The estimated cost of the RESOLVE drill is $10 million. The estimated cost for a new HIGmill ranges from $500,000 to $5 million, depending on the size and configuration. Converting all those hard X-rays to some form that's easier to transmit or store. 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. But let's run the numbers anyways. Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. The dyson sphere would have to be constructed in such a way that its mass was uniform in all directions done the planck length. Doing that is really hard work because it isn't gravitationally stable. In the case of a solid body, the swallowing of mass has a cumulative effect. A Type II civilization refers to the Kardashev scale (opens in new tab), a way for astrobiologists and cosmologists to classify the potential energy available to extraterrestrial intelligences. It would produce far more energy than even a normal Dyson Sphere. A: For fuel cells, some examples that could be used for powering mining and refining operations on Psyche include: For solar panels, some examples that could be used for powering mining and refining operations on Psyche include: Its worth noting that the specific types of fuel cells and solar panels that would be used for the mission would depend on a variety of factors, including the mission requirements, the specific characteristics of the asteroid, and the available technology at the time of the mission. Does Chain Lightning deal damage to its original target first? 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? Let's say an individual's memories and mind fit into 2.5 terabytes of storage, which is an extremely low estimatethat means there's a server farm somewhere with 20 billion terabytes, which is 20 million petabytes, or about 20 exabytes. Also note that gravity is not a force in the Newtonian sense. TLDR 1: All useful energy comes from moving things from a low-entropy to high-entropy state, and doing something useful in the middle. This makes me wonder: If the black holes in other galaxies were covered in dyson spheres Could we detect that currently? This perception is based on a literal interpretation of Dyson's original 1960 paper. Asking for help, clarification, or responding to other answers. The estimated cost of a robotic arm ranges from $1 million to $5 million, depending on the capabilities. 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. The black hole is surrounded by its event horizon, a boundary that outlines the black hole from which nothing that enters the black hole can be observed from outside. In the English translation of his 1920 book "Relativity: the special and general theory" he wrote: "according to the general theory of relativity, the law of the constancy of the velocity [Einstein clearly means speed here, since velocity (a vector) is not in keeping with the rest of his sentence] of light in vacuo, which constitutes one of the two fundamental assumptions in the special theory of relativity [] cannot claim any unlimited validity. 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. There may not even be any other civilizations out there, advanced or otherwise. 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. Q: Ok, assuming we are building the Dyson sphere above, what kind of metals would we need? 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. The estimated cost for a new Metal Bin ranges from $5,000 to $20,000, depending on the size and configuration. 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. They have been featured in science fiction books and TV shows including Star Trek. This could be done using spacecraft or by launching the metals from the asteroids surface using a catapult-like device. The estimated cost for a new LM90 is around $500,000. 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. Valve Corporation. This obviously involves some pretty extreme astronomical engineering. The Human Research Facility (HRF) on the International Space Station includes equipment for studying cardiovascular function, muscle and bone loss, and other medical issues. Solar panels: Solar panels are a common source of power for remote operations. Since, the game has black holes, so it would be interesting and awesome (in my opinion), if you could be able to build black hole energy gathering structures. The first question you are probably asking is, how can you get any energy out of a black hole? Nothing with structural strength high enough exists, and it would require continual adjustment to not fall into the star/black hole. 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. Can we create two different filesystems on a single partition. Develop a system for safely disposing of waste materials generated by the construction and maintenance 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. If you want to have so many of them that you block a significant amount of the sun's light, then we would need to build billions and billions more of them. Medical equipment: Medical equipment for space missions needs to be lightweight, compact, and able to operate in microgravity. rev2023.4.17.43393. I know it's a thought experiment now, but these are practical problems that must face any possible society capable of building these structures. Honeybee Robotics Planetary Deep Drill: This is a lightweight, compact drill designed for deep drilling on other planets and asteroids. 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. It only takes a minute to sign up. Develop technology capable of producing and manipulating matter at an incredibly large scale, allowing for the construction of a structure large enough to enclose the entire solar system. Hsiao and his collaborators from the Institute of Astronomy in Taiwan, brings us to the very edge of possibility itself. Nothing with structural strength high enough exists, and it would require continual adjustment to not fall into the star/black hole. It is the largest object in the asteroid belt, and it is thought to contain significant amounts of water, carbon, and other valuable minerals. @Len - other way around. 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. I suggest asking about orbits near a BH on. And what Winterberg is saying is that something's got to give, like the wave nature of matter.

However, its important to note that these estimates are highly uncertain and based on limited data, and the actual amounts of material available could be significantly different. Why hasn't the Attorney General investigated Justice Thomas? Its design could potentially be adapted for use on Psyche to mine the asteroids metal surface. 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. Recheck that answer. 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. Valve Corporation. Determine composition: Once a suitable asteroid has been identified, its composition needs to be determined. Nickel Nickel is abundant in the metallic cores of the rocky planets and can also be found in asteroids and comets. We can start with the Dyson Sphere. 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 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. WebBlack Hole Dyson Sphere TIMELAPSE | Dyson Sphere Program Nilaus 169K subscribers 321K views 1 year ago #DysonSphere #Factorio #LetsPlay TIMELAPSE No voice. In response to letters prompted by some papers, Dyson replied, "A solid shell or ring surrounding a star is mechanically impossible. If we were to mine asteroids, what kind of construction, human support, transportation and communication equipment would we need? How, then, could this civilization harvest the energy? Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. @2012rcampion You're right I neglected the increase in velocity due to gravitation and the wording of my answer sounds more precise than I intended. Q: Ok, now lets see a few examples of relevant metal refining equipment and their approximate costs. What is the etymology of the term space-time? 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 the Some scientists believed that the star, officially known as KIC 8462852 but later dubbed Boyajians Star, had a Dyson sphere built around it, which resulted in its strange dimming. However, we can use current market prices as a rough estimate. 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. By subscribing to this BDG newsletter, you agree to our. Stand on a chair and drop a pencil. A Dyson sphere is a theoretical megastructure that surrounds a star to collect its energy output. A: Asteroid mining is a potential source of various metals that could be used for building a Dyson sphere around the solar system. Bonus: we can use the energy signature of a Dyson sphere to search for. The natural follow-up question is why we'd need that much energy in the first place. This can be done through remote sensing techniques, such as spectroscopy, which can provide information on the asteroids mineral composition. Estimates suggest that Europas surface may contain around 10^17 kilograms of water ice, as well as significant amounts of other volatiles such as carbon dioxide and sulfur dioxide. Finding valid license for project utilizing AGPL 3.0 libraries. 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? 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. :D, I wish I'll have some energy fraction gettable from previous spheres as well as a reward. Or at least, harder to tell that it was a Dyson Sphere.. Now, all of this is obviously the purest of pure speculation. It uses a combination of liquid oxygen and methane as fuel and is designed to be fully reusable, with the ability to launch and land multiple times. Q: Ok. Give me a detailed plan for mining asteroids for some of these metals. The form of 'biosphere' which I envisaged con We may earn commission if you buy from a link. NOTE: This answer has limited itself to considering a possible minimum safe distance for a dyson swarm and not a dyson shell. The mission would involve sending a spacecraft to the asteroid to extract the desired metals. If their maximum attainable velocity is one-half lightspeed, the dyson swarm units will be able to boost away from orbit around the back hole, if they need to (just think of it as an additional safety feature). Dyson shell is (unfortunately) impossible to build. Combining those challenges with the properties of a black hole gets even more tricky. For starters, its hard to imagine what even a Type I civilization would look like. 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. 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. This is the point at which an Earth far into the future might need to harness the full power of the sun, and the point at which we'd become a Kardashev type 2 civilization. It has a drilling depth of up to 1,000 meters and a hole diameter of up to 5 inches. Because only a tiny fraction of a star's energy emissions reaches the surface of any orbiting planet, building structures encircling a star would enable a civilization to harvest far more energy. 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. Titanium Titanium is a lightweight and strong metal that is also corrosion-resistant. This method, they say, is more intensive than previous attempts to study black hole energy-harvesting, which have only explored the accretion disk (the structure of a black hole that you typically picture) or the cosmic microwave background (CMB), the electromagnetic radiation that remains from the earliest stages of the universe. 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. 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. According to Tolkien, fantasy requires a deep imagination known as sub-creation. And the genre reflects a fundamental truth of being human. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Navigation equipment: Navigation equipment is important for accurately navigating the spacecraft to the asteroid and for guiding the mining and refining operations on the asteroid. The energy doesn't have Launch these components into space and gradually attach them to the Dyson sphere until it fully encloses the solar system. [7], Dyson-style energy collectors around a distant star would absorb and re-radiate energy from the star. 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. Iron Iron is a common construction material due to its strength, durability, and abundance. Europa: Europa is another moon of Jupiter and is thought to have a subsurface ocean beneath its icy surface. I expect there would be neutrinos too, but it's still a pretty dramatic conversion of matter into energy. That's because the potential energy is mass-energy, in the pencil. Sign up to receive daily breaking news, reviews, opinion, analysis, deals and more from the world of tech. I think Dirk has a valid point, but +1 for rigor and effort and a fun read. Estimates suggest that Mercurys crust may contain around 10^20 kilograms of metal, including significant amounts of iron and aluminum. In 1960, physicist Freeman Dyson published a paper in the journal Science describing how a technologically advanced civilization would make its presence known. Thermodynamically possible to hide a Dyson sphere? How challenging? Withdrawing a paper after acceptance modulo revisions? Outotecs Kaldo furnace is a rotary furnace used for smelting and refining various metals, including nickel, copper, and zinc. The major sources of each of these metals in the solar system vary depending on the specific metal. [23], Fictional Dyson spheres are typically solid structures forming a continuous shell around the star in question, although Dyson himself considered that prospect to be mechanically implausible. Should a civilization this advanced exist, then they would probably already know of our existence by the time we discover the black hole Dyson sphere. [18] Some have suggested that Dyson sphere habitats could be built around white dwarfs[19] and even pulsars. Now, the NTHU researchers have figured that capturing the energy of a stellar mass black hole could provide as much as five times the amount of energy captured by a main sequence star, and might even be more visible as a result even using current telescopes. No clickbait, no fake news, not just entertainment, but depth and breadth something increasingly hard to find on the internet today. 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. Now if a star is inserted into the sphere, since the external radiation remains unchanged the surface of the DS must increase its temperature in order to radiate away the internally-generated heat. After all, dont black holes swallow everything that falls into the event horizon, including light? Theres little doubt to me that we are in a new regime of machine intelligence here, one that surpasses anything we have seen before. Webb Space Telescope Image Shows Bright Galactic Collision, 2.29 billion years ago, This Cataclysmic Event Transformed the Makeup of Earths Crust. Building a Dyson sphere is about capturing energy output and using that to power to run the civilisation inhabiting the sphere. Vesta: Vesta is a large asteroid located in the asteroid belt that is thought to contain significant amounts of iron, nickel, and other minerals. Black Holes store rotational energy that can be harnessed through magnetic reconnection and dropping material in to the ergosphere. Solar panels could be used to generate electricity on the asteroids surface, or a nuclear reactor could be used for continuous power generation. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Indeed, the paper, by T.Y. 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. One example is the Extravehicular Mobility Unit (EMU) used by NASA for spacewalks. Fictional depictions often describe a solid shell of matter enclosing a star an arrangement considered by Dyson himself to be implausible. Share Could aliens suck the energy from black holes with Dyson Spheres? Put someone on the same pedestal as another. Search for Extra Terrestrial Intelligence (SETI), the world's billionaires venture outside of our planet, Your Privacy Choices: Opt Out of Sale/Targeted Ads, Extraterrestrials could use Dyson spheres to harvest. What Lies Beneath the Ice of Jupiter's Moons? I asked AI engine chatGPT to build me a hypothetical 2 meter thick Dyson sphere at a distance of 2 AU (~300 million kilometers). For a Dyson sphere thats at 2 AU and 2 meters thick, how many asteroids would we need to completely mine? 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). $\begingroup$ Building a Dyson sphere is about capturing energy output and using that to power to run the civilisation inhabiting the sphere. 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. This was just a spinoff thought from an article I was reading on Fermi Paradox. 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.
