The area around the black hole is extremely energetic, with its accretion disk accelerating matter so fast that it radiated energy for brighter than a star. The estimated cost for a new Kaldo furnace is around $10 million. One example of a PEM fuel cell that could be used for this application is the Ballard FCgen-H2PM fuel cell. Silicon: (0.5) * (4.18 x 10^23 g) = 2.09 x 10^23 g, Carbon: (0.25) * (4.18 x 10^23 g) = 1.04 x 10^23 g, Metals: (0.25) * (4.18 x 10^23 g) = 1.04 x 10^23 g, Carbon: $1.00 $10.00 per kg (depending on the type of carbon), Silicon: (2.09 x 10^23 g) * ($1.00 $2.50 per kg) $4.18 x 10^23 $1.04 x 10^24, Carbon: (1.04 x 10^23 g) * ($1.00 $10.00 per kg) $1.04 x 10^23 $1.04 x 10^24, Metals: (1.04 x 10^23 g) * ($0.50 $1.50 per kg) $5.21 x 10^22 $1.56 x 10^23, Silicon: (0.5) * (1.67 x 10^24 g) = 8.35 x 10^23 g, Carbon: (0.25) * (1.67 x 10^24 g) = 4.18 x 10^23 g, Metals: (0.25) * (1.67 x 10^24 g) = 4.18 x 10^23 g, Silicon: (8.35 x 10^23 g) * ($1.00 $2.50 per kg) $1.67 x 10^24 $4.18 x 10^24, Carbon: (4.18 x 10^23 g) * ($1.00 $10.00 per kg) $4.18 x 10^23 $4.18 x 10^24, Metals: (4.18 x 10^23 g) * ($0.50 $1.50 per kg) $2.09 x 10^23 $6.26 x 10^23. Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. Its design could potentially be adapted for use on Psyche to mine and collect metal samples. Dyson Spheres Around Black Holes: the Ultimate Energy Source? The concept was later explored by the physicist Freeman Dyson in his 1960 paper "Search for Artificial Stellar Sources of Infrared Radiation". This is significantly more than the estimated 4 x 10^20 kilograms of material that could be obtained from mining all of the asteroids in the solar system and the selected moons. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. The next major revision was designed by S. Abbas Raza, building upon the earlier look, and coded byDumky de Wildein 2013. Identify asteroids: The first step in asteroid mining is to identify suitable asteroids. 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. This difference in speeds is precisely that referred to above by ceiling and floor observers. Q: Ok. Give me a detailed plan for mining asteroids for some of these metals. You'll also have to arrange for occasional gaps in the swarm to allow more matter to be fed to the accretion disc, but that is much easier than the other challenges of this project. These are usually drawn as a ring of collectors that share one orbit so they all stay in the same line. Is there a way to use any communication without a CPU? However, a Dyson swarm could be built relatively close to the event horizon, albeit at the massive cost of accelerating the individual satellites to near-lightspeed to achieve orbit. Their goal is to explore the power needs of a civilization making the jump from a type 2 to a type 3 civilization, which could be Earth in as little as 1,000 years, according to their scientific napkin math. Thermodynamically possible to hide a Dyson sphere? This is completely free of charge for everyone. 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. Because who have not tried to enter the Black Hole? Stand on a chair and drop a pencil. 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. Converting all those hard X-rays to some form that's easier to transmit or store. A Dyson swarm is a collection of individual, smaller "harvesters" of some kindthat could be solar panels used extremely close up, for examplethat are loosely circulated. Why should there be an accretion disc? Q: How much silicon, carbon and metals would be needed? How to intersect two lines that are not touching. [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. One example is the Extravehicular Mobility Unit (EMU) used by NASA for spacewalks. 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. But what if a more advanced extraterrestrial civilization is not only building megastructures that surround stars, but turning to the infamous beasts of the cosmos for energy: black holes. Give me some details on the kind of rocket or launch vehicle that would work. While this is the A: Reducing the thickness of the Dyson sphere from 2 meters to 1 meter and placing it at 1 AU from the sun would result in a significant decrease in the required amount of material. If we were to mine asteroids, what kind of construction, human support, transportation and communication equipment would we need? As of April 2023, the price per kilogram of silicon, carbon, and steel are approximately: Using these prices, the total cost of the materials required to build the Dyson sphere would be: Again, these estimates should be taken with a grain of salt, as the engineering and construction of a Dyson sphere is purely hypothetical and would involve many unknown factors. These days, astronomers talk instead about Dyson Swarms dense arrays of orbiting energy collectors. Can I ask for a refund or credit next year? It will be capable of carrying up to 130 metric tons of payload into low Earth orbit, making it one of the most powerful rockets ever built. "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. Q: What would be a good way to send all this equipment to Psyche? Black holes can form at the center of stars in the Milky Way. Thanks for contributing an answer to Physics Stack Exchange! Could you build a stable structure just short of the Schwarzschild radius or would you need to move farther back to be safe? Falling bodies do not slow down. Also note that gravity is not a force in the Newtonian sense. This, it turns out, is pretty easy to answer as we speed into the 2020s and beyond. Get counterintuitive, surprising, and impactful stories delivered to your inbox every Thursday. Even as this advanced alien civilization soaked up all that energy, they could not help but bleed off excess heat into space, lest their platforms melt entirely. Ceres: Ceres is a dwarf planet located in the asteroid belt between Mars and Jupiter. 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. 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. The estimated cost of the Honeybee Robotics Planetary Deep Drill is not publicly available. Gekko Systems InLine Leach Reactor is a modular system used for leaching and recovering metals from ores and concentrates. WebA black hole with the same mass has a diameter of under three. Outotecs Kaldo furnace is a rotary furnace used for smelting and refining various metals, including nickel, copper, and zinc. 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. 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. Carnegie Mellons Scarab is a prototype robot designed to autonomously search for and collect mineral samples in extreme environments. The mission would involve sending a spacecraft to the asteroid to extract the desired metals. So one way to find out alien civilizations would be to look for signatures of this infrared radiation in space. I am reviewing a very bad paper - do I have to be nice? From this you can calculate that, at 2.75 K, the emitted power of a black body is about 3.2 $\mu$W /$m^2$. Communication equipment: Communication equipment is critical for maintaining contact with the mining and refining operations on Psyche, as well as for transmitting data and other information back to Earth. 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. 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. 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. Therefore, 4 x 10^20 kilograms of material would not be sufficient to construct a Dyson sphere of the size and composition you specified. A: Here are a few examples of drilling equipment that could potentially be used for mining on Psyche, along with their estimated costs: Its worth noting that the cost of drilling 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. In fictional accounts, the Dyson-sphere concept is often interpreted as an artificial, hollow sphere of matter around a star. Alternately, you can think about an entire world powered by electric batteries instead of fossil fuels. 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. A black hole Dyson Sphere would be the mark of a Type III civilization one with the capacity to collect the energy equivalent of an entire galaxy. He speculated that this could be done via a system of structures orbiting the star, designed to intercept and collect its energy. Not so (in any meaningful way) for the energy which is constantly being generated by the civilization which operates the DS. Begin constructing the Dyson sphere by launching robotic spacecraft into space that can collect raw materials from nearby asteroids and comets. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. One example of an SOFC that could be used for this application is the Bloom Energy Server. It has a drilling depth of up to 45 feet and a hole diameter of up to 12.25 inches. These robots would need to be able to operate in the low-gravity environment of the asteroid and withstand the extreme temperatures and radiation levels. As the pencil falls, potential energy is being converted into kinetic energy. I think it's essentially correct. 16 Psyche has an estimated mass of approximately 1.7 x 10^19 kg. 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. 2023 BDG Media, Inc.

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. 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. 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. Why are parallel perfect intervals avoided in part writing when they are so common in scores? Freeman Dyson proposed the idea in the early 1960s. This is just one of the many 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. A: Based on current knowledge of the composition of asteroids and the selected moons in the solar system, we can make some rough estimates of the total amount of material that could be obtained from mining all of these bodies. .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. Q: Ok, now add up all these costs and give me an approximate number. 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. However, a Dyson swarm could be built relatively close to the event horizon, albeit at the massive cost of accelerating the individual satellites to near-light-speed to achieve orbit. We may earn commission if you buy from a link. Further out, it will be much simpler and easier, but require more materials" Anything that crosses the event horizon is lost forever from our Universe. Some examples of navigation equipment that could be used for the mission include star trackers, gyroscopes, and accelerometers. The secret to this technique is to choose the right placelike the black hole's coronato collect energy. If nothing else, it would be able to provide excellent starting points. If you built the sphere, at the optimum radial distance, then insulated the exterior as much as possible, would the gravitational redshift provide It could be used for constructing the outer layers of the Dyson sphere that will be exposed to space and cosmic radiation. Something's wrong. This means that a Penrose sphere is far smaller than a Dyson sphere encasing a star of equivalent mass. 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. They can accomplish this by using space-based stellar energy harvesting swarms. 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. Q: I think you have made a mistake. These structures became known as Dyson spheres, and a handful of programs have sought them out by looking for weird infrared signatures around neighboring stars. Put someone on the same pedestal as another. When you purchase through links on our site, we may earn an affiliate commission. Therefore, its unlikely that we would have enough material to construct a Dyson sphere of the size and composition you specified using only the asteroids and selected moons mentioned earlier. What could be better than a super freaky idea from the edges of astrophysics? Additionally, a mission to Psyche would likely require additional equipment for radiation shielding and protection from other hazards of deep space travel. Or at least, harder to tell that it was a Dyson Sphere.. Penn State Extraterrestrial Intelligence Center. And that's your homework! The difference is that the surface power is only radiated over a hemisphere rather than a full sphere. This distance would need to be far enough away to avoid the intense heat and radiation of the sun, but close enough to capture a significant amount of its energy.
