The kardashev scale is bullshit.

We've never seen evidence of intelligence in your brain anywhere either, and you're probably around 20 years old. If there was any there, we'd see it in your posts. Furthermore smartposts are the easiest to see since most of /sci/ is shitposting, and we haven't seen one.

>believing the kardashians
wtf

>>8973117
donk

>>8973105
It's an arbitrary scale, how can it be bullshit?
It's not claiming that any of these civilisation actually exist, it's just a way of classifying them if they did.

>>8973105
>humans might reach type 3 in a few hundred thousand to a million years

about as optimistic as you can get

What makes you think you'd be able to perceive a type 2 unless they wanted you to, much less a type 3? If they're out there, keeping a low profile is going to be important, lest you attract the attention of someone else as or more powerful.

>>8973105
We arent even type 1 and we can already create nanomaterial, wouldnt a type 2 civilization be operating on planck physics?

Most advanced aliens in our reality probably dont use EM radiation as a way to communicate because its primitive from their point of view, instead they use something we have to discover.

>>8973105
The star within a solar system is 99% of it's mass so how the fuck can you use the resources within said system to enclose the star?

>>8973105
We haven't even examined 1% of the observable universe, let alone the 'whole' universe.
There is no way you can say with 100% certainty that we're the only living, or intelligent beings in the entire universe.
Considering the amount of Earth-like planets and planets in the Goldilocks zone and the possibility of unusual xenobiology, I think it is highly likely there are other living and intelligent beings in the universe.
Considering the size of it and the complexity of travel within it, it isn't too much of a shocker that we haven't found anyting else yet. Though we might.
Making platitudinal and ignorant statements, showing the arrogance within, is pointless.
We may, or may not find life, that doesn't mean we shouldn't consider the implications and possibilities.
Also, to close, I didn't know /sci/ stocked so many armchair Nostradamuses.

>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.

>>8973105
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.

>>8973506
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

>>8973105
>muh sci-fi civilization scaler is rubbish

Complain about it on >>>/x/, 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?

>>8973117
Kek

>>8974405
wrong question, how do you even know there is a space to travel through?

>>8973227
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?

>>8973105
>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.

>>8973105
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.

>>8977501

>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.

>>8977501
Attila pls f/go and stay go

>>8973105
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.

>>8977916
A sentient planet automatically reaches type 2.
It could, for all intents and purposes, have the intellect of a 2 year old.

>>8973105
>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.

>>8977919
There's no rule that civilizations are bound to reach any level or progress to another once reaching one.

>>8977926
There's no rule saying that there will be any useful rules or scales that could measure them
YET HERE WE ARE

>>8977916
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.

>>8973453

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

>>8973453
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

>>8977939
>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.

>>8977943
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.

>>8973484
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.

>>8977972
If you're mining the star why bother to enclose it?

>>8977975
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

>>8977501
>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.

>>8978504
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

>>8979068
No, white dwarfs for example consume relatively low amounts of Hydrogen.

>>8979068
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

>>8979500
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.

>>8979511
white dwarves don't make energy stupid

>>8979516
also wind and all available fuels

>>8979516
and how the fuck is anything supposed to live with no solar or geothermal energy retard?

>>8979523
are you fucking high?

>>8973105
>There are no dyson sphere signatures and there are no galactic structures either.

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

>>8973105
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.

>>8979517
Lol you are stupid. they have nuclear fusion going on inside them. That is why they emit white light.

>>8979538
>>8979529
>>>/trash/

>>8979523
I believe it is about the ability to battery/utilize this energy at will, not immediately consume it all.

>>8979538
White dwarfs radiate thermal energy but are out of fuel. They're just a ball of electrons.

>>8979531
I think we already have an explanation for the tabis phenomenon

>>8980286
what is it?

>>8980381
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
