For example, the Anthropic Principle is a concept that some respected cosmologists use to explain some of the "fine tuned" features of our observable universe. Final Anthropic Principle (FAP): "Intelligent information-processing must come into existence in the Universe, and, once it comes into existence, it will never die out."įalsifiability Main Article: Falsifiabilityįalsifiability may not even be necessary for science, or at least not be necessary for the search for possible truths.Strong Anthropic Principle (SAP): "The Universe must have those properties which allow life to develop within it at some stage in its history.".

  • Weak Anthropic Principle (WAP): "The observed values of all physical and cosmological quantities are not equally probable but they take on values restricted by the requirement that there exist sites where carbon-based life can evolve and by the requirements that the Universe be old enough for it to have already done so.".
  • The three primary versions of the principle, as stated in The Anthropic Cosmological Principle by Barrow and Tipler (1986), are: Tipler (Oxford University Press) published their book The Anthropic Cosmological Principle, in order to deal with the seemingly incredible coincidences that allow for our presence in a universe. Brandon Carter had the honesty to proclaim that humanity did indeed hold a special place in the Universe, an assertion that is the exact opposite of the now universally accepted theory that bears Copernicus' name. The Anthropic Principle was first defined in 1973, during a symposium commemorating Copernicus’s 500th birthday. Proponents of intelligent design draw support from this fact because it strongly suggests that the cosmos has been specifically designed. In the early 1970s a scientist named Brandon Carter dubbed this line of reasoning the anthropic principle. We appear to live in a universe dependent on several independent variables where only a slight change would render it inhospitable for any form of life. Everything from the particular energy state of the electron to the exact level of the weak nuclear force seems to be tailored for us to exist. The very presence of life within the universe is reliant upon a large number of extremely improbable events, and even the slightest alteration would make it impossible for life to exist. It is often set up as being in opposition to the Copernican Principle. Anthropic comes from the greek word anthropos (Man).

    It originated from observations that the earth uniquely and perfectly meets the requirements for life, and more specifically human life.

    It is used to develop scientific explanations in cosmology. The anthropic principle is the claim that the Universe was prepared from the first moment of existence to the emergence of life as a whole and especially of human life.
