George Dvorsky has advocated the use of self-replicating robots to overcome this limitation in the relatively near term. 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. Indeed, the paper, by T.Y. However, here is a rough estimate of the costs of some of the equipment we have discussed: Overall, its possible that the total cost of the equipment required for a mining mission to Psyche could be in the range of several billion dollars. More information: Tiger Yu-Yang Hsiao et al, A Dyson sphere around a black hole, Monthly Notices of the Royal Astronomical Society (2021). Advanced civilizations would likely try to capture all the energy of their star to grow. 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? [9][10] Fermilab discovered 17 potential "ambiguous" candidates, of which four were in 2006 called "amusing but still questionable". MathJax reference. The main use of building a Dyson swarm around a black hole would be to capture the energy released by its accretion disk. Estimates suggest that Europas surface may contain around 10^17 kilograms of water ice, as well as significant amounts of other volatiles such as carbon dioxide and sulfur dioxide. Not three million, just three kilometres. Iron (used instead of crude steel): $0.20 per kilogram. What is the difference between these 2 index setups? The most promising method for extracting metals from asteroids is likely to be a combination of mechanical and chemical processing. 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. :D, I wish I'll have some energy fraction gettable from previous spheres as well as a reward. What would it take to mine asteroids for procuring this material? This energy-capturing sphere would radiate its enormous waste heat out in the infrared spectrum. I expect there would be neutrinos too, but it's still a pretty dramatic conversion of matter into energy. Vesta: Vesta is a large asteroid located in the asteroid belt that is thought to contain significant amounts of iron, nickel, and other minerals. Finding valid license for project utilizing AGPL 3.0 libraries. Estimates suggest that Ganymedes surface may contain around 5 x 10^18 kilograms of metal. However, even if we were able to completely disassemble these planets and use all of their material, its still unlikely that we would have enough material to construct a Dyson sphere of the size and composition you specified. Is a copyright claim diminished by an owner's refusal to publish? New York, 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. 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. $6.117 x 10^33 = $85 trillion x (1 + 0.025)^n, (1 + 0.025)^n = ($6.117 x 10^33) / ($85 trillion). It would produce far more energy than even a normal Dyson Sphere. 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. WebA black hole with the same mass has a diameter of under three. 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. 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. 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. Don't forget the sphere would experience time dilation, so that's a factor. Subscribe for free to Inverses award-winning daily newsletter! Electrons etc cannot maintain their identity. We orbit at a distance of 93 million miles (about 150 million km). Espaol - Latinoamrica (Spanish - Latin America). I am copying my exchange with chatGPT below in its entirety to give readers an idea of the level of detail it can bring to the conversation. 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. Falling bodies do not slow down. This would require specialized refining equipment, such as smelters and chemical processing equipment. anyway the smallest stellar black hole would be at least above 3 solar masses so either depends on your mass a stable orbit without artificial acceleration is given by Force(net) equal to (Mass(1 swarm) multiply by velocity square) divided by distance. This could be done using spacecraft or by launching the metals from the asteroids surface using a catapult-like device. Alternately, you can think about an entire world powered by electric batteries instead of fossil fuels. The estimated cost of the RESOLVE drill is $10 million. The concept was later explored by the physicist Freeman Dyson in his 1960 paper "Search for Artificial Stellar Sources of Infrared Radiation". 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. Terexs MT 5500AC is a haul truck used for transporting bulk materials in mining operations. 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. We Know How Fast Earth Spins Dont We? Learn more about Stack Overflow the company, and our products. A: You are correct, I apologize for the mistake in my previous response. 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. [14][15] However, subsequent analysis showed that the results were consistent with the presence of dust. In "San Junipero," two young women meet and fall in love from inside a server farm, while their bodies exist in vegetative states in the real world. 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. Combining those challenges with the properties of a black hole gets even more tricky. "An accretion disk, a corona, and relativistic jets could be potential power stations for a Type II civilization," the researchers write. Solar panels could be used to generate electricity on the asteroids surface, or a nuclear reactor could be used for continuous power generation. It has a drilling depth of up to 5,000 meters and a hole diameter of up to 8 inches. Copper Copper is a good conductor of electricity and could be used for wiring and electrical components of the Dyson sphere. Stand on a chair and drop a pencil. If nothing else, it would be able to provide excellent starting points. Theres also a possibility that a meteor or asteroid could nudge one of the pieces out of place. 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. Tungsten: Tungsten is a very hard and dense metal that could be used in the construction of the Dyson spheres high-temperature components, such as lighting filaments and electrical contacts. Titanium Titanium is a lightweight and strong metal that is also corrosion-resistant. 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. Q: Ok, now lets see a few examples of human support equipment equipment and their approximate costs. 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. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Can a black hole be turned into a white hole? 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. Since then these giant spheres later sometimes imagined as distributed panels rather than single continuous shells that can be constructed by advanced civilizations to capture their stars energy have become known as Dyson spheres. Hearst Magazine Media, Inc. All Rights Reserved. However, its important to note that this is a very rough estimate and should not be taken as an accurate cost calculation. Design the Dyson sphere to be modular, allowing for individual components to be assembled in space and gradually added to the structure over time. it would have been funnier if you get close, and the gravity is so strong you cannot fight it, get sucked in and it says, "Game Over. EDIT It's true that this has so far ignored the black hole, and there is a very good reason - a black hole is very small, particularly compared to the DS. Io: Io is one of the moons of Jupiter and is known to have a high concentration of sulfur and other volatiles on its surface. Doing that is really hard work because it isn't gravitationally stable. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. It radiates a lot of energy. We've only been able to detect the presence of a few thousand exoplanets around alien stars. 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. So the efficiency $\eta$ of the BH as an energy absorber is $$\eta = \frac{A'}{\frac{A}{2}} = \frac{1.1 \times 10^8}{.6\times 10^{32}} = 2\times 10^{-24}$$. It is believed to contain water, carbon, and other minerals that could be valuable for space exploration and construction. But let's run the numbers anyways. Q: At current world GDP growth rates, how long would it take for world GDP to reach $6.117 x 10^33? A Dyson sphere might be, say, the size of Earths orbit around the sun. The mission would involve sending a spacecraft to the asteroid to extract the desired metals. In general, that'd be harder to detect, he says. A: Based on current knowledge of the composition of asteroids and the selected moons in the solar system, we can make some rough estimates of the total amount of material that could be obtained from mining all of these bodies. Dyson speculated that such structures would be the logical consequence of the escalating energy needs of a technological civilization and would be a necessity for its long-term survival. In response to letters prompted by some papers, Dyson replied, "A solid shell or ring surrounding a star is mechanically impossible. [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]. What would the sky look like to a being inside the event horizon of a black hole? This would include spacesuits, life support systems, and medical equipment. How Well Build the First Roads on the Moon, Why These 6 Newfound Galaxies Make No Sense, Wormholes Can Magnify Light By a Factor of 100,000, In Just 10 Years, We Could Start Mining the Moon, Turns Out, the Moon Is WAY Younger Than We Thought, Is Anyone Out There? It is estimated to be worth over $10,000 quadrillion, making it one of the most valuable objects in the solar system. Anything that crosses the event horizon is lost forever from our Universe. He also proposed that nascent search for extraterrestrial intelligence (SETI) programs should search for sources of infrared radiation to accompany the recently initiated search for interstellar radio communications.. They would then move to harness the energy of its host star more directly by constructing platforms around their star in a form of biosphere that would absorb most of the star's energy. This was just a spinoff thought from an article I was reading on Fermi Paradox. Two Missions Will Investigate, Dazzling! In 1960, physicist Freeman Dyson put forth a paper in Science that changed the way we talked about alien civilizations. The EMU has been used on the International Space Station and the Space Shuttle and costs around $12 million. I suggest asking about orbits near a BH on. 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. Mercury: Mercury is the smallest planet in the solar system and is known to have a high concentration of metals in its crust. 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. If Fine Structure Constant in not uniform in space what would that imply for cosmic background? Even as this advanced alien civilization soaked up all that energy, they could not help but bleed off excess heat into space, lest their platforms melt entirely. Solar panels are more effective on planets close the sun while swarms are more effective if the sun has high luminosity. I think it's essentially correct. A black hole forms when a large enough collection of mass comes together in a small enough space. Type II civilizations would be capable of harnessing all of the energy produced by its host star, with Type III being able to harness the entire energy of a galaxy. Why is a "TeX point" slightly larger than an "American point"? Based on estimates from the Galileo mission, its been suggested that Ios surface may contain around 10^18 kilograms of sulfur. 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. It could potentially be used on Psyche to explore the asteroids surface and collect data on the distribution of metal. The swarm could be made of many individual collectors placed all around the different parts of a black hole in order to best collect from the accretion disk, the corona, and the relativistic jets. Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. WebBlack Hole Dyson Sphere TIMELAPSE | Dyson Sphere Program Nilaus 169K subscribers 321K views 1 year ago #DysonSphere #Factorio #LetsPlay TIMELAPSE No voice. Iron Iron is a common construction material due to its strength, durability, and abundance. [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. If the percentage of such atypical wavelengths were to be significant, an alien megastructure could be detected at interstellar distances. Also see Shapiro, and this Baez article: Einstein talked about the speed of light changing in his new theory. If space vehicles can accelerate to whatever their maximum velocity is, they will also have the capacity to decelerate too. Give me a few examples of mining robots for mining metals on Psyche and their approximate cost. In fictional accounts, the Dyson-sphere concept is often interpreted as an artificial, hollow sphere of matter around a star. 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. Black Holes store rotational energy that can be harnessed through magnetic reconnection and dropping material in to the ergosphere. Some of the questions I asked chatGPT included: I verified at least some (but not all) of the numbers it gave me from other sources and was finally able to arrive at the following conclusion: Building a 1 meter thick Dyson sphere at 1 AU from the sun would take approximately 10^25 kilograms of material. The estimated cost of the HRF is not publicly available. 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. Gear-obsessed editors choose every product we review. Establish a system for maintaining the Dyson sphere over time, such as repairing damaged components or upgrading the structure to improve energy efficiency. Perhaps if they introduced a wormhole, then yeah, this would be pretty neat. Black Hole 0.185 22900 1240 22 0.09590235397 O-type 2.165 22900 1240 257 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. All rights reserved. Aliens Might Be Using Dyson Spheres to Harvest Energy From Black Holes, Scientists Say, A Dyson Sphere May Bring Humans Back From the Dead. 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. Keeping space fairly clear of debris in the area. This would include satellite communication systems, GPS, and other navigation tools. 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. 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. 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. Why hasn't the Attorney General investigated Justice Thomas? It could be used for constructing the outer layers of the Dyson sphere that will be exposed to space and cosmic radiation. 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". Using that radiation and the radiation of the accretion disc, there is a lot of potential energy swarming around a black hole. 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. 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. Jupiter, for example, has a mass of approximately 1.898 x 10^27 kilograms, while Mercury has a mass of approximately 3.285 x 10^23 kilograms. 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). Black holes can form at the center of stars in the Milky Way. 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. which is a just about $10^7$light-seconds, or 0.3 light-years. or at least your mech upgrades. 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. The second outlines impossibly dense regions of space and time surrounded by boundaries that separate their interiors from the rest of the cosmos. The idea was later dismissed in favor of debris around the star, but it sparked a search for these megastructures. Q: Ok, now lets see a few examples of relevant storage and transportation equipment and their approximate costs. 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. Outotecs Kaldo furnace is a rotary furnace used for smelting and refining various metals, including nickel, copper, and zinc. Now, I realize that last sentence is pretty wild. Why? Sandviks DE880 is a core drilling rig used for mineral exploration and geotechnical investigation. I flew into one, well as best as I could, it didn't do anything. Get counterintuitive, surprising, and impactful stories delivered to your inbox every Thursday. 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. If you built the sphere, at the optimum radial distance, then insulated the exterior as much as possible, would the gravitational redshift provide This is the point at which an Earth far into the future might need to harness the full power of the sun, and the point at which we'd become a Kardashev type 2 civilization. Nothing with structural strength high enough exists, and it would require continual adjustment to not fall into the star/black hole. These structures became known as Dyson spheres, and a handful of programs have sought them out by looking for weird infrared signatures around neighboring stars. Click to load last save.". 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. A relativistic Kessler cascade is going to be a horrible problem. But by analyzing what such an object would look like and leave behind as excess heat, scientists are better able to search the cosmos for that signatureand find any new neighbors who are running Dyson spheres on their nearest black hole. SteelFabs Metal Bins are storage containers used for storing and transporting bulk materials. The estimated cost for a new DM30 II is around $1.5 million. 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. What would be the rough cost of building this Dyson sphere? All trademarks are property of their respective owners in the US and other countries. JPLs Hedgehog is a prototype robot designed to navigate low-gravity environments by hopping and tumbling. Fictional depictions often describe a solid shell of matter enclosing a star an arrangement considered by Dyson himself to be implausible. You would probably have to ground up whole planets just to get the material you need. 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. I am reviewing a very bad paper - do I have to be nice? Q: Ok. Give me a detailed plan for mining asteroids for some of these metals. It uses a bucket-wheel excavation method to excavate regolith and other materials. 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. 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. Dyson's answer is the Dyson sphere, or "a hollow ball built around the sun [that] would solve the space and energy problems," according to his paper. 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. In it, Dyson conjectured that a sufficiently advanced civilization would harness the power of its home star to generate power on a massive scale. Yes, that looks as if it works. A: Building a Dyson sphere around the entire solar system is a hypothetical and incredibly complex engineering feat that would require technology far beyond our current capabilities. A Type II civilization would have to be thousands of years beyond even that high threshold, and considering the incredibly unlikelihood of life developing on a planet orbiting a stellar mass black hole, much less one surviving long enough to achieve Type I status, any civilization building a Dyson Sphere around a stellar-mass black hole would have to travel from their host star to that black hole and construct one. Penn State Extraterrestrial Intelligence Center. Poof, gone. Should a civilization this advanced exist, then they would probably already know of our existence by the time we discover the black hole Dyson sphere. 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. She's also an enthusiast of just about everything. Give me some details on the kind of rocket or launch vehicle that would work. They have been featured in science fiction books and TV shows including Star Trek. 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-lightspeed to achieve orbit. But, the galaxy is an immense place with an estimated 400 billion stars in it. 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. They suffer a form of annihilation, and the result is a gamma ray burst. The estimated cost for a new DE880 is around $1.5 million.
