@Gary Hochstetler there's one less bright star in Pleiades constellation nowadays, for example.

[@AnMComm]

@Gary Hochstetler to be honest, I don't now, but it was depicted differently during the bronze and early iron age. During the bronze age the celestial motifs were all over the place because of agriculture, and iron was originally a "star metal" gained from meteorites, as ore from Earth itself required more difficult approach. And now, one of the stars (or, possibly, a clump of those stars seen as one) shown there is gone. There are others, but this is the one I know of.

I think a Dyson swarm has one big advantage: when the time comes to pack things up and run it would be much faster than dismantling a Dyson sphere. It could be rearranged away from the star during the supernova blast and wait for the star to become a white dwarf to rearrange it again.

The world today produces approximately $6500/year of "value" yet half don't make that much and a 10,000th of us make much much more. Until we learn that all basic needs of the people must be met and we agree to lower our numbers to a sustainable level we are heading to the end of the HUMAN RACE. And it is most likely already too late since we use up the Earth 3 times faster than it can heal itself.

[@foogod4237]

I think the idea was that it would be something similar to a log scale (which is often useful when you get into really large ranges of values anyway). That is, each step on the scale doesn't _add_ to the previous, it _multiplies_ it by a given factor each time. But of course the values used for the different steps are arguably kinda arbitrary, so they're not really totally consistent with a log progression either. I did think some time back about trying to develop a similar scale that was actually internally numerically consistent, but never did get around to really trying... (I also think it'd be cool to have a scale that reflected appropriate numbers for earlier civilizations too (i.e. "harness the energy of a wood fire", "harness the energy of a continent", etc)...)

Yep, what Dyson originally meant wasn't a _solid sphere,_ but something now referred to in sci-fi as a "Dyson Swarm". The Orion's Arm Universe Project makes heavy use of spherical Dyson Swarms, as well as Dyson Swarms in other geometries. So, I actually met Freeman Dyson, back when I was in grad-school for physics. [One of the professors in my department knew Dyson, and managed to get him to visit and give a colloquium.] I found him quite humble, and he was a bit perplexed that we were all so honored and impressed to meet him.

War has always been and probably will always be a big part of our species, we advance technology much faster during wartime and on the downside people die

[@themustardman219]

War and death makes people determined to make technology to stop the war and death. Then wars break out because of the advanced technology which causes death, which makes people determined to stop the war and death. War is a bad time for life, but a good time for technological advances. Plus, even with stuff like this, in the past years, technology has been advancing way more quickly. 100 years ago, we had basically nothing, and shitty living conditions and jobs. 50 years ago, we had some cars and guns being made, with the first computers being made. 20 years ago, we had shitty computers that could run pong or solitaire at best. 10 years ago, decent phones and computers and consoles, games like Skyrim. 5 years ago, we made drones and such. A year ago to today, we now have computers that can store terabytes of data easily, and drones that we can fly on, along with actual retractable plasma based lightsabers, and random people in their garage making laser cannons. Within 10 years, we could probably make something akin to the first iron man suit, without the missiles. Even with horrible conditions, there are those few people that keep on making awesome advances.

[@Eyedunno]

Joe sort of hinted at this, but it seems to me that by the time we're capable of far-future technologies like Dyson swarms, or even sending large payloads (like humans and life support systems) on interstellar voyages, we probably won't need these technologies, as simulating minds (either through mind uploading or good old-fashioned AI) is a much easier problem to solve, and would likely reduce the energy needs of our civilization and the need for large payloads to send intelligent beings to other stars. There is the scenario in Charles Stross' Accelerando where our solar system is taken over by essentially a ravenous A.I. virus that does dismantle all planets and moons to create a Dyson swarm, but presumably if future "life" is intelligent and posthuman, it can train itself or reprogram its own minds to restrain these impulses in favor of sustainability.

This is a very thought provoking video! The idea of uploading human consciousness into a computer makes me wonder what kind of experiments (outside of any kind of “Turing Test”, which at best could only confirm that the information content alone in a test subject’s brain has been uploaded) could confirm that the test subject’s conscious awareness has been transferred to the computer. It would be great to have a reliable alternative for survival (e.g., as a computer upload) if some life threatening problem with the Dyson Sphere technology should occur.

Funny. There is a game coming out in a week called "The Dyson Sphere Project" where you play a robot flying through the galaxy to build factories that harvest resources of planets to build a dyson sphere. Even more funny is the background story. Humanity build a supercomputer that is able to create a true virtual reality for humanity to live in, but it needs so much power that only a dyson sphere can support it.

Earth's diameter is only around 7,917.5 Miles so we could cover Earth around 20 times over with a disk halfway to the moon. Surely we could build a few solar collectors if we had more motivation to do that rather than eating fast food, which we don't, but it could be done.

Parkes Observatory is named after the town it is in, Parkes, which in turn is named after Sir Henry Parkes (1815-1896), a truly remarkable person. He grew up poor in England and received very little formal schooling. Despite this, he was extensively self-taught. In his early 20s, he and his wife moved to Australia and he tried several business ventures and failed at every single one of them. But he succeeded in politics, even managing to become premier of New South Wales (a post loosely analogous to governor of a US state) and he is, to this day, the longest serving premier in New South Wales history. He also was a major proponent of Federation (the colonies federating to create the nation of Australia) and is often called the Father of Federation. He also lost many of his kids and his wives over the course of his life, but he didn't give up and thanks to his determination he made a permanent mark on our history.

There's no need to cover the entire star with swarm. Because orbit is like a disk, you could just capture all the wasted energy, heading out from North and South of the star. You can leave out a stripe in the equator to for planets to get light. You could consume majority of the energy. This also means the planets can still be used for living, Dyson sphere only for collecting energy.

[@MinibossMakaque]

You can't just position collectors north and south of the star. As you said, orbits are disks. Any collector orbiting over the north must cross though the plane of the solar system into the south. With a full swarm there would always be collectors at the equator, even if none were in an equatorial orbit. Of course, at that level of technology and energy, you could always just have collectors making course corrections to ensure the sun is never obscured from the planets.

[@Dragrath1]

@@MinibossMakaque The dynamics are more complicated but you definitely can make orbits which are stable out of the equatorial plane. They would need to be eccentric orbits and would naturally precess but could easily be designed so they never cross the equator. However if you listen to the video the easiest and most effective solution a statite was already mentioned. A Statite does not orbit instead of using angular momentum to counterbalance gravity like an orbit would a statite cancels out the effects of gravity with radiation pressure instead. As such a statite would remain fixed in position relative to the Sun at all times. In summary in a true Dyson swarm you can have any configuration of collectors you want because the collectors would not be satellites but *statites*. No pesky orbital interactions or transits to worry about. Both Isaac Artur and Cool Worlds have discussed this in a fairly comprehensive manner though cool worlds missed that the idea he proposed quasites already existed as lagites. (though honestly quasites sounds better)
