[@SirReptitious]

I find it strange how people love to cling to the thought of Dyson spheres/swarms as the "ultimate" form of energy generation. We now know that water is extremely common in the universe, and so I find it infinitely more likely that advanced aliens would use fusion reactors since they would have a practically unlimited source of hydrogen.

[@musaran2]

The elephant in the room is that a star IS a fusion reactor. The biggest one could build.

[@TheGodCold]

@@musaran2 Yes, but theoretically it would be much less of a hassle to just create a "homegrown" fusion reactor than to construct a megastructure around your star (which will also be a great way to show the entire galaxy that you are here) and to transport that energy to your planet

[@fernandogajo8800]

Interesting proposition. In my sci-fi game scenario, the Dyson Swarm was built by Earthlings to power the "Metaverse", after the Titan Moon Server started to run out of Data Storage and Processing power. You see... In this setting, humans use quantum copying of themselves to upload their entire selves into the virtual universe, and once they are there, they won't ever die. So... Human population was beyond the quadrillions by then...

[@daveswietlik6291]

@@musaran2 thats like saying "why use internal combustion engines, we could just burn gasoline in a pit and collect the radiant heat and light energy" Your argument does not account for efficiency losses in energy capture. A star isn't exactly the most efficient way of extracting energy from fusion in the application of harvesting that energy for other purposes.

[@toasteddingus6925]

Well sir turns out that yes it's readily available but there's more than a few problems with using it huh? Compared to the rather easy nature of building a Dyson swarm when most of the tech needed is orbital manufacturing

Advanced aliens or AIs are often imagined to be extremely, inhumanly patient, long-lived, and far-sighted, and willing to wait thousands of years for results from their projects. But it seems like, though immortal, they might live fast, at nanosecond scales, and have extremely, inhumanly little interest in the remote and irrelevant future of next month.

[@nagilumx6715]

There's always the ASSUMPTION proselytized by the Transhumanist community, Twirlip, that "evolution," civilizational progress, or whatever one chooses to call it, inevitably culminates in electrochemical beings changing themselves into electrochemical ones. I don't accept that as automatically true. What about those who develop their minds to such a tremendous extent that they become psychokinetic? Is that really such a far-fetched idea? Logical possibility doesn't seem to forbid it. Ridiculing skeptics used to think it nonsense to even think about flying. Until some brave soul attempted and proved it could be done. They said the same against supersonic flight, manned rockets, and journeys to the Moon. Until each was proved by a brave soul feasible. Today, certain brave ones won't accept that Faster Than Light drive, time travel, controlling machines with the mind, or Artificial General Intelligence are impossible. They're doing everything to prove the obstacles to achieving each of these challenges can be overcome. And they're taking concrete steps to prove these possible. Now, taking our exploration of this to the next level, we must accept that the primary reason humans have used instrumentalities is because each either enhances an ability our bodies can produce, or give us new ones they cannot. Logically, then, once we CAN do so with our minds themselves, we wouldn't need instrumentalities any more. How so? Well, we know electromagnetic fields influence nature's other forces somehow. And brains produce, albeit weak, EM fields. Scientists, in fact, say that ours might be capable of producing, beyond the Gamma level, up to 200 Hz. Wonder what might happen if we found they do? Now, what if superadvanced civilizations, in time, discover that (1) their brains can produce such frequencies and (2) the quanta of this mental energy can interact with virtual particles within the Zero Point layer of Spacetime? And, finally, what if these beings establish methods--perhaps technological--for enhancing the effect to the extent that they can quite literally transform what they imagine into real objects! Can a genuinely logical person rashly declare this an impossibility? Not really. Blasting out the same tiresome words, "Where's the evidence?" does no good. What they should do is what any really logical person would: LOOK FOR IT. Design hypotheses, theories, and devices which enable you to detect the known and unknown particles, forces, fields, and interactions which could define and verify these abilities could be realized. I tell you: Those who fearfully refuse to do so while continuing to bitch, "There's no evidence!" are just holding us back from the real advances we might--no, that we MUST--realize in order to survive in what could prove a highly challenging Universe or Multiverse. Those who bravely refuse to be deterred by skeptics and take the bold steps needed to elevate us to a superadvanced future.

Controlling machines with our minds is something that is already happening all the time unless you think that the body is anything more than a glorified mech suit for the brain and nobody says that this is physically impossible anyways. AGI: There is no reason that should be impossible since after all *we* exist so it would only make sense if intelligence that is as smart as us is able to be artificially created. "How so?

Why do i get the feeling you are soon going to tell us some New Age pseudoscience woo BS ? And yes out brains do produce EM fields but that does not make telekinesis possible and tons of other things in the world (Including the world itself) produce EM fields far stronger than anything the mind can produce. "Now, what if superadvanced civilizations, in time, discover that (1) their brains can produce such frequencies and" And what if they can ? There are no applications for such a thing let alone applications that blatantly violate physics like telekinesis. "the quanta of this mental energy can interact with virtual particles within the Zero Point layer of Spacetime?" www.scifiideas.com/technobabble-generator/ "And, finally, what if these beings establish methods--perhaps technological--for enhancing the effect to the extent that they can quite literally transform what they imagine into real objects!" What is perhaps technological even supposed to mean ? Technology is the only way we can manipulate the enviroment with besides out own bodies. And us magically wishing things into existance is complete BS that fits better on New Age nonsense sites than the real world. "Can a genuinely logical person rashly declare this an impossibility?" I just did so. "Blasting out the same tiresome words, "Where's the evidence?" does no good" The Wright Brothers had to actually prove that they made a machine capable of powered flight you know, Einstein had to show that his theory could make accurate predictions of events and explain the things we have observed so far. " What they should do is what any really logical person would: LOOK FOR IT. " We already have and we found out that telekinesis is impossible and so is us magically materializing things into existance by thinking them. "Design hypotheses, theories, and devices which enable you to detect the known and unknown particles, forces, fields, and interactions which could define and verify these abilities could be realized." Such hypothesis would violate all of established and well known and studied physics and they would never become theories unless they have enough evidence supporting them. There are no unknown particles, forces or fields or anything such thing that we don't know of unless proven otherwise. People have tried to verify if those magical abilities you described actually exist and we have repeatedly seen time and time again that they do not otherwise someone would have already signed for and completed the One Million Dollar Paranormal Challenge before it was ended in 2015 but out of the 1000+ people that signed for it over the course of decades all of them where debunked and exposed as frauds and scammers. "I tell you: Those who fearfully refuse to do so while continuing to bitch, "There's no evidence!" are just holding us back from the real advances we might--no, that we MUST--realize in order to survive in what could prove a highly challenging Universe or Multiverse. Those who bravely refuse to be deterred by skeptics and take the bold steps needed to elevate us to a superadvanced future." You and your kind are the ones making this absurd nonsensical claims about humans being reality warpers. The burden of prrof is upon you not science.

[@HaveYouTriedGuillotines]

@@nagilumx6715 The problem with the idea of psychic energy is that there's no identifiable energy to match such a phenomenon, and in fact our ability to identify what energy is doing exactly what doesn't leave much room for such a thing to exist. We know that the brain is a bunch of electro-chemical impulses, and those impulses, even if we don't really understand the minutia of it, are well accounted for in terms of energy economy. In other words, there isn't, for instance, a bunch of electrical energy that just seems to be disappearing into the void in an unexplained manner, to which one could suggest is powering some kind of psychic phenomenon. There is the absolutely tangential _possibility_ of some kind of dualistic existence, wherein there's more reality that exists in parallel with our own reality, with some kind of unexploited potential, but that still requires... Y'know... Proof. You'd need some kind of definitive demonstration that there are fundamental forces of nature as of yet completely unseen by us, and discovering such would be a discovery on a level even more extreme than that of the Higgs Boson. That isn't to say that reality manipulation is out of the question, but a species that advances to that point would likely do it through a method we're already familiar with: Tool use, augmentation, etc. I do think the sort of stuff you're suggesting might be possible, I. E. figuring out how to "pinch" the fabric of space and create matter from "nothing," but it wont be done by some kind of bogus "psychic" energy. But rather some unfathomably advanced technology based off an understanding of physics we're not even close to yet. On a side note: Something people forget is that biological life is really just a machine made out of flesh anyway. We have servos, computing clusters, lubrication, etc... All within our body already, it's maybe just not the most efficient design. Hell, every cell in our body contains a miniature power plant. Who's to say we couldn't engineer biotechnology that straddles the line between machine and lifeform with all the strengths of both and almost none of the weaknesses? I question the idea that an advanced species ever needs to truly give up its primordial uniqueness to advance into the stars. It just needs to be... Tempered, a bit. Tweaked, improved, upgraded, bugs ironed out.

[@livefire666]

Perfect and concise, awesome as always John! Also just wanted to point out that a "Louver Arrangement", "Shkadov Thruster", and a "Nicoll Dyson Beam" could easily be all incorporated into an energy collecting Dyson Swarm. Dyson Swarms really are a multi-tool of usefulness in space engineering, and why so many scientist think we should see them. Its also estimated that you would only need a 10 percent Dyson Swarm on our star to get the energy needed to produce endless amounts of "Kugelblitz Black Holes" which are more efficient Dyson Swarms if "Hawking Radiation" is correct. So we need the ability to detect 10 percent complete Dyson Swarms and up to know there arn't any in our galaxy or others.

18:55 Putting aside the wildly different outlooks and philosophies that any alien civilization would have compared to us, I think alien civilizations each comprise of a vastly diverse set of individuals: some ambitious, some nihilistic, some nice, some cruel, some smart, some dumb, some who wish to learn and explore, some who think they have all the answers. And a number who are perverted or outright insane. So in that sense, they would be a lot like us I think.

A smart person in Medieval Europe would have had ideas/imaginings of life in the future, but no real clue as to how we would be living today. Thus, judging other interstellar civilizations; indeed, our own future from the narrow understandings and viewpoints of where we are at this moment in time, brings into question the pretentious, ignorant, wankers, who say things like replicator and teleportation technology will never be possible.

[@chrismusix5669]

Even if there were a civilization comparable to our own as near as the Alpha Centauri system, could we even detect them? Even at that relatively short cosmic distance, would even a single radio transmission be detectable from there?
