Aliens "Shit they can see us. Oh they think randomly dimming stars are natural, good we don't have to talk to them yet"
Always presume the most plausible but prepared for the improbable
@Gary Hochstetler there's one less bright star in Pleiades constellation nowadays, for example.
@Gary Hochstetler to be honest, I don't now, but it was depicted differently during the bronze and early iron age. During the bronze age the celestial motifs were all over the place because of agriculture, and iron was originally a "star metal" gained from meteorites, as ore from Earth itself required more difficult approach.
And now, one of the stars (or, possibly, a clump of those stars seen as one) shown there is gone.
There are others, but this is the one I know of.
@Gary Hochstetler And when, exactly, did I say it couldn't be natural? Whatever it was, it happened before humanity even came to exist in the first place.
Honestly i don't blame them

I think a Dyson swarm has one big advantage: when the time comes to pack things up and run it would be much faster than dismantling a Dyson sphere. It could be rearranged away from the star during the supernova blast and wait for the star to become a white dwarf to rearrange it again.
Sol isn't gonna go supernova iirc, but it's still gonna grow giant so yeah still a good plan lol
Sun-sized stars don't supernova, they make planetary nebulae. Stars need to be at LEAST 8 times as massive as the sun.
I think you underestimate the size of the bang that the sun will make when it dies. We'll want to be very far away, and the swarm might just have to be left behind
Or we can make stars go supernova and extract all the energy from the blast
I think just a single nuke would be enough to dismantle a Dyson sphere it doesn’t even have to damage it much just knock it off balance so the sun will swallow it

This is the truest statement I've ever seen written. I fear we don't have very much more time to figure it out and are cutting that time down with every birth. We speak of equality and merit but only practice in-group and relations. The world today produces approximately $6500/year of "value" yet half don't make that much and a 10,000th of us make much much more. Until we learn that all basic needs of the people must be met and we agree to lower our numbers to a sustainable level we are heading to the end of the HUMAN RACE. And it is most likely already too late since we use up the Earth 3 times faster than it can heal itself. Too bad we couldn't grow up as a people instead of concentrating our efforts for the few at the expense of all of us.

The solar wind info is understated, thanks for covering that. If the shell were of uniform thickness, you'd experience only the Sun's gravity when inside the shell. This basically mean all the energy you're trapping arrives beneath your feet.
The shell idea is basically like levelling your own house so that you can never pay for utility bills ever again.
It’s like leveling your house so you could build a solar panel big enough to power your (now non-existent) house

5:53 What in the universe is a watt per second? A watt is one joule per second, which is a measurement of power.
Acceleration?
Good timing for this video! A game called Dyson Sphere Program just entered Steam Early Access. It's sort of like Factorio and Satisfactory had a baby, and that baby decided to build a giant ball to play with. You pick a random star cluster with up to 64 solar systems to mine for resources. They even have neutron stars and black holes, though I am not sure what those do,
What's that one planet called again?
One sec. Its uh. Its... Earth
I'm open to corrections, but I heard somowhere it's something like Œrth... I guess?
"Erf". Which is also, coincidentally, the sound I make when I drop my peanut butter sandwich. It must be a very disappointing place.
Why does everyone on earth keep forgetting that planet name? Smh
Erf. Ers. Ehrve...
5:55 Watts per second is a misnomer. Watts already measure the rate of energy use.
Correct
Watts is Joules per second right??
Oh god my Thermo prof will kill me.

@@Lefygrens It's the acceleration of power production/consumption!

Joe, you should upload these as podcasts on Spotify, would be awesome.
In Avengers Infiniti Wars Thor and rocket got to a Dyson sphere essentially to forge stormbreaker.
it kinda was a dyson sphere wasn't it?
Interesting theory. Good one mate!
@@heliveruscalion9124 it totally was. But a pretty stupid one because it was only used for one forge. I mean fuck they could have used the energy for so much more but nope they used it for that one forge.
On a much substantially smaller scale because it was around a neutron star, orders of magnitude smaller than the star we refer to as “the sun,” but exponentially more energy output I think is the case. Not 100% sure so don’t proceed to roast me if I’m mistaken.
Note to future humans (or post-humans): Build the Dyson Swarm for all of your energy needs, but keep the earth intact and use it as a giant living history museum.
Unless future humans can pull matter out of other dimentions, they will need to use earth for building materials to build that sphere. and probably all the rest our solar systems planets.
What history would that be? Snowball Earth? Without the Sun Earth is dying, and if you build the swarm far enough out to enable Earth to be within its orbit, you A) defeat the entire object, and B) throw all sorts of additional gravitational equations into the mix.
Elon Musk thinks all industrial should be done off planet. So you arent the only one with that mindset.
@@saladinbob If they can build a dyson sphere, they can used portion of those energy to artificially light and warm Earth if they want by using other fantastic technologies that we can't even imagine of at that point.

@Brenden Heitzman yes, we're all aware of that, thank you.
When I imagine a dyson sphere my head goes straight to the Death Star.
We'll build a Death Star, LONG before we have enough raw material to reach out to Earth's orbit, in all three dimensions!
i always thought The Kardashev scale should have more tiers like 1 and 2 great but to jump to 3 as galactic is a massive leap why not level 3 being the energy equivalent of your local star cluster or of a blackhole
I think the idea was that it would be something similar to a log scale (which is often useful when you get into really large ranges of values anyway). That is, each step on the scale doesn't _add_ to the previous, it _multiplies_ it by a given factor each time.
But of course the values used for the different steps are arguably kinda arbitrary, so they're not really totally consistent with a log progression either. I did think some time back about trying to develop a similar scale that was actually internally numerically consistent, but never did get around to really trying...
(I also think it'd be cool to have a scale that reflected appropriate numbers for earlier civilizations too (i.e. "harness the energy of a wood fire", "harness the energy of a continent", etc)...)
The fact that we never found a Dyson sphere might prove that we are alone .... or just that it is a very dumb idea and that they all have better solutions once they reach a point of technology where they could build one.
Or that we just wouldn't be able to see it as it would be covering their star... Or that its just a very dumb idea.
@@86BuzzSaw You know, if we think that they would build a Dyson sphere we also assume that they would need a constant flow of energy equal to a sun. I mean ... what the actual F would they be doing? Charging a billion electrically driven space ships? But while charging the space ships their home planet would be in the dark?
I am very sorry but Dyson was a moron - as proven by all the aliens out there NOT building his sphere!
We are definitely not alone and a dyson sphere cannot be built

How could we ever evolve like this if we’re constantly at war with eachother? In order for this to happen humanity has to understand life and stop killing eachother.
Actually, internet wouldn't exist without WW2
War has always been and probably will always be a big part of our species, we advance technology much faster during wartime and on the downside people die
War and death makes people determined to make technology to stop the war and death. Then wars break out because of the advanced technology which causes death, which makes people determined to stop the war and death. War is a bad time for life, but a good time for technological advances. Plus, even with stuff like this, in the past years, technology has been advancing way more quickly. 100 years ago, we had basically nothing, and shitty living conditions and jobs. 50 years ago, we had some cars and guns being made, with the first computers being made. 20 years ago, we had shitty computers that could run pong or solitaire at best. 10 years ago, decent phones and computers and consoles, games like Skyrim. 5 years ago, we made drones and such. A year ago to today, we now have computers that can store terabytes of data easily, and drones that we can fly on, along with actual retractable plasma based lightsabers, and random people in their garage making laser cannons. Within 10 years, we could probably make something akin to the first iron man suit, without the missiles. Even with horrible conditions, there are those few people that keep on making awesome advances.
Wars actually are the driving force of innovation. True wars are shit, but we would not have technology we have now if it wasn't for war!
That will require one nation to rule the world.

Isaac Arthur: Will we build a dyson sphere around each star or just around most stars?
@Click Bait let’s build one around our planet
@@cactichris9829 a little counter productive but you go the spirit
I wondered how far down the comments section I'd need to go before seeing Isaac's name. Answer - second comment down 😆
Isaac Arthur is quite out-there but it's nice thinking about the far (far) future. Event Horizon is also a great podcast by John Michael Godier. Sublime subjects for an old, curious guy like me.
The sun is a relatively quite and calm star. I guess building Dyson spheres around more active stars will be a bit more challenging.
Yep, what Dyson originally meant wasn't a _solid sphere,_ but something now referred to in sci-fi as a "Dyson Swarm". The Orion's Arm Universe Project makes heavy use of spherical Dyson Swarms, as well as Dyson Swarms in other geometries.
So, I actually met Freeman Dyson, back when I was in grad-school for physics. [One of the professors in my department knew Dyson, and managed to get him to visit and give a colloquium.] I found him quite humble, and he was a bit perplexed that we were all so honored and impressed to meet him.
5:53 I'm no physics expert, but does Watts/s make sense in this context? Wouldn't it just be Watts, since we are talking about power and not the increase of power?
Yeah i think its either just watts or joule per second
Mercury has feelings too....and its crying because its surface temperature is 430 *C....we should really release it from its pain...
Agreed, lets help it find its purpose in life.
2121 be like: micro life on mercury be suffering. STOP THE SPHERE. STOP THE SPHERE! lol and then all we will be rolling in our graves!
Yes let's end its suffering... by destroying it ourselves
It's like 0 degrees on average, 130 + or - depending on the time.
Yes it's in celsius.
*whispers* "the mormons were right!" 😂
(My family is LDS, so I find this reference very funny)
I mean, if any Religion is correct it'd be Mormonism. It's the only religion with a logical cosmology and follow through, and purpose of life. Other religions effectively believe in Damnation as a heaven- Damnation being the lack of eternal progress and growth. So if that's you're view of heaven then congrats, that's the heaven Mormons believe you'll get even if you don't follow Mormonism (A heaven without eternal growth. And the lowest tier *may* even be a heaven with blackjack and hookers), just that there is a higher purpose above that eternal life. And the purpose of life is to grow up to become like their predecessor / father / parent. Humans -> Gods.

Q. Could Humans actually build a Dyson sphere? A. No. video ends at 6 seconds.
Correct Answer is : Not Currently.... video ends in ten ....
We can but not now
@@martin3288 I dont think you grasp the scale. The surface area of the sun is 6,000,000,000,000 square kilometres. If you could cover 1 kilometer per second, it would take 190,000 years.
And a Dyson Sphere would need to be built millions of miles from the sun, meaning the area needed to be covered orders of magnitude bigger. Its simple not possible. It would require the resources of millions of solar systems and could not be completed in any kind of realistic timeframe.
@@squirrelofdoom3830 huh you sound like the people who said we would never leave the planet.
@@MrBakersown Not really. See there is a difference in speculating about the theoretical possibility of say, interstellar travel and something that is just ridiculous. A dyson Sphere is proposed to be built 1 AU unit from the star, meaning the surface area would be about 29 trillion square kilometres. Or about 57000 times the area of the Earths surface.
Where are you going to get the trillions of tons of metal and glass and cable from?
If you had access to the raw material, and we could produce 1,000,000 square kms of the Sphere per day, it would take 77000 years just for the manufacturing.

Aaaaand it goes to 2021 recap episode.
Joe sort of hinted at this, but it seems to me that by the time we're capable of far-future technologies like Dyson swarms, or even sending large payloads (like humans and life support systems) on interstellar voyages, we probably won't need these technologies, as simulating minds (either through mind uploading or good old-fashioned AI) is a much easier problem to solve, and would likely reduce the energy needs of our civilization and the need for large payloads to send intelligent beings to other stars.
There is the scenario in Charles Stross' Accelerando where our solar system is taken over by essentially a ravenous A.I. virus that does dismantle all planets and moons to create a Dyson swarm, but presumably if future "life" is intelligent and posthuman, it can train itself or reprogram its own minds to restrain these impulses in favor of sustainability.

This is a very thought provoking video!
The idea of uploading human consciousness into a computer makes me wonder what kind of experiments (outside of any kind of “Turing Test”, which at best could only confirm that the information content alone in a test subject’s brain has been uploaded) could confirm that the test subject’s conscious awareness has been transferred to the computer.
It would be great to have a reliable alternative for survival (e.g., as a computer upload) if some life threatening problem with the Dyson Sphere technology should occur.
What kinds of experiments? Only one needed, just a have spouse or sibling ask it a very personal question that no one else could possibly know!

Thank you Joe! Great insight as always and just signed up to Nebula etc.. great for a geek like me!! Great to know a bit more about Dyson spheres after the introduction in the Bobiverse.. another great geek fest!!..Speaking of space stuff... Hope to see more UK colabs with Dr Becky as well.. 😁
Funny. There is a game coming out in a week called "The Dyson Sphere Project" where you play a robot flying through the galaxy to build factories that harvest resources of planets to build a dyson sphere. Even more funny is the background story. Humanity build a supercomputer that is able to create a true virtual reality for humanity to live in, but it needs so much power that only a dyson sphere can support it.
Considering that in less than 100 years we went from crawling on the ground to visiting the Moon....5 BILLION years sounds like enough time.
But all Earth's multicellular life will be dead in about 1 billion years because, ironically, there will be no CO2 in the atmosphere - which means no plant life. Only non-photosynthesis/extremophile bacteria will be able to survive then.
But yeah, 1 billion years is time enough.
@@sunnyjim1355 letting our star run its natural course won't happen unless we die out anyway. we should be able to remove heavy elements from our star via star lifting and we can add more hydrogen if we want to extend its lifetime. not that we would necessarily want to as stars are likely not the most efficient way to create and store energy.
@@kazeshi2
Sapping some of the mass of the sun would also decrease the rate of fusion, counteract the heating of the earth as the sun ages, and would increase the lifespan of the sun.
@@sunnyjim1355 why won’t there be any CO2 in the atmosphere in a billion years?
Only that we're not gonna survive the next thousand years the way we're going on.
"The Mormons were right" fucking sent me lol
You need to apologize to Mitt Romney.
HA I had to replay it just to be sure what I heard!
Where was this? I never saw it...
yeah where was this
@@heliveruscalion9124 he whispered it around the time he talked about planets I believe
I mean. The reason we haven't found any objects or creatures out there in space is that space is huge, and we've barely gone out into it at all with signals and machines. Could be tons out there, we just can't see it yet.
Hey man, i know its been a while and all, things in our lives got crazy.... but i have missed you. And thank you for this good brain get bigger stuffs.
Great channel Joe. You cover almost all of the weird stuff I think about constantly. Keep it up!
Whenever a new unique/weird signal comes in:
Everyone - Must be aliens!
Magnetars and randomly dimming planets: Am i a joke to you?
Addendum...The Hansen Planitarium was the predecessor to what is now a technological improvement known as the Clark Planetarium in SLC UT. It (the Hansen Planetarium) used to present weekly a beautifully adapted starshow based on Asimov's "the Last Question", that being "How do you reverse entropy?"...
Hello Joe, first I want to say I love your videos but I feel I have to mention what I think is a scientific typo at 5:54 watts/sec should be watts or joule/sec. Please correct me if I didn't understand it well :)
Very nice video!
you got an actual "psschut" (lol) out of me with kardashian scale.
Not to be confused with the cardassian scale
Videos like these give me goosebumps every time!
Just the thought of a advanced civilization is encouraging.
I have the exact opposite reaction...
Not sure a Dyson sphere or swarm would be "advanced" as opposed to foolish.
@@mim8312A small swarm makes sense. You don’t need to capture ALL the sun’s energy. A swarm capturing 1% of Sol’s output would also end our energy issues on Earth
I love that joke with the "earth" 🌎
Oh the SHADE thrown at Mercury. That was BRUTAL. 🤣
2120: We've come prepared for this year... Hears that Dyson swarm is now large enough to block enough light from the sun for life to shrivel on... on... Earth!
Thanks so much for the most interesting concepts and ideas in this video. It took me a few minutes to realize you are discussing far future possibilities and necessities. Very interesting.
Again, thank you.
I can't find this "Juice: How Electricity Explains The World" on curiosity stream
Please freeze my brain and wake me up when we're at type VI.
You'd be so outdated though. Like a Abacus in an age of planetary quantum computers.

But that means they'll have the tech to make his brain into an advanced modern one, the problem fixes itself
@@ShadowLynx777 assuming they have technology that's compatible with the current age human physiology. I'm highly doubtful whether humans will be the same creatures they are now by then. we might be the evolutionary equivalent of Darwinius masillae compared to homo sapiens. But hey that's just my pessimistic take on the whole thing. Your opinion is just as valid as mine and speculative as well in terms of accuracy. There is just to many unknowns to assume any outcome of which there are many.
@@HSamee
But you don't get it, if they've mastered spacetime and multiverse convergence, they can easily make an adapter for an ancient brain. Your looking at what they will be, I'm looking at what they can do :)

Nuver great show Joe, thanks but.......
Can't find that curiosity stream doc🙁(yes I have a subscription as suggested by yours truly, thanks ) Is it cos I'm in UK perhaps ?
I love the running gag of checking the paper
There's no need to cover the entire star with swarm. Because orbit is like a disk, you could just capture all the wasted energy, heading out from North and South of the star. You can leave out a stripe in the equator to for planets to get light. You could consume majority of the energy.
This also means the planets can still be used for living, Dyson sphere only for collecting energy.
Too many khan 2-D thinkers, nice to see some 3-D thinkers!
@@mardethkellerman1182 lol
You can't just position collectors north and south of the star. As you said, orbits are disks. Any collector orbiting over the north must cross though the plane of the solar system into the south. With a full swarm there would always be collectors at the equator, even if none were in an equatorial orbit.
Of course, at that level of technology and energy, you could always just have collectors making course corrections to ensure the sun is never obscured from the planets.
@@MinibossMakaque The dynamics are more complicated but you definitely can make orbits which are stable out of the equatorial plane. They would need to be eccentric orbits and would naturally precess but could easily be designed so they never cross the equator.
However if you listen to the video the easiest and most effective solution a statite was already mentioned. A Statite does not orbit instead of using angular momentum to counterbalance gravity like an orbit would a statite cancels out the effects of gravity with radiation pressure instead.
As such a statite would remain fixed in position relative to the Sun at all times. In summary in a true Dyson swarm you can have any configuration of collectors you want because the collectors would not be satellites but *statites*. No pesky orbital interactions or transits to worry about. Both Isaac Artur and Cool Worlds have discussed this in a fairly comprehensive manner though cool worlds missed that the idea he proposed quasites already existed as lagites. (though honestly quasites sounds better)
@@Dragrath1 Oh right, he did mention radiation pressure. That's pretty cool.
I don't understand how you can have orbits that don't cross the equatorial plane though. Do have a resource where I could learn about that?
According to Isaac Arthur : Yes, we could.
Isaac is the man.
They say if brute force isn’t working... you’re not using enough of it.
We can built, but can we solve the radiation and gravity issues.
Well, he'd probably say that we'd go for a Dyson swarm, not a Dyson sphere.

3:53 And Loki shows us a type 6 with the Time Keepers
3:47 - Expects video insert of Q.
3:48 - Oh, yeah, there's him too.
5:53 what's a watt per second? is the power increasing at that rate? Watts per second is Joules per second per second, right?
Yeah that got me too, a lot of educational channels run by laymen use watts as a unit of energy. Makes me question the entire video, to be honest. Fortunately, this is just idle entertainment for me. If I really want to passively imbibe credible information, there's always Veritasium, Steve Mould, Braincraft, Kurzgesagt, etc. etc.
What?
The watt is the most commonly used unit of measure for power. ... A watt equals a joule per second. If a smart phone uses five joules of energy every second, then the power of the phone is five joules per second, or five watts.
@@alekz112 But, you already know about what he actually meant, so why does it really matter? I mean, if that affects your view of the video or creator then you should probably take a better look at those other channels. They've all made mistakes at some point, and most likely used at least one word where they shouldn't have.
@@isaacthecorncob Doesn't really matter, no. Like I said, it's just idle entertainment for me. Chill.
