This isn't quite true. At a macro level, light slows down. At a micro level, photons travel at the speed of light, get absorbed and re-emitted, and change directions. These effects average out to looking like photons traveling slower.
- User23 3y agoAt the micro level there are infinitely many paths the photon follows and most of them involve it traveling considerably faster than the speed of light. While they cancel out, if you omit them then the calculations don’t give correct results, so they’re happening inasmuch as anything can be said to happen scientifically. If you want to object that that contradicts GR well there is a Nobel prize or ten waiting for whoever squares that circle.
