A Dyson swarm is a collection of individual, smaller "harvesters" of some kindthat could be solar panels used extremely close up, for examplethat are loosely circulated. In addition, Io is thought to have significant deposits of iron, nickel, and other metals, although the exact amounts are uncertain. Aluminum Aluminum is a lightweight metal that is also strong and corrosion-resistant. Based on the calculations I provided earlier, constructing a Dyson sphere with a radius of 1 AU and a thickness of 1 meter would require approximately 9.1 x 10^25 kilograms of material, assuming the material is evenly distributed across the sphere and has a density of 2 grams per cubic centimeter. The Dyson sphere is the ultimate end goal of the Dyson Sphere Program. I can think of another reason: use it as a. 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. Another civilization, with even higher energy demands than what we've outlined above, might decide to deploy a Dyson sphere around a black hole, which is where these researchers began their work. Titanium Titanium is a lightweight and strong metal that is also corrosion-resistant. Future US, Inc. Full 7th Floor, 130 West 42nd Street, Sandviks DE880 is a core drilling rig used for mineral exploration and geotechnical investigation. All trademarks are property of their respective owners in the US and other countries. What would it take to mine asteroids for procuring this material? Estimates suggest that Ganymedes surface may contain around 5 x 10^18 kilograms of metal. 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 composition of this material would include silicon, carbon and metals. Based on estimates from the Galileo mission, its been suggested that Ios surface may contain around 10^18 kilograms of sulfur. WebA solar-sized black hole (BH) has a diameter of about 6000 m. It's apparent area is then A = 4 r 2 = 4 ( 3000 2) = 1.1 10 8 m 2 Since a blackbody radiates uniformly in all It could be used for the framework and support structure of the Dyson sphere. Doing that is really hard work because it isn't gravitationally stable. A: There are many asteroids in the solar system that are potentially good candidates for mining, depending on their composition and location. This is only more vital if the energy source is a black hole rather than a traditional star. Its design could potentially be adapted for use on Psyche to mine the asteroids metal surface. I am reviewing a very bad paper - do I have to be nice? While the hot material stays beyond the singularitys event horizon, it can emit energy that radiates away into space. Things that will actually happen in our time and are not added to the game, at least not to my awareness. Life finds a way particularly if it has a moon. Share Could aliens suck the energy from black holes with Dyson Spheres? rev2023.4.17.43393. 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. [7], Dyson-style energy collectors around a distant star would absorb and re-radiate energy from the star. Recheck that answer. Additionally, the cost would depend on the specific design and capabilities of the refining equipment required for the mission. 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. I was thinking of a radius of 2 AU. 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. A: Here are a few examples of drilling and mining robots that could be used for mining operations on an asteroid like Psyche: Its worth noting that the specific type of drilling and mining robots that would be used for the mission to Psyche would depend on a variety of factors, including the mission requirements, the specific characteristics of the asteroid, and the available technology at the time of the mission. 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. Q: Ok, now add up all these costs and give me an approximate number. The estimated cost for a new Metal Bin ranges from $5,000 to $20,000, depending on the size and configuration. About one one-billionth of the Suns total energy output actually reaches the Earth. on LinkedIn. A: Here are a few examples of communication and navigation equipment that could be used for the mission to Psyche, along with their estimated costs: Its worth noting that the cost of communication and navigation equipment for use on the mission to 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 deep space and an asteroid. Further out, it will be much simpler and easier, but require more materials" Aluminum Aluminum is also abundant in the solar system and can be found in a variety of sources, including the crusts of the rocky planets, asteroids, and comets. As of April 2023, the price per kilogram of silicon, carbon, and steel are approximately: Using these prices, the total cost of the materials required to build the Dyson sphere would be: Again, these estimates should be taken with a grain of salt, as the engineering and construction of a Dyson sphere is purely hypothetical and would involve many unknown factors. Gear-obsessed editors choose every product we review. Give me a few examples of mining robots for mining metals on Psyche and their approximate cost. Why? A: I apologize for the error in my previous response. Copper Copper is a good conductor of electricity and could be used for wiring and electrical components of the Dyson sphere. Would accretion discs and the massive gravity well pulling in everything around you not be a worry, in the future? How challenging? Additionally, the cost of actually constructing the Dyson sphere would likely be much higher than just the cost of materials, as it would involve a massive engineering and construction effort on an unprecedented scale. It builds quickly and keeps every ray received in line of sight, and also makes the dyson sphere look like a giant Saturn. Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. Towing them around does require a rather large-scale propulsion system, though. Titanium Titanium is relatively abundant in the solar system and is found in the crusts of the rocky planets, as well as in some asteroids and comets. He speculated that this could be done via a system of structures orbiting the star, designed to intercept and collect its energy. Additionally, the cost would depend on the specific design and capabilities of the equipment required for the mission. Could you build a stable structure just short of the Schwarzschild radius or would you need to move farther back to be safe? [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. [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". Nassim Nicholas Taleb, author of Fooled by Randomness and The Black Swan. 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. In 1960, physicist Freeman Dyson put forth a paper in Science that changed the way we talked about alien civilizations. Because of the difference in the coordinate speed of light up here as opposed to down there. {notificationOpen=false}, 2000);" x-data="{notificationOpen: false, notificationTimeout: undefined, notificationText: ''}">. More information: Tiger Yu-Yang Hsiao et al, A Dyson sphere around a black hole, Monthly Notices of the Royal Astronomical Society (2021). The first question you are probably asking is, how can you get any energy out of a black hole? Launch these components into space and gradually attach them to the Dyson sphere until it fully encloses the solar system. I don't think so Dirk. GRBs don't happen for nothing. See this 2001 paper by Friedwardt Winterberg. I think it's essentially correct. Why? Take a The estimated cost for the RASSOR project is around $3 million. Try two super freaky ideas from the edges of astrophysics. With tweaks that ensure even greater accuracy, we will soon be using chatGPT and its descendants to design complex technological projects and explore creative ideas. Its goal is to help power a civilization whose energy demands have simply eclipsed their planet's natural potential. Ceres: Ceres is a dwarf planet located in the asteroid belt between Mars and Jupiter. When the pencil hits the floor this kinetic energy is dissipated, and you're left with a mass deficit. 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. It could also be used for mining operations on an asteroid, such as moving and manipulating mining equipment. 3 Quarks Daily started in 2004 with the idea of creating a curated retreat for everything intellectual on the web. A Dyson shell is (unfortunately) impossible to build. Thanks for contributing an answer to Physics Stack Exchange! 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. Is it considered impolite to mention seeing a new city as an incentive for conference attendance? Hsiao and his collaborators from the Institute of Astronomy in Taiwan, brings us to the very edge of possibility itself. Communication equipment: Communication equipment is critical for maintaining contact with the mining and refining operations on Psyche, as well as for transmitting data and other information back to Earth. It has a drilling depth of up to 45 feet and a hole diameter of up to 12.25 inches. Q: What if we include Jupiter and Mercury and completely disassemble them? However, this is a rough estimate and the actual cost would depend on a wide variety of factors, including the specific mission requirements, the state of technology at the time of the mission, and the availability of funding. 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. Don't forget the sphere would experience time dilation, so that's a factor. This would require specialized refining equipment, such as smelters and chemical processing equipment. The dyson sphere would have to be constructed in such a way that its mass was uniform in all directions done the planck length. 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. Why is a "TeX point" slightly larger than an "American point"? A recent paper published in Monthly Notices of the Royal Astronomical Society suggests that scientists should start to look for Dyson spheres around black holes as an indication of an alien civilization. Put someone on the same pedestal as another, What are possible reasons a sound may be continually clicking (low amplitude, no sudden changes in amplitude), Dystopian Science Fiction story about virtual reality (called being hooked-up) from the 1960's-70's. Connect and share knowledge within a single location that is structured and easy to search. [11][12][13], On 14 October 2015, Planet Hunters' citizen scientists discovered unusual light fluctuations of the star KIC 8462852 raising press speculation that a Dyson sphere may have been discovered. 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. It was later upgraded extensively byDan Balisin 2006. The estimated cost of Dextre is $200 million. 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. 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. Estimates suggest that Callistos surface may contain around 5 x 10^17 kilograms of water ice, as well as significant amounts of other volatiles such as carbon dioxide and ammonia. Give me some numerical estimates and costs based on current material prices for a 2 m thick Dyson sphere at 2 AU distance from the sun.

Dyson shell is (unfortunately) impossible to build. You'll also have to arrange for occasional gaps in the swarm to allow more matter to be fed to the accretion disc, but that is much easier than the other challenges of this project. Also see Shapiro, and this Baez article: Einstein talked about the speed of light changing in his new theory. Solid oxide fuel cells (SOFCs): These are a type of fuel cell that use a solid oxide electrolyte to produce electricity, typically using natural gas or other hydrocarbon fuels. Copy a link to the article entitled http://Could%20aliens%20suck%20the%20energy%20from%20black%20holes%20with%20Dyson%20Spheres? If you go through a black hole there should be a yes or no prompt to enter a new star system you keep your upgrades and tech. 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 then dependent of the capacity of this world's technology, For example, if the maximum velocity attainable is half the speed of light, then the dyson swarm will be orbiting the black hole with an orbital velocity of approximately 0.5 c. Now you need to factor in the mass of the black hole and will yield what may be the minimum safe distance (assuming there are no other factors to endanger the dyson swarm). Your pencil falls faster and faster and faster, and is allegedly going close to the speed of light at the event horizon, which would represent a huge mass deficit. If nothing else, it would be able to provide excellent starting points. Terexs MT 5500AC is a haul truck used for transporting bulk materials in mining operations. Asking for help, clarification, or responding to other answers. The questions I answered were simple, the answers complex. 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. The researchers behind the new study suggest that building a Dyson sphere around a black hole would allow an alien civilization to garner energy from six sources: By not only relying on radiation as the main source of energy but a Dyson sphere around a black hole would also collect five times as much energy as one around a star, according to the study. What would be its composition? 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. The mission would involve sending a spacecraft to the asteroid to extract the desired metals. Of course, you did specify "significant IR" so there is some wiggle room. To learn more, see our tips on writing great answers. Orbits near a black hole are strange and dont follow Keplers laws, and things are more interesting with rotating BHs. Because its smaller, the Penrose sphere will require far less material. 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). Extract the metals: There are several methods that could be used to extract metals from asteroids, including drilling, blasting, and crushing. 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. Would it be possible to have a small black hole dissipate as it 'sinks' into the earth? Does Chain Lightning deal damage to its original target first? Probably ONLY when you research the final tech, aka, Looping. Not so (in any meaningful way) for the energy which is constantly being generated by the civilization which operates the DS. No, I don't think so. Here are a few examples: Its worth noting that the cost of developing and deploying mining robots for use on Psyche would likely be much higher than the cost of the above projects, due to the unique challenges and extreme environment of mining on an asteroid. We may earn commission if you buy from a link. If the percentage of such atypical wavelengths were to be significant, an alien megastructure could be detected at interstellar distances. The basic component is like a little brick, and we know how to build bricks to build solar panels and load them into space. 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. Q: I think you have made a mistake. The best answers are voted up and rise to the top, Not the answer you're looking for?

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. The next surrounding Dyson sphere would absorb this waste heat and use it for its computational purposes, all while giving off waste heat of its own. The reason is fairly simple. Some way of starting a new system with your upgrades. 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. 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. It has a drilling depth of up to 1,000 meters and a hole diameter of up to 5 inches. Icarus must be a God. ($10,00 quadrillion for Psyche sounded attractive, so I focused on Psyche). It only takes a minute to sign up. 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. Can a black hole be turned into a white hole? Based on the calculations I provided earlier, constructing a Dyson sphere of this size and composition would require approximately 9.1 x 10^25 kilograms of material. For the uninitiated, prolific scholar Freeman Dyson first described his namesake Dyson sphere concept in a landmark 1960 paper. There will be a component of velocity due to the black hole's gravitation. Specifically, a sphere with the diame Continue Reading Iron Iron is one of the most abundant elements in the solar system and can be found in many different sources, including the rocky planets (such as Earth, Mars, and Mercury), asteroids, and the sun. The estimated cost of a small modular reactor ranges from $500 million to $1 billion, depending on the design and capabilities. 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. This calculation suggests that we would need an enormous number of asteroids to mine to obtain enough materials for a Dyson sphere at 2 AU and 2 meters thick. I think it's essentially correct. A relativistic Kessler cascade is going to be a horrible problem. Combining those challenges with the properties of a black hole gets even more tricky. Building a Dyson sphere is about capturing energy output and using that to power to run the civilisation inhabiting the sphere. Worldbuilding Stack Exchange is a question and answer site for writers/artists using science, geography and culture to construct imaginary worlds and settings. Europa: Europa is another moon of Jupiter and is thought to have a subsurface ocean beneath its icy surface. Inspired by the 1937 science fiction novel Star Maker by Olaf Stapledon,[4] the physicist and mathematician Freeman Dyson was the first to formalize the concept of what became known as the "Dyson sphere" in his 1960 Science paper "Search for Artificial Stellar Sources of Infra-Red Radiation". Black Holes store rotational energy that can be harnessed through magnetic reconnection and dropping material in to the ergosphere. Iron (used instead of crude steel): $0.20 per kilogram. Assuming a Dyson sphere with a radius of 1 AU (the distance from the sun to Earth), a thickness of 2 m, and a density of 2.5 g/cm^3 (comparable to the density of rock), the total mass of the Dyson sphere would be approximately: Mass = (4/3) * pi * (1 AU)^3 * (2.5 g/cm^3) * (2 m) 4.18 x 10^23 g. To build such a structure, large quantities of various materials would be required. Connect and share knowledge within a single location that is structured and easy to search. The second outlines impossibly dense regions of space and time surrounded by boundaries that separate their interiors from the rest of the cosmos. We orbit at a distance of 93 million miles (about 150 million km). Use MathJax to format equations. How can I drop 15 V down to 3.7 V to drive a motor? Iron Iron is a common construction material due to its strength, durability, and abundance. 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. They suffer a form of annihilation, and the result is a gamma ray burst. It will be capable of carrying up to 130 metric tons of payload into low Earth orbit, making it one of the most powerful rockets ever built. I was aiming at a ball park estimate instead of an exact figure. Note that it hits the floor at say 4 m/s. A: For fuel cells, some examples that could be used for powering mining and refining operations on Psyche include: For solar panels, some examples that could be used for powering mining and refining operations on Psyche include: Its worth noting that the specific types of fuel cells and solar panels that would be used for the mission would depend on a variety of factors, including the mission requirements, the specific characteristics of the asteroid, and the available technology at the time of the mission. 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. I flew into one, well as best as I could, it didn't do anything. 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. 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. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. The estimated cost for a new DM30 II is around $1.5 million. Older adults who napped at least once or for more than an hour a day had a40% higher chanceof developing Alzheimers than those who napped less. 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. 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. It's part of Dyson's broader suggestion that the Search for Extra Terrestrial Intelligence (SETI) should set their sights on the kind of energy signature that such an item could discharge. [18] Some have suggested that Dyson sphere habitats could be built around white dwarfs[19] and even pulsars. Espaol - Latinoamrica (Spanish - Latin America). What they find could help us reveal what a next-generation galactic civilization might look like, and even help us locate those extraterrestrials in the process. In 1960, physicist Freeman Dyson published a paper in the journal Science describing how a technologically advanced civilization would make its presence known.
