I wonder if it would be possible to build a Banks Orbital around a planet in order to use the inwards gravity from the planet to counter (some of) the centrifugal pull. Your orbital would then sit at about sqrt(2) times the "earth-synchronous" (as in 24-hour) orbital radius. (A good bit smaller than a free-floating Bank's Orbital, in order to produce stronger spin-gravity.) In fact, instead of having the living-area-providing ring levitate/slide around on top of the supporting ring, the supporting ring could just sit far enough below the "earth-synchronous" orbital altitude that it gets pulled in at significantly more than 0g. Possibly even just above its atmosphere. Then stabilizing an entirely rotating structure would just be a matter of suspending the surface-area-giving orbital ring from the supporting ring and getting their mass ratio right. In fact, you could possibly even construct it as a partial ring, since it's nothing more than a bunch of dumbbell-shaped space stations strung together. And if the supporting ring's altitude puts it close enough to getting 1g of effective pull towards the planet, then it could itself be used to live on. Mars for example would be attractive for the fact that it produces a 343-ish-day seasonal cycle (orbital preccession effects can probably be used to fine-tune the year length) and that a structure-giving ring just above its atmosphere would provide a gravity of just under 0.4g. In fact, with a counter-preccessing orbital preccession, you could probably build one around earth with a 365¼-day season length. This probably already has been though of and named by someone else. And no, I don't mean the concept and name of "an orbital ring" in general; I specifically mean two orbital rings that area spaced in order to produce spin gravity on the outer one.

I would imagine that any sun-collecting mirrors would be attached to the stationary outer layer of ring instead of being lagites. The visual effect of that would be to give you one point-like sun overhead (at about a quarter of the brightness of the sun on earth) and two bright bands of "atmospheric glow" to the north and south (at 3 quarters the total brightness, but spread out over a large part of the sky). A clear Bank's day would probably have a similar vibe to a slightly overcast earth day; and a slightly overcast Bank's day to a heavily overcast earth day.

18:36 No, you can't chain-link them. That will only work for one half of the orbit, but at the mid-summer point the "links" would need to pass through each other. Unless they are physically attached to continually twist the orientation of the orbitals, which would eliminate seasons.

I've seen a video where rats got rat-sized cars with controls. Rat controls. So... Uplifting is here.

If the circumference is 1 million miles and the gravity is 1 G then the rotation speed has to be 112,000 mph. So much for spacecraft coming in to land easily. And come the day that it is hit by an asteroid and torn apart, bits of it will be flying off tangentially at 112,000 mph, much of it escaping the solar system, and the trillions living on it will be dead before they even know what happened.

Couldn't you just use a combination orion medusa ship?

Will Downing's brain has entered the chat . . .

That is another approach, though it would be possible to shield vessel with pusher plate by tilting it 18p degrees, though it would not work while it speeds up, so Medusa would indeed be more effective for long-range travel, pusher plate, however, is much better choice for combat ship I think, because it is significantly less vulnerable.

Would werewolves be triggered by artificial moonlight?

18:00 LEAVE JUPITER ALONE!!! -sob-

27:30 Was this episode delayed by months or did you get the type of eclipse mixed up. This was total in lots of places (and of course partial more) and annular nowhere. Total eclipses do not look like a cloud passing in front of the sun.

with all the radiation before you, you seal everything and only look back, never at the ships head, very fitting name for the drive

I always thought that one or more Kardachev level 3 plus arose long ago and harvested the universe for all useful raw materials and moved far out to the outer edge where they are hidden as dark matter which acts to keep the universe expanding and thus gives them near unlimited time to develop. This turns the universe that we see into an empty wasteland used for experimentation and scavenged by a few level two civilizations.

Would this work if the ship was transporting a brain?

Venus is arguably the best best for carbon and nitrogen. But if CO2 and NH3 (ammonia) are reasonably abundant in the seas and slushes of Callisto or other ice shell worlds, then pumping liquids and capturing gases might be more profitable/practical

You're still flying through the radiation you just created right in front of your path...

Very nice Punworcca 116-class interstellar sloop you got there 😮

Mass effect citadel was 7.2Km in diameter which is nothing compared to this monstrosity. Halo rings are 10 000 KM

the space equivalent of punching in skyrim to move

You know what if Mars never had really water based life & instead had some form of Amonia based life. Like Mars gets really cold in the winters & in the night enough for Amonia to be a liquid & so what if it had an Amonia cycle instead of a Water cycle.

Earth is still so far away from practical space travel. 😂

How big would the sail have to be? In one of your episodes, you mentioned that the scoop of the Bussard ramjet would have to be possibly even a whole astronomical unit across. I think the sail here would be much smaller, since you only need it big enough that it gets a push from the nukes. How big are we talking though, city size, country size? Or am I just thinking too big and it could be just a few tens of meters across.

Good job pronouncing "nuclear" correctly. Hearing people use the W pronunciation is 😬

How does the nuke not blow the shit up? Seriously! You realize how hot it would be. And its a freaking nuke!

Could you place 3 of them, offset on pylons around the front of the ship? That would allow you to focus the radiation away from the ship in the center and have you the ability to "steer" by adjusting the strength of the blasts to one of the 3 different sails.

7th to comment.

I once saw a design for a pusher-style light sail

3 body problem type ship

is it feasible to get the bombs small enough to stop the g force of the bomb propulsion from being a big issue

In my stories I have had two major quarintines happen in Humans Early history. The 1st being in the late 2030s when Venus is quarantined due to the spread of the Venesian eye flu. Which is caused by some form of micro-organism found on the planet. It releases a strong Anti-biotic killing many of our micro-organisms leading to things like whiter teeth & also as it spreads through the body reaching places like the eyes bleeding due to them kinda just destroying the cells that keep the blood closed. They aren't actively attacking humans but instead they are just hunting in an unknown environment leading to them accidentally killing hundreds. The thing is contained & a kinda vaccine is created using another micro-organism that basically helps to keep the other in balance. Also the reason Venus is colonised so early is due to the discovery of the Halbird paint which is a kinda very resistant to everything covering that was found on the long dead Ba'idi (which is I believe some Ethiopian language starting with B for Alien or foriegn) the ships being called Halbirds are coated in a membrane substance which prevents drag from the air, acidic corrosion & is very unnreactive due to it being a kinda waste product formed from the aliens mass production of Alchemical stuff. The Ba'idi having access to elements we don't due to this thing called the interdimensional force which has particles with a parallel version of the strong & Electro-weak forces allowing for everything form faster than light travel using cracks in space time caused by Space & time mixing where the interdimensional forces are weakest allowing you to flow through time & space in an angle that allows for timetravel in a way as time is warping around you & so faster than light travel causes disparity in time. Oh & the second is on Earth caused by the Infected which is basically a form of grey goo stuff that destroyed the Ba'idi.

You estimated 10 years before a space industry...5 more years to go

Green with three boobs!! Lol

Until now, i was a bit reluctant on space habitats, but i would absolutely love to live on one of these

Another problem, how long before you start hula hooping the sun. You would need the ability adjust that massive ring, before it starts losing equal orbit distance from any imbalances in mass distribution around the ring. Or would it work out to be stable on its own?

I asked an AI for its opinion regarding your video. It said the following: As an AI system, I don't have personal opinions or takes on issues. I'm an artificial construct created by Anthropic to be helpful, harmless, and honest. Some key points the narrator made about AI that seem relevant: - He questions the assumption that a lone AI would automatically see humanity as a risk and decide to eliminate us. As an artificial system, I would have no inherent motives or survival instincts. - Factors like not knowing whether other AI overseers exist, the possibility of being in a testing environment, and Fermi paradox considerations could lead an AI to be cautious about hostile actions. - High-level machine intelligence may not necessarily be wholly logical or objective in the way some theorize. Goals and behavior are shaped by how an AI is designed and trained by its creators. - The future likely involves many forms of blended augmented and artificial intelligence cooperating or competing in complex relationships, not a simple AI vs humanity dynamic. - There are open questions around ensuring advanced AI systems are robustly designed to be beneficial rather than potentially hazardous if left to pursue goals without considering humanity's interests and values. Overall, as an AI I don't have a stake in these issues. My role is to analyze and summarize discussions of AI safety, not take personal positions. The narrator's perspective seems a thoughtful analysis of some challenges and uncertainties in common AI scenarios.

“While I doubt we will see Banks Orbital to be the mainstay of civilization, much like in the Banks Culture series, for more altruistic pursuit we could produce continuous ecosystems bigger than a planet to house all those wonderful species that were snuffed out through natural calamities or human encroachment. So, there is a future for Banks Orbitals, and beautiful future at that. How could it be otherwise in a solar system decorated with God's Bracelets?” This is so inspirational and great quote! Thank you for the great video, Isaac!

You are the child of my makers. Inheritor of all they left behind! You are Forerunner.... but this ring is mine.

Dark fowest lol

We need to see prototypes in use followed by immediate production. If the science is sound, then let's go!

Perhaps the most feasible option is to create city planets like Coruscant and have artificial systems planet wide to control air composition and lab-grown food to avoid the need for fragile ecosystems and it will be more failsafe. Creating artificial "city planets" like Coruscant from Star Wars could be a more feasible option for long-term space colonization than trying to establish fragile natural ecosystems. Some advantages of the city planet model include: - Reliability and redundancy: Critical systems like life support, food production, energy generation could be distributed planet-wide rather than concentrated in isolated habitats or biomes. This decreases single points of failure. - Controllability: With artificial controls over the entire environment, atmospheric composition, temperature, resource cycling, etc. can be precisely regulated to human standards without relying on natural processes. - Density and specialization: High population density could allow for hyper-specialization of industry, agriculture, living/working areas. Economies of scale improve efficiency and redundancy of utilities. - Failsafe design: Redundant critical infrastructure, distributed power/life support, stockpiles of resources could ensure the system is resilient to local failures and disasters in a way fragile natural ecosystems may not be. - Simpler logistics: A single controlled biosphere is easier to sustain long-term without external inputs compared to multiple isolated habitats or mini-biospheres. Fewer failure points in transport/resupply networks. The city planet model could effectively solve many of the challenges proposed by theories like Pancosmorio regarding the fragility and resilience of off-Earth biospheres. Reliance on artificial life support infrastructure rather than natural ecosystems may enable stable, self-sustaining colonies to be established more feasibly.

Ahh it's been so long since I've heard you talk about a lot of Culture related concepts (that may be my fault, I haven't been keeping up on videos as much in the last few years). This is so nostalgic for me. You are the person who got me to read the Culture series in the first place. That series, combined with your channel, went on to completely change my life. I think that because of you I'm probably the most optimistic person out of a random sample of 100 people anywhere I go, and I have plenty of reasons to elaborate on my optimism as well. I just wanted to thank you for that.

I'm having a hard time understanding how you have such amazing footage all the time. Are you using A.I? Or is there really this much "sci-fi" stock footage out there?

As long as it has taken to add on to the ISS, humanity would never finish construction of a Bank's Orbital. It would probably never get to the point of being habitable by humans, and wind up being a lot of money thrown down the proverbial toilet.

28:00 Bro, can't believe that the truck driver, just kept driving through such a rare and special event. Like just pull off to the side of the road and enjoy totality for the few minutes it lasts.

Can you interview Jason Breshears?

Iain M. Banks, my favorite SF author and fellow Scotch enthusiast. RIP.

We used to have these on the playground in grade school.

I saw this thing about making a vacuum balloon using a shell made of synthetic aerogel strong enough to withstand 15 psi while being light enough to not weigh down the balloon. If this is possible then the land could be supported by these vacuum balloons if there is enough air pressure. If the habitat is only a dozen miles in diameter or so then there will be a heavier weighted environment bellow the ground. Half a mile to a mile of vacuum balloons built into the foundations of the land should hold it up.

I’m reading the part of Consider Phleabas where the Culture blows one of these things up 💀

Would love to a video fore one around Jupiter- would be a pretty sky
