If that is close enough to "insignificant", there is no need to go further. Can we create two different filesystems on a single partition. In the longer term, consider the concept of uploading people's consciousnesses to some kind of data storage center, as proposed in an episode of the dystopian anthology series Black Mirror. Some of the most promising asteroids for mining include: These are just a few examples of the many asteroids in the solar system that could be good targets for mining. Okay, so we have our two super freaky ideas. 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. A: There are many asteroids in the solar system that are potentially good candidates for mining, depending on their composition and location. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. I must say I am enormously impressed. Since this is about 400,000 times the radius of the solar system (using the aphelion of Pluto as the marker - forget the Oort cloud for now), this suggests a pretty heroic structure, even by Dyson Sphere standards, and causes one to wonder exactly where the materials will come from. However, its important to note that this is a very rough estimate and should not be taken as an accurate cost calculation. The best answers are voted up and rise to the top, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. How, then, could this civilization harvest the energy? That part requires thinking beyond just the Dyson sphere and expanding to a Dyson swarm or bubble. Additionally, the cost would depend on the specific design and capabilities of the power generation equipment required for the mission. Since it is surrounded by CMB with an effective temperature of 2.75 K, it will reach an equilibrium temperature of 2.75 K. That's what thermal equilibrium means for a black body. Based on the estimates I provided, the total cost would be in the range of: So the total cost of all the materials would be in the range of several quadrillion dollars to several septillion dollars. If we could disassemble both Jupiter and Mercury and also mine metal-rich asteroids and the major metal-rich moons of Jupiter and Saturn, we would get least 10^27 kilograms of material would be more than enough to build this sphere. In the most literal way, we'd have to harvest energy from not only the sun, but from Jupiter (which is almost a star, itself) and everything else available to us in our solar system. Solar panels: Solar panels are a common source of power for remote operations. Extract the metals: There are several methods that could be used to extract metals from asteroids, including drilling, blasting, and crushing. Hsiao and his collaborators from the Institute of Astronomy in Taiwan, brings us to the very edge of possibility itself. Some of the metals that could be mined from asteroids for this purpose include: Overall, asteroid mining could provide a valuable source of metals for the construction of a Dyson sphere, and ongoing research and development in this field could help to make this a more feasible and cost-effective option in the future. A: Here are a few examples of metal refining equipment that could potentially be used for refining metals on Psyche, along with their estimated costs: Its worth noting that the cost of metal refining equipment for use on Psyche would likely be much higher than the above estimates, as the equipment would need to be specially designed and built to operate in the unique environment of an asteroid. The estimated cost of a robotic arm ranges from $1 million to $5 million, depending on the capabilities. Not so (in any meaningful way) for the energy which is constantly being generated by the civilization which operates the DS. ($10,00 quadrillion for Psyche sounded attractive, so I focused on Psyche). The next major revision was designed by S. Abbas Raza, building upon the earlier look, and coded byDumky de Wildein 2013. Accretion disks also routinely produce high-energy beams, or jets, of plasma that rocket away from the disk and the Black Hole at velocities close to the speed of light. Visual Q: Ok, now add up all these costs and give me an approximate number. All rights reserved. KelvinPlanck statement and entropy derivation. New York, Thermodynamically possible to hide a Dyson sphere? Search for Extra Terrestrial Intelligence (SETI), the world's billionaires venture outside of our planet, Your Privacy Choices: Opt Out of Sale/Targeted Ads, Extraterrestrials could use Dyson spheres to harvest. Callisto: Callisto is another moon of Jupiter and is thought to have a rocky, icy surface. A black hole will turn anything you throw into it to maximum entropy so it shouldn't be surprising that you can get energy by dropping things in. Install a network of mirrors and other devices to focus and redirect the suns energy towards the inhabited areas of the Dyson sphere. It has a drilling depth of up to 45 feet and a hole diameter of up to 12.25 inches. Q: Ok, now lets see a few examples of relevant communication and navigation equipment and their approximate costs. Dyson spheres have not been detected yet, but an advanced alien civilization would surely need them. [20], Stellar engines are hypothetical megastructures whose purpose is to extract useful energy from a star, sometimes for specific purposes. [2][3] Variations on the concept include a single circular band in Larry Niven's 1970 novel Ringworld,[3][26][27] a half sphere in the 2012 novel Bowl of Heaven by Gregory Benford and Niven,[2][3] and nested spheresalso known as a Matrioshka brain in Colin Kapp's 1980s Cageworld series and Brian Stableford's 19791990 Asgard trilogy.[1][3]. Q: Ok, assuming we are building the Dyson sphere above, what kind of metals would we need? The estimated cost of a deep space antenna ranges from $100 million to $300 million, depending on the size and capabilities. I think Dirk has a valid point, but +1 for rigor and effort and a fun read. It has a drilling depth of up to 1,000 meters and a hole diameter of up to 5 inches. The mission would involve sending a spacecraft to the asteroid to extract the desired metals. Hearst Magazine Media, Inc. All Rights Reserved. While the hot material stays beyond the singularitys event horizon, it can emit energy that radiates away into space. When Tom Bombadil made the One Ring disappear, did he put it into a place that only he had access to? Additionally, a mission to Psyche would likely require additional equipment for radiation shielding and protection from other hazards of deep space travel. Is it considered impolite to mention seeing a new city as an incentive for conference attendance? Tungsten Tungsten is a dense and heat-resistant metal that could be used for constructing the supports and wiring of the Dyson spheres energy transmission system. Identify asteroids: The first step in asteroid mining is to identify suitable asteroids. In the new paper, published earlier this summer in the Monthly Notices of the Royal Astronomical Society, the researchers ponder what it would take to power a type 2 or type 3 civilization, whose energy needs consume their entire solar system: How could Earth become a type 2 civilization? How challenging? NASAs RASSOR (Regolith Advanced Surface Systems Operations Robot) is a lunar mining robot that was developed to excavate and transport lunar regolith. For a Dyson sphere thats at 2 AU and 2 meters thick, how many asteroids would we need to completely mine? Now, the NTHU researchers have figured that capturing the energy of a stellar mass black hole could provide as much as five times the amount of energy captured by a main sequence star, and might even be more visible as a result even using current telescopes. This makes sense as a way to predict movement, create stability, and easily adjust or work on any individual unit in the Dyson swarm. [21][22], A precursor to the concept of Dyson spheres was featured in the 1937 novel Star Maker by Olaf Stapledon,[1] in which he described "every solar system surrounded by a gauze of light-traps, which focused the escaping solar energy for intelligent use". or at least your mech upgrades. A: Asteroid mining is a potential source of various metals that could be used for building a Dyson sphere around the solar system. That problem was what inspired physicists Freeman Dyson to postulate in 1960 that a sufficiently advanced alien race would reach the point where its energy needs exceeded what its planet was capable of supplying. How much material would I need to build this Dyson sphere? Is a copyright claim diminished by an owner's refusal to publish? Protect a planet against a black hole attack. Therefore, it is likely that mining all known asteroids and the metal-rich moons of Jupiter and Saturn, as well as completely disassembling Jupiter and Mercury, would provide enough material to construct a Dyson sphere that is 1 m thick, 1 AU from the sun, and has a composition of 50% silicon, 30% carbon, and 20% metals. But is it at all feasible to use a black hole as you'd harness the energy of the sun or another star? If you want to understand what the Universe is, how it began, evolved, and will eventually end, astrophysics is the only way to go. Then when you drop it into a black hole, all this is taken to extremis. A: You are correct, I apologize for the mistake in my previous response. At current world GDP growth rates and assuming current prices, it would take about 600 years for us to have enough capital to build the sphere. And what Winterberg is saying is that something's got to give, like the wave nature of matter. can one turn left and right at a red light with dual lane turns? I think it's essentially correct. The issue seems almost well consigned to science fiction, but it is an important one when talking about the search for extraterrestrial intelligence (SETI). If you truly want to understand modern astrophysics, knowing how to read this graph is essential. As for how your managed BH Dyson sphere might fare, have you ever seen a Chinese lantern catch fire? Communication and navigation equipment: To coordinate the mining operation and ensure the safety of the mining robots and personnel, communication and navigation equipment would be needed. Give me some details on the kind of rocket or launch vehicle that would work. This distance would need to be far enough away to avoid the intense heat and radiation of the sun, but close enough to capture a significant amount of its energy. Silicon, carbon, and metals are likely to be among the most commonly used materials. How can I drop 15 V down to 3.7 V to drive a motor? Scientists have upped the ante on theoretical Dyson Spheres with a proposal for alien civilizations constructing the colossal megastructures around stellar mass black Therefore, it's a theoretical device that sits around an entire star and harvests its energy. [5], Dyson did not detail how such a system could be constructed, simply referring to it in the paper as a 'shell' or 'biosphere'. Keeping space fairly clear of debris in the area. All that said, even though we imagine black holes as energy sinks rather than generators, that is not entirely the case. Building a Dyson Sphere around any star requires very advanced capacities. Spellcaster Dragons Casting with legendary actions? Estimates suggest that Mercurys crust may contain around 10^20 kilograms of metal, including significant amounts of iron and aluminum. Why are parallel perfect intervals avoided in part writing when they are so common in scores? A black hole Dyson Sphere would be the mark of a Type III civilization one with the capacity to collect the energy equivalent of an entire galaxy. It could be used for constructing the solar panels and for other parts of the Dyson sphere that require light, yet strong materials. The calculation includes a number of approximations, but 600 years is a very short period of time based on astronomical and even civilizational timescales. This, it turns out, is pretty easy to answer as we speed into the 2020s and beyond. It uses a rotary-percussive drilling method and can drill up to 50 meters deep. Q: What if we include Jupiter and Mercury and completely disassemble them? A: Unfortunately, I cannot provide an accurate cost estimate for such a large amount of material, as the prices of these materials can vary greatly depending on many factors such as supply and demand, location, purity, and form. How small stars help with planet formation, Mike Sipser and Wikipedia seem to disagree on Chomsky's normal form. Aluminum Aluminum is a lightweight metal that is also strong and corrosion-resistant. Under the right conditions, the matters self-gravity overwhelms everything else, leading it to collapse into what we call a singularity where all the mass gathers in a single geometric point. That we do not see them because managed BHs are the optimum places for high computation civilizations. So the efficiency $\eta$ of the BH as an energy absorber is $$\eta = \frac{A'}{\frac{A}{2}} = \frac{1.1 \times 10^8}{.6\times 10^{32}} = 2\times 10^{-24}$$. In this way, a single black hole Dyson Sphere could put the beings that built it on a path to becoming a Type III civilization one with the capacity to collect the energy equivalent of an entire galaxy. What metals could best be mined from asteroids for our purpose? Alternative ways to code something like a table within a table? The energy doesn't have The main use of building a Dyson swarm around a black hole would be to capture the energy released by its accretion disk. Dyson shell is (unfortunately) impossible to build. However, its important to note that these estimates are highly uncertain and based on limited data, and the actual amounts of material available could be significantly different. So, it's easy to see how much energy this electronic infrastructure alone would take up, let alone the heat sink and cooling to make sure all of the electronics can run safely and sustainably. Orbits near a black hole are strange and dont follow Keplers laws, and things are more interesting with rotating BHs. Nothing with structural strength high enough exists, and it would require continual adjustment to not fall into the star/black hole. Gold: Gold is a highly conductive and corrosion-resistant metal that could be used in the construction of the Dyson spheres electrical components. You probably think of a Dyson sphere as a structure that captures the sun's energy, but what would happen if you built one around a black hole instead? Further out, it will be much simpler and easier, but require more materials" Notes: Never inhabited due to launch or on-orbit failure, Part of the, Feasibility and science-based speculation, Science Fact and Science Fiction: An Encyclopedia, "Search for Artificial Stellar Sources of Infrared Radiation", "STARSHIP CENTURY SYMPOSIUM, MAY 21 - 22, 2013", On the Inevitability and the Possible Structures of Supercivilizations, "When Will We Find the Extraterrestrials? Atlas Copcos DM30 II is a large rotary drill rig used in surface mining operations. Psyche: Psyche is an asteroid located in the asteroid belt that is believed to be made almost entirely of metal, including iron, nickel, and gold. This makes me wonder: If the black holes in other galaxies were covered in dyson spheres Could we detect that currently? Espaol - Latinoamrica (Spanish - Latin America), https://www.youtube.com/watch?v=ulCdoCfw-bY, https://journals.aps.org/prd/abstract/10.1103/PhysRevD.103.023014. Fictional depictions often describe a solid shell of matter enclosing a star an arrangement considered by Dyson himself to be implausible. Specifically, a sphere with the diame Continue Reading Since a blackbody radiates uniformly in all directions, the fraction of the energy emitted by any portion of the DS intercepted by the BH will simply be the BH area divided by half the area of DS. Assemble the raw materials into larger components of the Dyson sphere, such as individual panels or segments. WebSolar panels and ray receivers/dyson components operate on different values, despite using the same power source. Estimates suggest that Europas surface may contain around 10^17 kilograms of water ice, as well as significant amounts of other volatiles such as carbon dioxide and sulfur dioxide. The estimated cost of solar panels ranges from $0.30 to $0.50 per watt, depending on the type and efficiency of the panel.
