See this 2001 paper by Friedwardt Winterberg. You don't want the elements of your swarm colliding with the accretion disk, so they will need to orbit well clear of it, much farther out than the minimum orbital radius. But what if a more advanced extraterrestrial civilization is not only building megastructures that surround stars, but turning to the infamous beasts of the cosmos for energy: black holes. He later clarified that he did not have in mind a solid structure, saying "A solid shell or ring surrounding a star is mechanically impossible. Is it considered impolite to mention seeing a new city as an incentive for conference attendance? Q: Ok, now lets see a few examples of relevant drilling equipment and their approximate costs. WebA black hole with the same mass has a diameter of under three. Visual Thanks for that. That's because the potential energy is mass-energy, in the pencil. The estimated cost for a new InLine Leach Reactor ranges from $500,000 to $1.5 million, depending on the size and configuration. Don't forget the sphere would experience time dilation, so that's a factor. Put someone on the same pedestal as another. Silicon: (0.5) * (4.18 x 10^23 g) = 2.09 x 10^23 g, Carbon: (0.25) * (4.18 x 10^23 g) = 1.04 x 10^23 g, Metals: (0.25) * (4.18 x 10^23 g) = 1.04 x 10^23 g, Carbon: $1.00 $10.00 per kg (depending on the type of carbon), Silicon: (2.09 x 10^23 g) * ($1.00 $2.50 per kg) $4.18 x 10^23 $1.04 x 10^24, Carbon: (1.04 x 10^23 g) * ($1.00 $10.00 per kg) $1.04 x 10^23 $1.04 x 10^24, Metals: (1.04 x 10^23 g) * ($0.50 $1.50 per kg) $5.21 x 10^22 $1.56 x 10^23, Silicon: (0.5) * (1.67 x 10^24 g) = 8.35 x 10^23 g, Carbon: (0.25) * (1.67 x 10^24 g) = 4.18 x 10^23 g, Metals: (0.25) * (1.67 x 10^24 g) = 4.18 x 10^23 g, Silicon: (8.35 x 10^23 g) * ($1.00 $2.50 per kg) $1.67 x 10^24 $4.18 x 10^24, Carbon: (4.18 x 10^23 g) * ($1.00 $10.00 per kg) $4.18 x 10^23 $4.18 x 10^24, Metals: (4.18 x 10^23 g) * ($0.50 $1.50 per kg) $2.09 x 10^23 $6.26 x 10^23. A Dyson sphere is a theoretical megastructure that surrounds a star to collect its energy output. 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. 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. 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. Those include: Accelerating your swarm elements to orbital speed, which will probably be at least 0.05c. That part requires thinking beyond just the Dyson sphere and expanding to a Dyson swarm or bubble. 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 Additionally, the cost would depend on the specific design and capabilities of the drilling equipment required for the mission. They have been featured in science fiction books and TV shows including Star Trek. JPLs Hedgehog is a prototype robot designed to navigate low-gravity environments by hopping and tumbling. However, a Dyson swarm could be built relatively close to the event horizon, albeit at the massive cost of accelerating the individual satellites to near-light-speed to achieve orbit. Probably ONLY when you research the final tech, aka, Looping. Launch these components into space and gradually attach them to the Dyson sphere until it fully encloses the solar system. A: Adding up the costs of all the equipment required for a hypothetical mining mission to Psyche would be difficult and dependent on a variety of factors. I can think of another reason: use it as a. However, we can use current market prices as a rough estimate. Advanced civilizations would likely try to capture all the energy of their star to grow. [6] In 2013 Dyson said that he had come to regret that the concept had been named after him. TLDR 1: All useful energy comes from moving things from a low-entropy to high-entropy state, and doing something useful in the middle. Caroline Delbert is a writer, avid reader, and contributing editor at Pop Mech. "In this paper, we consider and discuss six types of energy sources: the CMB, the Hawking radiation, an accretion disk, Bondi accretion, a corona, and the relativistic jets from two types of black holes: a non-rotating black hole and a rotating black hole," the researchers explain. Because who have not tried to enter the Black Hole? Possible wavelengths for a hot Dyson Sphere to be detected in different black hole mass. In fictional accounts, the Dyson-sphere concept is often interpreted as an artificial, hollow sphere of matter around a star. What is amazing about this back and forth is that if I had to assemble the same set of answers together by doing a regular Google search or by constructing written sources, it would have taken me days, if not weeks, to do it. However, we've yet to even find traces of bacteria on another world, much less something this, well, epic in scale. rev2023.4.17.43393. One example of a PEM fuel cell that could be used for this application is the Ballard FCgen-H2PM fuel cell. Would accretion discs and the massive gravity well pulling in everything around you not be a worry, in the future? The estimated cost for a new Metal Bin ranges from $5,000 to $20,000, depending on the size and configuration. Alternately, you can think about an entire world powered by electric batteries instead of fossil fuels. I asked it a number of questions based on the technology, economics and material science aspects of building a giant structure like this and it answered all of them within reasonable bounds. What are major sources of these materials in the solar system? But is it at all feasible to use a black hole as you'd harness the energy of the sun or another star? Additionally, the cost would depend on the specific design and capabilities of the equipment required for the mission. How can I drop 15 V down to 3.7 V to drive a motor? Plan the mission: Based on the composition of the asteroid, a mining mission can be planned. Could you build a shell only a few thousand kilometers in diameter around a relatively small black hole, or would millions of kilometers be the minimum safe distance? 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. 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. However, there are some existing mining robots that could potentially be adapted for use on Psyche. Q: Ok, now lets see a few examples of relevant metal refining equipment and their approximate costs. Since you are asking, I would like to also give some information out of both interests and things that are to come. This is related to this question If the sphere surrounded a BH and used it as a heat dump (as well as extracting energy from it by dropping in mass) could its exterior be engineered to match the cosmic background temperature? The estimated cost for the Scarab project is around $1 million.

[1][24][25] Dyson spheres are depicted in the 19751983 book series Saga of Cuckoo by Frederik Pohl and Jack Williamson, and one functions as the setting of Bob Shaw's 1975 novel Orbitsville and its sequels. That we do not see them because managed BHs are the optimum places for high computation civilizations. Honestly. For example, Matrioshka brains have been proposed to extract energy for computation, while Shkadov thrusters would extract energy for propulsion. Q: What are some specific examples of drilling and mining robots that we can use? 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. 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. 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. Hsiao and his team thought first about stellar-mass black holes that form a binary system with a normal star. I must say I am enormously impressed. Q: Ok, now lets go back to building a Dyson sphere using metals and other materials from asteroids like Psyche. Language links are at the top of the page across from the title. Therefore, it's a theoretical device that sits around an entire star and harvests its energy. It uses a rotary-percussive drilling method and can drill up to one meter deep. If you built the sphere, at the optimum radial distance, then insulated the exterior as much as possible, would the gravitational redshift provide The most promising method for extracting metals from asteroids is likely to be a combination of mechanical and chemical processing. This is completely free of charge for everyone. Electrons etc cannot maintain their identity. Q: You assumed a radius of 1 AU in the calculation above. 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. I was aiming at a ball park estimate instead of an exact figure. [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]. 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. 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. I suggest asking about orbits near a BH on. The researchers conclude by showing what SETI should look for if a type 2 civilization is hypothetically using Dyson sphere technology to collect energy from in and around a black hole. Espaol - Latinoamrica (Spanish - Latin America). NASA RESOLVE drill: The Regolith and Environment Science and Oxygen Lunar Volatile Extraction (RESOLVE) drill is a prototype drilling system designed for extracting water and other resources from the Moon and other planetary bodies. Tungsten Tungsten is relatively rare in the solar system and is mainly found in the metallic cores of some of the largest asteroids and planets, such as Jupiter and Saturn. While this is the If a structure were to be built around the black holes event horizon, it would constantly be disturbed by falling matter, and it would have to be built to survive temperatures up to 2,700 degrees Celsius. We are hundreds of years out from such a feat if something like this is even possible. Transport the metals: Once the metals have been extracted, they need to be transported back to Earth or to a construction site for use in building the Dyson sphere. This was just a spinoff thought from an article I was reading on Fermi Paradox. 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. 2023 BDG Media, Inc. All rights reserved. Q: Ok. Lets go down the list of equipment one by one. New York, Iron (used instead of crude steel): $0.20 per kilogram. Q: I think you have made a mistake. The secret to this technique is to choose the right placelike the black hole's coronato collect energy. One example of an SOFC that could be used for this application is the Bloom Energy Server. Can you extract much energy by encapsulating the hole entirely? This short story is a fictional account of two very real people Anaximander and Anaximenes, two ancient Greeks who tried to make sense of the universe. Valve Corporation. A: Here are a few examples of storage and transportation equipment that could potentially be used for storing and transporting metals on Psyche, along with their estimated costs: Its worth noting that the cost of storage and transportation 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. This is significantly more than the estimated 4 x 10^20 kilograms of material that could be obtained from mining all of the asteroids in the solar system and the selected moons. Nothing with structural strength high enough exists, and it would require continual adjustment to not fall into the star/black hole. Q: What are the major sources of each of these metals in the solar system? Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. So if you think about (Boyajians) Star, and the way that it got dimmer and all of its weirdness [] That's the sort of thing they're looking for, more of those.. Visit our corporate site (opens in new tab). Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. 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. Ryugu: Ryugu is another carbonaceous asteroid that has been studied by the Japanese Hayabusa2 mission. Making statements based on opinion; back them up with references or personal experience. [8], SETI has looked for such infrared-heavy spectra from solar analogs, as has Fermilab. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. The estimated cost of a small modular reactor ranges from $500 million to $1 billion, depending on the design and capabilities. It would produce far more energy than even a normal Dyson Sphere. A solar-sized black hole (BH) has a diameter of about 6000 m. It's apparent area is then $$A' = 4\pi r^2 = 4 \pi ({3000}^2) = 1.1 \times 10^8 m^2$$. That's 20 times the data that Amazon Web Services holds, and it's effectively the storage backbone of the entire internet at the moment. Okay, so we have our two super freaky ideas. 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. Some of the metals that would be required include: These metals are just a few examples of the many different types of metals that would be required for building a Dyson sphere. on LinkedIn. 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. She's also an enthusiast of just about everything. 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. 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. 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. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. WebDyson Sphere Program Find A Black Hole#BlackHole #DysonSphereProgram The form of 'biosphere' which I envisaged con And that's challenging.. 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. All rights reserved. That'd be a very interesting feature to be included. A: Mining all the metal on Psyche would be a massive undertaking, requiring a significant amount of equipment and resources. 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. Vesta: Vesta is a large asteroid located in the asteroid belt that is thought to contain significant amounts of iron, nickel, and other minerals. A: You are correct, I apologize for the mistake in my previous response. What Lies Beneath the Ice of Jupiter's Moons? 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. Wow this is really cool! Outotecs Kaldo furnace is a rotary furnace used for smelting and refining various metals, including nickel, copper, and zinc. Waves break. However, these estimates should be taken with caution as they are based on current material prices and may not accurately reflect the cost of materials in the future, especially if they are required on a massive scale for such a large-scale project. Webb Space Telescope Image Shows Bright Galactic Collision, 2.29 billion years ago, This Cataclysmic Event Transformed the Makeup of Earths Crust. The Fermi Paradox, Explained. Dyson shell is (unfortunately) impossible to build. Orbits near a black hole are strange and dont follow Keplers laws, and things are more interesting with rotating BHs. While predominantly focused on the radio signals produced by an alien civilization, the problem becomes what happens if an alien civilization is not broadcasting them for reasons of self-preservation (i.e., you can't come and invade what you don't is there). .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. [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". 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. 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. The estimated cost of the Honeybee Robotics Planetary Deep Drill is not publicly available. I know it's a thought experiment now, but these are practical problems that must face any possible society capable of building these structures. If you truly want to understand modern astrophysics, knowing how to read this graph is essential. This method, they say, is more intensive than previous attempts to study black hole energy-harvesting, which have only explored the accretion disk (the structure of a black hole that you typically picture) or the cosmic microwave background (CMB), the electromagnetic radiation that remains from the earliest stages of the universe. Why is a "TeX point" slightly larger than an "American point"? Identify asteroids: The first step in asteroid mining is to identify suitable asteroids. And what Winterberg is saying is that something's got to give, like the wave nature of matter. The area around the black hole is extremely energetic, with its accretion disk accelerating matter so fast that it radiated energy for brighter than a star. Ganymede: Ganymede is the largest moon of Jupiter and is known to have significant deposits of various metals, including iron, nickel, and aluminum. That would almost certainly put them between a Type II and Type III civilization. Storage and transportation equipment: The refined metal would then need to be stored and transported to a construction site or to Earth. To absorb the accretion disc luminosity, a Dyson ring or a Dyson Swarm could be a How are small integers and of certain approximate numbers generated in computations managed in memory? Asking for help, clarification, or responding to other answers. The dyson sphere would have to be constructed in such a way that its mass was uniform in all directions done the planck length. How can I detect when a signal becomes noisy? @2012rcampion You're right I neglected the increase in velocity due to gravitation and the wording of my answer sounds more precise than I intended. 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. KelvinPlanck statement and entropy derivation. Titanium Titanium is a lightweight and strong metal that is also corrosion-resistant. In general, that'd be harder to detect, he says. 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. This would be a vast shell of energy collectors placed around a star to harvest its entire light output. Now if a star is inserted into the sphere, since the external radiation remains unchanged the surface of the DS must increase its temperature in order to radiate away the internally-generated heat.

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. Black holes feed on surrounding material from stars or other objects in its vicinity, and some of that material then shoots out in the form of two powerful jets. [9] Later searches also resulted in several candidates, all of which remain unconfirmed. 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. Black Hole 0.185 22900 1240 22 0.09590235397 O-type 2.165 22900 1240 257 Based on the updated calculations, constructing a Dyson sphere of this size and composition would require approximately 1.8 x 10^25 kilograms of material. A: Asteroid mining is a potential source of various metals that could be used for building a Dyson sphere around the solar system. The results depend on the assumptions put into the model, but this contraption could collect anywhere from hundreds to tens of thousands of times more energy. 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. Combining those challenges with the properties of a black hole gets even more tricky. The energy doesn't have 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). Not so (in any meaningful way) for the energy which is constantly being generated by the civilization which operates the DS. In the case of a solid body, the swallowing of mass has a cumulative effect. Valve Corporation. Here is a detailed plan for mining asteroids: In terms of which metals would be best to mine from asteroids for building a Dyson sphere, it would depend on a variety of factors, including the availability and concentration of the metals, as well as their usefulness in the construction of the Dyson sphere. The concept was later explored by the physicist Freeman Dyson in his 1960 paper "Search for Artificial Stellar Sources of Infrared Radiation". In the case of a civilization using power at solar system levels, the total power lost to the BH is $$P' = \eta \times P = 2\times 10^{-24} \times 3.8 \times 10^{26} = 7.6 \times 10^2$$ or 760 watts. What's the minimum safe distance to start building if you don't want any part of the shell or swarm to fall into the event horizon? What would it take to mine asteroids for procuring this material? It radiates a lot of energy. Honeybee Robotics Planetary Deep Drill: This is a lightweight, compact drill designed for deep drilling on other planets and asteroids. Converting all those hard X-rays to some form that's easier to transmit or store. The first modern imagining of such a structure was by Olaf Stapledon in his science fiction novel Star Maker (1937). The mission would involve sending a spacecraft to the asteroid to extract the desired metals. What could be better than a super freaky idea from the edges of astrophysics? What would the sky look like to a being inside the event horizon of a black hole? The purple, blue, green, orange, and red regions indicate X-ray(0.01 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. Give me a few examples of mining robots for mining metals on Psyche and their approximate cost. The main use of building a Dyson swarm around a black hole would be to capture the energy released by its accretion disk. Assuming a mix of 50% silicon, 25% carbon, and 25% metals by weight, the mass of each material required would be: As for the costs, the prices of raw materials can vary greatly depending on factors such as supply and demand, market conditions, and location. Additionally, the cost would depend on the specific design and capabilities of the refining equipment required for the mission. Can I ask for a refund or credit next year? And this current version 5.0 has been designed and deployed by Dumky de Wilde in collaboration with S. Abbas Raza. Medical equipment: Medical equipment for space missions needs to be lightweight, compact, and able to operate in microgravity. 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. If their maximum attainable velocity is one-half lightspeed, the dyson swarm units will be able to boost away from orbit around the back hole, if they need to (just think of it as an additional safety feature). 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. 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. , hollow sphere of matter powered by electric batteries instead of fossil fuels designed for deep on.
