A theoretical framework for measuring a civilization's level of technological advancement based on the total amount of energy it can harness and utilize. Proposed by Soviet astronomer Nikolai Kardashev in 1964, the original scale had three types: Planetary (Type I), Stellar (Type II), and Galactic (Type III). It’s less about culture or philosophy and more about raw, cosmic-scale power management. The scale is logarithmic; each step represents an increase of energy control by a factor of billions. It's the go-to yardstick for sci-fi world-building and serious SETI research, framing humanity's place in the universe as currently a pathetic Type 0.7.
Kardashev Scale Example: When a sci-fi author says a species is a Kardashev Type II, you instantly know they build Dyson Spheres and use their sun as a personal battery pack. Humanity, still squabbling over fossil fuels and barely tapping planetary geothermal and solar, is still crawling toward Type I, putting our entire history into humbling perspective.
