C-decay definition

A discredited theory proposed by creationists in order to support the belief that the universe is a few thousand years old that claims that the speed of light has decreased over time, meaning that objects millions of light years away are visible today (whereas a constant speed of light would imply that the universe is millions of years old and so contradict this belief).

Origin of c-decay

  • c, the symbol used in physics for the speed of light, decay
