To accept as true the results of a prominent Google return: I googlieve the wavelength of red light to be 650nm. See also: googlief.
Googlief has a complex relationship with belief, as one might accord a googlief of something like wavelengths a higher belief than one's vague recollections, but on the other hand, one might accord low credibility to a googlief that "the most famous man who ever lived" is former FEMA director Michael Brown (a googlief I doubt will survive the month).
(Historical note: 10/10/05 12:24 Hawaii Standard Time, Google says there are no documents with the word "googlief" or "googlieve" in it.)
