Aluminum Aluminum is also abundant in the solar system and can be found in a variety of sources, including the crusts of the rocky planets, asteroids, and comets. Also see Shapiro, and this Baez article: Einstein talked about the speed of light changing in his new theory. 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. Two Missions Will Investigate, Dazzling! Learn more about Stack Overflow the company, and our products. I was aiming at a ball park estimate instead of an exact figure. 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. A solar-sized black hole (BH) has a diameter of about 6000 m. It's apparent area is then $$A' = 4\pi r^2 = 4 \pi ({3000}^2) = 1.1 \times 10^8 m^2$$. Asking for help, clarification, or responding to other answers. Orbits near a black hole are strange and dont follow Keplers laws, and things are more interesting with rotating BHs. Honeybee Robotics Planetary Deep Drill: This is a lightweight, compact drill designed for deep drilling on other planets and asteroids. Boart Longyears LM90 is a compact underground diamond drilling rig used in mining and geotechnical applications. A: Mining all the metal on Psyche would be a massive undertaking, requiring a significant amount of equipment and resources. See this 2001 paper by Friedwardt Winterberg. 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. Spacesuits: A high-quality spacesuit can cost anywhere from $2 million to $12 million. Keeping space fairly clear of debris in the area. Several organizations, such as NASA and private companies like Planetary Resources and Deep Space Industries, have already identified potential asteroids for mining. Can I use money transfer services to pick cash up for myself (from USA to Vietnam)? @DirkBruere - In a .6 ly diameter Dyson sphere, a 6 km dia black hole radiation absorber is simply not going to make a difference. Based on the calculations I provided earlier, constructing a Dyson sphere with a radius of 1 AU and a thickness of 1 meter would require approximately 9.1 x 10^25 kilograms of material, assuming the material is evenly distributed across the sphere and has a density of 2 grams per cubic centimeter. [14][15] However, subsequent analysis showed that the results were consistent with the presence of dust. 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. Should the alternative hypothesis always be the research hypothesis? We are hundreds of years out from such a feat if something like this is even possible. I can think of another reason: use it as a. But, the galaxy is an immense place with an estimated 400 billion stars in it. 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. 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? 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.

I know it's a thought experiment now, but these are practical problems that must face any possible society capable of building these structures. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. {notificationOpen=false}, 2000);" x-data="{notificationOpen: false, notificationTimeout: undefined, notificationText: ''}">. This would be a vast shell of energy collectors placed around a star to harvest its entire light output. A curvature of rays of light can only take place when the velocity [speed] of propagation of light varies with position". Think about the energy required to carry more and more people into space as the world's billionaires venture outside of our planet, plus the energy demands for NASA's own ambitions to install people on the moon. 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. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. 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 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. Copper Copper is a good conductor of electricity and could be used for wiring and electrical components of the Dyson sphere. 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. Q: Give me a list of equipment needed to mine all the metal on Psyche. Converting all those hard X-rays to some form that's easier to transmit or store. However, here is a rough estimate of the costs of some of the equipment we have discussed: Overall, its possible that the total cost of the equipment required for a mining mission to Psyche could be in the range of several billion dollars. 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. Falling bodies do not slow down. 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. Next come black holes, which are far more well known. The major sources of each of these metals in the solar system vary depending on the specific metal. It uses a bucket-wheel excavation method to excavate regolith and other materials. It has a drilling depth of up to 1,000 meters and a hole diameter of up to 5 inches. .css-v1xtj3{display:block;font-family:FreightSansW01,Helvetica,Arial,Sans-serif;font-weight:100;margin-bottom:0;margin-top:0;-webkit-text-decoration:none;text-decoration:none;}@media (any-hover: hover){.css-v1xtj3:hover{color:link-hover;}}@media(max-width: 48rem){.css-v1xtj3{font-size:1.1387rem;line-height:1.2;margin-bottom:1rem;margin-top:0.625rem;}}@media(min-width: 40.625rem){.css-v1xtj3{line-height:1.2;}}@media(min-width: 48rem){.css-v1xtj3{font-size:1.18581rem;line-height:1.2;margin-bottom:0.5rem;margin-top:0rem;}}@media(min-width: 64rem){.css-v1xtj3{font-size:1.23488rem;line-height:1.2;margin-top:0.9375rem;}}All You Need to Know About Supernovae, Everything You Need to Know About Wolf-Rayet Stars, Meet the First Woman Astronaut on a Moon Mission. 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. Q: Ok. Lets go down the list of equipment one by one. Caroline Delbert is a writer, avid reader, and contributing editor at Pop Mech. There will be a component of velocity due to the black hole's gravitation. All black hole measurements may look roughly alike, but there will be "abnormal peaks" on those that are likely housing Dyson sphere technologies, the scientists say. (We need a theory of quantum gravity to really understand what happens at the singularity.) Thin-film solar cells: These are a type of solar cell that use a thin layer of semiconductor material deposited on a substrate, resulting in lower material costs and greater flexibility. When you purchase through links on our site, we may earn an affiliate commission. Additionally, a mission to Psyche would likely require additional equipment for radiation shielding and protection from other hazards of deep space travel. It uses a rotary-percussive drilling method and can drill up to 50 meters deep. 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. The first modern imagining of such a structure was by Olaf Stapledon in his science fiction novel Star Maker (1937). A Dyson shell is (unfortunately) impossible to build. 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. Recheck that answer. The Starship is currently in development and is designed to be a fully reusable spacecraft capable of carrying up to 100 metric tons of payload to the Moon, Mars, and other destinations in the solar system. Will this type of structure be added in the future? It could also be used for mining operations on an asteroid, such as moving and manipulating mining equipment. What metals could best be mined from asteroids for our purpose? Iron Iron is one of the most abundant elements in the solar system and can be found in many different sources, including the rocky planets (such as Earth, Mars, and Mercury), asteroids, and the sun. Would that give us enough material? Gold: Gold is a highly conductive and corrosion-resistant metal that could be used in the construction of the Dyson spheres electrical components. By creating a space-based structure, an alien civilization could meet the energy needs to push its civilization to the next level. The issue seems almost well consigned to science fiction, but it is an important one when talking about the search for extraterrestrial intelligence (SETI). rev2023.4.17.43393. 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. But Wright suggests it might be exceedingly difficult. 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 What could be better than a super freaky idea from the edges of astrophysics? Put someone on the same pedestal as another, What are possible reasons a sound may be continually clicking (low amplitude, no sudden changes in amplitude), Dystopian Science Fiction story about virtual reality (called being hooked-up) from the 1960's-70's. Q: Ok. Lets reduce the size of the Dyson sphere. It is estimated to be worth over $10,000 quadrillion, making it one of the most valuable objects in the solar system. How challenging? It is believed to contain water, carbon, and other minerals that could be valuable for space exploration and construction. 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.

Dyson Spheres Around Black Holes: the Ultimate Energy Source? I hope it is clear that the BH heat sinking has little effect on the energy balance of the DS. Bonus: we can use the energy signature of a Dyson sphere to search for. Terexs MT 5500AC is a haul truck used for transporting bulk materials in mining operations. Take a look at Einstein saying light curves because the speed of light is spatially variable. How can I detect when a signal becomes noisy? Further out, it will be much simpler and easier, but require more materials. " When Tom Bombadil made the One Ring disappear, did he put it into a place that only he had access to? If a strong enough material is used, an alien civilization could potentially tame a black hole, feeding it matter to produce energy and harness its force. 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. At the very least, my exchange with chatGPT shows that it can accelerate the process of gathering together information in a coherent manner exponentially, and a not insignificant reason for this is its ability to understand natural human language and then put together answers based on that understanding. Solving for the radius of the sphere R gives $$R = 3\times 10^{15} meters$$ This is then dependent of the capacity of this world's technology, For example, if the maximum velocity attainable is half the speed of light, then the dyson swarm will be orbiting the black hole with an orbital velocity of approximately 0.5 c. Now you need to factor in the mass of the black hole and will yield what may be the minimum safe distance (assuming there are no other factors to endanger the dyson swarm). The dyson sphere would have to be constructed in such a way that its mass was uniform in all directions done the planck length. Some of the metals that could be mined from asteroids for this purpose include: Overall, asteroid mining could provide a valuable source of metals for the construction of a Dyson sphere, and ongoing research and development in this field could help to make this a more feasible and cost-effective option in the future. (I was especially impressed by the level of detail, including equipment type and cost, that chatGPT included in its answers). We would need significantly more material, potentially from other sources such as mining other planets or moons in the solar system, or developing new methods for obtaining and processing materials. The original site was designed by S. Abbas Raza in 2004 but soon completely redesigned by Mikko Hyppnen and deployed by Henrik Rydberg. If Fine Structure Constant in not uniform in space what would that imply for cosmic background? When NikolaiKardashev later devised a scale for classifying advanced aliens based on their capacities to harvest energy, he used the Dyson Sphere as a signature of a Type II civilization. In principle, no, you cannot make a Dyson sphere which is indistinguishable from the CMB. The reason is fairly simple.
