The kardashev scale is bullshit

>It's an arbitrary scale, how can it be bullshit?
Not OP, but...
It implies that more advanced civilizations have a higher population and/or less efficient use of energy.
Both those ideas seem backwards to me.

I'm pretty sure it's just a science fiction term no different from the power levels they give dbz characters.

Nobody but flat-earthers believes in FTL anymore.

More advanced civilizations do have more population, as more people means more specialist researchers
and it does not at all imply less efficient use of energy, it revolves around increased access to energy

>muh sci-fi civilization scaler is rubbish

Complain about it on kid.

Serious question from a pleb;

If we are not in the "center" of the universe and we are only able to see ~14 billion light years, how do we know there aren't civilizations beyond what we're able to observe. Barring that, have we actually been able to observe anything other than radiation from distant galaxies? According to OP, we know of every single planet in the entire universe and have studied it in detail, how do we accomplish this for stars that are 13 billion light years away?

Kek

wrong question, how do you even know there is a space to travel through?

this, we could make a new one right now. it doesn't mean anything.

Water is level. The size of the container doesnt matter. Earth is mostly water, and water is level, so earth is a level plane. Because it must be...right?

>The kardashev scale is bullshit.

It's basically an arbitrary scale.

You could equally measure civilizations by the amount of electron volts they can capture.

the scale is bullshit, because it's based on egocentric worldview, that assumes all sentient life behaves like energy hungry super virus, when our sample size is literally one, and we are hardly a shining example of what an advanced civilization should look like.

>the scale is bullshit, because it's based on egocentric worldview, that assumes all sentient life behaves like energy hungry super virus

You need energy to power life, and dedicating more energy to your life gives you more chance of reproducing.

It's practically necessary for successful life forms to behave/evolve this way, to the extent that they can find the energy to support it.

Attila pls f/go and stay go

Arbitary but not bullshit. The fact of the matter is it takes energy to survive and more energy = more survival. Type 3 was a good stopping point because harnessing the energy of the universe or beyond is essentially just religion again.

A sentient planet automatically reaches type 2.
It could, for all intents and purposes, have the intellect of a 2 year old.

>some sci-fi writer says LOL PLANET, LOL STAR, LOL GALAXY
There is no reason to assume anything that Kardashev said is valid or notable. They are simple musings of a person who likes sci-fi.

There's no rule that civilizations are bound to reach any level or progress to another once reaching one.

There's no rule saying that there will be any useful rules or scales that could measure them
YET HERE WE ARE

Type 1 just assume some level of planetary colonization that implies control (aka weather machines) not that any planet would need a weather machine, making the Type 1 classification meaningless. At best it is an arbitrary way of saying "yeah we rule the planet"

Type 2 is assuming either a dyson sphere (dumbest possible idea of all dyson's ideas) or solar mining for matter. Which either means you're simply skimming for hydrogen that is just as easy to get from a gas giant or you're eating the entire star to transmute into other materials through an artificial supernova.

Now would a Type 2 eat stars before or after they colonized multiple solar systems? I'd hope after.

Type 3 eats an entire galaxy of stars and more, for whatever purpose, I guess to build more artificial space stations and spaceships for whatever purpose the civ thinks it needs.

Type 3 is stupid because it uses the same technology as Type 2 (mining stars for resources) it is just a Type 2 where you do it a few million times more.

Its so fucking stupid with the giant leap between Type 1 and Type 2 and that Type 2 and Type 3 are literally the same.

It's kind of hard to hide a days on sphere.

we can detect the energy emitted by stars
if a star is there, but emits a lot of infrared, and fuckall anything else, we'd be able to detect them

>type 2-3 civ fires supernova weapon at star
>SPLATDOOSH!
>ooh supernova, pretty
>vacuums up the star and mines the white dwarf for metal
>scientists wonder why they don't see any supernova remanants from a supernova that happened 50+ years go

or

>star goes dark
>not there anymore
>that's weird
And that's if we're lucky that it is close enough to notice and we were looking both before and after.

Signals attenuate over long distances into worthless static so unless its fucking close there's nothing we'd even be able to see with an ideal telescope.

Why are you assuming they're building a dyson sphere that emits infared?

Why would a type 2 or 3 civilization even want to build a dyson sphere? I'm sure they have a better use for their time and resources.

The lithosphere of a planet is, like, 1% of the mass of the planet. How does it surround the rest of the planet?

Also: Mine the material from your star. There's about 500 Earths worth of metals in the Sun.

If you're mining the star why bother to enclose it?

because the shit you are lifting from the star is helium and heavier, which is poison for the star

if you suck out that, and dump new hydrogen in, you could keep a star going forever

>our sample size is literally one
>we are hardly a shining example of what an advanced civilization should look like.
Way to completely undermine yourself in a single sentence.

First, there is no such thing as "poison" for a star. That's pop science
Second, you would need ridiculous amounts of hydrogen to keep a star going

>use all resources on homeworld
>homeworld is now a lifeless rock
I seriously hope we don't do this

No, white dwarfs for example consume relatively low amounts of Hydrogen.

also ridiculous amounts of energy and martial to build and operate such a structure, probably more than could be harnessed from the start over it's lifespan

They mean converting all available geothermal heat, sunlight that hits the surface and probably shit like tides and falling water all into electricity, not mining out the core you fucking twat.

white dwarves don't make energy stupid

also wind and all available fuels

and how the fuck is anything supposed to live with no solar or geothermal energy retard?

are you fucking high?

>There are no dyson sphere signatures and there are no galactic structures either.

yes, everybody, except for the faggots on /x/, already know this.

We actually see evidence of dyson spheres. Tabis star may be one. Plus, if you have fusion energy, then you dont need to harvest whole suns.

It is easier to create an actual sun than to build a sphere around it. So K1 civilisations will likely stay K1 until they reach the exponential explosion point of spreading. My point is that in a causally isolated universe, there is probably only 1 >= K2 covilisation, because it expanded so fast that other civilisations were terminated.

So we will be the first such civilisation :) Im really looking forward to this.

Lol you are stupid. they have nuclear fusion going on inside them. That is why they emit white light.

...

I believe it is about the ability to battery/utilize this energy at will, not immediately consume it all.

White dwarfs radiate thermal energy but are out of fuel. They're just a ball of electrons.

I think we already have an explanation for the tabis phenomenon

what is it?

I think there is a huge asteroid belt around the star
Not sure though

reminder that Spheres are impossible, but SWARMS are not, and are ridiculously easy to make, what with them being just a fuckton of individual habitats and collectors in a foggy cloud around the star

you don't need to go make the whole thing in a day, you just make a single habitat, and then another, and another, gradually until you get your swarm
