Could Dyson spheres exist in our galaxy? 

Even if we had this technology, people would complain about job losses in fossil fuel industry.

Everyone: read between the lines. This is what disclosure looks like - slow drip of normalizing the fact we are not alone.

First thing we need to do is figure out how to get ourselves out of our social/political internet silos.

Even if technolgically possible, human greed would not let it happen.

Great, now create a way to for us all to eat and live free.

The Prime Directive forbids any Star Trek civilizations from making themselves known to us.

Possibly but it's probably redundant. If a civilization can create a Dyson sphere they can probably create a way to harness energy without that much resources

How are we Type 0 yet we’ve invented The Rotato electric potato peeler

Our divisiveness is what's slowing down our technological advancements.

Couldn't you find anybody else presenting these news. Feels like he's talking to kindergarten kids.

Always a pleasure to be talked to like we're three.

Thought that's a new line of vacuum cleaner for a sec 😅

So where would you get all that material to enclose the sun? and how are you going to maintain repairs for such a large object?

Them talking about thinking theirs advanced alien civilizations is wild. We almost close to the truth

Michio i hope you live long enough to see the results of your research this will be a crazy age for science

Dyson Spheres? not likely. Dyson Mesh? Quite possible. The lead picture shows a mesh.

Where would we get all that material from? It would take multiple planets to build around the sun.

Please note that Arxiv is an open-sourced preprint platform, which means the paper is not peer-reviewed by other scientists of the respective field yet. As exciting the finding might sound, I would take this with a grain of salt.

Going from L1 to L2 may only take a millennium or less. Not millions of years. I'm on record as predicting we become L1 in the next 50 years.

He got his Star Treks messed up. They were a type 3 civilization.

I never understood why a Dyson sphere would be necessary when panels in space can collect more than enough energy for our needs (think ISS). Shouldn't we be looking for unusually dim planets instead?

If the aliens had advanced tech they could create all the power they need from a single one inch chip .

Blind, blushing, and compassionate.. the presenter of the program, Azza.. is trying to show the crazy genius of Micho Czco

When a civilization has advanced enough to produce technology to enable the ability to encapsulate a star they by that time would surely have aquired the knowledge to produce simpler and more cost effective forms of energy production. This makes Dyson spheres a moot thought.

Dyson was actually embarrassed when people found out about his idea!

These channels bring me back to those days when I was in Kindergarten discussing space fabric and quantum physics. 🙂

A dyson spear with a thickness of only 100cm at the distance of Neptune (at it farest point in the orbit) would require 18.7 times the matter contained in the solar system.

Artificial intelligence will be key in getting to the type 1 and subsequently 2 . We are starting to scratch the surface.

i built one but nobody cared, now i can't remember where I left it.

Didnt we just find a planet with 1

Even in Star Trek (since Michio invoked it), the Vulcans were aware of our existence but didn't consider us worth contacting until we broke the speed-of-light barrier. In that fictional universe, we did it by developing warp drive, but if it really is possible, we'll probably do it with communication signals first and SETI won't hear anything until we do.

Where would they get enough Iron and other metals plus the knowledge to create a Dyson Sphere?

That's a stupid question? Yes! Schrodinger's equation proved that anything is possible all the time. We call it a fundamental law for a reason.

Even if an alien had the capability to build this technology, they might choose not too. I just have a feeling there would be a lot of unexpected consequences from doing this.

They make an awesome Vacuum, why not

Agriculture (with external matter) enabled civilization. Industrialization (with external energy) expanded it worldwide. Computerization (with external information devices) buffered the shock of crashing the planetary limits. AI-nization (with the software to find & utilize causality) will promise sustainable development. However, energy consumption will be the most detectable indicator from a vast distance.

“We’re type 0” . That’s obvious!

just steal it from the aliens

What ever happened to Journalism? Dyson got the idea from a science fiction story called Star Maker written in 1937. The writer of this story couldn’t spend 30 seconds reading Wikipedia? Sheesh.

Actually, he just developed an idea that appeared in a science fiction novel called 'Star Maker' in 1937 by author Olaf Stapledon.

When humankind has the technology to build a Dyson Sphere, it would already be obsolete for generating energy.

Terrence Howard will set us all free 🙌

They can just make a portable sun, they don't need a Dyson Sphere

This is really exciting news!

I bet they don't treat each other as we do.

KARDASHEV SCALE: [The measure was proposed by Soviet astronomer Nikolai Kardashev (1932-2019) in 1964 and was named after him.] Type I Civilization (Planetary Civilization): This type of civilization can use and store all of the energy available on its home planet. This includes harnessing energy from the planet’s natural resources, such as solar, wind, geothermal, and other forms of renewable energy. Type II Civilization (Stellar Civilization): A Type II civilization can harness the total energy output of its star. This could be achieved through structures like a Dyson Sphere, a hypothetical megastructure that would encompass a star and capture a large percentage of its power output. Type III Civilization (Galactic Civilization): This type of civilization can control energy on the scale of its entire galaxy. It would have access to the energy produced by billions of stars across the galaxy, implying an advanced level of technological and possibly social development. Type IV Civilization: This civilization would be able to harness the energy of an entire universe. Type V Civilization: This civilization could harness the energy of multiple universes and multi-dimensions.

US Government: Unlimited energy from the sun? 200% tax on energy.

It's self contradictory..if you can build a structure this big, you have likely already solved energy issues and have secured a basically unlimited power supply which would make this structure unnecessary.

the amout of any specific material that totals millions of planets and being able to process it on such a scale that you can collect plannets and smelt them down makes me think that size being probably wouldn't need to do that. where would they store the energy, maybe it's already stored and contained in it's space.

It is a sphere, not a black hole.

The amount of resources you would need to create such a device is insane There isn’t enough material on this planet let only our solar system But that’s what people do best strip everything they can out of something

Why is there Dyson sphere videos everywhere

Kaku is getting kuku. Where will you get all the material needed to build a Dyson Sphere ?

Dyson's sci fi idea from the 1960's seems far fetched to me. I think the idea of passively collecting heat & solar radiation from a star from an efficiency standpoint in an advanced civilization, considering the amount of raw materials needed to build said sphere is far less efficient than actually creating our own "star reactors" using nuclear fusion and a minimal of materials to encase that reactor. In theory, if you were to take the amount of material (say a planet the size of Jupiter it's been estimated) to mine all that resources, build the sphere - would you actually have more or less energy than dedicated fusion reactors? Imagine how many fleets of THOUSANDS of starships you could build, each with their own fusion reactor, vs a single Dyson sphere or even more ridiculous - one that encases an entire Galaxy. I think a Dyson sphere might only be likely if a civilization lost it's home planet due to a catastrophic circumstance and the entire civilization lives on Space ships orbiting their sun, because realistically, without warp drive, the civilization would long be dead before reaching another habitable planet. And thus, a civilization that has a Dyson sphere/Dyson Swarm is more likely to not have a faster than light drive technology. Otherwise, it would be far more efficient to explore other star systems and find habitable planets to send a colony fleet to colonize.

The amount of physical matter to construct even a Dyson cloud is enormous. All the planets in our solar system would not be enough physical matter to construct it. It would take all the asteroids to be collected, processed and fabricated into useable matter and form.

I have one in my backyard. Its a dyson sucker sphere. Sucks everything up around

The idea that the more advanced a civilisation is the more outwardly evident it must be through advanced material technological innovation seems so much of a fallacy to me. I can envision a world of truly advanced beings whom have transcended any reliance on material advancement and have instead sought to seek or have in fact uncovered a state of being that doesn't rely on excessive pursuits or gathering of conventional external energy but instead looks within the mind and self to unravel a sense of peace, pleasure and contant with existing.

What tripe. We could start building one today. Could vs the will/economy/cooperation of course. And the illustrations are crud. Could have done them on a 90s PC with TrueSpace. A real "Stapledon Swarm" vs a fictional Dyson Sphere is merely many thousands of solar collectors, power plants and even mirrors that orbit around their star, collecting light for power or beaming it elswhere for heat, illumination or to other power generators. They'd start up with a few small projects, such as to beam power to probes and far stations or power solar sails - then they'd do things like add light to their equivalent of Mars or block light from their equivalent of Venus. Eventually the star would dim a bit vs real mass and brightness to an outside observer. The term is from Olaf Stapledon - "Star Maker" among many other epic sci-fi works and Dyson himself was inspired and wanted to use that term. The 70s era megastructure scifi fantasies had things like Niven's Ringworld or other huge full shell Dyson Spheres. Those did require ultratech and if a high tech civilization wanted it they had tech that meant they didn't need it. For example a full ring or full shell especially would have net Zero gravitic attraction to their star and need antigravity (level 3 or level 4) tech to avoid either drifting away or a catastrophic collision. What likely happened is over time plenty of advanced (our level or a little above) civs had attractive worlds but too cold, too hot, too dark and so setup mirrors and stations to use their star's wasted power. Over thousands of years they indeed red shifted the star. BTW - if a civilization that builds one lives a long time when their star expands then contracts they could adjust the Stapledon shell to expand/contract with it since its not one piece but many thousands of networked islands.

I thought Dyson released new product?

Theoretically though, primitive civilisations could leapfrog thousands/millions of years of 'organic innovation' if they came in contact with a more advanced civilization and simply absorbed their knowledge.

What if the earth itself is a Dyson sphere

a dyson swarm is more practical and realistic since it requires far less resources than a sphere and can be completed a little bit at a time

We aren't warp capable so the Prime Directive would apply.

If we can harvest metal in other planets or in meteorites then I think we can build that Dyson

This star has people mold on it

A Dyson Sphere emitting any heat I would think is a broken Dyson Sphere. Would be a waste of heat energy.

Could they? Sure, do they? We probably wouldnt even know it.

What if the civilization made the Dyson sphere not heat up

How could you possibly harness that power though? My brain fails to understand how you go from capturing that energy, then using it on the home planet.

The mass of the sphere would have to be larger than the mass of the star... which would never exist

There are Rubik’s Cube universes out there now, all unsolved! 👍

I think we in order for us to reach type 1 civilization we need a genius scientist as a president

By the time when the AGI gonna be real very soon, we will be able to become Type 1 in just 50 years.

But what type of star??????

No chance. The inventor would be “Boeinged” by the oil companies.

That's a nice middle ground. Not nothing, and not everywhere. Seeing Dyson Spheres everywhere would be creepy.

If we even had the technology to pull this off, wouldn't it take several thousand years to build? Would we even have enough resources on just the planet earth or would we have to harvest other planets for the resources? Let alone where the heck would you find all the manpower for such an inconceivably large and complex project? Millions of years more advanced, yeah I'd agree with that sentiment.

Wouldnt it melt the sphere over time

These ppl have said everything except for the words "Yes, we know definitively that other intelligent life exists in the universe." They told us they think Oumouamoua was a probe. They told us that a mothership could be lurking somewhere in the solar system. And now theyre saying they could or may have detected dyson spheres. Even if theyre saying they could detect them and havent, why are you looking for this type of technology from such an advanced civilization when, as far as theyve told the public, we havent found even primitive life in the universe?

We’re type zero where we play with ourselves

Where would the tremendous amount of mass needed come from?

Highly advance civilizations laughing saying l: yeah milking a star, why not steam engines 😂

Some say Dyson rings, but it would be plates. I would take longer than the stars life to cover it like that unless you could inject particles into it and keep fusion going. In that case the star would be covered and you wouldn't see it, not even the heat of said star. Because that would be energy that would be used as well. 2+2=4

To gather the materials, the energy efficiency, construction requirements, gravity control for movement and structure stability. We are looking at civilizations that would have to develop a plethora of incredible technology long before even conceiving of building such a thing. A world ship in a stable orbit housing trillions could be hard for our satellites to detect yet alone would be hundreds of thousands if not more so years more advanced than Earth is. Honestly I feel we keep looking for these things because such massive things are all we'd be able to see. Like shining a flash light into a dark ware house, we can see the chairs just fine but a bug crawling on a far wall we can't make out. There could be trillions of system wide civilizations, continent sized colony ships, and more out there and we simply can't see them because they are too small to make out from so far away. That said I want to hear how far away these are because if a Dyson sphere is found and it's 10000 light years away that would mean something out there built something that insane when humans were just figuring out grain and domesticated goats. If they are still out there they are ten thousand years past when they built it now.

"Star Killer Base" seems like such a waste of resources. Why harvest the star, then fire the energy at the planets surrounding it? The planets would spin off or whatever. Still destroying the solar system.

What would this be made of that when that close to the sun wouldn't melt or be destroyed?

We will never be a Type I Civ. For every 1 step we take forward, we take 3 back. 182/194 countries on Earth are currently involved in conflict, climate change is worsening, and we're doing nothing to stop the 6th mass extinction. I would love to be a Type I, but it's just not in the cards for us. Not at this time.

We are pretty much in the last extinction due to trashing our planet.

I think there’s too many available planets to thrive on to have to build something like this. So no

That is scary....

basically on the Kardashev scale, it would be a class 2 civilization.

A Dyson sphere is actually really inefficient. An advancing civilization will always try to minimize not maximize their technology. You want have more power but have it smaller than make it a lot bigger.

Imagine the looks of alien face when we become interstellar,,, lol it’s a party now

ya right

We, on Earth, are like a ship in the night. A Dyson Sphere/Swarm would be akin to a lighthouse, no? (lose, methaphorical symbolism y'all)

Only if he stops making vacuum cleaners.

<a href="#" class="seekto" data-time="13">0:13</a> Nah, that isn't what he said. He was thinking that maybe it can be a way to search for advanced life. Meaning, maybe we can spot a star with something like that around its star. Something that might be easy to detect. He wasn't even taking it very serious. More 'Smart man talks' then 'Dumb people totally miss the point/intent'. I don't even think it was his idea. I think it was something from a sci-fi book. And the nodes in your sphere are bigger than the Earth lol Where are you getting the recourses. We couldn't even build one of the nodes.

There are some of us who want to progress and there are some who want to stagnate, conserve the past... when has stagnation ever worked for a person? a business? a country? a civilization? Forward or backward, the choice our species faces.

Um is this real??? They talk so calmly as if it’s just another day - if we found aliens, that’s world changing.

Ha you fools told me not to invest in their vacuums 😂😂😂😂
