Absolutes Quote by Henri Poincare
“Absolute space, that is to say, the mark to which it would be necessary to refer the earth to know whether it really moves, has no objective existence… The two propositions: "The earth turns round" and "it is more convenient to suppose the earth turns round" have the same meaning; there is nothing more in the one than in the other.”
