주장 CE 411.1:

Physicists Joao Magueijo at London's Imperial College and Andreas Albrecht at U. C. Davis say the speed of light immediately after the beginning of the universe was many times faster than it is now, and it has been slowing ever since.

런던 제국 대학의 물리학자 Joao Magueijo와 U. C. Davis 대학의 Andreas Albrecht는 우주의 시작 직후의 광속은 현재의 몇배가 되며 그 이후로 계속 줄어들었다고 말했다.

답변:

  1. Albrecht and Magueijo [1999] have hypothesized that the speed of light may have been much faster (up to 1069 times faster) in the very early universe. This is a theoretical model proposed as an alternative to the inflation theory of the early universe to explain why the universe is so uniform. The increased speed applies only to the inflationary stage of Big Bang models, which means only the first 10-43 second or so. Their theory has not been verified by observation.


    Albrecht 와 Magueijo [1999] 는 빛의 속도가 우주의 초기에는 매우 빨랐다는 가설을 세웠다(1069배까지 빠르다).  이것은 왜 우주가 이토록 균일한가에 대한 설명을 하기 위해서, 초기우주의 팽창론의 대안으로 제안된 이론적인 모델이다. 증가된 속도는 빅뱅 모델의 초팽창 단계(inflationary stage)에서만 적용되며, 이것은 최초의 10-43 초 정도에 해당한다. 그들의 이론은 관찰로 입증되지 않았다.
     
  2. Other evidence shows that the speed of light has been constant for a long time.

    다른 증거들은 상당히 오랬동안 빛의 속도가 일정했다는 것을 보여준다.
