black hole dyson sphereblack hole dyson sphere
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. Determine the optimal distance from the sun at which to place the Dyson sphere. Excuse me but isn't a Dyson swam supposed to collect light? If we want to find extraterrestrials, we should follow their energy trail. This, they say, will likely be in the form of waste heat that we can observe with infrared spectrum technology. 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? Thanks for that. Some scientists believed that the star, officially known as KIC 8462852 but later dubbed Boyajians Star, had a Dyson sphere built around it, which resulted in its strange dimming. As the pencil falls, potential energy is being converted into kinetic energy. For a Dyson sphere thats at 2 AU and 2 meters thick, how many asteroids would we need to completely mine? What would be the rough cost of building this Dyson sphere? You're forgetting that the gravitational pull of the black hole will speed up the swarm units as they approach; as an example. Some examples of communication equipment that could be used for the mission include deep space antennas, transponders, and modems. Scientists believe that every major galaxy has a black hole lurking at its center. It has a drilling depth of up to 45 feet and a hole diameter of up to 12.25 inches. According to Tolkien, fantasy requires a deep imagination known as sub-creation. And the genre reflects a fundamental truth of being human. 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. Not three million, just three kilometres. This distance would need to be far enough away to avoid the intense heat and radiation of the sun, but close enough to capture a significant amount of its energy. It is believed to contain a variety of minerals and organic compounds, including water and amino acids. The estimated cost for the Scarab project is around $1 million. WebWhat if we could engineer a gigantic megastructure capable of harvesting every bit of the Sun's energy? How big a black hole is needed for this story? 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. You might need an entire planets worth of material, Wright says. 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. Q: You assumed a radius of 1 AU in the calculation above. Future US, Inc. Full 7th Floor, 130 West 42nd Street, 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. 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. The basic component is like a little brick, and we know how to build bricks to build solar panels and load them into space. Gear-obsessed editors choose every product we review. 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. Named by the CTA as a CES 2020 Media Trailblazer for his science and technology reporting, John specializes in all areas of computer science, including industry news, hardware reviews, PC gaming, as well as general science writing and the social impact of the tech industry. But constructing a sphere around a star sounds tricky enough civilizations would need materials that would not tear themselves apart or gravitationally attach themselves around any nearby objects. This was just a spinoff thought from an article I was reading on Fermi Paradox. Carnegie Mellons Scarab is a prototype robot designed to autonomously search for and collect mineral samples in extreme environments. 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. One example of a multi-junction solar cell that could be used for this application is the Boeing Spectrolab XTJ Prime. The next major revision was designed by S. Abbas Raza, building upon the earlier look, and coded byDumky de Wildein 2013. That part requires thinking beyond just the Dyson sphere and expanding to a Dyson swarm or bubble. 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. 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. It has a drilling depth of up to 5,000 meters and a hole diameter of up to 8 inches. The major sources of each of these metals in the solar system vary depending on the specific metal. 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. The secret to this technique is to choose the right placelike the black hole's coronato collect energy. 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. The first modern imagining of such a structure was by Olaf Stapledon in his science fiction novel Star Maker (1937). "Our results suggest that for a stellar-mass black hole, even at a low Eddington ratio, the accretion disk could provide hundreds of times more luminosity than a main sequence star.". Nickel Nickel is abundant in the metallic cores of the rocky planets and can also be found in asteroids and comets. The original site was designed by S. Abbas Raza in 2004 but soon completely redesigned by Mikko Hyppnen and deployed by Henrik Rydberg. Connect and share knowledge within a single location that is structured and easy to search. [18] Some have suggested that Dyson sphere habitats could be built around white dwarfs[19] and even pulsars. Dyson spheres have not been detected yet, but an advanced alien civilization would surely need them. However, we can use current market prices as a rough estimate. Extract the metals: There are several methods that could be used to extract metals from asteroids, including drilling, blasting, and crushing. How much farther? I'd suggest that "minimum" distance depends more upon the technology available to the builders than anything else. rev2023.4.17.43393. The estimated cost for the RASSOR project is around $3 million. And even if there are other civilizations, the technologies needed to create Dyson Spheres may be impossible. 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. The estimated cost for a new HIGmill ranges from $500,000 to $5 million, depending on the size and configuration. I overpaid the IRS. Q: Ok, now add up all these costs and give me an approximate number. The estimated cost of a small modular reactor ranges from $500 million to $1 billion, depending on the design and capabilities. @DirkBruere - In a .6 ly diameter Dyson sphere, a 6 km dia black hole radiation absorber is simply not going to make a difference. We are hundreds of years out from such a feat if something like this is even possible. Because its smaller, the Penrose sphere will require far less material. 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. No, I don't think so. 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. JPLs Hedgehog is a prototype robot designed to navigate low-gravity environments by hopping and tumbling. Q: Ok. Lets reduce the size of the Dyson sphere. Human support equipment: If humans were involved in the mining operation, specialized equipment would be needed to support their life in the harsh conditions of space. 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. On the other hand, pairs of particles, one particle and one antiparticle, separate due to the strong gravitational field whereby one gets inside the event horizon, and the other is emitted as radiation. When the pencil hits the floor this kinetic energy is dissipated, and you're left with a mass deficit. Should the alternative hypothesis always be the research hypothesis? 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. Take a look at Einstein saying light curves because the speed of light is spatially variable. New external SSD acting up, no eject option. because the speed of light is spatially variable, 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. Copyright 2007-2023 & BIG THINK, BIG THINK PLUS, SMARTER FASTER trademarks owned by Freethink Media, Inc. All rights reserved. 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? Q: Provide an estimate of the total amount of material we could get from completely mining all the asteroids in the solar system and also Io, Callisto, Ganymede, Europa and Mercury. What metals could best be mined from asteroids for our purpose? In 1960, physicist Freeman Dyson put forth a paper in Science that changed the way we talked about alien civilizations. Iron (used instead of crude steel): $0.20 per kilogram. 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. 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. Get counterintuitive, surprising, and impactful stories delivered to your inbox every Thursday. 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 Some way of starting a new system with your upgrades. Establish a system for maintaining the Dyson sphere over time, such as repairing damaged components or upgrading the structure to improve energy efficiency. [20], Stellar engines are hypothetical megastructures whose purpose is to extract useful energy from a star, sometimes for specific purposes. This material then forms a swirling disk of gas, known as an accretion disk, that spirals around the black hole and eventually passes through the event horizon. Which Exoplanets Are Likeliest to Host Alien Life? Theres also a possibility that a meteor or asteroid could nudge one of the pieces out of place. Outotecs Kaldo furnace is a rotary furnace used for smelting and refining various metals, including nickel, copper, and zinc. This obviously involves some pretty extreme astronomical engineering. Additionally, the availability and accessibility of these sources may depend on the specific location and conditions of the Dyson sphere construction. Alternately, you can think about an entire world powered by electric batteries instead of fossil fuels. Can a rotating object accelerate by changing shape? Quasars (opens in new tab), which are pretty much the energy being released in the immediate area around a supermassive black hole in the center of a galaxy, are the brightest objects in space, outshining all of the stars in the galaxy that contains them itself. Nassim Nicholas Taleb, author of Fooled by Randomness and The Black Swan. Scientists have upped the ante on theoretical Dyson Spheres with a proposal for alien civilizations constructing the colossal megastructures around stellar mass black holes, pushing the energy harvesting power well beyond what could be possible with just a traditional Dyson Sphere. Fuel cells: Fuel cells can also be used to generate power for remote operations. The estimated cost of RASSOR is $15 million. Click to load last save.". This would include satellite communication systems, GPS, and other navigation tools. 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. In 2015, astronomer Tabetha Boyajian spotted a mysteriously dim star, its light flickering irregularly in a way that scientists had never observed before. 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. Spheres detected in astronomical searches could be an indicator of extraterrestrial life. A Dyson sphere is a theoretical megastructure that surrounds a star to collect its energy output. 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. 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. Electrons etc cannot maintain their identity. 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. The main use of building a Dyson swarm around a black hole would be to capture the energy released by its accretion disk. In fictional accounts, the Dyson-sphere concept is often interpreted as an artificial, hollow sphere of matter around a star. 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. The questions I answered were simple, the answers complex. It has a drilling depth of up to 45 feet and a hole diameter of up to 12.25 inches. 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. I expect there would be neutrinos too, but it's still a pretty dramatic conversion of matter into energy. Because of the difference in the coordinate speed of light up here as opposed to down there. Earth, for instance, is a type 1 civilization under this rating system, because we only use the amount of energy available on our own planet. Put someone on the same pedestal as another. That's not how black holes work, and probably shouldn't work that way in the game. Gold: Gold is a highly conductive and corrosion-resistant metal that could be used in the construction of the Dyson spheres electrical components. Sandviks DE880 is a core drilling rig used for mineral exploration and geotechnical investigation. 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. 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. 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". But is it at all feasible to use a black hole as you'd harness the energy of the sun or another star? 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. She's also an enthusiast of just about everything. Q: Ok. Lets go down the list of equipment one by one. In principle, no, you cannot make a Dyson sphere which is indistinguishable from the CMB. 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. Finding valid license for project utilizing AGPL 3.0 libraries. 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. WebThey only spawn in small amounts, and only occur on planets orbiting neutron stars and black holes, and are only used for making Particle Container and the Plane Smelter . Ganymede: Ganymede is the largest moon of Jupiter and is known to have significant deposits of various metals, including iron, nickel, and aluminum. So the efficiency $\eta$ of the BH as an energy absorber is $$\eta = \frac{A'}{\frac{A}{2}} = \frac{1.1 \times 10^8}{.6\times 10^{32}} = 2\times 10^{-24}$$. Does Chain Lightning deal damage to its original target first? 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. The estimated cost for a new 797F is around $5 million. 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.
