Why Does TIME Stop for Light? — Feynman's Insight

What does a journey of a billion years feel like... if it takes zero seconds?
Light leaves a distant star. By the time it reaches your eye, entire species have risen and fallen. Mountains have eroded to dust. A billion years have passed. But for the light itself? Nothing. No time at all. The departure and arrival are the same instant.
This seems impossible. How can something travel for eons and experience no time? The answer lies in one of the strangest truths Einstein ever uncovered—and it's not what most people think.
In this video, we explore why time dilation reaches infinity at the speed of light, what "proper time" really means, and why photons exist outside of time entirely. This lecture draws on Feynman's celebrated explanations of spacetime from Six Easy Pieces and The Feynman Lectures on Physics, particularly Volume I, Chapters 15–17 on special relativity.

If time stops for light, does that mean light experiences nothing—or everything at once? Share your thoughts below.
