black hole dyson sphereblack hole dyson sphere

Europa: Europa is another moon of Jupiter and is thought to have a subsurface ocean beneath its icy surface. If we want to find extraterrestrials, we should follow their energy trail. 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. In this way, a single black hole Dyson Sphere could put the beings that built it on a path to becoming a Type III civilization one with the capacity to collect the energy equivalent of an entire galaxy. Yes, that looks as if it works. We may earn commission if you buy from a link. You're forgetting that the gravitational pull of the black hole will speed up the swarm units as they approach; as an example.

Per the Stefan-Boltzmann Law, emitted power P is related to temperature T by $$P = \sigma T^4$$ where the Stefan-Boltzmann constant is $$\sigma = 5.6710^{8} W m^{2} K^{4}$$ We would need to consider other sources of material, such as mining other planets or moons in the solar system, or developing new methods for obtaining and processing materials. It was later upgraded extensively byDan Balisin 2006. [11][12][13], On 14 October 2015, Planet Hunters' citizen scientists discovered unusual light fluctuations of the star KIC 8462852 raising press speculation that a Dyson sphere may have been discovered. 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. Additionally, a mission to Psyche would likely require additional equipment for radiation shielding and protection from other hazards of deep space travel. What Happens When Two Black Holes Collide? The estimated cost for a new Metal Bin ranges from $5,000 to $20,000, depending on the size and configuration. If we improve the efficiency and reduce the cost of materials through technological developments a trend that has been the norm and not the exception throughout human history the timelines could be shorter. The major sources of each of these metals in the solar system vary depending on the specific metal. I wanted to see how efficiently chatGPT harnesses information from the internet to give me specifics and how well its large language model (LLM) of computation understood what I was saying. Electrons etc cannot maintain their identity. Doing that is really hard work because it isn't gravitationally stable. Lets describe them nevertheless. The questions I answered were simple, the answers complex. 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 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. 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. If such a megastructure could be constructed, it would significantly diminish the life of the star from our perspective, but would be lit up like Christmas lights in infrared. 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. 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? | by Gunnar De Winter | Predict | Medium 500 Apologies, but something went wrong on our According to Tolkien, fantasy requires a deep imagination known as sub-creation. And the genre reflects a fundamental truth of being human. Alternative ways to code something like a table within a table? It could also be used for mining operations on an asteroid, such as moving and manipulating mining equipment. Falling bodies do not slow down. While the hot material stays beyond the singularitys event horizon, it can emit energy that radiates away into space. How much farther? Since this is about 400,000 times the radius of the solar system (using the aphelion of Pluto as the marker - forget the Oort cloud for now), this suggests a pretty heroic structure, even by Dyson Sphere standards, and causes one to wonder exactly where the materials will come from. A Type III civilization could combine them. Okay, so we have our two super freaky ideas. This would require specialized refining equipment, such as smelters and chemical processing equipment. Ganymede: Ganymede is the largest moon of Jupiter and is known to have significant deposits of various metals, including iron, nickel, and aluminum. Alternately, you can think about an entire world powered by electric batteries instead of fossil fuels. Her favorite topics include nuclear energy, cosmology, math of everyday things, and the philosophy of it all. Estimates suggest that Mercurys crust may contain around 10^20 kilograms of metal, including significant amounts of iron and aluminum. This is only more vital if the energy source is a black hole rather than a traditional star. Robotics and automation equipment: Robotics and automation equipment can also be used for communication and navigation purposes, such as controlling mining and refining equipment remotely. 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. Would that give us enough material? It has a drilling depth of up to 45 feet and a hole diameter of up to 12.25 inches. That we do not see them because managed BHs are the optimum places for high computation civilizations. Orbits near a black hole are strange and dont follow Keplers laws, and things are more interesting with rotating BHs. Indeed, while a black hole may have huge gravity for its apparent 'size', a 20-solar-mass black hole has exactly the same gravity as a 20-solar-mass star. Install a network of mirrors and other devices to focus and redirect the suns energy towards the inhabited areas of the Dyson sphere. Dyson spheres all tie back to a system called the Kardashev scale, which is based on how much energy a civilization consumes. Honestly. It has a drilling depth of up to 45 feet and a hole diameter of up to 12.25 inches. The recent study suggests that instead of building a Dyson sphere around a star, a civilization can build the same megastructure around black holes. 2023 BDG Media, Inc. All rights reserved. TechRadar is part of Future US Inc, an international media group and leading digital publisher. Gold: Gold is a highly conductive and corrosion-resistant metal that could be used in the construction of the Dyson spheres electrical components. A black hole is a region of space with a gravitational pull so strong that nothing can escape its influence, not even light itself. Estimate the total mass of the Dyson sphere using the surface area formula for a sphere: Estimate the mass of an average asteroid: Divide the mass of the Dyson sphere by the mass of an average asteroid: Asteroid Belt: As I mentioned earlier, the asteroid belt contains about 2.8 x 10^21 kilograms of material. The wavelengths of such re-radiated energy may be atypical for the star's spectral type, due to the presence of heavy elements not naturally ocurring within the star. Q: Ok. Give me a detailed plan for mining asteroids for some of these metals. [9][10] Fermilab discovered 17 potential "ambiguous" candidates, of which four were in 2006 called "amusing but still questionable". A growing alien civilization may need to develop a way to harvest the energy of their host star. A solar-sized black hole (BH) has a diameter of about 6000 m. It's apparent area is then $$A' = 4\pi r^2 = 4 \pi ({3000}^2) = 1.1 \times 10^8 m^2$$. If you built the sphere, at the optimum radial distance, then insulated the exterior as much as possible, would the gravitational redshift provide How, then, could this civilization harvest the energy? Some way of starting a new system with your upgrades. Use MathJax to format equations. Additionally, the cost would depend on the specific design and capabilities of the storage and transportation equipment required for the mission. What metals could best be mined from asteroids for our purpose? While Dyson wasn't suggesting anything near what we now come to think of as a Dyson Sphere where a star is essentially encased in an artificial construct like a kind of stellar matryoshka doll the idea of something along these lines has captured the imaginations of the public and cosmologists alike. Even if we assume that all of this material is usable for constructing the Dyson sphere and that it has the desired composition of 50% silicon, 30% carbon, and 20% metals, it still wouldnt be enough to construct a Dyson sphere with a radius of 1 AU and a thickness of 1 meter. What would the sky look like to a being inside the event horizon of a black hole? 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. After a while there'll not be any matter to fall into it, unless you are providing it. 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. Extracting heat energy without a heat engine. The minimum safe distance for components of a dyson swarm will be determined by the maximum safe orbital velocity for the individual units of the swarm. Converting all those hard X-rays to some form that's easier to transmit or store. Further out, it will be much simpler and easier, but require more materials" 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. 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. The estimated cost for a new InLine Leach Reactor ranges from $500,000 to $1.5 million, depending on the size and configuration. RASSOR: The Regolith Advanced Surface Systems Operations Robot (RASSOR) is a mining robot designed for use on the Moon and other planetary bodies. Valve Corporation. Carnegie Mellons Scarab is a prototype robot designed to autonomously search for and collect mineral samples in extreme environments. Asking for help, clarification, or responding to other answers. 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. What would it take to mine asteroids for procuring this material? This would be a vast shell of energy collectors placed around a star to harvest its entire light output. Think of a Dyson Sphere is a very large building on a wall, Wright says. At current world GDP growth rates and assuming current prices, it would take about 600 years for us to have enough capital to build the sphere. If nothing else, it would be able to provide excellent starting points. Therefore, at the current world GDP growth rate of 2.5%, it would take approximately 572.5 years for world GDP to reach $6.117 x 10^33. And this current version 5.0 has been designed and deployed by Dumky de Wilde in collaboration with S. Abbas Raza. 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. "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.". I hope it is clear that the BH heat sinking has little effect on the energy balance of the DS. Don't forget the sphere would experience time dilation, so that's a factor. 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. Webb Space Telescope Image Shows Bright Galactic Collision, 2.29 billion years ago, This Cataclysmic Event Transformed the Makeup of Earths Crust. Black Holes store rotational energy that can be harnessed through magnetic reconnection and dropping material in to the ergosphere. 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. The energy doesn't have to be visible radiation - it can be anything output by the enclosed object.. A global coalition of scientists are in pursuit of the answer, analyzing six different types of energy that we could hypothetically harness from a black hole. Determine composition: Once a suitable asteroid has been identified, its composition needs to be determined. Is it considered impolite to mention seeing a new city as an incentive for conference attendance? 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? 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. This could be done using spacecraft or by launching the metals from the asteroids surface using a catapult-like device. Accretion disks also routinely produce high-energy beams, or jets, of plasma that rocket away from the disk and the Black Hole at velocities close to the speed of light. Dyson Spheres Around Black Holes: the Ultimate Energy Source? This means that a Penrose sphere is far smaller than a Dyson sphere encasing a star of equivalent mass. The estimated cost of a fuel cell system ranges from $500 to $1,000 per kilowatt, depending on the size and configuration. A: I apologize for the error in my previous response. The most promising method for extracting metals from asteroids is likely to be a combination of mechanical and chemical processing. This difference in speeds is precisely that referred to above by ceiling and floor observers. Titanium Titanium is relatively abundant in the solar system and is found in the crusts of the rocky planets, as well as in some asteroids and comets. Dysons based his proposal on the fact that a planet only receives a small fraction of the energy produced by its host star. Cimarrons Transloaders are mobile conveyor systems used for loading and unloading bulk materials. It is believed to contain water, carbon, and other minerals that could be valuable for space exploration and construction. Spacesuits: A high-quality spacesuit can cost anywhere from $2 million to $12 million. Crafting Recipes view source edit Show text recipes Crafting From 1 4s 10 2 1 5s 1 5 4 15 Categories Community content is available under CC-BY-SA unless otherwise noted. 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. That is exactly what we get from a new paper that explores how an advanced civilization might build a Dyson Sphere around a black hole to extract titanic amounts of energy. 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 Can I ask for a refund or credit next year? 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 perception is based on a literal interpretation of Dyson's original 1960 paper. If that is close enough to "insignificant", there is no need to go further. 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. And that's your homework! It has a drilling depth of up to 45 feet and a hole diameter of up to 12.25 inches. NOTE: This answer has limited itself to considering a possible minimum safe distance for a dyson swarm and not a dyson shell. Multi-junction solar cells: These are a type of solar cell that use multiple layers of semiconductor material to absorb a wider range of wavelengths of light, resulting in higher efficiency. Some examples of communication equipment that could be used for the mission include deep space antennas, transponders, and modems. Q: Ok, now lets see a few examples of relevant drilling equipment and their approximate costs. The calculation includes a number of approximations, but 600 years is a very short period of time based on astronomical and even civilizational timescales. Espaol - Latinoamrica (Spanish - Latin America), https://www.youtube.com/watch?v=ulCdoCfw-bY, https://journals.aps.org/prd/abstract/10.1103/PhysRevD.103.023014. However, its important to note that this is a very rough estimate and should not be taken as an accurate cost calculation. 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. One example of a multi-junction solar cell that could be used for this application is the Boeing Spectrolab XTJ Prime. A curvature of rays of light can only take place when the velocity [speed] of propagation of light varies with position". Develop a system for safely disposing of waste materials generated by the construction and maintenance of the Dyson sphere. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Put someone on the same pedestal as another. This can be done through remote sensing techniques, such as spectroscopy, which can provide information on the asteroids mineral composition. 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. Things that will actually happen in our time and are not added to the game, at least not to my awareness. We've got a long way to go before declaring anything we can't comprehend as impossible. The form of 'biosphere' which I envisaged con 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.. Estimates suggest that Ganymedes surface may contain around 5 x 10^18 kilograms of metal. Espaol - Latinoamrica (Spanish - Latin America). 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. 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. All that said, even though we imagine black holes as energy sinks rather than generators, that is not entirely the case. A relativistic Kessler cascade is going to be a horrible problem. GRBs don't happen for nothing. The next surrounding Dyson sphere would absorb this waste heat and use it for its computational purposes, all while giving off waste heat of its own. No clickbait, no fake news, not just entertainment, but depth and breadth something increasingly hard to find on the internet today. The issue seems almost well consigned to science fiction, but it is an important one when talking about the search for extraterrestrial intelligence (SETI).
