IAC-2022-Civilizations Through the Eye of Kardashev: An Extended Scaling.pdf

The Kardashev scale is a procedure by which we can detect the advancement in technology and the amount of energy our civilisation is consuming presently from planetary scale. Astrophysicist Nikolai Kardashev suggested that it is possible to distinguish civilisations based on their capability to harness energy from different stages: Type I- from planetary bodies, Type II- from star, Type III- from host galaxy. At present, our human civilisation consumes 17e+12 J/sec energy which places us at 0.72 as per 2015. In order for us to step up to Type I, total energy harnessed by us should be 1e+16 J/sec. Although the difference from 0.72 to 1 seems less, we have to keep in mind that the energy consumption has to increase by 1 million. Literature suggests a gradual hyperexponential curve in this concern. Along with these changes, the civilisation will undergo physical and thermodynamic transformations. There are various biochemical processes that will occur at different ecological trophic levels due to the abundance of complex polymer molecules. When two or more reactions are coupled such that thermodynamically favourable and unfavourable reactions combine, it overall results in a favourable reaction. For each phase transitions occurring, we can thermodynamically calculate temperature, pressure dependencies and other changes that are taking place in the environment at equilibrium. We have aimed to elaborate the energy consumption by a graphical approach, observing the physical, thermodynamic modifications. Detection of different kinds of civilization should be having reinforcement of differential parameters to be incorporated into the conventional kardashev scaling system for deciphering grading, habitability and sustainability of intelligent civilization throughout the cosmos.
