Couldn't comprehend statements like "Speed of light is constant and the same for all observers regardless of their motion and direction they measure it" and felt like you're too stupid to understand Theory of relativity?
Well, it's an example of misleading simplification that sounds fascinating, but notice how it always kind of ends with implicit "trust me bro".
Here's a video that should trigger "wait a second" reaction: https://www.youtube.com/watch?v=pTn6Ewhb27k
Why No One Has Measured The Speed Of Light
Physics students learn the speed of light, c, is the same for all inertial observers but no one has ever actually measured it in one direction. Thanks to Kiw...
