Relativistic observations

Lets say I have three points set a few light-seconds apart…points A, B, and C.

A has a circular reflective shell with a one light-second radius, the point is traveling at .95c, and is travelling at a parallell course in respect to B and C. B and C are two light seconds distant from each other.

Now, lets suppose as A comes abreast of B, A sets off a strobe flash of light, which is reflected back to A as A comes abreast of C.

Call the flash and reflection back Events 1 and 2, respectively.

I figure, relative to A, the flash travels out at a uniform rate and reflects back simultaneously.

How does Events 1 and 2 appear to points B and C?

Whaaa…? Could we have a diagram, please?



…C…


…(…A…)…B…

Event 1 (strobe flash)



…(…A…)…C…


…B…

Event 2 (reflection back to centerpoint)

We can simplify observers B & C into a single observer at different time and position relative to A. This site http://casa.colorado.edu/~ajsh/sr/simultaneous.html illustrates how the ring of simultaneous reflections in one frame gets skewed to non-simultaneous events in a moving observer’s frame.

Point B: “What the f*** was that??!!!”

Point C: “Where’s a damn cop when you need one??!!”

Just a WAG.
