Noun

1. {{lb|en|creationism|pseudoscience}} The [[discredited]] [[theory]] that the [[speed of light]] has decreased over time, proposed by [[creationist]]s in order to support the belief that the [[universe]] is a few thousand years old even though there are objects visible today that are billions of [[light year]]s away (whereas a constant speed of light would indicate that the universe is billions of years old and so contradict this belief).
