What Is “The Principle,” Anyway?

The Copernican Principle

The Copernican Principle states that the earth is not in any specially favored or central location. The Copernican Principle is a philosophical assumption of modern cosmology. In modern cosmology, it has been generalized, and related to the Cosmological Principle. Based on the Standard Model which is formulated using Einstein’s General Relativity, and specifically with the Friedman-Lemaitre-Robertson-Walker (FLRW) metric, one can say that if one holds the Copernican Principle, and the universe appears isotropic (i.e., no special direction) from our vantage point, then one can infer that the universe would look isotropic from any other vantage point, and be homogeneous. These conditions make up another philosophical assumption, the Cosmological Principle.
The FRLW metric enforces mathematically that such would be true starting from the philosophical assumption of the Copernican Principle. Other metrics and models can be created that could account for the observations, but not require the Copernican Principle to be true.
Assumptions are replete in cosmology because of the intrinsic difficulty in examining everything from one vantage point. An example of another assumption is dark matter.

The Principle”, examines among other things, a special direction found in the Cosmic Microwave background, which has been dubbed “The Axis of Evil”.  What has been found is shocking.

    I would like to see this film. Is there any time soon it will be shown in Phoenix, Arizona or near here. I live in Peoria and would love to see this. I have been waiting patiently for more than a year now to see this film. Is it available to purchase on DVD? Please let me know.

    God bless,
    Glendon
