The Kardashev scale is a method of measuring a civilization's level of technological advancement, based on the amount of energy a civilization is able to utilize. The scale has three designated categories called Type I, II, and III. A Type I civilization uses all available resources on its home planet, Type II harnesses all the energy of its star, and Type III of its galaxy. The scale is only hypothetical, but it puts energy consumption in a cosmic perspective. It was first proposed in 1964 by the Russian astronomer Nikolai Kardashev (Kardashyov). Definition[edit] Type I "Technological level close to the level presently attained on earth, with energy consumption at ≈4×1019 erg/sec (4 × 1012 watts) Type II "A civilization capable of harnessing the energy radiated by its own star (for example, the stage of successful construction of a Dyson sphere), "with energy consumption at ≈4×1033 erg/sec Type III Current status of human civilization[edit] Energy development[edit] Criticism[edit]

Enrico Fermi. Enrico Fermi (Italian: [enˈri.ko ˈfeɾ.mi]; 29 September 1901 – 28 November 1954) was an Italian physicist, best known for his work on Chicago Pile-1 (the first nuclear reactor), and for his contributions to the development of quantum theory, nuclear and particle physics, and statistical mechanics. He is one of the men referred to as the "father of the atomic bomb".[4] Fermi held several patents related to the use of nuclear power, and was awarded the 1938 Nobel Prize in Physics for his work on induced radioactivity by neutron bombardment and the discovery of transuranic elements. He was widely regarded as one of the very few physicists to excel both theoretically and experimentally.

Fermi's first major contribution was to statistical mechanics. After Wolfgang Pauli announced his exclusion principle in 1925, Fermi followed with a paper in which he applied the principle to an ideal gas, employing a statistical formulation now known as Fermi–Dirac statistics. Early life[edit] ) vs. energy. Fermi paradox. A graphical representation of the Arecibo message – Humanity's first attempt to use radio waves to actively communicate its existence to alien civilizations The Fermi paradox (or Fermi's paradox) is the apparent contradiction between high estimates of the probability of the existence of extraterrestrial civilization and humanity's lack of contact with, or evidence for, such civilizations.[1] The basic points of the argument, made by physicists Enrico Fermi and Michael H. Hart, are: The Sun is a young star. There are billions of stars in the galaxy that are billions of years older;some of these stars probably have Earth-like planets[2] which, if the Earth is typical, may develop intelligent life;presumably, some of these civilizations will develop interstellar travel, a technology Earth is investigating even now, such as that used in the proposed 100 Year Starship;at any practical pace of interstellar travel, the galaxy can be completely colonized in a few tens of millions of years.

Fermi's Paradox Revisited by Dr. Jeff Kuhn. John Smart (futurist) John M. Smart is a futurist and scholar of accelerating change . He is founder and president of the Acceleration Studies Foundation , an organization that does “outreach, education, research, and advocacy with respect to issues of accelerating change.”. [ 1 ] Smart has an MS in futures studies from the University of Houston , and a BS in business administration from U.C. Berkeley . Ideas [ edit ] Smart is the principal advocate of the concept of “STEM compression,” (formerly "MEST compression") the idea that the most (ostensibly) complex of the universe’s extant systems at any time (galaxies, stars, habitable planets, living systems, and now technological systems) use progressively less space, time, energy and matter (“STEM”) to create the next level of complexity in their evolutionary development. [ 2 ] A similar perspective is found in Buckminster Fuller ’s writings on ephemeralization .
