While matter and energy that fall through the event horizon are lost, stuff that stays farther out can still radiate energy and escape. If the percentage of such atypical wavelengths were to be significant, an alien megastructure could be detected at interstellar distances. How can I detect when a signal becomes noisy? 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. Excuse me but isn't a Dyson swam supposed to collect light? 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. Since a blackbody radiates uniformly in all directions, the fraction of the energy emitted by any portion of the DS intercepted by the BH will simply be the BH area divided by half the area of DS. Why is a "TeX point" slightly larger than an "American point"? As for how your managed BH Dyson sphere might fare, have you ever seen a Chinese lantern catch fire? This is cosmic engineering - it will be a managed one. KelvinPlanck statement and entropy derivation. It could potentially be used on Psyche to explore the asteroids surface and collect data on the distribution of metal. Q: Would 4 x 10^20 kilograms of material be enough to construct a Dyson sphere that is 2 m thick, 2 AU from the sun and is 50% silicon, 30% carbon and 20% metals? Copper Copper is relatively rare in the solar system and is mainly found in the crusts of the rocky planets. 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. 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. Ganymede: Ganymede is the largest moon of Jupiter and is known to have significant deposits of various metals, including iron, nickel, and aluminum. 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). Orbits near a black hole are strange and dont follow Keplers laws, and things are more interesting with rotating BHs. Therefore, its unlikely that we would have enough material to construct a Dyson sphere of the size and composition you specified using only the asteroids and selected moons mentioned earlier. NOTE: This answer has limited itself to considering a possible minimum safe distance for a dyson swarm and not a dyson shell. It uses a bucket-wheel excavation method to excavate regolith and other materials. Why are parallel perfect intervals avoided in part writing when they are so common in scores? 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. 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 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. The energy doesn't have to be visible radiation - it can be anything output by the enclosed object.. The concept was later explored by the physicist Freeman Dyson in his 1960 paper "Search for Artificial Stellar Sources of Infrared Radiation". A: There are currently no mining robots specifically designed for mining metals on Psyche, as no such mission has yet been undertaken. : You cant pull energy out of a black hole, its physically imposible, just like you cant travel in time. For starters, its hard to imagine what even a Type I civilization would look like. Black holes can form at the center of stars in the Milky Way. 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). And that's challenging.. | by Gunnar De Winter | Predict | Medium 500 Apologies, but something went wrong on our But is it at all feasible to use a black hole as you'd harness the energy of the sun or another star? Because its smaller, the Penrose sphere will require far less material. Carnegie Mellons Scarab is a prototype robot designed to autonomously search for and collect mineral samples in extreme environments. If you built the sphere, at the optimum radial distance, then insulated the exterior as much as possible, would the gravitational redshift provided by the black hole not act to sort out your problem for you, if you want to dissipate it, as far as co-ordinate observers at any reasonable distance were concerned? 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. 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". Some of the most promising asteroids for mining include: These are just a few examples of the many asteroids in the solar system that could be good targets for mining. What are major sources of these materials in the solar system? The Dyson sphere is the ultimate end goal of the Dyson Sphere Program. Further out, it will be much simpler and easier, but require more materials" Why should there be an accretion disc? As the pencil falls, potential energy is being converted into kinetic energy. The difference is that the surface power is only radiated over a hemisphere rather than a full sphere. In the new paper, published earlier this summer in the Monthly Notices of the Royal Astronomical Society, the researchers ponder what it would take to power a type 2 or type 3 civilization, whose energy needs consume their entire solar system: How could Earth become a type 2 civilization? 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. And that's your homework! 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. How challenging? Solar panels are more effective on planets close the sun while swarms are more effective if the sun has high luminosity. 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.

Since Dyson's paper, many variant designs involving building an artificial structure or series of structures to encompass a star have been proposed in exploratory engineering or described in science fiction, often under the name "Dyson sphere". Additionally, the cost would depend on the specific design and capabilities of the drilling equipment required for the mission. 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. "An accretion disk, a corona, and relativistic jets could be potential power stations for a Type II civilization," the researchers write. Therefore, 4 x 10^20 kilograms of material would not be sufficient to construct a Dyson sphere of the size and composition you specified. The Environmental Control and Life Support System (ECLSS) used on the International Space Station costs around $250 million. 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. Give me a few examples of mining robots for mining metals on Psyche and their approximate cost. How much material would I need to build this Dyson sphere? 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. In principle, no, you cannot make a Dyson sphere which is indistinguishable from the CMB. Maybe have something that's mentioned in this video by Kurzgesagt? Can we create two different filesystems on a single partition. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. A black hole is a region of space with a gravitational pull so strong that nothing can escape its influence, not even light itself. In 2015, astronomer Tabetha Boyajian spotted a mysteriously dim star, its light flickering irregularly in a way that scientists had never observed before. A Type III civilization could combine them. Espaol - Latinoamrica (Spanish - Latin America). New external SSD acting up, no eject option. Orbits are not required for keeping rings or spheres in place. Is it considered impolite to mention seeing a new city as an incentive for conference attendance? 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? Search for Extra Terrestrial Intelligence (SETI), the world's billionaires venture outside of our planet, Your Privacy Choices: Opt Out of Sale/Targeted Ads, Extraterrestrials could use Dyson spheres to harvest.
