If it looks like a duck, quacks like a duck is probably just some type of interference cloud we're not familiar with
Lol.
ITS A WITCH!
In medicine, it's "If you hear hoofbeats, think horses, not zebras."
@@randallpetersen9164but his point is that it sounds like hooves, but it’s not a horse or a zebra. It’s dust clouds.
Space Duck !!!!
dust around star, sounds like a job for a certain vacuum cleaner
And this time, it's really a VACUUM cleaner
@@b.s.7693😂
Humanity goes after the critters making the dust, uses The VC's.

Deploy the Dyson Space Dust Consolidating VacPrinter
Many years ago I met Professor Dyson in Cambridge MA. Long story, but I was attending his talk, saw he was lost, and introduced myself. I then escorted him to his talk, that he thankfully didn't miss :) I was given a front row seat in thanks lol. Also got to meet Professor Charbonneau of Harvard, we discussed planetary search methods and such. Was a fantastic experience.
You're a luck dude to have met two such minds !
@@jerryfolsom886 that's not luck, you'd have had to be in america for that to come true, and that's a cost not many decent people are willing to pay.
You didn’t meet anybody except yourself. The mind is just a receiver of information. How do you know the things you know? An empty vessel for consciousness that has no form.
Rule number one of space exploration: It's never aliens.
@@Seigensi Hence, he is in a lucky position...
The amount of materials required to build such a structure would in itself seem to present an insurmountable challenge.
That might be true if the only occupants in this place are humans from planet earth
Not for a lifeform that is capable of harvesting resources from various planets.
Even our smaller asteroid belt has significantly more raw materials than would be necessary, so if any advanced civilization were out there mining asteroids, they’d have more than enough.
I imagine that a civilization that has the ability to build such a structure would likely find a way to harvest materials. If our tech made travel and mining in space feasible and profitable we could just cannibalize Mercury and refine it, it’s predominately metallic.
with billions of years to do it, as long as your progress is constant and maintained... the only impossibility is the fermi paradox, not the amount of materials - since everything is very aboundant including energy
That Dyson guy can build anything..
Got a good chuckle out of me on that one
Not just vacuum cleaners!
But he is awesome on anything vacuum related
@@ericv738suck! suck! suck!
"Sir" Dyson to you, peasant.
I get home from school at basically the same time Anton posts videos, so watching them as soon as I get home has become a ritual of mine
ALL HAIL THE HOLY ANTON
I would have loved to have this resource available when I was at school. I am older now, and grateful for this fantastic information 40 years later!
A swarm of solar panels around the star would be easier to set up and maintain
@@osmosisjones4912 Or just invent fusion and be done with it. Seems the Dyson sphere assumes fusion is impossible, which, if so, is bad news for planet earth and greenhouse gases..
@@raylopez99 I see it as more of a reason to believe Dyson swarms aren't very common. If anything, perhaps building a fusion reactor as powerful as a star is more expensive than making a Dyson swarm, but who knows
The number of planets you'd need to completely mine out just to create a single ring around even a tiny star would be crazy. It just seems like a silly idea.
And what the hell would you need all that energy for?
@@mortyjames5897In pre-history, hunter-gatherer humanity used about 6,000 kcal/person/day just to keep itself warm and fed to hunt another day, in the 1800s that amount had surpassed about 70 to 80 thousand kcal/person/day due all of our commodities, growing food, transport, housing. And now humanity uses about 0,23 Mkcal/person/day just to keep our planes, commerce, transport infrastructure and world going. Our population might as well double in size within the next 200 to 300 years even at a modest 1% rate, and so will our energy needs to feed, transport and house all this people.
It isn't far fetched to assume, following this trend that an advanced civilization with like 10x our population sized would need like 100x or 1000x our current energy usage just to keep their infrastructure running. At this sorts of scales, plain solar power on their planet would take a huge space and a huge toll on the planet's energy budget (remember that weather and life all depends on the energy coming from the sun), whereas there is a lot of sunlight that wouldn't ever reach the planet which is lost to space, that energy is the energy a Dyson Swarm would tap on.
I think that if a truly advanced civilization would use other forms of energy such as zero point energy. Zero point seems much more efficient than constructing a gigantic Dyson swarm
@@nigelbhebhe2805 we are considerably advanced but nuclear power is just steam power at the end of the day. A Dyson sphere considers a scenario where such sci-fi magic such as zero point energy, wormholes and FTL travel hasn't or can't be achieved.
Why build giant structure around a big ass star when you can build a small star in a realistically sized chamber?
The 'total sphere' type of a Dyson Sphere, was used in a Star Trek: The Next Generation episode 'Relics' 1992. Where they say that they did not detect the sphere before, because all of the stars energy was masked by the full sphere around it. So while less likely, it is possible, we are missing some giant space structures, because they are not emitting light/energy that we can detect, at all.
That is not allowed by thermodynamics, without radiating away waste heat the interior would continuously increase in temperature.
It could still be detected by warping and blocking light from stars and galaxies.
@@VolkerBraun0 and the fact that the amount of matter required to spherically encompass a star, even as close as 1 AU is well, far beyond the mineral wealth of any stellar nursery's output. Additional matter would just go into gas giants and more stars, not be sitting around awaiting the day some species decided to make a gigantic ball out of it.
Any other channel would use a clickbait screaming title like: DYSON SPHERES HAVE BEEN DISCOVERED
But Anton? Nah, he is honest. Such a good place to get worthfull (nerdy) information from!
another channel would say "terrifying discoveries in nearby Dyson´s Sphere prove aliens are coming to eat us and terraform the Earth. " lol
@@nextlevelenglish5858 Pretty much.
I think it's funny that you said terraform Earth. As if Earth wasn't earthy enough.
If only we could find out how to infuse this type of intellectual honesty into our leaders.... Depressing that it's becoming a rare quality, but make me appreciate Anton more.
@@gottabekidding8626 They would have to admit how much they don't understand while moving forward with curiosity and shared values. Paradise.
I think I may have blocked fifteen of those channels already, but they keep popping up, even in different languages. 🤕
I just want to take a moment to remind Anton that he, too, is a wonderful person. 💜
I second this! ❤❤❤
Simps
A-FRIGGIN' MEN!! Dude is a global treasure.
Yeah, Gayton Petrov is one of the bloggers ever made.
Hello everyone. Love the channel Anton!
So I think these anomalies are most likely swarms of material going around a star where planets didn't form right or something entered the solar system and disrupted things to the point where you just wind up with a mass of orbiting objects. Just a thought
O also think this. I doubt that in practice any civilizaifon out there including us will ever be able to construct a dyson sphere
I remember when Anton was just a small dwarf in the corner of the screen.
The reason for this video is Anton wanted to use all the awesome art floating around for Dyson spheres.
He asked Issac to borrow some 😁
it turns out the unified field theory is that the universe conspires in its workings ultimately to give us the best of all possible anton videos
8:23 Look out, Anton! There is an alien sneaking behind you, to stop you from telling where they live!
If a number of such stars were found in close proximity to each other, that could be more compelling.
Someone correct me if I'm wrong, but I believe all the candidates found were actually relatively close together?
I'm sure you're correct, I was reading a few days ago that there's a cluster of about 15 F and G type stars near Tabby's star that all seem to have the same unusual dimming pattern - they're called slow dippers. While the dust cloud explanation is very plausible and likely, I know there's still some caveats that haven't been confirmed/ruled out that would increase the star's and the other candidates possibility to be showing signs of life. There was also a study that looked for laser light emissions from stars as a technosignature and Tabby's star was the only one that returned a detection, though the study ruled it to be an errant cosmic ray - the universe has a great sense of humour - @@lcvvcl2654
@@lcvvcl2654 yeah recently there were about 53 all together like this in our own galaxy
Dont forget about the blinking stars that were flashing in sync and the various signals SETI has found. I have no doubt that we have actually found aliens already they are just too far up their own behinds to spend more time looking into them.
Yes. If a network of spheres where to be discovered, we could theoretically triangulate the location of the originator system. Just saying.
Dyson: "We have the most powerful vacuum cleaners ever!"
Black Hole: "Hold my beer!"
Yet another video proving you're one of the best on this site for communicating new scientific findings without unnecessary hype or clickbait! You stick to the facts, give as much context as needed, note the limitations and remain skeptical until the evidence is strong enough to reach a conclusion. Thanks for all that you do, Anton!
You are the only space/ science channel I trust, everyone else likes to clickbait and say that "NASA/ JWST JUST FOUND DYSON SPHERES!!!" At least your video title has a question in it, almost like is it really? I appreciate that you actually do your research and tell us all other most likely reasons for everything.
They'd probably add "terrifying" too.
Anton really is the best.
Anton is great. Arvin Ash is pretty good too.
you distrust startalk with neil degrasse tyson?
Insert AI thumbnail picture of Michiko Kaku or Elon Musk crying. "we LIED!"

And what are we? Proof?
They always try to disprove instead of prove. Thats not science thats being hardheaded and nhilistic.

Yeah, haha.
0:51 Anton, it would have been nice if you included the name of the author here, because he is worth mentioning. The author is the British speculative fiction author Olaf Stapeldon who together with another British author John Wyndham formed the bleeding edge of the genre in the 1930s, at least until the advent of the Golden Age.
Stapeldon wrote a lot of groundbreaking novels, Star Maker, Last and First Men, Odd John, Sirius and so forth. His work has aged extremely well and inspired almost all of the Golden Age greats. His books are definitely worth reading!
That's as click-bait a title as I've ever seen Anton use! I'm totally in.
He needs to make an income. He doesn't have mom and dad to provide them housing like most of his viewers.
@@glorymanheretosleep Oh, Anton's a credit to humanity. I was just poking fun.
That’s because he’s generally a wonderful person
@@glorymanheretosleep he has a child to feed
Eh, I actually find a lot of Anton's titles click-baity. Which is totally fine, because the quality of the videos themselves is always impecable and not sensationalistic.
Olaf Stapledon was a pioneering philosopher and science fiction standout. Amazing freedom of mind.
Odd John, good read.
One of the best signs of megastructures in the galaxy are the ultra-fast spinning neutron stars. Their timing is so precise that we've already used them as markers on the golden record that's on Voyager, to indicate where Earth is. They are almost perfectly laid out to act like galactic navigation beacons, spaced evenly throughout the galaxy arms.
YES! My favorite book of all time finally got mentioned in a popular video discussing the cool science fiction idea it introduced! Thank you for giving Olaf Stapledon his due.
Betteridge's Law of Headlines: "Any headline that ends in a question mark can be answered by the word no."
I so called that it was going to be a dust cloud. Lol.
The name Dyson gave it away…
These always seem to turn into some kind of "dust".
Nanite dust 🤔
to dust ye shall return
Because the concept is dumb. Like making a oceanline thats oar powered.
Come up with a better concept genius
From dust you came, to dust you shall return 🫣
You have very good English speaking, I appreciate you taking the time to pronounce things correctly. Very nice video I learned quite a bit! Thanks!
How very interesting! Your channel just keeps getting better each time. Bravo! 😊
What if every Brown Dwarf star was a main sequence star with a Dyson Swarm?
What about Jupiter though
Not a Brown Dwarf last time I checked.
What about at the center of every plant?
You can't tell me, that with all that pressure and heat, that the center of the earth is Molten nickel iron.
How do they classify planets? By how much radiation it gives off. That's why Pluto isn't a planet anymore.
what causes radiation? Fusion.
And there's also sonoluminescence.
I think the universe is so vast that everything we can imagine, exists and much more that we haven't even imagined yet.
Fact is stranger that fiction. Mabye even stranger that That!
Not sure about mermaids, though.
"I think the universe is so vast that everything we can imagine, exists and much more that we haven't even imagined yet."
Based, I also believe this.
It's actually the opposite. The universe is so vast that even traveling it is bordering impossible. A Dyson ring would require more material than dozens of solar systems even contain combined.
@@banriswirl6414 A Dyson ring is such a preposterous idea. How long to build and how expensive? Millions of years and a trillion trillion trillion credits. Then you need to do repairs on the early builds damaged by space debris, etc. If a civilisation is running out of heat and power, that's the last thing they're going to spend time building. Better off using geothermal and cutting population growth. Stas also expand as they age, so the sphere would have to big enough not to be swallowed up, and then the stars disappears anyway. "What a waste of time and money!" is an understatement.
We can’t figure out the 9th planet issue but we can observe Dyson spheres hundreds of light years away…we need to focus on our system first
The funny thing is to me that Dyson Spheres are even seriously discussed as an option.
Expect the builders of Dyson’s Spheres/Swarms to camouflage the megastructure with the leftover remains of the orbiting building materials (dust ore, diverse construction debris, etc) so not to attract the unwanted attention of Fred Saberhagen “Berserker’ robots, si-si 😂
Berserker/Saber haven reference...gotta love it, good series!
Or the Reapers
Or said material is actually being used to construct. I mean, relativity still needs to be taken into account.
I wonder how they'd deal with solar wind & CMEs
Olaf Stapledon's "Last and First Men"(1930) is the story of humanity's future for 2 billion years until extinction of the Last Men - the 18th (if I recall correctly) human species who have a form of time travel and can communite with past humans - on Neptune. "Starmaker"(1937) has the narrator being able to travel in time and space, observing vast number of intelligent species, and the failure of many of them, and it has a proto- Dyson's Sphere. "Last and First Men" also prophecied the death of princess Diana, sort of. ;)
Insane that it was written back in the 30s. The concept of aliens was probably unimaginable at that time, I bet.
@@nigelbhebhe2805 "The 2nd century writer of satires, Lucian of Samosata, in his True History claims to have visited the Moon when his ship was sent up by a fountain, which was peopled and at war with the people of the Sun over colonisation of the Morning Star." Voltaire wrote about people from Saturn in his 1752 novella Le Micromégas.
But these aliens were essentially human, they couldn't imagine other intelligent lifeforms. Non-human aliens only appeared in fiction after Darwin's On the Origin of Species in 1859. For example, the Martians in The War of the Worlds (1898).
You really cracked me up with the James Dyson joke. Brilliant. Now I'm thinking, Dyson Sphere or Dyson Ball? 😂
At least if they have Dyson spheres around planets, they are unlikely to want to bother with us. Of course, there is that little manual, "To Serve Mankind."
For Dinner 😁🍽️

Anton I hope you are well. Your videos are amazing all of us here, your viewers appreciate dvery minute you put in. Thank you sir.
I haven’t been watching as many videos recently so I might not know, but I feel like the quality of your videos have improved and I love it.
"Misstuh Datuh, could this be a Dyson Sphere?"
"It fits the known parameters Captain."
Lmao Anton, you got me good with the opening to this video. I was doubting myself, like: "wait, wasn't it Freeman Dyson? Why is that name popping into my head?" 🤣
Of course they could be Ringworkds - hat tip to Larry Niven
Your channel should be mandatory for High School, I would have loved this level of knowledge and curiosity!❤
That would have been over 50 years ago, but……😊
50 years ago my dad bought me a Pong TV game. He set me on the right path to becoming a software developer.
Yep… back then we had to read those heavy bricks made out of paper (what were they called? Books?) in order to get some knowledge…
@@giannappleOK grandpa. Did you make the papyrus yourself after picking the reeds along the banks of the Nile?
Absolutely fascinating stuff, you are such a treat to listen to!
I’ve been watching this guy since I was 12. I’m now 22 Thank you for growing up with me Anton
I appreciate your passion for this topic my friend.
I read through it. They put in a LOT of work to narrow these down. Well done
I would hate to meet the kind of civilization capable of building a Dyson sphere....
They'd probably be AI empire or just a hedonistic beyond needs society
Yeah definitely robits 😂
Hive colonies with a queen and disposal drones
Why? They’d probably have to have evolved to be peaceful just to survive long enough to cooperate on such a feat
@@geoffgunn9673 The queen is disposable too, at the mercy of the workers, her daughters. It's a hive mind, not a monarchy. (I'm a beekeeper.)
I'm glad you mentioned Star Maker. Dyson, if I remember correctly, gave the book credit for inspiring him.
To build a Dyson sphere would require materials from millions of planets.
Wasn't there some sort of association with the locations of most of these stars? Like statistically they were too close to each other for something that should have been distributed randomly?
Makes sense if it’s from an advanced interstellar civilization that is beginning to spread across the galaxy 🤔
I figure that that'd be the first thing someone would say about these studies, until it's realized that they only looked at a single section of the sky due to lack of funding. I can't imagine they had enough money to rent out the telescopes they used for longer than it took to take a few photos.
Only if you think random means equal
Yes! Jean Michael Godier made a fantastic video on this a day or two ago, and many candidates are in a cluster.
@@commode7x These papers are analyzing datasets collected over the course of years from multiple telescopes, they weren't only looking at a single section of the sky. Further, the candidates are not only in the same region of the sky as viewed from earth, they are actually close together in 3D space.
Lol the Dyson joke was great 😂
Последнее время в космосе находят много чего, что «should not be there”. Благодарность за выпуск!!!!
"Star light, star bright. The first star I see tonight. I wish I may I wish I might. See a Dyson sphere shining bright"
My guess is that by the time a civilization reaches the capability of building a Dyson Sphere,
they will have discovered another source of energy that would be far easier to attain.
Tbh we already found it, its just a matter of being near or practical enough, blackholes are way more energetically efficient for megastructures than stars due to being easier to build and make more energy, stars are good for extraction of resources for fusion with stellar lifters :D
Discworld or Ringworld, or Dyson?
I've always thought aliens would move away from stars, to get away from the radiation, so most aliens live in the dark void between stars, or even between galaxies.
Eh, I think I would disagree, not to say better sources aren't out there but I think we could do a Limited swarm at current technology, and maybe you need large power output b4 you harness vacuum energy by boiling space or something.
@@juhajuntunen7866 Dyson swarms for starters, and make a birch world for hyperstructures
Remember guys, it's never aliens
Yes
except when it's aliens
@@hydroids can't wait.
Not yet anyway….
I refuse to believe its aliens till one vaporises my me into atoms.
We need to call Planet Spaceball, so that we can hire Megamaid to clean up all the dust around these stars.
Dyson spheres are such a funny thing for people to take seriously. The amount of material you'd need to build a structure large enough would require more energy to get it in position than you'd ever extract from the star.
Any star that doesn't neatly fit our preconceived notion of stars must be a Dyson sphere.
Makes exact prediction of Techno signature. Gets exacting hit. no conclusions drawn. Science fans already angry at the data. lol
Hey, we should at least look a little harder at those stars than the ones that do fit neatly, no?
Dust around the star. Again.
That got ruled out for all but 7.
Dusty aliens
i guess thats why we have that other Dyson Guy..

I'd recommend using Head and Solars.
@@bigpauliep6992 !!! LOL!
I love his theory... it’s one of my favorite Star Trek episodes. Thanks for the academic perspective.
Any civilization with the resources, infrastructure, engineering, and tech to build a Dyson sphere would not need a Dyson sphere.
They should use the satellites to look for intelligence in our politicians.
Waste of time and money. Nothing to be found.
Astronomers not necessary but if they want to find a brain they need a proctologist to look up their asses
Whoa buddy, that would be way off. We dont have sensitive enough equipment yet to detect anything that miniscule
They're not stupid, they're actors.
This one was kind of fun to think about! 😊 I guess because I'm into Star Trek!
That episode of TNG with Scotty is one of my favorites. 😅
I can totally imagine a star covered and surrounded in Dyson carpets cleaners 😂

A structure that can move a solar system?
That is a cool concept. I never heard that one before.
One of the many reasons I love this channel.
Then you might be interested to look up on the Kardashev scale. Very interesting.
The cool thing is that either we'll find ETIs, or we'll find some previously unknown aspect of astrophysics. No bad options.
I have a feeling that we will only achieve Dyson sphere AFTER we learn to convert energy to matter. Without that achievement, we won't be able to harvest enough material to build the structure. In the process of this, we will likely harvest a significant amount of the target star just to build our energy harvester.
Just for a millimeter thick energy absorbing membrane, we would need more than the mass of Jupiter to fully encompass our star.
The practical plans are dismantling mercury due to its solar rates for solar panels to fuel factories, mining operations and electromagnetic launching to the sun due to being near and low gravity and making a dyson swarm instead of a rigid sphere
I've never heard it would be that much material. The estimates I've heard are 1 or 2 terrestrial planets.
Ok, so I did the calculations . At earths orbit 1mm thick shell will be 10^28 mm³, or 10^19 m³. The earth is 10^21 m³, so a shell that thin would only be 1% of earths mass.
But 1mm is pretty small, if it's 1m thick that is now 10 earths mass.
@@David_Last_Name and the swarm would probably be way closer than earths orbit so even less material would be used
@@teaboy8362 Mercury is the perfect candidate. Simply use a self replicating machine swarm to turn the entire planet into raw materials and use it to build the Dyson swarm/sphere.
Thanks!
for a higher class civilization, construction of a dyson sphere could be relatively easy. its crazy that people thinks its impossible.... with the ammount of matter out there and assuming its a technology we have no conseption over, a dyson sphere could be a normal thing for such a civilization. the sphere doesn't have to be solid. I could be millions of relays scattered around the star then using some kinda of energy field linking them up with each reley being say 5 miles apart they could do it. people assume a dyson sphere is a solid construction, but thats a waste of matter and time. they could do it with much less matter.
Edit, I just got to the part where he mentioned the dyon swarm. good job Anton! this is to me the most logical dyson sphere.
Skeptic here. Star winds, electromagnetic field, revolving comets and the amount of material to build that structure are among the to things to consider for that sphere to even partially exist.
It's either a Dyson sphere or Galactus just chewed up and spit out the dusty bones of another planet - the planets corpse is now blocking its sun.
A system with collided and completely disassembled planets, where one of them was captured from a galactic space, and which orbited in an opposite direction
Jumping to conclusions is only good when it runs contrary to the possibility of a novel discovery.
Love science folks. So sensible
@@sethjensen2291 These are comments to promote the channel =) We can only type on the Internet. Some words which we can shape like an 'idea'. Everything is good.
There are LOOOAADS of other possible explanations that should be preferred over something like the Dyson sphere fairy tale.
Just ordered another t-shirt from you. Love your vids. You're a wonderful content provider... person.
"for all we know, somebody might be trying to move the star" loool :) this dude is super funny
I mean any civilization advanced enough to make a Dyson swarm could make a shkadov thruster, so about equally crazy rather than more so.
@@jasondolph2785 yeah but it still sounds sooo funny. It's like.. you don't say that normally about somebody. That they might be trying to move a star. Idk.. I think it's funny
i'd think aliens capable of advanced enough engineering to build a dyson sphere would've already met their energy needs.
Engineering challenge and fully saturating their energy needs I guess?
Vogons resistance is futile
Depends what they need that energy for I guess. I think any intergalactic space-faring civilization would benefit massively from harvesting their star's energy, I believe that's somewhere on the Kardashev scale right. But who knows, if they've had some major physics breakthrough that we're yet to achieve, they might have found an "easier" way to get the energy they need without resorting to a dyson sphere/swarm. Fascinating topic.
It also depends on what you mean by "capable of". Technically humanity is capable of building a Dyson swarm right now. They are just objects in space with solar panels to collect energy.....we have those now. It may take a while to build 100 quadrillion of them, sure, but we could do it without discovering one new piece of technology if you are patient enough.
Hard to quantify the energy needs of a civilization capable of building a Dyson swarm. I feel like what we think their needs are and what would think their needs are would differ wildly.
The amount of ‘material’ needed to build such structures would be absolutely astronomical! Much more than what a planet would have. So if built, it would be done by a spare faring species capable of collecting, mining, and transporting the required material. However, if a star system contained a natural belt of asteroid material that could be converted into a Dyson structure, then it may be feasible. Just a thought.
For more info on Dyson swarms and other megastructures, the channel SFIA has the 'megastructure compendium'. It's a suprisingly grounded channel considering the matters discussed.

If it is dust, use a vacuum cleaner.
@@camoTiaras i would but I don’t have an extension cord long enough
@@MichaelBrown-me3bh Just plug it into the nearest Dyson sphere...
@@camoTiaras I’ll still need several dozen, and maybe a junction box or tw.. oh wait.. I’ll just use my battery operated vacuum with Bluetooth connectivity, problem solved
I’m impressed that Anton has attributed the correct originator of Dyson sphere and not to a little old lady from Moscow!
If they can build a Dyson sphere, they would have also developed devices that harness free energy which would have then nullified the creation of Dyson sphere.
It really only makes sense that a Dyson Sphere would be built around a red dwarf. I hope the search is on for exoplanets around these stars as well.
It only makes sense to build a Dyson sphere if there is available matter in the system, no matter what the star type is...
John Michael Godier did a video on the same study. It mentions one is a red dwarf. Also The Angry Astronaut did one as well.
I just hope the dwarves are okay
K2-18b ❤
My vacuum cleaner has joined the chat…
Well... in a solar system "like" ours there's definitely enough metal and materials to make such a thing. You can use spectra to find out how much metal a star system has.
So maybe when we can get REALLY good at THAT maybe we could narrow down the systems that MAY have something like a Dyson sphere.
So cool. I would just LOVE to see something THAT BIG.
Man... so big.
Heisenberg said the the universe is not only stranger than we imagine, it is stranger than we can imagine. Seeing something strange in the Cosmos does not necessarily mean aliens did it. Just because Dyson imagined it, that does not mean it would be practical or even necessary for an advanced civilization to build.
Someone, an engineer, did a calculation in the eighties that kind of proved the idea implausible, since the amount of material that would be required was either not able to be moved, because of the energy requirements, or just not available in a given assumption of a solar system's available planetary mass. Even if those issues could be resolved, any such object would most likely not be able to be observed from our location. The argument was compelling, for what it's worth. (I couldn't track down the original, but it was related to an argument about Niven's series).
Nano replication tech defeats the scaling & energy problems...
This is correct - There are many implausibilities of Dyson Spheres from engineering perspectives. Also, advanced civilizations will get energy easily and cheaply from nuclear power, fission or fusion.
"...any such object would most likely not be able to be observed from our location." "...in the eighties..."
Back then, we had no infrared telescopes like JWST. Infrared is exactly the light you need to look for one of these. Hell, IRAS was launched during the eighties and the engineer may not have been aware of the project.
Regardless, waste heat from these things is how you look for them even if the builders are dead and not emitting signals.
Which is why they would build swarms instead
Straight energy into matter conversion and you can capture all the energy needed to manufacture the sphere
How creepy would it be if like half of all stars had Dyson spheres around them?
Creepy? Not at all. Very interesting an exciting though.
@@GerlaffyYou are mistaken. More spheres than alien civilizations means some unseen entity is acquiring a lot of real estate.
@@christopherbrice5473 who said there would be more spheres than alien civilisations? That's a whole other thing
@@christopherbrice5473 Some unseen entity? You mean like an alien? LOL. It doesn't matter if it is unseen if it is making Dyson spheres. Proof of alien intelligence would be the Dyson spheres themselves.
The really creepy thing would be if dark matter is the result of very advanced civilizations hiding their stars and planets from dark forest predators.
For folks interested in Dyson Spheres in science fiction, Bob Shaw's Orbitsville and Stephen Baxter's The Time Ships are the novels for you.
The concept of a Dyson sphere is incredibly fascinating. If a civilization exists that could build such a structure and inhabit it the thought of such a thing is mind-boggling. For example, what would be the surface area of the inside of a full Dyson sphere where it encloses a G type star in the Goldilocks zone? Would a full Dyson sphere re-radiate energy if it is collecting all of the energy from its host star? I would think it would appear as a black hole in space especially if the material is capable of capturing all of the energy striking it and not being re-radiated. It brings up all manner of how one would protect the inner surface from solar flares and the solar wind. Lots of things to think about. The sheer volume of material required to build any structure around a G class star would be beyond comprehension - where would you get that much material and how would you get it into place? A sphere roughly 196 million miles in diameter (since we are roughly 98 million miles from the sun would be a gravity structure in and of itself. What would drive a civilization to build such a structure in the first place? Just a small smattering of the things I've thought about over the years since finding out about such theoretical structures. The big question I have is how do you keep the star in the center? For some small calculations: An enclosed Dyson sphere would occupy a surface area on the outside of 115,811,671,581,934,138 square miles. The volume of such a sphere would be 3.705973497126268125092122e+24 cubic miles with a star in the middle (can you imagine even traveling from one part of the structure to another??? At the speed of light it takes 8 minutes to from our sun to the earth and let's say you wanted to travel from your location to the opposite side - now you are on the arc of the interior surface of the sphere if you don't travel along the diameter - if you travel along the diameter how far do you have to be away from the captured star? Assuming the shell might be 100 or even a 1000 miles thick the inside area is still going to be astronomical. How many habitable planets could one put on the surface area of such a structure? The thought is beyond sci fi but of course any civilization that could build such a structure would have solved all of the problems I have conjured up and then some. Thanks for a neat video and making me think about things way beyond my meager capacity.
I have been always skeptical about the concept of a Dyson sphere, because I can't see any advantage over nuclear energy sources, that can produce energy in an arbitrary manner. A sufficiently developed spacefaring civilisation can use e.g. aneutronic p-B-Fusion to build efficient and scalable electrical energy sources. Either in stationary or mobile applications. As already the concept of photovoltaic satellites show, transmitting electrical energy over vast distances is quite expensive - and not very effective.Nuclear energy is still the most densest form of energy, because it is condensed as mass and released according to Albert Einstein's famous equation E=m·c².
Dyson Swarms a sphere would be almost undetectable. You need the open spaces so you see the excess infrared light.
he said that tho
Nope.
The open spaces let you see the star.
The structure itself must heat up and release waste heat equal to all the sunlight it blocks in gamma through to infrared wavelengths.
That's why they are looking for the spike in infrared light. (If they somehow kept all the infrared, they'd boil themselves to death.)
@@archapmangcmg exactly why I said not a sphere.
Not really a sphere itself would absorb the heat, and unless you can break the laws of physics that heats is going to radiate outwards..But a sphere can never be stable around any star the forces applied to any type of material due to gravital interaction would far exceed any material we can think of including carbon tubes by factors.. So almost again you need to be able to break physics as we know it. I really would get nightmares having such a society living near us.
@@randar1969 The shell would have the insane strength requirements. The swarm would not. Statites and lagites might be used for much of the swarm.
The issue I have with the idea of a Dyson sphere or swarm is simply the sheer amount of consistent material that would be required to construct it. Even if you took all the material on Earth and stretched it out, it would be a needle in a haystack compared to what would be required to build a full swarm, not even a sphere. You could probably strip an entire solar system worth of material and not even come close to having what you need in raw materials. Also, building such structures in close proximity to a star would cause pressure and resonance issues with the star itself, likely stressing the components to the point of failure. A sphere itself would likely be impossible to build without it eventually cracking open like an egg from the buildup of the release of solar wind and particles alone. It's an interesting idea, but if aliens are smart enough to come up with faster than light travel, I'm sure they have come up with some source of power generation that wouldn't require something so primitive in comparison, not to mention would take far more energy overhead to create than you'd get out of it to start with, so what's even the point? Just a dumb idea all around from my perspective.
More likely natural rings at odd angles of inclination, possibly also with short lived precession.
The obvious problem with a Dyson sphere is where on earth do you get all the material to build it with? You might as well build planets.
Keep going... you use planets
Planets are pretty inefficient collectors of solar radiation. If you have the ability to build planets, a dyson swarm is much more efficient.
You use self-replicating von Neumann probes utilising abroad belts & planets.
There's a Kurzgesagt video for that, highly recommend.
Meteors, asteroids. Why build a planet if you can't support it's energy needs.
Nothing is as exciting as astronomy & cosmology. Except consciousness research. Of course all the sciences are ultimately inherently interrelated, the boundaries being artificial, to allow us to think & speak about them. But these three are special.
Oh you nearly had me all riled up Anton with your James Dyson prank!
On some astronomy video recently I saw a "Mike Dyson" joke. Something like "every planetary system has a plan until a solar flare punches it in the mouth."
