i’m in a physics rabbit hole, doing too many problems and now i’m wondering, how is light moving? why?
edit: thanks for all the replies! this stuff is fascinating to learn and think about

It’s a fallout of how electromagnitism works. A changing electric field causes a magnetic field, a changing magnetic field causes an electric field. Given that light is wiggling electric and magnetic fields, it can’t not move.
It’s like asking why a water wave is always moving…you can’t stop a wave, it’s not stable in one position because it’s a dynamic phenomenon that’s driven by it’s own change. It’s only stable if it moves.
