black hole dyson sphereblack hole dyson sphere

I suppose I should ask, but it's psychology not physics, why would a society that can build a DS be worried about other people/aliens noticing them:) A managed accretion disc would end your energy worries for a long time, hadn't thought of that aspect. Estimates suggest that Mercurys crust may contain around 10^20 kilograms of metal, including significant amounts of iron and aluminum. I overpaid the IRS. Wow this is really cool!

Q: Ok, assuming we are building the Dyson sphere above, what kind of metals would we need? After all, dont black holes swallow everything that falls into the event horizon, including light? 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. Determine composition: Once a suitable asteroid has been identified, its composition needs to be determined. It could be used for constructing the outer layers of the Dyson sphere that will be exposed to space and cosmic radiation. This energy-capturing sphere would radiate its enormous waste heat out in the infrared spectrum. It could potentially be used on Psyche to explore the asteroids surface and collect data on the distribution of metal. Q: Ok, now lets see a few examples of relevant drilling equipment and their approximate costs. Based on the calculations I provided earlier, constructing a Dyson sphere of this size and composition would require approximately 9.1 x 10^25 kilograms of material. [9][10] Fermilab discovered 17 potential "ambiguous" candidates, of which four were in 2006 called "amusing but still questionable". Spellcaster Dragons Casting with legendary actions? $\begingroup$ Building a Dyson sphere is about capturing energy output and using that to power to run the civilisation inhabiting the sphere. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Originally, the scale numbered from I to III, with Type I being a civilization capable of harnessing all of the energy of their home planet (humanity isn't even close to this stage yet). answer to the above: construct the swarm to be inclusive of a repulsive gravitational field (similar the the astrophysical structure of a pulsar) oscillated/emitted from the swarm itself to sustain around the hole, additionally have each equipped with a laser based projection optical ray to catalyze the accretion disk for higher power achievement through absorption by the swarm. [9] Later searches also resulted in several candidates, all of which remain unconfirmed. In principle, no, you cannot make a Dyson sphere which is indistinguishable from the CMB. The reason is fairly simple. Let's start with a blackbody [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. What would be its composition? The second outlines impossibly dense regions of space and time surrounded by boundaries that separate their interiors from the rest of the cosmos. Silicon, carbon, and metals are likely to be among the most commonly used materials. The estimated cost of a robotic arm ranges from $1 million to $5 million, depending on the capabilities. The estimated cost for a new InLine Leach Reactor ranges from $500,000 to $1.5 million, depending on the size and configuration. Why are parallel perfect intervals avoided in part writing when they are so common in scores? I think it's essentially correct. [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. The estimated cost for the Scarab project is around $1 million. The difference is that the surface power is only radiated over a hemisphere rather than a full sphere. TLDR 1: All useful energy comes from moving things from a low-entropy to high-entropy state, and doing something useful in the middle. Solar panels are more effective on planets close the sun while swarms are more effective if the sun has high luminosity. rev2023.4.17.43393. Is a copyright claim diminished by an owner's refusal to publish? Orbits are not required for keeping rings or spheres in place. Q: What are the major sources of each of these metals in the solar system? A: Asteroid mining is a potential source of various metals that could be used for building a Dyson sphere around the solar system. We Know How Fast Earth Spins Dont We? 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. 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. NASAs RASSOR (Regolith Advanced Surface Systems Operations Robot) is a lunar mining robot that was developed to excavate and transport lunar regolith. 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. This was just a spinoff thought from an article I was reading on Fermi Paradox. Take a look at Einstein saying light curves because the speed of light is spatially variable. Additionally, the cost would depend on the specific design and capabilities of the storage and transportation equipment required for the mission. Not three million, just three kilometres. Yes, but a sphere surrounding a BH has a central sink at effectively 0 degK. Some examples of navigation equipment that could be used for the mission include star trackers, gyroscopes, and accelerometers. However, these estimates should be taken with caution as they are based on current material prices and may not accurately reflect the cost of materials in the future, especially if they are required on a massive scale for such a large-scale project. Gold: Gold is a highly conductive and corrosion-resistant metal that could be used in the construction of the Dyson spheres electrical components. In such pairings, the black hole pulls material away from the regular star. From this you can calculate that, at 2.75 K, the emitted power of a black body is about 3.2 $\mu$W /$m^2$. Older adults who napped at least once or for more than an hour a day had a40% higher chanceof developing Alzheimers than those who napped less. Scientists believe that every major galaxy has a black hole lurking at its center. Protect a planet against a black hole attack. What Happens When Two Black Holes Collide? The secret to this technique is to choose the right placelike the black hole's coronato collect energy. 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. Hsiao and his team thought first about stellar-mass black holes that form a binary system with a normal star. It has a drilling depth of up to 45 feet and a hole diameter of up to 12.25 inches. 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. The dyson sphere would have to be constructed in such a way that its mass was uniform in all directions done the planck length. New external SSD acting up, no eject option. 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? 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. 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? Black holes make better engines for Dyson Spheres than stars. It is estimated to be worth over $10,000 quadrillion, making it one of the most valuable objects in the solar system. (We need a theory of quantum gravity to really understand what happens at the singularity.) The estimated cost for a new DE880 is around $1.5 million. It could be used for constructing the solar panels and for other parts of the Dyson sphere that require light, yet strong materials. To absorb the accretion disc luminosity, a Dyson ring or a Dyson Swarm could be a 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. Use MathJax to format equations. WebA solar-sized black hole (BH) has a diameter of about 6000 m. It's apparent area is then A = 4 r 2 = 4 ( 3000 2) = 1.1 10 8 m 2 Since a blackbody radiates uniformly in all The Environmental Control and Life Support System (ECLSS) used on the International Space Station costs around $250 million. See this 2001 paper by Friedwardt Winterberg. The estimated cost for a new Transloader ranges from $200,000 to $500,000, depending on the size and configuration. 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. We've only been able to detect the presence of a few thousand exoplanets around alien stars. Under the right conditions, the matters self-gravity overwhelms everything else, leading it to collapse into what we call a singularity where all the mass gathers in a single geometric point. The results depend on the assumptions put into the model, but this contraption could collect anywhere from hundreds to tens of thousands of times more energy. Nassim Nicholas Taleb, author of Fooled by Randomness and The Black Swan. Visit our corporate site (opens in new tab). It has a drilling depth of up to 1,000 meters and a hole diameter of up to 5 inches. The estimated cost of the Honeybee Robotics Planetary Deep Drill is not publicly available. Would 4 x 10^20 kilograms of material be enough to construct a Dyson sphere that is 1 m thick, 1 AU from the sun and is 50% silicon, 30% carbon and 20% metals? Can we create two different filesystems on a single partition. on Twitter, Share Could aliens suck the energy from black holes with Dyson Spheres? 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. 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. Would that give us enough material? The estimated cost of a fuel cell system ranges from $500 to $1,000 per kilowatt, depending on the size and configuration. Valve Corporation. The recent study suggests that instead of building a Dyson sphere around a star, a civilization can build the same megastructure around black holes. Using current telescopes such as the Galaxy Evolution Explorer, an orbiting space telescope launched in 2003, the authors argue that one could detect such structure around a distant star. Possible wavelengths for a hot Dyson Sphere to be detected in different black hole mass. That's not how black holes work, and probably shouldn't work that way in the game. Q: Ok, now lets see a few examples of relevant power generation equipment and their approximate costs. WebDyson Sphere Program Find A Black Hole#BlackHole #DysonSphereProgram which is a just about $10^7$light-seconds, or 0.3 light-years. Additionally, the cost would depend on the specific design and capabilities of the equipment required for the mission. You're forgetting that the gravitational pull of the black hole will speed up the swarm units as they approach; as an example. The natural follow-up question is why we'd need that much energy in the first place. All trademarks are property of their respective owners in the US and other countries. Withdrawing a paper after acceptance modulo revisions? 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. Which Exoplanets Are Likeliest to Host Alien Life? 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. I shall edit my answer accordingly. 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. The estimated cost for a new Kaldo furnace is around $10 million. It could be used for the framework and support structure of the Dyson sphere. Thanks for contributing an answer to Physics Stack Exchange! The first describes vast, solar system-sized machines surrounding a star and built by a hyper-advanced civilization to harvest energy. It uses a rotary-percussive drilling method and can drill up to one meter deep.
