If Light Never Moves, What Are You Actually Seeing When You Look At The Stars?

Some of the stars above you may not exist anymore. But here's the stranger part: physics says the light from them never aged a single second on the way. So did it travel for a thousand years, or not at all? And what exactly is hitting your eye when you look up? In this lecture, Feynman takes apart one of the most repeated claims in popular physics, and the real answer is weirder than the myth. 0:00 The light that took a thousand years and zero seconds 1:11 You have never seen anything "right now" 5:37 The physics claim that light never ages 7:21 The hidden rule that ties time and space together 15:34 Why "the photon's point of view" doesn't exist 19:54 The rocket that reaches Andromeda in one year 27:46 How many photons actually hit your eye from a star? 33:12 Feynman's strangest idea: light as a handshake through time 38:47 Why every star is slightly in the wrong place 43:10 The star that died 168,000 years before we saw it SOURCES Richard P.
