Light doesn't have a "speed" as in the usual meaning of the word "speed". Talking about speed requires defining spatial distances and time durations, which are in turn defined or created by the phenomenon of light.
Light doesn't "travel". It's just an exchange of entangled photons creating the concept of time duration and distance.

- zkmon 25d agoThe same way as we talk about it's speed and travel etc - using higher level human perceptions.
