Warum HÖRTEN Physiker AUF Die Lichtgeschwindigkeit Zu Messen? - Feynmans Erklärung | Richard Feynman

In this video, we explore, in a completely original way unlike any other video on my channel, why the scientific community decided to stop measuring the famous numerical value of the speed of light and instead define it as a fixed concept. It's been a three-hundred-year quest, for which scientists have scaled mountain peaks and built gigantic machines. We examine this three-hundred-year adventure, from Galileo's naive experiment with two lanterns on either side of a valley to Romer's revolutionary calculation through observations of Jupiter's moons and Michelson's experiments of impossible precision on mountaintops. How did the speed of light evolve from a measurable variable to a definition of space and distance? In this video, we unravel the elegant scientific logic behind the principle: If you can't measure it, define it. We explain why physicists no longer attempt to measure the speed of light, and why that final figure of 299 million 792 thousand 458 meters per second represents the absolute and unchanging limit of the universe. #light #physics #speedoflight #science #history #alberteinstein #richardfeynman #space #time #mathematics #experiment #feynman
