However, the Kardashev scale was not developed to model a specific civilization.

Many extensions and modifications to the Kardashev scale have been proposed.

The 'Kardashev scale' is a method of measuring a civilization level of technology advancement.

The Kardashev scale, a scale measuring the technological growth of civilization, named after him.

Thus the Kardashev scale may not be relevant or useful for classifying extraterrestrial civilizations.

Kardashev scale for technological advance in physics.

Type II civilization, an advanced civilization on the Kardashev scale.

The Forerunners are a type-two civilisation on the Kardashev scale; they can build artificial planets and control stars.

The creation of such a system would make its builders a Type-II civilization on the Kardashev scale.

The Kardashev scale classifies civilizations based on their level of technological advancement, specifically measured by the amount of energy a civilization is able to harness.

This theory is similar to Russian astronomer Nikolai Kardashev's later theory of the Kardashev scale.

Their abilities in the series far exceed that of a Type III Civilization on the Kardashev scale.

The Kardashev scale makes provisions for civilizations far more technologically advanced than any currently known to exist (see also: Civilizations and the Future, Space civilization).

Russian astronomer, Nikolai Kardashev, extrapolated his theory creating the Kardashev scale, which categorizes the energy use of advanced civilizations.

Potential energy sources which would be used by a Type II or Type III civilization on the Kardashev scale include:

The Kardashev scale in fact comes from a theory surrounding humanity's ability to harness universal energy; it was forwarded by Russian astronomer Nikolai Kardashev.

By 2200, it is predicted that a Type I civilization will form under the Kardashev scale, according to Nikolai Kardashev's extrapolation of 1% energy usage growth per year.

Alan Guth has speculated that a civilization at the top of the Kardashev scale might create fine-tuned universes in a continuation of the evolutionary drive to exist, grow, and multiply.

In 1963 Nikolai Kardashev proposed that the then-unidentified radio source could be evidence of a Type II or III extraterrestrial civilization on the Kardashev scale.

Galactia-Colonize beyond the Solar System, expand throughout the galaxy heading to a level 3 on the Kardashev scale, a method of measuring a civilization's level of technological advancement.

The transition between Kardashev scale levels could potentially represent similarly dramatic periods of social upheaval, since they entail surpassing the hard limits of the resources available in a civilization's existing territory.

The ultimate form of space colonization is the Kardashev scale which assumes that a single dominant civilisation will take over all energy on one planet, then one star, then a whole galaxy full of stars.

Consequently, such contact could only be with civilizations rated as Type II or higher on the Kardashev scale, as Type I civilizations would be incapable of regular interstellar travel.

While his technical writings are confined to theoretical physics, his public speaking and media appearances cover a broad range of topics, from the Kardashev scale to more esoteric subjects such as wormholes and time travel.

One proposal for a 10 billion watt interstellar SETI beacon was dismissed by Robert A. Freitas Jr. to be infeasible for a pre-Type I civilization on the Kardashev scale.
