The sphere has been traveling towards the galactic core for several billion years at sub-light speed and intends to enter a black hole as part of an ancient compact. However, its important to note that this is a very rough estimate and should not be taken as an accurate cost calculation. @DirkBruere - In a .6 ly diameter Dyson sphere, a 6 km dia black hole radiation absorber is simply not going to make a difference. Silicon, carbon, and metals are likely to be among the most commonly used materials. One example of a PEM fuel cell that could be used for this application is the Ballard FCgen-H2PM fuel cell. While predominantly focused on the radio signals produced by an alien civilization, the problem becomes what happens if an alien civilization is not broadcasting them for reasons of self-preservation (i.e., you can't come and invade what you don't is there). Some of the questions I asked chatGPT included: I verified at least some (but not all) of the numbers it gave me from other sources and was finally able to arrive at the following conclusion: Building a 1 meter thick Dyson sphere at 1 AU from the sun would take approximately 10^25 kilograms of material. Espaol - Latinoamrica (Spanish - Latin America). A: Here are a few examples of communication and navigation equipment that could be used for the mission to Psyche, along with their estimated costs: Its worth noting that the cost of communication and navigation equipment for use on the mission to 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 deep space and an asteroid. 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. While the hot material stays beyond the singularitys event horizon, it can emit energy that radiates away into space. 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. Here is a list of some of the equipment that would likely be needed for such a project: Overall, mining all the metal on Psyche would require a significant investment of resources and technology, and it would likely be a long-term project that would require ongoing research and development. WebBlack Holes could actually theoretically be used to harvest energy in a lot of ways, the chief one being using its gravitational force to accelerate light beamed into its vicinity and then They suffer a form of annihilation, and the result is a gamma ray burst. However, we've yet to even find traces of bacteria on another world, much less something this, well, epic in scale. Launch these components into space and gradually attach them to the Dyson sphere until it fully encloses the solar system. And that's challenging.. A: Its difficult to provide precise numerical estimates for the amount of silicon, carbon, and metals that would be needed to build a 2 m thick Dyson sphere at a distance of 2 AU from the sun, as the design and engineering of such a structure is purely theoretical and dependent on a number of unknown factors. 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. Fictional depictions often describe a solid shell of matter enclosing a star an arrangement considered by Dyson himself to be implausible. 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. Solving for the radius of the sphere R gives $$R = 3\times 10^{15} meters$$ The questions I answered were simple, the answers complex. The researchers behind the new study suggest that building a Dyson sphere around a black hole would allow an alien civilization to garner energy from six sources: By not only relying on radiation as the main source of energy but a Dyson sphere around a black hole would also collect five times as much energy as one around a star, according to the study. 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. A growing alien civilization may need to develop a way to harvest the energy of their host star. In general, that'd be harder to detect, he says. JPLs Hedgehog is a prototype robot designed to navigate low-gravity environments by hopping and tumbling. Dyson Spheres Around Black Holes: the Ultimate Energy Source? Iron: Iron is one of the most abundant metals in the universe and could be used in the construction of the Dyson spheres structural components. All rights reserved. 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. Outotecs Kaldo furnace is a rotary furnace used for smelting and refining various metals, including nickel, copper, and zinc. I was thinking of a radius of 2 AU. The issue seems almost well consigned to science fiction, but it is an important one when talking about the search for extraterrestrial intelligence (SETI). In 1960, physicist Freeman Dyson published a paper in the journal Science describing how a technologically advanced civilization would make its presence known. One example of a thin-film solar cell that could be used for this application is the First Solar Series 6. : You cant pull energy out of a black hole, its physically imposible, just like you cant travel in time. The recent study suggests that instead of building a Dyson sphere around a star, a civilization can build the same megastructure around black holes. This short story is a fictional account of two very real people Anaximander and Anaximenes, two ancient Greeks who tried to make sense of the universe. Only at the event horizon, the coordinate speed of light is zero, and the pencil is supposedly falling 299,792,458 m/s faster than that. Some way of starting a new system with your upgrades. "In this paper, we consider and discuss six types of energy sources: the CMB, the Hawking radiation, an accretion disk, Bondi accretion, a corona, and the relativistic jets from two types of black holes: a non-rotating black hole and a rotating black hole," the researchers explain. This would require specialized refining equipment, such as smelters and chemical processing equipment. 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. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Its design could potentially be adapted for use on Psyche to mine the asteroids metal surface. I flew into one, well as best as I could, it didn't do anything. This is just one of the many 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 It has a drilling depth of up to 45 feet and a hole diameter of up to 12.25 inches. Assuming a Dyson sphere with a radius of 1 AU (the distance from the sun to Earth), a thickness of 2 m, and a density of 2.5 g/cm^3 (comparable to the density of rock), the total mass of the Dyson sphere would be approximately: Mass = (4/3) * pi * (1 AU)^3 * (2.5 g/cm^3) * (2 m) 4.18 x 10^23 g. To build such a structure, large quantities of various materials would be required. 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. If you built the sphere, at the optimum radial distance, then insulated the exterior as much as possible, would the gravitational redshift provide A relativistic Kessler cascade is going to be a horrible problem. About one one-billionth of the Suns total energy output actually reaches the Earth. Give me a few examples of mining robots for mining metals on Psyche and their approximate cost. New external SSD acting up, no eject option. 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. To absorb the accretion disc luminosity, a Dyson ring or a Dyson Swarm could be a Assuming a thickness of 2 m and a density of 2.5 g/cm^3, the total mass of the Dyson sphere would be approximately: Mass = (4/3) * pi * (2 AU)^3 * (2.5 g/cm^3) * (2 m) 1.67 x 10^24 g. Using the same mix of 50% silicon, 25% carbon, and 25% metals by weight, the mass of each material required would be: As for the costs, using the same prices as in my previous response, the total cost of the materials required to build the Dyson sphere would be: The total cost would depend on the specific prices of the materials used and their availability.

Drilling equipment: Depending on the location and distribution of the metal on Psyche, drilling equipment may be needed to access the metal deposits deep within the asteroid. If that is close enough to "insignificant", there is no need to go further. 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. 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). it would have been funnier if you get close, and the gravity is so strong you cannot fight it, get sucked in and it says, "Game Over. :D, I wish I'll have some energy fraction gettable from previous spheres as well as a reward. Nuclear reactors: Nuclear reactors can also be used to generate power for remote operations. Theres also a possibility that a meteor or asteroid could nudge one of the pieces out of place. 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? 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. 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. Since it is surrounded by CMB with an effective temperature of 2.75 K, it will reach an equilibrium temperature of 2.75 K. That's what thermal equilibrium means for a black body. Lets unpack things a bit. 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. Wormholes, yes, blackholes, no. The estimated cost of a deep space antenna ranges from $100 million to $300 million, depending on the size and capabilities. NASAs RASSOR (Regolith Advanced Surface Systems Operations Robot) is a lunar mining robot that was developed to excavate and transport lunar regolith. 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. Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. Alternately, you can think about an entire world powered by electric batteries instead of fossil fuels. Think of a Dyson Sphere is a very large building on a wall, Wright says. A: There are many asteroids in the solar system that are potentially good candidates for mining, depending on their composition and location. Next come black holes, which are far more well known. 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.
