You have to return.

i've been here when moot used to post. Fuck off. kurz videos used to get posted all the time around here - just because they got popular with the crispr video doesn't mean they are """""reddit""""", anyway there's nothing wrong with browsing reddit - that's unironically a meme made in 2015

>>11963510

Kurzgesagt is 100% NPC normalfag content.

Kardashev scale is not real science.

>>11963519
yet most normos don't know about the shit they talk about. anyway if they accurately talk about the subject while making it easy to understand, whats the issue?

>kurzgesagt
nope, you have to go back

>Kardashev scale

I never really got the point of this meme-measurement. Saying that humanity is 0,75 on this scale might sound "scientific" but literally means nothing.

>>11963568
This
Why are we on the 0.75 anyways?

>>11963571
>Why are we on the 0.75 anyways?
Kardashev scale is not real science.

Reminder than a real scientist can write and thing about things that aren't real science, aren't real philosophy, aren't real anything other than fiction fantasy sci fi shit.

>>11963568
Humans arent even close to harnessing all the energy in the atmosphere let alone the core we aint remotely close to a Type 1

another bullshit scale made by people that don't know jack shit about thermodynamics. people just look at the energy mass equation and think that there is a ton of unharnessed energy but they forget that almost all atoms and matter are in a state of equilibrium and in order to get energy out of it you will need to use a huge amount of energy that is probably more than what you are going to . this applies really for all energy in the universe.

>>11963442
This video really feels like a rehash of an older video, except dragged out over 10 mins and doesn't really question it beyond out ruling the possibility of a type 3 or beyond civilization existing.

>>11963442
I’m not sure why people always talk about Dyson spheres being THE thing and the next step. Building giant megastructures seems pretty retarded to me. I don’t see why you need so much energy to expand across the universe. Seems like we can easily expand across the galaxy with fusion energy alone without a big stupid structure.

>>11964046
How would one build a dyson sphere? What material would be used?

>>11964046
>dude so you know how stars are huge and make shit ton energy with fusion? what if we like take it lmao

>>11964055
Other mining planets I’m guessing.

>>11964062
No I mean name the specific metals and materials that would be used, explain how they can be used (why they wouldn't be destroyed by the star), and how would you make it such that you can build the shell around the star so that it stays orbiting around the star and they never crash into each other.

>>11964010
wouldn't it be better at that point to extinguish stars and collect the contents?

>>11963571
The scale is random shit some asshole came up with to use all the energy of a planet, star, galaxy and so on.

It makes assumptions like building a Dyson sphere. Which is retarded, because any alien that could build a Dyson sphere would only build one as an art project and not for energy.

>>11963442
kurgesagt is for 16yo

>>11964068
Isaac Arthur is a less 16Yo content and explains that we could build habitats until we use all the star's energy, more like a fog than a sphere tho

>>11966101

why so?

this might help (you)

>>11966782
kek

>>11966756
You didn't answer the question. Are you saying this Isaac Arthur guy actually lists off specific materials and engineering parameters that can be used to build a dyson sphere? Can I get a link?

>>11964046
sphere is a meme at best we will build swarm capturing fraction of suns output
>why
its literally free energy and fusion might have its limitations

>>11963442
Kurzgesagt used to be good, but frankly they're pushing their agenda too much lately.

>>11966911
>Are you saying this Isaac Arthur guy actually lists off specific materials and engineering parameters that can be used to build a dyson sphere
i think he has a video about Dyson spheres but idrc , just look up SFIA on Youtube, might not be as detailed as you would want tho

>>11964068
It's not a solid shell it's trillions of habitats and solar collectors in orbit. You don't need anything magical just pretty much any metals.
Why would they be destroyed by the sun? We aren't being destroyed by the sun and neither is Mercury. Like wat?

>>11966944
I found it. It's what I thought it would be. A guy just spewing generalized nonsense about bullshit and just magically assuming other people will figure the stuff out for him. He has a B.S. and physics and thinks this grants him an authoritative position.

Reminder that back midway through last century scientists genuinely believed with the same confidence that modern futurists have that we'd have robots and moon colonies and flying cars and von neumann probes would permeate the star system and we would be able to download information in our head and do all that stuff before the year 2000. It didn't happen then, and it isn't gonna happen now.

>>11966949
>You don't need anything magical just pretty much any metals.
False
>Why would they be destroyed by the sun?
Shit gets destroyed by the sun if it's not tough enough, not large enough, and too close. We would need a special metal that wouldn't be incinerated by the star while still being close enough to take in the energy. We don't have any such material now.
>We aren't being destroyed by the sun and neither is Mercury. Like wat?
What the fuck is this statement. Do you have any understanding of how this shit works?

>>11966967
ok then

>>11966972
Not sure if trolling or just this stupid

>>11966972
>while still being close enough to take in the energy
?????
we can literally "take in" energy from sun with solar panels on earth why do you assume it has to be so close?

>>11966943
>they're pushing their agenda too much lately.
which one

>>11963442
A scale that tells you how much of a cancer your horrible species is. Varies along with the probability the reapers will awaken and cleanse the galaxy

>>11964010
Yeah I hate these "scales". Just because you put a bunch of nonsense meme-ideas on a "scale", doesn't mean any of that shit actually exists.

>>11963442
this isn't even a new topic for them.
fuck off with your popsci fagary

>>11966980
I'm smarter than you
>>11966993
That's what a dyson sphere is. What you're saying is that dyson spheres arent possible

>>11963442
The most central and irrational faith among people is the faith in technology and economical growth. Its priests believe until their death that material prosperity bring enjoyment and happiness – even though all the proofs in history have shown that only lack and attempt cause a life worth living, that the material prosperity doesn’t bring anything else than despair. These priests believe in technology still when they choke in their gas masks.

>>11966967
I have a feeling that you're on the spectrum.

>>11963863
>pop-sci apologists should be executed
You sound like Jimmy Neutron

>>11963682
The mind field stuff along with most of his older videos were decent. Scishit is cancer and just as bad if not worse than basedzesagt imo

>>11966846

>That's what a dyson sphere is. What you're saying is that dyson spheres arent possible
is it really? see pic related
seriously do you even read shit before you reply? this post >>11966949 you were replying to in >>11966972 says
>It's not a solid shell it's trillions of habitats and solar collectors in orbit.
so that post was clearly talking about swarm not solid sphere, anons earlier in thread told you its not solid sphere and even that stupid video in OP was talking about swarm
nobody in this thread except you was talking about solid sphere

>>11969103
cool thanks

This is a nice thread

I think kurzgesagt is pretty good, of course its not a college lecture in science, but it can give you stuff to think about while making it really pretty to look at with outstanding animation, sound desing, writing, etc. Its pretty much entertaiment, but that doesnt mean its inherently bad.

WOAH I FREAKING LOVE SCIENCE

aliens aren't real because space doesn't exist.

>>11971319
This.

>this garbage board have threads dedicated to reddit pop-sci channels

Meanwhile no one makes a thread when our guy Eugene posts a new video

Why don't you come here, anon. I will make science fun for you.

fuck off shill

What's it even for anyways? Can anybody educate me on it?

>>11963510
see pic

How many (((NGOs))) is this guy sponsored by?

>>11972057
One of their videos is just an animation of Steven Pinker's politics so it's easy to take guesses beyond the Gates Foundation.

>>11971837
it's an easy way to describe different civilizations in your favorite scifi series

>>11973667
Was that the "optimistic nihilism" video?

>>11971517
Pop sci is not real science. If you require pop sci shit to find science interesting, you are not worthy to be a scientist.

>>11973753
I don't remember that one well, but I was referring to the "Is War Over?" video.

How many fps can I achieve on Fortnite on ultra settings at 4k resolution if I harness all of the sun's energy output? Please keep in mind that I intend on using a black hole to cool down my graphics card.

>>11976348
This. Unironically a good science channel. I would also recommend the Event Horizon podcast, as well as Anton Petrov's channel.

>>11973788
Physics (that goes beyond everyday phenomena) does not qualify as science anymore. There are an increasing number of theories that simply aren't testable and falsifiable and also even the notion that the laws of physics are consistent in time and in space is not a given anymore either.
