Slight theoretical question that i have difficulty wrapping my head around. Lets imagine a confined room traveling trough space at .9c on a line defined by points A and B. Lets say that in this room is a light source. If this light source is turned on than does the light inside the room still travel at c in every direction? If so then lets assume that the direction that the room travels in is from A to B, length of the room is the same as distance between A and B and finally that the light source is at the center of the room. Now if the light source is turned on when it is in point A, than the light would reach point B faster than c? I'm not aiming at FTL travel, just wondering if light itself could in some cases be made travel faster than c or observed to be traveling faster than c?
