Kardashev Table - Types and Civilization

According to this theory, the more a civilization grows and develops, the greater its energy needs will be due to the disproportionate growth of its population and the energy needs of its machines. The Kardashev scale was developed based on the idea that a civilization could consume more energy based on its technological advancement.

The scale was developed in 1964 by Nikolai Kardashev, a Russian astrophysicist researching extraterrestrial life. It has three classes, each with a different energy level: Class I (10¹⁶W), Class II (10²⁶W), and Class III (10³⁶W). Subsequent astronomers expanded the number of these classes, including Class IV (10¹⁶W) and Class V. The Class V energy level encompasses all possible energy found in all universes across all timescales. This unit of energy also determines the level of knowledge of civilization.

First of all, we, humans, haven't yet reached this level. Our current level is Class 0. We have a very long way to go to reach Class I. According to renowned physicist Michio Kaku, we have 100-200 years to reach this level. But what about the other classes?

Class I energy means being able to utilize all available energy within the habitable zone and store it to meet the needs of a growing population. If we want to reach this level, we need to increase our current energy production by 100,000 times. To achieve this level of energy production, we need to be able to harvest all the energy in the world. Humanity could theoretically use volcanoes, weather events, and even earthquakes to generate energy. While it may be hard to believe, with developing technology, managing all energy possibilities is simply a matter of control.

The amount of energy at Class II level is the ability to use all the energy of the star in the star system (using the star's energy in a controlled manner, not taking the star and converting it into energy as it is). There is a suggestion for this – Dyson Sphere (Another article on the subject connectionThis device occupies every inch of the star and transfers most of the star's energy to its associated planet. If this civilization truly masters fusion (the star's energy source), it could establish a facility near a gas giant planet to meet its needs and generate energy. It would gradually consume the gas giant.

What could such energy be used for? It's actually unknown. What this class of civilization could do is only speculative. For example, changing the Earth's orbit in case of a meteor strike. Let's say we didn't relocate the Earth, then it could also be used to relocate planets like Jupiter. Isn't that cool? :)

Yes, we can now use our planet, even our star, as an energy source, and we are doing many things for the survival of our species. Now, Class III is here. Class III represents a world-class civilization capable of galactic flight and possessing the knowledge of everything that can be done with the energy it possesses. If we extrapolate from hundreds of thousands of years of human evolution, and add to this the advancements in technology and knowledge, it's certain that the human race that reaches this level will not be the same as the current human race. This race will have many features, such as cyborgs and cybernetic organs, and a social structure that will be different. It will also have fully utilized the advantages of genetic engineering. We can even speak of a social structure where completely natural biological humans are despised, belittled, and belittled.

At this point, the human race will have produced robots capable of self-regeneration, and after colonizing each star system, their numbers will have reached millions, spreading throughout all systems, and perhaps even produced robots of the past. The energy of all these colonized star systems can be concentrated in one place with a Dyson sphere and used for immense purposes. Of course, this brings with it a few problems. Unless we break the laws of physics and exceed the speed of light—like warp technology or a wormhole—we may struggle to harness this energy.

Class IV, on the other hand, is considered unlikely. This class would require the ability to store all possible energies in the universe, including black holes. A civilization that has reached this level would be capable of anything, even breaking the laws of physics by living within the event horizon of a black hole.

Class V. This class is completely at a level that rivals the concept of God. Being able to store all the energy of all times in all possible universes might even make the concept of God a reality in this civilization. But such a possibility seems highly unlikely.
