black hole dyson sphere

Some examples of navigation equipment that could be used for the mission include star trackers, gyroscopes, and accelerometers. The estimated cost of a robotic arm ranges from $1 million to $5 million, depending on the capabilities. Scientists have upped the ante on theoretical Dyson Spheres with a proposal for alien civilizations constructing the colossal megastructures around stellar mass black In 1960, physicist Freeman Dyson put forth a paper in Science that changed the way we talked about alien civilizations. How much material would I need to build this Dyson sphere? [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. can one turn left and right at a red light with dual lane turns? Something's wrong. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. rev2023.4.17.43393. A: Sending all the equipment needed to mine Psyche would require a powerful and reliable launch vehicle capable of carrying a significant payload into deep space. Power generation equipment: To power the mining and refining equipment, a source of energy would be needed. 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 Once the equipment arrived at Psyche, it would need to be carefully deployed and assembled on the asteroids surface or in orbit around the asteroid, depending on the specific mining plan. In addition, Io is thought to have significant deposits of iron, nickel, and other metals, although the exact amounts are uncertain. [2][3] They are sometimes used as the type of plot device known as a Big Dumb Object. 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. Additionally, the cost would depend on the specific design and capabilities of the robots required for the mission. Additionally, the cost would depend on the specific design and capabilities of the storage and transportation equipment required for the mission. The reason is fairly simple. 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. I expect there would be neutrinos too, but it's still a pretty dramatic conversion of matter into energy. Earth is far from using a Dyson sphere to harvest our sun, Jupiter, or even a black hole. The mission would involve sending a spacecraft to the asteroid to extract the desired metals. Learn more about Stack Overflow the company, and our products. 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. The SLS will use a combination of liquid hydrogen and liquid oxygen fuel to power its engines, and it will be able to launch both crewed and uncrewed missions. 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. 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 If you're a Type II civilization, you'd get far more bang from your investment building a Dyson Sphere around a black hole than a typical main sequence star. 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 go back to building a Dyson sphere using metals and other materials from asteroids like Psyche. The estimated cost of a small modular reactor ranges from $500 million to $1 billion, depending on the design and capabilities. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Lets unpack things a bit. 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. That problem was what inspired physicists Freeman Dyson to postulate in 1960 that a sufficiently advanced alien race would reach the point where its energy needs exceeded what its planet was capable of supplying. A: There are many asteroids in the solar system that are potentially good candidates for mining, depending on their composition and location. Thermodynamically possible to hide a Dyson sphere? Since you are asking, I would like to also give some information out of both interests and things that are to come. I was aiming at a ball park estimate instead of an exact figure. Please fill out the form below to get our email with all the posts from the previous 24 hours, which is sent out a bit after midnight (NY City time) each day. Black holes make better engines for Dyson Spheres than stars. What Lies Beneath the Ice of Jupiter's Moons? Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. How, then, could this civilization harvest the energy? Per the Stefan-Boltzmann Law, emitted power P is related to temperature T by $$P = \sigma T^4$$ where the Stefan-Boltzmann constant is $$\sigma = 5.6710^{8} W m^{2} K^{4}$$ 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. In such pairings, the black hole pulls material away from the regular star. Blackholes don't work like this. 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. Also see Shapiro, and this Baez article: Einstein talked about the speed of light changing in his new theory. The estimated cost of solar panels ranges from $0.30 to $0.50 per watt, depending on the type and efficiency of the panel. WebThe innermost Dyson sphere of the Matrioshka brain would draw energy directly from the star it surrounds and give off large amounts of waste heat while computing at a high temperature. The choice of asteroid would depend on a variety of factors, including its composition, location, and accessibility, as well as the cost and technology required to extract and transport the desired materials. This can be done through remote sensing techniques, such as spectroscopy, which can provide information on the asteroids mineral composition. More information: Tiger Yu-Yang Hsiao et al, A Dyson sphere around a black hole, Monthly Notices of the Royal Astronomical Society (2021). I overpaid the IRS. Now, all of this is obviously the purest of pure speculation. A: I apologize for the error in my previous response. @DirkBruere - In a .6 ly diameter Dyson sphere, a 6 km dia black hole radiation absorber is simply not going to make a difference. 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. Sign up to receive daily breaking news, reviews, opinion, analysis, deals and more from the world of tech. 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. How big a black hole is needed for this story? Can a black hole be turned into a white hole? Poof, gone. Why hasn't the Attorney General investigated Justice Thomas? Proton exchange membrane (PEM) fuel cells: These are a type of fuel cell that use hydrogen and oxygen to produce electricity, with water as a byproduct. 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. on Facebook, Share Could aliens suck the energy from black holes with Dyson Spheres? WebBlack Hole Dyson Sphere TIMELAPSE | Dyson Sphere Program Nilaus 169K subscribers 321K views 1 year ago #DysonSphere #Factorio #LetsPlay TIMELAPSE No voice. 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. Dextre: Dextre is a robotic arm used on the International Space Station (ISS) for maintenance and repair tasks. With tweaks that ensure even greater accuracy, we will soon be using chatGPT and its descendants to design complex technological projects and explore creative ideas. I don't think so Dirk. While the jets speeding out from the poles of a stellar-mass black hole are nothing like those of supermassive black holes, the principle is the same, and the energy they represent is substantial. This would be a vast shell of energy collectors placed around a star to harvest its entire light output. One example of a PEM fuel cell that could be used for this application is the Ballard FCgen-H2PM fuel cell. Hertzsprung-Russell diagram: the most important graph in astrophysics, Exoplanets with moons may be likelier to host life, A fable of ancient Greece: when the mythic universe became a rational machine, Tolkien on the importance of fantasy and science fiction, Longer naps in the day may be an early sign of dementia in olderadults. 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. 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. 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. Time would move slower. You can find him online on Twitter at @thisdotjohn, Currently playing: Deep Rock Galactic, Destiny 2, Microsoft is holding a surprise event and it might be about Bing and ChatGPT, Watch and freak out a little as Boston Dynamics puts Atlas robot to work, Quordle today - hints and answers for Tuesday, April 18 (game #449). Can you extract much energy by encapsulating the hole entirely? 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. Hsiao and his collaborators from the Institute of Astronomy in Taiwan, brings us to the very edge of possibility itself. That's 20 times the data that Amazon Web Services holds, and it's effectively the storage backbone of the entire internet at the moment. Doing that is really hard work because it isn't gravitationally stable. At the heart of his theory is a simplebut tantalizingquestion: if a civilization grew large enough, and traveled far enough afield into outer space, how would it have enough energy to power itself? 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. After all, dont black holes swallow everything that falls into the event horizon, including light? Of all the considered parameters, the researchers conclude, just the accretion disk, the corona (which is the plasma gas surrounding a black hole), and the relativistic jets are promising energy sources. 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. It has a differentiated interior, which means that it has distinct layers of different materials, making it an interesting target for scientific exploration and mining. Dyson proposed the spheres as a solution to a growing alien civilization needing a large enough energy output to sustain its existence. The first describes vast, solar system-sized machines surrounding a star and built by a hyper-advanced civilization to harvest energy. 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. 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? That'd be a very interesting feature to be included. This energy-capturing sphere would radiate its enormous waste heat out in the infrared spectrum. Click to load last save.". 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. KelvinPlanck statement and entropy derivation. How challenging? Sandviks DE880 is a core drilling rig used for mineral exploration and geotechnical investigation. The estimated cost for a new LM90 is around $500,000. All that said, even though we imagine black holes as energy sinks rather than generators, that is not entirely the case. How small stars help with planet formation, Mike Sipser and Wikipedia seem to disagree on Chomsky's normal form. This makes me wonder: If the black holes in other galaxies were covered in dyson spheres Could we detect that currently? 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. Or at least, harder to tell that it was a Dyson Sphere.. 2023 BDG Media, Inc. All rights reserved. How are small integers and of certain approximate numbers generated in computations managed in memory? 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. That's not how black holes work, and probably shouldn't work that way in the game. Additionally, the cost would depend on the specific design and capabilities of the equipment required for the mission. Storage and transportation equipment: The refined metal would then need to be stored and transported to a construction site or to Earth. Okay, so we have our two super freaky ideas. According to Tolkien, fantasy requires a deep imagination known as sub-creation. And the genre reflects a fundamental truth of being human. 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. which is a just about $10^7$light-seconds, or 0.3 light-years. , but it 's still a pretty dramatic conversion of matter into energy a.
