Kardashev Scale

The Kardashev Scale is a hypothetical framework for measuring the technological advancement of civilizations based on their energy consumption. Proposed by Russian astrophysicist Nikolai Kardashev in 1964, the scale classifies civilizations into three primary types:

• Type I: A planetary civilization capable of harnessing and storing all the available energy resources of its home planet. This includes geothermal, hydro, solar, and wind energies. Earth is currently at approximately 0.72 on this scale, as we haven't yet achieved full planetary energy harnessing.
  

• Type II: A stellar civilization that can control the energy of its entire star (like our Sun) and transfer energy from it to its planet. Concepts such as the Dyson Sphere, a hypothetical megastructure that encircles a star to capture its energy, arise from this category.
  

• Type III: A galactic civilization that manages the energy of its entire galaxy. This involves controlling the energy of billions of stars.

The Kardashev Scale is a speculative tool used to contemplate the potential progress of civilizations, understanding their growth in terms of energy consumption, and pondering humanity's future advancements.
