- TL;DR Summary
- We perceive an event because photons emitted from the event pass by and hit us. An event has a start moment and an end moment. An event emitted by a source in a time span of T seconds can be seen as a swarm of photons with a length of T x c. km. which passes us in T seconds with a speed c, because (T x c)/T = c.
Now if two different time durations are measured for one and the same event by two different observers, for example T+1 and T-1 seconds. Is the speed of passage then (T x c)/(T+1) and (T x c)/(T-1) respectively? So not c?
You may be wondering…, and yes, there is an example of it!
