ok counter question... what about using spaceships as asteroids???
With gpt-3 no one will ever be lonely.
It was great working with you Isaac! Thanks again.
@@Bibibosh whats gpt 3? is it like mal0 ?
@@shardinhand1243 I think that would fall into orbital bombardment... which we have an episode on :)
Even after all these years your videos still give me a sense of hope for the future.
For real though I don't know where I would be if I hadn't run across them
Same
@@KageKatze I agree to it shows the man possibilities
Even with the repetitive climate alarmism?
I really appreciate the look at what people might be doing on an asteroid station/colony/ship. It's not 4 or 5 engineers being serious on a NASA mission, it's millions living in an area for generations. They'll have traditions, jokes, games, (hopefully small) conflicts. They'll form a new civilization. Maybe one as different from ours as ours is from human civilization a couple hundred years ago
There will be no conflicts, think of the security checks and IQ tests needed to get aboard a vessel that is not in the safety of our atmosphere. No one is getting on to be a labrourer. And there will be no addicts or anger management problems. You are right, it will be a different society, and there should be no need to even have a pistol on board. As long as ego's are kept in place it could be a successful one. But we will never know. It's a one way trip.
And that is another point, is Earth really willing to spent trillions to send a rock with a few people on a one way trip to alpha centauri. I posted this idea yesterday on a "Should we" do something way beyond our capabilities video so I had a night to think about it, the only way I can see everyone getting on board with that kind of project and sustaining enthusiasm for a decade or more is to put the Asteroid in orbit around the Moon so everyone can see it every night as the work is done.
But even those things are impossible right now. But a asteroid is the cheapest way I think, and safest. 🍁
(I'm also thinking double leg amputees' a primary candidates for Missions inside the solar system, lets see if they make a video about that in 24 hours). Basically they don't need as much of anything, room, food, oxygen, water...
@@streamofconsciousness5826 as long as there are two people, there will be conflict. Not necessarily war but unless we're all super engineered post humans by then, disagreements will happen and sometimes those can escalate.
Heck, anywhere you have isolated populations for a long enough period of time, new cultures will emerge!
@@Extra.Medium Though you would only get full scale war if your governing organization has a monopoly on the legal use of force.
It sounds like a great way to raise kids. And I just knew they would be leaving.
My favourite videos of yours are the ones with a longer storytelling segment, like this one or the one with the culture running away from the def-not-the-wh40k galaxy.
The Ship moves!
I'd love for Isaac to return to the theme of thicc space ships, like the asteroid ships in this episode.
Seems to me like the inevitable collisions at relativistic speeds and interstellar radiation require much thicker ships than are depicted in sci Fi.
Sleek and long would be better for a smaller cross section for collision, with a large portion of the nose being solid for radiation shielding/debris sheilding and angled for ricochets and radiation deflection.
Sidonia in Sidonia no Kishi is practically this ship not all sci-fi is star trek or from USA

Got a wide smile on my face when Isaac launching into his storytelling. 😊 Can never have enough of them.
Another informative and uplifting episode as always Isaac.
Yes, Isaac, please publish a book!
What the fuck? I was just wondering if such a concept were achievable, and now here's the video covering the very topic!
The cosmos works in mysterious ways.
if it's got a rocky metallic core it might be useful as a hull; if it's just one of these clouds of gravel you're better off harvesting the material for refinement
Can fill it up with expanding foam and Caulk lol
@@hherpdderp ...there is a real plan to melt them and spin them into rings... that's kinda like spray foam. Except with lava.
@@jengleheimerschmitt7941 how does that work? I mean is it different than my plan?
@@petevenuti7355 Fraiser Cain had this astroid-melter guy on last month. th-cam.com/video/Z-hH3-z56cg/w-d-xo.html
Put asteroid in carbon fiber net, spin it till it fills out the net in a ring shape... focus big mirrors on the ring to melt it as it spins.
@@jengleheimerschmitt7941 ok, yes, the net idea, the bag-o-rocks...
I mentioned my idea in the comments there as well as elsewhere here...
You had me at asteroid spaceships. 💜
Oumuamua was probably an alien spacecraft that chose not to stop at Earth.
They were like "should we stop here honey?" And Papa alien was like. "Noooo way.
Very bad neighborhood, in fact I am going to speed up a little."
as Clark Griswold once said: "kids, windows up"
Probably surveying. Going to make a bypass or something.
I blame a televangelist with a big transmitter and a hankering for Galactic currency.
Oumuamua probably is the most famous one in the Sol system.
To ourselves, black knight is lower-earth orbit spacecraft which from Anunaki period about millions of years ago.
I loved the extrapolation/storytelling you did in the second half of the video! As others have said, it gives me hope that the future will turn out well after all
You painted such a detailed picture of what life on an asteroid ship could be like. I really like that story-telling aspect of your episodes!
In Final Fantasy V, they use meteors to travel between planets.
I always thought it was kinda for story effect -- since it wasn't obviously a spaceship, it didn't make you immediately think of another planet.
I'm kinda surprised it's actually a possibility.
Love what you do Isaac, thank you!
Fantastic video! I never knew this type of ship idea was even a thing!
Also, gotta say, this is one of the first sponsored videos that I actually checked out the sponsor for. I was pleasantly surprised. I found my new news aggregator.
I really enjoyed the artwork Ken York put together of the Asteroid Space Ship. Kudos to him for the excellent visual.
Reminds me of the anime/manga Knights of Sidonia! Might watch that again at some point heh.
I absolutely adore and covet the beautiful storytelling at the end of many SFIA episodes. This episode's depiction of rock-dwelling explorers in a hotrodded asteroid has been the highlight of my week.
Tower of Angels, fortress-monastery home of the Dark Angels, first Legion of the Imperium of Mankind.
One problem I have not seen addressed is how to prevent a high power laser beam from vaporizing the light sail it is meant to push. We are talking _vast_ amounts of power, and even a very small percentage of that power being absorbed by the sail instead of being reflected would destroy it.
you would spread the power over a huge area, this is why you need kilometer long sails
That's the easy part, just tell the beam emitters your sail specs and they'll make sure they don't reach that W/m squared taking your distance into account, they can just modulate the power from their end, but honestly most of the time they'll run at full power because the distances are vast
@@dabs4270 exactly, you bring a huge sail and they can just focus the beam before your craft, you get the diffused beam as it diverges if you want the full power but lack the material to take it all with a smaller sail
I'd shave down my Asteroid to a perfect circle and build a Stripclub inside. I'll call it "The Ball Buster"
I see content from Isaac Arthur, i press instantly "thumbs up"
I’ve only watched the intro but now I’m hoping Isaac is going to talk about space faring dinosaurs
Now I'm wishing I did, though we did play with that a bit in the Silurian Hypothesis episode.
With genetic engineering we could bring dinosaurs back, then perhaps fast forward to what they may have evolved into. Then include them on trips to new stars!
That's what happened to them. They didn't get wiped out by an asteroid. They left on one. Neighborhood was getting over run by mammals.
Using asteroid as spacecraft make much sense like using iceberg as ships on the sea, simply put aren't made from the right type of material, and making a hull from titanium high quality alloy would be less than 1% of the price of fusion fuel for a interstellar travel.
Everytime I see an upload from you, the day gets a little better
Self running generators would be a great clean energy asset. And I mean multiple self running generators on each ship or craft. In case one or two don't work for some reason. We already have the tech. Just use it correctly.
Turning an asteroid into a flying hotel would be awesome. From orbiting planet earth to touring the solar system.
lol...if flying hotel and tourism ships are suggested to build this , century, we need more motherships as flexible settlements across the Sol system when we are traveling between the earth and the other extroplanets.
New recomendation for watching SFIA. Grab a drink, a snack, and a notebook to take notes of every good idea for plot points and scenarios for sci fi novels.
If you're reading this, thank you for all the ideas Isaac.
Orks: Those are some nice Roks.
Happy Arthur's day, I made a comment a few months ago on a community post and I asked if it would be possible to meet the dwarf planet haumea into one huge Interstellar Ark
Thouroughly enjoying your videos for a while now - please keep them coming!
I'm patiently waiting for the episode on Warp travel, Navigators and the Astronomicon.
With the new concept of ''bagging'' asteroids to keep them from flying apart when turning them into spacesteads, [giant rotating space stations] turning asteroids into starships seems not much more complicated than creating spacestead habitats out of them. After all, starships are such habitats, especially since the lengths of interstellar journeys requires crewed spaceships to be flying cities essentially.
It’s one thing I love in the series Stargate. In the 3rd series with FTL capable ships that can gather supplies to build the first modal Stargate a doorway opening a wormhole from one to another on another planet. Hundreds of these ships were made and sent off in every direction. After a century or 2 letting the ships have seeded a handful of planets in some galaxies the mother ship Destiny is launch to travel for 50 million years. Man I pray humanity is capable one day to work towards a massive goal like that
Ah, this was such a lovely classic Isaac! Loved the episode 👏💚
Great episode, let's dig and go.
OK it might be a little more complicated than that.
Future episode: did the Dinosaurs wipe themselves out by crashing an Aldrin Cycler Asteroid into the Earth?
For the world is hollow and I have touched the sky!
Could you use smaller objects in the target star system’s Oort Cloud equivalent as “anchors” to latch onto to begin slowing?
i like this idea interstellar spiderman
Problems include: latch onto with what? Materials only have so much strength before they snap. Also: Your anchor is likely to come apart under any significant stress, since you're dealing with asteroids/comets. You can't really strengthen the things; you're not sticking around, and anybody trying has to slow down to do so. If you're sending someone ahead with greater deceleration than you, why not just install a launching laser?
Can your ship take the strain? This is a very different sort of stress than that imparted by your engines.
Will your tethers hit something important when your anchor goes careening at an unexpected velocity when it comes apart?
Also: 'begins slowing?' If you're at a significant fraction of lightspeed, so is your tether, and we're talking about nuclear collisions when your tether hits your proposed anchor. Which doesn't even begin to worry about hitting the dust in the Oort Cloud at relativistic velocities.
Pretty sure the best you can do is a gravity slingshot, where you bleed off momentum to a passing gravity source... but that works best with deeper gravity wells.
@@boobah5643 you send in little robots the use a tiny amount of fuel to decelerate to the ort objects maybe they can shoot some kind of particle beams or tiny pallets of rock at the main fleet
Best way to make a house in minecraft is to dig a hole and pile up the stuff around you
Crazy Idea for you: Have you seen the Nasa video of 2004 BL86? The 2015 Earth-crosser's Goldstone radar image looks like a pretty smooth spinning sphere. It even "has its own moon" that might be a shuttle. Is it worth investigating?
Your voice sounds so different than seven years ago! Literally unrecognizable! It sounds like an octave lower now.
Space has to become way of life for all this. Still very interesting.
There was a scientist talking with John Michael Godier recently who came up with a concept that used energy in the solar and galactic wind to accelerate up to significant portions of light speed. I'd imagine that you could scale this up and make it very easy to quickly push a asteroid or massive lump of slag up to some useful fraction of light speed with a rotating habitat behind it or in a recession on the back end, you only really need shielding in front if you're so fast that the penumbra of the stuff you're shielding from is nowhere near your fragile things. It'd be a cheap, fast to get going, dumb, and effective shield against the biggest problems for near light speed ships; dust and radiation. You can use small scout ships or powerful radar to find big things like asteroids and planets far enough ahead to avoid, but there won't be many. If that propulsion mechanism does work then we could have the ability to send out colony ships maybe a century after we get established in the moon, though sourcing supplies from the asteroid belt and the Oort cloud would probably help cheapen that.
I got a little question on where my thinking mistake is. The Aldrin Cycler… does it really save any fuel? To dock with the cycler, you need to bring your mass to the same orbital speed, than the cycler is on. So you need the fuel to accelerate and to slow down at your target destination and should be able to make the trip on its own for the same fuel. It doesn‘t give you the shielding, comfort and so on, but for freight, it shouldn‘t make a difference. Am I making a mistake in my reasoning or is fuel not the relevant point with those cyclers?
And since I leave a comment on the same day, than your publishing date, I use the chance to thank you so much for your videos. They all have a wonderful length and deliver in your own wonderful niche every time. That is amazing!!!
Greetz from Germany, Chris
Just as an FYI, asteroids-as-cyclers is used in The Expanse to explain why 433 Eros became a backwater.
According to the backstory of the setting, Eros was used as a cycler to take ships between Earth (it gets pretty close, but doesn't cross the orbit) to Mars (it does cross that orbit) and the Main Belt (it reaches the inner fringe).
With a period of 1.76 years, it was a slow journey -- but space travel was always slow, and Eros was a place to put in, rest up, mine some resources and generally hang out until it got close enough to the destination that it was time for the (refueled and resupplied) ship to depart.
All of that changed with the creation of the super-efficient Epstein Drive, which meant one could get to Mars within a couple of weeks, and out to the Belt in a month.
That made 433 Eros largely redundant, and hence it became the Belter slum of the Solar System.
Arthursday!!!! Drink and snack ready.
NOTIFICATION GANG!!!!
Asteroid could be a good habitat too, but most aren't solid objects
it is amazing to contemplate humanity spreading out in so many directions, at so many distances, to ultimately become new species. definitely completely different cultures, first, then, eventually, different species.
Interesting that you chose an asteroid. I would think a Dwarf Planet would be a much more stable and significantly better option especially if you consider the possibility of placing a couple asteroids of different materials in orbit around it. Of course a Dwarf Planet would be significantly heavier, but it would allow for significantly more fuel storage without the need of tethering thus the asteroids turned satellites could be mined solely for materials needed to build the colony. Also the Dwarf Planet could be placed in orbit around the Destination Planet turning it into a satellite for the Destination Planet.
Your first statement in this reminded me of the 5th dr who episode where a spaceship crashed into earth and was the asteroid that killed the dinosaurs...rip adric... the forgotten companion
Sensors, telemetry, and packet radio for burst transmissions like a time capsule and satellite for any passing by.
If you combine the use of fusion reactors and self running generators, you'd be set for travel and emergencies. You'd have plenty of energy for many things, including an energy shield.😎
This will be a good one I can't wait
"Asteroids do not concern me. I want that ship, not excuses..."
Arriving at an alien civilization on an asteroid is a bit like arriving at The King's Coronation in a Yellow Cab.
Here is an excellent idea for an episode if a mula mula was one of these big asteroids and now it has been condensed down how big would the asteroid have been to make a mula mula the size that it is which is about 1,200 feet by 120 ft a ten-to-one ratio I don't know if you see this comment or not but I hope you do and take it into consideration to make a episode about this based on the episode that you are doing now
Perhaps someone has already done it. ʻOumuamua
I can already hear Orks boarding Hummie built Rokks
I want to visit this future.
I've always thought an asteroid would make an ideal spacecraft to use as an Aldrin Cycler between the Earth and Mars. If you get one big enough it could be developed into a luxury cruise ship with excellent natural radiation shielding. As a cycler it would require only minor course adjustments to stay in the enlongated orbit between the two planets and would be a delightful way to facilitate the Earth diaspora to Mars.
The "ship" @ 3:30 is clearly a Dust Buster.
"For the world is hollow and I have touched the sky."
Got lost on a 5 minute tangent googling that. Thank you it was worth it.
The idea of the Asteroid based ship kinda reminds me of a SpaceHulk, better get break out the Terminator Tactical Dreadnauts!
Ive never though about using an astroid as a ship but I been wondering for a few years about using them a space stations.
I like the idea of a starship full of yokel cosplayers.
As an avid sci-fi reader, this is like candy to me. Well done.
As usual, your subjects are fascinating!
Slightly off-topic, I just read Andy Weir's "Artemis," where the problem of lunar dust nastiness is highlighted. Due to the lack of atmosphere and weather on the moon, lunar dust is extremely sharp and jagged rather than rounded off and embrittled like most earthly dust. This causes it to wreak havoc on living tissue (especially lungs), mechanical parts, and soft materials - so you really want to avoid bringing it inside after a lunar EVA. Airlocks should have decontamination protocols - why not set your airlocks up to completely fill with liquids to clean and carry things away? You're already wearing a pressure vessel with life support, being in a vacuum vs being underwater won't be too terribly different to the human inside.

mini moons brought by drones, from the asteroid belt, used to push them into large orbit of earth. colonies form in a ring of asteroids, along with a defensive system. after time the ringer grow frustrated with lack of support. a revolution begins. the ring grows to almost encase the earth. the shadows slowly makes the planets and animals adapt. transports between earth and the spheroid.
Use gravity assists to knock an asteroid or comet towards a star and just use it for slow sailing.

Good book that explores this
Even the ad was excellent! -Did I really just say that?… Well, it was!
And now I think of asteroids as giant puddles of Space Stucco for doing my Space Colony Siding
Wow best episode.
For the world is hollow and I have touched the sky.
Make Psyche a spaceship!
Good job Isaac!
Fission fuel like u-235 has almost no radiation emission. It’s an alpha emitter, and thus only presents a hazard if you eat it. Spent fuel emits a fair amount of radiation , but given the overall radiation environment in deep space, even that is closer to radiation shield in behavior than radiation hazard. I would not use it as the inner layer of shielding. But it would be better than nothing for the outer layer. 7:38
Best series on TH-cam!!!
"For the world is hollow, and I have touched the sky!"
This is adding legitimacy to the *Oumuamua* visitor. The space soap dish
Using Spaceships as Asteroids.
So, based on the content of this video, something like the Sidonia from Knights of Sidonia is an ideal form of an interstellar colony ship? Nice. =^x^=
I love the idea, but I don't think it would work in practice. They don't seem to be solid enough to hold together.
I want to hear more about the backflip option, plz
I found the paper and the orbital schematic confused me a little. It looks like the cycle is kicked up and out during close approach for another close approach half a month later. The outward and inward legs would be half of a highly elliptical orbit, probably about five days for a total of about twenty four days, so the synodic period is 6/7 and it's only useful twice a year. If this is more like 2/3, it's usable every other month, nine of these would be in position ready once a week.
Probably a short of lunar orbit, highly elliptical, one third of a month cycler could be used once a month, every third go around and just add more over time. That's a five day trip
Orks: "We'z callz 'em Roks."
Your description of an interstellar asteroid ship reminds me of and sounds loosely inspired by the void cities from Hyperion. I imagine all those layers of graphene shielding could even one day hold in a thin but survivable atmosphere around the rock.
A survivable atmosphere would have to be fairly thick, unless compressed under a solid roof as the minimum pressure for humans to be able to breathe is thought to be 475 millibars, or just under half sea level pressure.
You cannot use graphene to build space elevators. They are hyper strong in one way, and brittle in others. It does represent the possibility of making super strong materials, but right now quite a bit more work is needed.
Where do you get your graphics for this episode?
Great show!
Asteroids are already built and some are N3O. Go big protection from cosmic radiation and put everything you need and set sail. It the best starship idea 💡
Honest. I’ve had this thought before. Snag a near-earth asteroid, hollow it out, build a habitat on it and a coupla engines. Imagine if we did that and an alien race sees it. Their thoughts will probably be the same as my neighbors when they see my loud rust bucket of a Bronco pull outta the driveway and then pull nearly a 1/2G acceleration up the hill.
I just realised that I was also thinking of the ultra capitalists of the Spacing Guild.
Makes me think of the Sidonia from the anime "Knights of Sidonia".
In a comment in another video of the same subject, I suggested using a parabolic reflector solar sail on a tether to melt small astroids into ribbons of basalt to build much if the shell of one of these ships. It seems like something that could be done cheap with today's technology..
What does what do you think
It is a viable power source, and so probably would work, though the issue is we need more hands-on experience melting asteroids and how that works at a practical level in a vacuum :)
@@isaacarthurSFIA not to mention tether systems!!
i really think that This is the best option for a space living civilization to prosper... 1 you can sustain much longer by attaching Engines or Large Ships to its surface and later build them into the rock structure where they would be needed. 2 the roid would offer not just materials... But protection from radiation... surface impacts or weapon bombardment of various design... 3 Entire Cities and living space as well as agriculterual space can be placed within the interiors. 4 Leapfrogging to other asteroids based on material needs for an ever growing Colony.... a much larger Structure could even be built attached to it to support a deathstar like Mothership or even an entire world could be built around it... even once it has been emptied of metals the sheer mass of it would offer your mothership Natural Gravity which is a problem for humans in space. The External built ship could even be designed to detach from it and release the exstinguished core into deep space. Like removing the inner part of a golf ball and finding a new Roid Core. a colony could thrive even picking up additional "core"
