Dyson Spheres? Two Studies Find Dozens of Stars With Bizarre Emissions 

If it looks like a duck, quacks like a duck is probably just some type of interference cloud we're not familiar with

dust around star, sounds like a job for a certain vacuum cleaner

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.

The amount of materials required to build such a structure would in itself seem to present an insurmountable challenge.

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

That Dyson guy can build anything..

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.

"Misstuh Datuh, could this be a Dyson Sphere?" "It fits the known parameters Captain."

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!

The reason for this video is Anton wanted to use all the awesome art floating around for Dyson spheres.

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.

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

I just want to take a moment to remind Anton that he, too, is a wonderful person. 💜

If a number of such stars were found in close proximity to each other, that could be more compelling.

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!

How very interesting! Your channel just keeps getting better each time. Bravo! 😊

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.

"It's never aliens" Aliens: "Are we a joke to you"

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.

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.

That's as click-bait a title as I've ever seen Anton use! I'm totally in.

Olaf Stapledon was a pioneering philosopher and science fiction standout. Amazing freedom of mind.

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.

These always seem to turn into some kind of "dust".

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.

Dyson: "We have the most powerful vacuum cleaners ever!" Black Hole: "Hold my beer!"

I'm glad you mentioned Star Maker. Dyson, if I remember correctly, gave the book credit for inspiring him.

What if every Brown Dwarf star was a main sequence star with a Dyson Swarm?

I think the universe is so vast that everything we can imagine, exists and much more that we haven't even imagined yet.

Absolutely fascinating stuff, you are such a treat to listen to!

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.

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. ;)

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.

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.

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!

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……😊

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.

A fascinating concept that started out as science-fiction, but now we realize that it is definitely a possibility. Good video!

I appreciate your passion for this topic my friend.

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 😂

Of course they could be Ringworkds - hat tip to Larry Niven

well, that's why YT is proposing me these Dyson vacuum ads! thanks Anton 😂

Another fantastic video. Well done!

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?

I read through it. They put in a LOT of work to narrow these down. Well done

I remember when Anton was just a small dwarf in the corner of the screen.

Just ordered another t-shirt from you. Love your vids. You're a wonderful content provider... person.

I would hate to meet the kind of civilization capable of building a Dyson sphere....

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!

I love his theory... it’s one of my favorite Star Trek episodes. Thanks for the academic perspective.

I’ve been watching this guy since I was 12. I’m now 22 Thank you for growing up with me Anton

lol, Anton. The shkadov thruster bit was brilliant. I laughed out loud.

Lol the Dyson joke was great 😂

Ring World! Larry Nivan.

Exciting information indeed, thanks 👍😊

I was about to skip "What is it though?" thinking that I knew. I held off when you mentioned the origin of the idea, glad I did.

This one was kind of fun to think about! 😊 I guess because I'm into Star Trek!

Thanks!

Oh you nearly had me all riled up Anton with your James Dyson prank!

I just love your comedy Anton! 😂❤

Dust around the star. Again.

Any star that doesn't neatly fit our preconceived notion of stars must be a Dyson sphere.

Thank you anton for great video

You really cracked me up with the James Dyson joke. Brilliant. Now I'm thinking, Dyson Sphere or Dyson Ball? 😂

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.

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."

Your channel blew up. Good on you

There are LOOOAADS of other possible explanations that should be preferred over something like the Dyson sphere fairy tale.

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.

My "Dyson," vacuum cleaner has a large sphere on it. It's made out of some type of plastic.

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?" 🤣

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

"for all we know, somebody might be trying to move the star" loool :) this dude is super funny

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.

I can totally imagine a star covered and surrounded in Dyson carpets cleaners 😂

properbly never anyone will make a dyson sphere. it will take to much resources from their planet to create. i love your videos

Remember guys, it's never aliens

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

"It will probably take months to see what's up"... I like your optimism.. I'd rather say centuries 😋 Thanks for the nice video, as always

Thanks Anton

Oh it must be a Dyson sphere.. not dust 😂

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.

thank you liked and shared very interesting

both super exiting and terrifying haha if they are dysons lets hope our neighbors are friendly as they are overhwelmingly advanced and productive. esp if its actual spheres and not swarms they found ways to connect matters in ways that goes FAR beyond regular molecular bonding and most likely even the strong force. which also means there is still SO much to learn

i'd think aliens capable of advanced enough engineering to build a dyson sphere would've already met their energy needs.

My vacuum cleaner has joined the chat…

The Dyson is only end game move for the non starfaring. Relocating to a Dyson like structure is only hope a species has of surviving being left with a white dwarf. That's where I'd look for a Dyson. Around dying stars. As a life raft for an interplanetary species that ran out of time.

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.

They should use the satellites to look for intelligence in our politicians.

James Dyson has harnessed the power of a billion pet owners, cleaning their floors. 😂

Aliens might need to break the whole planet to build that kind of a big structure.

Any civilization with the resources, infrastructure, engineering, and tech to build a Dyson sphere would not need a Dyson sphere.

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).

Dyson Swarms a sphere would be almost undetectable. You need the open spaces so you see the excess infrared light.

"Star light, star bright. The first star I see tonight. I wish I may I wish I might. See a Dyson sphere shining bright"

More likely natural rings at odd angles of inclination, possibly also with short lived precession.

How creepy would it be if like half of all stars had Dyson spheres around them?

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.

Thank you for keeping an open mind, and eye for these structures. May I recommend Larry Nivens " Ringworld Series" for those interested? You are wonderful!

I wish there was a video about this topic that included a galactic map showing the locations of these potential Dyson swarms relative to each other and to our solar system. It would be interesting to know if they were clustered near to each other and how far away they are.
