English Dictionary

c-decay

名詞

不可算名詞

(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).

日本語の意味

（創造論・疑似科学）光速が時間の経過とともに減少してきたという、現代では否定されている理論。宇宙が数千年の歴史しか持たないという創造論の主張を支持するために提案された考え方で、現在観測される数十億光年離れた天体の存在と矛盾する（一定の光速であれば、宇宙の年齢は数十億年となる）。
