Is this how aliens would rule the universe?
The word aliens might feel very unscientific but the idea that we aren't alone in this universe is a well believed theory within the scientific world. With 6 billion Earth-like planets within the milky way is it so hard to believe there could be extra-terrestrial life out there. Dr Josie Peters explains some more.

They're already here.
They don’t like the Mets either
That will be both terrifying and exciting if we discovered an advanced civilization. If they are more advanced then us, then they are already aware of our existence.
@Dark Knight fair enough. it’s just an if. Not say we will. I know we have a long way to go.
You can tell if they are too advance if they Dont belive in Fairytale being like Humans! Bcoz of this stupid Hoax in Human History become one of the factor thats why Progress slowing down on our Civilization
Recommend searching up Life Beyond 3 by Melody sheep^^ pure masterpiece
That doesn’t necessarily follow. Just because they’re more advanced doesn’t mean they would already be aware of us.
More likely, perhaps, but not a certainty.
@Dark Knight ok but if they look at Earth and see just dinosaurs (life on other planet) they would come here to investigate.
If they are advanced enough there's a chance they would be the ones finding us.
A super-advanced civilization might very well have technology so well integrated that we might not recognize it as technology. Also, black hole-farming might be a much more feasible way to get huge amounts of energy from a cosmic object than a humungous dyson sphere built around a star.
And I highly doubt they'd be using solar panels LMAO
@@Awesomenesses Cant, solar panels are too intricate for something like a Dyson sphere. More likely it would be small pieces of reflective material that focuses the energy to a centralized collection location.
Yep, and that technology might be a self-proliferating and self-reprogramming carrier of information....perhaps in the form of what we know as genes??
@@diracsea4590 - How in the hell could you possibly predict what would be "too intricate" for a Kardashev Type 2 civilization? My god but the hubris of some people is simply amazing.
@@sam21462
The laws of physics dont change when you go from Type 0 to Type 1 or Type 2, and this is a Type 1 going into a Type 2; and humans are close enough to a Type 1 to know what they could use to get to a Type 2.
Solar panels are manufactured a very specific way and from very specific materials (we know this bc we manufacture them now on this planet) and they are also not very robust and need a lot of maintenance to stay in working order. And when I said too intricate I meant how they are made and how they work/function; panels needed for a Dyson swarm need to be as independent as possible with as little intervention as possible; so simpler is better it will also cut down on the cost of manufacturing (both monetary and resources needed). If you want to guess at a magical unknown kind of solar panel thats fine but I am working off what we know right now and extrapolating out a pleasurable method of creating one.
And if you want to talk about hubris your comment alone is it; you have no concept of how solar panels are made or what it takes to keep them going and in good use; and is why nuclear power is the better option for us right now. I have an engineering and physics degree and find space fascinating. Science builds off itself so we come up with ideas, plans, and theories; then change them as we get new information. That new info may not come in our life times so its up to the next generation to build off those ideas and make them better and scrap the ones that dont work.
If I was to build a swarm I would build the needed items (in this case reflectors about 1km in size) on Mercury bc of the resources there (very metal rich) and the low gravity would make it easier to get them into space and position. If I built the items at 1km Id need 30^15 to go around the sun; to make that many as light as possible youd need 100^18 tons of material, and thats for my mirror idea (anything more complex and the weight to get into space and resources need to produce would go up). Mirrors that reflects to a collecting station like we do now on Earth for solar farms is the best method.
At the end of the day any Type 1 will not have discovered a new element that we havent found yet that can change how the laws of physics work when it comes to solar collection; all they would have gotten is how to put those elements together differently, which is possible they could find a different method but again I am working off what we know for sure would work in the here and now.
But please explain how your magical solar panels work.
Both outcomes are terrifying: either we're alone or we're not alone in this vast universe.
We’re probably what other civilizations fear
I don't know, but somehow I think a civilization that has the capability to build a Dyson Sphere won't need to do so, as they'll have more advanced technologies to get power (than the caveman tech of harnessing power from a star).
I think you're right. They might have the tech to smash matter with anti-matter to yield 100% energy output rather than undertaking this stellar task of building cosmic structure which would eventually fail after the star dies out
Totally agree. Some pretty low level thinking going on here... Assumption of all energy is derived from the power of the sun. When there are many forms of energy...
It also assumes that the alien would harness "power" from a nearby star. There could be other ways that we just haven't even figured out beyond our understanding.
Yea that’s so 90s 🤓😂FOH
@@jakedovey1586 and we humans think we are so intelligent lol
Whoever doesn’t believe there’s other life besides us in this universe is crazy.
I believed there must be life out there but recently I feel we might be the only one. The thing is what if the odds for life are so staggeringly low, even with all chemical ingredients needed for it available? We still have no idea how life started, what made it replicate and function. If the odds are unimaginably low, we could easily be the only living thing in the entire universe. I think the odds for life are so low in fact that it can happen only once per universe.
@@Zhiivago you still have the other universes lol
@@yannipaulos1071 there is only one universe...
@@deltadragking6623 and how would you know brother
@@Zhiivagotheres literally infinite galaxies and you think we’re alone in the universe lmao
"Humans are at their most endearing when they attempt to understand subjects beyond their reasoning skills." -Anon
The odds are that there is something alive out there. We just don’t know what. And the vast void of space will prevent us from seeing it anytime soon.
Exactly there’s no statistical way there isn’t something out there
I don't think it's a matter of if there is life out there it's only a matter of when we're going to encounter it. Would it be a non intelligent lifeform then we're safe. If it's something far more advanced than us things get a bit scary and do you really want to get their attention in the first place at that point. I'd say that it's almost safe to assume that an intelligent creature that has been around for millions or years or longer would have evolved to NOT be aggressive(unlike us humans). We're very primitive in how we deal with each other and other lifeforms on our planet. We're also very destructive and "young". Worst case would be encountering a lifeform with similar technology advances like ourselves and just as young. They could very well be hostile.
@@huldu That would be AWSOME watching you run from aliens 👽
I like to think of how two species of intelligent beings different from so many light years had the same idea to extract energy from the sun
Gotta ask yourself the real question. Does other intelligent alien life also have a form of internet where automated messages containing links to pornography get sent around?
@@rithrius5384 😂
Let's be grateful and feel blessed that we exists in this very rare phenomenon called life✌️💫✨
hm life is common and no one will remember nor will they ever know about your existance and u have no idea what happens after your existance so i wouldnt say we should feel blessed cuz who knows after death suffering could come or even worse you suffer while lifing which most ppl do anyway
@@popomelon7878 out of billions of sperms in the race only u as a sperm got chance to be a human being, i think that's pretty rare right brother ? 🙂
i love how sincere they are with the results of their researches and not try to cover up when something does not happen as expected.
Like cameras turning off mysteriously when entering the cydonia region of mars
The idea of harnessing the natural energy is vital. Amazing series.
wouldnt a structure of that mass generate its own gravitational field, disturbing the star and/or itself? how do you keep it above the stars surface?
(From Wikipedia) The Sun accounts for about 99.86% of the total mass of the Solar System, so the mass of the Dyson Sphere won't affect it, or at least not more than the planets it is built from.
As for keeping it above the star, I can imagine the thing easy for a ring shape structure (not a single solid ring, more of a constellation of separate elements more or less connected, revolving around the star at a safe distance ), but for a sphere, it seems complicated => The poles of a Dyson Sphere don't rotate in relation to the star, so... what happen then ? Do they fall towards it ?
Just think of a sphere as a ring in every direction. For every point A in the sphere there would be a polar opposite point B experiencing the exact opposite gravitational pull from the sun. They would all cancel themselves out because the sphere is connected.
might add to the wobble of the barycenter, but not much
@@jkonkl3 the sun orbits about a common axis as the rest of the solar system called the barycenter, it's not equal.
@@SGUnity Go simpler, mass isnt being added (if other planets in the solar system are being harvested for material) so where would more gravity come from?
Imagine if that disintegrated "moon" was actually a derelict Dyson type structure! Would there be any way of detecting that? I'd love to see the scientists in the lab one day "That's no moon!"
The more you look into the sequence of events that led to multicellular organisms and intelligent life on Earth, it becomes apparent how ridiculously rare we really are. On a universal scale, it’s fair to say we are not alone. But on a galactic scale, we may very well be alone. Either way, it’s exciting that we are doing are best to find out.
I'm sure there are thousand of complex life on the galaxy
I dunno, we basically just got started looking. we're super new to tech on a astronomical scale. It's like our first day at work.
Then there is the factor of time. "We" (whatever that actually means) existed not even for a blip on the cosmic time scale. Which makes meeting any kind of life form at a similar stage as us (ignore for a moment that we don't even know how to leave earth's orbit) even less likely.
Dyson sphere seems like an extremely fantastical idea.
Not only the amount of matter and energy needed to create it, but it would most likely impede the effect of the heliosphere so that life as we know it would be exposed to unmitigated cosmic radiation and make its existence impossible.
'it’s fair to say we are not alone' - BS assumption
@@tomsmith4542 I literally said it’s “fair” to say. Meaning plausibly or reasonably likely. I never stated anything with certainty. You apparently do not understand the word “assumption”, which implies certainty. It’s very much my own point of view. Feel free to have your own.
The evening air was cool and crisp that night. It was the first full week of Autumn and we decided to go camping. It was to unwind and relax from the hustle and bustle of our daily lives and the kids always liked all the play time out in the woods. They always got excited when they heard us speaking about it at the dinner table. The place we would go wasn't that far it was in our local sector. Although this time we were going to go somewhere different, it was still time with the family. So I didn't mind. A few day's before we all started getting ready. We loaded up everything we needed for our trip checked with the neighbors to see if they wouldn't mind watching our place for us while we were gone, collecting the mail and stuff. We had been doing this for each other for as long as I can remember. The next morning we were on the road before dawn. Loaded up and full of coffee. This was going to be great. As we had always done so we discussed where it was we wanted to go that week and how easy it would be to get from here to there without much of a hiccup along the way. We didn't do that this time, and as we climb into the captain's chairs of our vehicle, my wife looked at me nervously and said "Honey, Where are we headed to? She said in a whimsical way made me chuckle abit. As we strapped in I said "A place the locals call Earth"
Our people had noticed it's place in the known configuration of systems long ago. The sphere had shown early promise to our planetary researchers. Only because of some little one was out in his back yard and made the discovery in the first place. But that was long ago. It's sad though because of the history of that sphere and the inhabitants of that world seemed to have all but disappeared before we could make contact. Either they met with some terrible demise or they themselves moved along the star's. To other sectors and systems that which they discovered along their own journey. I think they faded out because some of the earlier sojourn there came back with some vid-link that showed some unpleasant things. Great ruins long lost to time and whether. "But, don't worry Honey" I said " we won't be going to any of those sites this time."
It’s a bit disappointing to see them attributing the Sphere design to Freeman Dyson. Actually disliked that people kept giving him credit for it. His idea was the Dyson Swarm, which was mentioned in the video thankfully.
Never been a fan of this theoretical alien gadget. All it would take is one serious burp (as in a major coronal mass ejection - which happens pretty often) from the host star to totally ravage a structure that will take eons or longer to even build. Truly intelligent life forms would find other more efficient and reliable ways to get the energy they need without destroying entire solar systems to build a solar bird cage.
Yes but red dwarf stars, while they indeed do kick out a lot of radiation, they typically don't throw off a lot of material, and nowhere near as energetically as a main sequence star like ours.
@@jedaaa But the catch with red dwarfs is that the energy and investment to build a Dyson sphere around them would make even less sense since they are way less energetic than main sequence stars like ours yet the monumental build would be almost as challenging. They are a lot more common in the universe too and not even a trace yet.
@@letsgobrandon987 sure but I don't think you'd actually need to ever harvest the entire energy output of a main sequence star or even a red dwarf, I think harvesting something like 15% of a red dwarf would still give you more energy each month than the earth has received from the sun in a million years. It's also worth noting that most solar systems are binary, so you could live happily around your main sequence stars planets while using a nearby red dwarf as your energy collection and not have to cannibalise the planets and moons of your own system
@@letsgobrandon987 let's go Biden!
@@Andysaid420 Yeah Let’s go biden - to war with Russia
The term "Dyson Swarm" is more realistic and far easier to build than "Dyson Sphere".
It would just be adding more orbital solar collectors over time.
Umm, a "ripped apart moon" would have fragments and dust which give off infra red as they heated up...this has yet to be detected for Tabby's Star.
This is what I was thinking too about a Dyson swarm over a sphere; too costly for a full sphere.
I was thinking a planet being ripped apart (asteroid belt) or a comet swarm over a moon.
What if an "advanced" civilization didn't require energy at all? Why assume that any life form would consume and capitalize the way we have? What if they found a way to not squander what they have? If you lived in a place where you had plenty, would you need to look for more? What if greed and ambition are human traits and human traits alone?
Always with the theories.
I, for one, welcome our alien overlords.
(lol)
Since I am not native to english it would help me tremendously to grasp what's being said if the music volume was turned down when Dr. Peters talks. Thank you!
I'm glad to hear that some scientists still admit that "they MAY not be out there"....rare these days. :-)
The guy in the bookstore has too much time on his hands 😂😂💀
Every since I first learned of the enormous number of galaxies that exist I have always felt that we are not alone, but, I also think it incredible that there appears to be no one in the local vicinity and that after decades of probing space with telescopes of all manner, we have yet to detect any signatures attributed to any type of civilization.
2:08 A scale which makes no practical sense. WHATSOEVER!
_"A Kardashev Type I civilisation is a civilisation that's capable of harnessing _*_ALL_*_ of the energy that falls on their planet."_
_"In order to achieve Kardashev Type II,
a civilisation would have to be able to harness 100% of the energy of its closest star."_
However, no civilisation can ever harness *ALL* of the energy that falls on their planet, as this would destroy the ecosystem. In fact, it gets harder and harder to utilize a higher and higher percentage of that energy. Since *ALL* of the surface would be needed to harvest that energy.
Nevertheless, as the civilisation progresses, it gets easier and easier to harvest energy outside of their home planet. As we currently already started (mostly for space probes and rovers ... and yes, we are still a type 0, by any measurement). So, even before a civilasation turns into a Kardashev Type I it is way on its way to a type 2 and probably "works" on type 3 before it even reaches close to type 1 according to the scale.
The fix is easy, though. Rewrite the definition to:
_"A Kardashev Type I civilisation is a civilisation that's capable of harnessing _*_the equivalent of_*_ all of the energy that falls on their planet."_
Oh, the scale has similar problems with type 2. Same fix, though.
A dyson structure, yes. It could also come in handy to save fuel for slingshotting probes and satellites that would be close enough to melt or destroy them otherwise, making further exploration more efficient. I agree.
Plot twist: we are the aliens for outer space other life forms.
The thing to remember here, despite the age of the universe and the size of it, the number of potential worlds, etc is that it is a fundamental and inescapable fact that someone has to be first.
Someone has to be the first life to exist, the first to become technologically advanced. So it is not too much of a stretch to believe that despite this all _we_ are the first. Not just as an advanced civilization, but the first life to arise anywhere in the universe. The arguments about the age of the universe are one thing, but remember that life didn't arise on Earth until 3.5 billion years ago and the universe is over 13 billion. There is nothing to say that life must arise early or at this particular point in time.
To say that the universe can be stranger than we imagine, then why not imagine that in all this vastness, we are alone and possibly always will be. There is no steadfast rule to say life must have arisen elsewhere already and is prolific.
Or why we don't remember that we have barely searched anything in space and with universe expanding every single second and the limitation of technology that we and even other civilization might have has ensured that we never get in any kind of contact ever. The way universe is designed, to me it always looks like that the creator never wanted to allow any two intelligent species to communicate with each other
Earth is 4.5 billion years old and first life is estimated to have arisen only half a billion years after that...
@@siertje100 Yep, still 10 billion years after the formation of the universe though. But inevitably, we will never know if life arose anywhere, whether it's still around or gone, in those first 10 billion years. But the point I want to make is that there is always the possibility that none has and we are the first, alone, and possibly always will be, rather than the certainty many have that life is abundant.
@@edkrzywdzinski9121 I'm not certain that "first" really has any relevance, like yeh one has to come first but it does not mean that even if we are the first, that there aren't any others out there. Given the shear size of the universe it is not unthinkable that even if we were the first, the second could have reached sentience a couple of days after. Basically I am saying that if enough time has passed for it to happen, then enough time has already passed for it to happen elsewhere.
And just like it is an inescapable fact that there needs to be a first, due to the relatively broad range of environments that life is able to survive in and so how common it likely is, it would be highly irrational for any one species to assume they were the first.
@@MrMyers758 I realise now I should have phrased it as "first" and added "and so far only." That is what I was getting at, that we might be the first life to arise and other life may or may not follow.
But I must disagree with you on this one, it would not be irrational to assume that, because it is a basic truth, perhaps more relevant than assuming there is life elsewhere. If the evidence so far suggests there is no life (whether it can be found remotely or not) that assumption is valid until new evidence is found to the contrary.
the fx guy had some work with saber
They should have played a slow and creepy "Twinkle twinkle little star..." at the intro.
My bet is that all civs eventually reach a stage where they put their bodies in a pod and live the perfect life inside a simulation, So the reason we can't find aliens is because they are not out building and exploring but laying instead hooked up to computers
I really don’t like the idea of contacting a civilization that is more advanced than us
The fact that anyone could think we are the only intelligent life in the universe is the height of arrogance. We aren’t that special people!
Why the obsession with harvesting solar energy. Surely an advanced civilisation would find easier ways to generate energy (or power)?
Antimatter would be the goal, but if you look into what it takes to produce just a fraction of a gram of the stuff .......
Where to stream this in India @bbc
Interesting....
3:08 Not sure if a Dyson Sphere or Swarm is feasible or even possible. ... or if it is another Hyperloop ...
I've always thought Dyson spheres are some kind of outdated sci-fi, when solar panels were too sci-fi
What we have to remember is that many of the stars we see are tens of thousands to billions of light years away, meaning that we see them as they were thousands to millions of years in the past. Where am I going with this? Well, just because we don’t see or perceive intelligent life on an earth like planet 600 million light years away, doesn’t mean intelligent life is not currently there and the same goes if we ever find a sign of intelligent life. If we spot it on a planet 100 thousand light years away, we have to remember that they might have went extinct already.
We have pictures and videos 🤫HAPPY NEW YEAR
Enjoyed the video but some part of the audio especially the parts when the scientist-host is speaking is not as loud as other parts.
Interessante ...Este tema é apaixonante! A Terra envia continuamente para o espaço emissões de rádio ...talvez outros planetas façam o mesmo!? Em tantos anos de escuta ...nada se descobriu que se deva, sem sombra de dúvida, a um sinal acidental proveniente de outro mundo embora se tenham recebidos sinais inexplicáveis ...mas se enviarmos uma mensagem teremos que contar os anos luz a que chega ao destino e os mesmos anos a recepcionar?!! E muito tempo...e difícil, no entanto ficamos na dúvida?
Radio waves begin to break down after a couple of decades, and even so I doubt advanced alien civilizations would still have receivers capable of reading radio waves 😂
Seems like it would be easier to perfect Fusion versa using all those materials and logistics.
Dude after watching this, i really like to play stellaris all again. Gonna kick those alien butt
My first guess would've been broken fragments of a massive planet blocking the light for a long time in an irregular shape, covering a large surface area
What if we humans are the one of many young civilizations who thought of such Dyson energy harvester while older civilizations never thought of such thing or they simply retired all their dyson structures and moved to a different way to get energy?
has anyone else than me ever tought of the fact that life may be common, but we could be the advanced ones instead, and the rest are just figuring out how sticks and stones can serve as tools
Really think an extremely advanced alien civilization is going to be using solar panels?? HA!!! They can harness energy from the atoms in space itself
Background soundtrack?
You should watch melodysheep's series on these. It's called Life Beyond and I highly recommend. Especially Life Beyond 3 which explains the Kardashev scale
It would seem that the occurrence of multicellular and intelligent life in the universe is fairly rare--seemingly rare enough that contacting or even detecting each other is significantly difficult. You'd think that the rarity of life in the universe would lead us to value what we have even greater, yet we don't. It makes the tragedy of human-inflicted extinctions (of so many animal and plant species) so much more impactful. Perhaps it would be fitting if we caused our own extinction--since we value life so little.
Shouldn't the first question be if there's an astroid belt? What are some other videos on this?
but I mean the universe is so big so I think its true
It only took humanity 20000 years to get this advance... And the universe is billions of years old. Advance civilizations may come and go. So are they gone or simply too advance to care about our existence
أَلَمْ تَرَ إِلَى رَبِّكَ كَيْفَ مَدَّ الظِّلَّ وَلَوْ شَاءَ لَجَعَلَهُ سَاكِنًا ثُمَّ جَعَلْنَا الشَّمْسَ عَلَيْهِ دَلِيلًا
this make sense for me now! thanks 🥀♥️
Bootes void was an example of it
6:14 Or it's a ring.
Nice time
That's just the very same moment it came out about "Life Beyond III" on melodysheep channel. What a coincidence.
A Dyson Sphere doesn't make much sense to me. Apart from the astronomical amount of material needed to build one, they should take into consideration that advanced civilizations might not need that much energy, since they would certainly be much more fuel efficient.
As a Type 0, not only are we able to suggest what more advanced types would be, but we also beleive we may have discovered something from a Type 2 society and it happens to be almost exactly what we theorized it would be? How crazy is that? Really crazy. And just a little bit arrogant.
Just a correction to the estimated two trillion galaxies: In 2021, data from NASA's New Horizons space probe updated this previous estimate to roughly 200 billion galaxies to the 2016 estimate of two trillion+ galaxies in the observable universe. Overall, the video highlights important questions for scientists of our generation to consider.
*Thinks its aliens harvesting a star* turns out to be a planet that collided with another planet and you're looking at a system wide grave yard of rock. But aliens sounds way cooler
building something like a gyro disk around a black hole is the way to go.
Alien: "these earthlings are always trying to find us while we do our best to avoid them."
so we're just going to completely ignore artificial fusion entirely or matter / anti-matter reactions?
A Type 3 civ wouldn’t think much mor of humans as they swallow our star, than a six year old would running through their yard and kicking over an ants nest. A Type 2 would maybe look at us like smart rodents in a cage. Here’s hoping that an advanced civ doesn’t find anything even boring about earth and just marks us down as ‘mostly harmless’.
I think the alien civilization at that star system is small enough to shroud their existence with star dusts.
Wow. And if the sun is covered? We gone live with electric light?
LIFE is as COMMON in the UNIVERSE like the DUST on the earth & life's ultimate GOAL for the EVOLUTION will always lead to the INTELLIGENCE.
Spoilers:
This is just GTA 5678, alien civilization will include on GTA 5679.
When we think about utilizing the sun's energy used to grow crops that feed animals that we eat, as well as the plants that we eat. Is that calculated in the kardeshev scale?
We must use all energy , we’re 0.73 on the kardeshev scale.
Prometheus crew has entered the chat
I wonder if they are also doing their best to find us.
One of my biggest pet peeves is when channels say so and so many “billions of earth like planets”. To justify possible life elsewhere.
1st-“ earth like”is misleading. That term means either nothing technically speaking or the most common agreed meaning is simply that there is a planet orbiting a star in the “Goldilocks” zone.
But we are finding that most are gas giants: not terrestrial.
4:25 I may quote (freely) here. _"It's never aliens, unless they come around and starting shaking hands"_ and _"Slime is common, but a beautiful woman is rare"_ (means most life will be slime)
Indeed it would be a pretty strange universe in which life only arose once...but then again, "what if" we are the first? Hmmm...
What if finding aliens we found humans in different parts of the universe and yet we think their aliens
"OOPS! All Humans." if the universe were a cheeky kids cereal.
Making contact with Aliens will ultimately end humanity 😂.
host mentions aliens (shot of a misty forest)

BBC if you need a new editor i could really use the work right now
I was thinking already to design a technology to use the thermal energy of Venus to sustain a exoplanet ring around 🤭
Was already determined to be dust.
A Dyson sphere only costs about 55,000 alloys and 300 influence to make. Takes awhile but we can do it.
If you build a Dyson sphere around a star then have to transmit power to a home planet , why not collect the energy on the planet as the star already transports energy via radiation.
Also blocking energy at its source would surely cause negative issues on the stars solar system.
I thought that Dyson made home and commercial appliances?They have gone up in the world,as they say.
why would any civilization build such a huge sphere if they could harvest energy easily from fusion reactors?
The star is the fusion reactor.
Fusion reactors are way primitive for advanced civilizations.
like a sun?
Isn’t all the planets in our galaxy the same age they would have to be millions of years ahead ?
Hope the alien who cleans those panels gets hazard pay. 😅
Our “space exploration” is the equivalent of you going from one side of your living room to the other and that may be exaggerating.
I thought Aliens Are Imaginary 🤔💭👽
Something not round in front of star ⭐
Is it something flat? Like earth 🌎
I like this video where a bunch of nobodies read us a wikipedia article unconvincingly.
Do you think that information would go public if it's one day confirmed?
If it's no threat.... Then they'd probably announce it
O Universo é misterioso
Could be giant irregular space rock. Our solar system is filled with asteroids...other star systems may also have such asteroid belt... Giant irregular space rock...
Imagine if Aliens are advanced Chickens. If so we’re in trouble.
If Aliens have to build Dyson sphere large enough to block good part of a star's light for energy, that implies nuclear fusion is either unfeasible or impossible, that would further imply travelling between stars and galaxies to be improbable or impossible, that would also imply that communicating meaningfully of our existences to each other would be next to nil, do we still call such civilization advanced?
That's a lot of conclusions to jump to. Building a dyson sphere would require resources from possibly multiple different solar systems, and you obviously wouldn't want to build it over your home star. To reasonably get those resources, you would have to be able to travel between star systems. Communication between different star systems quickly seems like a very difficult feat for us, but it may be much different for a civilization many times more advanced than us. And all of this doesn't mean that fusion isn't viable, it just means that the civilization has the capability to create a fusion reactor on a massive scale (by harnessing the power of a star).
the star is doing the fusion, so why bother with other methods at that point?
What if it is asteroid belt?
I think we are the first civilisation in the universe to figure out technology,,,
Tabby's star mega structure thing was debunked pretty quickly though. No clue why a video made eight years later would even try to use it as there sole example.
