Webb Space Telescope Image Shows Bright Galactic Collision, 2.29 billion years ago, This Cataclysmic Event Transformed the Makeup of Earths Crust. 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. I can think of another reason: use it as a. We're talking about a civilization that would be able to harness the power of earthquakes, volcanos, hurricanes, and even the energy output of the Earth's core all at once. Now, I realize that last sentence is pretty wild. That part requires thinking beyond just the Dyson sphere and expanding to a Dyson swarm or bubble. I flew into one, well as best as I could, it didn't do anything. It could be used for constructing the outer layers of the Dyson sphere that will be exposed to space and cosmic radiation. One example of a multi-junction solar cell that could be used for this application is the Boeing Spectrolab XTJ Prime. [11][12][13], On 14 October 2015, Planet Hunters' citizen scientists discovered unusual light fluctuations of the star KIC 8462852 raising press speculation that a Dyson sphere may have been discovered.

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. [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. This, it turns out, is pretty easy to answer as we speed into the 2020s and beyond. You might need an entire planets worth of material, Wright says. Power generation equipment: To power the mining and refining equipment, a source of energy would be needed. By subscribing to this BDG newsletter, you agree to our. It's part of Dyson's broader suggestion that the Search for Extra Terrestrial Intelligence (SETI) should set their sights on the kind of energy signature that such an item could discharge. 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. One example of a PEM fuel cell that could be used for this application is the Ballard FCgen-H2PM fuel cell. 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. The estimated cost of Dextre is $200 million. The estimated cost of a star tracker ranges from $100,000 to $500,000, depending on the capabilities. She's also an enthusiast of just about everything. Q: Ok, now lets see a few examples of human support equipment equipment and their approximate costs. A: There are currently no mining robots specifically designed for mining metals on Psyche, as no such mission has yet been undertaken. However, this step-by-step procedure provides a general outline of the tasks that would be involved if such a project were to be attempted. It could be used for the framework and support structure of the Dyson sphere. Not three million, just three kilometres. WebBlack Hole Dyson Sphere TIMELAPSE | Dyson Sphere Program Nilaus 169K subscribers 321K views 1 year ago #DysonSphere #Factorio #LetsPlay TIMELAPSE No voice. The first modern imagining of such a structure was by Olaf Stapledon in his science fiction novel Star Maker (1937). Include specific examples of spacesuits, life support equipment and medical equipment. What Happens When Two Black Holes Collide? The estimated cost for a new LM90 is around $500,000. The estimated cost for a new :D, I wish I'll have some energy fraction gettable from previous spheres as well as a reward. 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 to be visible radiation - it can be anything output by the enclosed object.. 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. Blackholes don't work like this. In the most literal way, we'd have to harvest energy from not only the sun, but from Jupiter (which is almost a star, itself) and everything else available to us in our solar system. Q: I think you have made a mistake. That'd be a very interesting feature to be included. Give specific examples. Q: Ok, now lets see a few examples of relevant storage and transportation equipment and their approximate costs. 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. Why? Take a look at Einstein saying light curves because the speed of light is spatially variable. 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. 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. A: Assuming a constant annual GDP growth rate of 2.5%, we can use the formula: where FV is the future value (i.e., $6.117 x 10^33), PV is the present value (i.e., the current world GDP, which is approximately $85 trillion), r is the annual growth rate (i.e., 2.5% expressed as a decimal, or 0.025), and n is the number of years. By creating a space-based structure, an alien civilization could meet the energy needs to push its civilization to the next level.

Q: Provide an estimate of the total amount of material we could get from completely mining all the asteroids in the solar system and also Io, Callisto, Ganymede, Europa and Mercury. 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. Now lets put them together in the same way Hsiao et al did. TechRadar is part of Future US Inc, an international media group and leading digital publisher. Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. New York, A growing alien civilization may need to develop a way to harvest the energy of their host star. Therefore, 4 x 10^20 kilograms of material would not be sufficient to construct a Dyson sphere of the size and composition you specified. Your pencil falls faster and faster and faster, and is allegedly going close to the speed of light at the event horizon, which would represent a huge mass deficit. NOTE: This answer has limited itself to considering a possible minimum safe distance for a dyson swarm and not a dyson shell. And that's your homework! MathJax reference. Gear-obsessed editors choose every product we review. Q: Ok, now lets see a few examples of relevant drilling equipment and their approximate costs. What is the difference between these 2 index setups? How can I detect when a signal becomes noisy? 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. 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. It radiates a lot of energy. What is amazing about this back and forth is that if I had to assemble the same set of answers together by doing a regular Google search or by constructing written sources, it would have taken me days, if not weeks, to do it. A Dyson sphere is a hypothetical megastructure that encompasses a star and captures a large percentage of its solar power output. 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. How challenging? Determine composition: Once a suitable asteroid has been identified, its composition needs to be determined. 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? The estimated cost of a fuel cell system ranges from $500 to $1,000 per kilowatt, depending on the size and configuration. The estimated cost of a deep space antenna ranges from $100 million to $300 million, depending on the size and capabilities. I suggest asking about orbits near a BH on. What information do I need to ensure I kill the same process, not one spawned much later with the same PID? Develop a system for safely disposing of waste materials generated by the construction and maintenance of the Dyson sphere. Q: Give me a list of equipment needed to mine all the metal on Psyche. Towing them around does require a rather large-scale propulsion system, though. I overpaid the IRS. Could you build a stable structure just short of the Schwarzschild radius or would you need to move farther back to be safe? 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. 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. But, the galaxy is an immense place with an estimated 400 billion stars in it. Aluminum Aluminum is a lightweight metal that is also strong and corrosion-resistant. A Dyson shell is (unfortunately) impossible to build. rev2023.4.17.43393. The main use of building a Dyson swarm around a black hole would be to capture the energy released by its accretion disk. Q: How much silicon, carbon and metals would be needed? Jupiter, for example, has a mass of approximately 1.898 x 10^27 kilograms, while Mercury has a mass of approximately 3.285 x 10^23 kilograms. Q: Ok, now lets see a few examples of relevant communication and navigation equipment and their approximate costs. 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. This would require specialized storage containers and transportation equipment, such as spacecraft or cargo ships. Life support equipment: A life support system is essential for providing astronauts with breathable air, removing carbon dioxide and other contaminants, and regulating temperature and humidity. Additionally, the cost would depend on the specific design and capabilities of the power generation equipment required for the mission. 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. Using current telescopes such as the Galaxy Evolution Explorer, an orbiting space telescope launched in 2003, the authors argue that one could detect such structure around a distant star. Some examples of communication equipment that could be used for the mission include deep space antennas, transponders, and modems. A: Including Jupiter and Mercury in our material sources would certainly increase the amount of material available for constructing a Dyson sphere. Can a black hole be turned into a white hole? How small stars help with planet formation, Mike Sipser and Wikipedia seem to disagree on Chomsky's normal form. Dyson shell is (unfortunately) impossible to build. 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.
