Fizikçiler Işık Hızını Ölçmeyi Neden BIRAKTI? - Feynman'ın Şok Edici Açıklaması | Richard Feynman

In this video, unlike other videos on my channel, we explore why the famous "speed of light" numerical value, which the scientific world pursued for 300 years, climbing mountain peaks and building gigantic machines in its pursuit, has been fixed as a "definition" by scientists, rather than being measured anymore. We examine this 300-year adventure, from Galileo's naive experiment with two lanterns across the valley to Romer's first revolutionary calculations by observing Jupiter's moons, and Michelson's impossibly precise mountain experiments. So, how did the speed of light cease to be a variable to be measured and become a definition of space and distances? In this video, we decipher the elegant scientific logic behind the principle of "if you can't measure it, define it," and why physicists no longer try to measure the speed of light, and why that ultimate number of "299,792,458 meters per second" is the immutable absolute limit of the universe. #light #physics #speedoflight #science #history #alberteinstein #richardfeynman #space #time #mathematics #experiment #feynman
