Thanks for that. Visit our corporate site (opens in new tab). Dysons assumption was that whether an advanced civilization signals its intelligence or hides it from us, it would not be able to hide the one thing thats essential for any civilization to grow energy. Possibly the energy gathering would need to be closer to the black hole than a Dyson sphere/swarm to a normal star which could cause difficulties though. Thanks for contributing an answer to Physics Stack Exchange! 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). No clickbait, no fake news, not just entertainment, but depth and breadth something increasingly hard to find on the internet today. 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. Is there a way to use any communication without a CPU? The basic component is like a little brick, and we know how to build bricks to build solar panels and load them into space. This would include spacesuits, life support systems, and medical equipment. Dyson proposed the spheres as a solution to a growing alien civilization needing a large enough energy output to sustain its existence. 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. Anything that crosses the event horizon is lost forever from our Universe. The secret to this technique is to choose the right placelike the black hole's coronato collect energy. If the percentage of such atypical wavelengths were to be significant, an alien megastructure could be detected at interstellar distances. Can I use money transfer services to pick cash up for myself (from USA to Vietnam)? This would require specialized storage containers and transportation equipment, such as spacecraft or cargo ships. Per the Stefan-Boltzmann Law, emitted power P is related to temperature T by $$P = \sigma T^4$$ where the Stefan-Boltzmann constant is $$\sigma = 5.6710^{8} W m^{2} K^{4}$$ Alternative ways to code something like a table within a table? Valve Corporation. If we were to mine asteroids, what kind of construction, human support, transportation and communication equipment would we need? 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. All rights reserved. WebWhat if we could engineer a gigantic megastructure capable of harvesting every bit of the Sun's energy? A: I apologize for the error in my previous response. Indeed, the paper, by T.Y. 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. Therefore, it's a theoretical device that sits around an entire star and harvests its energy. A: Sending all the equipment needed to mine Psyche would require a powerful and reliable launch vehicle capable of carrying a significant payload into deep space. Some way of starting a new system with your upgrades. Withdrawing a paper after acceptance modulo revisions? She's also an enthusiast of just about everything. The accretion disk is pretty hot. The composition of this material would include silicon, carbon and metals. These days, astronomers talk instead about Dyson Swarms dense arrays of orbiting energy collectors. Dyson shell is (unfortunately) impossible to build. 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. You might need an entire planets worth of material, Wright says. The estimated cost for a new A: Here are a few examples of metal refining equipment that could potentially be used for refining metals on Psyche, along with their estimated costs: Its worth noting that the cost of metal refining equipment for use on Psyche would likely be much higher than the above estimates, as the equipment would need to be specially designed and built to operate in the unique environment of an asteroid. The 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. Aliens Might Be Using Dyson Spheres to Harvest Energy From Black Holes, Scientists Say, A Dyson Sphere May Bring Humans Back From the Dead. But Wright suggests it might be exceedingly difficult. [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. For example, Matrioshka brains have been proposed to extract energy for computation, while Shkadov thrusters would extract energy for propulsion. It has a drilling depth of up to 45 feet and a hole diameter of up to 12.25 inches. It has a drilling depth of up to 1,000 meters and a hole diameter of up to 5 inches. Connect and share knowledge within a single location that is structured and easy to search. 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. 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 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. The specific types and amounts of metals needed would depend on the design and construction of the Dyson sphere, as well as the technologies and materials available at the time. Knock yourself out. [23], Fictional Dyson spheres are typically solid structures forming a continuous shell around the star in question, although Dyson himself considered that prospect to be mechanically implausible. Why is a "TeX point" slightly larger than an "American point"? @Innovine: I wasn't considering a rigid shell! :D, I wish I'll have some energy fraction gettable from previous spheres as well as a reward. 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. A: Here are a few examples of drilling equipment that could potentially be used for mining on Psyche, along with their estimated costs: Its worth noting that the cost of drilling equipment for use on Psyche would likely be much higher than the above estimates, as the equipment would need to be specially designed and built to operate in the unique environment of an asteroid. The second outlines impossibly dense regions of space and time surrounded by boundaries that separate their interiors from the rest of the cosmos. A Dyson sphere might be, say, the size of Earths orbit around the sun. For starters, its hard to imagine what even a Type I civilization would look like. How can I drop 15 V down to 3.7 V to drive a motor? 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 mission would involve sending a spacecraft to the asteroid to extract the desired metals. 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. Ryugu: Ryugu is another carbonaceous asteroid that has been studied by the Japanese Hayabusa2 mission. 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. Ganymede: Ganymede is the largest moon of Jupiter and is known to have significant deposits of various metals, including iron, nickel, and aluminum. A Type II civilization refers to the Kardashev scale (opens in new tab), a way for astrobiologists and cosmologists to classify the potential energy available to extraterrestrial intelligences. In fictional accounts, the Dyson-sphere concept is often interpreted as an artificial, hollow sphere of matter around a star. By creating a space-based structure, an alien civilization could meet the energy needs to push its civilization to the next level. Two Missions Will Investigate, Dazzling! Something's wrong. 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. 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. 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. Try two super freaky ideas from the edges of astrophysics. 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. Solar panels could be used to generate electricity on the asteroids surface, or a nuclear reactor could be used for continuous power generation. If we could disassemble both Jupiter and Mercury and also mine metal-rich asteroids and the major metal-rich moons of Jupiter and Saturn, we would get least 10^27 kilograms of material would be more than enough to build this sphere. 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. Additionally, the cost would depend on the specific design and capabilities of the power generation equipment required for the mission. Also note that gravity is not a force in the Newtonian sense. 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. 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. He speculated that this could be done via a system of structures orbiting the star, designed to intercept and collect its energy. If you want to understand what the Universe is, how it began, evolved, and will eventually end, astrophysics is the only way to go. 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. I was thinking of a radius of 2 AU. What would it take to mine asteroids for procuring this material? Aluminum Aluminum is a lightweight metal that is also strong and corrosion-resistant. Subscribe for free to Inverses award-winning daily newsletter! Black Holes store rotational energy that can be harnessed through magnetic reconnection and dropping material in to the ergosphere. It radiates a lot of energy. Webb Space Telescope Image Shows Bright Galactic Collision, 2.29 billion years ago, This Cataclysmic Event Transformed the Makeup of Earths Crust. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 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. 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. 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. Iron: Iron is one of the most abundant metals in the universe and could be used in the construction of the Dyson spheres structural components. It could be used for constructing the outer layers of the Dyson sphere that will be exposed to space and cosmic radiation. Could you build a stable structure just short of the Schwarzschild radius or would you need to move farther back to be safe? You probably think of a Dyson sphere as a structure that captures the sun's energy, but what would happen if you built one around a black hole instead? The estimated cost of a fuel cell system ranges from $500 to $1,000 per kilowatt, depending on the size and configuration. 2023 BDG Media, Inc. All rights reserved. The estimated cost of a star tracker ranges from $100,000 to $500,000, depending on the capabilities. 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. Sign up for a small monthly payment and enjoy ads-free browsing at 3QD, Make a one-time donation and enjoy ads-free browsing at 3QD. 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 for a new Metal Bin ranges from $5,000 to $20,000, depending on the size and configuration. Q: Ok, now lets see a few examples of relevant communication and navigation equipment and their approximate costs. What would the sky look like to a being inside the event horizon of a black hole? To absorb the accretion disc luminosity, a Dyson ring or a Dyson Swarm could be a It could be used for constructing the solar panels and for other parts of the Dyson sphere that require light, yet strong materials. In such pairings, the black hole pulls material away from the regular star. 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. Extract the metals: There are several methods that could be used to extract metals from asteroids, including drilling, blasting, and crushing. All that said, even though we imagine black holes as energy sinks rather than generators, that is not entirely the case. Q: Ok. Give me a detailed plan for mining asteroids for some of these metals. 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. Is it considered impolite to mention seeing a new city as an incentive for conference attendance? Number of asteroids required = Mass of Dyson sphere / Mass of average asteroid Number of asteroids required = 5.03 x 10^5 kg / 1.7 x 10^19 kg = 2.96 x 10^-14 asteroids. Additionally, the cost would depend on the specific design and capabilities of the robots required for the mission. Valve Corporation. Since, the game has black holes, so it would be interesting and awesome (in my opinion), if you could be able to build black hole energy gathering structures. One example of a PEM fuel cell that could be used for this application is the Ballard FCgen-H2PM fuel cell. Excuse me but isn't a Dyson swam supposed to collect light? A: Mining all the metal on Psyche would be a massive undertaking, requiring a significant amount of equipment and resources. All black hole measurements may look roughly alike, but there will be "abnormal peaks" on those that are likely housing Dyson sphere technologies, the scientists say. The main use of building a Dyson swarm around a black hole would be to capture the energy released by its accretion disk. In the longer term, consider the concept of uploading people's consciousnesses to some kind of data storage center, as proposed in an episode of the dystopian anthology series Black Mirror. [9] Later searches also resulted in several candidates, all of which remain unconfirmed. Language links are at the top of the page across from the title. The idea was later dismissed in favor of debris around the star, but it sparked a search for these megastructures. This, they say, will likely be in the form of waste heat that we can observe with infrared spectrum technology. Unexpected results of `texdef` with command defined in "book.cls". Can a black hole be turned into a white hole? It builds quickly and keeps every ray received in line of sight, and also makes the dyson sphere look like a giant Saturn. Nickel Nickel is abundant in the metallic cores of the rocky planets and can also be found in asteroids and comets. 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. Identify asteroids: The first step in asteroid mining is to identify suitable asteroids. It has a differentiated interior, which means that it has distinct layers of different materials, making it an interesting target for scientific exploration and mining. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. which is a just about $10^7$light-seconds, or 0.3 light-years. That's because the potential energy is mass-energy, in the pencil. [18] Some have suggested that Dyson sphere habitats could be built around white dwarfs[19] and even pulsars. The estimated cost for a new MT 5500AC is around $5 million. I flew into one, well as best as I could, it didn't do anything. Scientists have upped the ante on theoretical Dyson Spheres with a proposal for alien civilizations constructing the colossal megastructures around stellar mass black 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. Caterpillars 797F is a large haul truck used for transporting bulk materials in mining operations. This is just one of the many However, there are some existing mining robots that could potentially be adapted for use on Psyche. Making statements based on opinion; back them up with references or personal experience. 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. Install a network of mirrors and other devices to focus and redirect the suns energy towards the inhabited areas of the Dyson sphere. Q: Ok. Lets reduce the size of the Dyson sphere. This means that a Penrose sphere is far smaller than a Dyson sphere encasing a star of equivalent mass. Wormholes, yes, blackholes, no. If we were to completely disassemble Jupiter and Mercury and use all of their material for the Dyson sphere, it would provide an additional 1.901 x 10^27 kilograms of material, which would be more than enough to construct the Dyson sphere. ($10,00 quadrillion for Psyche sounded attractive, so I focused on Psyche). Therefore, it is likely that mining all known asteroids and the metal-rich moons of Jupiter and Saturn, as well as completely disassembling Jupiter and Mercury, would provide enough material to construct a Dyson sphere that is 1 m thick, 1 AU from the sun, and has a composition of 50% silicon, 30% carbon, and 20% metals.
