  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.

  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.

  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.

Also nothing stops someone at your destination from shooting at you before you get there. If it is colonisation/exploration vessel then it does not matter, but pusher plate is both smaller target (as if this make a difference in place called space) and more durable overall. Besides, armouring nose of spacecraft is most optimal, so having vulnerable propulsion at this nose would basically guarantee lose of maneuverability in any kind of fight.

  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.

  Nukes are significantly less threatening without an atmosphere (or other medium) to carry a blastwave and space provides a near infinite amount of, well, space to put between you and the detonation point. Enough distance between an object and the blast and all that terrific thermal energy will be spread out enough it can't even singe paint. Most medusa drive concepts are using sub kiloton propulsion units with kilometers of separation between ship, bomb, and sail, but there's nothing that would prevent you from powering it with 50 megaton Tsar Bombs or even gigaton nukes, you'd just need to scale up the distance between components until safe and the size of sail to still catch enough energy for appreciable thrust.

  @StacheMan269 сағат бұрын

  Technically yes, but a device of such low energy would be less of a bomb and more of a firecracker and you'd have to detonate a truly ridiculous number of them rapid fire to get anywhere fast. Practically though, that's barely even a concern with a medusa drive which has tens to hundreds or maybe more kilometers of tether in open space and spooled on its winches with which to turn the sharp pulse imparted on its sail into a gentle, even pull on the main hull.

• 
  @st3venseagal2485 сағат бұрын

  This is one of my favorite design concepts because it directly challenges that problem. You can reduce the g-force on the ship by allowing the ship to also move along the tether. So when they detonate a bomb the ship can slip backward on the tether at a slower rate of acceleration than the sail and tether itself.

  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.

  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.

  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.
