Albert Einstein | Ich bin zu der Überzeugung gelangt, dass die Bewegung der Erde

„Ich bin zu der Überzeugung gelangt, dass die Bewegung der Erde durch kein optisches Experiment erfasst werden kann“

Albert Einstein, Kyoto Universität, Japan 14. Dezember 1922

"While I was thinking of this problem in my student years, I came to know the strange result of Michelson’s experiment. Soon I came to the conclusion that our idea about the motion of the Earth with respect to the ether is incorrect, if we admit Michelson’s null result as a fact. This was the first path which led me to the special theory of relativity. Since then I have come to believe that the motion of the Earth cannot be detected by any optical experiment, though the Earth is revolving around the Sun."
