Hello, all. I'm trying to wrap my mind around relativity, and I just wanted to make sure I'm not getting it wrong. I'd really appreciate it if anyone were to take the time to chime in on this hypothetical that I think explains it.
Say someone was to put two lasers (in a "gravity free" environment) 599,584,916 kilometers apart and fired them at the exact same time. Imagining that the two laser points are observation points and that the person running the experiment was in the center of these two points (299,792,458 km from either laser), we get three relative perspectives. For the observer in the middle, the two points would appear to meet in the center (taking 500 seconds). For either of the laser points they should appear to meet at the opposite laser (taking 1,000 seconds), since the stationary (from the view of the experimenter) lasers would be moving at the speed of light relative to the laser point.
Do I have this right? I don't really have anyone else to ask... I'm not a student or anything, just curious.
