re: #129 Skip Intro

You want something that will really make your head hurt?

Photons from the Sun travel at the speed of light. From our reference point, they take tens of thousands of years to make their way through the layers of the sun before they end their journey by hitting me on the butt at the beach.

However, from the photon’s point of view, time doesn’t exist, and they arrive at their destination immediately after they’re created.

The words “photon’s pov” imply an observer, but no observer can travel with the speed of light, even theoretically, so the issue is basically not meaningful - there is no photon rest frame and there is no photon pov…
