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 obviously involves some pretty extreme astronomical engineering. Its design could potentially be adapted for use on Psyche to mine and collect metal samples. If you're a Type II civilization, you'd get far more bang from your investment building a Dyson Sphere around a black hole than a typical main sequence star. Q: Would 4 x 10^20 kilograms of material be enough to construct a Dyson sphere that is 2 m thick, 2 AU from the sun and is 50% silicon, 30% carbon and 20% metals? : You cant pull energy out of a black hole, its physically imposible, just like you cant travel in time. Only at the event horizon, the coordinate speed of light is zero, and the pencil is supposedly falling 299,792,458 m/s faster than that. Keeping space fairly clear of debris in the area. On the other hand, pairs of particles, one particle and one antiparticle, separate due to the strong gravitational field whereby one gets inside the event horizon, and the other is emitted as radiation. That'd be a very interesting feature to be included. Additionally, a mission to Psyche would likely require additional equipment for radiation shielding and protection from other hazards of deep space travel. 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. Ceres: Ceres is a dwarf planet located in the asteroid belt between Mars and Jupiter. We Know How Fast Earth Spins Dont We? Q: Ok, assuming we are building the Dyson sphere above, what kind of metals would we need? Medical equipment: Medical equipment for space missions needs to be lightweight, compact, and able to operate in microgravity. NOTE: This answer has limited itself to considering a possible minimum safe distance for a dyson swarm and not a dyson shell. 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. The power density emitted by the surface of the sphere will be twice that of the CBE, which will produce an apparent temperature of 3.27 K, or about 0.5 K above CBE. 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. Honestly. A: Assuming a constant annual GDP growth rate of 2.5%, we can use the formula: where FV is the future value (i.e., $6.117 x 10^33), PV is the present value (i.e., the current world GDP, which is approximately $85 trillion), r is the annual growth rate (i.e., 2.5% expressed as a decimal, or 0.025), and n is the number of years. So really, the considerations are the size of the hole, being able to safely capture and distribute the power output, dealing with gravitational extremes, etc. If a strong enough material is used, an alien civilization could potentially tame a black hole, feeding it matter to produce energy and harness its force. Q: What are some specific examples of drilling and mining robots that we can use? What are major sources of these materials in the solar system? About one one-billionth of the Suns total energy output actually reaches the Earth. 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. Additionally, the cost would depend on the specific design and capabilities of the drilling equipment required for the mission. This makes sense as a way to predict movement, create stability, and easily adjust or work on any individual unit in the Dyson swarm. Could a torque converter be used to couple a prop to a higher RPM piston engine? Click to load last save.". That is, if power is radiated uniformly in all directions, the power level produced by any point on the surface at the center will be the same as if the surface point were at the center radiating outwards to the surface. Nickel Nickel is a durable and heat-resistant metal that could be used for constructing parts of the Dyson sphere that will be exposed to high temperatures, such as the inner layers of the sphere. The best answers are voted up and rise to the top, Not the answer you're looking for? This difference in speeds is precisely that referred to above by ceiling and floor observers. Quasars (opens in new tab), which are pretty much the energy being released in the immediate area around a supermassive black hole in the center of a galaxy, are the brightest objects in space, outshining all of the stars in the galaxy that contains them itself. A Type III civilization could combine them. Q: Ok, now add up all these costs and give me an approximate number. It has a drilling depth of up to 45 feet and a hole diameter of up to 12.25 inches. A: Here are a few examples of power generation equipment that could potentially be used for powering mining and refining operations on Psyche, along with their estimated costs: Its worth noting that the cost of power generation 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. Now, all of this is obviously the purest of pure speculation. The concept was later explored by the physicist Freeman Dyson in his 1960 paper "Search for Artificial Stellar Sources of Infrared Radiation". However, I can provide a general step-by-step procedure that would be involved in such an endeavor: Again, its important to note that building a Dyson sphere around the entire solar system is purely hypothetical and far beyond our current technological capabilities. If space vehicles can accelerate to whatever their maximum velocity is, they will also have the capacity to decelerate too. All trademarks are property of their respective owners in the US and other countries. He argued that as the structure would result in the large-scale conversion of starlight into far-infrared radiation, an earth-based search for sources of infrared radiation could identify stars supporting intelligent life. After double-checking my calculations, I have realized that my estimate for the required amount of material for a 1-meter thick Dyson sphere with a radius of 1 AU and a composition of 50% silicon, 30% carbon, and 20% metals was incorrect. Vesta: Vesta is a large asteroid located in the asteroid belt that is thought to contain significant amounts of iron, nickel, and other minerals. Gold: Gold is a highly conductive and corrosion-resistant metal that could be used in the construction of the Dyson spheres electrical components. The choice of asteroid would depend on a variety of factors, including its composition, location, and accessibility, as well as the cost and technology required to extract and transport the desired materials. How much material would I need to build this Dyson sphere? Scientists have upped the ante on theoretical Dyson Spheres with a proposal for alien civilizations constructing the colossal megastructures around stellar mass black The form of 'biosphere' which I envisaged con It could be used for constructing the solar panels and for other parts of the Dyson sphere that require light, yet strong materials. [14][15] However, subsequent analysis showed that the results were consistent with the presence of dust. When NikolaiKardashev later devised a scale for classifying advanced aliens based on their capacities to harvest energy, he used the Dyson Sphere as a signature of a Type II civilization. Therefore, 4 x 10^20 kilograms of material would not be sufficient to construct a Dyson sphere of the size and composition you specified. Converting all those hard X-rays to some form that's easier to transmit or store. You can find him online on Twitter at @thisdotjohn, Currently playing: Deep Rock Galactic, Destiny 2, Microsoft is holding a surprise event and it might be about Bing and ChatGPT, Watch and freak out a little as Boston Dynamics puts Atlas robot to work, Quordle today - hints and answers for Tuesday, April 18 (game #449). This, they say, will likely be in the form of waste heat that we can observe with infrared spectrum technology. If you built the sphere, at the optimum radial distance, then insulated the exterior as much as possible, would the gravitational redshift provided by the black hole not act to sort out your problem for you, if you want to dissipate it, as far as co-ordinate observers at any reasonable distance were concerned? So one way to find out alien civilizations would be to look for signatures of this infrared radiation in space. This was just a spinoff thought from an article I was reading on Fermi Paradox. As for how your managed BH Dyson sphere might fare, have you ever seen a Chinese lantern catch fire? 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. Spellcaster Dragons Casting with legendary actions? can one turn left and right at a red light with dual lane turns? If we improve the efficiency and reduce the cost of materials through technological developments a trend that has been the norm and not the exception throughout human history the timelines could be shorter. A swarm of orbiting energy conversion satellites whose orbits leave hole in the swarm from time to time for more matter to be fed in is far more practical. To learn more, see our tips on writing great answers. 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. To absorb the accretion disc luminosity, a Dyson ring or a Dyson Swarm could be a By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. I expect there would be neutrinos too, but it's still a pretty dramatic conversion of matter into energy. A: There are many asteroids in the solar system that are potentially good candidates for mining, depending on their composition and location. 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. By creating a space-based structure, an alien civilization could meet the energy needs to push its civilization to the next level. anyway the smallest stellar black hole would be at least above 3 solar masses so either depends on your mass a stable orbit without artificial acceleration is given by Force(net) equal to (Mass(1 swarm) multiply by velocity square) divided by distance. When the pencil hits the floor this kinetic energy is dissipated, and you're left with a mass deficit. Plan the mission: Based on the composition of the asteroid, a mining mission can be planned. A large dyson sphere encircling a neutron star at the high end of the mass spectrum will bend light differently to a black hole. In a recent study, scientists analyzed the possibility of an advanced civilization harvesting energy from a black hole. :D, I wish I'll have some energy fraction gettable from previous spheres as well as a reward. Copy a link to the article entitled http://Could%20aliens%20suck%20the%20energy%20from%20black%20holes%20with%20Dyson%20Spheres? By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Here are some of the major sources for the metals mentioned in my previous answer: These sources are not exhaustive and there may be other sources for these metals that are not listed here. Theres also a possibility that a meteor or asteroid could nudge one of the pieces out of place. 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. Honeybee Robotics Planetary Deep Drill: This is a lightweight, compact drill designed for deep drilling on other planets and asteroids. 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. For doing this, borrowing an idea from Olaf Stapledon, Dyson imagined the civilization taking apart a number of the planets and other material in their solar system to build a shell of material that would fully enclose their planet, thus capturing far more of the heat than what they could otherwise. If the percentage of such atypical wavelengths were to be significant, an alien megastructure could be detected at interstellar distances. Q: I think you have made a mistake. Something's wrong. Please fill out the form below to get our email with all the posts from the previous 24 hours, which is sent out a bit after midnight (NY City time) each day. {notificationOpen=false}, 2000);" x-data="{notificationOpen: false, notificationTimeout: undefined, notificationText: ''}">. However, we can make some rough estimates based on current material prices and assumptions. 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. I don't think so Dirk. For a Dyson sphere thats at 2 AU and 2 meters thick, how many asteroids would we need to completely mine? Life support equipment: A life support system is essential for providing astronauts with breathable air, removing carbon dioxide and other contaminants, and regulating temperature and humidity. Q: Given the current prices of materials, how much would 1.901 x 10^27 kilograms of material for the above Dyson sphere cost? There will be a component of velocity due to the black hole's gravitation. "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.". Iron (used instead of crude steel): $0.20 per kilogram. One possible option would be the Space Launch System (SLS), a rocket being developed by NASA that is designed to carry heavy payloads into deep space. Q: What would be a good way to send all this equipment to Psyche? Use MathJax to format equations. In principle, no, you cannot make a Dyson sphere which is indistinguishable from the CMB. The reason is fairly simple. Let's start with a blackbody This energy-capturing sphere would radiate its enormous waste heat out in the infrared spectrum. In fictional accounts, the Dyson-sphere concept is often interpreted as an artificial, hollow sphere of matter around a star. The estimated cost for a new 797F is around $5 million. The wavelengths of such re-radiated energy may be atypical for the star's spectral type, due to the presence of heavy elements not naturally ocurring within the star. All that said, even though we imagine black holes as energy sinks rather than generators, that is not entirely the case. Multi-junction solar cells: These are a type of solar cell that use multiple layers of semiconductor material to absorb a wider range of wavelengths of light, resulting in higher efficiency. If you truly want to understand modern astrophysics, knowing how to read this graph is essential. Silicon, carbon, and metals are likely to be among the most commonly used materials. I asked AI engine chatGPT to build me a hypothetical 2 meter thick Dyson sphere at a distance of 2 AU (~300 million kilometers). The estimated cost for a new InLine Leach Reactor ranges from $500,000 to $1.5 million, depending on the size and configuration. I must say I am enormously impressed. [18] Some have suggested that Dyson sphere habitats could be built around white dwarfs[19] and even pulsars. That's because the potential energy is mass-energy, in the pencil. Determine the optimal distance from the sun at which to place the Dyson sphere. Don't forget the sphere would experience time dilation, so that's a factor. If we want to dream, we might as well dream big. Probably ONLY when you research the final tech, aka, Looping. The SLS is currently in development and is scheduled to make its first launch in the coming years. The next major revision was designed by S. Abbas Raza, building upon the earlier look, and coded byDumky de Wildein 2013. A growing alien civilization may need to develop a way to harvest the energy of their host star. ($10,00 quadrillion for Psyche sounded attractive, so I focused on Psyche). New blog post from our CEO Prashanth: Community is the future of AI, Improving the copy in the close modal and post notices - 2023 edition. Assuming an average metal content of 10% by mass, this would give us around 2.8 x 10^20 kilograms of metal available from the asteroid belt. If we want to find extraterrestrials, we should follow their energy trail. It is estimated to be worth over $10,000 quadrillion, making it one of the most valuable objects in the solar system. 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. 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. 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. Taking all of that into account, the paper suggests that a Dyson sphere around a black hole could harvest roughly five times more energy than that available around a star. Per the Stefan-Boltzmann Law, emitted power P is related to temperature T by $$P = \sigma T^4$$ where the Stefan-Boltzmann constant is $$\sigma = 5.6710^{8} W m^{2} K^{4}$$ This is completely free of charge for everyone. Valve Corporation. A: To estimate how many asteroids we would need to mine to obtain enough materials for a Dyson sphere at a distance of 2 AU and 2 meters thick, we would need to make several assumptions about the composition of the asteroids and the efficiency of our mining and refining processes. How to intersect two lines that are not touching. WebA black hole with the same mass has a diameter of under three. 2023 BDG Media, Inc. All rights reserved. New York, Is it considered impolite to mention seeing a new city as an incentive for conference attendance? It would be tricky to insulate against that. Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. The estimated cost for a new Kaldo furnace is around $10 million. Visit our corporate site (opens in new tab). If you built the sphere, at the optimum radial distance, then insulated the exterior as much as possible, would the gravitational redshift provide 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? Is there a way to use any communication without a CPU? The estimated cost for a new MT 5500AC is around $5 million. Why is a "TeX point" slightly larger than an "American point"? Or at least, harder to tell that it was a Dyson Sphere.. Let's say an individual's memories and mind fit into 2.5 terabytes of storage, which is an extremely low estimatethat means there's a server farm somewhere with 20 billion terabytes, which is 20 million petabytes, or about 20 exabytes. Freeman Dyson proposed the idea in the early 1960s. Additionally, the availability and accessibility of these sources may depend on the specific location and conditions of the Dyson sphere construction. How can I detect when a signal becomes noisy? $6.117 x 10^33 = $85 trillion x (1 + 0.025)^n, (1 + 0.025)^n = ($6.117 x 10^33) / ($85 trillion). Platinum: Platinum is a valuable metal that is highly resistant to corrosion and oxidation, making it useful in a variety of industrial and scientific applications, including the construction of the Dyson spheres electrical components. This is the point at which an Earth far into the future might need to harness the full power of the sun, and the point at which we'd become a Kardashev type 2 civilization. Can we create two different filesystems on a single partition. What would it take to mine asteroids for procuring this material? And that's your homework! But, the galaxy is an immense place with an estimated 400 billion stars in it. Q: Ok. Lets reduce the size of the Dyson sphere. The minimum safe distance for components of a dyson swarm will be determined by the maximum safe orbital velocity for the individual units of the swarm. Doing that is really hard work because it isn't gravitationally stable. Earth is far from using a Dyson sphere to harvest our sun, Jupiter, or even a black hole. Therefore, at the current world GDP growth rate of 2.5%, it would take approximately 572.5 years for world GDP to reach $6.117 x 10^33. The recent study suggests that instead of building a Dyson sphere around a star, a civilization can build the same megastructure around black holes. One example is the Extravehicular Mobility Unit (EMU) used by NASA for spacewalks. RASSOR: The Regolith Advanced Surface Systems Operations Robot (RASSOR) is a mining robot designed for use on the Moon and other planetary bodies. Building one in the extreme environment around a binary system with a black hole would be even harder, especially if you wanted to capture energy from the jets. Why should there be an accretion disc? "An accretion disk, a corona, and relativistic jets could be potential power stations for a Type II civilization," the researchers write. Identify asteroids: The first step in asteroid mining is to identify suitable asteroids. However, we've yet to even find traces of bacteria on another world, much less something this, well, epic in scale. A: Asteroid mining is a potential source of various metals that could be used for building a Dyson sphere around the solar system. Fictional depictions often describe a solid shell of matter enclosing a star an arrangement considered by Dyson himself to be implausible. Named by the CTA as a CES 2020 Media Trailblazer for his science and technology reporting, John specializes in all areas of computer science, including industry news, hardware reviews, PC gaming, as well as general science writing and the social impact of the tech industry. [9][10] Fermilab discovered 17 potential "ambiguous" candidates, of which four were in 2006 called "amusing but still questionable". You would probably have to ground up whole planets just to get the material you need. It uses a rotary-percussive drilling method and can drill up to one meter deep. 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. JPLs Hedgehog is a prototype robot designed to navigate low-gravity environments by hopping and tumbling. The first modern imagining of such a structure was by Olaf Stapledon in his science fiction novel Star Maker (1937). Building a Dyson Shell around a black hole? [2][3] They are sometimes used as the type of plot device known as a Big Dumb Object. 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. Dyson proposed the spheres as a solution to a growing alien civilization needing a large enough energy output to sustain its existence. If you want to have so many of them that you block a significant amount of the sun's light, then we would need to build billions and billions more of them. Heres how it works. Scientists believe that every major galaxy has a black hole lurking at its center. Nickel: Nickel is commonly used in alloys to improve their strength, ductility, and resistance to high temperatures, making it useful for the construction of the Dyson spheres heat-resistant components. The estimated cost for a new LM90 is around $500,000. The number of craft required to obtain, transmit, and maintain a complete Dyson sphere exceeds present-day industrial capabilities. Extract the metals: There are several methods that could be used to extract metals from asteroids, including drilling, blasting, and crushing. WebDyson Sphere Program Find A Black Hole#BlackHole #DysonSphereProgram A black hole comprises this singularity and its event horizon, which is simply the black holes surface of no return. In a new study published in the Monthly Notices of the Royal Astronomical Society (opens in new tab), researchers from Taiwan's National Tsing Hua University (NTHU) dig into the energy output from a stellar mass black hole and found that the energy captured would be immense and would dwarf the amount of energy captured by their own sun. The Environmental Control and Life Support System (ECLSS) used on the International Space Station costs around $250 million. The estimated cost for a new If that is close enough to "insignificant", there is no need to go further. However, its important to keep in mind that this estimate is very rough and does not take into account many factors that could significantly affect the actual number of asteroids required, such as the specific composition of the asteroids and the efficiency of our mining and refining processes. Dyson shell is (unfortunately) impossible to build. By subscribing to this BDG newsletter, you agree to our. What could be better than a super freaky idea from the edges of astrophysics? Advanced civilizations would likely try to capture all the energy of their star to grow. If we were to mine asteroids, what kind of construction, human support, transportation and communication equipment would we need? However, here are some very rough estimates based on current average prices: Using these rough estimates, the cost of 1.901 x 10^27 kilograms of material for the Dyson sphere would be approximately: (0.5 x 1.901 x 10^27 x 0.8) + (0.3 x 1.901 x 10^27 x 1.5) + (0.2 x 1.901 x 10^27 x 1) = $6.117 x 10^33. However, here is a rough estimate of the costs of some of the equipment we have discussed: Overall, its possible that the total cost of the equipment required for a mining mission to Psyche could be in the range of several billion dollars.
