- yequalsx 12y agoI mean stop it in the sense of the perspective of the photon. I don't know enough physics but I suspect that from the photon's perspective it hasn't stopped. This is because there is no time elapse from the photon's perspective. The other points in my previous post remain valid. I think!
- StuffMaster 12y agoThose experiments always use variations on the word "stop". The speed of light does not vary. In those experiments, "stop" usually means absorbed and later re-emitted.
