22:30 reminded me of an anecdote on the building of Brasilia, Brazil: there used to be an industrial size concrete-mixer that would mix concrete non-stop (yes, 24/7) until it broke & had to be replaced. the calculations showed that it was less expensive to buy a new concrete-mixer ever 30 days than turn it off for maintenance. so I can easily see companies shipping these kinds of robots to the Moon periodically & using them until it stops working (or its marginal production falls too low) & needs to be replaced.
So we are currently living inland on the plains, with some very minor settlements on the coast. We still tend to build the ships and truck them to the sea before setting sail Very close to the coast. But once we start settling fully the coasts and harbors, getting out to sea and the wider ocean becomes so much easier. Most of Human civilzation resides close to or on the coasts. I would expect space to fairly similar.

Is anyone else getting weird video lags every ~5 seconds or so? It's happening for me in 3 different browsers, at both high and low resolutions. The audio is fine, though.

I've followed your stuff for years and I've got to say - your sheer output is incredible. I don't know how you have the time to create all of the stunning 3D visuals to accompany every concept you describe.
Another awesome video and we Another series dealing with becoming an Interplanetary species like the expanse. Developing and colonizing our own solar system is a lot more interesting than what space opera talks about.
Railguns on the Moon. One of Heinlein's most perfect predictions. And, while she might indeed be a harsh mistress, Luna is also so important to everything we need to do going forward; sort of like the crazy, hot girlfriend who is also incredibly rich . . .
That’s definitely one piece of technology we could use as a ship in orbit with arms on the outside and as the ship orbits its arms can grab pieces of space just. The arm puts it in I call the mouth where inside is technology that dismantled everything down to individual stuff. Then can melt it down and stored for pickup with another ship that can take the materiel and 3D print parts for space infrastructure or ships. With a small fleet we could clean earth orbit up and reuse it all
While I know space junk was covered a lot in Orbital Infrastructure I think it's more important than a passing mention when it comes to Colonizing Cislunar Space and the Lagrange Points. Not sure if it warrants an entire episode but giving an update on the kind of technology that could be used for cleaning up space junk. Drones for sure but how they could go about it would be interesting to know.
One could only wonder how Isaac Arthur is able to create so many, such high-quality productions! One might begin to think, that Isaac is, in fact, a Jupitar Brain! :O :P :D
I really don't get the fascination with Mars. I have little to no interest in humans colonizing Mars. Now the Moon... I'm 100% for colonizing Luna and the area around space.
Why not both? If you can colonize the moon, you can colonize Mars. The requirements really aren't very different. Arguably, the moon may be worse, due to the extreme temperature variations and extremely long days and nights.
The appeal of Mars is long term, it would make a better permanent home than Luna. That said, we have to learn to walk before we can run, thus we need test beds close to Earth to figure out the kinks of long term space settlement, so a few spacesteads in Earth's orbit and stations on Luna are the best near term ideas.
Hi Isaac, have you ever read a Japanese sci fi novel series called Crest of the Stars? Maybe it's just me not reading enough novels, but this one is the first I read in which a galactic empire doesn't care for planets. Its first class citizens are all transhumen who live their entire life on space habitats. When the empire "invade" a planet for land marking purpose, they just have their millions of star ships do a drive by without firing on anything on the planet and announce to the planet that they have conquered the planet. In terms of scale this novel is quite good.
I don’t think this was the first time watching this video, but he talks about space expansion to orbiting habitats. In my comments on videos about the expansion of human beings to space, I had to point out the need for Earth grade gravity, and the use of Hyper Gravity Vehicle Habitats. In this video, Issac talks about the fact that we will have our first Large Scale Space Habitats not too far from Earth… He doesn’t tell us about how we will get thousands of people to want to go through the agony of getting to orbit or wanting to stay there other than overpopulation. Of course, there will be the few who want to be there just because it’s outer space and fewer who are in shape and trained to go to orbit. Yet, in hundreds of years, humanity will need to expand to orbit just as we will run out of land on Earth for more land in space, man-made lands, habitats… Issac talks about what resources we’ll need from space, as I have commented that we will need a reason to mine the Moon and asteroids more than science experiments. Relativity Space will most likely be one of the first to start space mining to make the 3D Printing done in space more affordable, but that is done in space for space use… What we need is something to mine and bring back to earth like rare Earth elements and the Helium 3 for our future power stations, but I’ve heard about cheaper and less effective nuclear power stations. Cheaper nuclear power plants brought to us by Tech for Luddites; ua-cam.com/video/C6BGLgJY0Wg/v-deo.html Will the new cheaper power plants be cheaper than mining the Helium 3? The use of Helium 3 in the Moon's power plants because we mine the Helium 3 there, but the Moon is radiated from space radiation, so will it be easier to use the spent nuclear waste that we already have? We need a rich billionaire to fund the development of the mining of Helium 3 before we move to Mars… As I’ve commented about the need to travel through space faster is needed before we start the big space projects. It sounds as if we will be using Nuclear Thermal Propulsion soon so that within ten years we can get these projects moving faster through space… I copy all of my comments to; thenewmars.wordpress.com/ for your easy reading…
Wouldn't it make more sense for rotating space stations to use the momentum from the catapulting of space vessels to maintain their rotation or even to assist with station-keeping instead of having to counteract that momentum transfer with the burning of fuel to create yet another momentum transfer?
ISAAC, I just had the weirdest thought (and no, I'm not high). I can actually imagine using your recordings as something soothing, to help an infant go to sleep. Has anyone ever suggested something like that to you? I mean, of course anyone can read nursery stories in a soothing voice, but how many people could have their infant sitting there listening to talking about colonising space?!? I'm an Aspie, so thoughts like that tend to simply cross my mind. Thank you for your wonderful content, as always. Cheers!

As a metallurgist, I scoff at a robot lugging around an aluminium refinery in a vacuum. Check out the electrochemistry of aluminium and how it needs electrorefining in a reducing molten salt environment.
Great video! So how soon can we expect all this to occur? I'm guessing not in my lifetime unfortunately. I think I'll be lucky if I make it into space at all! In any case, I'm glad to see that some folks are still seriously considering our prospects as a space-faring community.
Looking at that cis-lunar space map, L3 would be the perfect place to set up solar powered factories. Smelting plant to process all that space ore into building material.
I think Lagrange points push outwards, like antigravity, instead of attracting, like regular gravity... it's a vortex made of 2 gravitational fields opposing each other
A potential use for cislunar space are telescopes. (Mentioned briefly) LSST Vera Rubin is going to be super affected by the new satellite constellations being put out by spacex and Amazon. Also we can try terrascopes, David Kipling's very interesting idea.
"Cost" is a relative term in this context! Should we even be thinking of $ value in a product or should it be a function of manpower to produce the system that produces the system that eventually produces the product? Obviously we are in a cash economy here on Earth but other models become available and may even be preferable in a post scarcity economy ...... which is what this is creating! We may even get a dualistic model like we see in Star Treak where interactions can be entered into on a monetary basis but general living within the system is cash free!
I think talking about cost is still valid. Even in post-scarcity, you want to discourage certain behaviors (like ordering 1000 hamburgers at once from the replicator). If you use a quota system, then the currency might be quota credits. (Example: I'll give you 2 kJoules of my energy quota if you say "Make it so".) What the currency IS matters less than the ability to signify value. In a post-scarcity world, influencers might finally get the "exposure" currency to catch on.
Dollars are what we've got. Considering the number of political thinkers who can more easily imagine the end of the world than the end of capitalism...well, it's a cost factor that's easy to research, share, and understand.
There is a $ cost element to set up for sure .... but once you get past 1st generation production it becomes availability rather than cost! The 10,000 burger order at the replicator could be stopped by peer pressure or even summary execution ... or anything in between! It is a bit like the free chocolate biscuits available for workers to eat in the chocolate biscuit factory. At first they scoff them down but it soon pales and people only take what they want/ need!
Star Trek didn't invent anything. It was only practical execution of ideas already debated on Earth, though I would not mention the name as Americans get diarrhea in the ignorance.
@@timothymclean It shouldn't be surprise, because capitalism is absolutely natural like gravity. Problem are only extreme interpretations if not worship of something what is just simple logic. Even in Star Trek there was a trade between civilizations and local exchange on Earth (mostly handmade goods). It is just that people have guaranteed Social Welfare as resources and production was so cheap, that you didn't need keep competition to keep costs even lover.
@@PGGraham Theoretically, if we have nuclear propulsion, we can accelerate at 1G for the first half of a trip and slow down at 1G for the second half. However, those are short trips of less than 100 light-years. There is a maximum speed for the engine, and once we hit it, are stuck at that speed until we reach the slow-down window.
Practically speaking, only with a spaceship drive that consumed basically no fuel. Not "perfect conversion of matter to energy" no-fuel, "probably violates conservation of energy and/or momentum" no-fuel. If fuel is a concern, people are going to point out that you could get superior or equivalent performance from short burns and lots of coasting.
Having learned that the Earth's hill sphere is around 3 000 000 km I thought about connecting orbital rings in a line to make a cooling disk. I estimated that it could easily radiate away 10 000 times the sun light which falls on the earth's surface and thus we could become with this at least 1.4 or 1.3 on the Kardashev scale. One part for cooling and one part for collecting sun light but the interesting part is the cooling function. I estimated 400 W/m² to be radiated away at cozy temperatures.
I have yet to read the NSS report, but I'd like to know what we're going to do with the Van Allen radiation belts if we're going to colonize cislunar space.
Translunar cycler picks up KE through continual Lunar slingshots then transfers this via a 1000 km zipline to suborbital capsules lofted from Earth that then take mag-break rides at 3Gs. You could build 1300 of these for a interplanetary trip at suborbital launch cost every half hour. After a decade's operation this is a mere million humans roaming around Sol system. The same system helps lift cargo from your station on Luna's trailing edge.
Re: Solar sails. Silver is 5% more reflective than Aluminum and, due to it's high ductility, can be made into a very thin foil. Also, the moons regolith contains more silver than high grade ores on Earth so it can be sourced and delivered to a ship's in-space construction site cheaply. Silver should be considered for solar sails as an alternative to Aluminum.
I understand that some people are not wired to pronounce the "R" sound, and I hardly notice it, but what does catch my attention is your pronunciation of the word "volume" as "valume". I hope my comment isn't rude or annoying. I love your brilliant work!
about that lunar rover swarm prospecting for resources, I can imagine a company that builds and sends the robots to the Moon with telepresence features, then allowing folks on Earth to try their hand at driving the rover around for a cost like a monthly subscription game. Heck, if people find resources the company might allow the finder to keep a portion of the profits and we have minecraft on the Moon (well, all mining, not a lot of crafting)
I wonder how those birds are flying in that rotating station. Artificial gravity by centrifugal force keeps thing on the ground, but without an attachment to the ground, you're in microgravity, right?
No, there is no magic force that keeps the air from spinning with the structure that encloses it. If a part of the spin axis is in "open air" (contiguous with the air above the "landscape"), then the birds would be in "microgravity" THERE. Below (outward from) the axis, spinning with the enclosed air gives you spin gravity; more the further from the axis. At a moderate distance from the axis, a bird (or a drone or a vehicle) might be able to remain objectively "motionless" by flying anti-spinward against the motion of the internal air. Technically, even at the outer floor, moving anti-spinward relative to the floor reduces your "weight", and moving spinward relative to the floor, increases it, but on a torus or cylinder with a large enough diameter to produce 1 G with 2 or 3 RPM, you'd never notice this effect at walking speed.

@isaac, can you do an episode on the possibility of singular living or artificial entities the size of galaxies or larger(galaxy to local cluster and each step up) eventually reaching the possibility of organic, artifical and/or synthetic creations so large that it's beyond clusters possibly taking up whole voids or even filament and wall sized taking up significant chunks of our know visible universe? Kinda dipping into the lore of marvel comics and trying to assign a physical scale to their manifestation. Thanks!
I feel like the Lagrange point between Mercury and the Sun would be a perfect place for a solar wind collector or other scientific instruments you may want close to the sun.
No such thing as renewable. The future is nuclear. Solar will be more affordable, but it is the waste photon ejection of the sun's fusion core. If we build a space elevator, we could add solar panels the size of a city on it and probably run the nation that it is tethered to, though.

Only if ""translunar" meant "interlunar". Even then Mars has two moons and is closer.
I keep getting flashbacks to Anno 2205, it amazes me how perfect the game imitates this real-life systems.
Great game.
Great video, thank you!
I love the witty quips at the beginnings of these videos, but this one was especially good.
I think the most useful definition of a "multiplanetary species" is that of having a human presence on another planet which is capable of surviving and growing on its own.
Wow, your speech have improved so much over the years! All that hard work paid off ^_^

Me: what if you're wheelchair bound? How do you make that first STEP? XD
@@PerfectAlibi1 i think in a wheelchair when a wheel makes full circle is counted as a step, that is if you mark a point on a wheel and how much wheelchair moves untill that point returns to its starting place. But you can call it first roll...i guess...
One should never let anything stop him/her.. if steps are not possible..then roll..if not roll..then crawl... but always there can be movement.. xD

Is anyone else getting weird video lags every ~5 seconds or so? It's happening for me in 3 different browsers, at both high and low resolutions. The audio is fine, though.
Yeah, I see it too. Mostly noticeable closer to the end
They're render glitches
upload glitches, youtube gets them sometimes in the first 24 hours on longer videos and I had to reupload this last night, normally I put them up a week or more out
love this series so much
The last time I optimized paper clips this early they were papyrus clips.
Oh, hey, Joe Scott shoutout!
It's not Thursday until the SFIA video is uploaded.
Happy Arthursday
Thursday is payday only once every two weeks, but every thursday is SFIA day!!! Woot woot!
I've followed your stuff for years and I've got to say - your sheer output is incredible. I don't know how you have the time to create all of the stunning 3D visuals to accompany every concept you describe.
He's got people for that
One for the algorithm, love these videos and finally caught up lol
Another awesome video and we Another series dealing with becoming an Interplanetary species like the expanse. Developing and colonizing our own solar system is a lot more interesting than what space opera talks about.
Always a good day when there is a new Isaac Arthur video!
Railguns on the Moon. One of Heinlein's most perfect predictions. And, while she might indeed be a harsh mistress, Luna is also so important to everything we need to do going forward; sort of like the crazy, hot girlfriend who is also incredibly rich . . .
Just yesterday I wondered when another part of the upward bound series will come out... And here it is! Thanks isaac
Get to the lagrange points. That's where the von neuman probes are located
Refound this channel and subscribed. This video informative, but the graphics and music really make it something fun to watch. Thanks!
I love this show!
Well thought out.
Always in awe of your content and research. Love your channel
Another really fascinating video!!
Thanks for this Issac!!
I really like the Upward Bound theme at the start
That’s definitely one piece of technology we could use as a ship in orbit with arms on the outside and as the ship orbits its arms can grab pieces of space just. The arm puts it in I call the mouth where inside is technology that dismantled everything down to individual stuff. Then can melt it down and stored for pickup with another ship that can take the materiel and 3D print parts for space infrastructure or ships. With a small fleet we could clean earth orbit up and reuse it all
Happy New Year Isaac! Well 5 hours into to it at this point. New Zealands time zone is fun
While I know space junk was covered a lot in Orbital Infrastructure I think it's more important than a passing mention when it comes to Colonizing Cislunar Space and the Lagrange Points. Not sure if it warrants an entire episode but giving an update on the kind of technology that could be used for cleaning up space junk. Drones for sure but how they could go about it would be interesting to know.
Maybe the space junk could be salvaged
Thank you for FINALLY helping me understand Lagrange Points
One could only wonder how Isaac Arthur is able to create so many, such high-quality productions!
One might begin to think, that Isaac is, in fact, a Jupitar Brain! :O :P :D
Yet another informative video as always Isaac.
I really don't get the fascination with Mars. I have little to no interest in humans colonizing Mars.
Now the Moon... I'm 100% for colonizing Luna and the area around space.
Why not both? If you can colonize the moon, you can colonize Mars. The requirements really aren't very different. Arguably, the moon may be worse, due to the extreme temperature variations and extremely long days and nights.
Oh well, thanks for letting us know. We can rearrange everything for you.
The appeal of Mars is long term, it would make a better permanent home than Luna. That said, we have to learn to walk before we can run, thus we need test beds close to Earth to figure out the kinks of long term space settlement, so a few spacesteads in Earth's orbit and stations on Luna are the best near term ideas.
I want to vacation on the moon in a glass high-rise tower and I want to go swimming in a pool on the top floor!!🤙😁
@@michaelcox1071 I know right? It's a little late now! Wish he spoke up about 15 years ago...sheesh.
Hi Isaac, have you ever read a Japanese sci fi novel series called Crest of the Stars? Maybe it's just me not reading enough novels, but this one is the first I read in which a galactic empire doesn't care for planets. Its first class citizens are all transhumen who live their entire life on space habitats. When the empire "invade" a planet for land marking purpose, they just have their millions of star ships do a drive by without firing on anything on the planet and announce to the planet that they have conquered the planet. In terms of scale this novel is quite good.
Got my snack and drink!! “Arthur-Thursday’s” has arrived!
I don’t think this was the first time watching this video, but he talks about space expansion to orbiting habitats. In my comments on videos about the expansion of human beings to space, I had to point out the need for Earth grade gravity, and the use of Hyper Gravity Vehicle Habitats. In this video, Issac talks about the fact that we will have our first Large Scale Space Habitats not too far from Earth…
He doesn’t tell us about how we will get thousands of people to want to go through the agony of getting to orbit or wanting to stay there other than overpopulation. Of course, there will be the few who want to be there just because it’s outer space and fewer who are in shape and trained to go to orbit. Yet, in hundreds of years, humanity will need to expand to orbit just as we will run out of land on Earth for more land in space, man-made lands, habitats…
Issac talks about what resources we’ll need from space, as I have commented that we will need a reason to mine the Moon and asteroids more than science experiments. Relativity Space will most likely be one of the first to start space mining to make the 3D Printing done in space more affordable, but that is done in space for space use… What we need is something to mine and bring back to earth like rare Earth elements and the Helium 3 for our future power stations, but I’ve heard about cheaper and less effective nuclear power stations.
Cheaper nuclear power plants brought to us by Tech for Luddites; ua-cam.com/video/C6BGLgJY0Wg/v-deo.html
Will the new cheaper power plants be cheaper than mining the Helium 3? The use of Helium 3 in the Moon's power plants because we mine the Helium 3 there, but the Moon is radiated from space radiation, so will it be easier to use the spent nuclear waste that we already have? We need a rich billionaire to fund the development of the mining of Helium 3 before we move to Mars…
As I’ve commented about the need to travel through space faster is needed before we start the big space projects. It sounds as if we will be using Nuclear Thermal Propulsion soon so that within ten years we can get these projects moving faster through space…
I copy all of my comments to; thenewmars.wordpress.com/ for your easy reading…
Wouldn't it make more sense for rotating space stations to use the momentum from the catapulting of space vessels to maintain their rotation or even to assist with station-keeping instead of having to counteract that momentum transfer with the burning of fuel to create yet another momentum transfer?
We need to get the voyager station built that’s an absolute must!
Clever beginning to the video.
Thank you for your work.
United Federation of Planets, here we come!
ISAAC, I just had the weirdest thought (and no, I'm not high). I can actually imagine using your recordings as something soothing, to help an infant go to sleep. Has anyone ever suggested something like that to you? I mean, of course anyone can read nursery stories in a soothing voice, but how many people could have their infant sitting there listening to talking about colonising space?!? I'm an Aspie, so thoughts like that tend to simply cross my mind. Thank you for your wonderful content, as always. Cheers!
He's not the only youtuber who puts me to sleep (no offence Isaac, I don't mean it THAT way) because they have a good voice. I just usually have to edit out the starting and ending music.. :)

Great video! So how soon can we expect all this to occur? I'm guessing not in my lifetime unfortunately. I think I'll be lucky if I make it into space at all! In any case, I'm glad to see that some folks are still seriously considering our prospects as a space-faring community.
Looking at that cis-lunar space map, L3 would be the perfect place to set up solar powered factories. Smelting plant to process all that space ore into building material.
To the point... Er.. the Lagrange point! Try for L4...
Have a good day..
I always wondered if it was a bad idea to remove mass from the moon. A billion large habitats being okay puts it in perspective.
Brilliant as usual mate 👌
the workrate is insane... shout out isaac / jerry / keith
I think Lagrange points push outwards, like antigravity, instead of attracting, like regular gravity... it's a vortex made of 2 gravitational fields opposing each other
There's a Cis-Lunar joke in here somewhere. I hope we can find it!
Authursday!
Elon has mentioned getting 100mt to LEO for $2M USD with Starship. For Kalpana, 100,000 launches would cost $200B USD.
This is where Jeff Bezos, not Elon Musk, has the right idea. Jeff Bezos plans spacesteads in Earth's orbit and colonies on Luna.
Imagine joining an online match and the game places you with a team that's literally on the dark side of the moon.
thank you for answering my Facebook question:)
A potential use for cislunar space are telescopes. (Mentioned briefly) LSST Vera Rubin is going to be super affected by the new satellite constellations being put out by spacex and Amazon. Also we can try terrascopes, David Kipling's very interesting idea.
IF starship gets the cost down anywhere near what they hope then space based telescopes become very real.
"Cost" is a relative term in this context! Should we even be thinking of $ value in a product or should it be a function of manpower to produce the system that produces the system that eventually produces the product?
Obviously we are in a cash economy here on Earth but other models become available and may even be preferable in a post scarcity economy ...... which is what this is creating! We may even get a dualistic model like we see in Star Treak where interactions can be entered into on a monetary basis but general living within the system is cash free!
I think talking about cost is still valid. Even in post-scarcity, you want to discourage certain behaviors (like ordering 1000 hamburgers at once from the replicator). If you use a quota system, then the currency might be quota credits. (Example: I'll give you 2 kJoules of my energy quota if you say "Make it so".)
What the currency IS matters less than the ability to signify value. In a post-scarcity world, influencers might finally get the "exposure" currency to catch on.
Dollars are what we've got. Considering the number of political thinkers who can more easily imagine the end of the world than the end of capitalism...well, it's a cost factor that's easy to research, share, and understand.
There is a $ cost element to set up for sure .... but once you get past 1st generation production it becomes availability rather than cost!
The 10,000 burger order at the replicator could be stopped by peer pressure or even summary execution ... or anything in between! It is a bit like the free chocolate biscuits available for workers to eat in the chocolate biscuit factory. At first they scoff them down but it soon pales and people only take what they want/ need!
Star Trek didn't invent anything. It was only practical execution of ideas already debated on Earth, though I would not mention the name as Americans get diarrhea in the ignorance.
@@timothymclean It shouldn't be surprise, because capitalism is absolutely natural like gravity. Problem are only extreme interpretations if not worship of something what is just simple logic. Even in Star Trek there was a trade between civilizations and local exchange on Earth (mostly handmade goods). It is just that people have guaranteed Social Welfare as resources and production was so cheap, that you didn't need keep competition to keep costs even lover.
Isaac, can we have gravity for long trips by purely accelerating and decelerating during the trip?
Yes, but that takes a lot of fuel, or propulsion tech that we don't have - yet.
@@PGGraham Theoretically, if we have nuclear propulsion, we can accelerate at 1G for the first half of a trip and slow down at 1G for the second half. However, those are short trips of less than 100 light-years. There is a maximum speed for the engine, and once we hit it, are stuck at that speed until we reach the slow-down window.
Realistically probably not, even with a better drive system it isn't very efficient
To moon yes mars Venus Hard interstellar no
Practically speaking, only with a spaceship drive that consumed basically no fuel. Not "perfect conversion of matter to energy" no-fuel, "probably violates conservation of energy and/or momentum" no-fuel.
If fuel is a concern, people are going to point out that you could get superior or equivalent performance from short burns and lots of coasting.
Having learned that the Earth's hill sphere is around 3 000 000 km I thought about connecting orbital rings in a line to make a cooling disk. I estimated that it could easily radiate away 10 000 times the sun light which falls on the earth's surface and thus we could become with this at least 1.4 or 1.3 on the Kardashev scale. One part for cooling and one part for collecting sun light but the interesting part is the cooling function. I estimated 400 W/m² to be radiated away at cozy temperatures.
love the intro music
I have yet to read the NSS report, but I'd like to know what we're going to do with the Van Allen radiation belts if we're going to colonize cislunar space.
To first order, I suppose we are not going to put space colonies in the Van Allen Belts.
Translunar cycler picks up KE through continual Lunar slingshots then transfers this via a 1000 km zipline to suborbital capsules lofted from Earth that then take mag-break rides at 3Gs. You could build 1300 of these for a interplanetary trip at suborbital launch cost every half hour. After a decade's operation this is a mere million humans roaming around Sol system. The same system helps lift cargo from your station on Luna's trailing edge.

Re: Solar sails.
Silver is 5% more reflective than Aluminum and, due to it's high ductility, can be made into a very thin foil.
Also, the moons regolith contains more silver than high grade ores on Earth so it can be sourced and delivered to a ship's in-space construction site cheaply.
Silver should be considered for solar sails as an alternative to Aluminum.
I understand that some people are not wired to pronounce the "R" sound, and I hardly notice it, but what does catch my attention is your pronunciation of the word "volume" as "valume".
I hope my comment isn't rude or annoying.
I love your brilliant work!
Or almost "vallium" ;-)
Still the best intro music!
about that lunar rover swarm prospecting for resources, I can imagine a company that builds and sends the robots to the Moon with telepresence features, then allowing folks on Earth to try their hand at driving the rover around for a cost like a monthly subscription game. Heck, if people find resources the company might allow the finder to keep a portion of the profits and we have minecraft on the Moon (well, all mining, not a lot of crafting)
I wonder how those birds are flying in that rotating station. Artificial gravity by centrifugal force keeps thing on the ground, but without an attachment to the ground, you're in microgravity, right?
True haha
No, there is no magic force that keeps the air from spinning with the structure that encloses it. If a part of the spin axis is in "open air" (contiguous with the air above the "landscape"), then the birds would be in "microgravity" THERE. Below (outward from) the axis, spinning with the enclosed air gives you spin gravity; more the further from the axis. At a moderate distance from the axis, a bird (or a drone or a vehicle) might be able to remain objectively "motionless" by flying anti-spinward against the motion of the internal air. Technically, even at the outer floor, moving anti-spinward relative to the floor reduces your "weight", and moving spinward relative to the floor, increases it, but on a torus or cylinder with a large enough diameter to produce 1 G with 2 or 3 RPM, you'd never notice this effect at walking speed.
This could be the prelude to Bruce Sterling's Schismatrix in his description of the lunar orbital colonies called the Concatenates

@isaac, can you do an episode on the possibility of singular living or artificial entities the size of galaxies or larger(galaxy to local cluster and each step up) eventually reaching the possibility of organic, artifical and/or synthetic creations so large that it's beyond clusters possibly taking up whole voids or even filament and wall sized taking up significant chunks of our know visible universe? Kinda dipping into the lore of marvel comics and trying to assign a physical scale to their manifestation. Thanks!
I feel like the Lagrange point between Mercury and the Sun would be a perfect place for a solar wind collector or other scientific instruments you may want close to the sun.
I was just thinking about colonizing Lagrange points
It seems obvious to me that the first use of space should be cheap renewable energy production to replace fossil fuels.
No such thing as renewable. The future is nuclear. Solar will be more affordable, but it is the waste photon ejection of the sun's fusion core. If we build a space elevator, we could add solar panels the size of a city on it and probably run the nation that it is tethered to, though.
@@NoobNoobNews your thinking a bit too long term on the parameter definition of "renewable" by a couple billion years.
Have you seen Isaac's video on space based solar power generation? If not if highly recommend it
@@allhumansarejusthuman.5776 i know what you are talking about, but at that point it is less about renewable and more about what is cheapest and easiest to run.
You don't need to go to space for cheap energy..
