c-decay

English

Etymology

From c (“the symbol used in physics for the speed of light”) +‎ decay.

Noun

c-decay (uncountable)

  1. (creationism, pseudoscience) The discredited theory that the speed of light has decreased over time, proposed by creationists 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 years away (whereas a constant speed of light would indicate that the universe is billions of years old and so contradict this belief).
