Absolute/Movement/Absoluteness/The Absolute/Philosophy/Feynman/FeynmanVsPhilosophers: it is not meaningless to speak of speed. - Our inability to detect absolute motion comes from experiments - not merely from pure thought. - Even in Newton's time, everything was already relative. - No one cared, because only Maxwell's equations seemed to make it possible to measure speed from within.
It is true that absolute motion is meaningless. - It is meaningless, because it cannot be proven. - Not the other way around. - It is meaningless, because it cannot be defined. - Feynman: Some philosophers argue that motion cannot be proven without looking at the outside world. - That is not true. - Only linear constant movement cannot be proven without consideration for the outside world. - Example: Internal evidence of Earth's rotation: Foucault pendulum.
