What metals could best be mined from asteroids for our purpose? Ceres: Ceres is a dwarf planet located in the asteroid belt between Mars and Jupiter. [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]. If you want to understand what the Universe is, how it began, evolved, and will eventually end, astrophysics is the only way to go. Bennu: Bennu is a carbonaceous asteroid that is currently being studied by NASAs OSIRIS-REx mission. While the jets speeding out from the poles of a stellar-mass black hole are nothing like those of supermassive black holes, the principle is the same, and the energy they represent is substantial. Lets unpack things a bit. Falling bodies do not slow down. The mass of an average asteroid can vary widely, but we can use the mass of the largest known metallic asteroid, 16 Psyche, as an estimate. You have no materials. Dyson theorized that as the energy requirements of an advanced technological civilization increased, there would come a time when it would need to systematically harvest the energy from its local star on a large scale. It has a drilling depth of up to 45 feet and a hole diameter of up to 12.25 inches. Q: Ok. Lets go down the list of equipment one by one. Q: Ok, now lets go back to building a Dyson sphere using metals and other materials from asteroids like Psyche. A solar-sized black hole (BH) has a diameter of about 6000 m. It's apparent area is then $$A' = 4\pi r^2 = 4 \pi ({3000}^2) = 1.1 \times 10^8 m^2$$. One example is the Extravehicular Mobility Unit (EMU) used by NASA for spacewalks. The questions I answered were simple, the answers complex. 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. answer to the above: construct the swarm to be inclusive of a repulsive gravitational field (similar the the astrophysical structure of a pulsar) oscillated/emitted from the swarm itself to sustain around the hole, additionally have each equipped with a laser based projection optical ray to catalyze the accretion disk for higher power achievement through absorption by the swarm. which is a just about $10^7$light-seconds, or 0.3 light-years. 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. How to intersect two lines that are not touching. 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. WebA black hole with the same mass has a diameter of under three. Caroline Delbert is a writer, avid reader, and contributing editor at Pop Mech. 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). George Dvorsky has advocated the use of self-replicating robots to overcome this limitation in the relatively near term. What is the difference between these 2 index setups? All rights reserved. Nickel Nickel is abundant in the metallic cores of the rocky planets and can also be found in asteroids and comets. Will this type of structure be added in the future? The difference is that the surface power is only radiated over a hemisphere rather than a full 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. 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. 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. Her favorite topics include nuclear energy, cosmology, math of everyday things, and the philosophy of it all. [1][2][3] The concept is a thought experiment that attempts to imagine how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet's resources alone. Assuming a thickness of 2 m and a density of 2.5 g/cm^3, the total mass of the Dyson sphere would be approximately: Mass = (4/3) * pi * (2 AU)^3 * (2.5 g/cm^3) * (2 m) 1.67 x 10^24 g. Using the same mix of 50% silicon, 25% carbon, and 25% metals by weight, the mass of each material required would be: As for the costs, using the same prices as in my previous response, the total cost of the materials required to build the Dyson sphere would be: The total cost would depend on the specific prices of the materials used and their availability. 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. The estimated cost of RASSOR is $15 million. Silicon, carbon, and metals are likely to be among the most commonly used materials. Install a network of mirrors and other devices to focus and redirect the suns energy towards the inhabited areas of the Dyson sphere. But Wright suggests it might be exceedingly difficult. Next come black holes, which are far more well known. 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. There are a few people who think about looking for them, they are looking for large structures that might pass in front of the star or anything else, but large things, Jason Wright, a Penn State astronomer and director of the Penn State Extraterrestrial Intelligence Center, tells Inverse. That part requires thinking beyond just the Dyson sphere and expanding to a Dyson swarm or bubble. GRBs don't happen for nothing. Therefore, it's a theoretical device that sits around an entire star and harvests its energy. Here are some estimates: Based on these estimates, its possible that mining all of the asteroids in the solar system, as well as Io, Callisto, Ganymede, Europa, and Mercury, could yield a total of around 4 x 10^20 kilograms of metal, as well as significant amounts of water ice, sulfur, and other volatiles. Would 4 x 10^20 kilograms of material be enough to construct a Dyson sphere that is 1 m thick, 1 AU from the sun and is 50% silicon, 30% carbon and 20% metals? For the uninitiated, prolific scholar Freeman Dyson first described his namesake Dyson sphere concept in a landmark 1960 paper. That's because the "coordinate" speed of light at the ceiling is circa 4 m/s greater then the coordinate speed of light at the floor. Why hasn't the Attorney General investigated Justice Thomas? One example of an SOFC that could be used for this application is the Bloom Energy Server. 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. It builds quickly and keeps every ray received in line of sight, and also makes the dyson sphere look like a giant Saturn. Honestly. Would it be possible to have a small black hole dissipate as it 'sinks' into the earth? Dextre: Dextre is a robotic arm used on the International Space Station (ISS) for maintenance and repair tasks. If we were to mine asteroids, what kind of construction, human support, transportation and communication equipment would we need? Using current telescopes such as the Galaxy Evolution Explorer, an orbiting space telescope launched in 2003, the authors argue that one could detect such structure around a distant star. Worldbuilding Stack Exchange is a question and answer site for writers/artists using science, geography and culture to construct imaginary worlds and settings. What is the etymology of the term space-time? Therefore, its unlikely that we would have enough material to construct a Dyson sphere of the size and composition you specified using only the asteroids and selected moons mentioned earlier. WebThe cluster contains two Blue Giants, one Red Giant, 4 O types, and 19 B types, with the black hole a good distance from the starting system and the neutron star very far from the starting system. WebBlack Holes could actually theoretically be used to harvest energy in a lot of ways, the chief one being using its gravitational force to accelerate light beamed into its vicinity and then Additionally, the cost would depend on the specific design and capabilities of the refining equipment required for the mission. A: Building a Dyson sphere would require a variety of metals for various purposes, such as constructing the framework, providing structural support, and facilitating energy transmission. There are quantised zones where orbits are possible or not possible, so dont take other answers at face value if they involve relativistic speeds or distances within a few radii. : You cant pull energy out of a black hole, its physically imposible, just like you cant travel in time. 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. Webb Space Telescope Image Shows Bright Galactic Collision, 2.29 billion years ago, This Cataclysmic Event Transformed the Makeup of Earths Crust. Of all the considered parameters, the researchers conclude, just the accretion disk, the corona (which is the plasma gas surrounding a black hole), and the relativistic jets are promising energy sources. If space vehicles can accelerate to whatever their maximum velocity is, they will also have the capacity to decelerate too. You can, of course, decrease the difference by making the DS larger. Atlas Copcos DM30 II is a large rotary drill rig used in surface mining operations. Solving for the radius of the sphere R gives $$R = 3\times 10^{15} meters$$ RASSOR: The Regolith Advanced Surface Systems Operations Robot (RASSOR) is a mining robot designed for use on the Moon and other planetary bodies. The calculation includes a number of approximations, but 600 years is a very short period of time based on astronomical and even civilizational timescales. For example, Matrioshka brains have been proposed to extract energy for computation, while Shkadov thrusters would extract energy for propulsion. Valve Corporation. This would require specialized storage containers and transportation equipment, such as spacecraft or cargo ships. Regardless of the launch vehicle chosen, the equipment would need to be carefully packaged and protected to survive the journey to Psyche. Gold: Gold is a highly conductive and corrosion-resistant metal that could be used in the construction of the Dyson spheres electrical components. The estimated cost of a small modular reactor ranges from $500 million to $1 billion, depending on the design and capabilities. For a Dyson sphere thats at 2 AU and 2 meters thick, how many asteroids would we need to completely mine? on LinkedIn. A: You are correct, I apologize for the mistake in my previous response. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. If you transmit it, relativity makes that complicated; if you store it, you have to lift it out of the black hole's gravity well. Hertzsprung-Russell diagram: the most important graph in astrophysics, Exoplanets with moons may be likelier to host life, A fable of ancient Greece: when the mythic universe became a rational machine, Tolkien on the importance of fantasy and science fiction, Longer naps in the day may be an early sign of dementia in olderadults. A Dyson Sphere, a spherical structure that surrounds a star and transports its radiative energy outward as an energy source for an advanced civilisation, is one of the Begin constructing the Dyson sphere by launching robotic spacecraft into space that can collect raw materials from nearby asteroids and comets. Callisto: Callisto is another moon of Jupiter and is thought to have a rocky, icy surface. The main use of building a Dyson swarm around a black hole would be to capture the energy released by its accretion disk. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Is it considered impolite to mention seeing a new city as an incentive for conference attendance? However, this step-by-step procedure provides a general outline of the tasks that would be involved if such a project were to be attempted. The next major revision was designed by S. Abbas Raza, building upon the earlier look, and coded byDumky de Wildein 2013. Even if we assume that all of this material is usable for constructing the Dyson sphere and that it has the desired composition of 50% silicon, 30% carbon, and 20% metals, it still wouldnt be enough to construct a Dyson sphere with a radius of 1 AU and a thickness of 1 meter. At the heart of his theory is a simplebut tantalizingquestion: if a civilization grew large enough, and traveled far enough afield into outer space, how would it have enough energy to power itself? Storage and transportation equipment: The refined metal would then need to be stored and transported to a construction site or to Earth. I hope it is clear that the BH heat sinking has little effect on the energy balance of the DS. "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.". Black holes make better engines for Dyson Spheres than stars. Because of the difference in the coordinate speed of light up here as opposed to down there. Can't better your answer.The best part of giving a wrong answer is it spurs other people to give one you can learn from, both yours and John on this page. [2][3] They are sometimes used as the type of plot device known as a Big Dumb Object. .css-v1xtj3{display:block;font-family:FreightSansW01,Helvetica,Arial,Sans-serif;font-weight:100;margin-bottom:0;margin-top:0;-webkit-text-decoration:none;text-decoration:none;}@media (any-hover: hover){.css-v1xtj3:hover{color:link-hover;}}@media(max-width: 48rem){.css-v1xtj3{font-size:1.1387rem;line-height:1.2;margin-bottom:1rem;margin-top:0.625rem;}}@media(min-width: 40.625rem){.css-v1xtj3{line-height:1.2;}}@media(min-width: 48rem){.css-v1xtj3{font-size:1.18581rem;line-height:1.2;margin-bottom:0.5rem;margin-top:0rem;}}@media(min-width: 64rem){.css-v1xtj3{font-size:1.23488rem;line-height:1.2;margin-top:0.9375rem;}}All You Need to Know About Supernovae, Everything You Need to Know About Wolf-Rayet Stars, Meet the First Woman Astronaut on a Moon Mission. The estimated cost for a new HIGmill ranges from $500,000 to $5 million, depending on the size and configuration. It could also be used for mining operations on an asteroid, such as moving and manipulating mining equipment. Therefore, 4 x 10^20 kilograms of material would not be sufficient to construct a Dyson sphere of the size and composition you specified. Titanium Titanium is a lightweight and strong metal that is also corrosion-resistant. More information: Tiger Yu-Yang Hsiao et al, A Dyson sphere around a black hole, Monthly Notices of the Royal Astronomical Society (2021). 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. Gekko Systems InLine Leach Reactor is a modular system used for leaching and recovering metals from ores and concentrates. "An accretion disk, a corona, and relativistic jets could be potential power stations for a Type II civilization," the researchers write. This means that a Penrose sphere is far smaller than a Dyson sphere encasing a star of equivalent mass. 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. So the efficiency $\eta$ of the BH as an energy absorber is $$\eta = \frac{A'}{\frac{A}{2}} = \frac{1.1 \times 10^8}{.6\times 10^{32}} = 2\times 10^{-24}$$. Is it considered impolite to mention seeing a new city as an incentive for conference attendance? [8], SETI has looked for such infrared-heavy spectra from solar analogs, as has Fermilab. The estimated cost for the RASSOR project is around $3 million. Q: Ok. Give me a detailed plan for mining asteroids for some of these metals. This would include satellite communication systems, GPS, and other navigation tools. We Know How Fast Earth Spins Dont We? It only takes a minute to sign up. Can we create two different filesystems on a single partition. And what Winterberg is saying is that something's got to give, like the wave nature of matter. The estimated cost for a new Transloader ranges from $200,000 to $500,000, depending on the size and configuration. It was later upgraded extensively byDan Balisin 2006. The sphere has been traveling towards the galactic core for several billion years at sub-light speed and intends to enter a black hole as part of an ancient compact. After all, dont black holes swallow everything that falls into the event horizon, including light? Thermodynamically possible to hide a Dyson sphere? Specifically, a sphere with the diame Continue Reading A relativistic Kessler cascade is going to be a horrible problem. 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. It radiates a lot of energy. 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. The estimated cost for a new LM90 is around $500,000. Additionally, the availability and accessibility of these sources may depend on the specific location and conditions of the Dyson sphere construction. I can think of another reason: use it as a. WebThey only spawn in small amounts, and only occur on planets orbiting neutron stars and black holes, and are only used for making Particle Container and the Plane Smelter . 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? Europa: Europa is another moon of Jupiter and is thought to have a subsurface ocean beneath its icy surface. Try two super freaky ideas from the edges of astrophysics. Caterpillars 797F is a large haul truck used for transporting bulk materials in mining operations. The estimated cost for a new DE880 is around $1.5 million. However, we've yet to even find traces of bacteria on another world, much less something this, well, epic in scale. The Fermi Paradox, Explained. A Dyson Swarm around the sun that harvested most of its energy would yield power measured in the trillions upon trillions of watts. Thin-film solar cells: These are a type of solar cell that use a thin layer of semiconductor material deposited on a substrate, resulting in lower material costs and greater flexibility. Lets describe them nevertheless. As for how your managed BH Dyson sphere might fare, have you ever seen a Chinese lantern catch fire? Alternately, you can think about an entire world powered by electric batteries instead of fossil fuels. 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. Further out, it will be much simpler and easier, but require more materials. " The black hole is surrounded by its event horizon, a boundary that outlines the black hole from which nothing that enters the black hole can be observed from outside. 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. Solar panels could be used to generate electricity on the asteroids surface, or a nuclear reactor could be used for continuous power generation. Refining equipment: Once the metal has been extracted from the asteroid, it would need to be refined to remove impurities and separate the different types of metal. 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. 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. WebDyson Sphere Program Find A Black Hole#BlackHole #DysonSphereProgram All trademarks are property of their respective owners in the US and other countries. Q: You assumed a radius of 1 AU in the calculation above. NOTE: This answer has limited itself to considering a possible minimum safe distance for a dyson swarm and not a dyson shell. Orbits are not required for keeping rings or spheres in place. You're forgetting that the gravitational pull of the black hole will speed up the swarm units as they approach; as an example. A: I apologize for the error in my previous response. In the English translation of his 1920 book "Relativity: the special and general theory" he wrote: "according to the general theory of relativity, the law of the constancy of the velocity [Einstein clearly means speed here, since velocity (a vector) is not in keeping with the rest of his sentence] of light in vacuo, which constitutes one of the two fundamental assumptions in the special theory of relativity [] cannot claim any unlimited validity. I'd suggest that "minimum" distance depends more upon the technology available to the builders than anything else. According to Tolkien, fantasy requires a deep imagination known as sub-creation. And the genre reflects a fundamental truth of being human. A growing alien civilization may need to develop a way to harvest the energy of their host star. Cimarrons Transloaders are mobile conveyor systems used for loading and unloading bulk materials. Think about the energy required to carry more and more people into space as the world's billionaires venture outside of our planet, plus the energy demands for NASA's own ambitions to install people on the moon. This difference in speeds is precisely that referred to above by ceiling and floor observers. Q: Ok, now lets see a few examples of relevant storage and transportation equipment and their approximate costs. 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. Copy a link to the article entitled http://Could%20aliens%20suck%20the%20energy%20from%20black%20holes%20with%20Dyson%20Spheres? Would that give us enough material? DOI: Time would move slower. The combined mass of Jupiter and Mercury is only approximately 1.901 x 10^27 kilograms, which is still significantly less than the required amount of material. Therefore, we would still 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, in order to construct a Dyson sphere of the size and composition you specified.
