Ekstraordinære påstander krever ekstraordinære bevis.
Fra TV-serien Cosmos: A Personal Voyage (1980), episode 12 - Encyclopedia Galactica.
Extraordinary claims require extraordinary evidence.
What counts is not what sounds plausible, not what we would like to believe, not what one or two witnesses claim, but only what is supported by hard evidence rigorously and skeptically examined. Extraordinary claims require extraordinary evidence.
