Brain storming

• Beff Jezos: Solving for the Theory of Everything in Fundamental Physics comes down to latent model hyperparameter inference for the laws of physics, where tests of these hyperparameters unfortunately lie beyond our currently observable / testable band of [[energy|energies]]. In order to get answers, we will have to ascend the Kardashev scale. This ascent will unlock perception into this higher energy band. Then we will need the intelligence to understand what we see. Power generation + Artificial Intelligence scaling are the truly [[fundamental]] missions.

Explanation by AI

• The Kardashev scale is a method of measuring a civilization's level of [[technological advancement]] based on the amount of [[energy]] it is able to harness and use[1][2][3][5].

The scale has three main categories[1][3]:

• Type I: Also called a Planetary [[civilization]], it can harness and store all the [[energy]] available on its planet[3][5].
• Type II: Also called a Stellar civilization, it can use and [[control]] energy on the scale of its [[planetary system]], e.g. by building Dyson sphere around stars[1][3].
• Type III: A Galactic civilization that can harness the energy of its entire host [[galaxy]][3][5].
• Type IV: Capable of using energy at the scale of the whole [[universe]].
• Type V: Capable of using energy at the scale of [[multiverse]], manipulating multiverses beyond [[spacetime]].

The scale was originally proposed in 1964 by Soviet astronomer Nikolai Kardashev[1][3]. He used the scale to estimate how detectable hypothetical [[alien]] civilizations would be based on their energy use[1].

[[Carl Sagan]] proposed a more granular version of the scale that uses decimal values, e.g. a Type 1.2 civilization[1][3]. On this version, present-day human civilization ranks at about 0.7[1][3].

While a hypothetical construct, the Kardashev scale puts the energy use of advanced civilizations into perspective and is often referenced in discussions about the search for extraterrestrial intelligence (SETI)[1].
