Imagine how many species are asking themselves this question at this very moment in time and then you calculate the odds, considering you know the universe is a multi digit factor of times bigger than that. The enigma is preoccupying us more than acceptance that if every galaxy had an intelligent species by this time, we would not know of each other and still you’d have an Incomprehensive number for your answer
Wouldn't an anti matter engine be more efficient than building this giant monstrocity of a dyson sphere? I always thought the dyson sphere idea was a little silly. Surely any civilization advanced enough the build such a thing would have been smart enough to not have to, not to mention the audacity to suggest that we could even begin to imagine how they would power their society.
Swarm, not Sphere, like the video said. A Sphere is silly to me too, but not as silly as making power with anti-matter. We already float solar collectors around the sun, a Dyson Swarm is just a lot more of them. On the other hand, making anti-matter USES more energy than you can ever get back, unless we come up with a new magic-tech Star Trek antimatter-maker. As far as anyone knows, we would need a fairly good (at least .01% collector IIRC) Dyson Swarm to have enough power to make fuel for the anti-matter engine. Then bolt the engine on a spaceship, use the Dyson Swarm to power a big Mass Driver to push the ship up to speed, then use the anti-matter engine to slow down at your destination. Assuming we can make and store more than single particles of anti-matter, that's not as easy as floating mirrors around the sun.
Dyson spheres and similar variants of them are stupid, wasting the stupidly massive amounts of resources making it and the insane amount of time making it is dumb, plus a civilization may never need to require this much energy
Considering how many million things had to align for a planet earth and life and intelligent life to exist, it seems extremely unlikely there's intelligent life out there that we can ever find and communicate. We're alone, we're unique.
Do alien exist? - Probabilistic yes. Would we know? -No because of the vast distances between starts and low time clash chances. What an astronomer answer?= - Bla bla bla bullshit, bla bal sphere impossible to even exist, bla bla bla... bla
"Know thou that every fixed star hath its own planets, and every planet its own creatures, whose number no man can compute." ~ Gleanings from the Writings of Baha’u’llah, Baha'i Faith
why are we talking about a civilization that builds around a star when you can just make one here and harness the zero point energy field with overunity. iter in france? another one in usa/japan/ germany. the problen with asking people that look "out there" is that they miss all the actual things happening "RIGHT HERE"
Eve pilots, is there nothing we can’t do? We broke their servers with the amount of data we helped cross reference in-game. Coolest thing ever combining space sim gaming and citizen science, glad I’m a part of it.
Someone can explain me where we are in the universe like are planets below us (south pole) and above us? Or where can find a graphic representation of this thanks 👍🏻
I think a better question is why we dont see aliens Space is very chaotic and even we can be wiped by any natural event in mere seconds ask what horrible things that can wipe a planet it pretty damn scary knowing that at any second that passes we are in danger..of extinction by natural means..we are just fortunate to be positioned in a spot where life had all this time to thrive.Where the shear numbers of life should be high per star in the Universe the danger and complexity by right chemical compounds and timing to create the same organisms that started our creation outweigh any such life similar to ours 10000×s over and i was to lazy to add more zeros
Am I the only one that thinks a Dyson Sphere is unbelievable stupid? It would be easier and way better to literally build anything else, like using a mini black hole. A Dyson sphere is stupid anyone that thinks it’s a good idea has no idea what they’re talking about
Also why wouldn’t they have built more efficient technology, I understand there are efficiency limits but if you need a Dyson sphere you’re doing something wrong
Humans are naive to think they are alone in this vast universe. Alternate life will not travel across the vast universe just to crash land on earth, we simply have nothing to offer them.
@@myutubechannel_nr1 who is doing the thinking though? As you read this you are saying the words in your head. You can hear yourself but who is talking and who is listening?
The supposed aliens where held at a base called S4 south of area 51 and that was 30 years ago. People going to area 51 wont find anything except prison sentences and bullets.
Scientists it's funny we've not found any actual sign of aliens untill now, but may be someday we will be able to, which means there's an alien😆 yet to discover.
Michelle Thaller is one of those few people in this world that I can truly say if there were someway one person could live for ever, I would choose her. When she speaks, I listen with awe. She speaks with such passion and knowledge of her field while at the same time staying so down to earth and humble that she can captivate and communicate with anyone while still making the subject matter easier for others to get a grip on. I don't know how she is not more popular, she is an amazing Astrophysicist, and overall human being. I always wanted to be like her, she was really inspiring for me when I was younger.
Welp, the problem is we don’t know how rare life is. We don’t know how life is created. It may not be difficult for life to pop up at all. There may be life all over our own solar system outside of Earth, on Titan, Europa, Mars, or even Venus. Or it may be EXTREMELY hard for life to develop, so much so that this is the only planet it has done so. After all the universe isn’t all that old, only about 14 billion years.
MrNoSleep OSRS I honestly think the governments want to create the illusion that they’re hiding something. Gives people a grander impression of their power. For example if I told you I knew the secret to light speed and you believed me, there’d be a sense of respect and mystery to me now, even if I was lying.
Most scientists work FOR governments, so they say what they're told to say. Those that don't, are treated like a pariah if they go against the "Accepted" government science!
I always thought the Dyson sphere as a weird theory, I mean if they have the technology to build such a big tool that can do that, I’d have thought they’d have the technology to create and use energy way more efficiently than needing to build such a massive thing and harness energy in an oldfashioned way
Moth Girl me too. It’s like how people talk about terraforming another planet. Well if you have all the tech and time then you can do that to your current planet.
Yeah, it is possible that a civilization could go this route. On the other hand, with technology so advanced, and the likely need to gather the minerals to construct such a device from other celestial objects, they would likely have other sophisticated energy sources such as fusion reactors, or even anti-matter reactors. Furthermore, a Dyson sphere of such a size could potentially hinder themselves as they would be blocking light to their own planet. And even if you have a Dyson Sphere, there is a need to transport the energy.... The only reasonable use for a Dyson Sphere would be if such a civilization would live directly of off energy as their nutrition, and they live basically on the Dyson Sphere.
I love how she always exudes such passion and excitement. We will find out soon enough... I still think every day how remarkable it is that we are capable of exploring the stars and think the way we do.
What I CAN'T STAND, is that astrophysicists always explain that we are LOOKING BACK IN TIME. We don't see what's currently out there. There could be a giant interstellar space port between Andromeda and here looking us right in the face. We wouldn't see it. Plus; if you have to choose between an advanced civilization finding us first(as in a long time ago), or us finding them first, who ya gonna put your money on. So they find us (the planet) first, and there's nothing going on, cause we're neanderthals, but they can see the biosphere looks pretty great,....they send a probe.. a lurker probe. Or they flew by during prehistoric time and left a probe.It's all explainable. Screw the Fermi Paradox.There is no paradox. They're out there;we're no big deal; and we're dumb. And no one will ever see this either. But at least I got it off my chest.
It's so clear and understandable, even for dummies and non-native speakers (like me - both). It's like a good friend trying to explain something to you over a beer. It is not easy to convey complicated things clearly and simply. And the speed of light in her eyes freezes time and keeps her young. She is wonderful.
its uncomparable. the more we evolve the more understanding we become towards other spiecies and races and life in general. most people on earth now are still in an ethnocentric stage of development. we're slowly shifting towards worldcentric. next stage will be kosmocentric, which would mean we'll have great compassion and understanding towards all life. integralwithoutborders.net/sites/default/files/resources/Overview%20of%20Developmental%20Levels.pdf
@@satty5030 Advanced alien civilization doesn't have to be unimaginably old and advanced in order to construct objects that can be detected by us. The galaxy is so big that there can be civilizations in it that are vastly more advanced than us that are able to construct massive things, but still not be far from masters of the galaxy. Us humans have so far not build a single structure that can be spotted from a distant star, and we won't be in a long time. I doubt we would ever want to box in our own Sun, given how catastrophic effect that would have on our planet (Assuming there's anything left on Earth to care for by that point). By the time we detect something alien (if we do), that structure will already have to be thousands of years old, which is both wonderful and terrifying at the same time, with no telling what the aliens are up to in the present, if they are even still around. We have our radio signals though, or radiosphere, which potentially can be detected by others, but those haven't travel very far yet, and gets incredibly weak and deluded the further they go.
Neil deGrasse Tyson asked us to ponder the difference between humans and chimps based on roughly 2% difference in genomes. The postulate an additional 2% difference in advance from the human genome. Would we even recognize a being like that? How would we recognize something not even based on DNA or organic chemistry? It boggles m mind.
The problem I see with this Dyson sphere is that we are assuming what an advanced civilization’s technology would be like. When I think of a Dyson sphere, it sounds kind of goofy. You think a civilization that is a million years ahead of us would build huge structures like that to collect energy. That is a 20th century idea. That’s like the Star Trek from the 60s trying to portray what advanced systems would look like in a starship. They got it all wrong with knobs and buttons. They were using a 1960s idea of what the near future would look like and got it completely wrong so what makes us think a super advanced civilization would resort to big bulky structures around stars to harness its energy. It’s just silly.
Reptilian alien I disagree. Take the examples of computers. In the 60s, computers were the size of rooms and were not very efficient. Today, you have more computing power in your pocket than all of nasa’s systems put together during the moon landing. It’s the same principle for this. I seriously doubt a hyper advanced civilization would resort to building star size structures to harness energy. I would think they would be able to exploit anti matter or some exotic form of energy... but then again I’m just assuming as well based on my 21st century knowledge :)
Dyson Spheres/Swarms or any other mega structure to capture solar energy, convert to electricity, and then transmit that electricity where needed is an old fashioned idea. An advanced civilization would likely just rely on fusion reactors for all their electricity. A fusion reactor would be a portable star and require far fewer raw resources than building a Dyson Swarm or similar mega structure to capture solar rays. A civilization that has licked fusion would be rather impossible to detect using the method described in this video.
Fusion is a much older idea than a Dyson Swarm, not that "old fashioned" is an insult if the idea is good. Collecting the energy from our own fusion reactor obviously requires more resources than collecting the energy produce by the largest fusion reactor in our solar system, complete and operating nonstop for free, along with it's own supply (billions of years worth) of fusion fuel. Solar collectors in space are obviously portable, and require very few resources, they can be nearly paper thin. Few to no moving parts, virtually zero maintenance, and can be scaled up to capture thousands of times more energy than we could ever produce with our own fusion reactors. I guess that's the main point, all the reactors we could ever build are insignificant compared to collecting just 1% of our suns output with simple devices. We could MOVE our entire solar system with a Dyson swarm, no future-tech or warp drives needed, just a bunch of collectors and mirrors. Most people assume we will use fusion powered (mostly automated) manufacturing to build the solar collectors, fusion as backup for large solar powered structures, and fusion to move between the stars, but the largest power source in our solar system already exists and is in use today.
@@QarthCEO Because the lightning bolt is free, safe, effectively infinite, incredibly portable, with nearly infinite power range (milliwatt to trillion*trillion watts/second). Why build the expensive and dangerous little spark, carefully maintain it, work to keep it fueled, and deal with its minimum mass limit and narrow power range, if you are inside of a free lightning bolt? Also, lightening bolt tech has been in use for decades, spark tech does not exist. Don't take my word for it, use your internet to learn how the smartest and best educated people on Earth use the lightening bolt in space today, and what they are planning for the future, as the brilliant highly educated woman in the video knows. By the way, my entire home is powered by the lightening bolt right now. No cord needed, though my home needs lots of good ole diesel to move to new places. Power is cheap, simple, and plentiful when the lightening bolt is shining, running A/C, cooking, hot showers, big dual monitors, anything I want. The batteries for night and bad weather are what cost a fucking fortune, are delicate and short-lived to the point I watch them like newborn babies, but I'm not in space. On the other hand, if/when fusion power is possible it won't be portable enough for even my big ass RV.
They would be more advanced than fusion lol, that's our technology level, they probably fully understand the laws of the universe and can get anergy from subatomic world or something, there is energy all around us
From an engineering perspective, a giant cloud of micrometere-size solar collection nanobots would be much simpler than the huge scaffolded structure we imagine based on our current technology. This programmable cloud of nanobots would require zero maintenance because they could be generated on a continuous basis and inserted into a stellar orbit timed to let them fall into the star itself at the end of their projected lifetime. Let's call it a Powercloud, or something way better. Try to marry nebula with solar in a made up word. And, let's keep in mind that actual blueprints for myriad nanobots serving as many functions have ALREADY been drawn up. These mini-machines currently await our engineering of the necessary technology to build them. So, it could still be aliens, unless they grey goo theory is true, in which case we should burn all those blueprints.
The problem with the Dyson sphere is: Where would an advance civilization get the materials (especially metals) to build this unbelievably HUGE structure? There isn’t enough materials on Earth to make a livable ring orbiting our own planet, even less a sphere around it, and a ring or sphere around a star would span the length of THE ORBIT of a planet; likely billions of times longer than an orbit around an Earth like planet. So the only way an advanced civilization could get the materials is by being able to travel to THOUSANDS, if not millions, of other Earths (Or super-Earth, IF they are able to count or circumvent the increased gravity of that world) to mine the ore they’d need to build the structure. Now, knowing what we know of the energy requirement for interstellar travel and if we follow our example logically, it becomes evident that such hypothetical advanced society basically would have to have already found an incredibly abundant source of energy to be able to travel those distances, which would bring into question whether they would really need that much more energy that they would consider such a humongous undertaking worthwhile (Not to mention the sheer amount of manpower required to construct such a thing in less than… Oh, let’s say: A thousand generations?... I mean: Even a Trump dynasty can’t stay in power that long enough to impose such a “space force” project on its people!). So, how about shoving the Dyson sphere back into the sci-fi side of possibilities and concentrating on much, MUCH more plausible detectable signs of life in the universe?
Space is such a vast and hostile thing, more inclined to kill us than nurture us. I suspect life out there might be more like H. R. Giger's Alien, rather than anything fluffy and friendly. Mind you, if a flying-saucer lands, and something akin to a cuddly shih-tzu pops its head out, I take it all back. 😁
Surely building a massive structure around a star would block all the sunlight out for all the star's planets. That would be silly as the people that made the structure would be without light themselves on their own planet....
we humans have only existed for a blink of an eye Considering the age of the universe and the age of the earth. So wouldn't be possible that at this short time of existance we could be alone? Maybe life has existed before us and jas already gone extinct and/or maybe the next life is yet to develope
This is a strong possibility. I would add that even if there were other advanced civilizations, the distances and sheer numbers of stars and planets would be prohibitive. Even a civilization much more advanced than ours in the Milky Way galaxy, a civilization with the ability to traverse wormholes or travel using something like warp drives, might have a difficult time finding us among the hundreds of billions of stars and the trillions of planets just in this galaxy -- all spread out over tens of thousands of light-years. Just think of how long it might take to map and visit 10,000 solar systems, and that would give you an idea of how huge it would be to try to do that on a scale of hundreds of billions. And that is just in our galaxy. There are hundreds of billions or trillions of galaxies out there in the observable universe. And what about what is beyond the observable universe? For what it's worth, I strongly believe we are the aliens on planet Earth. Folklore for many peoples from the Middle East to the indigenous peoples of the Americas suggest that human life was brought to Earth in the far distant past.
That Kro Kro Bird Future of intelligent life on earth is AGI not humanity, which will surpass us in every way imaginable. All our sci-fi and thinking of humans flying around the cosmos is a story as old as humanity-human hubris. Human are smart monkeys that it. We are not Gods and we are not the future long term.
Just because we think a Dyson Sphere is the way a technologically advanced alien civilization ought to harness energy does not make it so. And more likely such an advance society would have come up with a means of meeting their energy needs that are beyond our current understanding.
Cuando una civilización tiene un sol miles de veces más grande qué nuestro sol y tecnología miles de años más adelante, creó que pueden hacer muchas cosas con un pequeño sol y un diminuto planeta llamado tierra 🤔eso creo yo.
Is there life, yes. We are here so it must have happened again and again. Now what counts as intelligent? What if they don’t go into space by choice but they are not actively destroying their world? Hmmm
The number of different Aliens is great!... But the vastness of space/time is even greater!... Therefore, for all intents and purposes, there are no Aliens!...
Stupid logic. 😂 The size of the Universe suggests there is intelligent alien life out there, and so much of it that our galaxy might have 100s of thousands of them.
With a trillion, trillion stars out there, each with numerous planets of course there are countless other civilisations in the universe. Problem is the distances are too far ever to visit or communicate with them only in science fiction.
39devonshire This is my favorite comment ever on all of RU-vid. I’m being serious. Nobody ever says this but I believe it to be true, so true and to the point. Namaste 🌈
The reason we haven't been able to prove that other life exists is because we are in the simulation where the creator is too bothered to put lives on other spaces.
Wonder if anyone ever thought that it may not be the best idea to send out a box with information about earth and explaining where we are located out into space to hopefully be found by extraterrestrials.. I mean we really don't know anything about them, could either go really good or really really bad. Just a thought.
Personally, she reminds me of why we should all stay interested in our natural world. Sparks the joy I had as a child, and made me want to go to space camp. While reaffirming the realist in me that led me to be a damn good nuclear electrician. I think it's awesome that these videos are produced, and shown in public schools. Plus uploaded here for everyone.
This Universe is fractal design and where there is one, another will fellow!!! We have here amongst trillions of galaxies, stars and planets. We are not alone but great distances keep us apart!!! Perhaps it was made so!!!!
So that star at 60 light years sounds a good candidate for looking for evidence of transuranium elements which are supposedly articificially made and therefore don't exist elsewhere in the universe. It's proximity would make it much easier to detect such spectra.
1:04 See, to me, it’s not too wild of an idea that life could be out there, because we had dinosaurs here on earth, I can only imagine there might be dinosaurs planets out there floating around in space. Indeed, oceans on other habitable planets are probably filled with wild life.
hi my name is Robel Bizuneh from Ethiopia watching this video and I wonder what she thinks about the documentary called "close encounters with the 5th kind" and dr steven greer? If you can please ask her opinion on that subject because we have no other way of interacting with Michelle Thaller to ask her this question and get us back with a video. please do this for me..............
"would we know"? Probably only by chance with our current technology. With huge astronomical distances separating galaxies it must be like using a simple telescope to find a single ant on the other side of the Earth. Even our own Milky Way is 100,000 light years across & our Sun is located in the spiral arm of the Orion constellation, just one of 88 constellations in our galaxy. The distances are huge & our blue dot is infinitesimally tiny by comparison. Whilst we can determine the geography & chemical composition of our companion planets/moons, we still don't know if any life exists there - so it's obviously many orders of magnitude harder to determine this for the planetary bodies outside our solar system, unless we see something looking at us!
A dyson sphere is great for science fiction but impractical to impossible in reality. The first issue is where do you get the matetial to build it? Even if you could build it with rock, it would likely take more material than exists in the system. The second issue is what do you do with the energy after you collect it? Send it somewhere? Well the star is already doing that, solar cells are by far more cost effective (keep in mind an advanced civilization will likely have much more efficient solar cells) way to collect the energy. As far as aliens go, no one knows. If anyone says otherwise then don't believe them. We could be alone or there could be life in any number of places. The problem is too many scientists "feel" there could be life, which is quite unscientific. Just to make up some numbers, if theres 10^50 planets in the universe and the chances of life forming is 10^51 then it is very likely that we are alone. But no one knows the chances of life forming or can even guess. We can guess at the number of planets in the observable universe but a half equation is useless. Another issuse is if the life is intelligent. There could be lots of planets with dinosaurs and little to one with intelligent life. Or there could be lots of planets with bacteria and no cells with mitochondria. Theres so many places that may make us a one off. Also interstellar travel could be impractical to impossible. Faster than light travel may not be possible. That would mean a travel time of about 10,000 years give or take several thousand. So generations would have to survive in 0 g, which we may or may not be able to evolve to survive. You would need tons of water since no system that recycles is 100%. You would need raw materials and a machine shop because lots of repairs would be needed in the time it would take. There's plenty of other issues but i hope you get the point. Also we have been in a great period of growth. As climate change drives a mass extinction we will likely be in a civilization collapse similar to the bronze age collapse. We can only speculate on what will happen. Most of the internet sites will go away. Probably most airlines. Nobody's gonna care much about oil, people will be fighting for food so no one is gonna care about space travel. Look how far away the moon is and nobody lives there and we were there 50 years ago. It is unlikely we will ever go to a planet outside the solar system. I dont expect to see any aliens arrive here either.
We cannot rid the world of covid together. The skies are free to all to see. Scientists wouldn't cover up a discovery... Just some of the takeaways from this living genius! ✌🏽❤️
Something about those Keppler numbers doesn't make sense. As Michelle points out in order to detect a transit the orbital plane of the target system must be oriented edge on to our point of view, within an angular tolerance of the angle subtended by the disc of the target star. Quick back-of-the-envelope calcs suggests that out of a sample size of 200,000 stars (as she referenced) there should only be, at the most, 1 or 2 possible detections, Yet she indicated there had been thousands. Something doesn't add up.
Ofcourse we do appreciate all of the science but just for once I wish a real organized scientist would turn other way and research more in great depth about our spiritual science more than anything else they have ever did in the human history! Because there is something out there that scientist can't fully explain and understand about spiritual world. Not nice just to say your an atheist and turn your back. Likewise God bless Michelle!!!
A more advanced civilization will be more energy efficient. Wrapping a star is the idea at our current technological level. The advanced civilization will have more ways to get their energy needs. They will use much less to do more. Maybe they get their energy from more abundant dark energy - whatever that is.
Aren't time scales important? Humans have only been signalling to the cosmos and looking for a century. A life form sending signals we receive and understand could already have been extinct for millions of years. At this point in our evolution isn't it more important that we preserve the biosphere of the only planet we have?
The whole idea of a Dyson Sphere never seemed possible to me. All of earth does not have enough matter to build such a structure. Stars are so much bigger than planets it would be impossible.
You'd have to mine several asteroids to build a Dyson sphere. But even Freeman Dyson hated the idea and regrets his name is associated to the Dyson sphere.
The sky is a computer screen . I’m sorry most of you are sleeping and can’t see it for what it is . Yes we are living in a hologram computer simulation game. But it still feels amazingly awesome 💎
life probably exists at various degrees of technological advancements...not necessarily advanced then earth...its just that they are probably too far to get detected..
Hi Michelle, there's been a lot said about space-time deformation, is there a particular direction to the dent or is it in all directions. We always see a downward bending in the CGI presentations
I really hope that the alien doesn't exist or we won't encounter them in the near future. This is super scary shit, people can’t even live peacefully together on one planet, we don't need an extraterrestrial civilization.
