Video - Journey Through the Kardashev Scale: From Wood Fires to Galactic Creators

Kardashev Scale, An astronomer named Nikola Kardashev formulated a scale and divided the civilizations into 8 levels. Each level was based on the amount of energy they produce per second. Spoiler: Level 7 civilization is of creators. Level 0 Civilization- They completely depend on natural resources like wood, fossil fuels to generate energy. Currently we are at 0.72 level on Kardashev scale, and will require 100 to 200 hundred years to reach level 1. Level 1 Civilization- They will shift from natural resources towards nuclear energy. They will be able to create energy through nuclear fusion, which will help to create nuclear space crafts. Like this video to know more about civilizations.
