Ganymede: Ganymede is the largest moon of Jupiter and is known to have significant deposits of various metals, including iron, nickel, and aluminum. Spellcaster Dragons Casting with legendary actions? Plan the mission: Based on the composition of the asteroid, a mining mission can be planned. The estimated cost for a new DM30 II is around $1.5 million. Building a dyson shell around a black hole comes with a plethora of additional and probably intractable problems which need to be solved before even beginning to consider what constitutes a minimum safe distance. In the case of a solid body, the swallowing of mass has a cumulative effect. A: Here are a few examples of human support equipment and their approximate costs: Its worth noting that the specific human support equipment that would be used for a mission to Psyche would depend on the mission requirements and the available technology at the time of the mission. "Our results suggest that for a stellar-mass black hole, even at a low Eddington ratio, the accretion disk could provide hundreds of times more luminosity than a main sequence star.". The energy doesn't have to be visible radiation - it can be anything output by the enclosed object.. You don't want the elements of your swarm colliding with the accretion disk, so they will need to orbit well clear of it, much farther out than the minimum orbital radius. But Wright suggests it might be exceedingly difficult. I wanted to see how efficiently chatGPT harnesses information from the internet to give me specifics and how well its large language model (LLM) of computation understood what I was saying. That we do not see them because managed BHs are the optimum places for high computation civilizations. One example of a PEM fuel cell that could be used for this application is the Ballard FCgen-H2PM fuel cell. I must say I am enormously impressed. George Dvorsky has advocated the use of self-replicating robots to overcome this limitation in the relatively near term. Unexpected results of `texdef` with command defined in "book.cls". A: There are currently no mining robots specifically designed for mining metals on Psyche, as no such mission has yet been undertaken. Because who have not tried to enter the Black Hole? [8], SETI has looked for such infrared-heavy spectra from solar analogs, as has Fermilab. Scientists have upped the ante on theoretical Dyson Spheres with a proposal for alien civilizations constructing the colossal megastructures around stellar mass black holes, pushing the energy harvesting power well beyond what could be possible with just a traditional Dyson Sphere. Q: Ok, now add up all these costs and give me an approximate number. I asked AI engine chatGPT to build me a hypothetical 2 meter thick Dyson sphere at a distance of 2 AU (~300 million kilometers). Determine composition: Once a suitable asteroid has been identified, its composition needs to be determined. We would need to consider other sources of material, such as mining other planets or moons in the solar system, or developing new methods for obtaining and processing materials. Some way of starting a new system with your upgrades. Q: Give me a list of equipment needed to mine all the metal on Psyche. If their maximum attainable velocity is one-half lightspeed, the dyson swarm units will be able to boost away from orbit around the back hole, if they need to (just think of it as an additional safety feature). A Dyson sphere is a theoretical megastructure that surrounds a star to collect its energy output. Q: At current world GDP growth rates, how long would it take for world GDP to reach $6.117 x 10^33? The accretion disk is pretty hot. Put someone on the same pedestal as another. John (He/Him) is the Components Editor here at TechRadar and he is also a programmer, gamer, activist, and Brooklyn College alum currently living in Brooklyn, NY. Tungsten: Tungsten is a very hard and dense metal that could be used in the construction of the Dyson spheres high-temperature components, such as lighting filaments and electrical contacts. It would produce far more energy than even a normal Dyson Sphere. The second outlines impossibly dense regions of space and time surrounded by boundaries that separate their interiors from the rest of the cosmos. Asking for help, clarification, or responding to other answers. $\begingroup$ Building a Dyson sphere is about capturing energy output and using that to power to run the civilisation inhabiting the sphere. Dyson spheres all tie back to a system called the Kardashev scale, which is based on how much energy a civilization consumes. If such a megastructure could be constructed, it would significantly diminish the life of the star from our perspective, but would be lit up like Christmas lights in infrared. This makes sense as a way to predict movement, create stability, and easily adjust or work on any individual unit in the Dyson swarm. This would include satellite communication systems, GPS, and other navigation tools. [24], Dyson spheres appear as a background element in many works of fiction, including the 1964 novel The Wanderer by Fritz Leiber where aliens enclose multiple stars in this way. What is the difference between these 2 index setups? A large dyson sphere encircling a neutron star at the high end of the mass spectrum will bend light differently to a black hole. I suppose I should ask, but it's psychology not physics, why would a society that can build a DS be worried about other people/aliens noticing them:) A managed accretion disc would end your energy worries for a long time, hadn't thought of that aspect. Black Hole 0.185 22900 1240 22 0.09590235397 O-type 2.165 22900 1240 257 We now know that an actual sphere would be unstable; it would crash into the star. it would have been funnier if you get close, and the gravity is so strong you cannot fight it, get sucked in and it says, "Game Over. These robots would need to be able to operate in the low-gravity environment of the asteroid and withstand the extreme temperatures and radiation levels. Q: Provide an estimate of the total amount of material we could get from completely mining all the asteroids in the solar system and also Io, Callisto, Ganymede, Europa and Mercury. It only takes a minute to sign up. Taking the natural logarithm of both sides, we get: n x ln(1 + 0.025) = ln(($6.117 x 10^33) / ($85 trillion)), n = ln(($6.117 x 10^33) / ($85 trillion)) / ln(1 + 0.025). "In this paper, we consider and discuss six types of energy sources: the CMB, the Hawking radiation, an accretion disk, Bondi accretion, a corona, and the relativistic jets from two types of black holes: a non-rotating black hole and a rotating black hole," the researchers explain. Things that will actually happen in our time and are not added to the game, at least not to my awareness. Then when you drop it into a black hole, all this is taken to extremis. Nothing with structural strength high enough exists, and it would require continual adjustment to not fall into the star/black hole. Would accretion discs and the massive gravity well pulling in everything around you not be a worry, in the future? Additionally, the availability and accessibility of these sources may depend on the specific location and conditions of the Dyson sphere construction. [20], Stellar engines are hypothetical megastructures whose purpose is to extract useful energy from a star, sometimes for specific purposes.

Solar panels are more effective on planets close the sun while swarms are more effective if the sun has high luminosity. But by analyzing what such an object would look like and leave behind as excess heat, scientists are better able to search the cosmos for that signatureand find any new neighbors who are running Dyson spheres on their nearest black hole. Towing them around does require a rather large-scale propulsion system, though. Withdrawing a paper after acceptance modulo revisions? If you like what we do, please consider making a donation. Worldbuilding Stack Exchange is a question and answer site for writers/artists using science, geography and culture to construct imaginary worlds and settings. : You cant pull energy out of a black hole, its physically imposible, just like you cant travel in time. @Len - other way around. But, the galaxy is an immense place with an estimated 400 billion stars in it. Q: Ok, now lets see a few examples of relevant communication and navigation equipment and their approximate costs. For the uninitiated, prolific scholar Freeman Dyson first described his namesake Dyson sphere concept in a landmark 1960 paper. It is believed to contain water, carbon, and other minerals that could be valuable for space exploration and construction. Identify asteroids: The first step in asteroid mining is to identify suitable asteroids. The number of craft required to obtain, transmit, and maintain a complete Dyson sphere exceeds present-day industrial capabilities. Determine the optimal distance from the sun at which to place the Dyson sphere. It uses a rotary-percussive drilling method and can drill up to one meter deep.

Scientists have upped the ante on theoretical Dyson Spheres with a proposal for alien civilizations constructing the colossal megastructures around stellar mass black New York, The estimated cost for a new 797F is around $5 million. Something's wrong. Could you build a stable structure just short of the Schwarzschild radius or would you need to move farther back to be safe? To absorb the accretion disc luminosity, a Dyson ring or a Dyson Swarm could be a Iron Iron is a common construction material due to its strength, durability, and abundance. Wow this is really cool! I flew into one, well as best as I could, it didn't do anything. No, I don't think so. It could be used for the framework and support structure of the Dyson sphere. This is actually a rather efficient way of producing energy, since it can turn up to 40% of the rest mass of matter in the disk into radiation, much better than nuclear fission or fusion. or at least your mech upgrades. We can start with the Dyson Sphere. RASSOR: The Regolith Advanced Surface Systems Operations Robot (RASSOR) is a mining robot designed for use on the Moon and other planetary bodies. Additionally, the cost would depend on the specific design and capabilities of the storage and transportation equipment required for the mission. The estimated cost for the Scarab project is around $1 million. [6] In 2013 Dyson said that he had come to regret that the concept had been named after him. Imagine doing it by mistake first time. While predominantly focused on the radio signals produced by an alien civilization, the problem becomes what happens if an alien civilization is not broadcasting them for reasons of self-preservation (i.e., you can't come and invade what you don't is there). WebThe innermost Dyson sphere of the Matrioshka brain would draw energy directly from the star it surrounds and give off large amounts of waste heat while computing at a high temperature. Iron: Iron is one of the most abundant metals in the universe and could be used in the construction of the Dyson spheres structural components. Q: Ok, now lets see a few examples of human support equipment equipment and their approximate costs. Once the equipment arrived at Psyche, it would need to be carefully deployed and assembled on the asteroids surface or in orbit around the asteroid, depending on the specific mining plan. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Include specific examples of spacesuits, life support equipment and medical equipment. In "San Junipero," two young women meet and fall in love from inside a server farm, while their bodies exist in vegetative states in the real world. From this you can calculate that, at 2.75 K, the emitted power of a black body is about 3.2 $\mu$W /$m^2$. The second outlines impossibly dense regions of space and time surrounded by that...
