Rest In Peace to Nikolai Kardashev who sadly passed away to become a Type IV civilization in the beyond on August 3rd 2019. What a wonderful mind, he will be missed.

I was watching this and it cut to an ad. The exact words I heard were "That leaves us with 2 options. Solar energy and - Explosive diarrhea? Upset stomach? Painful indigestion?".... I laughed for like 4 minutes straight.

See you all in 2120 when we are a type 1 civilisation and UKposts algorithm re-unites us all

Something I just now thought of, halfway through this presentation, is that we are also using less energy to do the same things as before. In other words, efficiency. That might throw the numbers off even more.

I always assumed a type 1 lived on multiple planets, type 2 lived on multiple solar systems and type 3 lived on multiple galaxies. I don't see how you can control and consume so much energy on a single planet.

Left the oven on all day. Doing my part!

2020: "In hundred years we'll become a Kardashev Type I Civilization." 2120: *Despacito 420*

Another quality video. Personally, I question Kardashev's assumptions, which I think are rather sci-fi. In time, energy use would ideally become more efficient and the measure of a civilisation's advancement would be ever less based on the energy they use and ever more on the amount of integrated information they process. The animal kingdom provides an example. Empowerment based on size had its limits, with increased information processing turning out to be more potent.

One thing to keep in mind that it is not just about the energy consumption, it's also about controlling the energy and use it in effective and constructive ways.

We should probably focus more on not becoming type "extinct" civilization

I thought I was subscribed to enough science related channels. I was wrong.

With fusion reactions finally having been used to create more energy than what is used in order to create the fusion reaction, it might actually be possible to become a kardashev type I civilization.

You are insane in such an amazing way. Amazing vids mate.

seeing stuff like this makes me depressed knowing I won't live long enough to see this happen, almost like how people in the 1800s can't see how much we've evolved from back then

i'm already type 1 diabetic so i'm type 1 sooner then the rest of you.

Thank you for another great video brother

This Was The Best Video, Very detailed indeed, Instantly Subscribed 👍

*scientists can now turn anger into electricity* Type 4 civilization established overnight. Universe conquered successfully.

So what you’re telling me is that solar energy is just long-distance nuclear energy? 🤔

Love Cool Worlds. you make me want to make content. keep it up. you're inspiring.

Love this channel. Just subed, thank you.

Meanwhile Aliens seeing this video when they hacked UKposts: "These Earthlings can barely maintain a nuclear reactor and they are talking about type 3 civilization." Laughs hysterically in Alien language.

If we can just figure out a way to harness Twitter-fuelled outrage and turn it into energy, we'll easily hit that x1000000 target.

love this channel

24 degrees increase here on earth would not be good but on Mars or any other cold planet would be beneficial

Great video Sir!

02:10 what and why are these constants 7.38 and 9.73 used in the formula ? @CoolWorldsLab

Man now I'm so mad the library of Alexandria was burned.

"becoming a Kardashian type | civilization" Doomed!

Thought-stimulating for sure!

The Kardashev scale originally was meant to describe the power of advanced civilizations, in particular, those that have achieved the ability of space flight. It uses a geometric progression based on the amount of power accessed by the species as it grows. The earliest emerging civilizations don't appear, except as fractional numbers, because their activity is not very significant on a cosmic scale. These only get a full count when they might be noticed by a theoretical "outside observer," as you will soon see. I am adding a few extra levels to the original three, since there was little use for that as a measuring stick to evaluate gradual progress. Let me start near the beginning, when the culture starts to reveal its potential significance. Type One: "Novice" (revised) intensive use of more than half of the planet's habitable surface area for urban dwelling, agricultural production, industry or resource extractive purposes. Oceans, ice caps and deserts are not typically considered habitable, although some oases may exist. Type Two: "Unstable" (revised) threatening the ecological health of the planet by careless practices, whether by stripping resources, excessive pollution, or loss of secondary species. Type Three: "Emergent" (revised) has acquired sufficient technology to make space flight and colonial ventures possible. Potential for mass self-destruction demands a quest for coexistence. Type Four: "Maximized" (original) Type One: intentional use of all the insolation received by the planet for food or power. (revised) has accessed or made feasible all of the resources and energy available on the planet. Approaching a sustainable global regime for shared resources and political consensus or a tolerant balance of powers. Type Five: "Outbreak" (revised) has established self-sufficient populations, with trade routes, in multiple extra-planetary colonies, and continuing to spread. Industrial development of free-floating habitats, space infrastructure and specialized project construction begins. Type Six: "Established" (revised) has explored the entire stellar system in sufficient detail to map a super-majority of its geography and resources. Technological proficiency allows pioneers to colonize the frontiers at will, and choose political independence. Type Seven: "Expansive" (original) Type Two: intentional use of all of the energy output of the star for habitation and industrial purposes. (revised) complete access to all of the resources and energy available within the star system, including its planets, moons, and smaller satellites. Experimental robotic ships explore the nearer neighboring star systems and the conditions of intermediate space. Type Eight: "Arrival" (revised) first colonies established around other star systems. Ultrahigh-energy physics experiments explore the potential for travel at relativistic or supra-lightspeed velocities. Type Nine: "Manifesto" (revised) seeding the stellar neighborhood with many colonial ventures, discovering the range of variety of system formation and geography, and revealing the frequency of the origins of life. Type Ten: "Epitome" (original) Type Three: acquisition and use of the entire energy output of all of the stars in the whole galaxy. (revised) technological capacity to range at will throughout the galaxy, planting colonies, developing resources and tapping unlimited energy as needed to sustain the presence and growth of the species in all its various iterations. Sophisticated modes of long distance travel and self-contained habitat ships allow for sporadic attempts to surpass galactic boundaries. Conclusion: As you can see, the original version of the Kardashev scale assessing the power use of a space-faring civilization was excessively over-simplified. Having only three tiers, it did not allow for any detail or description of the intermediate stages of development. At every stage, it required an "all or nothing" obvious achievement in order to advance to the next rung of the ladder, and totally lacked any descriptive or predictive powers. This revised version does have more capacity for descriptions, and also allows for a certain amount of flexibility. It can be used to note and measure some fractional attainments, and can accept some skipping and mixing of non-linear development patterns, while still offering some definite levels of meaningful achievement for comparisons. Nor does the new scale have to terminate at the edge of the galaxy, or proceed to such degrees as beggar the imagination. At Type Eleven, the colonization of another galaxy, and at Type Twelve, the colonization of the whole local group of galaxies is enough, while further expansion into the greater Super Cluster and beyond may be designated by more numbered levels. These do however go so far beyond the imagination that those technologies would likely appear magical to our sensibilities. And any further would simply involve the acquisition of the entire knowable Universe. It seems probable that, at some point, even before we claim the far reaches of our own galaxy, we are likely to discover another intelligent, civilized and space-faring species and learn not only whether the scale is truly useful, but have the realization that we must share the Cosmos with our neighbors. And that will be a clear answer to one of the oldest questions we have ever thought to ask. If you wish to adopt and promote this revised scale for the comparison of developing civilizations and space-faring technology, you may be my guest. I ask only that you acknowledge and attribute it to its source, and name it the "Makarios Scale." Makarios means "Blessed" in greek, and any species and civilization that this scale would measure should be well aware of their blessings. And I thank you for your patience and kind consideration. Shalom. I published this in September 2020, in my own obscure little blog: www.emunahechad.blogspot.com

When he said nuclear energy I got an ad for HBO's Chernobyl lol

When Kardashev came up with the scale I believe it was his intent to account for efficiency and different stars. it was just an order of magnitude he was going for. A K1 civilization has reached the limit of what they can get without leaving their planet. A K2 civilization has reached the limit they can get without leaving their star. A K3 civilization has reached the limit without leaving their galaxy. Firstly, does it matter much if your solar panels are 50% efficient or 100% efficient? By Sagan's formula if we gathered only half the energy striking our planet we would be K0.97. That's a K1 as far as I'm concerned. Secondly, not all planets, stars and galaxies are equal. A civilization on Europa could reach K1 from tidal heating alone, because tidal heating is orders of magnitude greater than insolation on that moon. A K2 around Proxima Centauri would only be a K1.72 by Sagan's formula, because Proxima Centauri has only 0.17% the output of Sol. Using rough estimates of OUR planet, OUR Sun, and OUR galaxy to judge other civilizations that exist elsewhere is hubris.

Option 3: We find a way to siphon off more heat into space. If we are suppose to control the weather as a type 1 civilization (in the original), that means we should be able to control the temperature anyway. option 4: We manipulate the atmosphere so that it becomes more reflexive (maybe just for certain wavelengths) Option 5: We find a way to transfer heat (ideally to a planet that needs heating for terraforming) by some special form of artificial wormhole.

If we consider basking in the sun, growing plants for food and keeping the wildlife as things we want, this should also be considered as consuming the energy from the sun. A bit hard to calculate the amount of energy for this, I know.

The World currently: when you wanted to become a Kardashev Type 1 civilization, but you only had money to be a Kardashian Type 1 civilization lol

Sounds to me that type 1 is interplanetary, type 2 is interstellar, and type 3 is intergalactic.

Thank you for your insight and also It is gentle of you to speak clearly and slowly little bit compare to other youtuber that we can understand better because english is not my first language. thanks.

This professor makes complex science understandable for armchair science fans like myself. I was terrible at math and physics in my youth, but I loved the theoretical aspects of science. Especially geology and paleontology. Keep teaching well prof. We need the link to improve our collective intelligence so everyone can comprehend the dire situation our species faces before the political idiots run us over the cliff. Rock Onward Intelligently!

Linguistically, Kardashev and Kardashian is the same surname, with Russian and Armenian genitive case endings respectively.

Being level one civilization doesn't mean that we should consume that amount of energy on our home planet itself. It simply means the consumption of energy by that civilisation... Be it a factory base seated on its moons or asteroid belts or some artificial space structure.

Good Stuff Boss Thanks 🙏

Hey Professor David, just wanted to say that I love the music from Thomas Bergersen you used at the end of your video.....just a little sidenote....this video was so fascinating though!!!

We’d never reach type I with the current education system

This, is a type 1 civilization... And this.. *builds sun powered super weapon* Is to go even further beyond!

Great channel 👍

What an excellent overview! @Cool Worlds Do you mind if I ask what is Cool Worlds' source for mankind's 2017 power consumption of 1.7 x 10^17 watts? And where can the latest figure be found? Many thanks!

Sir, it is such a pleasure to listen to a well presented notation of an intelligent person.!

I love the artist depictions of advanced societies

I'd say: Colonize a frozen world, absorb/use the solar power efficiently, have the dissipated heat make the planet more habitable.

Great thoughts

Great talk👍❗️

We need to make more energy, my lifes purpose is now clear.

Earths civilisation may not be type 1 civilisation, but we are pretty much type 1 diabetic

thanks for the formula for T-eq. I always wondered how they figured out whether an exoplanet was warm-terran or not

The main thing this discussion is missing is that the temperature difference (via albedo adjustment) is that that's the temperature of the shell itself AND the perfect absorber is also a perfect transmitter (Kirchov's Law) not only would be have a comparatively cool underside to the collection medium, but a lot of that thermal energy would be transmitted back out into space when it was on the night side. So assuming your math is correct we'd be looking at only half that as a starting point (nominally) as only half the planet would be absorbing at a time and the other would be emitting. Not to mention that a lot of that thermal energy would naturally be converted to energy that was used elsewhere, like the moon, (through chemical production/propellants/batteries/lasers/whatever). Yes, it would be a challenge, but merely an engineering challenge of large scale, which, if we got to the point of having 100% solar encapsulation, it's fairly safe to assume we're prepared for the undertaking of large scale engineering problems.

A physicist once said: when kids look up to great scientists the way they do to great musicians and actors, civilization will jump to the next level. Until then no amount of energy is taking us to be type 1.

Unfortunatelly we are mostly becoming a Type I Kardashian Civilization :(

I've always tried to imagine what higher level civilizations would be like. The theoretical type omega civilization for example would use an entire universe. From the perspective of us they would be basically gods. And I don't mean that lightly, they would literally be gods by any definition. If such a civilization exists they could have actually created our universe as a power source and could have done so multiple times. The capabilities of such a society (if you could even call them that at that point) would be truly unfathomable.

Thank you

I would definitely argue that a Type I would necessitate the civilization be multi-planetary. But Kardashev's quantification of the classification requiring 100% consumption of local stellar energy directed at a planet is extremely variable, as if we think about it while assuming extraterrestrial non-human civilizations exist then applying this rule to a civilization which may have developed around a lower output star lowers the bar considerably for them, not to mention if the civilization inhabits a planet with a significantly different atmospheric composition. So Kardashev's criteria is a good starting point, but I would think needs to be refined, or at least thought of differently. A multi-planetary Type I civilization maybe need consume 100% of planetary stellar radiation reception for their planet of origin but utilized across their entire civilization? This fits still within the rule, as a multi-planetary Type I which consumes 100% of stellar radiation on each individual planet has a total consumption greater than 100% of a single planet's reception, pushing it beyond a Type I and well on its way to a Type II.

I swear I read “Kardashian” and not Kardashev. Obviously the former is from a negative-5-type civilization.

Your active support structures could act as giant heat exchangers. In fact I believe you could use glycol as an active support substance if you really wanted.

Phew, that was a close one. Reading the title and not having heard of the name Kardashev before, I first thought it was a fancy new term for Kardashian.

Humanity shall become star bound as long as we don’t destroy ourselves.

Potentials by Maximum Extraction Wind/Wave - 1800 TW [6:43] Tidal - 3.7 TW [7:15] Geothermal - 47 TW [7:30] Nuclear - 5x10^28 Joules [9:25] Solar - a Dyson Sphere [10:14] Blackhole - let’s ask CERN?

2 takeaways: 1) Yes, in my mind, it wouldn't make sense that a Type1 would not be multiplanetary, on one side you have all the issues you mentioned, on the other there's the case of what would we use that energy for if we aren't even ferrying cargo across planets. It looks like we might be mutiplanetary in the next 100y. Not as likely to be type I before that. And the logic would go for a type2, surelly they would have multiple star systems at their disposal rather then completely harvesting a single star. Very risky to experiment in a planet/star if it's the only one you have. 2) We would probably want to recycle our energy. As you said, the energy isn't wasted it's converted into kinetic energy. Rather then build a giant fan to cool it down, build a giant "fan" (read, wind turbines) to harvest that warmth (and cool it back down as a biproduct) Imagine the following experiment: a 1m cube in vaccum. at the bottom there is a computer, and as it uses energy it warms the air around it, causing the now warm air to flow upwards and the cool air to flow downwards. Now place 2 wind turbines that capture the energy of said air moving both upwards and downwards. The process of using electricity by the computer provides an opportunity to harvest more power. Not claiming that you will get a 100% recyclable system, but if you could recycle 50% of the consumed power, that would mean that every 1 watt of power harvested from the sun would produce 2 watts of power before being released back into the planet. With a 90% recycle rate it would give us an entire order of magnitude: 1 watt harvested = 10 watts used before it leaves the planet's control

Great video. I had an Instant idea the very moment you talked about the heat problem of a solar covered palet Type I civ.: SPACE RADIATORS!!! Imagine we could build something like a giant Radiator that takes the unwanted heatwaste, and dissipates it into space. Like the Radiators onboard the ISS but on a Planetary scale. They would cool the atmosphere, not mere buildings. I imagine a Type I civ. would be able to figure this out, if they´re able to build megastructures like planetcovering solarpanels.

I’ve never wanted a video not to end so much in my life

I haven't smoked weed in 3 years, Just watching your channel for 3 minute I was craving for a joint.

By the time you can utilize that much energy, you can #1 minimize heat loss #2 use excess heat to generate energy #3 build massive heat pumps around industrial complexes to collect heat for #2

May be: If we add an additional scale "efficiency" of using the energy, than from some point the growth in efficiency will pick up compensating the decline in consumption of energy, due to various reasons like, not having technical capabilities in this particular direction or having another targets, like - not increasing the temperature and ultimately reaching the same point of controlling the same amount of energy. There is another possibility as well like increasing the communication and logistics technology that allow to spread one civilisation less dense in more space that can also increase the amount of controlled amount of energy by one civilisation. May be with more controlled energy our self-perception and our targets will change and will be not measured any more by energy consumption. But today are :) I think as well that speed of consumption of energy plays the role and it is interesting how it effects the dynamics of controlling the energy.

Nikolai was always my favourite Kardashian.

Stellaris players: *Heavy breathing intensifies*

Ngl I found the thumbnail mad interesting when I initially misread the title as “Becoming a Kardashian”

Hello, thank you for the great video. What about this option. 1. Launch satellites that orbit the sun. 2. These satellites will use the solar and heat, maybe even the star's fussion. 3. This energy would be stored on huge batteries onboard the satelite. 4. Once batteries are at capacity, the satelite either: 5. a) Travels back to earth to deliver the energy. 5. b) Transmits the energy back to earth either via radio waves (simmilar to Nikola Tesla's methode of transmitting electricity via antenna) or 5. c) Transmit energy to earth via laser beam. Of course energy captured from sun has to be greater than energy used to deliver satellite to and from orbit. Once again thank you, and sorry in advance if the question is silly.

You're smart and a good teacher, subscribed

I hereby identify as a member of a Kardashev type I Civilization... and on a side note Kardashev got autocorrected to Kardashian 🤦‍♂️. We got a long way to go.

I have concluded long ago,that the only way to become a type 1 civilization, is to mostly move off the planets and use smaller bodies, like asteroids, for resources. You can't get rid of the energy problem just by having many planets. Some of them planets then have to grow food, and some are better suited than others. So no matter what way you look at it, you're growing food in locations not originally suited to the food sources, so it might as well be in space.

The waste heat is more usable energy, just in a different form. We just need an efficient way to concentrate, transform and/or transport it. If we discover an efficient enough thermo-electric effect that energy can go into food production, supplying base load power or in materials production, free industrial furnaces for all, and the conservation of energy is maintained. Also if you have a global structure that is only being heated by 47TW's/ large sections of it will probably need active heating anyway.

Man, I completely forget about accounting for the heat energy that would effect the atmosphere by becoming more energy efficient. It seems like colonizing other planets and moons makes more sense than trying to stay on Earth. Awesome video!

I thought this video was new until 15:42 This video is timeless

While watching the video I got to the part of you talking about the conservation of energy and how the planet would heat up if we we're to take on all the energy needed to be a type I civ. Then I paused it and went on 20 minute rant to myself about not needing to be single planetary and sending energy to the moon and mars would still make us type I. The benefit being we need to heat them anyway, and the moon already has no atmosphere, so excess could just be vented.

WIND MILLS..... ON JUPITER!!!

12:35 "A very basic calculation we give our students in intro level classes" 12:40 Slowly packs up textbooks, applies for job at coffee shop.

I would say an easy way around the heating issue is to make the species multiplanetary and distribute the power consumption between the different civilizations within the solar system.

Could you produce more energy than needed to be a type 1 civ off planet or on another planet while transmitting that energy (assuming for loss) to the habitable planet?

I would say that it is a safe assumption that any civilization that approaches type 1 would also posses the ability to freely travel through its own solar system, and settle the various bodies there.

Arthur C Clarcke talked about some space radiators to get rid of the excess heat in 3001: Final Odyssey. But logically, I think a Type 1 civilization cannot happen if it stays ground-based. It must become mostly a space civilization. We talk here about a civilization that could live mostly in a ring aroung the planet in geostationnary distance using space elevators. The Ground would be mostly for wildlife and agriculture.

Cold fusion!

Woow, good videos)

Damn...totally missed this channel...immediately subbed, great quality!!

Thought this said kardashian type one civilisation I need more sleep

Are we limited to being capped at reaching a maximum of around the .65 on the type 1 civ scale, does that take into affect how much energy is possible to harness within our sun's limits? Surely we must be capped by what's available for us to consume in terms of energy. Given if we are only able to use our own sun's power, would we have a higher score if we had a different sun?

is there any way to harness the solar energy already being produced and converted by plants?

Love the video, just subscribed to this channel and looking forward to going through your play list.

Might I suggest The Culture novels, written by Iain M. Banks? The Culture is a great example of a Type 3 civilization. An actual utopia.

Much like the running gag about fusion always being 40 years away, we always seem to be about 50-100 years away from running out of oil.

Best hope for the future would be to go the other way, and work out how to get by reducing the amount of energy you need by becoming far more efficient.

Not only is your content exceptional, you are as pleasant to listen to as Mr.Sagan. TY so much!!
