Keep up the good work and have a great 2023!

We are even intergalactic travelers already. Only another billion years until we get to Andromeda. Good intergalactic real-estate I hear. With A LOT of drinks and snacks we will easily make the trip.

Ooo a new video thanks brother! 😊

Thank you

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?

* IF * we are early in the rise of galactic sentient life, it would be our duty to expand and seed the galaxy like Johnny Apple seed. Eventually the people on other worlds will evolve to be Aliens/different species from our own.

: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 😂

Isaac I would feel blessed if you wrote a sci-fi novel on any topic of your choosing

If those thousand gardener ships split up every time they stop over and seed a system then they're a million after ten such passes and a billion after after twenty, having seeded about two billion systems

As you talk about the immortal ship population issues, i was thinking the likely solution to that (which would make a great show) would be for people to take a sterilization drug, and if they choose to not take it and have children, they would be choosing to cease the immortality treatment and would love out their days with their children, then die. I'm envisioning an accidental class system evolving as a theme in the show.. the og immortal crew, and the population who's ancestors refused to take the sterilization so created a breeding population bloom which was no longer given the option of immortality, and strained all the resources to the breaking point.

This is most possibly the coolest channel on the KZfaqs, followed closely by LGR, and Forgotten Weapons. I love your work, Isaac, please keep it up!

Good video.

Yeah! Aforementioned host! All hail the algorithm!

Have a great ninth season! :)))

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!

Most worlds are way too large or mass intensive for us to colonize the higher the mass the higher the gravity

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

We need to begin the trip out with tech to send and receive updates and improvements to drive and other technologies.
