Dyson Spheres Around Black Holes: the Ultimate Energy Source? (We need a theory of quantum gravity to really understand what happens at the singularity.) Valve Corporation. 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. The questions I answered were simple, the answers complex. can one turn left and right at a red light with dual lane turns?

When the pencil hits the floor this kinetic energy is dissipated, and you're left with a mass deficit. 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. Don't forget the sphere would experience time dilation, so that's a factor. Solar panels are more effective on planets close the sun while swarms are more effective if the sun has high luminosity. So if you think about (Boyajians) Star, and the way that it got dimmer and all of its weirdness [] That's the sort of thing they're looking for, more of those.. The estimated cost for a new DM30 II is around $1.5 million. Thanks for contributing an answer to Physics Stack Exchange! 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. How big a black hole is needed for this story? This can be done through remote sensing techniques, such as spectroscopy, which can provide information on the asteroids mineral composition. By subscribing to this BDG newsletter, you agree to our. 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. Q: Ok, now lets see a few examples of human support equipment equipment and their approximate costs. Estimates suggest that Callistos surface may contain around 5 x 10^17 kilograms of water ice, as well as significant amounts of other volatiles such as carbon dioxide and ammonia. Dyson spheres have not been detected yet, but an advanced alien civilization would surely need them. We also discuss a possible location of a Dyson sphere around a black hole. Therefore, it is likely that mining all known asteroids and the metal-rich moons of Jupiter and Saturn, as well as completely disassembling Jupiter and Mercury, would provide enough material to construct a Dyson sphere that is 1 m thick, 1 AU from the sun, and has a composition of 50% silicon, 30% carbon, and 20% metals. 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. Q: What would be a good way to send all this equipment to Psyche? Multi-junction solar cells: These are a type of solar cell that use multiple layers of semiconductor material to absorb a wider range of wavelengths of light, resulting in higher efficiency. Bonus: we can use the energy signature of a Dyson sphere to search for. 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. There are a few people who think about looking for them, they are looking for large structures that might pass in front of the star or anything else, but large things, Jason Wright, a Penn State astronomer and director of the Penn State Extraterrestrial Intelligence Center, tells Inverse. For starters, its hard to imagine what even a Type I civilization would look like. How can I detect when a signal becomes noisy? How to intersect two lines that are not touching. Ganymede: Ganymede is the largest moon of Jupiter and is known to have significant deposits of various metals, including iron, nickel, and aluminum. Theres also a possibility that a meteor or asteroid could nudge one of the pieces out of place. Number of asteroids required = Mass of Dyson sphere / Mass of average asteroid Number of asteroids required = 5.03 x 10^5 kg / 1.7 x 10^19 kg = 2.96 x 10^-14 asteroids. What would be its composition? This would include satellite communication systems, GPS, and other navigation tools. 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. Hsiao and his collaborators from the Institute of Astronomy in Taiwan, brings us to the very edge of possibility itself. Give me some details on the kind of rocket or launch vehicle that would work. This makes sense as a way to predict movement, create stability, and easily adjust or work on any individual unit in the Dyson swarm.

Dyson shell is (unfortunately) impossible to build. 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. Q: What if we include Jupiter and Mercury and completely disassemble them? It is estimated to be worth over $10,000 quadrillion, making it one of the most valuable objects in the solar system. 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. WebThe innermost Dyson sphere of the Matrioshka brain would draw energy directly from the star it surrounds and give off large amounts of waste heat while computing at a high temperature. We've only been able to detect the presence of a few thousand exoplanets around alien stars. Let's start with a blackbody DS which encloses nothing at all, and is so far from any nearby stars that no noticeable radiation reaches it. In the case of a solid body, the swallowing of mass has a cumulative effect. Here are a few examples: Its worth noting that the cost of developing and deploying mining robots for use on Psyche would likely be much higher than the cost of the above projects, due to the unique challenges and extreme environment of mining on an asteroid.

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. Power generation equipment: To power the mining and refining equipment, a source of energy would be needed. As for how your managed BH Dyson sphere might fare, have you ever seen a Chinese lantern catch fire? If that is close enough to "insignificant", there is no need to go further. I wanted to see how efficiently chatGPT harnesses information from the internet to give me specifics and how well its large language model (LLM) of computation understood what I was saying. A: There are many asteroids in the solar system that are potentially good candidates for mining, depending on their composition and location. Give me a few examples of mining robots for mining metals on Psyche and their approximate cost. Mining robots: Psyche is believed to be made almost entirely of metal, so specialized mining robots would be needed to extract the metal from the asteroids surface and interior. Okay, so we have our two super freaky ideas. It is the largest object in the asteroid belt, and it is thought to contain significant amounts of water, carbon, and other valuable minerals. Building a Dyson Shell around a black hole? That'd be a very interesting feature to be included. Inspired by the 1937 science fiction novel Star Maker by Olaf Stapledon,[4] the physicist and mathematician Freeman Dyson was the first to formalize the concept of what became known as the "Dyson sphere" in his 1960 Science paper "Search for Artificial Stellar Sources of Infra-Red Radiation". 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. 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. Based on estimates from the Galileo mission, its been suggested that Ios surface may contain around 10^18 kilograms of sulfur.

Can a Dyson Sphere around a Black Hole be built so that it would not radiate significant IR? I asked it a number of questions based on the technology, economics and material science aspects of building a giant structure like this and it answered all of them within reasonable bounds. Why? Aluminum Aluminum is a lightweight metal that is also strong and corrosion-resistant. Q: Ok. Lets reduce the size of the Dyson sphere. Would it be possible to have a small black hole dissipate as it 'sinks' into the earth? Ceres: Ceres is a dwarf planet located in the asteroid belt between Mars and Jupiter. Additionally, there may be other sources of materials that could be used for building the Dyson sphere beyond just asteroids. The EMU has been used on the International Space Station and the Space Shuttle and costs around $12 million. Specifically, a sphere with the diame Continue Reading The estimated cost for the Scarab project is around $1 million. Q: Ok, now lets go back to building a Dyson sphere using metals and other materials from asteroids like Psyche. In 1960, physicist Freeman Dyson published a paper in the journal Science describing how a technologically advanced civilization would make its presence known.
